Small mammal diversity and community structure exhibit congruent hump-shaped patterns along a subtropical elevational gradient
Published 2024-12-01“…Human footprint, Normalized Difference Vegetation Index, precipitation seasonality and potential evapotranspiration are key drivers of small mammal diversity and community structure along elevational gradients. In summary, our study provides evidence that phylogenetic diversity is a robust surrogate for functional diversity, and challenges the recent large-scale studies that advocate a linear relationship between small mammal assembly process and elevation. …”
