Threatened species

Endangered species are organisms that have such a reduced population that they are threatened with extinction. There are thousands of different species that are included in this list. Millions of years before humans existed, causes of extinction of living things were mostly linked to geological and climate effects (environmental change). Even though, environmental change is still the primary root for the extinction of organisms, but now the process of extinction is accelerated by human…

The Endangered Species Act, like many of the conservation acts, was put in place because people noticed something needed to be done. Although this act is very complex and can be confusing, it has been successful. Nonetheless, since many species are still listed or waiting to be assessed people criticize the act’s effectiveness. In 1966, congress passed the Endangered Species Preservation Act. This listed native animals as endangered and gave limited protection. The act was amended in 1969 to…

Biodiversity and ecosystems work hand in hand with one another. Without one, it is unlikely to have a thriving version of the other. Biodiversity is defined as the variety of species that are found in a natural state. Many consider this to be talking about species of animals, however, this includes ecosystems and genetic diversity. Chapter six tells how biodiversity contributes to what we know as biological wealth. This can largely determine how one sees a country’s wealth and economical capital…

a. (EARTH) does have a case to challenge the FWS and NMFS decision not to list the shad. The Endangered Species Act (ESA) was made to stop species that are on the road to extinction, and put them on the path of recovery. The big mouthed shad is one of those species, which relies on Maine rivers for its lifecycle. The FWS and NMFS have completed a status review and have decided, against contrary data, that the fish should not be listed. Much like the spotted owl case (NORTHERN SPOTTED OWL v.…

different species of crocodilians, and produce a series of 10 bullet points below the name, listing interesting and important facts that relate to each of those species. Species 1 - American Alligator, Mississippi Alligator, Pike-headed alligator, "gator" (Alligator mississippiensis) (Britton 2009a) Picture: Figure 1 - Alligator mississippiensis(Hillman 2004) 1. Alligator mississippiensis of the order Crocodylia and the family Alligatoridae. 2. It is classified a “threatened” species on the US…

For instance, the way in which mussels help purify water affects humans and how trees provide oxygen for living species. The variety of life within our planet can be described as biodiversity. Biodiversity can be described as an umbrella term that elucidates the variety and variability of nature. It encompasses three basic levels of organisation in living systems: the genetic, species, and ecosystem levels (Admin). However, within this paper, biodiversity will be explained on a much smaller…

For example, if one little species that had no purpose on earth were to be endangered, they would find a way to solve and save the species from extinction. Carpenter explains that humans attempt of trying to conserve wildlife has expanded into more of a world wide type of problem. Some of the Fresh water has also been tampered by humans. The author claims that chemicals in freshwater can lead to toxicity, odor, deoxygenation, and the elimination of many species of fish. In the article,…

Australian native species are currently threatening the Australian ecosystem’s ecological balance. A major contributor to these pressures is the introduction of mesopredators such as foxes and feral cats. These species have been able to strive in the Victorian region as Australia’s native apex predators such as the dingo, have been removed or culled from the area (Milman, 2015). Therefore, with no threat of predation, no fatal disease threats and an extreme reproductive rate, these species have…

Endangered Species Imagine the world where species are dying because they couldn’t find food because there food is extinct. The world would turn into chaos just because of one species. So if the government could save that one endangered species then we could stop the world from going into chaos. Endangered species have a huge impact on the world and if they go extinct it can mess up everything. “Endangered species does not just refer to wildlife but rather any living organism whether in the air…

Biodiversity is subjected to numerous forces that threaten the loss of species and the depaupering of natural resources (Brand et al., 2008). Biodiversity loss drivers (mechanisms that influence the extinction of a species) are generally encompassed in (but are not limited to): environmental stress, large environmental disturbances, extreme environmental conditions, severe limitation of resources, the introduction of non-native species, or geographic isolation (Slingenberg et al., 2009). The…
