Food sharing is often evolutionarily puzzling, because the provider's benefits are not always clear. Sharing among kin may increase indirect fitness [1], but when non-kin are involved, different mechanisms were suggested to act. Occasionally, "tolerated theft" [2, 3] is observed, merely because defending a resource is not cost effective. Sharing may also be explained as "costly signaling" [4, 5], where individuals signal their high qualities by distributing acquired resources, as has been… Expand
Producer–scrounger relationships in yellow-bellied marmots 0003-3472/© 2020 The Association for the Study of A When social animals forage together, they may engage in frequency-dependent strategies either asExpand
Effect of group size on producer–scrounger strategies of Wistar rats
The distribution of search responses of Wistar rats relative to the size of the group was assessed and the relative frequency of producing and scrounging associated activities correlated with the time spent consuming food procured by each activity. Expand
Sick Bats Stay Home Alone: Social distancing during the acute phase response in Egyptian fruit bats (Rousettus aegyptiacus)
Together, these sickness behaviors demonstrate a strong, integrative immune response which promotes recovery of infected individuals while protecting their group members from transmission of pathogens, and at the same time, reducing spillover events outside the roost. Expand
Fruit bats adjust their foraging strategies to urban environments to diversify their diet
Bats foraging in settlements diversified their diet in comparison to rural bats, as was also evident from their choice to often switch fruit species, and how such mobile mammals might exploit the new urban fragmented environment that is taking over the authors' landscape. Expand
Decision making in foraging bats
This review examines the different factors influencing the decision process of bats during foraging, including the position and quality of food items, the location of conspecifics, and the bat's movement history. Expand


Do females use their sexual status to gain resource access? Investigating food-for-sex in wolves and dogs
This study demonstrates that the food-for-sex hypothesis plays a part in intersexual food sharing in canids, and highlights the role of females in the interaction. Expand
Social benefits of non-kin food sharing by female vampire bats
Results indicate that a bat can expand its network of possible donors by helping non-kin, suggesting the possibility of alternative responses to a partner's inability to reciprocate. Expand
Food sharing in vampire bats: reciprocal help predicts donations more than relatedness or harassment
The hypothesis that food sharing in vampire bats provides mutual direct fitness benefits, and is not explained solely by kin selection or harassment, is supported. Expand
Meat sharing among the Gombe chimpanzees: harassment and reciprocal exchange
Sharing food with nonkin is detrimental to a food donor's fitness, unless it is matched by compensatory benefits. I evaluated two explanations for nonkin meat sharing among wild chimpanzees, PanExpand
Non-kin cooperation in bats
It is explained how cooperative investments can occur in several situations and are particularly evident in food sharing among common vampire bats and alloparental care by greater spear-nosed bats. Expand
Food sharing and reciprocal obligations among chimpanzees
Food sharing has been proposed as the propeller of hominid evolution, particularly of the development of systems of mutual social obligation. Yet, food sharing in our closest relative has never beenExpand
Reciprocal food sharing in the vampire bat
It is shown that food sharing by regurgitation of blood among wild vampire bats (Desmodus rotundus) depends equally and independently on degree of relatedness and an index of opportunity for recipro cation. Expand
Social bonds facilitate cooperative resource sharing in wild chimpanzees
It is concluded that the emotional connection inherent in social bonds was a key factor determining sharing patterns, with the oxytocinergic system potentially facilitating long-term cooperative exchanges in chimpanzees. Expand
Food Sharing Among Ache Foragers: Tests of Explanatory Hypotheses [and Comments and Reply]
This paper aims to describe and explain aspects of food sharing among Ache hunter-gatherers of eastern Paraguay. Food sharing has been widely held to be a fundamental feature of the hunting andExpand
Wild Chimpanzees Exchange Meat for Sex on a Long-Term Basis
It is strongly suggested that wild chimpanzees exchange meat for sex, and do so on a long-term basis, as well as if the direct nutritional benefits that women receive from hunters in foraging societies could also be driving the relationship between reproductive success and good hunting skills.
