Why does an allele from the father only promote increased pup growth and increased care by the daughter mother?

-Tradeoff-increased pup growth in current litter reduces number and fitness of future litters. Since father of current litter might not sure future litters, father's gene favor investing more in growth of current litter (the one he sired) than would mother's genes. Called intragenomic conflict

What is Trivers' explanation for the occurrence of parent-offspring conflict? Give examples of such conflict in non-human animals

-parent equally related to all offspring and should distribute resources evenly. But each offspring benefits more from having more resources. Each offspring should attempt to gain more from parent than parent will attempt to give *Examples of conflicts* Weaning conflict-mammalian young try to suckle longer than mother permits them to suckle Chimpanzees-Mothers wean infants between 4 and 6. Chimpanzees become fully independent between the ages of 6-9. Weanee gave a predator alert scream to coerce mother to carry it

Experiment: Sexual Selection and assortative mate choice

- Experiment done by Javan Munin Attached a red colored feather to a male head to see if female preference mattered in sexual selection. - Control: no feather - Experiment: red feather Females prefered males with red feather - depending on female choice, colors will grow in population - traits that are more appealing to females for sexual selection, will grow in the population since they will be passed down the most. This will create at first a microevolution and then probably grow into a macroevolution and take over as a dominant sexual trait within the species.

Marine organisms and sound-Melon

Genomic imprinting example

Knocking out paternal copy of mest gene reduces pup growth. Females with knockout failed to care for young. ○ Why does an allele from the father only promote increased pup growth and increased care by the daughter mother? ○ Answer: Tradeoff-increased pup growth in current litter reduces number and fitness of future litters. Since father of current litter might not sure future litters, father's gene favor investing more in growth of current litter (the one he sired) than would mother's genes. Called intragenomic conflict

Be able to identify the structures in the eye and ear that we discussed in class and be able to describe their function and any unique features relative to mammalian (or human) structure and function.

Large Eyes, more variable shape -Flat Hered. (Common) -Globular. Hunters. Hawks -Tubular. Nocturnal. Owls -Birds cant move eyes like ours. Eyes place on side of head Monocular Vision:area seen with either left or right eye. - due to them being prey animals, birds have low level binocular vision (direct frontal vision) -Pigeons can see around but lack binocular vision.Depth perception low. Binocular vision: See with both eyes. Owls have. Pecton Vascular dark material in eye.(amount of folds and location depends on taxa) Nourishes eyes. no blood vessels in retina all in PECTEN. - Acute vision, more vision, more efficient. - Know funtion at the most basic level. - Hypothesis: reduce glare, navigational function, dark mirror (see things close to sun), and regulate eye temp. and hydrostatic pressure. Other reasons for pectons possibly: -Reduce glare -Navigation function -Dark mirror for viewing objects close to sun -regulate eye temperature and hydrostatic pressure -We have blood vessiles in Rectina, birds don't and its in pecton. Sclerotic ossicle - little bone ossicles rings around the eye that help adjust the cornea. We only have one muscle. -They have additional muscle of cramptons muscle Cramptons muscle Birds have million per square of cones. -Produce sharp images. -See prey easy. - muscle used to move the sclerotic ossicle - mammals have 1 muscle and birds have 2 for adjustment Retinas - 2-5 times as many cones - detect fast movement Fovea Central Fovea:where eye is focused. -Some birds who move fast have central and teporal - 2 in eyes (maybe three in some species) - area of the eye where cones are concentrated for better focus - hummingbirds have 2 Oil Droplets -resting on top of cones is a drop of oil that is clear or has carotenoid in it. This gives the bird's eye color. Under research. Birds have two kinds of vision... Binocular vision - see with both eyes, - predators will have more binocular vision then prey animals Monocular vision - see with either left or right eye Avian Auditory system -no external structures - birds do not have a pinna (flap around the ear) - funnel sound by modified feathers around the ear canal (no barbules) -one ear bone,stapes (columella)Similar to our hearing -semicircular canals.

Examine the patterns of sexual dimorphism within mating systems of wildlife and relate this to idea of Trivers on which sex should be the 'choosiest'?

Parental condition is associated with offspring condition; Differences in offspring condition will persist into adulthood; Being in condition differentially affects the mating success of one sex more than it does the other. Triver's idea on which sex should be the choosiest stems from parental involvement. The female's gametes are often much larger than the male's gametes and because of this males often have more offspring than females do. Because of both of these things females should be the choosiest. Since females because they are investing more into the offspring.

Describe the structure of the syrinx and explain how it works.

Syrinx operates with nearly 100 percent physical efficiency to create loud, complex sounds and can produce 2 independent songs simultaneously. Located in the body cavity and the junction of the trachea and the two primary bronchi. Sound is caused by the vibration of the air column as air passes through the syringeal passageway. Projections called the internal labium and the external labium constrict these narrow passageways. One each side of the syrinx is the internal tympaniform membrane. Pressure in the interclavicular air sac pushes the tympaniform membranes of the syrinx into the bronchial air space. The opposite sides of the syrinx can produce different songs simultaneously. Syringeal muscles control syrinx action during song production. Nonpasserine birds have two pairs of narrow muscles on the sides of the trachea above the syrinx called extrinsic muscles . Oscines have 6 pairs of intrinsic syringeal muscles in addition to extrinsic muscles. The intrinisic syringeal muscles originate within the syrinx and intsert onto the bronchial rings, the internal and external tympaniform membranes and the syringeal cartilage

If surveys imperfect p<1, classifying sites with no detections as unoccipied will

will underestimate true occupancy because some proportion of sites are likely to be occupied even though the species was never detected

What is the evolution analysis?

• focuses on the phylogenetic/evolutionary history of behaviors

Attribute data

•Consist of nominal, ordinal, interval, and ratio data just likenon‐spatial data •Can be points, lines, areas, or surfaces (3D) •In geographic information systems (GIS), attribute data is associated with position data in database Ex: -Elevation, slope, aspect •Land use/cover •Soil type •Landmarks •Average annual primary productivity

Immersive

•Mimic habitat for animals and visitors •Multi-species displays where possible •Barriers = often more natural or even non-existent

Assumption:Equal detection probability:behavior

(b) detection probability changes in response to initial capture -trap happy: p< c -trap shy: p> c -no behavioral response to capture:p= c *Behavior Response* With the information in encounter histories, and assuming closure, we can separate detection probability into two parts: 1. p = capture probability- probability of initially capturing an individual 2. c = recapture probability- probability that a marked individual is recaptured

Identify precopulatory mechanisms of mate competition. Identify postcopulatory mechanisms. Be sure to know what is meant by each.

*Precopulatory competition: Before copulation, includes:* -scramble-find females quickly and mate with as many as possible, first one in wins -mate guarding-males guard immature females until they are ready to mate (rare) -endurance rivalry-selection for traits that improve endurance-(longer stay at breeding sites will get more females)-"the last one standing" wins -contests-compete for either direct access to mates or monopolize resources needed by the female, the "baddest one" wins-sometimes actual combat or sometimes ritualized display-selects for better WEAPONS *Postcopulatory competition: after copulation, includes:* -Sperm competition-sperm of second male may displace or incapacitate sperm of the first male -Mate guarding-after copulation, guard female until eggs are laid-to make sure no other male can interfere infanticide-killing off the offspring of another male

What do evolutionary psychologists predict about the differences between mate choice in human males versus females? Why? What is predicted about patterns of jealousy? Is there evidence to support any of these predictions?

*Predictions* Both sexes will give weight to 'good looks' and good care-giving. BUT ...Females will give more weight to partners who provide good care-giving (males with wealth, experience, status). Males will give more weight to partners who are young(and fertile) and have 'good looks'which indicate 'good genes' for health and child-bearing *Why* Because Females prefer older men in personal advertisements.Males prefer younger women in personal ads *Patterns of Jealousy* For men: female's sexual infidelity risks parental investment in another male's offspring. For women: male's emotional involvement with another woman risks lost parental resources. *Evidence* Expect evolved sex difference in jealous mind: •male should respond primarily to cues of sexual infidelity. •female should respond primarily to cues of extra-pair emotional involvement

What are the differences between the human and avian respiratory systems? Describe how these differences in form lead to differences in function.

-require more oxygen. Exchange CO2 for O2. For birds it is different. -air sacs- are in bones all through body . -lungs different than ours. Ours is an airbag and surface exchange never fully expels air or lungs collapse. Birds lungs are dense surface exchange where air sacs pushes air around. Very dense gas exchange. We leave 20% of air we dont exchange

Intrinsic Qualities

-resource holding potential -motivation to win -body conditions -"Birds have weapons" Example:Claws, Rooster, Cassary -As body mass increases, territory is more needed

Oil Droplets

-resting on top of cones is a drop of oil that is clear or has carotenoid in it. This gives the bird's eye color. Under research.

What aspect of male traits does Zahavi's handicap hypothesis seek to explain? What must be true of a courtship signal for it to evolve as a handicap, according to theoretical models?

-seeks why the traits for mate choice are so exaggerated-to the point of possibly being a handicap Exaggerated male traits are essentially handicaps. Female prefer males with these handicaps...... because such males have demonstrated an ability to survive despite their handicap -it is costly and only the best males can afford it-it prevents males from "cheating"

Genetic differences in behavior in nature due to small differences at many loci. However there are exeptions. What are they?

-sexual differences in behavior .-male and females can result from genetic polymorphism. some have simple genetic basis. Example: fruitless locus in drosophilia. -Original fru phenotype involve males that do not mate successfully. They even court other males, forming a chain. -For one fru transcript, gene splicing is different in males vs females. -males spliced transcript produces a protein, in females protein is not made. FruF males court females less and rarely mate. FruF males court males, forming chains. FruM females court females. Conclusion: fru is a sexual behavior gene switch. Meaning, sexual differences due to a single gene has large efffects.

What are some behavioral responses for keeping cool?

-shunt -Gular Flapping expands bright red breast area in order to increase surface area and increase evaporative cooling. this is a change in temp. -Other birds open mouths to plant.

Alternative Reproduction tactics squirrels

-year 1 males had less copulation's than year 2 Fox squirrels: When Females are closed to being receptive, male follows female for about 5 days. -Females smack males away until the day she is receptive. -Other males fight for access to the females. -Some satellites are around -Find out female is in estrus from pheromones -Because her pheromones have been released in an area, he cannot pinpoint where she is, so he has to rely on sight and sound. Follow any kind of movements like crow or baseball in attempt to find her - females groom themselves and may find a plug and attempt to remove it. -females may eat plug for protien source

Tinbergen addressed a framework of approaching questions in ecology, behavior and conservation. First, address the development of these ideas and then apply these to the question of 'Why do mammals display flehmen?'

1)What is a cause of a behavior: causation-focus on the mechanistic cause of behavior- physiological, hormones, season 2)how does a behavior develop? Ontogeny-how they learn, is it instinctive, practice and make own song? Focus on the development of behavior. 3) what is the survival value of a behavior?-functional. 4) how did a behavior evolve? Evolutionary--focus on the phylogenetic/evolutionary history of behaviors. Causation and ontogeny are proximate cause- its the how question. imminent cause responsible for behavior. Functional and evolutionary are ultimate causes-its the why question. -flehmen response- curle the lips of upper lip. They are detecting information by smelling. Have a vomeronasal organ or jacobsons organ and allow molecules in the environment to be concentrated. The purpose is to concentrate resources and access is. Can detect if chemical is present or not. Be able to detect mates, if other females are present, determine if dominant or subordinate. Tied to olfaction communication.

Why might a lek mating system evolve? What factors influence males' abilities to gain copulations in such a system?

1.)Hotspot model: males gather where most likely to find females. Not a good explanation though 2.) Hotshot: males gather around best male to increase their chances of being noticed with large populations 3.) Female preference: females enforce leks. Prefer to visit. Prefer large clusters of males. MOST SUPPORTIVE! Factors that influence: -Competition among males are high -intense competition ranks male in a dominance hierarchy and determines which males sire most of the next generation -By mating with dominant male, a female may obtain for her offspring the genes responsible for the males superior traits. -In Sage Grouse successful males are 1)socially dominant birds 2)hold central positions on lek 3)are more active and visually or vocally attractive. Generally better in health.

How do the descending motor pathway and anterior forebrain pathway relate to song development?

Descending motor pathway: - regulates song -stimulation of the motor neurons in this pathways contracts the syringeal muscles that control tensions and dimensions of the vocal tract -Descending motor pathway transmits nerve impulses from the high vocal center (HVC) of the hyperpallium layer of the fore-brain to the robust archopallial (RA) and intercollicular nuclei, then to the tracheosyringeal motor (hypoglossal) neurons (nXllts) in the hindbrain, and, finally through the tracheosyringeal motor neurons to the syringeals muscles that control the syrinx. Destruction of the HVC nuclei renders a songbird mute Anterior forebrain pathway: -Plays a central role in song recognition and song learning in oscine passerines -unites the song motor-control centers with the auditory centers in the forebrain and midbrain. -may also play a secondary role in actual control of song production. -LMAN controls the learning of songs -anterior fore-brain pathway connects the HVC to area x, which plays a critical role in the crystallization of male song,with feedback loops to the auditory centers of the forebrain (LMAN) and midbrain (DLM) as well as the motor pathway through the Ra nuclei. Field L is the auditory region of the forebrain. It projects to the HVC and the RA nuclie

Parental investment vs parental care

Example: Parents help young acquire nutrients via Parental investment -yolk-filled eggs -body secretions (milk, mucus) -bringing food to young -teaching young to get food -laying eggs at food sources Parental care -bringing food to young -teaching young to get food -laying eggs at food sources

Alternative mating strategies:Frogs

Example: Satellite males in frogs Males hang out in the vicinity of a holder of high-quality territory and mate with females as they move to the territory

Give examples of male-male contests. Explain why contests usually begin with ritualized displays, before sometimes (though not always) escalating to physical combat.

Examples: Hippos, Snakes, Gorillas, elephant seals, Red deer. Some contests are physical well some are ritualized (snake example) . Gorrilla example: Mountain gorillas live in groups, some groups have multiple males. Male dominance is established through aggression. Dominance determines male mating success. Elephant seals example: fighting established dominance status. Dominance status. Dominance determines male mating success. Red deer: stags defend grazing areas where hinds visit. Male mating increases with the size of male's harem Contests being with ritualized displays because of low risk of injury

What is a territory? What are the costs and benefits of defending a territory?

Fixed area defended continuously for some period of time. The 'owner' benefits by having access to a resource (or better quality resource) than they would otherwise Costs of territory -energy lost -injury -increase with habitat size -High quality always preferred over low -High predation risk due to revealing fighting Benefits of territory -Keep territory -get lots of resources -more insects

How sound travels in the ear

Fluid in inner ear and when sound waves comes through, it brushes the hair, picks up the movement, and helps the sound travel into your ear drum. - the hair cell have different lengths for different wave lengths - people who cannot hear well, are due to damaged hair cells

Draw the curve for the law of diminishing returns and relate this to these 4 behaviors: 1.) time that an individual should spend foraging in a patch, 2.) time that an individual should search for a mate, 3.) size of a territory and 4.) time spent studying for final exams.

For all of these scenarios the result will be very similar. If you spend a longer time foraging and searching for food than what is needed, then the costs will exceed the benefits. And if you spend less time foraging and searching for food then you won't gain enough energy to survive. In this case the costs will also exceed the benefits. So the individuals must search for food for a certain amount of time in order to gain energy and gain a benefit. The benefits of foraging is best between the two areas where the benefits exceed the cost. Also, we expect that the most common amount of time used for foraging is where we see that the difference between the cost and benefits are at its greatest. This is where the benefits exceed the costs and is at its maximum amount, which is somewhere in the middle of the graph. This logic can be applied to the other examples. The cost of territory size increases exponentially because the effort to travel the territory increases, thus depleting energy from walking and spending less time eating. As territory size gets bigger there is not as many benefits. The cost increases exponentially because the area increases by r2. For example if the area increased by 50 meters in all directions, then the animal would have to walk 50 meters in all directions and defend that territory. If the habitat is becoming more poor quality (such as a fire comes through and burns down trees that had seeds) then the animal has to travel greater distances to gain energy in order to receive the benefit; so territory size should increase. If the quality of the habitat is increasing then the place where we maximize the benefit vs. cost moves lower on the graph. Territory size gets progressively less---don't need to travel as far to receive the maximum benefits.

How does a female directly influence their male offspring's reproductive success?

For mammals, this includes the quality milk given to the offspring.

What factors make exclusive male care more likely to occur?

Giant waterbugs show exclusive paternal care. Males aerate eggs and defend them from predators Males are the carrying sex because eggs are glued to male's back immediately after he mates with female and *paternity is generally assured* second explanation: males that carry some eggs more likely to get a second mate

You wish to estimate abundance of box turtles in an area with two vegetation communities,grassland and oak savanna, both covering the same amount of area. You know from previous work that detection probability of box turtles in grasslands = 0.60 and in oak savannas = 0.40. You survey turtles on 10 plots in each vegetation community that cover 10% of the total area covered by each vegetation community. You count a total of 120 turtles during survey on plots in grasslands and a total of 80 turtles on plots in oak savannas. Estimate abundance of turtles (a) in each vegetation community and (b) across the entire area. Show your work

Grassland c=120 p hat=.60 N hat =120/.60(.1)=2000 Savanna c=.80 p hat=.40 N hat=80/.40(.1)=2000 Overall 2000+2000=4000

Why pheromones are used

Health/fitness, sexual selection of mate and the avoidance of incest, maturation, kin recognition, hierarchy, marking, deception, aggregation, intruder alarm

Reciprocal altruism

Help if you help back later. Risky -More likely if -you will interact with the same individual later many times, in which you can reward or retaliate -you can recognize individuals -If the game is repeated and individuals recognized previous partners, and choose to cooperate or defect each time, Then altruism and defection can be reciprocated:cheaters don't do well and altruism evolves.

Kin-selection

Helping relatives increases your"indirect fitness' -The more of your genes are in a relative, the more interest you have in helping them -The more an altruist helps relatives, the more likely it is that the gene for altruism will become more frequent in the population

Assumption: Equal detection probability:Heterogeneity (h)

Heterogeneity (h)- inherent differences in detection among individuals perhaps due to: - differences in sex or age - social dominance - differential vulnerability to capture, such as fish size when electrofishing The key to understanding heterogeneity is to recognize that we do not know (or have no identified) why detection probability varies among individuals This is why it is often called unmodeled heterogeneity

Anthropogenic

How many genes encode behavior? Cricket example

In crickets, often the male sings, attempting to attract a female. Males make sounds by drawing a "file" on one forewing across a scraper on the other forewing F1 songs: 1. Songs are a blend of parental songs 2.F1 songs depends on what species contributes which parent. Backcross songs: 1.Songs are blend of parental and F1 song. 2.If backcross repeatedly to parental species, song resembles parental species' song more and more All results together suggest that: 1.Song production is polygenic 2.Song production is sex-linked, meaning some genes for traits are on x chromosome One final result: If hybrid females are offered a choice between a hybrid male song and a parental species song , hybrid females prefer hybrid male song. Proposed: genes involved in both song production and song response. Genes may be used to produce set of instructions to produce the song, and for preference of song. Have to be on both chromosomes.

Do differences in nature reflect genetic differences?

In lab we can see types. In nature sometimes types are seen. -Occurrence of types in nature is polymorphism But usually, variation in nature is continuous. Variation forms a "bell curve", also called a normal distribution. Example: water striders-some can fly and some cant which are genetically based Genetically based variation or variation due to environmental factors must ask where genetic relatives are found in the distrubution.

What are the adaptations that enable brood parasites to deceive their hosts and what are the counter‐ adaptations of the host to escape such parasitism?

Intraspecific Brood Parasitism Deceive hosts -Lay eggs in nests of their own species nest when hosts are away. Causes host to think parasitic eggs are her own and laid fewer eggs herself. Counteractions -Breeding females guard by removing foreign eggs deposited before they themselves lay eggs. After female starts her clutch, it cannot distinguish the parasitic eggs as a parasitic female will remove of the host's eggs and replaces it with her own. Obligate Brood Parasitism -lay eggs in nests outside their species Deceive hosts: -thick shells are resistant to cracking as females drop their eggs into deep nests. -larger eggs and chicks for faster growth. Shorter incubation periods. -specialized birds that target specific hosts by mimicking eggs of their host -mimic eggs because females are w linked. Egg determines sex and egg coloration is w linked. Females carry genes for egg types on the female W sex chromosome -chicks are aggressive and may shove unhatched eggs of its host out of the nest -imitates host nesting begging call and mouth Counteractions of host -reject eggs even if it means damaging their own eggs -leaving the nest or bury the entire clutch and laying a fresh clutch on top

To test for use of a time-compensated sun compass,

Investigators engaged in clock-shifting. -Raised a late-shifted group which 'thinks' it's 6am when it's really noon. -Raised a control group which 'thinks' it's noon and it is (!). Release both groups at noon, real time 6 am ,noon 6 pm. At noon in northern latitudes, sun is in the southern part of the sky. Hence, at noon, a butterfly attempting to fly south should fly in direction of the sun. -Control butterflies headed towards sun, as expected. -Late-shifted butterfly 'thinks' it is 6 am when it is actually noon. -At 6am, sun is in east. So butterfly should fly 90 degrees away from sun.BUT... it is actually noon and sun is really to the south. -So... the butterfly ends up flying WEST

Hatchlings maintain a highly directional outward-bound course. HOW?

Loggerhead sea turtles hatching from eggs on beach can use three cues 1. Dunes and associated vegetation from a dark silhouette 2. Beach slopes down in the direction of the water. 3. Ambient light is reflected from the ocean, making that region brighter Using this setup, hatching loggerhead sea turtles use both slope and brightness to move to the water Hatchlings tethered in the arena swam into approaching waves whenever waves were present. • Hatchlings tethered in the arena when the water was still oriented in random directions since waves run parallel to the beach, swimming into the waves moved them towards open ocean

Remarkably, hatchlings maintain an outward bound heading even after the waves disappear. HOW?

Magnetic compass -hatchlings tethered and allowed to swim towards light in east. Light then turned off -Hatchling maintained an easterly orientation, even in total darkness suggests use of some cue present in dark To test: electric coil placed around apparatus. Coil generates magnetic field Field in same direction as earth's: Hatchlings tethered and allowed to swim towards light in the east. Light then turned off. Hatchlings again moved east, even in total darkness. Field reversed in direction:When light was extinguished

Know how the male and female reproductive tracts of birds differ from mammals and be able to identify the main reproductive organs and structures and their functions.

Male Reproductive Tract -Testes bigger in breeding season-May be adaption for flight -Entire reproduction tract englarges -Vas Deferenes:the duct that conveys sperm from the testicle to the urethra. -Seminal Vesicle: expanded bases of the two ductus deferentia, which swell and accumulate semen waiting discharge -Cloaca:stores sperm -Urodeum:Is the middle part of the cloaca.t has the ureteric opening -Polyandry has largest testes -Next highest is colonial species that are monogamous -After is solitary monogamy -Leks have smallest testes Female Reproductive Tract -1 Ovary-left and 1 oviduct on left to reduce weight -eggs in ovary are at different developments -Yolk-for nutrition of embryo will be added on ovary and take 5-15 days. 21-36% Lipid and 16-22% protein. Rapid Yolk development phase because "tree rings" in light shows days it took for female to yolk eggs. -egg is released from Ovary and makes its passage through oviduct. May take 24 hours. -Oviduct includes Infundibulum, Magnum, Isthmus, Uterus, and Vagina - Sperm needs to reach infundibulum to fertilize -Ovum reaches Magnum where first layers of albumen will be added- -Albumem is 90% water and 10% protein. Functions as water supply, shock absorbor, insulator, and protects against bacteria. -Then it reaches Isthmus where inner membrane, outer shell membrane, and albumen will be added -Next it will reach uterus.albumen, hard shell of calcium carbonate, and pigments will be added -carotenoids make colors of yolk -Last is the vagina which is the muscle for expelling the egg -If making 2 eggs, it can crack in body. Very dangerous

Arizona examples of mating systems (Add all when slides are up)

Monogamy -Mexican Wolf -Prairie Vole Polygyny -Elk -Proghorn, Mule Deer, WT deer

Describe the breeding systems discussed in class and give examples.

Monogamy: The predominant avian mating system. Pairs stay together and share parental work. 90 percent of birds use these system Polygamy:mating system including multiple mates. Only 3 percent of birds practice this Types of polygamy: 1) Polygyny: males control or gain access to many females. About 2 percent. Example: Sage Grouse 2) Polyandry:Females control or gain access to multiple males. Males may tend to clutch. Less than 1 percent. Females are 25% larger than males. Example Spotted Sandpipers. Males take care of young and incubate. At first monogamous until female finds another mate. 10 percent cuckoldry due to stored sperm. Primary males have higher paternal obligations. Second choice males get help from females. 3) Polygynandry: Several males and females mating. Example is the Acorn Woodpecker. Very rare.

We have discussed roads on several occasions in this course and outlined a myriad of ways that roads may impact the behavior of wildlife. Examine these influences and then discuss specific ways that such impacts can be mitigated.

Noise can be a big problem from roads. Something we can do with this is design vehicles that have a better muffler. This will make them quieter. A direct impact that roads have on animals is mortality. Slow moving animals such as frogs, snakes, and turtles are a high risk of being killed. Rabbits, deer, armadillos, and squirrels are also at risk. Usually they will exhibit a freeze response when startles. Deer will stop and think "do they see me?" Armadillos and squirrels will freeze then jump up and get into a ball whenever they are startled. But this tactic does not work on the road. Deer will also be near roads to evade predators and forage on the road. A lot of animals will avoid roads due to traffic noise, gap avoidance, and edge avoidance. So let's think of roads as membranes. How are we going to make roads less of a barrier and be more of a permeable membrane? We could make crossing structures to mitigate these issues. We could make underpasses and overpasses. We could make tall structures for flying marsupials. Salamanders just need a tube that has water and some litter. Build underpasses for large and small animals. Put branches in the underpass so that smaller mammals will pass through. Otherwise they would be too scared to go through the underpass.

Instantaneous (snap-shot)

Notes whether a behavior is occurring at the instant of a regular sampling interval -Pros: economical, large sample, less subject reactivity -Cons: unavailability of subjects and observation window -behavioral type EVENT

Proportional to size

Number of sample units selected from each stratum is proportional to the size of each stratum - sample size for stratum i = Ni/the sum of Ni for all strata - appropriate when survey costs are approximately equal in each strata and we have no other information about the population

Organ that allows the uptake of information from odor particles in the air - pick up sent and rub it against the organ

How environmental traps formulate

Original environment have an original cue and original repsonse which makes expected results and no trap. In a new environment, the original cue and original cue result in an evolutionary trap and unexpected results

How many genes encode behavior?Orimia flies example

Ormia flies parasitize Telegryllus crickets in Hawaii. Orima uses male chirps to locate them and then ay eggs on cricket. Maggots cause the death of their host. In 2003, a mutation arose in Kauai population that rendered males mute. Called Flatwing, the new form is protected from parasitism, but must use other cues to mate. Mutation increased from to 90% in 30 generations. Natural selection! • Big picture: Song production and song acceptance is polygenic

What are some examples of sensory feathers:Protective?

Ostriches "eyelash" is made of feathers to protect eyes. Brissels for ravens but purpose is not know.

Imperfect Surveys

Our goals for management and research often focus on characterizing populations of plants and animals where it is impossible to ensure that we detect all individuals present on the area that we survey.

Why are a higher proportion of bird species monogamous compared to reptiles and mammals?

Outcome depends on -resource distribution -relative competitive ability of both sexes -population structure Monogamy gives opportunity for male parental care because female detach egg and offspring can use both parents vs mammals where young develops in female body. Reptiles lay their eggs and leave offspring alone. Males can defend territorial space and secure food and supplies for female and young.

What are the unique sensory adaptations of owls and turkey vultures? Explain in detail how structure is related to function for these adaptations.

Owls have binocular vision and better hearing than humans. Avian auditory system for owls -Asymmetry of ears on vertical -Facial discs -High number of auditory neurons - extreme feathers around ear - "naked" feather at front of eat - really dense feathers at the back to funnel sound better - ears offset to get more range of hearing for hunting Vultures have a great sense of smell and can find dead animals easily. Very complex nasal cavity and has a concha with a surface covered in scent receptors. Vultures can be used to find oil leaks.

Parties mirror each other's social attitudes:High degree of immediate contingency-"If you're nice, I'll be nice"

To understand negative frequency-dependence in mimicry, we need to look at things from the predator's perspective-pigeon example

Pigeon has worms to eat that look similar but one is poisonous. -Pigeon gains 5kcal when eating worm but can lose -15 kcal when eating poisonous worm -If pigeon has 16 worms to eat, but all of them are poisonous it will be described as 16 x(-15)+0x5=-240, essentially killing the pigeon -if pigeon has 16 worms to eat, but all of them are non-poisonous, then it will be described as 0X(-15)+16(5)=80 -If you have 4 good worms and 12 bad worms, you break even 4(-15)+12(5)=0 -the more costly bad worms (models ) are relative to their good worms (mimics) , the more good worms (mimics) there can be before mimicry breaks down.

Explain the polygyny threshold model. When are females expected to mate with an already mated male?

Polygyny depends on variation in territory quality -Do better in higher quality territories -Birds that nest colonially in "safe" trees or in marshes with abundant or easy-to-find food tend to be polgynous -Females of this care for young with little or no help from males -Females join harems because they do better than when paired with one male on a territory of poorer quality -Polygynous males control better-quality territories than unmated or monogamous males in the same area -central territories are protected from predators -these territories conceals nests -edges of territories are dangerous, females would rather go with males with better territory

____________ is the entire collection of entities about which we want to make an inference or draw a conclusion.

Population

If siblicide reduced parental fitness, why wouldn't parents prevent it?

Possible reason for hyenas: young are deposited in aardvark burrows. young are safe from predators, but mother cannot get them sharks: sandtiger shark siblings kill siblings in the womb and mother is helpless. Carnivorous habit facilitates siblicide

Is siblicide necessarily contrary to the interests of the parents? Explain.

Possible reasons to not prevent it: Young hyenas are deposited in aardvak burrows and they are safe from predators but mother cannot reach, also sharks babies in womb of mother kill each other and mother is helpless Some parents resolve conflict by making clutches smaller such as parasitic wasps

How did tetrachomacy evolve in birds?

Explain how resource distribution influences the evolution of mating systems. How do the red‐winged blackbird and dunnock examples provide insight into this problem?

Red-winged black bird -Do better in higher quality territories -Birds that nest colonially in "safe" trees or in marshes with abundant or easy-to-find food tend to be polgynous -Polygynous Red-winged black birds control better-quality territories than unmated or monogamous males in the same area -central territories are protected from predators -these territories conceals nests -edges of territories are dangerous, females would rather go with males with better territory Dunnock Outcome of sexual conflict depends on: - resource distribution - relative competitive ability of both sexes - population structure - variation in resource availability and relative competitive abilities - Females always defend exclusive territories; whereas males do not - Males sharing a territory are not related and have a strict dominance hierarchy - Size of female territories reflects resource availability and competitive abilities - Dense hedgerows may have enabled the evolution of such complex mating strategies

Ecological Selection

Refers to natural selection minus sexual selection, i.e. strictly ecological processes that operate on a species' inherited traits without reference to mating or secondary sex characteristics. Natural selection will push the ecological selection towards certain seed types

First line of evidence of comparative approach in mobbing

Related species, differing risk Example: Herring gull -nest in Open -Predation risk High -Mobbing observed Kittiwake gull -nest on cliffs -predation risk low -no mobbing strong support for adaptation hypothesis

Second line of evidence of comparative approach in mobbing

Related species, similar risk -Herring gull - black-heading gull -laughing bull -all nest in open -predation risk high for all -mobbing observed in all This supports for adaptation hypothesis, but weak because all species may mob because common ancestor did so. Effectively, a single data point.

What is the major disadvantage of systematic sampling compared to simple random sampling?

Risk of bias

What is meant by a tradeoff between current and future reproduction and how does it shape a) parental care and b) parent-offspring conflict.

Role of future reproduction: species that benefit more by future reproduction should invest less in care of current offspring *shapes parental care by* investing less care in current offspring such as bringing food to young, teaching young to get food and laying eggs at food sources *shapes parent-offspring conflict by* offspring having more resources. Offspring should attempt to gain more from parent than parent will attempt to give but parents will "punish" greedy offspring

Describe your favorite amazing flying story that was discussed in class.

Small songbird tracking - first time able to track small songbirds (wood thrushes and purple martins) - too small for satellite transmitters so fit them with a geolocator which records the sunrise and sunset every day. - They travel more than 300 miles/day - made it from Brazil to Penn. in only 13 days (b/4 this we thought it took them a month); takes them 45 days to go south for the winter; differences may be because the earliest returning birds get the best territories Frigatebird - nonstop journey of over 2500 miles round trip to get food for her chick - departed Oct 18th and didn't return until Nov 18th Bar-tailed godwits - 6 to 7 days to cover the route, flying up to 2km high at an average speed of 56 km/h (see slide for details of path) - When the godwits set out from New Zealand they are clinically obese, but they lose about half their body weight in each leg of the migration. - refuel for up to a month before heading out to the last leg of the journey to Alaska - nonstop 11,700km flight on return to New Zealand accomplished in about a week!

Epigenetics of stress response in Norway rats

Some Norway rat mothers nurture young more than other mothers: -Pups of nurturing mothers tolerate stress better than pups of neglectful mothers -stress tolerance a function of glucacorticoid hormones -effects of glucocarticoids -Mobilization of glucose for use in crisis -suppression of immune antiflammatory response Contact between mother and pup increases levels of expression of glucocorticoid receptor gene in pup's hippocampus More glucocorticoids are bound, lowering stress level response Pups are consequently less fearful

Describe the stages of song development in birds that show age‐limited learning.

Songbirds listen to the songs of other individual birds and practice them in stages. 1) the sensory acquisition phase in which hearing song models is paramount -Critical learning period:early period during which information is stored for use in later stages of learning. -memorize song phrases from 10-50 days old for White-crowned sparrows Silent phase. Bird stores syllables that it memorized during the critical learning period without practicing 2) the Sensorimotor phase in which practice is paramount Subsong period: practice period is similar to a baby babbling. Briges gap between perceptual and sensorimotor stages of vocal learning. -Critical period for hatching -150 day juvenile has "subsong"-need to hear song to tweak, lasts a month (white-crowned sparrow) Song crystallization: young bird perfects song and organizing syllables into correct patterns and timing. -at 200 days song is perfect.(white crowned sparrow)

Using the Stars to Navigate

Steve Emlen set up three groups of indigo bunting chicks in the planetarium. Chick reared: 1. In a room with a diffuse light at night. 2. With a normal star map that rotated around the North Star. 3. With an abnormal star map that rotated around Betelguese (a star in the South!). Conclusions 1. Indigo buntings are using the stable point in sky as a reference when migrating. 2. Buntings appear to learn this point as young birds. 3. Data suggest they are learning more than just the star around which night sky is rotating.

The cuckoos mimics eggs of different species across everywhere -egg coloration is w-linked

What do we expect for point transects?

The distribution of objects with respect to distance should increase detentions because the area is bigger -Because there is less area near the center of the circular plot, we expect few objects to be close to the observer, even though detection probability is higher there

Evolution of zoos-early days

The first collections of exotic animals were assembled at around 3000 B.C., the time of the earliest urbanized civilizations. These early collections, within the context of their times, were in effect the earliest zoos, even though they were not then referred to as zoos. Zoo-related terminology, as it now exists, didn't not come into use until the modern zoo concept developed during the 18th and 19th centuries. Ancient Greeks, Romans and Egyptians all had collections of exotic animals. The earliest animal collections were often times private collections of royalty, gardens and aviaries.

Define and examine the idea of trophic cascades. What is the importance of a predator in the ecosystems? Explain from the perspective of someone interested in animal behavior what is likely to occur. Finally, discuss whether a predator is necessary in the system or might a clever, well-trained wildlife behavioral ecologist identify ways to mitigate the absence of a predator?

The trophic cascade is an ecological concept which has stimulated research in many areas of ecology. A top down cascade is a cascade where a top predator is removed and affects everything below the food chain. A bottom up cascade is when a primary producer is removed and there is a reduction of population size through the community. If we were to remove a predator such as a starfish we might think that a different predator would come and dominate. But this does not happen, nothing is controlling the lower species. Without starfish barnacles will do well and take over and take over the open spaces. As a result biodiversity decreases, there is no longer open surfaces for other species. At zion national park there are many old trees and not any young trees. This is due to the absence of cougars in the area. Cougars are deterred by human presence. The deer figured this out and will be hanging around the park and will eat any small trees that do come up. Also, the absence of cougars cause rivers and streams to widen and become shallow. Causing the water to be warmer and increase erosion. Also, with the reintroduction of wolves this can cause deer to spread out more within the environment. But this is not always the case in all systems. Sometimes, no matter the predation risk there will be a lot of browsing going on and eating small trees. There could be many other factors influencing where and how much shrubbery deer will eat. Also, elk don't all respond the same way. There is data that shows that females that have calves are more vigilant and are weary of wolves. Females that don't have calves are not as attentive and responsive. And males go wherever they want to eat because they are big.

The rock-paper-scissors game in side-blotched lizards

There are 3 male morphs in side-blotched lizards. Differences are genetically-based -Orange are ultra dominant, blue guard mates, and yellow mimic females and sneak matings

Why are the three types of male side-blotched lizards said to be involved in a game of rock-paper-scissors.

There are 3 male morphs in side-blotched lizards. Differences are genetically-based -Orange are ultra dominant, blue guard mates, and yellow mimic females and sneak matings. No one strategy will ultimately beat the other two strategies -If one color has a low number of individuals then the females prefer that color type

Three categories of assessment of animal welfare

Three categories of assessment: 1. Biological functions - variables thatindicate normal physiological function High survival, growth, repro; low stress hormones 2. Affective states - variables that indicatelevels of pain or distressLow stereotypy, aversion/avoidance; high play 3.

Robert Trivers

Trivers proposed the theories of reciprocal altruism (1971), parental investment (1972), facultative sex ratio determination (1973), and parent-offspring conflict (1974). He has also contributed by explaining self-deception as an adaptive evolutionary strategy (first described in 1976) and discussing intragenomic conflict.

How do temperate and tropical birds differ in their annual cycles?

Tropical species have larger breeding seasons -"Breed year round" -short period molt -eliminate migration

Do tropical species live longer? How do tropical territories work?

Tropical species live longer. Offspring will stay in parents territories until there is vacancy

What are two approaches to estimate abundance of closed populations

Two approaches to estimate abundance of closed populations: 1. capture, mark, then return individuals to the population = *capture- recapture methods* 2. capture and remove individuals from the population = *removal methods*

Estimating species richness

Two common strategies when surveys are imperfect and detection probability <1. 1. Species‐accumulation (rarefaction) curves 2. Capture‐recapture sampling

Occupancy sites with no detections represent

Two possible "states" that we cannot distinguish 1) Site is truly unoccupied 2) Site is occupied, the the species was never detected If surveys imperfect p<1, classifying sites with no detections as unoccupied will underestimate true occupancy because some proportion of sites are likely to be occupied even though the species was never detected

Home Range methods

Two ways to estimate size of home range methods *Minimum Convex* -Polygons (MCP) -over estimates of home ranges -Advantage: large areas to find potential ranges for conservation projects *Kernel methods* -based on the likelihood of finding animals -underestimates of home range -Advantage: easier to site id, more defined areas

Variance of standard variation

Pecton

Vascular dark material in eye.(amount of folds and location depends on taxa) Nourishes eyes. no blood vessels in retina all in PECTEN. - Acute vision, more vision, more efficient. - Know funtion at the most basic level. - Hypothesis: reduce glare, navigational function, dark mirror (see things close to sun), and regulate eye temp. and hydrostatic pressure. Other reasons for pectons possibly: -Reduce glare -Navigation function -Dark mirror for viewing objects close to sun -regulate eye temperature and hydrostatic pressure -We have blood vessiles in Rectina, birds don't and its in pecton.

Solitary

Vast majority of mammals. Solitary except for mating and rearing young.

Concurrent exchange

Veins in a bird's artery within the legs, run along each other. The SHUNT opens in the foot and bypasses a lot of the cold, this allows them to transfer heat throughout the foot. SHUNT is "closed" to limit the spread of blood since it will take more energy.

Channel depth

Vertical height of the water column from the water surface to the channel botton -measured as the average of depths taken at three locations, 1/4, 1/2, 3/4 across the width

What are three cues / mechanisms that birds use to navigate? For each cue, describe a study that demonstrated its importance in avian navigation.

Visibility of setting sun On sunny days, pigeons wearing magnets and control pigeons with brass bars both went to the correct location. When there was an overcast, the pigeons wearing the magnets were disoriented. The control group showed they used earth magnetic information. Visibility of stars Indigo Bunting migrate at night showed restlessness when confined to funnel cage placed under planetarium sky. Inky foot prints recorded the orientation direction. When the planetarium shifted so the north became the south, the birds reversed their orientation. When the stars were turned "off" they did not orient. Magnetic cues By attaching Helmholtz coils to the heads of homing pigeons, it generated artificial magnetic fields by allowing an electric current to flow through the coils. The reversal of the electric current, which reversed the magnetic field, caused the pigeons to reverse their orientation direction on overcast days.

Selecting a model

We use models to represent and unknown truth, so the most appropriate model will depend on the data available -Small data sets cannot support complicated models Goals of model selection: find a model that fits the data well and does not have more than the number of parameters that can be supported given the data (= a parsimonious model) Avoid: -Overfitting( too many parameters) -Underfitting(too few parameters)

Prisoner's Dilema

What happens when you and a buddy are taken by the police? They usually they separate them and hoping them to get one buddy to confess. If they have enough information and both decide to stay silent they might get something from the police (fine, sentenced). One buddy could also remain silent forever while the other buddy confesses. Both can confess as well and both can go to jail for some period of time. The least "nasty" outcome, both remain silent. -Simple Rule: Don't say anything (most efficient) -The same rules apply to animals and how they decide on certain topics. (whether they're going to move to find new mates, etc. )

Define and examine the different types of mating systems observed in wildlife species and detail what vertebrate taxa in which they are most common.

Within wildlife species there are six different types of mating systems that can be observed this includes monogamy, polygamy, polyandry, polygyny, polygynandry, and promiscuity. *Monogamy* is when there is one male and one female present that mate with each other and there are two types, serial or lifelong. Serial is when a mate has different partners in different breeding seasons while lifelong is when they have a single mate for life. This is seen in a <3% mammals, including wolves, prairie voles, monkeys, and white footed deer mice, but is mainly seen in >90% of birds, but this is behaviorally, as monogamous couples have 60% chance of experiencing extra pair copulations *Polygamy* involves three different types, polygyny, polyandry, and polygynandry. Polygamy is when one sex mates with more than one mate. When a female is seen to have more than one mate this is called *polyandry* and can be seen in 1% of birds and <1% of mammals. Examples of polyandry are lilly trotters, sandpipers, Goelde's Marmoset and Haris Hawks. *Polygyny* is when males have more than one mate and is seen in 2% of birds and 35% in mammals. Examples of mammals include elk (38%), pronghorn, white tailed deer, coyote, red fox, and wild turkey. There is three types which include resource defense, mate defense, and male dominance. *Polygynandry* is when females and males have more than one mate, but are exclusive and this is seen in 1% of birds and less than 1% of mammals (acorn woodpecker, bonobos, foxes). Lastly, is promiscuity which is when both sexes have more than one mate and can be seen in 6% of birds and 60% in mammals.

Do the sexes differ with respect to mate competition and mate choice?

YES -males compete more intensely for mates than do females and females are choosier about their mates than are males

Do genes encode behavior?

Yes! In Drosophila, males "sing" to females. CAC mutants sing poorly and shout.

Does genetic variation play a role in evolution by natural selection?

Yes. Evolution can only occur if there is genetic variation in a trait

Can a gene have more than 1 effect? Drosophila example

Yes. Example: The period mutant in Drosophila Per affects: -Time of day that pupa becomes adult -Daily activity rhythm -Male courtship rhythm

Adaptive Radiation

a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches.

Speciation in birds typically includes 3 stages:

a) colonization of a new environment, b) population subdivision and geographic isolation, c) divergence due to sexual selection, ecological selection, and accumulation of genetic incompatibilities (i.e. allopatric speciation). Speciation can happen in sympatry but this scenario is apparently rare.

Why do birds eat chili peppers that mammals avoid? What are the benefits to the plant of birds eating their fruit?

chili plants have high capsaicin to deterre mammals and attract birds for dispersal - chili seeds get less damaged when dispersed by birds - seeds grow better from being dispersed by birds after they were eaten - birds also eat insects that harm the chili plant, so it grows better.

What is anisogamy? What is one explanation for its evolution? What implications does anisogamy have for the pattern of mate competition, mate choice and parental care in animals?

involves gametes that differ in size & structure Evolution :Selection should favor: 1. gametes effective at fertilizing other gametes. 2. gametes, once fertilized, better at developing to adulthood. *No one gamete can be good at both.Selection favors gametes that are one or the other* 1. Males make many, many sperm, each of low investment. 2. Females make a small number of eggs, each of high investment Consequence 1. Male fitness will be limited by number of mates. 2. Female fitness will be limited by quality of mate Implications Given the difference in what limits fitness: females should be choosier about who they mate with, and males should compete more for mates than do females Because females invest so much in the gamete, they should invest more in offspring care. Pattern: Females generally do invest more in parental care
