- slands are well known for having many endemic (unique) species. What is a likely explanation for this pattern? A. Humans bring partly or fully domesticated species with them when they arrive on islands. B. Colonizers encounter fewer competitors on an island, so they can diversify. C. Islands are more complex habitats than continents are, so they have more niches for specializations. D. Colonizers are likely to have more diversity than local populations and thus outcompete them. E. 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.arrow_forwardWhich of the following is not true of a population of largepredators in a small reserve?a. The species may disappear from the reserve.b. The species will probably undergo a populationexplosion.c. The species will probably lose genetic diversity.d. The species may overeat its prey, causing a reduction inprey population.arrow_forwardEcological dominants are a. the most numerous or make up the most biomass within a community. b. are species that may not be the most numerous within a community, but whose role is so significant that its absence would bring about considerable change. c. species that are introduced into an area where they do not naturally occur. d. the most important species on the planet.arrow_forward
- The American Bison was hunted to near extinction by early settlers. Which answer is correct about the current population of American Bison? chose the correct answer(s) a.It has experienced a population bottleneck. b.It is more genetically diverse. c.It has experienced the founder effect. d.Both a. and b. e.Both b. and c.arrow_forwardAccording to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out.All of the following are consistent with the principle of competitive exclusion EXCEPT Select one: a. Birds and bats both consume flying insects, but birds are active in the day and bats are active at night. b. Two species that share the same niche will exclude other competing species. c. Different bird species forage for insects in different parts of the same tree. d. When two species of Paramecium are grown in the same medium, one strain will eventually eliminate its competitor.arrow_forwardThe 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 samearrow_forward
- In populations subjected to high levels of predation a. individuals should invest little in reproduction so as to maximize their survival. b. individuals should produce few offspring and invest little in any of them. c. individuals should invest greatly in reproduction because their chance of surviving to another breeding season is low. d. individuals should stop reproducing altogether.arrow_forwardArguments in favor of the overkill hypothesis of megafauna extinctions are a. Basically everywhere humans colonized, big animals went extinct b. Climate change similar to the end of the Pleistocene happened many times before, and there was no megafauna extinction c. In nearly all the Clovis kill sites in North America, mammoth or other megafauna are present d. All of the abovearrow_forwardSpatial scales are interconnected in a hierarchical way. Whitman looked at invertebrate communities on subtidal rock walls to examine the relationship between local and regional species richness. His studies demonstrated that A. local, not regional, processes determine local community species diversity B. local species richness levels off at high regional species richness levels C. local species richness is determined largely, but not completely, by regional species pools D. local processes are unimportant in determine local community species diversity E. There was no relationship between local and regional species richnessarrow_forward
