Question
Chapter 16.2, Problem 4TC
Summary Introduction
To explain:
The about the necessity of small areas that must be linked by corridors of appropriate habitat.
Introduction:
The main threat for the endangered species is habitat destruction. The circumstances are responsible for the preservation of a large, unbroken area of a threatened species habitat. According to biologists, the small areas can be protected and they are linked by corridors of the appropriate habitat.

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.
In the Rocky Mountains, valley bottoms provide a high quality wildlife habitat and offer a way for wildlife to move through the mountain environment. However, valleys are also important to humans, as most human activity in the Rockies is confined to the valley bottoms. This results in competition for space between wildlife and humans, which poses a significant problem for both.
A wildlife corridor is an area of habitat that connects wildlife populations that are separated by human activities or structures such as roads or development. How do wildlife corridors increase gene flow and maintain diversity in populations?
Examples of ecological restoration include all of the following EXCEPT:
- building levees to minimize the water that enters a floodplain.
- eliminating invasive species.
- replanting a forest.
- removing a dam.
- using periodic, controlled burns to promote native prairie plants in an abandoned farm field.

Which of the following problems would you focus on first and why: habitat destruction and fragmentation, hunting and fishing activity, harvesting of wild species for commercial sale, or introduction of exotic organisms?arrow_forwardBob Davison describes the Endangered Species Act (ESA) as an effective tool for conserving biological diversity. What is his rationale for the value of focusing on individual species? The public is not concerned about the economic costs of individual species recovery. A focus on individual species is cheaper than protecting entire ecosystems. Establishing public empathy for charismatic species provides an opportunity to educate people about lesser-known species. The public tends to value intact ecosystems over particular plant and animal species.arrow_forward
- The Canary Islands are a volcanic island chain off the western coast of Africa with a larger percentage of specialist species than generalist species. If an invasive species is introduced to one of the Canary Islands, which of the following represents an immediate impact? (NOTE: a specialist species has a narrow ecological tolerance, while a generalist has a wide ecological tolerance) The populations of the invasive species on the Canary Islands will decrease as predation increases. The population of the invasive species on the Canary Islands will decrease because they were outcompeted by native specialist species. The populations of both the invasive species and the specialist species on the Canary Islands will remain the same as a result of resource partitioning. The populations of the specialist species on the Canary Islands will decrease as competition for resources increases.arrow_forwardIf you are one of the environmentalists and was assigned in one of the forests in the Philippines which happened to be the location of some endangered species, what are the plans that you would organize to ensure the conservation of the species of the flora and fauna present in your assigned area?arrow_forwardWhich one of these statements about COSEWIC is false? COSEWIC's assessments take into account political, social and economic factors. The Species at Risk Act (2002) established COSEWIC as an advisory body.

Members of COSEWIC are wildlife biology experts from academia, government, non-governmental organizations and the private sector responsible for designating wildlife species in danger of disappearing from Canada.arrow_forward
