News Articles Featuring Guilherme Becker

Unexpected diversity of light-sensing proteins goes beyond vision in frogs

Frogs have maintained a surprising diversity of light-sensing proteins over evolutionary time, according to a new study led by a Penn State researcher. Light-sensing proteins, called opsins, enable vision in sighted animals, and are responsible for many more biological functions like regulating circadian rhythms. The researchers explored the evolution of nonvisual opsins in frogs, finding that most modern species examined in this study retained a shocking number of these proteins.

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.
