主 题:Community structure Elevational gradient Environmental filtering Functional and phylogenetic diversity Mountain systems
摘 要:Mountain systems harbor an evolutionarily unique and exceptionally rich biodiversity,especially for ***,the associated elevational gradients and underlying mechanisms of amphibian diversity in most mountain systems remain poorly ***,we explored amphibian phylogenetic and functional diversity along a 2600 m elevational gradient on Mount Emei on the eastern margin of the Qinghai-Tibetan Plateau in southwestern *** also assessed the relative importance of spatial(area)and environmental factors(temperature,precipitation,solar radiation,normalized difference vegetation index,and potential evapotranspiration)in shaping amphibian distribution and community *** showed that the phylogenetic and functional diversities were unimodal with elevation,while the standardized effect size of phylogenetic and functional diversity increased linearly with *** net relatedness,nearest taxon index,and functional net relatedness index all showed a positive to negative trend with elevation,indicating a shift from clustering to overdispersion and suggesting a potential change in key processes from environmental filtering to competitive ***,our results illustrate the importance of deterministic processes in structuring amphibian communities in subtropical mountains,with the dominant role potentially switching with *** study provides insights into the underlying assembly mechanisms of mountain amphibians,integrating multidimensional diversity.
