By hightailing it to nearby ponds and shallow waterways, frogs and salamanders have – until now – had a way to evade exotic trout introduced to the West’s high-mountain lakes for recreational fishing. A warming climate, however, will dry up some of the places where amphibians and their young have found refuge. Researchers in the May 1 issue of Frontiers in Ecology and the Environment write about this challenge and a novel combination of tools that could help land managers, biologists, fishing enthusiasts and other citizens weigh where amphibians are in the most need of help and guide plans for possible fish removals from selected lakes.

New ocean acidification research published in late April shows a strong correlation between current ocean conditions and the dissolution of sea butterfly shells. Sea butterflies–or pteropods–play an important role in the marine food web, providing a food source for higher-level predators like salmon. The study focuses on the California Current, which stretches along the entire west coast of the United States and is a key driver of how our nearby marine ecosystems take shape and function.
