2.6 Species dispersal distance
We estimated the dispersal capacity of North China leopard according to the allometric growth equations (Santini et al., 2013 ), with body weight and home range as inputs data. Information about North China leopard’ body weight was extracted from the literature (Online Resources). The adult male body weight of North China leopard is about 60-75 kg, and the adult female is about 40-55 kg. Data on home range were from panTHERIA (Jones et al., 2009 ). The maximum dispersal distance of North China leopard is calculated asd =13.11×BS 0.34×HR 0.27,BS is body weight (kg), HR is home range (km2), and dispersal distance d is in km.
