Nutria Rats

First, rat infestations are large numbers of rats entering an area and causing chaos among the population. The quote in article 1 “The increase in late-season grass and seed was a major factor in greater native

The article “Nutria, Eating Louisiana’s Coast” goes into great detail about nutria rats and their effects on the Louisiana area. It also presents the reader with facts that prove what the author is explaining.

I researched the Everglades in Florida. There have been many negative changes in this habitat both from humans and other species. The region’s water resources are being depleted by invasions of exotic plants such as the Australian Melaluca. The Australian Melaluca also affected the native species of which the rest of the ecosystem depends. Another effect on the water is the runoff from agricultural operations, which gets into the water and pollutes it. Development pressures from agriculture, industry, and urban areas have destroyed more than half of the original Everglades

The salt marsh harvest mouse is listed as an endangered species in 1970s. Its phylogeny is of the Kingdom Animalia, the Phylum Chordata, the Class Mammalia, the Order Rodentia, the Family Cricetidae, the Genus Reithrodontomys, and the Species raviventris. The closest living relative of the salt marsh harvest mouse, according to genetic mapping, is the plains harvest mouse, R. montanus, a western interior species that are found in Mexico and central US.

What is it like to be a barn rat? A barn rat is probably a term that you have never

The nutria, also known as the river rat or the coypu, is an invasive specie because it can destroy the land. Nutria are rodents similar to the capybara because of its body shape and brown fur. It is also similar to beavers

First, this mainly due to the fact that O’ahu tree snails have unique colorful shells, and as a result, many people are removing these snails and using them for scientific studies or cases (Kay and Hadfield, 1972). In other words, the snails are being taken away from their natural habitat and kept in laboratories for scientific studies. However, most humans are not aware that they are disturbing their environment and having a negative impact on the overall population of Achatinella mustelina. Moreover, many shell collectors and nature enthusiast in the late 1800s and early 1900s collected these Achatinella mustelina because of their colorful, flamboyant and patterned shells which in return negatively impacted the number of these specimen (Hadfield 1986, Hadfield et al. 1993). For this, shell collectors and nature fanatics have to be aware and appreciative of the impact and effect that wildlife animals have on the environment as well as the ecosystem as a whole. In other words, when human forces disturb a species habitat or environment, they are negatively impacting the ecosystem thus increasing the extinction rate of endangered

In the article about the rats it talked about how construction and the mild winter caused reasons for the rat surge. I would expand on this section of the article and go into more detail as to why. Also, I would get in contact with a construction worker who has experienced rats and their views.

Firstly, the author states that pollution sources such as oil rigs near Alaskan beaches is killing the sea otters. Also, a research held on water samples in the area showed that it contains high levels of chemicals that may indirectly kill the otters. This view is objected by the lecturer. He proposes that Orcas use the animals as source of food, that is why there are no signs of dead otters on shores of Alaska, which would however be

Second, the reading states that park wildlife was affected as well. In contrast, the professor in the lecture averts that the small plants that grow create ideal

8) Increased quality of salt marsh vegetation may improve habitat value for the salt marsh shrew.

The Eastern Gray Squirrel or Sciurus carolinensis is an invasive species for the Western United States. Native of Eastern North America, it was brought to the west through people releasing them in a variety of places such as parks (Hoefler 1990). Even though it was brought away from it’s natural

Nutria are large semiaquatic rodents that appear to look like beavers with long, thin tails, however they are considered to be an invasive species. They survive in swamplands and typically other wetlands surrounding Louisiana. These organisms have created a problem to the Louisiana environment by creating openings in the marsh vegetation that sustains the Louisiana coastline and by weakening flood control levees that protect low-lying areas. Nutria are also known for their high procreative rates. Because of this, maintaining a well balance between the factors of supply and demand are difficult. Preventive measures and other available techniques have been presented in order to alleviate ongoing damage and to reduce the levels of damage already

When walking through local woods or the parks in the area you would be hard pressed to avoid seeing what most consider to be a pest or nuisance that is very common to many regions of the United States. The eastern gray squirrel is an arboreal animal that has been native to this country for a long time and serves as a useful part of the ecosystem. This creature has an interesting background and a comparatively short lifespan. It is comprised of several major organs just like humans especially it’s digestive system. The gray squirrel is a mammal that is been on this planet for millions of years and may have even walked the earth with dinosaurs. The common squirrel is not the nuisance many think it to be but instead is essential to the ecosystem east of the Mississippi river.

In this investigation of the ecological niche of the woodlouse, I chose to experiment the amount of soil moisture that the slaters tend to prefer. I chose this aspect, as moisture is a vital part in the survival of this small creature.
