It was the subject of scientific research until populations suddenly crashed in 1987 and it had disappeared completely by 1989. [7] Other species at Monteverde, including the Monteverde harlequin frog (Atelopus varius), also disappeared at the same time. Because these species were located in the pristine Monteverde Cloud Forest Reserve, and ...
One attempt was made to protect a wide variety of frogs from the disease by using the bacterium Janthinobacterium lividium that produces a chemical against the infections; however, the skin of Panamanian golden frogs was unsuitable for the bacterium used. [20] The San Diego Zoo started a conservation effort and received their first frogs in ...
This only happened in fish-free lakes, because only those had enough frogs and enough genetic variation to evolve resistance. So in 2006 Knapp and other researchers set about to see if the frog ...

A type of leaf-eating langur that has an unusually long and bushy tail with white hips. It is also one of the most endangered primates in the world. Only about 300 Delacour's langurs are alive today, and experts fear they could be completely extinct if the current rate of decline continues.
Pine Barrens tree frogs are rarely encountered in sites where nonnative amphibians, such as bullfrogs, and nonnative fish are present, suggesting that they are poor competitors. As a consequence of this, D. andersonii populations found in or near developed and agricultural areas are believed to be the most at risk due to the greater presence of ...
Western chorus frogs live in a variety of different habitats, but areas of more permanent water increase the risk of predation on eggs and/or tadpoles. To compensate for this, chorus frogs stick to mostly ephemeral freshwater areas, such as marshes, river swamps, meadows, grassy pools, and other open areas found in mountains and prairies.
