Conservation Biology and Biodiversity
Conservation biology is the scientific study of the environment to preserve and maintain the Earth’s biodiversity and an interdisciplinary focus on sociology, philosophy, economics, and environmental law as they relate to the way in which humans practice conservation. This is science particularly concerned with resource management and the intrinsic value of all organisms. Biodiversity in simplest terms is life in all its forms that ranges from microorganisms, fungi, vertebrates, invertebrates, genes, species, and even ecosystems (Hunter & Gibbs, 2007). Although conservation and biodiversity differ in meaning, the two are closely related because biodiversity depends on conservation.
Threatened, Endangered, and Extinct Species
A species is a group of interbreeding populations isolated from other groups. Although some species may look almost identical, the possibility of interbreeding may not always be exist. In some cases, some species may breed with different ones and produce fertile or infertile hybrids. On Earth, the species range varies from approximately two million known species, and 12 million yet to identify. The difference between threatened, endangered, and extinct species is defined by the World Conservation Union (IUCN) Red List. Threatened species are species that depend on conservation to maintain their populations stable. An example of a near threatened species is the tusked frog because it is significantly decreasing in population at a rate less than 30%. Threats to this species of frogs are loss and degradation of its environment through agricultural and urban expansion, as well as weeds and predatory fish ("Species reports," 2007). A species considered to be endangered is rare, but has a significant decline in population. The Talaud Fruit Bat is listed as endangered because its extent of existence is less than 5,000...
