FYSM 100 First-Year Seminar
The First-Year Seminar (FYS) introduces students to Dickinson as a "community of inquiry" by developing habits of mind essential to liberal learning. Through the study of a compelling issue or broad topic chosen by their faculty member, students will: - Critically analyze information and ideas - Examine issues from multiple perspectives - Discuss, debate and defend ideas, including one's own views, with clarity and reason - Develop discernment, facility and ethical responsibility in using information, and - Create clear academic writing The small group seminar format of this course promotes discussion and interaction among students and their professor. In addition, the professor serves as students' initial academic advisor. This course does not duplicate in content any other course in the curriculum and may not be used to fulfill any other graduation requirement.

BIOL 129 Changing Ocean Ecosystem W/Lab
An introduction to the biology of marine communities, including salt marshes and mangroves, intertidal zones, reefs, and deep-sea vents, among others. For each community, the physical characteristics of the environment as well as the physiological adaptations of the resident species will be examined. We will also focus on how marine communities are changing in response to anthropogenic stresses in light of concepts such as diversity indexes, keystone species, and disturbance theory. Selected readings from the primary literature and the popular press are required. Laboratory projects will emphasize experimental design and hypothesis testing. Three hours classroom and three hours laboratory a week.
