The golden toad of Monteverde, Costa Rica, was among the first casualties of amphibian declines.Formerly abundant, it was last seen in 1989. Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world.
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature. More than 2,000 species of ...

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]
A shocking new report on global biodiversity is detailing what it calls "a catastrophic decline" in wildlife populations ahead of a major international conference on biodiversity.
Reasons cited include population reduction, small population size and decline, extinction probability analysis, very small or restricted population numbers and a restricted geographic range. Why ...
According to a study by the Australian National University, the Bd fungus has caused the decline of 501 amphibian species—about 6.5 percent of the world's known total. Of these, 90 species have been entirely wiped out and another 124 species have declined by more than 90 percent, and the odds of the affected species recovering to a healthy ...
