Research Projects

Regional NPP and Carbon Stocks in Southwestern USA Rangelands: Land-use Impacts on the Grassland-Woodland Balance: Historical and on-going woody plant proliferation in the world’s extensive dryland ecosystems may have significant implications for the global carbon cycle. Factors contributing to these ecosystem transitions are ...

Disturbance Dynamics in Subalpine Forest: Ecological theory suggests that succession becomes increasingly unpredictable as disturbance intensity increases. If disturbances occur in rapid succession, regeneration patterns and mechanisms are much less predictable than after a single disturbance and novel successional pathways are possible. Increasingly, ecosystems are exposed to multiple disturbances as human land management practices fold into natural disturbance regimes, perhaps magnifying system-scale stresses.


World Deltas Network: A data, information, and research support service for deltas, to advance integrated science in the coastal zone, spanning physical, biological, and sociological disciplines.


Architecture for Modeling Ecological Functions: A "proof of concept" demonstration to map an invasive macro-algae problem in Hawaii and vegetation distribution in India. Ecological Niche Modeling is built on a standard ecological basis (reduction to the ideal Gaussian response). The basic ideas apply a theoretical decomposition mathematical equation into sub Gaussians (similar to a Fourier analysis).

Social-ecological Systems in Urban Environments: Urban ecosystems depart from the regional native ecosystems in which they reside. In a sense, they are new ecological systems, with complex and broad-ranging resource demands and socioeconomic forces absent in the original 'wild' environment.
