In early 1995, grey wolves were reintroduced into Yellowstone NationalPark where they had previously been completely exterminated.Wolves are large social carnivores that hunt in packs and usually feed on elk or sometimes deer. They killmostly young and old animals, a practice that removes those elk least likely to survive harsh winters. Wolvesnormally breed once a year, but when prey is scarce and/or pack sizes are large, many females may not becomefertile. Litter sizes vary from three to six pups, depending on available food. Studies of wolves in the centralCanadian Rockies reveal that unequal numbers of males and females exist and that dominant (alpha) malesmate only with (alpha) females.The reintroduction of grey wolves to Yellowstone has affected the entire Yellowstone Basin Ecosystem.Field biologists report that elk are huddling in large groups for protection and that grizzlies are fightingwolves. Coyotes are about half the size of wolves, and each coyote pack has a smaller territory. They aresometimes killed by wolves when the two species fight over elk carcasses. Wolves disturb coyote den sites andsometimes kill and eat the young. The wolves have killed about 36 coyotes since their introduction. Biologistsmaintain that wolves have returned the ecosystem to a more natural state. The wolf populations have grownfrom the 31 wolves that w ere reintroduced to 53.Wildlife enthusiasts have thronged to Yellowstone to watch wolf packs from roadsides, but the strongdispersal capability of wolves means that wolves and landowners often have encounters outside the park.Ranchers and farmers had resisted the reintro duction of wolves to Yellowstone and had predicted that hundredsof livesto ck would be killed. Wolves that prey on livestock are usually shot.

Upland game hunters in Illinois have been noticing a decrease in therabbit and pheasant populations over the past five years. They havelobbied the Department of Natural Resources and the statelegislature to allow them to shoot red-tailed hawks, one of therabbit’s and pheasant’s main predators. Explain why shooting hawkswill not ultimately solve the problem of a decreased rabbit andpheasant population
The Atlantic cod population is of primary economic importance to fishingcommunities throughout the maritime provinces in Canada. Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.
In 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.…

One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. 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. The carrying capacity of seals would remain the same, but the population of seals would decrease.
Populous nations such as China have instituted strict policies tocurb population growth. In 1979, China implemented a “one-child”policy.Do you think that such strict control methods are appropriatefor population control?
The long-leaf pine forest ecosystem once extended across 95 million acres of the southeastern US. However only 5 million acres now remain causing major declines in the Gopher tortoise population. Given this, what is expected to happen to overall diversity of species that depend on Gopher Tortoise burrows?a. increaseb. decreasec. stay the same
In a population of sociable weavers (small birds that live in the African savanna), body weight was recorded for 977 birds and graphed. (n) Identify and describe the type of selection that is occurring in the population of sociable weavers. (o) A group of fire ants from North America were accidently brought to African savanna by an American tourist in their luggage. The fire ants bite and cause harm to all organisms and their food supply in the savanna. Explain how the fire ants will impact the ecosystem dynamics

* This is a made up animal. Could dispersion be a population characteristic for the following animal. Their specialized energy consumption (diet) needs to undergo multiple energy transfers with considerable energy losses (radiant energy to aquatic animals) to support their species. is a slow-moving carnivore with a duck bill, flippers, a long neck, and a short range of motion. Is slow and awkward, with no fangs, claws, or nails. While this species is a mammal, it also has the ability to lay eggs as a part of its reproductive cycle. However, a female Jacks can only lay one egg every 5 months. Unlike similar freshwater semi-aquatic mammal species, the beaver, the Platyoth, doesn’t build itself a home or nest instead, it roams. At night, the Jack will locate riparian sedges to hide for sleep.
The global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?
