A predator's functional response determines predator–prey interactions by describing the relationship between the number of prey available and the number eaten. Its shape and parameters fundamentally govern the dynamic equilibrium of predator–prey interactions and their joint abundances. Yet, estimates of these key parameters generally assume stasis in space and time and ignore the potential for local adaptation to alter feeding responses and the stability of trophic dynamics. Here, we evaluate if functional responses diverge among populations of spotted salamander (
We evaluated prey eaten versus prey given in larvae raised in a common garden experiment from different populations.
Column names: rep - temporal replicate; pred.risk - high or low marbled salamander predation risk in natal pond; cue - with or without chemical cues from marbled salamanders (AMOP); vase - container number; family - sibship number (egg mass); food.given - number of Daphnia provided initially; food.eaten - number of Daphnia eaten after 24 hours; wt - larval wet mass in mg.
