Illustration and schematic diagram showing how optimal patch residence time will change in response to patch quality according to the MVT. (a) Consider an animal foraging in an
environment where prey patches are heterogeneously distributed.

Partial regression plots (i.e. the relationship between the response variable and a predictor, with the other predictors held constant [20]) from a linear mixed model (dive duration = dive depth +
dive-scale patch quality + bout-scale patch quality) with bi...
