Chapter 31.5, Problem 1TC
Summary Introduction
To describe: The events that happened to the population of coyotes and white-tailed deer between 1700 and now in terms of their range and abundance.
Introduction: Before 1700, wolves roamed over almost all-over North America, coyotes were found mostly in the west of the Mississippi, and white-tailed deer lived throughout the eastern United States, and here most of the land was covered with coniferous or deciduous forests. Wolves reduce the coyote and white-tailed deer population by chasing and hunting them.

Imagine three islands, each with a population of frogs. There are approximately 1,100 frogs on Island 1, 400 on Island 2, and 400 on Island 3. Researchers estimate that these populations have been separated for 800 years. Individuals in these populations show variation in markings on their body by shape and color. Frogs on Islands 1 and 2 have circle markings that are either red, blue, or purple. All frogs on Island 3 have yellow triangle markings.
The islands recently became a tourist destination, with new passenger boats connecting Island 1 and Island 2, and Island 1 and Island 3 (there is no boat that goes between Island 2 and Island 3).
Would a biologist agree or disagree with the following statements?
part 1:
It is possible that yellow or triangle markings exists on Island 1 at some point in the past.
Question options:
Agree
Disagree
part 2:
Genetic drift is not occurring on Island 1.

- 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_forwardWhy are population sizes not constant in biology?arrow_forwardIs there evidence that random genetic drift in the inbred Swedish population had led to a decline in mean fitness that was sufficient to cause the extinction of the population?

- The northern hairy-nosed wombat has experienced historical population declines, though population have stabilized recently due to conservation efforts. While studying them researchers noticed the following fluctuations in (effective) population size: Year 1: 100 individuals Year 2: 90 individuals Year 3: 50 individuals Year 4: 75 individuals Year 5: 90 individuals Year 6: 95 individuals A. Given this information what is the long-term effective population size of this particular population over the six years? B. Assume that at the start of the study the researchers determined heterozygosity for this population to be 0.63 at microsatellite loci. What would you expect the heterozygosity to be at the end of the six years?

- New Zealand snapper populations were found to be under the influence of genetic drift, suggesting overfishing was still an issue for them, despite the New Zealand fisheries estimating their total population size to be over 3 million. Which of the following is the best explanation for this observation? A) Pelagic fish, like the New Zealand snapper, often only have a few reproductive individuals, therefore their effective population size is actually much smaller than the total population size. B) Pelagic fish, like the New Zealand snapper, often have an equal sex ratio which affects the number of breeding individuals. C) Pelagic fish, like the New Zealand snapper, often have disassortative mating which affects the number of breeding individuals.

Over a period of several years, you’ve gathered demographic data (summarized below) on tigers in both poached and unpoached locations; assume that mx numbers represent female offspring born per female. Note that your demographic data begins at age 1, and does not include survivorship of cubs from birth to age 1.

Based on several samples, he finds an average of 9 prairie dogs living in an area of 7.0 m2.If he knows that his field is 4,000 m2, what is the approximate size of the prairie dog population?
