“…Numerous phylogeny-based ecological studies have been published in the recent decades since Cam Webb's work on community phylogenetics [20], in which the degree of relatedness among species in ecological communities was calculated using branch lengths in a phylogenetic tree. Historically, these studies have focused on DNA barcode trees, which are constructed using either single-or multiple-gene sequence data, and several studies have indicated that barcode trees may have promising performance for inferring community phylogenetic structures [21][22][23]. Nonetheless, there is a growing awareness that barcode trees are still problematic, compared with more robust phylogeny trees (e.g., placement trees, which place the barcodes on published phylogenies), whether they are robust or not, when considering the assembly mechanisms of communities [24], especially in species-rich geographical regions [25].…”

Mountain ecosystems harbor evolutionarily unique and exceptionally rich biodiversity, particularly in insects. In this study, we characterized the diversity, community stability, and assembly mechanisms of butterflies on a subtropical mountain in the Chebaling National Nature Reserve, Guangdong Province, China, using grid-based monitoring across the entire region for two years. The results showed that species richness, abundance, and Faith’s phylogenetic diversity decreased with increasing elevation; taxonomic diversity played a considerable role in mediating the effects of environmental changes on stability. Moreover, our results showed that stochastic processes are dominant in governing the assembly of butterfly communities across all elevational gradients, with habitats at an elevation of 416–580 m subjected to the strongest stochastic processes, whereas heterogeneous selection processes displayed stronger effects on the assembly of butterfly communities at 744–908 m, 580–744 m, and 908–1072 m, with abiotic factors inferred as the main driving forces. In addition, significant differences were detected between the barcode tree and the placement tree for the calculated β-NTI values at 416–580 m. Overall, this study provides new insights into the effects of environmental change on the stability and assembly of butterflies in Chebaling, which will be beneficial for biodiversity conservation and policy development.
