My laboratory has been doing a number of multidisciplinary projects examining the relationships among soil properties and microbial activities and communities in a variety of forest ecosystems, including mangrove, coastal sand dune, montane, and subalpine forests. We have examined natural forests as well as secondary forests resulting from natural and anthropogenic disturbances. My team represents one of the few integrated groups in Taiwan working on pedology, biogeochemistry, microbial ecology, and metagenomics in forest soils. To elucidate the mechanisms involved in ecological processes, we have paid lots of efforts on long-term ecological research. Particularly, persistent work has been done at the Yuanyang Lake (YYL) Nature Preserve. Our studies put emphasis upon the structure and function of the forest ecosystem as well as the hydrological and nutrient flux of the ecosystems. Many concepts and methodologies developed from the YYL site have been applied in different forest ecosystems.
