Amphibian

marshes, beaver’s ponds, salt marshes, mudflats, harbors, and human-created canals and ditches. To feed, they have to be near wooded wetlands near shallow bodies for feeding. These waters should be abundant in small fishes, crustaceans, reptiles, amphibians and a whole abundance of different species. They will roost close or on the ground and perch on stumps, trees, or submerged debris. Green herons typically nest near water on hammock in a marsh or in a tree, but nest in trees or shrubs away…

Examples of amphibians during the said period are the Temnospondyls and Nectrideans. In terms of the reptiles, the herbivores dominated. Among them were the pareiasaurs, which had a thick armored skin on the dorsal side, pelycosaurs, which was distinct for its large spines…

Endocrine disruptors is the given name for a group of chemicals that, at certain doses, can interfere with the hormone system within mammals as well as fish and amphibians. They can be naturally occurring chemicals e.g. Arsenic, or manmade chemicals e.g. hormonally active substances excreted by humans using certain pharmaceutical products, as well as a number of chemicals derived from everyday cosmetics, plastics and personal care products. These disruptors can lead to a variety of debilating…

occurred. The fossils records have few of the transitional form that shows the missing link between two species due to the nature of terrestrial environment. The example of this was the discovery of Tiktaalik which is the missing link between fish and amphibian. In his Your Inner Fish book, Neil Shubin wrote that when he brought the fossil of Tiktaalik to his son’s preschool class, and asked the children what the creature was. He got some five years old children arguing, “No, no, it isn’t a…

They decrease biodiversity and pollute water resources. Roundup herbicide has been shown to cause birth defects in amphibians, embryonic deaths, and organ damage in animals, even at very low quantities. GMOs negatively affect the environment. The toxicity is a huge issue surrounding chemical pesticides and herbicides, used with GMOs. GMOs may be toxic to organisms such…

The river otter is part of the family Mustelidae, which is the weasel family. They have an elongated body that is widest at the hips with short and stocky legs. Another characteristic of this family is having a muscular neck that is in thickness equal to or greater than that of its head. River otters have a tail that is approximately one-third of their total body length with the end being tapered. They have a small flat head that with small anterior eyes, broad muzzle, long thick whiskers,…

improve their bodies’ structures to adapt the change in their habitat. For this effect, cold-blooded animals are specific examples; according to the article “Amphibians Don’t Cozy Up to Warmer Climes,” based on the information of researchers at Stony Brook University, warmer environment shortens cold-blooded animals’ duration such as fishes, amphibians, crustaceans, and lizards because the constructions of their bodies are more appropriate for the cold environment (Leonard, page2). While global…

49% or half are endemic, 157 are threatened, 128 are threatened endemic. In floral diversity or in plants, between 10,000 and 14,000 species of vascular and non-vascular plants, which half of it is endemic in the country. In amphibians or animals, the estimated total of amphibians is 359 species (101 species) and reptiles (258 species) are known in the…

Lithobates Sphenocephalus, commonly known as Southern Leopard Frog are a part of the Anura order of amphibians meaning “without tail,” and in the Ranidae family, also considered to be “true frogs” which are the most widely distributed family occurring on all continents with the exception of Antartica. The average size of Southern Leopard frogs is about 2-3 ½ inches. The Southern Leopard frog is native to the United States in the eastern region, and contains two subspecies currently: R. s.…

INTRODUCTION National parks have been created all around America. One of the parks in northern California is Lassen Volcanic National Park. Lassen Volcanic has volcanoes, steaming fumaroles, and hydrothermal vents. It is well known for the Lassen Peak eruption of 1915.This essay will talk about History, Climate, Geology, Location, and Miscellaneous. HISTORY Lassen Volcanic was founded in 1915. The last Lassen eruption was in 1915 and from 1916 to 1921 only ash and steam came out of the…
