Marney Pratt

Ph.D. Laboratory Instructor in Biological Sciences

Marney Pratt


Sabin-Reed Hall 249


When she was young, Pratt spent summers in Maine playing in a freshwater lake, which likely began her love of ecology and all things aquatic. During college, graduate school and postdoctoral work, her research focused in the field of biomechanics and physiological ecology in marine intertidal organisms, including red algae, bryozoans, nudibranchs and sea stars.  Since joining the Smith College Department of Biological Sciences, Pratt has started exploring local ecological and environmental issues in her teaching and research. In particular, she is involved in research monitoring the health of the Mill River using freshwater macroinvertebrates to assess how Smith College’s sediment management of Paradise Pond might influence the river. Other projects include investigating invasive pests on hemlock trees and monitoring when leaves open in the spring in invasive and native shrubs.  She currently teaches several laboratory sections of Biodiversity, Ecology, and Conservation and Animal Physiology. In both courses, she uses course-based research to help students learn through authentic research experiences.
