Abstract
Foraging theory has been widely used to understand patterns associated with obtaining resources and the optimal cost-benefit relationship between forager and resource. However, many analytical theoretical models do not consider the influence of social groups on forager strategy. We analyzed strategies for obtaining resources from two perspectives: individual and social. For the first, we tested hypotheses that addressed whether individual strategies followed the predictions of classic models of foraging theory. In the second approach, we investigated potential social influences on resource-obtaining strategies. Our results suggest that regardless of the strategy adopted by the forager (specialist or generalist), environmental factors, such as abundance, regulated success in obtaining resources. However, we observed that specialists had a greater advantage relative to generalists when resources were abundant. We also observed that forager decision-making was related to the social context of the individual forager, which influenced their strategies.

Ethics declarations
For our initial research, authorization was requested from the Research Ethics Committee (REC) of the Federal University of Pernambuco (UFPE) in accordance with Resolution no. 466/2012 of the National Health Council. With this authorization, to meet the requirements of the resolution, the research objectives were explained to the beekeepers involved in the study before they signed an Informed Consent (IC) to authorize the use of forms and allow interviews. Because the study region is within an Environmental Protection Area (Araripe-EPA), authorization for the survey was obtained from the ICMBio through the Authorization and Information on Biodiversity System (SISBIO) under no. 38021–1.
