2003, Journal of Great Lakes Research (29) 137-151
Before 1995, Great Lakes streams were selected for lampricide treatment based primarily on qualitative measures of the relative abundance of larval sea lampreys, Petromyzon marinus. New integrated pest management approaches required standardized quantitative measures of sea lamprey. This paper evaluates historical larval assessment techniques and data and describes how new...
Effects of two classification strategies on a Benthic Community Index for streams in the Northern Lakes and Forests Ecoregion
Jason T. Butcher, Paul M. Stewart, Thomas P. Simon
2003, Ecological Indicators (3) 195-202
Ninety-four sites were used to analyze the effects of two different classification strategies on the Benthic Community Index (BCI). The first, a priori classification, reflected the wetland status of the streams; the second, a posteriori classification, used a bio-environmental analysis to select classification variables. Both classifications were examined by measuring...
Passage of four teleost species prior to sea lamprey (Petromyzon marinus) migration in eight tributaries of Lake Superior, 1954-1979
Gregory L. Klinger, Jean V. Adams, John W. Heinrich
2003, Journal of Great Lakes Research (29) 403-409
Seasonally operated barriers in rivers are used by the Great Lakes Fishery Commission to block adult sea lamprey (Petromyzon marinus) migrations, yet pass other fish during some part of the year. Knowledge of the overlap of spawning migrations of sea lampreys and other fish species are vital for the efficient...
