Wood Frogs Calling and Laying Eggs – Week of April 8

Mike Benard from Case Western Reserve University returned to the ESGR to collect wood frog (Lithobates sylvaticus) eggs this week (April 8-9).  He will raise the wood frogs in controlled laboratory conditions alongside wood frogs spanning a latitudinal gradient from North Carolina to Michigan to test for geographic variation in response to photoperiod and temperature.
