A Review Of A Study On Mesocarnivores

We looked first at the relationship between the wolf population and the moose population. From about 1960 to 1970, the wolf population remained fairly consistent at about 20 to 25 wolves. During this time, the moose population grew steadily from 500 to over 1200. The next 10 years saw a doubling of the wolf population to 50. This same 10 years saw a decrease of the moose population from over 1200 to over 800. Then in 1980 began a two year drastic decline in the moose population, which was brought down to 15. For the rest of the decade, the moose population remained quite low at numbers near 20. During the 1980s, the moose population doubled again from around 800 to

Within the Endangered Species Act, the U.S. Fish and Wildlife Service helps watch over and investigate the health of different species. Then, local and national scientist collects data to determine if a species gets put on the Endangered Species list. The main factor to determine the endangerment of a species is if a large percentage of the species’ habitat has been destroyed. Next, note if the animal’s population has been excessively decreasing, threatened by disease, or any terrorized by any predators. Also, record any man-made

As omnivorous beings, it seems that is both a blessing and a curse to have such a vast amount of meal choices to choose from. In The Omnivore’s Dilemma, Michael Pollan explores the majority of these options and offers a sort of guide on how to make a choice. The UC Berkeley Graduate School journalism professor takes us on an eye-opening ride with this book where we find out horrifying truths on the ingredients of the foods we eat every day and whether our choices benefit our bank accounts more than they do our health and the earth.

The Mexican wolf is the southernmost subspecies of gray wolf in North America, its natural habitat was that of the southwest United States and Mexico, Texas, New Mexico and Arizona as their home range in the US. Mexican wolves typically feed on deer and elk. (Rinkevich, Murphy, & Barrett, 2011). The gray wolves were a menace to rancher’s cattle and farmer’s livestock. Depredation of livestock led ranchers and state governments to declare war on the Mexican gray wolves through public and private bounties. The Mexican gray wolves were successfully removed from the wild. (Foreman, 2004) The Endangered Species Act of 1973 was vital for the protection of the Mexican gray wolf. (Larkin, Noss, & Maehr, 2001) In 1990, the United States Fish & Wildlife Service coordinated and developed a Mexican wolf reintroduction recovery plan to establish a wild population of no less than 100 Mexican Gray wolves in March

Abernathy Field Station has the type of habitat which is suitable to find the American mink (Neovison Vison). To try and assess mink presence in Abernathy Field Station, sardines were used for bait and two infrared cameras were set up. Those two areas by Abe’s Creek were sectioned off because they were the most likely to have a mink living there. The cameras were checked weekly to see if there were mink tracks and scat in the mud. The mink habitat suitability index was used to see if AFS was a place where Minks would live (Loukmas, J. and Halbrook, R. 2001). This model just determines whether a habitat is suitable for a mink to live in. Possible sites were minks might have burrowed were also assessed. The hope was to see how abundant the species are in those areas and if they are not present what might be the reason for

Nature culture dichotomy is a Western world view so it is appropriate to consider using this analytical approach when discussing the issues associated with the re-introduction of the Mexican wolf to other stakeholders because of the areas where they would be re-introduced. The area is important because the people in these areas will have many of the same thoughts on how they view the re-introduction

When you think of a mammal who regularly kills humans, the white-tailed deer does not come to mind. Unfortunately, the white-tailed deer often jumps in front of vehicles, causing more than one million collisions resulting in over two hundred deaths a year. In James Gorman’s article, he persuaded me that by bringing the eastern cougar back to its original home, the number of deaths would significantly reduce. He explains both the benefits and downsides of cougars returning to their natural habitat.

The Allegheny woodrat (Neotoma magister) is a small mammal that is endemic to the United States. They live in the eastern part of the United States in deciduous forests. Their species can be found from the Appalachian Mountains through the interior Highland regions, including western Connecticut to northern Alabama (Castleberry et al 2006). Woodrats are restricted to areas that have rocky structures such as caves, fissures, and boulder piles and live within the spaces between rocks (Castleberry et al. 2006). Rocky habitats are good living spaces for them because the crevices provide protection from predators and also create a den environment for young to develop. Since rocky areas are usually distributed in patches throughout an environment, woodrats are considered to be metapopulations because their populations are separated (Castleberry et al. 2002). Other animals that can be found using the same rocky habitats for denning, roosting, or nesting include the Rafinesque 's big-eared bat (Corynorhinus rafinesquii), Townsend 's big-eared bat (C. townsendii), common raven (Corvus corax), long-tailed weasel (Mustela frenata), eastern small-footed myotis (Myotis leibii), eastern spotted skunk (Spilogale putorius), and American black bear (Ursus americanus) (Castleberry et al. 2006). The different types of species that live in the community creates competition and leaves woodrat populations vulnerable. Competition and predators are examples of factors that

We will attempt to verify that the predator-prey relationship of the Isle Royal of Michigan wolves and moose are also dependent on external factors such as the environment and man. Evidence suggests that this is the case but we intend to reproduce this factor in our model. Cross validation will be used to determine if earlier events can help predict known events that occur decades

The author's foraging meal is his single most perfect meal that is environmentally sound in terms of origin and moral standards. The foraging meal was guided through self-reflection on some key questions, in which needed to be addressed to solve the omnivore's dilemma. The moral and psychological implications of killing, preparing and eating animals, distinguishing between the delicious and deadly in nature, and the modernly American practice of alchemy in our kitchens are all factors to the author's perfect meal.

The history of white-tailed deer in Missouri shows positive and negative influences humans can have on wildlife. During presettlement times, the whitetail was abundant in Missouri, especially in the more fertile and diverse habitats of northern Missouri. The influx of European settlers to Missouri during the last half of the 19th century coincided with a rapid decline in the deer population. Unrestricted market hunting and habitat destruction, such as cutting, burning, farming and grazing forest lands, contributed most to this decline.

This article describes the black-tailed prairie dogs (Cynomys Ludovocianus) and their coteries. Coteries are polygynous social groups that black-tailed prairie dogs live in (Hoogland 1983). In these groups, the one adult male reproduces with genetically similar females. The main purpose of this article is for the author (John L. Hoogland) to communicate and defend his earlier work on prairie dogs. These prairie dogs exist where some females and pups, within the coteries, do not breed (Hoogland 1983). Moreover, black-tailed prairie dogs behave parentally towards non-offspring (Hoogland 1983). In addition, Hoogland classifies black-tailed prairie dogs as cooperative breeders; however, they do not help breeders to the same degree as cooperative breeding birds (Hoogland 1983).

A total of 12 brown capuchins (Cebus paella) will participate in the study. Those subjects will be adolescent females between 4 and 6 years of age. All subjects will be born in captivity in the laboratory, and will have minimal contact with humans. To specify, they will be housed in semi-natural indoor and outdoor areas with constant temperature and humanity, regular feeding schedules, enrichment, and water ad libitum. They will neither be food nor water deprived during testing or at any other time. During the testing phase, six subjects will be actors that pair with an unknown partner of brown capuchin (Cebus paella) from another social group. Partners will be matched as closely as possible on the basis of sex and age.

The overall purpose of the assignment was to observe the various behavioral patterns of the flamingos. The observations included squawking, grooming, head dip, wing flap, and head rub. The study took place in the early afternoon at Zoo Miami, and we observed the Flamingos in their exhibit for approximately fifteen minutes. Data sequences were collected for each of the behaviors listed above and were documented in our notebooks. The data was further analyzed in class.
