Midpoint attractor models resolve the mid‐elevation peak in Himalayan plant species richness

The midpoint attractor (MPA) models of species richness integrate a unimodal environmental favourability gradient and neutral effects forced by geometric constraints thus extend the ecologically mid-domain model. However, both alternative MPA algorithms assume that underlying peaks within modelling domain. Here, we used elevational distribution data for 1054 plant occurring in northwest Himalaya to explore gradients performance groups defined biogeography, taxonomy life-form. achieved an excellent fit, but two produced contrasting estimates location, especially with originating lowlands. Therefore, propose modification model accounting peak outside study domain reflect these situations. Biogeographic origin was more decisive location than taxonomic or life-form classification, indicating relatively low climatic niche conservatism plants.
