Chinese scientists study alpine ecosystem carbon cycling under climate change
Chinese researchers have released new findings on how alpine ecosystems respond to long-term climate change, focusing on carbon cycling and plant productivity. The study was conducted by the Northwest Institute of Plateau Biology of the Chinese Academy of Sciences, in collaboration with several universities and institutions across China.
The research examined plant phenology, or seasonal biological events such as flowering and leaf growth, in alpine grasslands over a 15-year period. Scientists found that warming significantly increased above-ground net primary productivity (ANPP), a key measure of ecosystem functioning and carbon sequestration. Cooling, on the other hand, reduced ANPP, though its effects did not intensify over time.
The study highlighted that early-season plant phenology plays a critical role in regulating ecosystem responses to temperature changes. Warming effects on productivity became stronger over time, while cooling effects remained relatively stable.
Researchers emphasized that these findings improve understanding of how temperature variations influence plant traits and ecosystem functions. Future studies will explore how changes in plant diversity and functional traits affect ecosystem stability under different climate scenarios.
The Northwest Institute of Plateau Biology (NWIPB) is part of the Chinese Academy of Sciences and is located in Qinghai Province. Established in 1962, NWIPB focuses on ecological and biological research in high-altitude environments, including the Tibetan Plateau. Its work covers biodiversity, ecosystem dynamics, and climate change impacts. The institute collaborates with domestic and international partners to advance ecological science and provide guidance for sustainable development in fragile alpine regions.
--- Would you like me to also adapt this into a short infographic-style summary with key numbers (like 15 years of data, ANPP increase, etc.) so it's easier to visualize?
