1.Title of Presentation:  Global variation in ecosystem carbon use efficiency derived from eddy covariance observations 

Presenter: Asst Prof. Luo Xiangzhong

Awarded the Best presentation of the conference

Abstract : Terrestrial ecosystems have been serving as a strong carbon sink that offsets one quarter of anthropogenic CO₂ emissions in the past decade. Carbon use efficiency (CUE), the percentage of photosynthesized carbon plants store in biomass, is a major factor determining the efficiency of this ecosystem service. Here we used advanced statistical methods, flux data and ecological theory to infer a new global database of carbon use efficiency.

2.Title of Presentation: Slower changes in vegetation phenology than precipitation seasonality in the dry tropics

Presenter: Dr. Tian Jiaqi

Abstract: The dry tropics occupy forty percent of the tropical land surface and play a dominant role in the trends and interannual variability of the global carbon cycle. While several studies have reported that the dry tropics are experiencing significant changes in the wet/dry-season length (i.e., precipitation seasonality), the accompanied changes in vegetation have not been examined. In this study, we thus explored the vegetation changes in the dry tropics over the past 40 years and uncovered underlying mechanisms.

3.Title of Poster: Interannual Variability of Carbon Dioxide (CO₂) and Methane (CH₄) Fluxes in a Rewetted Temperate Bog over a 5-Year Period

Presenter: Tin Widyani Satriawan

Abstract:Rewetting in previously drained peatlands is important for re-establishing their role as carbon sinks. Here, we evaluated the interannual variability of greenhouse gas (GHG) fluxes at a rewetted temperate bog based on eddy covariance measurements. We found that the rewetted bog alternated between being an annual CO2 sink and source, while consistently being a CH4 source. Despite mainly acting as a GHG source, the rewetted bog will likely have a cooling effect on climate over long timescales compared to drained bogs.

Title of Presentation:

Tropical extreme droughts drive long-term increase in atmospheric CO2 growth rate variability

Presenter: Asst  Prof. Luo Xiangzhong

Abstract: The tropics play a dominant role in the variability of the global carbon cycle, however, how the magnitude of variability changed in recent history remains unclear. Here we used atmospheric observations in combination with climate data to delineate a key role of tropical extreme droughts in explaining the changes in global carbon cycle variability
