Foraging networks and social tolerance in a cooperatively breeding primate (Callithrix jacchus)

María Fernanda De La Fuente, Cédric Sueur, Paul Garber, Júlio César Bicca-Marques, Antonio Souto & Nicola Schiel
Within-group competition over food resources can be a major cost of social living. In the wild, foragers are confronted with social (e.g. hierarchical rank) and ecological (e.g. food availability and distribution) challenges that affect their foraging decisions and feeding success. Exhibiting prosocial behaviors, such as tolerance at feeding sites, can benefit group members by developing affiliative social relationships, enhancing access to resources and maximizing fitness. We examined social tolerance at feeding sites in Callithrix jacchus,...

Changes in foraging mode caused by a decline in prey size have major bioenergetic consequences for a small pelagic fish

Global warming is causing profound modifications of aquatic ecosystems and one major outcome appears to be a decline in adult size of many fish species. Over the last decade, sardine populations in the Gulf of Lions (NW Mediterranean Sea) have shown severe declines in body size and condition as well as disappearance of the oldest individuals, which could not be related to overfishing, predation pressure, or epizootic diseases. In this study, we investigated whether this...
