FRESHWATER INVERTEBRATES

BIOLOGY 542/742

COURSE SYLLABUS



COURSE OBJECTIVES:  This course is designed to teach students about the life history and ecology of freshwater invertebrates. The lecture will stress these aspects while the lab will stress learning where these organisms live, how to collect, preserve and identify them. The lab will also stress the professional curation of aquatic invertebrates and to that end a collection will be required.

GRADING:


There will be two lab practicals and two lecture exams. In addition each student will be required to make a collection; undergraduates are to turn in 50 taxa and graduate students will turn in 75 taxa. Each exam will have equal weight; the collections will count for one exam; it will be due Dec. 3. Each student will also turn in a 5-7 page paper on the natural history of a selected taxon; it will be due Nov. 19. The paper will be worth one exam grade. All grades will be averaged, and final grades will be based on the 90-100=A, 80-89.5=B; 70-79.5=C, 60-69.5=D; below 60=F grade scale.



Field Trips:


There will be several field trips that all students are required to attend. These will provide be invaluable experience and should not be missed. They will also provide an opportunity for students to collect specimens for their collections, and see the organisms in their natural environment. They are scheduled for Sept. 5, Sept, 19-21, and Oct. 10-13. These trips will be combined with the Ichthyology class, and should be a lot of fun as well as memorable learning experiences.
