Dispersal and emerging ecological impacts of Ponto-Caspian species in the Laurentian Great Lakes.
We describe, explain, and "predict" dispersal and ecosystem impacts of six Ponto-Caspian endemic species that recently invaded the Great Lakes via ballast water. The zebra mussel, DreissenaExpand

Zebra mussel (Dreissena polymorpha) selective filtration promoted toxic Microcystis blooms in Saginaw Bay (Lake Huron) and Lake Erie
Microcystis aeruginosa, a planktonic colonial cyanobacterium, was not abundant in the 2-year period before ze- bra mussel (Dreissena polymorpha) establishment in Saginaw Bay (Lake Huron) but becameExpand

Transformation of the offshore benthic community in Lake Michigan: recent shift from the native amphipod Diporeia spp. to the invasive mussel Dreissena rostriformis bugensis
SUMMARY 1. The native amphipod Diporeia spp. was once the dominant benthic organism in Lake Michigan and served as an important pathway of energy flow from lower to upper trophic levels. Lake-wideExpand

Declines in benthic macroinvertebrate populations in southern Lake Michigan, 1980-1993
Densities of the major benthic macroinvertebrate groups declined dramatically at sites shallower than 50 m in southern Lake Michigan between 1980 and 1993. Declines in Diporeia, Oligochaeta, andExpand

Recent Changes in Density, Biomass, Recruitment, Size Structure, and Nutritional State of Dreissena Populations in Southern Lake Michigan
ABSTRACT Trends in density, biomass, population structure, and nutritional state of Dreissena polymorpha and Dreissena rostriformis bugensis were examined in southern Lake Michigan between the 1990sExpand

Effects of Zebra Mussel (Dreissena polymorpha) Colonization on Water Quality Parameters in Saginaw Bay, Lake Huron
Abstract A large-scale study of Saginaw Bay was initiated in 1990 and continued through 1993 to examine the effects of the zebra mussel colonization which began in summer/fall 1991. Saginaw BayExpand

Dreissena and the Disappearance of the Spring Phytoplankton Bloom in Lake Michigan
ABSTRACT We determined the clearance rates of the profunda morph of the quagga mussel (Dreissena bugensis) using seston and Cryptomonas ozolini, a high-quality algal food, for the temperature rangeExpand

Continued disappearance of the benthic amphipod Diporeia spp. in Lake Michigan: is there evidence for food limitation?
Benthic surveys were conducted in the southern basin of Lake Michigan and throughout the lake to assess trends in benthic populations, emphasizing recent changes in densities of the benthic amphipodExpand

Long-term Trends in Benthic Macroinvertebrate Populations in Lake Huron over the Past Four Decades
ABSTRACT Surveys of the benthic macroinvertebrate community were conducted in the main basin of Lake Huron in 2000 and 2003, and in Georgian Bay and North Channel in 2002. Results were compared toExpand
