THE CONCEPT OF SPECIES What are species? Species are the basic taxonomic units of biological classification. This grouping of organisms of "like kind" into discrete and stable units has been traced at least from the time of Plato and Aristotle. The term derives from the Latin "specere" (to look at‚ to behold)‚ with the meaning of "kind‚“ "quality‚" "appearance‚" "shape‚" or "a peculiar sort.“ In the past‚ species were classified according to their shape. Carl Linnaeus (1707-1778)‚ the

Endangered Species Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals‚ birds‚ reptiles‚ amphibians‚ and (many people do not consider them) plants .CAUSES OF EXTINCTION Millions of years before humans‚ extinction of living things was linked to geological and climate‚ the

Topic: Endangered Species Issue Question: Should Endangered Species be Protected? Since the appeared of the first life on this planet‚ numerous species come and go‚ rendered extinct by natural changes in physical and biological conditions. Because extinction is a natural part of the order‚ if there are many other species still exist‚ some people might wonders why or what so unique about the endangered species that large sum of money and effort is spent in order to save and restore them (Why

Endangerment is a broad issue‚ one that involves the animals as well as the environments where they live and interact with one another. In order to solve or even slightly elevate this problem‚ every aspect must be studied. So exactly what could cause the endangerment of animals? There are several factors of which only a few will be discussed. One of the main aspects is that of habitat destruction. Of course our planet is continually changing‚ causing habitats to be altered and modified‚ but

4/10/11 James Ross Aftermath of the Invasion The introduction of invasive species into new environments is a problem that plagues the entire planet. Humans have been moving species around the world and introducing them into new environment for millennia. Many introduced species become invasive‚ disrupting ecosystems and threatening the survival of other species‚ sometimes driving them to extinction. Some invasive species‚ including some insects‚ seem to thrive particularly well in already degraded

Invasive species pose a threat to the continued survival of the native plant life‚ at camp catalpa. The two most prevalent invasive species are the Bush Honeysuckle and the Roughleaf Dogwood. Several species have been negatively impacted by the continued presence of the invasive Bush Honeysuckle and Roughleaf Dogwood. The Bush Honeysuckle produces a toxin‚ which is released into the soil that inhibits the growth of other species. Bush Honeysuckle and Roughleaf Dogwood are shade tolerant species. There

January 9‚ 2013 Foreign Invaders Invasive species are groups of organisms that are unnaturally occurring to an area. When introduced‚ they can cause economic and physical harm to humans and ecosystems. The importing‚ legally and illegally‚ of invasive species into our society is not only harmful to our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new ecosystems is caused by a number
