Microclimate heterogeneity in Southeast Asia and its implications for biodiversity remain understudied. We investigated microclimate changes between 1982 and 2017 using high-resolution data and a patch-mosaic model. Our findings reveal a decline in microclimate heterogeneity (as indicated by Shannon's diversity index) and a significant increase in elevation. Topographical factors (∼50.6%) and climatic factors (∼21.5%) primarily influenced the decline. Spatial heterogeneity weakened with larger moving windows and coarser grid-scale data sets. Our study suggests that shifting mountainous microclimates play a crucial role in mediating biodiversity in Southeast Asia.
