Competitive interactions between walleye (Sander vitreus) and smallmouth bass (Micropterus dolomieu) under various controlled conditions
The range of smallmouth bass (Micropterus dolomieu) is expanding northward, creating new interactions with native predators, including walleye (Sander vitreus). We used a series of experiments toExpand

Influence of Fluctuating Water Levels on Mercury Concentrations in Adult Walleye
Atmospheric deposition of mercury (Hg) has been shown to be a significant source of Hg on the landscape (Rada et al. 1989; Swain et al. 1992) and is believed to contribute to increased HgExpand

Fate of geothermal mercury from Yellowstone National Park in the Madison and Missouri Rivers, USA.
Mercury is a worldwide contaminant derived from natural and anthropogenic sources. River systems play a key role in the transport and fate of Hg because they drain widespread areas affected by aerialExpand

Influence of Season, Sex, Age and Diet Composition on Mercury Concentration in Walleye Sander vitreus
We collected Walleye Sander vitreus (May–October) from Bitter and Twin lakes, South Dakota to assess seasonal- and diet-related variation in tissue mercury (Hg) concentration. The average HgExpand

The cost of capturing prey: measuring largemouth bass (Micropterus salmoides) foraging activity using glycolytic enzymes (lactate dehydrogenase)
We used muscle-derived lactate dehydrogenase (LDH) to measure effects of prey size and vegetation density on anaerobic foraging activity by largemouth bass (Micropterus salmoides). Largemouth bassExpand

Vulnerability of age-0 pallid sturgeon Scaphirhynchus albus to fish predation
Summary Stocking is a commonly employed conservation strategy for endangered species such as the pallid sturgeon, Scaphirhynchus albus. However, decisions about when, where and at what size pallidExpand

Preliminary Investigations into the Toxicity of Game Fish in the Clark Fork River downstream from the Smurfit Stone Container Mill
The pulp and paper mill industry is one of the largest polluters of freshwater ecosystems (reviewed in McMaster et al 1991, Servos et al 1996). In particular, the compounds that are formed in theExpand
The Cost of Capturing Prey: Measruing Largemouth Bass Foraging Activity Using Glycolytic Enzymes (Lactate Dehydrogenase)
THE COST OF CAPTURING PREY: MEASURING LARGEMOUTH BASS FORAGING ACTIVITY USING GLYCOLYTIC ENZYMES (LACTATE DEHYDROGENASE) Trevor M. Selch 21 July 2004 Optimal foraging theory predicts that predatorsExpand

Application of multistate modeling to estimate salmonid survival and movement in relation to spatial and temporal variation in metal exposure in a mining-impacted river
Multistate modeling was used to estimate survival and movement of brown trout (Salmo trutta) and westslope cutthroat trout (Oncorhynchus clarkii lewisi) in relation to copper concentrations in the ...
