Imagine that you are a scientist studying species interactions in Kruger National Park, South Africa. Today, you are observing a pride of lions in the southeast quadrant of the park. Two lionesses brought down a large adult wildebeest. The adult females fed for approximately 20 minutes. Their cubs appeared interested in feeding but were largely kept away from the kill by the adult lions. A clan of hyenas drove the lions from the carcasses and fed for approximately 30 minutes. Two male lions drove the hyenas from the carcass, killing a female hyena. The male lions ate most of the kill; vultures fed on remains.1. Species Interactions• Describe the form of species interaction that was observed between members of lion pride and between lions and hyenas.• Explain how this type of interaction may affect the population densities of the two species.

The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d.

- Mongooses 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_forwardOn the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. If one builds a canal linking a predator-rich pond to a predator-poor pond, then what type(s) of selection should subsequently be most expected among the mosquitofish in the original predator-rich pond, and what type(s) should be most expected among the mosquitofish in the formerly predator-poor pond? stabilizing selection; directional selection stabilizing selection; stabilizing selection less-intense directional selection; more-intense directional selection less-intense disruptive selection; more-intense…arrow_forwardThe brown tree snake is native in areas such as Australia and eastern Indonesia.

- When 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_forwardIn 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…arrow_forwardIn 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals.
