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.

In 1995, a population of 31 gray wolves was introduced into Yellowstone National Park. The population of the gray wolves fluctuated in the 20-year period after introduction. In 2019 an estimated 80-110 wolves are present in the park.
Wolves, elk, and bison are native to Yellowstone, but the wolves disappeared in the 1920s due to excessive hunting. Wolves are primarily carnivores, and elk and bison are primarily herbivores.
A team of scientists monitored the population of wolves in Yellowstone for the first 20 years after their release.

You are part of a group of researchers examining the survivorship and fecundity of Bengal Tigers (Panthera tigris tigris) in the Kalakkad Mundanthurai Tiger Reserve in the South Indian state of Tamil Nadu. Parts of the reserve are well-protected from poaching, and other parts are largely unprotected. 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. Also, note that Sx is listed here -- this is related to, but is NOT the same as lx… To calculate r, use the formula r = ln(Ro)/T.

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_forwardYou are watching a documentary on television about grizzly bears in North America.

She says that grizzly bear populations are rising for the first time in several decades even though deforestation is still a growing problem in North America. Which of the following could be a possible factor for the increase in the grizzly population?

- In this task, you will assume the role of a wildlife biologist that must decide if reintroduction of cougars into the Eastern US is a feasible mitigation strategy for addressing white-tailed deer overpopulation. 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_forwardTigers are solitary animals that require vast amounts of forest landscape as their territory to roam. In order to protect one tiger, we must conserve around 25,000 acres of forest. With poaching and deforestation threatening their survival, what are possible solutions to bring tiger populations back from the brink of extinction?arrow_forwardWolves recolonized a large area around Grand Teton National Park (GTNP) in the late 1990’s. Wolf biologists started estimating the number of wolves in 2000 at 21 wolves in GTNP population. In 2010 they repeated their population surveys and counted 105 animals.The population growth rate of wolves is 8 per year.State biologists want to know how long it will take for this population to reach 175 wolves so they can delist them in this region of Wyoming. How long will it take for the population to reach this threshold, assuming growth stays the same?arrow_forward
- Pronghorns look very similar to antelopes and are considered the fastest mammal in North America. They can be found in the Southeastern parts of Alberta. In the 1800s, it is thought that the population of pronghorns reach 35 million in the Prairies. By 1924, only 20,000 pronghorns could be found in Alberta. In 1996, only 9,600 remained. What is the per capita growth rate of pronghorns in Alberta between 1924 and 1996? Express your answer as a value between 0 and 1 rounded to two decimal places. If the population is decreasing indicate this with a negative sign. Answerarrow_forwardEastern loggerhead shrike is a critically endangered species of bird in Canada. Its population has been declining since the 1960s, and it has been speculated that habitat loss, pesticide usage combined, and climate change have affected the shrike population size. In 2004, there were approximately 70 loggerhead shrikes breeding in Canada. Over the next five years, 111 new shrikes were born, 57 died, and 15 left the area. Calculate the change in the population of eastern loggerhead shrike between 2004 and 2009. Express your answer rounded to the nearest whole number.

Which of the following statements best explains the existence of non-poisonous orange lizards? A) Non-poisonous brown lizards changed color once they noticed birds did not eat orange lizards. B) Non-poisonous orange lizards have a selective advantage since birds avoid orange lizards. C) Non-poisonous lizards turn orange by eating orange flowers and then pass the trait on D) Non-poisonous orange lizards have a selective disadvantage since they cannot blend in.
