The Case of the Ivory-Billed Woodpecker: Brad and Mary discuss the discovery of the Ivory-billed Woodpecker. Brad says his team and himself have found proof that the bird is in fact still alive. Mary does not believe that Brad should risk publishing the discovery to the world without great evidence. Including a list of Brad’s arguments and Mary’s responses: “A video clip clearly showing a quite large bird that has the distinctive white wing patterns of the Ivory-billed Woodpecker” - “How can you be sure it’s an Ivory-bill, why not a Pileated woodpecker? They have big white patches on the underside of their wings.” “We have 17,000 hours of sound that include kent calls” - “Your sound may sound just like an ivory-billed Woodpecker, but guess …show more content…

The areas where there is a balance in climate and a good food supply would be the control group. Making the control group a steady area will ensure that the effects are due to the coyote treatment rather than natural complications. The population of the mesopredators would be monitored. Part I (b): Part II: If the coyotes were to be removed, I predict that the mesopredator species will increase in population. Also, the animals may become more dominant because there is no longer a natural predator to fear. Part III: Question) The mesopredator population increased dramatically after the coyotes were taken out of the area. Prediction) The rodent population may have decreased more over time after the treatment because the larger mesopredator animals would need a food source and rodents are at bottom of the food web. Part IV: Question) The primary factor controlling rodent population growth may be the fact that there is longer a large number of predators for them

Last year 110 wolves in 19 packs are back in the wild. On January 16, 2015 the Service published two final rules in the Federal Register: Endangered Status for the Mexican Wolf and Regulations for the Nonessential Experimental Population of the Mexican Wolf. Today, the Mexican wolf has been reintroduced to the Apache National Forest in southeastern Arizona, and may move into the adjacent Gila National Forest in western New Mexico as the population expands. Recently, Mexican wolves have also begun to be reintroduced in

Wolves can control the population of moose by killing the weak moose, making the pack stronger. This promotes a stronger pack and allows wildlife to access the vegetation they need. Without the wolves, the moose would just overgraze. The moose overgrazing leave no food for any other species, which then leads to dirty

The article provides some theories for that the settlements of Chaco Canyon in New Mexico in The American Southwest. However, the professor explains that this evidences aren 't valid and refutes each of the author 's theories. first, the reading passage claims that Chaco structure has been used for residential applications for hundreds of people. The professor refutes this point by saying that this structure may look like an apartment from outside but there is no evidence that proves that this building was used for living. She states that if a lot of people have inhabited in this structure there should be plenty of fireplaces for families to do daily works like cooking.

A remote island that has remained uninfluenced by humans is now on the verge of losing its wolf population due to genetic deformities. The island is called Isle Royale and its once abundant wolf inhabitants have now dwindled to three remaining wolves. This leaves many scientists and researchers with the question of what actions to take in order to save the wolves from extinction. After researching and gathering information, it is clear that the best way to save these wolves is for humans to immediately introduce more wolves to the island in order for the island to flourish, genetic variation to expand, and the number of wolf offspring to rise.

Although it might be true that the sightings of deers by the local hunters have reduced, there might be variety of reasons for the same. The deers might have found a new refuge or might have become increasingly vary of the hunters themselves. Using the empirical evidence from the hunters to imply that the deer population has definitely declined would be incorrect. The argument would have been more convincing if the

How do hunters help the population? Several natural predators of white-tailed deer occur. Wolves, cougars, American alligators, jaguars, and humans are the most effective natural predators of white-tailed deer. These predators frequently pick out easily caught young or infirm deer, but can and do take healthy adults of any size. Bobcats, Canada lynx, bears, wolverines, and packs of coyotes usually prey mainly on fawns.

Conferring the results, we can deduce through correlative analysis that as the total harvest drops, the number of deer increases by a slightly significant variable. This means that deer harvest, is inversely proportional to deer density. The disadvantages of having too much deer in the population should be noted. They lead to lack of food which is a typical cause-and-effect relationship. Deer, being herbivores, feeds on plants directly to obtain food.

Leading them to become overpopulated and the forest to not be vegetated much at all. After the wolves were brought back into the park,they first lessened the deer population which led them to staying away from the valleys which made the trees grow and birds to make homes there. Then, beavers moved into the rivers and valleys,making homes and niches for other species. Wolves would also kill coyotes that made the rodent population rise as well,along with an array of other species. Without the wolves yellowstone park would have remained

Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,

Greenberg explained in the question period how he had always been drawn to birding, and his thoughts on the de-extinction progress and the viability that might be possible for the passenger penguin. He felt that some would find it inspiring or fearful. I agree that de-extinction could help open portals of learning for species that were never studied in life. At the same time, I found it surprising that it could be possible for the passenger pigeon, were that to happen, could be the only species to go extinct twice. Greenberg’s film demonstrated how even an extinct bird can hold many lessons for how one thinks about

The recovery plan for the black-footed ferret (Mustela nigripes) is a collaborative effort between the U.S. Fish and Wildlife Service (USFWS) and the National Black-footed Ferret Conservation Center Office (USFWS, 2013). The species was first listed as endangered in 1967 and “grandfathered” into the Endangered Species Act in 1973 (USFWS, 2013). The black-footed ferrets populations declined because of the close association the ferrets have with the black-tailed prairie dog (C. ludovicianus), Gunnison’s prairie dog (C. gunnisoni), and white-tailed prairie dog (C. leucurus) (USFWS, 2013). The ferret relies on the prairie dogs for food and utilizes the prairie dog’s burrows for shelter. The destruction of habitats through the conversion of prairie land to cropland along with the poisoning of prairie dogs as pests, sylvatic plague and other diseases led to the prairie dog population decline (USFWS, 2013).

Introduction Understanding the natural history of declining species is imperative to find vulnerable life history stages and behavioral specificities that can prevent the slippery slope which leads to a threatened and endangered status. Species specific behavior is often overlooked, but has been a major cause leading to the extinction of species across taxa (Reed 1999). Incorporating behavior specifics into management plans and population models is imperative to species success. Important breeding behavior involved in critical life history stages can influence population dynamics (Reed 1999). Few studies encompass breeding behavior because off the required investment in funding and resources.
