Shana Stewart Deeds

Laboratory Instructor in Biology and Environmental Studies

Teaching this semester

BIOL 1158/CHEM 1105/ENVS 2201. Perspectives in Environmental Science, L1

Understanding environmental challenges requires scientific knowledge about the different spheres of the Earth -- land, water, air, and life -- and how they interact. Presents integrated perspectives across the fields of biology, chemistry, and earth and oceanographic science to examine the scientific basis for environmental change from the molecular to the global level. Foundational principles are developed to address major course themes, including climate change, energy, soil/air/water pollution, chemical exposure and risk, land use change, and biodiversity loss. Laboratory sessions consist of local field trips, laboratory experiments, group research, case study exercises, and discussions of current and classic scientific literature.

Teaching next semester

BIOL 2327/ENVS 2227. Ecology, L1

Ecology, the study of how organisms interact with each other and their environment, incorporates topics from how organisms cope with environmental stressors to global carbon cycling. Addresses current questions in ecology, from global change to food security to invasive species. Lectures, labs, primary, and popular literature emphasize how scientists use the tenets of ecology to address current environmental issues. Labs, excursions, and student research include ecological studies of plant-insect interactions, collection of long-term data on salamander populations, and emphasis on the natural history of mid-coast Maine. Students have the opportunity to take an optional field trip to the Bowdoin Scientific Station on Kent Island in the Bay of Fundy.

Whenever possible, Shana tries to get out in the field to explore Maine’s ecology with Bowdoin students. Her predominant course load includes BIOL 2315 - Behavioral Ecology and Population Biology and ENVS 2201 - Perspectives in Environmental Science.

Before coming to Maine, Shana lived in Vermont where she taught biology and environmental science courses and coordinated the efforts to get the Missisquoi and Trout Rivers nationally designated as Wild and Scenic Rivers – the first designated rivers in the state ( Her career interests have always centered on ecology and education, with particular interests in amphibians and reptiles, water quality and agriculture. Her diverse jobs have taken her from farming in Purcellville, VA to conducting ecological surveys with the PA Natural Heritage Program, and from researching river resources in VT to educating students at Smokey House Center (a VT alternative education program).
