Underestimated effects of climate on plant species turnover in the Southwest Australian Floristic Region

Spatial turnover in plant species composition reflects the interplay between species’ environmental requirements and their dispersal dynamics. However, its origins are also historical, arising from speciation, extinction and past range dynamics. Here, we test the effects of current environmental gradients and geographical distance on regional species turnover. Using a new approach, we then interpret residual turnover patterns, unexplained by these factors.
