Rare species

their lives in extensive burrow systems (Nowak, 1991; O¨ zkurt et al., 2005) and are obligate hibernators during seasons with low ambient temperatures and poor foraging conditions (Armitage 1981). The genus Spermophilus of ground squirrel with 41 species (Helgen et al, 2009) is Holarctic in distribution, occurring throughout temperate and arctic Eurasia from Austria to eastern Siberia, China and Mongolia and ranging across western North…

Chordata Class: Mammalia Order: Carnivora Family: Ursidae Genus and species: Ailuropoda melanoleuca Introduction The Giant Panda is classified as ‘Endangered’ on the IUCN Red List of Threatened Species. Formerly widespread across southern and eastern China, Giant Pandas are now restricted to six mountain ranges at the western edge of their former range. Habitat restriction and degradation represents the greatest threat to this species. Its range contracted as forests were cleared for…

They hunt each other for food. Also, poachers become a problem for animals because of their absence in population poachers will kill and sell them since they are becoming a rare species. Although hunting other animals has become a part of their routine, zoos will provide food for the animals, and they don’t allow poachers to kill any animals in or around the property. Zoos will release these animals once they get to a reasonable…

further our species medical technology. By researching this topic, we’ve stumbled on a creation called “chimeras” which are animals that carry human DNA, resulting in the growth of usable human organs. The article, “The Mammoth Cometh,” by Nathaniel Rich, discusses the use of these chimeric experiments to bring extinct animals back from the…

In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul. If we discuss animal further, we can divide animal into rational animal, which is human, and non-rational animal. The essential feature of “being an animal” is perception. From the Aristotle Introductory Reading: “413b2: What makes something an animal is primarily perception.” Perception is…

planet and that it is the reason why Earth is not going to be able to sustain us for much longer. Many people believe, however, that the population of the human race isn’t the reason for Earth’s decline in resources. It is, in fact, us. We, as a species, are solely responsible for Earth’s sudden decline in sustainability. It is not how many of us there are, it is how we live and how we produce, consume and waste our many resources. One of the biggest issues in todays world has a lot to do with…

Paramecia, unicellular cilliated protozoa, usually are ovoid and elongated. They widespread in brackish environments and freshwater. Length of the species are various ranging from 50 micrometers to 330 micrometers. They feed on yeasts, algae, and small protozoa which are captured by them through phagocytosis, devouring a particle by “wrapping pseudopodia around it and packaging it within a food vacuole” (Campbell and Reece 2011). They also serve as the models for the study of basic biological…

In 1859 Charles Darwin published his book “The Origin of Species”. This book explained his theories of how animals and humans were formed. The beginning of the earth has been a mystery frustrating the minds of scientist for many years. Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in one generation are normally small, differences with each generation overtime can become substantial changes in…

and other dangers. Fourth the origin of flower bear ovules within protective chambers called ovaries. Animals evolved from cells. One of the first cell was found 3.5 million years ago as a fossil. Animal over time transformed just like any other species. Through reproduction, animals create there young and overtime they evolve to adapt to their environment. (Simon, Dickey, & Reece,…
