Seminar exam 2
why are monoculture ecosystems not helpful in concervation
lack of biodiversity
Why does Myotis Septentrionalis not have any subspecies classified...yet?
large genetic diversity which leads to no genetic variation in groups from different geographic regions
What is the greatest threat to the California condor?
lead found in carcasses of dead animals
what was used un the study to determine if traplines were active and why was it used?
American marten fur was used because of the furbearer rates of this animal were consistent ( made sure the trappers were active within the sampling unit)
The Iberian lynx is endemic to: Greece Portugal Spain Italy B & C
B & C
why is it important to save the California condor?
It helps clean up nature by being a carrion bird. They reduce disease by ingesting dead animals which are disease vectors
What was the major difference between major and minor injuries in whale sharks?
major injuries affected the shark in a threatening manner that could cause death or impairment to the shark's fitness. Minor injuries were mostly cosmetic and did not alter the shark's fitness
what is the predominant determining feature between the black rhino and white rhino?
mouth/lip shape; black rhino has pointed upper lip
soft release improved the bonding of African wild dogs. what is soft release
moving dogs into a separate, smaller area before fully releasing them into the park
what are some suitable breeding substrates other than grain fields for the tricolored blackbird?
nettle or cattails
How often do California condors have babies
one chick every other year
What is the defining characteristic of pangolin
only scaled mammal
what has been the biggest threat to the pangolin?
overharvesting/poaching
what is the major threat to the eastern black rhino
poaching for their horns, Chinese medicine, ornamental use, and big deal with illegal trade
What is the primary food source of the black footed ferret and how has it played a role in its endangerment?
prairie dog and accounts for 90% of its diet. There is a linear relationship between prairie dog population and black footed ferret
Which risk of endangerment has the highest severity and impact
WNS and habitat loss
what was the wild dogs favorite prey to eat?
Warthog and wildebeest?
what is the main prey of the Canadian lynx
snowshoe hair
what was the reason African wild dogs went extinct in the Gorongosa national park in the past
civil war
what is unique about the California condor's head?
doesn't have feathers which help it stay clean and the pinkish color that changes depending on its mood
how often does the black rhino reproduce
every two and a half to five years
what organisms make up the Chinese pangolin's diet
exclusively some ant and termite species
t/f African wild dogs are mainly found in north Africa today
false, mainly found in south africa
t/f low adaptability to new habitats, potential inbreeding, and low genetic diversity makes the Iberian lynx less susceptible to infections
false; makes them more susceptible
By what method are whale sharks feed by
filter feeding
what is the main threat of existence to the tricolored blackbird?
habitat destruction during breeding season
what is the technique known and furbearer harvest
harvests the fur of specific species within a certain range or area that can help monitor and study the change in range/population dynamics of a species
What is the main prey of the Iberian lynx
European rabbit
name one of the conservation efforts used to help the NLEB species
Research on WNS, feathering turbine blades, typical conservation efforts to help climate change, and hibernacula protection (buffer zones)
what was bycatch
accidental capture of whale sharks/ unintended species in fishing gear
select the threat that affects the depopulation of the iberian lynx: viral infections microsporidia habitat fragmentation road kill all above
all above
what are other species causing an increase in competitive potential among the Canadian lynx
bobcats and cyotes
which state holds 95% of the tricolored blackbird population?
california
list two conservation actions for the eastern black rhinos
captive breeding conservation, in-place research and monitoring
what are two of the health issues associated with pangolins in captivity?
capture myopathy, pneumonia, ulcers, GI issues, and/or heart attacks
How does WNS affect the northern long eared bat?
causes an increased energy demand during hibernation which depletes their fat reserves and makes them weaker when waking up
what are some predicted factors that may be contributing to the decrease of the Canadian lynx
high human disturbance, shallow snow, climate change, and increase in competitors
why are the grain fields so dangerous for the tricolored blackbirds, especially their young?
if farmers harvest their crops before the young have time to fledge, they will not survive
What was done to try and protect the black footed ferrets from the plague
insecticide to slow spread by killing fleas and vaccinating prairie dogs/black footed ferrets
what is one of the main threats to the black footed ferrets
sylvatic plague
Why were other species of bats in the WV WNS study positively impacted by the WNS?
taking advantage of loss of smaller species of bats and rapid evolution of resistance genes
what is the California condors nickname?
thunderbird
t/f The lowest population of the Iberian lynx ever recorded was below 100 individuals
true
t/f did the article fine that there were four generas that were significantly associated with breeding success
true
t/f the tricolored blackbird is the most colonially extant bird in the US
true
t/f there was an association between residency and major injury with the whale sharks that were studied.
true
What was the suggestion on the conservation of this species in the south Ari Atoll marine protected area?
vessel traffic reductuion
what did researchers call a wild dog pup that was at least twelve months old
yearlings
