Topic in this symposium including biogeography, biogeochemistry, global change biology, land cover and land use change, physiology, and long-term ecological research in tropical ecosystems, etc.
19 invited speakers from UK, USA, Australia, France, Argentina, and China made oral presentation on carbon cycling in tropical ecosystems. 23 delegates also shared their experience on ecological research in tropical ecosystems via poster presentation. Professor ZHOU Guoyi from SCBG made a presentation, “Excessive Nitrogen Supply Accelerate the Decline and Fluctuation of Old-growth Forest by Actuating Phosphorus Limitation”.

Participants were involved in discussion on carbon cycling in tropical ecosystems and global change biology.
The New Phytologist Symposium is a regular symposia organized by New Phytologist Trust, twice per year. The 23rd New Phytologist Symposium is the first symposia held outside of Europe and North America regions.

The purpose of this symposium is to provide a platform for international communication and cooperation on biogeochemistry and ecosystem processes acclimation to global climate change in tropical ecosystems. This symposium is also an opportunity to present ecological research in tropical and subtropical regions in China to delegates from all over the world.

This symposium was co-organized by South China Botanical Garden (SCBG) of Chinese Academy of Sciences, New Phytologist Trust, and Guangzhou Association for Science and Technology. Bureau of International Cooperation, CAS, and National Natural Science Foundation of China sponsored this symposium.
