Masatoshi Katabuchi (片渕正紀)
I am an Associate Professor at Xishuangbanna Tropical Botanical Garden (XTBG), Chinese Academy of Sciences (CAS). My research focuses on using functional traits and statistical and simulation models to better understand forest (or any kind of) diversity, including how they respond to climate change.

Community assembly and dynamics of tropical trees
How tropical forest tree communities are assembled from species pool? Numerous hypotheses have been proposed to explain patterns of diversity in tropical tree communities. For example, we showed that soil fertility works as a strong habitat filter for a tropical forest tree community. A long-term goal of this work is to create a more quantitative approach for understanding community assembly rules and for predicting future biodiversity.
The composition of natural communities is changing as species respond to multiple anthropogenic drivers. We are contrasting multiple-level (i.e., species, community…) analyses of change in the functional composition in tropical forests to gain mechanistic understanding of forest responses.
Leaf functional diversity
Across the global flora, photosynthetic and metabolic rates depend more strongly on leaf area than leaf mass. In contrast, intraspecific variation in these rates is strongly mass-dependent. This inconstancy poses a fundamental question for ecophysiologists, as well as challenge for accurately representing leaf function in dynamic global vegetation models (DVGMs).
We are developing new quantitative framework to understand causes and consequences of leaf trait variation.
