Evolution of heterospecific attraction: using other species as cues in habitat selection

摘要: We analyzed the ecological conditions that may favor a habitat selection process in which later arriving individuals (colonists) use presence of earlier established species (residents) as cue to profitable breeding sites (heterospecific attraction). In our model, colonists assessing potential patches could select between high-quality source and low-quality sink patches. A proportion were occupied by residents. Colonists either directly sample relative quality (termed samplers) or, alternatively, they also residents patch (cue-users). Cue-users gained benefit from lowered costs when The cue-using strategy is an efficient way choose best possible not only interspecific competition intense, but benefits social aggregation exceed effects competition. High cost sampling empty increases fitness samplers. strongest attraction heterospecifics was predicted aggregating with exceeded competition, approximately half landscape consisted occupied,
