Abstract
NOTICE: Following the publication of the related research article by Costa-Pereira & Pruitt [1], the journal was made aware of potential problems with the associated raw data collected by co-author, Jonathan Pruitt. An investigation into the data detected duplicated values and as such, results drawn from these data cannot be considered reliable. A link to the retraction is available here: https://royalsocietypublishing.org/doi/abs/10.1098/rsbl.2020.0588

Generalist populations are often composed of individuals each specialized on only a subset of the resources exploited by the entire population. However, the traits underlying such niche variation remain underexplored. Classically, ecologists have focused on understanding why populations vary in their degree of intraspecific niche variation, with less attention paid to how individual-level traits lead to intraspecific differences in niches. We investigated how differences in behavior, morphology, and microhabitat affect niche variation between- and within-individuals in two species of spider Anelosimus studiosus and Theridion murarium. Our results convey that behavior (i.e., individual aggressiveness) was a key driver of intraspecific trophic variation in both species. More aggressive individuals capture more prey, but particularly more Coleoptera, Hymenoptera, and Diptera. These findings suggest that behavioral traits play a critical role in determining individuals’ diet, and that behavior can be a powerful force in driving intraspecific niche variation.
