Responses of bluegills and black crappies to dissolved oxygen, temperature, and current in backwater lakes of the upper Mississippi River during winter Responses of bluegills and black crappies to dissolved oxygen, temperature, and current in backwater lakes of the upper Mississippi River during winter
We conducted a radiotelemetry study to examine the effects of dissolved oxygen (DO), water temperature, and current velocity on winter habitat selection by bluegills Lepomis macrochirus and black crappies Pomoxis nigromaculatus in the Finger Lakes backwater complex, Pool 5, on the upper Mississippi River. When DO was above 2 mg/L, both species selected areas with water temperature...

Improving electrofishing catch consistency by standardizing power Improving electrofishing catch consistency by standardizing power
The electrical output of electrofishing equipment is commonly standardized by using either constant voltage or constant amperage, However, simplified circuit and wave theories of electricity suggest that standardization of power (wattage) available for transfer from water to fish may be critical for effective standardization of electrofishing. Electrofishing with standardized power...

Presence, distribution, and potential sources of nitrate and selected pesticides in the surficial aquifer along the Straight River in north-central Minnesota, 1992-93 Presence, distribution, and potential sources of nitrate and selected pesticides in the surficial aquifer along the Straight River in north-central Minnesota, 1992-93
The presence and distribution of nitrate and selected pesticides in ground water in the surficial aquifer along the Straight River in north-central Minnesota were studied. Local residents and public officials are concerned that these substances may pose a health hazard to humans and livestock. Nitrate and pesticides may move downward from cultivated croplands, livestock feedlots and...

Preface: Bridging the gap between theory and practice on the upper Mississippi River Preface: Bridging the gap between theory and practice on the upper Mississippi River
In July 1994, the Upper Mississippi River (UMR) served as a nexus for coalescing scientific information and management issues related to worldwide floodplain river ecosystems. The objective of the conference ‘Sustaining the Ecological Integrity of Large Floodplain Rivers: Application of Ecological Knowledge to River Management’, was to provide presentations of current ideas from the...

Contributing areas of water-supply wells in Elkton and Pigeon, Huron County, Michigan Contributing areas of water-supply wells in Elkton and Pigeon, Huron County, Michigan
The villages of Elkton and Pigeon in Huron County, Michigan, depend on wells completed in the Marshall aquifer to provide a reliable source of potable water. In order to protect the quality of water pumped from these wells, these municipalities need to ensure that potentially harmful contaminants do not enter the Marshall aquifer within the contributing areas of these wells. The Well...

Bioassessment of contaminant transport and distribution in aquatic ecosystems by chemical analysis of burrowing mayflies (Hexagenia) Bioassessment of contaminant transport and distribution in aquatic ecosystems by chemical analysis of burrowing mayflies (Hexagenia)
Burrowing mayfly nymphs (Ephemeroptera) inhabit and ingest fine-grained sediments and detritus that may be enriched with metals and persistent organic compounds. The burrowing nymphs can externally adsorb and internally assimilate these contaminants, providing a link for the food chain transfer of potentially toxic substances from sediments to organisms in higher trophic levels. The...

The occurrence of mycoplasmas in selected wild North American waterfowl The occurrence of mycoplasmas in selected wild North American waterfowl
We determined the prevalence of mycoplasma infection in breeding mallard (Anas platyrhynchos) and canvasback (Aythya valisineria) hens and their broods from the central United States (1988 to 1990); and wintering American black duck (Anas rubripes) and mallard hens from the eastern United States (1990 to 1993). Mycoplasmas were isolated by culturing tracheal swabs from 656 live birds and...
