Sunny-side up: ontogenetic variation in egg mass temperatures of the wood frog Rana sylvatica by Ryan Calsbeek, Ava Calsbeek, Isabel Calsbeek

“…Here, we explore finer scale spatial variation within egg masses of the wood frog Rana sylvatica, one of the earliest amphibians to breed during the North American spring. We compared peripheral and core temperatures of egg masses that were exposed either to 1) ambient sunlight from above, or 2) sunlight reflected by a mirror from below. …”
