Mismatch between ectotherm thermal preferenda and optima for swimming: a test of the evolutionary pace hypothesis

Popis výsledku v původním jazyce

A continuing issue in evolutionary thermal biology is the mismatch between preferred body temperatures (Tpref) and optimal temperatures (Topt) for whole-animal performance. Using phylogenetic comparative analyses, I examined the hypothesis that a difference in the rates at which Tpref and Topt evolve causes the mismatch in a lineage of European newts. In a laboratory thermal gradient, newts maintained body temperatures that were on average 8°C below Topt for maximum swimming velocity. The lower boundaryof the Tpref range evolved faster than the mean Tpref, the upper boundary of the Tpref range, and Topt. The strong evolutionary co-variation between mean Tpref and its boundaries prevented the shift of mean Tpref away from Topt. This suggests that the variation in evolutionary rates has a limited potential to modify the disparity between thermal optima and preferenda.
