Size, sex and individual‐level behaviour drive intrapopulation variation in cross‐ecosystem foraging of a top‐predator

JC Nifong, CA Layman… - Journal of Animal Ecology, 2015 - Wiley Online Library
Large‐bodied, top‐predators are often highly mobile, with the potential to provide important

Different ecological conditions support individual specialization in closely related, ecologically similar species

CS Cloyed, PK Eason - Evolutionary Ecology, 2016 - Springer
Individual generalist predators often have more specialized diets than their populations do.
Individual specialization (IS) is influenced by ecological opportunity, intraspecific …

Individual foraging specialization: niche width versus niche overlap

BL Sargeant - Oikos, 2007 - Wiley Online Library
A recent review of individual specialization suggests it is widespread and has important

High intraspecific variability in the functional niche of a predator is associated with ontogenetic shift and individual specialization

T Zhao, S Villéger, S Lek… - Ecology and …, 2014 - Wiley Online Library
Investigations on the functional niche of organisms have primarily focused on differences
among species and tended to neglect the potential effects of intraspecific variability despite …

Intrapopulation niche partitioning in a generalist predator limits food web connectivity

M Quevedo, R Svanbäck, P Eklöv - Ecology, 2009 - Wiley Online Library
