Amphibians in the US Caribbean, like the well-known coquí frog, are particularly vulnerable to human-caused climate change. Coquí frogs are represented by 17 species across Puerto Rico and US Virgin Islands and include several mountainous and coastal species that are threatened by extreme heat and drying, loss of coastal freshwater marshes through saltwater intrusion, or both. Over the past decade, the Southeast Climate Adaptation Science Center has invested in several scientific investigations to understand how global climate change is likely to affect the local climate of the US Caribbean and how sensitive different coquí species are to changes in local climate and habitat conditions in Puerto Rico. This project...

The Pacific Northwest is a hotspot for temperate amphibian biodiversity and is home to many species of salamanders and frogs found nowhere else on earth. Changing climatic conditions threaten habitat for many of these species and may also enhance the risk of disease and invasive species encroachment. State and federal wildlife agencies are in the process of evaluating these threats, but information is lacking. Wildlife managers need to know: the availability of suitable habitat under different climate scenarios; the vulnerability of at-risk amphibians to different diseases, and how climate change will affect that vulnerability; and the potential future spread of harmful invasive species like American bullfrogs,...
Abstract: Wetlands in the remote mountains of the western US have undergone two massive ecological “experiments” spanning the 20th century. Beginning in the late 1800s and expanding after World War II, fish and wildlife managers intentionally introduced millions of predatory trout (primarily Oncorhynchus spp) into fishless mountain ponds and lakes across the western states. These new top predators, which now occupy 95% of large mountain lakes, have limited the habitat distributions of native frogs, salamanders, and wetland invertebrates to smaller, more ephemeral ponds where trout do not survive. Now a second “experiment” – anthropogenic climate change – threatens to eliminate many of these ephemeral habitats...
