摘要: Dispersal distance in mammals is a fundamental information for several ecological and conservation applications. Although dispersal can depend on many intrinsic extrinsic factors, recent years studies have shown that it scales with body size home range area. However, the role of further correlates to travelled still unclear predictive models proposed so far suffered from small sample lack error estimates. This reduces practical relevance We conducted comprehensive meta-analysis 327 164 mammal species, performed linear non-linear regression analyses explore relationships area distance. tested effect various life history traits factors sensitivity analysis evaluate robustness size. The both were influenced by factors. developed allometric functions estimate species based different predictors traits. Linear representing relationship between or received good support; however logistic better approximates relationships. Despite receiving less support than curve, model approximation applicative purposes. Sensitivity showed our results are robust subsampling original dataset until 40 species. Our empirical potential improve theoretical applied population biology extending applicability improving accuracy estimation large number mammals.
