Many species today are impacted by threats from changing environments. These threats can pose a great amount of harm to a specific species‚ which in turn‚ can ultimately cause it to be endangered. A species is considered endangered when a threat is relatively high and a population is rapidly declining in size. One of the most effective ways to identify an endangered species is through acknowledging habitat loss‚ introduced species‚ pollution‚ and overconsumption. This paper will investigate two endangered

Invasive Species what are they? An invasive species is a plant‚ animal‚ or fungi that is not native to a certain area. These species can cause great damage to an ecosystem‚ human economy‚ human health‚ and other species that are native to the area. European Carp Troubles in Australia?!

How the European Carp arrived or when is unclear but the effects are noticeable

"Human activity is putting such strain on the natural functions of Earth that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted‚" it said. Ten to 30 percent of mammal‚ bird and amphibian species were already threatened with extinction‚ according to the assessment‚ the biggest review of the planet’s life support systems.

Old-growth/ Primary -uncut/ regenerated forest that has not been seriously disturbed by human activities/ natural disasters for 200 years or more - reservoirs of biodiversity (provide ecological niches for a variety of wildlife species) 2.

A Study on Mangrove Ecosystems Ecosystems are very delicate mechanisms‚ and the mangroves are particularly fragile. Mangroves rely on a multifaceted interface comprising of their land position‚ rainfall hydrology‚ sedimentation‚ subsidence‚ sea level‚ storms‚ pest-predator relationships and many other biogeochemical and environmental factors. Any one of these interactions becoming skewed or unsettled can lead to a rapid decline in the numbers of the mangroves in any environment. A relatively simple

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

Amphibians are becoming a vanishing species. There are a number of causes for them dieing. But the most recent and worst cause has been discovered. It is responsible for killing off our amphibians. They are dieing by the thousands. They were able to survive and hold on through past extinction spasms‚ surviving even when 95 percent of other animals died out. They even stayed alive when the dinosaurs disappeared. If amphibians could live longer than dinosaurs‚ then why are
