Dear colleagues,

Please find below and attached the draft agenda for the upcoming Hubbard Brook Quarterly Project Meeting, to be held over Zoom 10-2:30 EDT on Wed. April 7.  Zoom link to follow at a later date.

The overall topic is the LTER Renewal proposal. Topics proposed are all discussions, and will be led by Peter Groffman & Pam Templer.

The LTER Renewal Proposal

Agenda

• 10:00 Introductions

• Process and timeline (Groffman and Templer)

–    Writing team

–    How we did this last time

–    Budgeting

– Timeline

– What was in the last LTER proposal?

– Synthesis updates

– IM update from Mary Martin 

• 10:45: Do we need a new conceptual model? [see below] (Groffman)

• 11:30: What are the key data streams we need to keep? (Templer)

– Climate

– Hydrology

– Steam chemistry

– Vegetation

– Soils

– Hydropedology

– Birds

– Insects

– Modeling

– Experiments:

o CCASE

o MELNHE

o Elevation gradient

• 12:00: Lunch

• 12:30 What are the big surprises that have emerged over the past six years? (Groffman)

– Evapotranspiration,

– Trees marching down the hill

– Conifers doing very well

– Phosphorus co-limitation

– Insect declines

– Nitrogen oligotrophication

– Deacidification and carbon loss

– Declining resilience

– Public engagement surprise

• 1:15: Business Meeting (Goodale and Battles)

• 1:45 What new initiatives should we consider? (Templer)

– Something spatial: Hotspots of change in the landscape – streams, hydropedo. Make some predictions about just where in the landscape are poised for change. FUFOR.

– Foliar N and the rules of life to integrate biodiversity and biogeochemistry.

– Resilience in the long-term data streams

– Diversity, equity and inclusion – humans, evolution of our community.

– Molecular linking community composition with function

– It’s the trees stupid!

o Evapotranspiration

o Novel communities, e.g., red spruce and white pine

• Additional Topics

– What are lessons from the mid-term review?

– What are key gaps linked to surprising results (remote sensing, meteorology, other)?
