The Scaling of Animal Space Use

摘要: Space used by animals increases with increasing body size. Energy requirements alone can explain how population density decreases, but not the steep rate at which home range area increases. We present a general mechanistic model that predicts frequency of interaction, spatial overlap, and loss resources to neighbors. Extensive empirical evidence supports model, demonstrating constraints on defense cause exclusivity use decrease In large mammals, over 90% available may be lost Our offers framework understand animal space sociality.
