Distribution of Rotifera and Cladocera in a regulated river system
… of this study was to determine distributions of Rotifera and Cladocera in the Kanawha River in West Virginia. Rotifera were sampled monthly for twelve months with a Juday trap in the more lotic upstream end of Winfield pool (UW), and the more lentic downstream end of Winfield pool (LW) to …

The distribution and dynamics of planktonic rotifera in the North Island, New Zealand
The distribution and dynamics of planktonic rotifers, at various spatial and temporal scales, were investigated in lakes of the North Island, New Zealand. The overall aim was to provide a better understanding of the relative influence of various environmental gradients in determining the …

OVERLOOKED AND UNDERSTUDIED: A SURVEY OF THE SMALL AND HIDDEN FRESHWATER INVERTEBRATE TAXA (PHYLUM ROTIFERA AND SUBPHYLUM CRUSTACEA)
During a 2018 parasitic crustacean survey of Oneida Lake, four adult female specimens of the Asiatic parasitic copepod Neoergasilus japonicus (Harada, 1930) were collected, one specimen was from a white sucker (Catostomus commersonii), another from a green sunfish (Lepomis cyanellus), and two from …

Invertebrate Fauna of the Carapaces of the Texas River Cooter (Pseudemys texana) and the Red-Eared Slider (Trachemys scripta elegans)
… invertebrates identified included species of Rotifera, Nematoda, Crustacea, Gastropoda, Insecta, and Hirudinea. A comparison of the similarity and diversity of invertebrates on the carapaces of P. texana and T. s. elegans revealed similar communities. A positive correlation occurred between …

Structure and function of zooplankton colonization in twelve new experimental ponds
… data were pooled into taxa (Copepoda, Cladocera, Rotifera, ostracoda and Chaoborus) and analyzed. Rotifers dominated zooplankton communities in densities and biomass, and ponds differed in taxa densities and biomasses. Zooplankton community function was more similar among ponds than community …

Abundance, Standing Stock Biomass and species Composition of Zooplankton in Lake Sakakawea, ND and Uptake of Dissolved Organic Carbon (DOC) by Daphnia pulex
… including 12 Copepoda, 19 Branchiopoda and 31 Rotifera. Mean annual zooplankton abundance was greatest at Van Hook Arm (216.2/l; n = 65; CV= 75.6%), and at White Earth (205.7 /l; n = 66; CV= 81.5%). Abundance was lowest at Wolf Creek near Garrison Dam (65.8/1), and also the least variable (n = …

The ecology of larval and juvenile fishes in lowland rivers, with particular emphasis on foraging
… in some species, for example, densities of Rotifera in the margins declined at night, suggesting migration into open waters. Densities of 0+ fishes were generally higher at night in three surveys, but higher in daylight in two surveys. This may have been a result of predator avoidance as …
