Why are species that live at the tops of mountains at increased risk of extinction due to climate change? a. The colder temperatures at the tops of mountains gradually increase, and the species at the tops of the mountains are displaced by species at lower elevations moving up. b. The species at the tops of the mountains are adapted to moving up and down the mountains and species at lower elevations are displacing them as they move down the mountains. c. The species at the tops of the mountains are adapted to lower oxygen and climate change increases oxygen content in the air. d. Species at the tops of mountains do not have the genetic diversity for adaptation that lower-elevational species do. Therefore species at the tops of the mountains are more likely to go extinct.

Which statement about zero population growth isoclines of two competing species is true? A. Species coexistence requires that the two isoclines cross. B. The crossing of the two isoclines is a sufficient condition for species coexistence. C. If the species coexist, they will each do so at a higher density than either would if placed alone. D. Strongly competing species can only coexist if the two species have very different carrying capacities. E. Coexistence will occur if the two isoclines are parallel.
Which statement comparing island biogeography to mainland biogeography is true? A. The slope of species richness to area should be steeper for mainland species than for island species. B. Mainland sites should experience higher rates of immigration than island sites. Mainland sites should experience higher rates of extinction than island sites. C. D. On the mainland, extinction rate increases with area faster than immigration rate does, whereas the opposite is true for islands. E. Extinction rates would be the same for mainland and island sites.
Islands are well known for having many endemic (unique) species. What is a likely explanation for this pattern? O A. The type of organism that is a good colonizer has more than the average amount of genetic variability, so it's more likely to speciate. O B. Colonizers encounter fewer competitors on an island, so they can diversify. O C. Islands are more complex habitats than continents are, so they have more niches for specializations. O D. Humans bring partly or fully domesticated species with them when they arrive on islands. O E. Colonizers are likely to have more diversity than local populations and thus outcompete them. «< Question A Moving to another question will save this response.

Give typing answer with explanation and conclusion A conservationist wants to enhance survival of individual Daphnia populations in the metapopulation along the Scandinavian coast. To be successful, which action would this conservationist most likely carry out in these freshwater rock pools? a. Connecting vulnerable pools by making dispersal corridors to the ocean b.Separating the smallest pools from the largest to prevent immigration c.Removing the shortest-lived Daphnia species from all pools d.Separating pools so the Daphnia cannot mix with one another e.Connecting vulnerable pools by making dispersal corridors between them

hichstatement about snowshoe hare and lynx populations in boreal Canada is false?a.Lynx are not the only important predator of snowshoe hares.b.Lynx and hare populations both oscillate repeatedly, with a similar period.c.Snowshoe hares rarely deplete their food supply enough to affect theirpopulation biology.d.Trapping records kept by non-scientists can provide useful records ofhare population sizes.e.Field experiments imply that hare cycles depend both on the hares’ foodand their predators.
The number of species on an island depends on the size of the island and its distance from a mainland. This statement would most likely be made by . a. an explorer c. a geologist b. a biogeographer d. a philosopher
The long-leaf pine forest ecosystem once extended across 95 million acres of the southeastern US. However only 5 million acres now remain causing major declines in the Gopher tortoise population. Given this, what is expected to happen to overall diversity of species that depend on Gopher Tortoise burrows?a. increaseb. decreasec. stay the same
A species which are facing extremely high risk of extinction in immediate future is called as?
If populations of white rhinoceros (Ceratotherium simum) continue to decline, one approach to prevent extinction would be captive breeding. How does this process work? a. The remaining animals are moved into captivity to try to increase the population, after which they are reintroduced into the wild. b. The remaining animals are moved to a national park. c. The remaining animals are taken to the largest zoos so more people can see theam. d. A few individuals are moved to an outdoor enclosure to ensure that mates are available.
How is a clumped population distribution beneficial for prey animals? a. Being a member of a larger group provides protection for each individual from predators. b. Prey animals rely on each other to acquire food. c. Prey animals live in small family groups to raise young. d. Clumped population distributions ensure that at least one member of the population knows how to identify the seasonal migration route.
What factors influence gene flow between populations?A. The home range size of the species.B. Differences in animal behavior and life history strategies can form effective barriers to gene flow.C. Barriers to gene flow between populations are always physical geographic barriers.D. Reproductive barriers must involved anatomical differences that prevent mating.
