The eutrophication of freshwaters is a global health concern as lakes with excess nutrients are often subject to toxic cyanobacterial blooms. Although phosphorus is considered the main element regulating cyanobacterial biomass, nitrogen (N) concentration and more specifically the availability of different N forms may influence the overall toxicity of blooms. In this study of three eutrophic lak...
There is debate about whether results from mesocosm studies should be extrapolated to natural ecosystems. Critics argue that the abiotic and biotic characteristics of mesocosms do not represent the in situ conditions of the habitats in which they are designed to mimic. We addressed this idea by deploying mesocosms in two lakes of varying trophic status (mesotrophic and eutrophic). Water chemist...
Index words: Management Hydrodynamics History Recreation Fisheries Cormorants Lake Champlain shares a geological history with the Great Lakes and, as part of the St. Lawrence drainage, also shares biological and ecological similarities. The complex bathymetry and extensive shoreline provide a variety of lacustrine habitats, fromdeep oligotrophic areas to shallowbays that are highly eutrophic. T...
