Which of the following statements is/are consistent with the Intermediate disturbance hypothesis? Species diversity is maximized in areas that experience high levels of disturbance Areas with low levels of disturbance will be dominated by K selected species Decades of suppression in California has likely increased diversity in our national forests Areas with intermediate levels of disturbance will have the lowest levels of diversity

Which of the following patterns best describes how species richness changes from the arctic to the tropics? Species richness increases from the arctic to the tropics O Species richness remains the same from the acrtic to the tropics Species richness decreases from the arctic to the tropics Species richness increases, then decreases from the arctic to the tropics O None of these
The figure below shows the relative abundance (y axis) of shrubs in an ecosystem in the years following a fire (x axis). The shrubs in this ecosystem fall into two functional groups: fıre recruiters and fıre persisters. FIRE-RECRUITER SYNDROME FIRE-PERSISTER SYNDROME 10 100 Fire LOG YEARS If fire frequency decreased significantly in this ecosystem, which group would be benefited? O Both functional groups would benefit equally O Fire recruiter species O Fire persister species RELATIVE SHRUB SEEDLING ESTABLISHMENT
Predation, disease, and competition are examples of _______________ factors. (a) density-dependent (b) density-independent (c) survivorship (d) dispersal (e) semelparous
The _______________ signifies that species richness is greater where two communities meet than at the center of either community. (a) edge effect (b) fundamental niche (c) character displacement (d) realized niche (e) limiting resource
A rain forest habitat is located in an equatorial area with a warm, wet climate. Nearby is a savanna, where the climate is equally warm but much drier. Species diversity is much higher in the rain forest. Which rain forest habitat characteristic most likely explains this difference? O More disturbances, leading to rapid species turnover O More complex habitat structure, enabling greater food availability O More complex habitat structure, enabling greater niche specialization O Fewer disturbances, leading to rapid population growth of a few species O Fewer open spaces, leading to inability of organisms to leave the habitat
Species in Two Communities Community 1 Community 2 E E E E £ Which statement best describes these two communities in terms of species richness, relative abundance, and biodiversity? о о O Both communities have the same species richness; however, community 2 has a higher relative abundance in all but one species and community 2 also has greater biodiversity than community 1. Community 1 has a dominant species, but has the same species richness, relative abundance, and species diversity as community 2. Both communities have the same species richness and biodiversity; however, community 1 has a higher relative abundance in all but one species when compared to community 1. Community 2 has a higher species richness, relative abundance, and species diversity when compared to community 1. EEEE EEEEE EEEE
Bighorn sheep are an iconic species in the western United States, however, their population size is drastically lower than it once was historically. These sheep inhabit montane patches surrounded by urban and agricultural landscapes. Accordingly, bighorn sheep can be considered a metapopulation. Wildlife managers would like to increase the patch occupancy of bighorn sheep. Which of the following would be the most effective conservation/restoration strategy? None of these statements is an effective conservation strategy. O Increase patch size and quality, and decrease the distance between patches. O Increase patch size and the distance between patches, and decrease patch quality. O Increase the distance between patches and patchy quality, and decrease patch size. Decrease patch size, distance between patches, and patch quality.
Which of the following is not a part of the red list criteria for "critically endangered" species? The population is expected to decline by 25% or more within 3 years or 1 generation. The species has a restricted range <100km2 at a single location and there is observed or predictive habitat loss, fragmentation, ecological imbalance or heavy commercial pollution. Extinction probably is greater than 50% within 10 years or 3 generations. The total population size is less than 200 mature individuals.
CA least tern ENDANGERED ANIMAL is CA least tern questionbases on the bird CA least term Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?
1) Which of the following defines the niche of a species? The role of a species in its community as well as the conditions it requires and the interactions it takes part in All populations of all species in some area The type of environment in which a species lives The number of species and their relative abundance within a community 2) Which of the following is an example of a biological factor that can affect community structure? Tropical regions support a high species diversity by receiving the most sunlight energy. The high temperatures of desert regions limit which species can live there. A plant species can live only in regions with a suitable level of rainfall. An insect herbivore inhibits the population growth of a tree species. 3)Which of the following prey defensive adaptations involves two or more prey species coming to resemble one another? Camouflage Startle displays…
