NOAA Great Lakes Seminar Series Seminar Announcements
(Posted by David Reid, GLERL)

Date:  Tuesday, December 4, 2001

TITLE: "ECOSYSTEM RESTORATION OF LAKE OKEECHOBEE, FLORIDA"

SPEAKER: Dr. Alan Steinman
Director, Annis Water Resources Institute, Lake Michigan Center, Grand 
Valley State University.

TIME: 1:00 p.m.

WHERE: GLERL Main Conference Room

ABSTRACT: Lake Okeechobee (Florida) is the second largest freshwater lake 
in the coterminous United States (after Lake Michigan). It is impacted 
primarily by three environmental problems: cultural eutrophication, altered 
hydrology, and invasive species. A major restoration program, consisting of 
experimental research, modeling, planning, construction, and regulatory 
activities, was initiated in the late 1990s and is expected to last for 
several decades. This talk provides an overview of these problems and the 
proposed restoration activities, highlights a case study revealing the 
political difficulties of integrating science and environmental management, 
and shows an example of how an episodic event (Hurricane Irene) strongly 
influences the dynamics of this large, shallow subtropical lake.

TITLE: "GENETIC INVESTIGATIONS OF NONINDIGENOUS SPECIES INVASIONS IN THE 
GREAT LAKES: ORIGINS, GENETIC DIVERSITY, AND SPREAD PATTERNS OF DREISSENID 
MUSSELS, GOBIES, AND THE RUFFE"

SPEAKER: Dr. Carol Stepien (Sea Grant scientist)
Director, Great Lakes Environmental Genetics Laboratory, Center for 
Environmental Science, Technology and Policy, Cleveland State University.

TIME: 2:00 p.m.

WHERE: GLERL Main Conference Room

ABSTRACT: Population genetic relationships for three nonindigenous species 
invasions in the Great Lakes are analyzed from nuclear and mitochondrial 
DNA sequence data for zebra and quagga mussels, round and tubenose gobies, 
and the Eurasian ruffe. Comparisons are made across their respective native 
and introduced ranges. Results indicate that zebra mussels appear to have 
been introduced from multiple sites in central and western Europe, but not 
eastern Europe; quagga mussels in North America are divergent from samples 
in their native Ukraine; introduced populations of round gobies in North 
America and Gulf of Gdansk had different founding sources and neither are 
related to the northern Black Sea; and the ruffe invasion in North America 
originated from a single source that matches the Elbe River.
