|Abstract||Tropical rainforests represent the most species-rich and at the same time the most fragmented terrestrial biome on Earth. Fragmentation of tropical rainforests is having wide-ranging consequences for the maintenance of local species diversity and community assembly patterns. In this paper we focus on Manyangguang holy hill in Xishuangbanna, SW China with the aim of examining both floristic and community phylogenetic structure changes after decades of fragmentation. A new taxonomic diversity algorithm (within-family diversity) was developed to assess floristic changes in the fragmented forest. Community phylogenetic structure was then compared before and after fragmentation. We found that high species turnover occurred in the fragmented forest and taxonomic diversity changed greatly among families, with changes occurring randomly throughout the phylogenetic tree. While shade-tolerant species have been lost, and ruderal and alien species have been added, the overall phylogenedc diversity has increased with species being more phylogenetically distant. The community phylogenetic structure changed distinctly from clustering to dispersion, which was related to the relatively drier conditions in the forest after fragmentation, resulting in an increase of phylogenetically remote heliophytes and the loss of closer-related sciophytes from the forest.|
