| Özet |
| Predictable empirical patterns of variation in body size along spatial and environmental gradients have been documented within many species of mammals. Four main hypotheses, heat conservation, heat dissipation, primary productivity and seasonality, have been proposed to explain these patterns of variation in body size. In this study, we reported an analysis of geographic variation in body size of Richardson's ground squirrels Urocitellus richardsonii, a North American hibernating, burrowing mammal. Firstly, we evaluated whether a Bergmannian size pattern was exhibited by Richardson's ground squirrels. Secondly, we used an information‐theoretic approach to test which of the four main hypotheses best explain(s) geographic variation in body size of Richardson's ground squirrels or to assess whether, as proposed by McNab's ‘resource rule’ or Huston and Wolverton's ‘eNPP rule’, the primary productivity … |
