Research interests: Basic and applied aspects of restoration ecology to restore the functionality of and mitigate impacts to forest and rangeland wildlife habitats following disturbance.
Research interests: Isotope ratio mass spectrometry, including method development, quality control and quality assurance, and teaching.
Research interests: Revegetation of wildland disturbances such as mined lands and on areas impacted by exotic invasions and wildfire, improvement of productivity and revegetation effectiveness to enhance wildlife habitat and understand the mechanisms that contribute to and limit exotic invasions.
Research interests: spatial and temporal patterns of selection in plant populations using techniques in field ecology, molecular genetics and bioinformatics, adaptation of plant populations to local environments, and the implications of local adaptation for the restoration of native plant communities.
Research interests: measurement and modeling of watershed-to-landscape scale processes, use of GIS in process-based spatially distributed hydrologic modeling, fluvial geomorphology, development of landscape metrics for land cover change and habitat evaluation, Spatial Analysis of Watershed and Landscape Systems Group.
Research interests: ecosystem biodiversity, ecological and anthropogenic processes and how they constrain species distributions, functional connectivity and how it limits population persistence, landscape change and impact of alternative future landscape conditions on ecosystem sustainability.
Research interests: Watershed and rangeland hydrology, measurement and modeling hydrologic processes, watershed and land use management decision tools, effects of fire on rangeland hydrologic and erosion processes, characterization of soil hydraulic properties, soil moisture measurement, ecological site characterization and monitoring
Research interests: environmental chemistry watershed land use activities (e.g., energy industry and ag production), sustainability of natural resources (e.g., air quality and water quality).
Research interests: rangeland plant identification, poisonous plants and toxins, and ecological applications for wildland management
Research interests: Interactions and impacts of herbivores on rangeland ecosystems and relationships of ecological condition and forage production for domestic livestock, wildlife habitat attributes, insects and invasive plant species
Research interests: rangeland sustainability, including ecological functioning of rangelands, economic values and decision-making, rangeland-dependent communities and families, Sustainable Rangelands Roundtable.
Research interests: nutrition and management problems and questions concerning livestock operations, feeding and management program development with 4-H, information dissemination.
Research interests: plant-environment interactions in terrestrial environments of the world with particular focus on savannas, grasslands and deserts, potential responses of water-limited ecosystems to changes in climate, atmospheric chemistry and vegetation composition.
