Lake Texoma

Invasive Species in Fresh Waters
Undergraduate/Graduate Course for Spring 2009

Advanced Topics in Limnology (Zoology 4673/5673)
Credit: 3 hours
Instructor: Dave Hambright
Time/Place: Wednesdays at 9-11:30 a.m. / 312 Sutton Hall

Limnology is the study of inland waters, and extends across a variety of scientific disciplines (biology, chemistry, ecology, evolutionary biology, physics, and geology). This course is designed to allow students who have previously taken Ecology of Lakes, Stream Ecology or an equivalent course in other biological or environmental sciences to gain a more detailed understanding within focused topics in limnology.

The topic of ATL this spring will be “Invasive species in fresh waters.” An invasive species is a non-indigenous species that colonizes a new system and dramatically alters the ecology of that system. During the past quarter century we have witnessed an explosion of species invasions in aquatic systems. Recent examples of invasive species in Oklahoma include zebra and quagga mussels (Dreissena polymorpha and D. rostriformis) from the Black and Caspian Seas, Asian “bighead” carp (Hypophthalmichthys nobilis), African waterfleas (Daphnia lumholtzi), and the toxigenic marine golden alga (Prymnesium parvum). Although we will deal primarily with aquatic systems, students with more terrestrially-based backgrounds are encouraged to take the challenge of examining ecology below the water’s surface.

Class meetings will be split between instructor- and student-led discussions of historicl and current literature. Students also will develop either a research project proposal or a brief literature review (depending on the size of the class) relating to invasive species and make an in-class presentation. The semester will begin with discussion of two important texts: Elton (1958) The Ecology of Invasions by Animals and Plants and Lockwood et al. (2007) Invasion Ecology; the second third of the class will be concentrated on case studies of aquatic invasives taken from the primary literature; and the last third of class will be devoted to development of proposals/reviews and presentations.

Student grades will be based on class participation (50%), proposal/review (25%) and presentation (25%).

PREREQUISITES: Ecology of Lakes (Zoo 4463), Stream Ecology (Zoo 4423), or with permission.
