摘要: Roe deer (Capreolus capreolus) has a wide distributional range in Europe and inhabits broad of habitats environmental conditions. Thus, populations roe show substantial variation demographic parameters. We aimed to determine whether body mass population density—which influence the reproductive potential at local scale—affect their biogeographical scale as well. reviewed literature (covering years 1948–2015) on utero litter size from 59 locations 14 countries Europe. Across study sites, mean varied 1.0 2.4 embryo or corpora lutea per female, density ranged 4.5 73.5 individuals/km2. Mean 11.2 20.8 kg subadult females 12.1 22.4 kg adult females. Between 46° 56° N, did not significant trend increase, whereas between 63° it increased with latitude (Bergmann’s rule). used linear mixed-effects models (LMMs) analyse (analysed separately) size. Females larger produced litters, this pattern was pronounced both higher lower latitudes. Higher densities negatively affected sample all This macroecological analysis showed that factors influencing scales produce similar effects scale.
