Textbook Question
Chapter 27, Problem 2AC
The U.S. Endangered Species Act (ESA) seeks to increase the population of threatened species to the point where they have a self-sustaining population that no longer needs special protection. Research two species that have been listed as endangered: one that has recovered to the extent that it has been "delisted" and one that has remained on the list for more than 20 years. Based on what you have learned in this chapter, what characteristics of the two species and their environment have significantly contributed to their differing fates?

A biologist determines the growth rate of a population of 198 frogs in a marsh near
Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds
that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no
emigration.
a. frogs are considered an indicator species for the quality of the environment. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?
Which 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.
The committee made its first designation in April 1978 and has met annually since then.
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.

Pick the correct following statement number:

2. Releasing wild-collected individuals into a new site
3. Releasing captive-bred individuals into a new site
4. Releasing captive-bred or wild-collected individuals into an ecologically suitable site within their historical ranges where the species no longer occurs

You will use scientific information from a variety of sources and what you learn in each learning cycle to support or challenge the reintroduction of cougars to the Eastern United States. Your position on the issue should be based on evidence related to the following factors: impact that the deer population is having on ecosystems • social and economic costs of the overpopulation of deer on various stakeholders • the habitat requirements of cougars, the availability of natural resources and carrying capacity of areas where they would be introduced • potential cougar impact on biodiversity, including on populations of coyote and white-tailed deer potential social and economic costs or benefits to stakeholders in areas where cougars are introducedarrow_forward
- Which of the following is not a part of the red list criteria for "critically endangered" species? The population is expected to decline by 25% or more within 3 years or 1 generation. The species has a restricted range <100km2 at a single location and there is observed or predictive habitat loss, fragmentation, ecological imbalance or heavy commercial pollution. Extinction probably is greater than 50% within 10 years or 3 generations. The total population size is less than 200 mature individuals.arrow_forwardThe 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_forwardWhat do restocking programs for wild animals involve?

- In a field experiment an ecologist traps 30 mice. She marks all 30 mice and releases them back into her study site. A week later she returns and traps 40 mice. Ten of the 40 mice have been marked representing mice that were captured a second time. What is her objective? To collect data for constructing a mouse survivorship curve. O To estimate the mouse population density using the quadrate method. O To determine if mice who have been previously trapped will avoid being trapped a second time. O To estimate the mouse population size using the mark and recapture method.arrow_forwardThe island of Guam in the South Pacific had no natural predators until the early 1950s, when the brown tree snake was accidentally introduced by either ships or aircraft shortly after the Second World War. Scientists studying the effects of this invasive species surveyed five different native bird species in an area of northern Guam that the brown snake had recently invaded. The graph shows the population data of the five different native bird species from 1976 to 1998. Which of the following best describes the data and explains the effect of the arrival of the brown tree snake on Guam’s native bird species?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
