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.
The cane toad (Rhinella marina) has been known to survive 24 years in captivity, and the American bullfrog (Rana catesbeiana) 14 years. [171] Frogs from temperate climates hibernate during the winter, and four species are known to be able to withstand freezing during this time, including the wood frog (Rana sylvatica). [172]
[21] [22] The bullfrog often escapes captivity and can establish feral populations where it may introduce the disease to new areas. [8] It has also been shown that B. dendrobatidis can survive and grow in moist soil and on bird feathers, suggesting that B. dendrobatidis may also be spread in the environment by birds and transportation of soils ...

Aquatic biomonitoring is the science of inferring the ecological condition of rivers , lakes , streams , and wetlands by examining the organisms (fish, invertebrates, insects, plants ...
Once released into the aquatic environment, zoospores travel less than 2 cm (0.8 in) within 24 hours before they encyst. [21] The limited range of B. dendrobatidis zoospores suggest some unknown mechanism exists by which they transmit from one host to the next, [21] which can involve the pet trade, and especially the American bullfrog.
