Interspecific and interpopulation variation in individual diet specialization: Do environmental factors have a role?

open access: yesEcology, Volume 101, Issue 8, August 2020., 2020
Abstract Individual diet specialization (IS) has important community‐ and population‐level implications and its ecological drivers are actively investigated. Here, to test the hypothesis that local environmental conditions may influence IS in wild populations, we analyzed the stomach contents of 395 individuals from eight populations of five allopatric
