Teaching

EFB 445/645 Plant Ecology (3 credit hours). Two hours of lecture and discussion one laboratory session. A first course in plant community ecology dealing with the dynamics of community development and change and the process of community analysis and description.

EFB 535 Systematic Botany (3 credit hours). Two hours of lecture, three hours of laboratory. Identification, nomenclature, and classification of flowering plants with special emphasis on local flora and developing the ability to classify plants in any region.

  • Course Syllabus
  • Lecture Schedule

EFB 496 Functional Ecology of Adirondack Communities (participant). Experimental, interdisciplinary, or special coursework in biology for undergraduate students. Subject matter and methods of presentation varies from semester to semester.

Research Interests

Investigations in my research group focus on plant population, community and ecosystem ecology. Topics currently being pursued include the ecology and control of invasive plants, historical patterns of forest tree growth, the role of forest herbs in biogeochemical cycling, the influence of nitrogen fixing shrubs on nitrogen dynamics in Adirondack surface waters, characterization of Adirondack wetland ecosystems, relationships between forest condition and water quality in the Catskill Mountains, and influences of atmospheric deposition on Adirondack forests.
