摘 要：Aims Biodiversity patterns along elevational gradients have been well ***,the variations of biodiversity patterns along elevations and their underlying mechanisms are still *** multiple facets of biodiversity provides novel insights into the mechanisms for driving community *** this study,species abundance information was incorporated into taxonomic and phylogenetic diversity to reveal the ecological and evolutionary forces of plant community assembly along an elevational gradient in subtropical *** We selected 17 woody plant plots along an elevational gradient from 270 to 1470 m in eastern China’s subtropical *** presence-based and abundance-based measures of angiosperm species were used to quantify taxonomic alpha diversity,phylogenetic alpha diversity,phylogenetic relatedness,as well as taxonomic and phylogenetic dissimilarity among these *** the relations between these measures and climatic and topographic variables were *** Findings For both abundance-weighted and unweighted measures,we observed an overall increasing pattern for taxonomic alpha diversity along elevation,and distance-decay trends of taxonomic and phylogenetic similarity with increased elevational ***,there were disparity patterns of phylogenetic alpha diversity between abundance-weighted and unweighted *** phylogenetic structure,there was no significant trend along *** topographical and microclimatic variables were main drivers of diversity patterns and phylogenetic *** with unweighted measures,abundance-weighted measures were strongly related with the slope and stand basal ***,our results prove that deterministic processes mediated by local species abundance imprint on plant community composition along the elevational gradient.
