The doctoral thesis entitled “Disentangling Mechanisms Underlying Tree Species Coexistence: Integrating Phylogenetic and Functional Dimensions” by Dr. YANG Jie of Xishuangbanna Tropical Botanical Garden (XTBG) has been enlisted in the 2016 Provincial Excellent Dissertations of Yunnan. The rating of her dissertation is superior.
   During her studies for a Ph.D degree, Dr. Yang Jie and her teachers applied individual species area relationship (ISAR) and individual phylogenetic area relationship (IPAR) approaches to study the relative importance of niche or neutral processes as drivers of species coexistence across scales within nine forest dynamics plots (FDPs). The study mainly resulted in the importance of post evolutionary history in dictating the ecological interactions; abiotic determination is more important at larger scales while biotic determination is more important on smaller scales within community. Moreover, there is strong filtering of lineages and combinations of  functional trait states by environment.
   The award honored 32 doctors who recently received their academic degrees in universities and research institutions based in Yunnan. Among them, 8 dissertations were rated as superior by the Education Department of Yunnan Province and Yunnan Academic Degrees Committee.
