Choy's Ecology and Remote Sensing Lab
Department of Geography, National Taiwan University
 |
Researchers in Choy's Ecology and Remote Sensing Lab use synoptic sensing methods to integrate information acquired from the field and the sky/space to investigate the impacts of amplified climate change on terrestrial ecosystems at the regional and global scales. Our research mainly focuses on the tropical region including seasonally dry forest, rainforest and montane cloud forest. Here are the specific topics:
- Impacts of elevated temperatures and amplified droughts on tropical forest ecosystems;
- Spatially explicit metabolic scaling approach to estimate tropical forest productivity;
- The role of fog playing in carbon cycling of tropical montane cloud forests.
Students, postdocs and visiting scholars who are interested in the topics please contact me. Email is at the bottom of this web page.
