Modeling and Visualizing Species Movement Presented at: NASA Joint Science Workshop on Biodiversity, Terrestrial Ecology, and Applied Science College Park, Maryland, August 21-25, 2006 Funding: NASA NCC2-1186 & NCC13-03009, NSF DEB 0074444 & DEB-0413570, and NPS Fred Watson 1 Simon Cornish 1 Simon Cornish 1 Bob Garrott 2 Bob Garrott 2 PJ White 3 PJ White 3 Rick Wallen 3 Rick Wallen 3 Susan Alexander 1 Susan Alexander 1 Wendi Newman 1 Wendi Newman 1 Thor Anderson 1 Thor Anderson 1 Jon Detka 1 Jon Detka 1 Jason Bruggeman 2 Jason Bruggeman 2 1 California State University Monterey Bay 2 Montana State University Bozeman 3 National Park Service
2
National Parks Service bison monitoring & management activities
3
A selection of products in the pipeline Landscape visualization kiosk –Canyon Visitor Education Center Real-time snowpack modeling –Information that supports bison management at the boundary Landscape inputs to wildlife studies –The hard science upon which policy is based A model for predicting species movement –Potential contributions to any application where species move: biodiversity invasive species ecological forecasting disease vectors
4
Landscape visualization kiosk
6
Real-time snowpack modeling
7
Landscape model (snowpack) helps inform decision on when to release bison Optimal time for release?
8
The cold face of collaboration
9
Landscape inputs to wildlife studies Pr( Use of location by species ) = f ( Landscape covariates,,,Temporal covariates,,, )
10
Landscape inputs to wildlife studies Probability of bison corridor travel (Bruggeman et al., submitted)
12
Some false positives Probability of bison corridor travel (Bruggeman et al., submitted)
13
Bison distribution & landscape covariates Vegetation Slope Snowpack
14
Bison utilization distribution: Habitat-selection analysis using standard Resource Selection Functions (RSFs)
15
Two paradigms 1.Pr( Use ) = f ( Landscape covariates ) 2.Pr( Use ) = f (Distance to previous locations)
16
Two paradigms
17
A new approach: Selective Computational Diffusion (SCD) Pr( Use here ) = Pr( Use next door ) * f ( Landscape here ) Iterated many times (computationally demanding)
18
Comparison of approaches
19
Taking SCD out on the road (so to speak!) --- Observed movement --- Predicted movement
