Presentation transcript:

Planning for Thursday’s Morning and Afternoon breakout groups Questions for report back at end of morning and afternoon sessions: (5-7 minutes each) What hypotheses did you come up with and what data would you use? Describe next steps, including proposals for ASM meeting – leader, title, and/or other working group options (SESYNC, Powell Center)? Is this a good topic for NSF Mini symposium next winter? Title of talk? Could this develop into a Synthesis paper? Who is contact for people who want to join in?

Suggested sessions for Inorganic Nitrogen Climate change effects on uptake, retention, transport and transformation of inorganic nutrients across ecosystems (n=12) Coupled biogeochemical processes and stoichiometry - N, P, and organic C dynamics in ecosystems (n=14) Role of nutrients and stoichiometry in controlling primary production and speciewws composition/diversity or the reverse how does primary production and species diversity influence biogeochemistry? (n=10) Greenhouse gas emissions / Ecosystem role in climate-change feedbacks (n=7) Investigation of long term data using new approaches and models (e.g. Variance structures of nutrient concentrations across space and time) (n=3) Changing precipitation chemistry over the long-term record at LTER sites (n=8) Long-term role of human-decision making and whether we are seeing the impacts (e.g. Clean water act, populations on sewerage, etc) (n=6) Role of disturbance altering biogeochemical cycling of inorganic materials (storms, droughts, and removing riparian veg, forest harvest) (n=11) How does nutrient availability cascades through food webs and the influence of stoichiometry (compare belowground, aboveground and aquatic food webs)? (n=3) How do nutrient budgets (and the importance of recycling) vary across the range of LTER sites? Links to Carbon budgets including P as well. (n=6) Heterotrophic and autotrophic responses to encompass microbial use efficiency (n=4)
