Teaching next semester

BIOL 2232/ENVS 2232. Benthic Ecology

The principles of ecology emphasizing the hard- and soft-bottom communities of Casco Bay and Harpswell Sound. Field trips and field exercises demonstrate the quantitative principles of marine ecological research, including good practices in sampling designs and field experiments. A class field project designs and implements a long-term study, based at the Bowdoin Marine Laboratory, to monitor and detect changes in community structure driven by climate change in the twenty-first century. Assumes a basic knowledge of biological statistics. Taught in residence at the Bowdoin Marine Laboratory, Biology 2232/Environmental Studies 2232 is a course-module in the Bowdoin Marine Science Semester. Biology 2501 (same as Environmental Studies 2231), Biology 2330 (same as Environmental Studies 2233), and English 2804 (same as Environmental Studies 2804) are co-requisites of this course.

BIOL 2330/ENVS 2233. Marine Molecular Ecology and Evolution

Features the application of molecular data to ecological and evolutionary problems in the sea. Hands on laboratory work will introduce students to sampling, generation, and analysis of molecular data sets with Sanger-based technology and Next Generation Sequencing. Lectures, discussions, and computer-based simulations will demonstrate the relevant theoretical principles of population genetics and phylogenetics. A class project will begin a long-term sampling program that uses DNA barcoding to understand temporal and spatial change in the ocean. Taught in residence at the Bowdoin Marine Laboratory, Biology 2330/Environmental Studies 2233 is a course-module in the Bowdoin Marine Science Semester. Biology 2232 (same as Environmental Studies 2232), Biology 2501 (same as Environmental Studies 2231), and English 2804 (same as Environmental Studies 2804) are co-requisites of this course.

BIOL 2501/ENVS 2231. Biological Oceanography

Features classroom, laboratory, and fieldwork emphasizing fundamental biological processes operating in pelagic environments. It includes a hybrid of topics traditionally taught in physical and biological oceanography courses: major ocean current systems, physical structure of the water column, patterns and process of primary production, structure and function of pelagic food webs. Field trips to Casco Bay and Harpswell Sound will introduce students to the methods and data structures of biological oceanography. Taught in residence at the Bowdoin Marine Laboratory, Biology 2501/Environmental Studies 2231 is a course-module in the Bowdoin Marine Science Semester. Biology 2232 (same as Environmental Studies 2232), Biology 2330 (same as Environmental Studies 2233), and English 2804 (same as Environmental Studies 2804) are co-requisites of this course.

ENGL 2804/ENVS 2804. Maine Writers and the Environment

Explores the wild and diverse literary territories of the state of Maine-past and present-with a focus on coastal narratives and environmental writing. Considers Maine's multi-ethnic folkways, its austere modernisms, remorseless gothic landscapes, natural splendors and antagonisms, coastal rhapsodies and adversities, and contemporary environmental imperatives. Includes poetry, short stories, novels, memoirs, personal narratives, children's literature, nature writing, and environmental advocacy by such writers as Thoreau, Jewett, Robinson, Millay, Beston, Carson, McCloskey, King, Russo, Strout, and Bryan. Taught in residence at the Bowdoin Coastal Studies Center. English 2804/Environmental Studies 2804 is a course-module in the Bowdoin Marine Science Semester. Biology 2232 (same as Environmental Studies 2232), Biology 2330 (same as Environmental Studies 2233), and Biology 2501 (same as Environmental Studies 2231) are co-requisites of this course.
