1. NASA Biodiversity Research & Ecological Forecasting: Answering the New Dismal Science Woody Turner University of Maryland Inn and Conference Center August 21, 2006 Joint Workshop on NASA Biodiversity, Terrestrial Ecology, and Related Applied Sciences

2. Workshop Goals Where is biodiversity science going over the next decade or so & what is NASA’s role? How can we transition research activities to operations and decision support through the Ecological Forecasting and other programs?

Millennium Ecosystem Assessment Vol. 1 Extinction rate 100x background rate 12% to 52% of species in well-studied taxa threatened with extinction under Red List We are the cause Climate change potentially dominant driver Conservation Biology 20 th Anniversary “… nature is still losing badly.”

5. Definition of Biodiversity from GBA (1995) is “the total diversity and variability of living things and of the systems of which they are a part”- includes genetic, organismal, and ecological components Main Message: Biodiversity science needs NASA observations and models to understand patterns and processes at landscape to global scales.

Indeed, it is increasingly apparent that knowledge of the roles of pattern and process at different scales is at the very heart of an understanding of global variation in biodiversity. Kevin J.

WHY? Because molecular techniques will (1) lead us directly to the processes driving ecosystem functioning; (2) allow us to capture ecosystem & biodiversity change (i.e., evolution) in action; & (3), through phylogeny, they are our best window into history and historical effects!

13. Little Rock Lake in Wisconsin; produced by Neo D. Martinez of San Francisco State University,Neo D. Martinez Romberg Tiburon Center for Environmental Studies Models Unite Observations of Pattern and Link Them to Processes Models of trophic webs are a key tool in that they not only link the ecological players but also connect physical and biological realms: Follow the Energy!

14. Ecological Forecasting = using observations and models to predict the impacts of environmental change, whether natural or anthropogenic, on the ecosystems that sustain us. One example (or all we need to do) is: GCM  Regional CM (~1 km grid)  Biogeochemical Cycling Model  Ecophysiological Model  Trophic Model  PHVA Model Result: Impact of climate variability and change on species of concern (be they T&E species, invasives, pathogens, whatever)! Is this foolish? Naïve? Overly simplistic? Perhaps. Linking models, much less coupling them, is not trivial! Except many of you are already doing pieces of this!

15. One Way Forward Mind the gaps! Build bridges! –Target your work at the gaps between those different modeling approaches to make the most progress (e.g., Behrenfeld’s focus on the C growth rate term as a bridge between biogeochemical & physiological approaches) –Example of another marine challenge: we are linking regional climate to biogeochemical carbon models (a la JPL/Chao- UME/Chai) for primary producers (phytoplankton); however linking this to the models of changes in zooplankton, and thereby getting to the next step on the trophic web, is a major hurdle—ultimate goal to go from climate to large fish What can we do here? –No one should leave this workshop without making an interdisciplinary connection! Seriously!

16. Some Key Science Questions How does biodiversity relate to the functioning of ecosystems? What are the effects of spatial scale on patterns of biodiversity? How do climate variability and change affect the abundance and distribution of organisms? How do ecosystems change in response to anthropogenic disturbances and how does biodiversity mediate these changes? How does the level of energy in an ecosystem affect its biodiversity? What is the role of ecosystem physical structure in promoting and maintaining biodiversity? Are the organisms in communities fungible, e.g.: how stable are trophic webs at retaining their function? What are the hottest of the hot spots for retaining maximum species diversity, i.e.: is there taxonomic covariance in species richness and abundance and, if so, where is it? What are the best RS proxies for ecosystem diversity and ecosystem health (e.g., NDVI, NPP, soil moisture, SST/SSH & location of fronts, vegetation structural complexity, rates of disturbance, rates of upwelling, etc.)? And what scales of sensing are necessary? Can we catch evolution in action by first correlating environmental changes at landscape/broader scales with genomic/proteomic changes? What is the role of history in establishing local and regional biodiversity?
