Chytridiomycosis infection
Fungal disease caused by
Batrachochytrium dendrobatidis
(Bd)
Bd
is a fungus that lives in the gut of animals
Infects frogs, and has caused decline in over 500 amphibian species
Causes skin disease in the frogs, which is often fatal

Natural history
Bd fungus does not survive in warm climates (> 30 degrees)
Warm host climate also reduces lethality
Idea
If we can heat frogs, maybe we can reduce the impact of this infection
Experiment setup
Frogs separated into two classes: shaded and unshaded (heated)
Artifical refugia placed into each mesocosm (replicate)
Measure infection load and mortality
