The elimination of predators by humans
a. will cause its prey to experience exponential growth until new predators arrive or evolve.
b. will lead to an increase in the carrying capacity of the environment.
c. may increase the population size of a prey species if that prey’s population was being regulated by predation from the predator.
d. will lead to an Allee effect.
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.
Which of the following strategies would most rapidly increasethe genetic diversity of a population in an extinction vortex?(A) Establish a reserve that protects the population’s habitat.(B) Introduce new individuals transported from other populations of the same species.(C) Sterilize the least fit individuals in the population.(D) Control populations of the endangered population’spredators and competitors.

- Which statement is a valid analysis about bison movement and the carrying capacity of Yellowstone National Park? A. The decrease in the northern herd's population is explained by its inability to migrate and the park's decreasing carrying capacity. B. The fact that bison only migrate in years of deep snow indicates that they have exceeded the park's carrying capacity. C. The carrying capacity for other animals found in Yellowstone has increased due to the bison's migration outside of the park. D. The movement of bison beyond park boundaries is not due to the bison population being too large for the park's carrying capacity. Part B: Which selection from the text provides evidence that directly supports this analysis? A. They move to lower elevation ranges during the winter months in response to snow accumulation and snowpack development. B. The model integrates data from several ecosystem-related variables,…arrow_forwardWhen populations are drastically reduced in size, genetic diversity and heterozygosity a. are likely to increase, enhancing the probability of extinction. b. are likely to decrease, enhancing the probability of extinction. c. are usually not factors that influence the probability of extinction. d. automatically respond in a way that protects populations from future changes.arrow_forwardRabbits are important grazers, maintaining some important grassland habitats.

- Which 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_forwardThe Burmese Python, an invasive species, has been introduced to the Florida Everglades, largely through release by owners who acquired the snakes from exotic pet traders. Though the Everglades are protected, pythons as predators can not be easily controlled. What can be concluded about the effect of the python population on the biodiversity of the Everglades? A. Since the Everglades are protected, python control is limited under laws that protect species in the Everglades. B. Since the python population is growing, it will eventually become a native species and will increase biodiversity. C. Since pythons prey on many species in the Everglades, resources will be more available for surviving species and fewer will be considered endangered. D. Since pythons have no predators, they are responsible for decreasing mammal population and are a greater threat to biodiversity.arrow_forwardSelective pressures are those aspects of the environment that determine whether a gene mutation is helpful, what contributes to the selective pressure that determines the fur color of rock pocket mice Group of answer choices A.
