      The pattern of threats to vertebrate species in China differs strikingly from that in the United States (figure 1; see also table 2 in Wilcove et al). Differences in the frequencies of each of the five primary threat categories for vertebrate species in China versus the United States were significant (x 2 = , degree of freedom [df Cited by: ecosystems upon which endangered and threatened species depend. Although extinctions occur naturally, in the United States under the Endangered Species Act have been successful in preventing extinction for 99 percent of the species that are listed as endangered or threatened.

      It was a market-based agri-environment program that ran between and , which funded farmers to conserve threatened ecosystems on their property. Land managers were given contracts for up. Lange's metalmark is one of the most endangered species in the United States. It declined from some , in historic times to just in It improved a bit, but then declined to just 45 butterflies in Today the species is still on the knife edge of extinction, with about individuals remaining.

    An invasive species is a non-indigenous species (e.g. plants or animals) that adversely effect the habitats they invade. They can endanger indigenous populations by preying on them or by out-competing them for resources such as food.   Our living resources: a report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems by United States.

IUCN classifies ecosystems according to their risk of extinction, there are eight categories: Not evaluated, data deficient, least concern, near threatened, vulnerable, endangered, critically endangered and collapse.

In this list, all of the ecosystems are endangered except the last one - the Aral Sea - already collapsed and therefore. significant losses of biodiversity at the ecosystem level in the United States.

The most substantial losses were summarized by listing ecosystems as critically endangered (>98% decline), endangered (% decline), and threatened (% decline). We identified more than 30 critically endangered, 58 endangered, and more than 38 threatenedFile Size: 2MB. Get this from a library.

According to the International Union for Conservation of Nature (IUCN), more t species are endangered at the moment. The United States Fish and Wildlife Service only recognize a small number of these species — somewhere between and species.

The IUCN releases its criteria for a new Red List of Ecosystems, which measures an ecosystem's risk of collapse. Included are 20 case studies. ENDANGERED SPECIES AND BIODIVERSITY••• Although projections vary, reliable estimates are that about 20 percent of Earth's species may be lost within a few decades, if present trends go unreversed.

These losses will be about evenly distributed through major groups of plants and animals in both developed and developing nations, with special concerns over tropical forests. Endangered and Threatened Species ofthe Southeastern United States (Red Book).

If we all work together, we can continue to share the earth with these fascinating and. The IUCN Red List of Ecosystems (RLE) is a global framework for monitoring and documenting the status of was developed by the International Union for Conservation of Nature for biodiversity risk main objectives are to support conservation, resource use, and management decisions by evaluating all the world's ecosystems by   The book's 11 chapters include arguments for the importance of biodiversity conservation, descriptions of the techniques used for biodiversity inventories, summaries of the distribution and status of biodiversity in the United States, an overview of major threats to imperiled species (drawn largely from Wilcove et al.

[]), and outlines of Cited by: 2. The Laysan teal (Anas laysanensis) has the most restricted range of any duck species and is especially vulnerable to extinction because of its small population size and vulnerability to climate species was believed to be endemic to one island until new sub-fossil evidence and ancient DNA-testing revealed Laysan teal were widespread across the Hawaiian archipelago.

There are many endangered animals and they come in all shapes and sizes. Ninety-nine percent of the earth's creatures have become extinct.

Just in the United States more than a dozen insects, mostly butterflies are on the endangered species list, along with over 50 species of fish, reptiles and amphibians, and over mammals. (World Book. The Endangered Species Act of (ESA or "The Act"; 16 U.S.C.

Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon Enacted by: the 93rd United States Congress.

The natural ecosystems of the United States have been significantly altered. We found endangered ecosystems at several levels of classification and at many spatial scales.
