Functional diversity of Himalayan bat communities declines at high elevation without the loss of phylogenetic diversity

Abstract Species richness exhibits well-known patterns across elevational gradients in various taxa, but represents only one aspect of quantifying biodiversity patterns. Functional and phylogenetic diversity have received much less attention, particularly for vertebrate taxa. There is still a limite...
