Thermal tolerance in Drosophila: repercussions for distribution, community coexistence and responses to climate change

José M. Alruiz, Ignacio Peralta-Maraver, Francisco Bozinovic, Mauro Santos & Enrico L. Rezende
Here we combined controlled experiments and field surveys to determine if estimates of heat tolerance predict distributional ranges and phenology of different Drosophila species in southern South America. We contrasted thermal death time curves, which consider both magnitude and duration of the challenge to estimate heat tolerance, against the thermal range where populations are viable based on field surveys in an 8-yr longitudinal study. We observed a strong correspondence of the physiological limits, the thermal...
