Planning for Thursday’s Morning and Afternoon breakout groups

Questions for report back at end of morning and afternoon sessions: (5-7 minutes each)

• Name ~1-3 overarching questions, and for each, describe your general approach (data used, statistical or modeling methods, hypotheses tested, future cross-site experiments…)

• Describe your proposal for the ASM – leader, title, rough sketch• Anticipated product(s) • Point person, group names, people to invite

Suggested sessions for Inorganic Nutrients1. Morning: Climate change effects on retention (vs. export) of inorganic nutrients (Giblin)

2. Morning: Climate change effects on inorganic nutrient transformations (Hollibaugh)

3. Morning: Role of nutrients and stoichiometry in controlling primary production and species composition and vice versa? (Seabloom)

4. Morning: Investigation of long-term data using new approaches and models (e.g. Variance structures of nutrient concentrations across space and time) (everyone should do this!!!) volunteer?

5. Morning: Impacts of changing precipitation chemistry over the long-term record (Hamilton)

6. Morning: Cascading impacts of nutrient availability on food webs and vice versa (including the influence of stoichiometry)? (Ruess)

7. Morning: Implications for autotrophs and heterotrophs of long-term changes in microbial nutrient use efficiency (Mack)

8. Afternoon: Coupled biogeochemical processes and stoichiometry - N, P, and organic C dynamics in ecosystems (Kominoski)

9. Afternoon: Greenhouse gas emissions / Ecosystem role in climate-change feedbacks (Silver)

10. Afternoon: Long-term role of human-decision making and its impacts on inorganic nutrients (e.g. Clean water act, populations on sewerage, etc) (Driscoll)

11. Afternoon: Role of disturbance in altering inorganic nutrient dynamics (fire, flood, etc.) (Melack)

12. Afternoon: How do nutrient budgets (and the importance of recycling) vary across the range of LTER sites? (Holbrook)

13. Afternoon: How do nutrient exports/dynamics vary as a function of connectivity (within and across patch types)? (Gooseff)
