Textbook Question
Chapter 36, Problem 13TYK
The mountain gorilla, spotted owl, giant panda, snow leopard, and grizzly bear are all endangered by human encroachment on their environments. Another thing these animals have in common is their K-selected life history traits. Why might they be more easily endangered than animals with r-selected life history traits? What general type of survivorship curve would you expect these species to exhibit? Explain your answer.

Very few species on Earth are completely r-selected or K-selected. Many species in their natural habitats demonstrate a life strategy that ranges along a continuum between r- and K-selected strategies. Use this information to answer the 3 sub-parts.
a) Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup.Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only 25% of the pups survive past the first year. Sea otter fur was highly sought after between the 18th century and the early 20th century. Through conservation efforts, the number of sea otters increased. The current world population is estimated to be between 1 000 and 2 000 individuals, and they are considered to be endangered. Their main food source is sea urchins, molluscs, and crustaceans. Sea…
Give your response to the following statement: “Eventually, all species become extinct. So it does not reallymatter that the world’s remaining tiger species or atropical forest plant are endangered mostly because ofhuman activities.” Be honest about your reaction, andgive arguments to support your position.
Which of the following best predicts the consequences of introducing brown rats ( invasive species) to an
island where they did not previously exist?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
The rat population size will likely remain small, and as a result the rats will not be able to outcompete
other organisms for resources.
(Choice B)
B
Without its typical food sources, the rat population will not be able to become established, and the
island ecosystem will remain stable.
(Choice C)
The rat population will grow rapidly, disrupting the island's community structure by feeding on native
plants and animals.
(Choice D)
D
Without any natural predators, the rat population will become established and help increase the
species diversity of the island

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_forwardThe type III survivorship curve is found in species in which most individuals die when they are young but a relatively small number of older individuals can live for a long time. Many of these organisms have very long lifespans. This would appear to contradict the evolutionary theory of aging because most individuals die when young but lifespan is long. How can you explain this apparent contradiction. Group of answer choices -older, larger individuals have most of the offspring -all type III organisms have very slow metabolisms -type III organisms are trying to prove evolution wrong -type III organisms die at a constant ratearrow_forward
- For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.arrow_forwardMongooses are not native to Hawaii. They were intentionally introduced on all of the islands in 1883 by sugarcane farmers to control rat populations on sugar plantations. They have since greatly increased their population on some islands, while no populations of mongooses are found on the islands of Lana’i and Kaua’i. Which of the following correctly identifies a challenge mongooses would face if they were introduced onto these two islands? A - There is a lack of rats and other food sources on these islands. B - These two islands have no forest reserves compared to the other islands. C - These islands contain no natural predators for mongooses so they would overpopulate. D - These two islands contain native species of birds and reptiles that would compete with the mongooses.arrow_forwardTwo ecologists walk into a bar. After a few drinks, they begin to argue about which would be at greater risk of extinction: a population of 100 African elephants (Loxodonta africana) or a population of 100 house mice (Mus musculus).

- You are watching a documentary on television about grizzly bears in North America. The narrator is speaking over a clip of two cubs and their mother walking along a riverbank in a heavily wooded forest. 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? Loss of habitat Reduction of resources Increased industrialization Higher birth rate over death ratearrow_forwardCalifornia 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_forwardIn 2011, approximately 23% (1138) of mammal species and 12% (1253) of bird species were globally threatened. These two groups have been thoroughly studied. The case with other groups of organisms is not well known. A large number of the threatened species are concentrated in tropical rain forest habitats, where biodiversity is high.
