B23K:
Understanding Phenology across Scales and Improving Linkages to Ecosystem Functions II


Session ID#: 8911

Session Description:
The seasonal timing of vegetation development and activity is shifting as earth’s environment changes.  These phenological shifts are best understood for past changes and within, rather than across, spatial scales.  New research expands our understanding across scales from species to communities to watersheds and towards the future through forecasting models.  Recent developments improve our ability to link shifts in the timing of vegetation development and activity to the impacts on ecosystem functions, such as food production, carbon exchange, and water cycling.  Submissions are solicited for phenology studies that showcase new methods, insights, applications, and outreach that add to our understanding of phenology across scales and towards predictions of how shifts in phenology will alter critical ecosystem functions on which people depend.
