Summary Introduction
Introduction: Biodiversity (biological diversity) is the difference between the organisms. From the population to the ecosystem, biodiversity takes place in all level of ecological organizations. Biodiversity measures the variation at the species, genetic, and ecosystem level.

- California condors, large, predatory birds that were previously on the edge of extinction, have benefited from a program that raises birds in captivity and then releases them into the wild. The reintroduction program, however, is having variable success.Which of the following would have been a surprise to wildlife biologists who, after successfully breeding and raising condors, were reintroducing the condors to the wild following a precipitous decline in their number in the 1970s? (In 1982 there were only 19 condors in the wild.) Group of answer choices: Reintroduced condors laid the same number of eggs as condor pairs in captivity. Only some of the released condors fed on marine mammals; others fed on carcasses of animals as different as wolves and cows. Twelve of 19 nests had no hatchlings, and nests of the coastal population had shell fragments 34% thinner than those of condor populations more inland. Sea otter and sea lion populations declined in areas where the…arrow_forwardWhich 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.arrow_forwardThe most important reason for declining biological diversity is (a) air pollution (b) introduction of foreign (invasive) species (c) habitat destruction and fragmentation (d) illegal commercial hunting (e) commercial harvestingarrow_forward
- One characteristic that distinguishes a populationin an extinction vortex from most otherpopulations is that(A) it is a rare, top-level predator.(B) its effective population size is lower than itstotal population size.(C) its genetic diversity is very low.(D) it is not well adapted to edge conditions.arrow_forwardA population of 1,492 finches is introduced to a rainforest. Over the next year, the finches show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) a) Yes, this is a suitable habitat. The birth rate is higher than the death rate. b) No, this is not a suitable habitat. The birth rate is much lower than the death rate. c) 589 d) -358 e) 0.155 f) 0.845arrow_forward.

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_forwardConservation hotspots are best described as a. areas with large numbers of endemic species, in many of which species are disappearing rapidly. b. areas where people are particularly active supporters of biological diversity. c. islands that are experiencing high rates of extinction. d. areas where native species are being replaced with introduced species.arrow_forward
