Calhoun speaks to Seacoastonline about ‘Big Nights’ for migrating frogs, salamanders
Aram Calhoun, professor of wetland ecology at the University of Maine, spoke with Seacoastonline about the spring phenomenon of the “Big Night” migration of amphibians to vernal pools. Calhoun said that some species of amphibian travel hundreds of feet, some travel miles, and that she has tracked them over mountain tops as they leave vernal pools after breeding and migrate to summer refugia.
