Social foraging and dominance relationships: the effects of socially mediated interference

摘要: In socially foraging animals, it is widely acknowledged that the position of an individual within dominance hierarchy group has a large effect upon its behaviour and energetic intake, where intake subordinates can be reduced through mediated interference. this paper, we explore effects interference dynamics behaviour, using spatially explicit individual-based model. Each follows simple behavioural rule based reserves actions neighbours (where derived from game theory models). We show dominant individuals should have larger than their subordinates, size difference increases when either food scarce, intensity suffered by increases, or distance over which affect increases. Unlike previous models, results presented in paper about differences are not prior assumptions social predation risk, emerge nothing more reduction dominants present. Furthermore, increasing intensity, availability also causes movement between ranks to increase move dominants), changes groups different found in. These discussed relation studies intra- interspecific hierarchies.
