When the spring temperatures begin to rise and the snow recedes, the first warm rainy night of spring brings a chorus of spring peepers, wood frogs and mole salamanders. The spring migration happens sometime between mid March and April when evening temperatures rise above 40ºF as the amphibians move from the upland wooded areas to vernal pools and ponds to find suitable mates. Spotted salamanders are usually a secretive critter living under rocks, in seeps or underground in small damp burrows, so this is the night to be able to see them in large numbers. https://youtu.be/X9b02qycESc
This migration of yellow-spotted salamanders, Ambystoma maculatum, is a right of passage for some Binghamton University students. Devin DiGiacopo is a third year Phd student in Jessica Hua’s lab at Binghamton University and is researching how road salt affects spotted salamanders.
Orange-and-black wings fill the sky as NOVA charts one of nature’s most remarkable phenomena: the epic migration of monarch butterflies across North America. To capture a butterfly’s point of view, NOVA’s filmmakers used a helicopter, ultralight, and hot-air balloon for aerial views along the transcontinental route. This wondrous annual migration, which scientists are just beginning to fathom, is an endangered phenomenon that could dwindle to insignificance if the giant firs that the butterflies cling to during the winter disappear.
