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 ...
Additionally, 1193 amphibian species (16.4% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 3 ]
However, the zoospores are capable of chemotaxis, and can move towards a variety of molecules that are present on the amphibian surface, such as sugars, proteins and amino acids. [9] B. dendrobatidis also contains a variety of proteolytic enzymes and esterases that help it digest amphibian cells and use amphibian skin as a nutrient source. [10]
Otherwise known as the giant ditch frog, the amphibian is one of the largest frogs in the world, weighing in at over 2 pounds (almost 1 kilogram) with a length of up to 8 inches. At night, the ...

According to 2018 research, Madagascar would lose 60% of its species under 4.5 °C (8.1 °F), while Fynbos in Western Cape region of South Africa would lose a third of its species. Miombo Woodlands of South Africa would lose around 90% of their amphibians and about 86% of their birds if the warming were to reach 4.5 °C (8.1 °F). [1]
This is a list of the amphibian species recorded in Ghana. There are 80 amphibian species in Ghana, of which 2 are critically endangered, 6 are endangered, 4 are vulnerable and 10 are near-threatened. This list is derived from the Amphibiaweb Database & IUCN Redlist which lists species of amphibians and includes those amphibians that have ...
Of all evaluated amphibian species, 10% are listed as vulnerable. No subpopulations of amphibians have been evaluated by the IUCN. For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild".
