Spatial patterns in population trends of the amphipod Diporeia spp. and Dreissena mussels in Lake Michigan

The thermal variability of the waters of Fathom Five National Marine Park, Lake Huron

“…Similarly Fitzsimons et al (2002) attributed the absence of crayfish at sampling sites due to the thermal stress associated with frequent upwelling of cold water. Nalepa et al (2005) reported greater abundance of the benthic amphipod Diporeia spp. on the west side of Lake Michigan where upwelling brings colder more enriched waters.…”

Distribution of circular single‐stranded DNA viruses associated with benthic amphipods of genus Diporeia in the Laurentian Great Lakes

“…Finger Lakes benthic communities in central New York; Watkins et al., ). Hypotheses attributing changes in Diporeia abundance to niche displacement and bivalve‐imposed food limitation (either through the interception of detrital deposits or mitigation of calcite‐dependent phytoplankton blooms) have been refuted both in situ and in mesocosm trials (Dermott, Bonnell, & Jarvis, ; Nalepa, Fanslow, & Foley, ; Nalepa et al., ; Ryan, Sepúlveda, Nalepa, & Höök, ; Watkins et al., ). Diporeia population densities are also poorly associated with variation in lake productivity, benthic flux of organic carbon and fish predation (Watkins et al., ).…”

Acanthocephalan Parasites of Slimy Sculpin, Cottus cognatus, and Ninespine Stickleback, Pungitius pungitius, from Lake Michigan, U.S.A

“…Diporeia hoyi has recently been declining in some areas in Lake Michigan, and its decline is hypothesized to be due to the establishment of zebra mussels Dreissena polymorpha (see Nalepa et al, 2005Nalepa et al, , 2009. Perhaps a switch in diet of C. cognatus due to a reduction in the number of D. hoyi at MS accounts for the numerical results observed for infrapopulations in these acanthocephalan species.…”
