Species interactions form the core of ecosystem functions and represent a key process shaping biodiversity patterns. Research on the interactions between frugivorous birds and fruiting trees in natural ecosystems is an important approach to understanding the mechanisms of cross-trophic species interactions and their ecological impacts. Compared with natural ecosystems, urban areas exhibit disti...
Remote Sensing Multimodal Large Model Wins "New Model" Innovation Achievement Award at China International Digital Economy ExpoRecently, the series of remote sensing multimodal large model developed by the research group led by Professor Huang Xiaomeng from the Department of Earth System Science (DESS) at Tsinghua University was awarded the "New Model" Innovation Achievement Award at the 2025 C...
Long-term, continuous, and spatially explicit monitoring of global livestock dynamics is fundamental to understanding issues related to food security, public health, ecological and environmental change, and sustainable development. Over the past decades, institutions such as the Food and Agriculture Organization of the United Nations (FAO) have accumulated extensive agricultural statistics. How...
Sea ice is a critical component of the climate system. The Marginal Ice Zone (MIZ), a key region for sea ice formation and decay, plays an indispensable role in the recent dramatic changes in Antarctic sea ice. Due to the harsh natural environment in the marginal ice zone, in-situ observations and datasets are extremely limited. Meanwhile, traditional remote sensing methods are not suitable for...
Soil moisture-precipitation coupling is a key aspect of land-atmosphere interactions. However, there are substantial disagreements among different climate models in simulating the strength of this coupling, and the underlying physical pathways—specifically, whether soil moisture affects precipitation through surface sensible heat (SH) or evapotranspiration (ET)—remain unclear. To address thes...
In September 2025, the Fifth World Congress of Biosphere Reserves (the 5th WCBR) was held in Hangzhou, China, where landmark outcomes such as the Hangzhou Strategic Action Plan and the Hangzhou Declaration were released. The World Network of Biosphere Reserves (WNBR) is the core vehicle of UNESCO's "Man and the Biosphere Programme" (MAB). As two significant international agendas, the synergy be...
On September 18, a collaborative study by Professor Zhang Qiang’s team from the Department of Earth System Science (DESS), Tsinghua University, and Associate Professor Zheng Bo’s team from the Institute of Environment and Ecology, Tsinghua Shenzhen International Graduate School, titled “Global warming amplifies wildfire health burden and reshapes inequality”, was published online as an “Ac...
Against the backdrops of climate change, large-scale extreme wildfires are becoming more frequent, with profound consequences for the global carbon cycle, ecosystems, air quality, and public health. Accurately and swiftly assessing the air pollution and health risks associated with these events is crucial for improving wildfire monitoring and early warning systems, and for safeguarding populati...
