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 ...

We find that amphibians are the most threatened vertebrate class (40.7% of species are globally threatened). The updated Red List Index shows that the status of amphibians is deteriorating globally, particularly for salamanders and in the Neotropics. Disease and habitat loss drove 91% of status deteriorations between 1980 and 2004.
The mountain chicken frog, so-called as it tastes of chicken, is now endangered, in part due to human consumption, and was a major food choice of the Dominicans. [220] Raccoon, opossum, partridges, prairie chicken, and frogs were among the fare Mark Twain recorded as part of American cuisine. [221]
A number of causes are believed to be involved, including habitat destruction and modification, over-exploitation, pollution, introduced species, global warming, endocrine-disrupting pollutants, destruction of the ozone layer (ultraviolet radiation has shown to be especially damaging to the skin, eyes, and eggs of amphibians), and diseases like ...
Some animal-rights academics support this because it would break the species barrier, but others oppose it because it predicates moral value on mental complexity rather than sentience alone. [8] As of November 2019, 29 countries had enacted bans on hominoid experimentation; Argentina granted captive orangutans basic human rights in 2014. [9]
It belongs to a lineage believed to have given rise to the three living branches of amphibians - frogs, salamanders and limbless caecilians. Creature named for Kermit the Frog offers clues on ...
Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [36] (suspected of being one of the major causes of speciation [36]), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species.
