Many of the causes of amphibian declines are well understood, and appear to affect other groups of organisms as well as amphibians. These causes include habitat modification and fragmentation, introduced predators or competitors, introduced species, pollution, pesticide use, or over-harvesting. However, many amphibian declines or extinctions ...
Most amphibian species are also threatened by native habitat loss, [41] and some species are now only breeding in modified habitat. [42] Endemic organisms with limited ranges are most affected by habitat destruction, mainly because these organisms are not found anywhere else in the world, and thus have less chance of recovering.
However, many of the causes of amphibian declines are still poorly understood, and the topic is currently a subject of ongoing research. Modeling results found that the current extinction rate of amphibians could be 211 times greater than the background extinction rate. This estimate even goes up to 25,000–45,000 times if endangered species ...
From the African tree frog to the tiger salamander, there are thousands of species of amphibians that can be found scattered all over the world. Amazing Amphibians: A 5-Day Unit Plan for Kids Skip ...
When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
A 2019 Science review assessed that chytridiomycosis was a factor in the decline of at least 501 amphibian species during the past 50 years, of which 90 species were confirmed or presumed to have gone extinct in the wild and another 124 had declined in numbers by more than 90%. [37]
Amphibian Ark is an organization that was formed to implement the ex-situ conservation recommendations of this plan, and they have been working with zoos and aquaria around the world, encouraging them to create assurance colonies of threatened amphibians. [178] One such project is the Panama Amphibian Rescue and Conservation Project that built ...
Habitat restoration is a subset of habitat conservation and its goals include improving the habitat and resources ranging from one species to several species [35] The Society for Ecological Restoration's International Science and Policy Working Group define restoration as "the process of assisting the recovery of an ecosystem that has been ...
