This course is an exploration of the local invertebrate fauna at Hopkins Marine Station, through the lens of a long-term monitoring study initiated by Hewatt in 1931. During week 1, lectures will provide an overview of the major phyla represented on rocky intertidal shores. In the laboratory, students will focus on species identification. These skills will be put to use in week 2, when we will quantify patterns of invertebrate biodiversity along the Hewatt transect. During week 3, students will investigate a relevant taxonomic or quantitative problem. This course will meet 12-5pm, Monday-Friday. January 13-31, 2020. Open to graduate students; undergraduate students may enroll with consent of instructor.
