In a Paradox, Good News for City Frogs

In a world rapidly losing its species diversity, amphibians have the highest rate of extinction among vertebrates. Although the usual culprits of habitat loss and human incursion play a major role, a fungus called Batrachochytrium dendrobatidis (Bd) that causes an often fatal skin disease in amphibians has played a major role in the decline or extinction of about…  More 

Ramped Up Risk for Frogs When Chinese Tallow Interacts with Climate Change

The timing of mating and egg-laying in many amphibians is directly related to temperature. Due to climate change, spring warming comes sooner in many areas, and a new study led by U.S. Forest Service researcher Daniel Saenz suggests that the changed timing of breeding could cause native amphibians such as the southern leopard frog and…  More 

Invasive Tallow Tree Lowers Frog Egg Survival

Numerous studies have addressed causes of the decline, but very few have looked at the effects of invasive plants. Dan Saenz, Southern Research Station (SRS) research wildlife biologist…  More 

Prescribed Fire in the Piney Woods

Effects on amphibians and reptiles Forest managers across North America use prescribed burning for many reasons—restoring ecosystem functions, improving wildlife habitat, reducing wildlife hazard, to name a few. Prescribed fire can have both beneficial and negative effects on specific plants and animals. Managers are increasingly sensitive to possible effects of fire on amphibians and reptiles…  More
