Drought may drive deadly amphibian disease, researchers find
Pumpkin toadlets are in trouble. Progressively severe droughts are disrupting the microbiomes of the thumbnail-sized orange frogs, potentially leaving them vulnerable to a deadly fungal disease, according to a new study by an international research team.

Vaccine against deadly chytrid fungus primes frog microbiome for future exposure
A human's or animal’s microbiome — the collection of often beneficial microorganisms, including bacteria and fungi, that live on or within a host organism — can play an important role in the host’s overall immune response, but it is unclear how vaccines against harmful pathogens impact the microbiome.

Habitat split may impact disease risk in amphibians and other vertebrates
Habitat split is a common event in the environment that occurs when different classes of natural habitats, such as forests and water, are disconnected.
