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

altered and modified‚ but these tend to happen at a gradual pace. This allows most species to adapt to the changing environment‚ where only a slight impact may take place. However‚ when changes occur at a fast pace‚ there is little or no time for an individual species to react and adjust to the new circumstances. This cause disastrous results‚ and for this reason‚ rapid habitat loss is the primary cause of species becoming endangered. Nearly every region of earth has been affected by human activity

A wetland is a land area that is saturated with water‚ either permanently or seasonally‚ such that it takes on the characteristics of a distinct ecosystem.[2] Primarily‚ the factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation that is adapted to its unique soil conditions. Wetlands consist primarily of hydric soil‚ which supports aquatic plants.[3][4] The water found in wetlands can be saltwater‚ freshwater‚ or brackish.[4] Main wetland types

This lack of precipitation loosely illustrates what encompasses the desert ecosystem. Although there are many cold deserts around the globe‚ for the purpose of analysis‚ the focus of this paper will be hot desert ecosystems. The extreme heat of the day in some deserts can reach above 120 degrees and drop down below 32 degrees (National Geographic‚ 1996-2013). These temperature extremes

Endangered species are those considered to be at risk of extinction‚ meaning that there are so few left of their kind that they could disappear from the planet altogether. Endangered species are threatened by factors such as habitat loss‚ hunting‚ disease and climate change‚ and usually‚ endangered species‚ have a declining population or a very limited range. The current rate of extinction is thought to be far greater than the expected natural rate‚ with many species going extinct before they have

Loss of Species Every year a new species gets placed on the endangered species list‚ extinction is a natural process but due to human activity there has been a rapid decline in the wild species population. Loss of habitat or alteration‚ hunting‚ introduction of foreign species‚ and disease are major culprits in the extinction rate. The protection of species is an important element to the survival of biodiversity as well as human sustainability. The loss of a species means humans will lose out

An explanation of the key abiotic components of the ecosystem? That are non-living chemical and physical factors in the environment‚ which affect ecosystems. A good example is that a lot of small bushes and shrubs would not be able to live here because all the really tall trees would block most of the sunlight causing a lack

African Ecosystem African Ecosystem The individual organism being a lion on the African wilderness is an endanger species that struggles in life to feed it self‚ and its pack members. In Africa there are animals that need to eat other animals to survive‚ and the lion is on the top chain. The producers of these ecosystems are plant that animals consume to survive in the harsh environment that Africa percents to this animals. The consumers are those animals that eat plants and animals to survive

Biodiversity has been on the decline over the past century and the background rate has been mostly accelerated by the humans. Considerable damage has already been done. Possible solutions have been discussed and categorising species according to how in danger they are is one of those solutions. Below are some of the threatened organisms in different continents around the world. TABLE OF CONTENTS Africa Mammals Birds Reptiles Amphibians Fishes Asia Mammals Birds Reptiles

coral reef being home to one-third of fish species‚ humans have severely impacted the fish species by destroying their homes. Overexploitation is a huge risk‚ and this became very evident when the wolf population in Yellowstone was wiped out. Every wolf was hunted and killed in Yellowstone‚ and once the wolves were gone‚ the ecosystem became very unbalanced and many species started to either die out or be overpopulated. As for methods to help sustain species‚ core reserves and wildlife corridors are
