Abstract Geographical range size is a fundamental ecological characteristic of species, and the product complex interactions many factors in its history. Here, we investigate causes variation among 43 species woody plant genus Betula (birches), which each occupy areas between one 20 million square kilometers northern hemisphere. We find their distributions are more affected by temperature variables than precipitation variables. The climatic niche breadth, median latitude, width seed wings, degree bark peeling, ploidy all have significant impacts on variation, but number leaf veins life form do not. Many these attributes, itself, phylogenetic component and, once phylogeny accounted for, no longer has effect size, breadth clearly most important factor. Our results therefore support niche‐breadth hypothesis for to lesser extent also dispersal‐ability Rapoport's rule that decreases toward tropics. likely be key attribute ability avoid decline or extinction under climate change.
