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…
Species that are more vulnerable to certain risk factors are more likely than others to become extinct. For example, species with a unique lineage, such as the giant panda, are likely to be at severe risk of extinction.a. Should our limited resources for species protection be focused on species that are at the highest risk of extinction?b. Do you support the idea that high-risk species may be less successful products of evolution and should not receive extraordinary protection?
We (humans) do not have any ethical burden to worry about other species because extinction is a natural process.

- EVOLUTION LINK Biologists have wondered how introduced species that would probably have limited genetic variation (due to the founder effect) survive and adapt so successfully that they become invasive. Part of the answer may be that invasive species are the result of multiple introductions instead of a single one. Explain how multiple introductions from a species native area to an introduced area could increase that species invasion success.arrow_forwardSome scientists believe we are in the midst of a new phase of mass extinction, influenced by human behavior, threatening the earth’s biological diversity and contributing to widespread ecological crises. How can the study of non-human species help shape human responses to these potential threats?arrow_forwardThe number of extinctions of birds and mammals has gone up as human populations have increased. True or False ?arrow_forward
- Some people declare that we shouldn’t worry about endangered species because extinction has always occurred. How would you respond to this view?arrow_forwardAn extinction vortex describes a) changes in a population’s gene pool that lead to a loss in fitness across time. b) a species ability to adapt to changes in their environment. c) the continuous series of extinctions caused by competition between species. d) a population that has a reduction in fitness because it cannot escape a Hardy-Weinberg Equilibrium.arrow_forwardBecause new species will eventually evolve to replace those that humans are driving to extinction, why is declining biological diversity such a threat?arrow_forward
- Why might the increasing human population result inan increase in the extinction rate of other species?arrow_forwardApproximately 14,000 years ago, the climate in North America began to warm rapidly. At the same time, human hunters migrated to the continent. Which of these most likely resulted from a combination of these two factors? an increase in the rate of large mammal extinctions a reduction in the rate of species change an increase in the amount of interspecies cooperation a reduction in the total number of small parasitic insectsarrow_forwardYou are part of a restoration ecology program that is attempting to reintroduce an endangeredbird to a new habitat in Michigan, where they have been locally extinct for decades. The species went through an extreme bottleneck after they were almost wiped-out due to insecticide use in the 1960s. Maintaining what limited genetic diversity remains is an important priority, especially because disease spread from other bird speciesrepresents a major threat to the struggling populations of these birds. Captive-bred warblersdestined for this site have been genotyped at a neutral marker locus “D” with two alleles, D95and D135. The genotype counts in the captive animals are as follows:D135/D135 = 12, D135/D95 = 20, and D95/D95 = 48 2a. If all the species are used to start the new population, what is the probability that thepopulation eventually becomes fixed for allele D95 through drift?2b. Let’s assume the population stays the same size (as the number of introduced individuals) inthe new…arrow_forward
- How do you think your daily habits might contribute directly or indirectly to the extinction of some bird species? What are three things that you think should be done to reduce the rate of extinction of bird species?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_forwardOne 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_forward
