Experiments in Developmental and Molecular Genetics

Experimental approaches in devel- opment and genetics using animal and plant models. Laboratory training in molecular genetics, immunochemistry, microscopy, protein chemistry, and genetic screening. Experiments include immunochemical localization, in situ hybridization, polymerase chain reaction, genetic screening, embryo micromanipulation, microscopic imaging, and mutant analysis. Prerequisite: Biology 201L or 202L; recommended, prior or concurrent registration in Biology 220. One course.

Sensory Signal Transduction

Recent progress in sensory signal transduction mediated by calcium channels and receptors. Topics include history and techniques in the study of ion channels, such as electrophysiology, calcium imaging, and cell and molecular biology; cell surface perception for external signals, including light receptors, olfactory receptors, taste receptors, hot and cold receptors, and mechanical receptors; heart and brain pacemakers; sensory channel receptor-related human diseases; and plan sensory signaling network. One course.

Marine Invertebrate Zoology

Structure, function, and development of invertebrates collected from estuarine and marine habitats. Not open to students who have taken Biology 777LA. One course. (Given at Beaufort fall, spring, and summer.) Prereq- uisite: AP Biology or introductory biology or consent of instructor. Variable credit.

Marine Mammals

Laboratory version of Biology 376A. Laboratory and field exercises consider social organization, behavior, ecology, communication, and anatomy of local bottlenose dolphins. (Given at Beaufort.) Prerequisite: introductory biology. One course.

Marine Mammals

The biology of cetaceans, pinnipeds, sirenians, and sea otters. Topics covered include the diversity, evolution, ecology, and behavior of marine mammals and their interactions with humans. Detailed consideration given to the adaptations that allow these mammals to live in the sea. Evaluation of the scien- tific, ethical, and aesthetic factors influencing societal attitudes toward these animals and of their conservation management in light of domestic legislation and international treaties. (Given at Beaufort.) Prerequisite: introductory biology. One course.
