The southeastern edge of the Qinghai-Tibet Plateau (Yunnan, China) exhibits high biodiversity but stark differences in species richness between its western Longitudinal Range Gorge (LRG) and eastern Yunnan (YP). We collected distribution data for 16 primate analyzed palynological records over past 20 ka from 21 localities to identify biogeographic, climatic, anthropogenic factors that have driven present-day primates this region. By integrating local ecological knowledge, field surveys, models, niche utilization rates, historical vegetation land use changes, we found spatial-temporal shifts monsoon climate been a critical factor shaping on Plateau. Compared YP, LRG receives more precipitation, has limited seasonal temperature variation, higher minimum temperatures during coldest month. These conditions facilitated development moist evergreen broadleaf forests, which represent suitable habitat 14 inhabit area. In contrast, drought-adapted forests YP support only one species. Palynological indicate differentiation predates human influence. However, 2000 years, loss hunting significantly affected primates. ranges gibbons, langurs, snub-nosed monkeys are now restricted central northern regions disappeared lower elevations. Lorises their northernmost range. macaques remained relatively stable. Yangtze-Red River-24° N line marks biogeographic boundary Yunnan. Our research suggests changes fundamentally shaped contemporary richness, while recent pressures caused 'range contraction' many taxa.
