Landscape and Ecosystem Ecology
Ecosystem ecology, landscape ecology, regional and global biogeochemical cycling, ecological applications of remote sensing and geographic information systems
Our research program seeks to gain insights on feedback dynamics between ecosystem structure and function, and the influence of disturbance on trajectories of ecosystem processes. Our research approaches involve field studies, remote sensing methodologies investigating temporal and spatial heterogeneity in ecosystem properties, and landscape and ecosystem modeling. We incorporate theory in ecosystem and landscape ecology, with a recent emphasis on resilience and complex system theory. Current research projects include: biogeochemical dynamics of woody plant encroachment in the US Southwest, resilience of forest ecosystems under compound disturbance, and social-ecological systems in urban environments.

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.
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...
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.
