In 1956, two Corsican mouflon sheep were introduced to Haute Island, which has an area of 7.00 km^2. In 1957, the pair were able to reproduce for the first time. By 1977, the population had grown to 600 sheep due to abundant food sources and the lack of natural predators in the area. Since then, the Haute Island sheep population has fluctuated between 200 sheep and 600 sheep. In 1990, 250 mouflon sheep were relocated from Haute Island to a neighbouring island with similar terrain, soil, vegetation and weather patterns. The neighbouring island has an area of 10.0 km^2.
1. Compare the density of the Corsican mouflon sheep population on Haute Island in 1977 with the neighboring island in 1990. (three sig digits)
2. Explain how the growth of the Corsican mouflon sheep population on Haute Island caused interspecific competition ?
3. What prevented the Haute Island sheep population from increasing beyond 600 sheep?

Researchers discover two populations of monkey flower (Erythranthe) in Yellowstone National Park. One population is found near geysers and thrives near the hot water. The other population is found in the dry slopes of the mountains nearby. Both populations appear physically similar. Based solely on their observations, the researchers make an initial hypothesis that the two populations of Erythranthe are actually two separate species. This is an example of using the ____ species concept (choose the BEST answer).

A population of lizards in Southern California is orange and is poisonous to birds. In central California, where the two species overlap, a new species of non-poisonous, orange lizards arose. 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. E) Non-poisonous brown lizards are more attractive to mates.arrow_forward
- A small Arctic nesting goose have goslings (baby geese) that exist in two color morphs, grey or yellow. A population of geese included 263 yellow goslings and 413 grey goslings. Assume that grey is dominant and that the population is in HWE. There is no difference between yellow and grey goslings once they have matured. However, yellow goslings are at an increased risk of predation. If 303 grey goslings survive to adulthood, but only 150 yellow ones do, predict the effect of selection on the genotypic frequencies in the next generation. choices: GG = 0.22 Gg = 0.53 gg = 0..251 GG = 0.321 Gg = 0.525 gg = 0.154 GG = 0.175 Gg = 0.632 gg = 0.193 GG = 0.155 Gg = 0.514 gg = 0.331arrow_forwardWhen wolves were returned to Yellowstone National Park in 1995, some of the effects noted were increasing levels of berries available to black bears, stabilization of stream banks, increased nesting habitat for birds, and increasing beaver numbers as a result of rejuvenating aspen trees. These were later determined to be the results of reduced numbers and altered feeding behavior of elk as they were preyed upon by the wolves. Given this information, which of the following best describes wolves in Yellowstone National Park? A. They are a primary consumer B. They are an ecosystem engineer C. They are a foundation species D. They are a keystone species E. They are a flagship speciesarrow_forwardTests on wild cheetahs have shown that there is low genetic diversity among individuals. Wildlife biologists and conservationists are worried about what this means for the survival of this species. Why is low genetic variability a big problem when it comes to a species survival in a changing habitat?arrow_forward
- The Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection.

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. Answerarrow_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_forward
- African elephants are threatened by poachers, who kill the elephants for their tusks. Both male and female elephants can grow tusks. There are some elephants that are tuskless (do not grow tusks). In the elephant population of Gorongosa National Park, the number of female elephants was monitored for many years. The graphs show the total female elephant population and the percent of tuskless females in that population from 1970 to 2015. Which of the following describes the trend in the female elephant population from 1970 to 1995 ? The overall population decreased, and the proportion without tusks increased. Answer A: The overall population decreased, and the proportion without tusks increased. A The overall population decreased, and the proportion without tusks decreased. Answer B: The overall population decreased, and the proportion without tusks decreased. B The overall population increased and then decreased, and the proportion without tusks…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_forwardThe spotting pattern of a guppy is inherited. A spotting pattern that is easy to see in the environment helps a guppy attract a mate. Observe the changes in the image attached below that occurred over 15 generations. The setup happened at 2 aquariums one with fine gravel and no predator present and another with course gravel and no predator present. The guppy populations diverge in their spotting pattern because… A) the guppies that were easily seen successfully found mates and that spotting pattern increased in frequency. B) the guppies that were easily seen were found by predators and that spotting pattern increased in frequency in the following generations. C) the guppies changed their spotting pattern to avoid predators in their environment. D) the guppies changed their spotting pattern to attract mates in their environment.arrow_forward
