Cryo-freezing amphibian sperm can result in smaller tadpoles and toads — a discovery that may have implications for future captive populations intended for eventual reintroduction. Comparing toads raised through cryo-freezing...

Restored cranberry farm environments don’t immediately attract large numbers of native amphibians and reptiles or initially promote species diversity of native amphibians and reptiles, according to preliminary results presented in...

A new deadly contagious frog virus made up of genes from Asia and America has the ability to rapidly wipe out whole amphibian populations. This ranavirus strain could already be...

Researchers have created the most comprehensive map yet of the spread of the deadly chytrid fungus pathogen. The map lays out the locations and timeframes of appearances of the pathogen...

“Introduced species can provide this natural experiment of what happens when you toss species in a completely different climate — can they survive or not?” said John Wiens, a professor...

They may be cold-blooded, but some amphibians induce feverish temperature changes to help their immune systems fight the deadly ranavirus. “Amphibians are ectotherms, so they can’t regulate their temperature” independently...

Populations of Arizona toads are standing their ground despite the generalist nature of their cousins downstream. “I call them the ‘trash can toad’” because they will breed in just about...

Forests on land previously used for agriculture or grazing, known as secondary forests, may be less suitable for long-lived salamanders. While new research shows that large numbers of vernal pools...

Scientists who want to find out which frog populations are more likely to contract the deadly ranavirus, which affects amphibians and reptiles globally, recently turned to frogs’ skin. Studying European...

For frogs, a stressful early life as a tadpole can lead to long-term fitness consequences in adulthood. “Even though you have this huge change in body morphology through metamorphosis, that...
