1. Rapid evolution of physiological traits in response to novel thermal environments has rarely been demonstrated in natural populations. 2. We studied the temperature dependence [thermal performance curves (TPCs)] of larval feeding rate for two populations each of Colias eurytheme and Colias eriphyle in North America that occur over a range of elevations and climates. Using historical data for two of the populations, we assessed changes over time in both air temperatures and TPCs for larval… CONTINUE READING
