Following the reintroduction of wolves to Yellowstone National Park in 1995-97, the regrowth of aspen trees became a worldwide story, highlighting the importance of large predators. The wolves ate elk, which browsed on aspen. When elk numbers fell, aspen stands rebounded and birds and beavers returned. Such ecological effects caused by the addition, or removal, of a top predator are called. Score: 4.2/5 (14 votes) . In 1995, however, wolves were reintroduced to Yellowstone; this gave biologists a unique opportunity to study what happens when a top predator returns to an ecosystem. They were brought in to manage the rising elk population, which had been overgrazing much of the park, but their effect went far beyond that. Defenders of Wildlife and the redoubtable Renée Askins (founder of the Wolf Fund in 1986 for the sole purpose of reintroducing wolves into Yellowstone) were among the many who led the way. Others must now carry on to complete the task of defining a place for wolves on landscapes outside park boundaries and to restore other endangered species. The wolves should be left alone. If the wolves die out, people should monitor the effects that no wolves have on the ecosystem. If this has negative effects, the wolves can be reintroduced. Wolves are not the original predators on Isle Royale. There is a possibility that having no wolves is good for the environment. A sudden decline in wolf populations can trigger an ecological collapse, as it did in Yellowstone National Park in the 1920s. Research has also suggested that the presence of wolves could help.

And while elk are the favorite food of the park's wolves, John Vucetich says "you don't need wolves in the picture at all the explain the population drop.". There's consistent evidence that large predators help keep populations of large herbivores in check, with positive effects on ecosystem health." Densities of large mammalian herbivores were six times greater in areas without wolves, compared to those in which wolves were present, the researchers concluded. They also found that combinations of. Gerald Corsi / Getty Images. Last week, Idaho governor Brad Little signed a bill into law that allows hunters to kill about 90 percent of the state's wolves.

Without wolves taking the weak old and sick animals they take food from stronger and younger animals. Winters are hard and food is scarce. By culling the weak the herd gets stronger. Also there is over feeding on existing resources. Over feeding can deprive a species of their particular main staples and negatively affect the whole herd. One of these major costs of anti-predatory behavior of elk is a compromised diet that results in poor health. Elk must do what is necessary to survive, even when there are negative effects associated with their new behaviors. When an animal feels the cost of anti-predatory behaviors, those costs are called risk-effects. [2] Some risk-effects. effects of individual traits, pack size and composition, and ecological factors influencing female reproductive performance (Stahler 2011, Stahler et al. 2013).

As a top predator, wolves are one of Yellowstone's linchpins, holding together the delicate balance of predator and prey. Their removal in the early 20th century disrupted food webs and set off something called a "trophic cascade," in which the wolves' natural prey (in this case, elk) multiplied, all the while consuming increasing amounts of foliage. The biggest source of deaths is not wolves or any other predators. It is respiratory and digestive problems, disease, weather, and birthing complications. At the end of the book, you quote Doug.
