Amphibian

humans began migrating from region to region, the spread of a fungus called Chytrid began to take shape. As the fungus spread, the amphibian population began to dwindle. El Valle de Anton is important because it shows how a mass extinction can occur from the spread of a fungus, all because of human travel. It is important to stop the spread of this fungus to keep amphibians away from extinction. 2. A Uniformitarian thinks that a species can perish during a long and slow period of time. Also,…

Pike Fishing Because of their distribution, Northern Pike fishing is a very popular form of fishing throughout not only North America, but most of the Northern Hemisphere. Pike fishing is regarded as a popular form of freshwater sport-fishing or game-fishing Familiar to both freshwater and brackish waters (saltier or more saline than freshwater, but less saline than saltwater) of the Midwestern and Great Lakes areas of the United States as well as parts of Canada and Europe, Northern Pike is…

have to travel greater distances to find suitable conditions, experiencing greater risks of extinction” (Sandom et al 2014). Results have shown that late Quaternary climate change velocity was related with low modern species endemism of mammal’s amphibian and birds signifying that high extinction rates in the past was more prevalent in more climatically unstable regions. In a report done by Stephen Wroe and his team which studied how Climatic changes influenced the extinction of megafauna he…

The country glows and gushes with an abundance of plants, birds, reptilians, fish, amphibians, and even ranks first in the world in the amount of mammal species it has. "It has been calculated that of seven hundred and fifty mammal species living in South America, three hundred and forty are indigenous to Brazil" (Shields 15). Another spot…

excessive growth of plants, especially the Totora (cattail), a reed that grows up to 4 meters high. The Totora, is an invasive species that displaces native flora and occupies large areas of the Everglades that can no longer be populated by fish, amphibians and birds. This situation ends with the base of the food chain and is causing the extinction of hundreds of native species like the alligator, manatee, big mouth bass, blue heron, wild cat, short-tailed hawks, among others. On the other hand,…

Richard Wilbur’s poem “The Death of a Toad” recounts the injury and inevitable death of a garden-dwelling amphibian. The casualty of the piece is fatally mangled, yet manages to find shade as his final resting place. Through the manipulation of structure, as well as the use of both symbolism and emotionally charged diction, Wilbur contends that the peace experienced by the toad in death is preferable to life in the dystopia mankind has created. Wilbur chooses not to employ regulated meter…

American Alligators Scientific Classification Kingdom – Animalia Phylum - Chordata Sub-Phylum – Vertebrata Class – Reptilia Order – Crocodylia Family – Alligatoridae Genus – Alligator Species – A. mississippiensis Scientifically named as A. mississippiensis is at the top of the food chain as no other animal preys upon them except armed humans. They inhabit in fresh water swamps, marshes, river, lakes and canals. Can be found throughout the southeastern United States from the coastal…

In higher vertebrates, such as amphibians and mammals, two blood coagulation pathways exist which both trigger the activation of thrombin through enzymatic cascades: an extrinsic tissue factor pathway, initiated mainly by internal or external trauma, and an intrinsic contact activation pathway, which is employed to repair minor external damage and injures. The binding of tissue factor (TF) to activated factor VII (FVIIa) is essential in the commencement of the coagulation cascade, as it serves…

Alongside many eye-colors, they also have much variety with their pupils. Some frogs have sticky padding on their feet while others have little webbed feet. If not even all frogs have all of the same qualities, how can we tell what species the little amphibian in our garden is? Toads too have numerous shapes, sizes, and textures, but they don’t have too much variety in color and usually end up brown. Toads are usually broader and flatter than frogs. Toads are also quite chubby and have…

The article was about an old reptile named the Dimetrodon. It was based back even 50 million years before the dinosaurs came to be and was the biggest land creature of its time but was only the size of a small crocodile. There is very little that any scientist knows about the Dimetrodon except its size and habitat.Until October 14 when researchers discovered the animals diet. At a pit in Seymour, Texas Paleontologists, Bakker, and Stephen Hobe found the fossils of many Dimetrodons and small…
