Experimental evidence that social relationships determine individual foraging behavior
2015, Current BiologyCitation Excerpt :This suggests that mated partners influenced individuals’ foraging decisions, even if these decisions appear to be sub-optimal. Thus, although it is known that individuals may accept costs in order to gain potential benefits of foraging with others, such as predator defense and vigilance, discovery of new resources, and cooperation [17–21], birds in our experiment did so to maintain a single relationship. In the case of great tits, this relationship was the pair bond with their mate, yet this principle can apply to any type of social relationship.
Social foraging with partial (public) information
2014, Journal of Theoretical BiologyCitation Excerpt :Both models assume that group-size is known with certainty, and that all foragers enter and leave the patch simultaneously (i.e. the models do not consider changes in group-size during a foraging bout, and ignore potential dynamics due to war-of-attrition games (Sjerps and Haccou, 1994) or competitive interactions (Rands et al., 2004)). Under these assumptions, the importance of using partial public information can be used to understand decisions in social foraging groups where, for the sake of maintaining group cohesion, some members of the departing group are in fact leaving at a suboptimal time (Conradt and Roper, 2003; Livoreil and Giraldeau, 1997). We show that the use of partial, rather than full, public information entails only a slight fitness detriment; and suggest that it should be the preferred strategy when full information is costly.
The effects of facilitation and competition on group foraging in patches
2012, Journal of Theoretical BiologyCitation Excerpt :A major application of foraging theory has been in the context of “giving up densities” (density of resources at which individuals leave a patch) for assessing habitat quality (e.g. Brown, 1988; Valone and Brown, 1989). The difference in how extensively groups exploit a patch compared to a solitary forager can have important implications for analyzing giving up densities in the field (Livoreil and Giraldeau, 1997; Giraldeau and Caraco, 2000), highlighting the importance of empirical tests of the social patch model. The role of facilitation could further complicate these interpretations of field data.
Chapter 2 Social Foraging and the Study of Exploitative Behavior
2008, Advances in the Study of BehaviorCitation Excerpt :Although Parker (Parker, 1978; Parker et al., 1993) has already developed several models of competitive patch exploitation, there are still few experimental studies of the problem. In one case, Livoreil and Giraldeau (1997) have shown that when three spice finches exploit the same depleting seed patch, at least one individual will need to forage beyond its optimal departure time if it is to remain synchronized with the foraging of its flock mates. Patch exploitation time will also likely depend on the foragers' prey choices.
