Research interest

Subtropical forest vegetation, with special interest in cloud forest vegetation of Taiwan. For almost decade, we have surveyed cloud forest vegetation in different parts of Taiwan, in order to get deeper insight into the community functioning of this special ecosystem. I hope to use cloud forest vegetation as a model system to describe influence of specific stress factor (fog) on community assembly, and tackle this question by various approaches, from purely descriptive (vegetation – environment associations) to more mechanical (trait-based community assembly).

Diversity patterns of vegetation at different scales and their changes in space. This includes pattern of alpha-diversity (species richness) at fine- to broad-scale level, changes in beta-diversity along environmental or spatial gradients and diversity of vegetation types at the landscape level (vegetation classification).

Methodological aspects of analysing community-ecology data. I am always curious to try new methodological approaches, but at the same time I critically ask whether the outcomes of numerical analyses really reflect their intended ecological meaning. It is clear that modern community ecology cannot go without rather advanced numerical methods handling often large and complex community datasets, but it must as well be clear that even the most advanced methods have their limitations. In a long term I focus on several methods which are more or less commonly used in vegetation ecology and which in my opinion suffer from remarkable limitations.
