Convergence of trophic state and the lower food web in Lakes Huron, Michigan and Superior
TL;DR: Signs of increasing oligotrophication have been apparent in the open waters of both Lake Huron and Lake Michigan in recent years as discussed by the authors, consistent with decreases in productivity, leading to a distinct convergence of the trophic state and lower food web in the three lakes.

The Deep Chlorophyll Maximum in Lake Superior
TL;DR: Summer surveys conducted on Lake Superior from 1996–2001 indicated that a deep chlorophyll maximum (DCM) is a common feature of the offshore waters, and phytoplankton communities at the level of the DCM were taxonomically distinguishable from those in the epilimnion, with the most notable difference being a relative reduction in the abundance of Cyclotella species.

Results from the U.S. EPA's Biological Open Water Surveillance Program of the Laurentian Great Lakes: III. Crustacean Zooplankton
TL;DR: Open water zooplankton communities were sampled across all five Laurentian Great Lakes during spring and summer 1998 as discussed by the authors, and the results showed that the upper lakes were dominated by diaptomid copepods, cyclopoid copepodites, and Daphnia galeata mendotae (codominant with Holopedium gibberum in Lake Superior).

Recent increases in the large glacial-relict calanoid Limnocalanus macrurus in Lake Michigan.
TL;DR: Since 2004, population density of the large hypolimnetic calanoid Limnocalanus macrurus Sars has increased dramatically in Lake Michigan The average summer biomass of this species between 2004 and 2006 was roughly three times that of the period 1984-2003, and at levels unprecedented in our 22-year dataset, making L macrures the dominant zooplankter in the lake in terms of biomass.

TL;DR: An annotated checklist of the free-living copepods of the Laurentian Great Lakes is developed on the basis of published records, relating, wherever possible, invalid names in the literature with currently recognized taxonomy.
