Virus causes unprecedented decline in tree frog population.

In a recently published article in the journal Biodiversity and ConservationScientists from Unicamp and the Federal University of Paraná (UFPR) have linked the massive decline of a monkey frog population to ranavirus infection. This is a virus that spreads rapidly among amphibians, reptiles, and fish, resulting in a high mortality rate, but until now it had never been identified as the cause of mortality events in native Brazilian species, whether in frog farms or in the wild. Before the publication of the study, researchers had only observed mass mortality caused by this virus in invasive species, such as the bullfrog and tilapia.
