Brainstorming notes
Notes from faculty brainstorming sessions regarding synthesis projects
Individual university questions:
UCB - map of CA seedsize, fire effects information service database exploration
(FEIS http://www.fs.fed.us/database/feis/plants/index.html) DAVID
UH - Community similarity vs distance at 3 scales, using species functional
groups and phylo groups to look for differences
UCI - similarity across time in Fertsyn datasets, plant versus microbial
community change in response to fertilization
Columbia - Env versus biotic filtering at multiple scales, convex hulls
FIU-can functional traits predict the magnitude of plant responses to nutrient enrichment in estuarine and wetland ecosystems? meta analysis
List of ideas for synthesis:
-Note: just because a trait changes along a gradient, is it a response trait thatis predictive of response to environmental change? patterns are integrated sum
of response and effect (UCI thoughts). use environmental manipulations to
obtain response traits, use those to predict what might happen along an
environmental gradient.
-fire response traits - (resprouting, C storage belowground, seedbank capacity)
- effect traits (production, wood density - talk to jerome)
- water flow data (USGS streamguage, Jason's expertise)? GIS layers of fire history? JASON - has FRAP fire history from 1922 - 2007 for CA.
-effects traits important for ecosystem services. Different than the BEF argument, can the provision of certain ecosystem services be traced back to plant traits and the abundance weighted mean trait value? A few studies starting to show a link, or at least trying too. For example, see a general discussion by Diaz et al. (2007) and Mark and Dickinson (2008) for an example of a paired catchment study with two differing primary veg types.
-species distribution changes with shifts in precipitation - ask Scott for more watering
experiments?
- space for time subsitution in traits, maybe use abundance weighted traits means for
different years with different precipitation
- paleo literature - leaf size vs precipitation, % of flora with teeth vs temperature, SLA
versus nutrient availability
- traits predicting liklihood of fire, species responses to fire, effects of shifting
composition after fire, and ecosystem services
- controlled burn experiments? grasslands might be good here, as well as woody
some data sources:
-Large scale range shifts
-Forest Inventory plots http://fia.fs.fed.us/tools-data/default.asp (UCI with fire history
maps)
- california fire perimeters map and GIS data: http://frap.cdf.ca.gov/data/frapgismaps/download.asp
- Berkeley's fire research center: http://firecenter.berkeley.edu/
- outbreaks (Elsa will talk to juliann aukema), large environmental gradients, would need
to collect the traits, probably only georeferenced at the level of the county
-the California Weislander vegetation plots: http://vtm.berkeley.edu
- VEGBANK (http://vegbank.org/vegbank/index.jsp idiosyncratic repository)
- USDA PLANTS - Dan et al. have downloaded and written R scripts
- TAXON scrubber (Brian Enquist's tool)
- PRISM climate data: http://prism.oregonstate.edu/
- FIA database: http://fiatools.fs.fed.us/fiadb-downloads/fiadb3.html
- note that Columbia is pulling seedsize out of Kew seedsize database - We are working on a simple script to harvest seed size data for a given species list. I agree with David that we might want to put together a master list and request data directly from John Dickie, the SID contact.
How to structure/group the questions:
-get students talking/interacting over the web before they come
-develop 2-3 questions before the meeting
-within university projects are independent, the folks at the synthesis won't bring
projects/tasks back
-California/Southeast/New England groups
- woody/herbaceous/wetland?
- fire/nutrients/precip/temp
Questions for Scott: are there good precip gradients across the interior of the US where we
could layer experimental responses along the gradient? (Mendy Smith/Alan Knapp synthesis -
does interannual variation in precipitation parralel the kinds of patterns you see along
spatial gradients in precipitation)
Here is information about fire maps in California:
The Fire Perimeters data consists of CDF fires 300 acres and greater in size and USFS fires 10 acres and greater throughout California from 1950 to 2002. Some fires before 1950, and some CDF fires smaller than 300 acres are also included. To ensure high quality fire perimeters data are avialable to the public and to cooperating agencies. This layer should not be used for statistical analysis. When compared to the Wildfire Activity Statistics Report it is only 90% complete. The Wildfire Activity Statistics Report is created annually by the California Department of Forestry and Fire Protection. You can download the entire GIS dataset http://gis.ca.gov/catalog/BrowseRecord.epl?id=21086
From the FIA library it looks like we are interested in phase 2 and potentially phase 3 data:
