Dispersal traits linked to range size through range location, not dispersal ability, in Western Australian angiosperms

摘要: Aim  We examine the relative importance of seed dispersal mode in determining range size and placement 524 species from six focal plant families (Agavaceae, Euphorbiaceae, Malvacaeae, Sapindaceae, Proteaceae Fabaceae (Acacia)). Location  Western Australia. Methods  Taxa were categorized by life-form their distributions modelled using maxent. Geographical was compared amongst mode, biome phylogenetically independent contrasts. considered a similar manner. Results  Range did not vary with (ant versus wind vertebrate dispersal) or life-form, instead varied primarily as function biogeographical region which found. placement, however, among modes, consequence that diversity wind- ant-dispersed plants increased latitude while vertebrate-dispersed more evenly distributed. Main conclusions  For taxa studied, sizes Although differences may exist differing they are likely to be far smaller than different regions. The trait most affect geographical size, hence rarity risks associated other threats, simply has evolved.
