B34C:
Vegetation Phenology as Forcing and Response Across Diverse Biomes: Detection, Attribution, Prediction, and Implications III

Submit an Abstract to this Session



Session ID#: 32032

Session Description:
Vegetation phenology is an integrated and sensitive indicator of ecosystem health and function that responds to growing conditions, disturbance, and climate change. Changes in phenology can also exert feedbacks on ecosystems and to the climate system by regulating vegetation dynamics and key land surface processes. This symposium draws upon recent advances in the detection of spatio-temporal variations in vegetation phenology with traditional and/or novel monitoring approaches (e.g., satellite, webcams, fluorescence, citizen scientist observations, crowdsourcing), and the attribution of these variations to underlying mechanistic processes. In addition, the session is looking forward to studies targeting accurate model representations of vegetation phenology at all scales, and/or investigating the phenological implications to key land surface processes and the societal sector. Abstracts reflecting the increasing research efforts across diverse biomes, including tropical forests, tundra and terrestrial-aquatic systems in addition to the temperate biome, are encouraged.
