ENDANGERED SPECIES Introduction An endangered species is a population of organisms which is at risk of becoming extinct because it is either few in numbers‚ or threatened by changing environmental or predation parameters. The International Union for Conservation of Nature (IUCN) has calculated the percentage of endangered species as 40 percent of all organisms based on the sample of species that have been evaluated through 2006.Many nations have laws offering protection to

The species richness is when we talk about the actual number of species in a community. For example‚ if you go to a bottom ground forest you might see only sugar maple. Therefore‚ the species richness is only 1. Shannon Index measures species diversity too‚ but takes into account species evenness. Species evenness is when the relative abundance of the species in that community are more similar to each other. So by knowing that you have more similar species‚ this allows you to more accurately determine

The Asiatic lion (Panthera leo persica)‚ also known as the Indian lion‚ is a lion subspecies that exists as a single isolated population in India’s Gujarat State. It is listed as Endangered by IUCN based on the small population size.[1] The lion population has steadily increased in Gir Forest National Park‚ more than doubling from a low of 180 individuals in 1974 to a level of 411 individuals consisting of 97 adult males‚ 162 adult females‚ 75 sub-adults‚ and 77 cubs as of April 2010.[3] The Asiatic

Coral reefs are the home to more species than any other marine ecosystem‚ making them some of the most treasured and diverse ecosystems on the planet. They provide revenue for local communities by forming nurseries for fish‚ provide a destination for diving tours and fishing trips‚ break the power of waves to create a buffer that prevents erosion‚ property damage‚ and inundation‚ and protect the wetlands that line the coast‚ as well as ports and harbors. Many medicines are also now being developed

1. Decodable Text * There are five levels of decodable text‚ ranging from highly decodable to minimally decodable. Highly decodable books use one-syllable and one-vowel-sound words‚ such as “cat‚” “fun” or “sit.” These might also use some short sight words‚ such as “a‚” “an” and “the.” Very decodable text still uses simple words‚ but those words may now have an extra letter or use blends that the students are learning in class‚ such as “this‚” “such” or “that.” Decodable text adds more of

(Federation‚ 2000) The geology of Southern Florida‚ has a warm and wet subtropical climate that provides conditions that help the large marshland ecosystem flourish. Layers of porous and permeable limestone create water bearing rock and soil that effect the climate‚ weather and hydrology of Southern Florida.
