A review of the evolutionary origins, adaptations, and trends in the biology of vertebrates. Laboratory (BIO 273) is recommended but not required. No Prerequisites.

This lab introduces students to plant morphology and identification through hands-on work with plant material. In addition, we focus on local native plants and the outstanding botanical collections in the Lyman Plant House. Field trips to other sites of botanical interest in the region are also taken. Corequisite: BIO 264. Enrollment limited to 20.

This course explores the diversity of plant life and investigates its evolutionary origins and history through a mixture of lecture, lab and discussion activities. A key focus of the course is the ecological and environmental context of major evolutionary developments in the Land Plants, including their adaptations to various abiotic challenges, as well as antagonistic and mutualistic interactions with other organisms. Our survey of plant diversity is guided by recent phylogenetic studies and we make use of the outstanding living collections in the Lyman Plant House. Prerequisite: BIO 264.

This laboratory examines relationships between invertebrate form and function and compares diversity within and among major body plans using live and preserved material. Students observe and document invertebrate structure, life cycles, locomotion, feeding and other behaviors. Corequisite: BIO 260. Enrollment limited to 20.

Invertebrate animals account for the vast majority of species on earth. Although sometimes inconspicuous, invertebrates are vital members of ecological communities. They provide protein, important ecosystem services, biomedical and biotechnological products, and aesthetic value to humans. Today, many invertebrate populations are threatened by human activities. This course surveys the extraordinary diversity and importance of invertebrates, emphasizing their form and function in ecological and evolutionary contexts. Corequisite: BIO 261. Enrollment limited to 20.

A laboratory designed to complement the lecture material in 230. Laboratory and computer projects investigate methods in molecular biology including PCR, restriction analysis and DNA sequencing as well as contemporary bioinformatics, data mining and the display and analysis of genome databases. Corequisite: BIO 230. Enrollment limited to 16.
