Global warming is also causing an increase in diseases among amphibians. Considering that the Tropical Andes is recorded to have the most amphibians, some restricted to this location, diseases could decrease the diversity greatly. Another factor is that 400 of the amphibian species are already threatened. These deadly fungi have actually been linked to the extinction of dinosaurs. One chytrid fungus that is infecting amphibians is the batrachochytrium dendrobatidis. This fungus will impair the amphibian's skin and reduce its ability to absorb. One example of an amphibian in the Tropical Andes is the genus Atelopus, with 56 of the species Critically Endangered. Due to increase in temperature, the fungus has the ability to spread rapidly and thrive on living amphibians.
