Pbio exam 3
Summarize the goals or functions of biosphere reserves. Analyze how well these goals address the needs of local and global communities.
-Focusing on a multi-stakeholder approach with particular emphasis on the involvement of local communities in management -Acting as sites of excellence for education and training -Promote dialogue for conflict resolution of natural resource use
Discuss the other types of activities that are needed to meet related conservation activities. Explain why plants of socioeconomic importance or their wild relatives merit conservation.
-Maintenance of associated indigenous and local knowledge. Explain why plants of socioeconomic importance or their wild relatives are awarded conservation: genetic diversity of minor crops and other socio-economically important species have received less attention. Priority species may include certain medicinal plants, non-timber forest products, local landraces, wild relatives of crops, neglected and underutilized plant resources as well as major forage and tree species, which may become the crops of the future.
Describe the zones that are established for biosphere reserves, indicating which has the highest level of protection
-The core area is strictly protected ecosystem that contributes to the conservation of landscapes, ecosystems, species and genetic variation. -The buffer zone surrounds or joins the core areas, and is used for activities compatible with sound ecological practices that can support scientific research, monitoring, training and education. -The transition area is the part of the reserve where the greatest activity is allowed, encouraging economic and human development that is socio-culturally and ecologically sustainable. Analyze how well these goals address the needs of local and global communities: -the core area brings ecosystem services which can be calculated in economic terms (carbon sequestration, soil stabilization, supply of clean water and air). Employment opportunities can also complement conservation goals (environmental education, research, environmental rehabilitation and conservation measures, recreation and ecotourism). -the buffering zone brings biological and cultural diversity. They can also have an important connectivity function in a larger space context as they connect biodiversity components within core areas with those in transition areas. -the transition area may contain a variety of agricultural activities. local communities, management agencies, scientists, non-governmental organizations, cultural groups, economic interests and other stakeholders work together to manage and develop the area's resources

Name the five factors that are considered before a species is listed
1) damage to, or destruction of, a species' habitat; 2) overutilization of the species for commercial, recreational, scientific, or educational purposes; 3) disease or Bart Gamett/USFWS predation; 4) inadequacy of existing protection; and 5) other natural or manmade factors that affect the continued existence of the species. When one or more of these factors imperils the survival of a species, the FWS takes action to protect it. The Fish and Wildlife Service is required to base its listing decisions on the best scientific information available

Distinguish between direct and indirect effects of invasive plant species on ecosystem
A direct effect of invasive species have to do with an exact pinpointed problem caused by invasive species. For example, the american chestnut was victim of an invasive species, and the direct effect is the loss of chestnuts in forests. An indirect cause would be wildlife that eat the food will be penalized too.

Explain how an important plant area (IPA) is defined and what impact these defined areas have on conservation.
An important plant area can be defined as a site exhibiting exceptional botanical richness and/or supporting an outstanding assemblage of rare, threatened and/or endemic plant species and/or vegetation of high botanical value. ~Countries make significant efforts to protect these areas but it is often not followed through with or low scale management plans
effects on property values of Asian longhorned beetles and Emerald ash borer
Asian longhorned beetles first appeared in NY in 1996 and in Chicago in 1998. Larvae go into trees causing girdling (removal of bark) of stems and branches, dieback (death of twigs and branches which generally starts at the tips) of the crown, and can kill an entire tree. It infests many different tree species in the U.S. and is a threat to urban and rural forests. Emerald ash borers were first detected in the U.S. in 2002, found in Michigan, Ohio, and Indiana, larvae tunnel under bark of ash trees and could eliminate ash as a street, shade, and forest tree throughout the U.S. Estimated replacement cost in six Michigan counties is $11 billion and an additional $2 million in lost nursery sales.

Name the differences among species that lead to variability in responses to climate change and describe how this might affect interspecific relationships.
Species differ in their physiological tolerances, life-history strategies, probabilities of population extinctions and colonizations, and dispersal abilities. These individualistic traits likely underlie the high variability in strength of climate response across wild species, even among those subjected to similar climatic trends. The primary impact of climate change may be mediated through effects on synchrony with that species' food and habitat resources
Distinguish between strict protection and mixed-use protection in parks or conservation areas. Discuss the conflicting research results over which is most effective at preventing deforestation
Strict protection: strict protected areas can create counterproductive conflicts between regulators and local communities Mixed-use protection: seeks to strengthen local communities' capacities and incentives for forest conservation -Several studies conclude that strict protection outperforms mixed-use protection -mixed-use protection generally does a better job of stemming forest fires -Strict protection is more effective at preventing deforestation
effects of hydrilla on ecosystems and recreational opportunities
The aquatic plant Hydrilla, form dense canopies at water surface and raise temperatures, change pH, exclude light, and consume oxygen, resulting in native plant displacement and stunted fish populations. This example of an altered aquatic ecosystem caused by an invasive aquatic weed also negatively affects recreation and businesses that depend upon that human activity.
Predict how biodiversity losses could lead to the endangerment or extinctions of species
The loss of biodiversity may take away plants/animals used as food for other species
Describe the migration of plants on the Chimborazo volcano in Ecuador. Name the date and source of the earliest and most recent data sets on plant distribution and vegetation zones
The plants on the highest mountain in Ecuador have migrated more than 500 meters to higher altitudes during the last two centuries. This is determined in a new study, in which researchers compared Humboldt's/ Aarhus University data from 1802 with current conditions. Most recent: summer 2012, The individual plant species are now found more than 500 meters upslope than they were 210 years ago. These changes in the vegetation are more than expected as a result of today's warmer climate
Describe what the general changes in phenology have been relative to leafing out, flowering, production of fruit and growing season. State how this correlates with climate
This is partly a result of the tight links between the seasons and agriculture: Planting and harvest dates (and associated climatic events such as day of last frost) have been well recorded, dating back hundreds of years for some crops
Describe the current rates of species extinctions. Name the causes now and projected for future losses
Today, current extinction rates are estimated to be 100 to 1,000 times faster than those in geological times. 3,481 species out of the 30,700 estimated described species are endangered, and nearly a quarter (22%) of the world's mammal species and a third (32%) of amphibian species are known to be globally threatened or extinct. Causes: globalization caused a few species to dominate, spread of invasive species, reduced global genetic diversity. such losses reduce the fitness and adaptive potential of both species and ecosystems, thus limiting the prospects for recovery after possible disturbance

US$2 to US$6.6 trillion. e total is just 1-4% of the net value
direct and indirect effects of white pine blister rust on natural resources.
White pine blister rust is a disease of white pine species caused by the non-native fungal pathogen starting in 1900. It spread rapidly, killing off native white, whitebark, and limber pines, whose seeds are an important food source for birds, rodents and bears. Also, it alters forest ecosystems, eliminates wildlife forage, and decreases the soil stabilization effects of these trees, snowmelt regulation, and forest succession

Describe the types of records we have that help us understand how phenology of some plants has changed since 1900
a statistically significant change point is first seen in the early 1900s, with steady advancement since 1952
Discuss how changes to the habitat of the yellow-bellied sapsucker will impact other species.
as some tree species will expand their geographic range and others will decrease their range, so too will the different species of woodpeckers. For example, the model predicted that the red-headed woodpecker, Melanerpes erythrocephalus, will increase in abundance throughout the eastern region while the yellow-bellied sapsucker, Sphyrapicus varius, will decrease in abundance. The sapsucker also maintains smaller holes, called "sapwells," from which it eats tree sap for nutrients. This unique behavior creates new food sources and habitats for creatures that live near sapsuckers. The sapwells attract and support various insects, which in turn support other animals. However, models predict greatly reduced abundance of balsam fir trees in the eastern forests due to climate change, and as a consequence, less suitable habitat for the sapsucker.14 Thus, as climate changes affect the distribution of tree species, the animals that depend on these specific trees for food and habitat will be affected as well
Describe what constitutes environmental harm by invasive species
biologically significant decreases in native species populations, alterations to plant and animal communities or to ecological processes that native species and other desirable plants and animals and humans depend on for survival. Environmental harm may be a result of direct effects of invasive species, leading to biologically significant decreases in native species populations
Explain how habitats of endangered species are protected and why they are sometimes exempted from protection
by prohibiting the "take" of listed animals and the interstate or international trade in listed plants and animals, including their parts and products, except under Federal permit. Such permits generally are available for conservation and scientific purposes. Listed plants are not protected from take, although it is illegal to collect or maliciously harm them on Federal land. Protection from commercial trade and the effects of Federal actions do apply for plants. In addition, States may have their own laws restricting activity involving listed species.
intra-specific diversity
diversity within a species (among individuals or populations)
Endangered Species Act (ESA)
he purpose of the ESA is to protect and recover imperiled species and the ecosystems upon which they depend
Define phenology
he study of the timing of an organism's developmental stages, such as breeding or flowering. This is influenced by temperature, amount of sunlight and precipitation.
Explain the purpose of the Svalbard Global Seed Vault and predict how its location makes it an ideal storage facility
holds more than 700,000 seed samples, originating from almost every country in the world. The Vault already holds the most diverse collection of food crop seeds in the world. Deep in the side of a mountain in the Arctic archipelago is the Svalbard Global Seed Vault. Known as the "Doomsday Vault," this seed bank -- operated by the Norwegian government and containing a seed of just about every known crop in the world -- is meant to be humanity's backup in the event of a catastrophe that devastates crops
Name a benefit of in-situ compared to ex-situ conservation
in-situ conservation, the conservation of species in their natural habitats, is considered the most appropriate way of conserving biodiversity.Conserving the areas where populations of species exist naturally is an underlying condition for the conservation of biodiversity. It is more natural within in-situ.
Describe when domesticated or introduced plant species are considered invasive and how this can differ from one area to another.
invasive when they have overcome Geographical barriers, survival barriers, establishment barriers, dispersal and spread barriers.
. Describe natural changes and human activities that have contributed to observed vegetation changes on the Chimborazo volcano.
natural changes and human activities that have contributed to observed vegetation changes on the Chimborazo volcano: Warmer climate, A combination of human induced climate change and the direct impact on the plant communities via cultivation of the landscape around the volcano helps explain the large scale vegetation shift more than has been experienced in other regions outside the tropics

number of species found in an area
Describe examples of conservation activities in production landscapes, such as agriculture and forestry
organic production, integrated pest management, conservation agriculture and on-farm management of plant genetic resources. Similarly, sustainable forest management practices are being more broadly applied
Explain the importance of seed banks in preserving genetic diversity as well as the limitations
seed banks protect biodiversity ~Forsome 200-300 major crops, it is likely that 70% of genetic diversity is already conserved ex situ in gene banks ~limits: do not work on all plant species~ tropical plants
Describe the supporting ecosystem services offered by the Eastern forests and woodlands and how these services are compromised by climate change
soil formation would be lost because of temperature changes (freezing and thawing) ~lower winter temperatures

strategies for the conservation of crop genetic diversity: through ex-situ conservation (seed banks, field genebanks, tissue culture) partly through on-farm conservation and partly through in-situ conservation.
Describe the rate of deforestation occurring in Guatemala and the area protected by the Maya Biosphere Reserve. Name some of the causes behind deforestation in that area
the rate of deforestation in tropical countries remains "alarmingly high." For example, in both Latin America and Africa, it averaged 0.5% per year in the first decade of the 2000s, five times the global rate. Why: rapid deforestation in the past two decades due to immigration and a changing security situation
. Discuss the goals of the Millennium Seed Bank Partnership at Kew

Describe a biosphere reserve. Explain who retains jurisdiction over the reserve
~: areas that include terrestrial, marine and coastal ecosystems. Each reserve helps solutions restore the conservation of biodiversity with its sustainable use ~ biosphere reserves are nominated by national governments and remain under the jurisdiction of the states where they are located
Describe the types of concessions that were established within the Maya Biosphere Reserve and the performance criteria that are expected of all these groups.
~Established resident community concessions (n = 2) were granted to communities inside the multiple-use zone that were settled long before the MBR was established. Historically, these communities have subsisted by harvesting and trading in non timber forest products, such as chicle, xate, and allspice. New resident communities (n = 4) were settled by recent immigrants around the time the MBR was established. Nonresident community concessions (n = 6) were granted to communities outside the multiple-use zone, the result of government efforts to recruit entities to manage concessions. Finally, industrial concessions (n = 2) were granted to commercial timber companies ~criteria include a forest management plan, legal incorporation of the grantee, a democratically elected leadership, and third-party certification to Forest Stewardship Council standards within three years of the granting of a concession
Describe the barriers that invasive species have surmounted and how humans can unintentionally support these invasions
~a geographical barrier must be overcome, which often occurs as a mountain range, ocean, or similar physical barrier to movement of seeds and other reproductive plant parts (plants that do this are often called alien) ~non-native plants are those that occur outside their natural range boundaries, and this most often is mediated by humans either deliberately or unintentionally
Describe ex situ strategies for conservation of genetic resources and discuss their importance
~botanical gardens ~seed bank limitations: do not work on all plant species;/tropical cannot
