This project examines the social relations of power, knowledge, and technology that are involved in establishing carbon offsets among indigenous smallholders in Costa Rica. It examines how complex agricultural practices are interpreted by scientists and economists in the process of creating a carbon "price tag" for land use changes, and the resulting impacts of this process on indigenous land use and livelihoods.

This project examines the effectiveness of Costa Rica's long–running payments for ecosystem services program among smallholders. It does so by testing whether state payments are producing additional forest cover or subsidizing status quo patterns of reforestation. It also examines the role of various other state institutions in encouraging forms of fallow management in ways that create potential sites where PES can be additional. Doing so, this project contextualizes PES outcomes within historically and geographically complex state–peasant relationships.

This research project developed a fuzzy cellular automata model based on the subpixel fractions extracted from multitemporal satellite images and discusses the relationship between sophisticated remote sensing techniques and an urban process model within the socioeconomic dimension. The major objectives include incorporating the subpixel membership derived from remote sensing images into fuzzy cellular automata model and calibrate this subcell urban landscape models.

This research project identified economic and ecological function of urban greenness and to examine how they changed during the urbanization in Baltimore-Washington corridor area in recent 20 years. We investigated the vegetation pattern and change, identify the role of urbanization in the change of biophysical parameter of urban tree through field measurement and advanced remote sensing techniques.

The third phase of the Baltimore Ecosystem Study builds on 13 years of experience in establishing a platform for integrated urban ecological and social research, education, and outreach. BES III takes advantage of the growing shift of urban areas toward sustainability policies, and the need to scientifically understand and evaluate the adaptive processes proposed to promote urban sustainability.

This is a study of lightning frequency mapped to the physiographically diverse landscape of Chesapeake Bay – urban corridor – Blue Ridge mountains, using a high resolution lightning detection and mapping system. The goal is to ascertain whether lightning intensity is related to the anthropogenic landscape, through generation of local meteorological boundaries and/or high concentration of air pollutants.

Hurricane intensity change remains poorly forecast, compared to track and landfall location. For decades, NASA has used a combination of satellites and high altitude research aircraft to study the physics of tropical cyclones, with the goal of better understanding the genesis and rapid intensification of Atlantic basin storms. Our research examines the relationship between eye wall thunderstorms, intense lightning and the warm core of the storm's eye.

Research is focused on the evolution of public lands in the United States with particular interest in the role the federal government played in the establishment of state park and forest lands in the 20th century. In part, the research explores the tension between conservation and preservation in the early to mid 20th century.
We are studying stream restoration practice as a foundation to understand how spatial position in river networks mediates the relative role of local (e.g., habitat features) and regional (e.g., dispersal) factors drive local species composition, and turnover in composition across stream reaches.

Management of urban stormwater detention ponds involve meeting multiple goals, including reducing runoff, attenuating stormflow, and in residential contexts, aesthetics. Since these features are rapidly replacing wetlands in the built environment, we are investigating the ecological structure and function of these novel habitats compared to their native counterparts.

Ecosynth is a system that ecologists can use to make 3D scans of vegetation structure and potentially species at their own study sites at a relatively low cost. This approach uses computer vision software to enable personal, user–based remote measurement of ecosystems comparable to what can be accomplished with satellite or airplane based technology, but with the use of off-the-shelf digital cameras and low to high grade hobbyist remote controlled aircraft.

Biotic consequences of watershed urbanization are typically assessed using space-for-time substitutions. We are building a 25-year 'space-time stack' of impervious surface expansion in the Baltimore-Washington metropolitan area from satellite imagery and seeking evidence of coincident chemical and biotic changes in stream monitoring data across more than 100 sampling locations.

Over the past 100 years, several species of exotic trout have been introduced to a large, ultra-oligotrophic Andean lake. However, surveys suggests that these species have differentially and unevenly colonized many tributaries. Our research seeks to understand how ecological and physical processes contribute to observed distributions and their evolutionary consequences.
