Batrachochytrium dendrobatidis is a pathogen primarily found in amphibians, and it’s presence can have devastating effects on amphibian populations. Batrachochytrium dendrobatidis is responsible for causing Chytridiomycosis, or chytrid, in amphibians all across the world in response to rising global temperatures. Chytrid fungus thrives in rising temperatures, and it attacks the keratinized layer of the epidermis, causing it to thicken. This is devastating to the amphibian populations because they must keep their skin moist through mucous membranes in order to respirate properly.

My research question is: How does the fluctuation of temperatures across the globe affect the growth of Batrachochytrium dendrobatidis in amphibian populations, and how do amphibians combat this pathogen? Experiments have been conducted on how climate change correlates with chytrid fungus growth, and limited research has been done to show how these amphibians combat it. There is limited evidence that amphibians are able to avoid this pathogen, but there has been some research insinuating that amphibians may travel to deeper and cooler waters to potentially prevent the accessibility of Batrachochytrium dendrobatidis. Batrachochytrium dendrobatidis depletes amphibian populations across the globe, and it is very applicable to them and their environments. If the temperatures continue to rise, then this pathogen could run rampant through the amphibian populations leading to mass extinction.
