Responding to a Variable Environment: Home Range, Foraging Behavior, and Nest Relocation in the Costa Rican Rainforest Ant Aphaenogaster araneoides

摘要: We studied how the tropical wet forest ant Aphaenogaster araneoides adjusted its home range and foraging behavior in response to changes leaf litter food environments. decoupled abundance availability by creating a factorial treatment design including removal supplementation. Leaf caused decrease number of trips but an increase their duration. Over 2-week experimental period, about half colonies relocated nests. found strong effect nearest neighbor distance upon areas after they In summary, short-term manipulations resources resulted area behaviors that differed depending nest relocation competitive environment.
