Research Paper On Bald Eagles

326 Words2 Pages

Bald eagles are found in many environments in the United States. Those environments include deserts, mountains, freshwater, and marine areas. Bald eagles are known to build very large nests in treetops and always near water. The main source of food for bald eagles is fish, but they will sometimes eat other small animals.

In the 1900s the Environmental Protection Agency listed the bald eagle as an endangered species. During those years, DDT usage was widespread, and it is believed that its use was responsible for the decline in the number of eagles. DDT is a chemical that was used to control mosquitoes, and it caused a thinning of the eagle egg shells.

The population of breeding pairs of bald eagles has changed in several states over a 12-year period as is shown in the table below.

In the dirt habitat, the population of fork and knifes began to decrease while the population of spoons began to increase. For instance, in generation 2, forks accounted for 33% of the population, knives had become extinct and spoons accounted for 67% of the population. Additionally in generation 3, the total population was made up of spoons, both knives and forks had become extinct (Table 1A). As for predators in the dirt habitat, the population of pinto bean decreased during the second generation, while the populations of black beans, green beans and white beans slightly increased.

Research Paper On Prairie Dogs

112 Words | 1 Pages

Black tailed prairie dogs are burrowing rodents that live in large colonies in the grasslands of central and western North America. They emerge from their burrows in daylight to forage and feed on roots, grasses, and seeds. Their head and body are 12-15 inches tall, and their tail is 3-4 inches tall. Prairie dogs are considered a keystone species because their colonies create islands of habitats that benefit approximately 150 other species. They are a food source for coyotes, black footed-ferrets, eagles, and badgers.

Exterminate Gray Wolves

Not long ago about, 250,000-500,00 Gray Wolves (Canis Lupus) roamed North America. In the 1930’s people decided to try to exterminate them. Once they were endangered, people realized what an impact Gray Wolves have on the environment, as well as the effects they have on other animals. Gray Wolves range in color from grizzled gray or black to all-white. Gray Wolves eat ungulates, or large hoofed mammals, like elk, deer, moose and caribou, as well as beaver, rabbits and other small prey.

Sage Grouse Research Paper

I believe that the greater Sage Grouse should have been listed as endangered because our economy shouldn’t be heavily as affected by a specific species. It should not come to a point in society where there needs to be a decision made to prioritize either the ecosystem or the economy. The general issue is economic independence for an area, such as the West. Our economy relies on these natural resources for distribution purposes. Therefore both the economy and the ecosystem need to be thriving well still conserving.

Malleefowl Taxonomy

An examination of Malleefowl population dynamics is required for recovery actions to be efficient. Actions: Conduct PVA to derive a quantitative comprehension of Malleefowl population viability. The PVA can determine the management scenarios that would promote the long-term persistence of Malleefowl populations under varying stochastic events such as fox predation (Bode and Brennan 2011). Bode and Brennan (2011) using a PVA (stochastic age-structured) model noted that a remote population of 32 breeding birds may become extinct in a 20-year period, but introducing captive-reared juveniles have shown to reduce their decline (Figure 3).

Wild Animal Proposal

WILD DOG REINTRODUCTION FEASIBILTIY STUDY PROJECT PROPOSAL Introduction Human-mediated translocations of living organisms have become a common tool in shifting the range of a species (Seddon, Soorae and Launay 2005). The development of capture and transport techniques have facilitated these translocations of animal species across landscapes within and outside of perceived natural distribution ranges (Schemnitz 1996). These translocations have occurred for various reasons, namely; the use biological control agents (Hoffmann and Moran 1998), aesthetical (Griffith, et al. 1989) and more recently the wildlife trade and ranching industries, which have deliberately moved species into areas outside of their natural distribution ranges to generate
