Chapter 20, Problem 7MCQ
Summary Introduction
Introduction:
A captive breeding program captures adults from the wild and allows their reproduction in captivity. The young ones are nurtured and protected until they are mature enough to return to their native habitat.

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

- The 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_forwardWhich activity would be most likely categorized as restoration ecology? a.

Group of answer choices A) low; the best competitors exclude any other species B) high; disturbances kill off a large number of individuals C) low; there are fewer late-successional species than early-successional species D) high; more species can colonize over a longer period of time Question: Answer choice selection is either: Burkina Faso or Italy for all three answer choicesarrow_forward
- 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.arrow_forwardThank you for your help Describe how a researcher would determine the size of a penguin population in Antarctica using the mark and release method.

It is experiencing logistic growth because the rate of population growth increases without slowing. B. It is experiencing logistic growth because the rate of population growth increases but slows with time. C. It is experiencing exponential growth because the rate of population growth increases without slowing. D. It is experiencing exponential growth because the rate of population growth increases but slows with time.arrow_forwardIf 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.arrow_forward
