Fishing gear performance nearshore is substantiated by spatial analyses
We estimated whether the fish assemblages nearshore represented by electrofishing and gillnetting indexed location of reservoirs in a river basin. We expected that location in the basin would reflect a multipl...

An inventory and typology of permanent floodplain lakes in the Mississippi Alluvial Valley: a first step to conservation planning
The alluvial valley of the Mississippi River is an extensive area harboring hundreds of lakes created by fluvial dynamics. These floodplain lakes are scattered throughout the valley and carved over thousands o...

Wetlands and development influence fish diversity in a species-rich small river
We identified in-stream and off-stream characteristics that influenced various species diversity metrics in reaches of the Duck River Basin, Tennessee, USA. This relatively small basin is home to one of the mo...

Gradients in fish feeding guilds along a reservoir cascade
The river continuum concept predicts a longitudinal gradient in the structure and functioning of rivers. Impoundments potentially change this continuum by reorganizing nutrient transport and storage in the sys...

Role of riparian shade on the fish assemblage of a reservoir littoral
Research into the effects of shade on reservoir fish assemblages is lacking, with most investigations focused on streams. Unlike many streams, the canopy in a reservoir shades only a narrow fringe of water adj...

A classification system for large reservoirs of the contiguous United States
Degradation of reservoir fish habitat has become a serious concern. Habitat issues—such as sedimentation, excessive nutrient loadings, and lack of submerged structure—may emerge and worsen over time and are ac...

The role of depth in regulating water quality and fish assemblages in oxbow lakes
We evaluated water quality and fish assemblages in deep (>3.0 m; N = 7) and shallow (<1.5 m; N = 6) floodplain lakes in the intensively cultivated Yazoo River Basin (Mississippi, USA) using indirect gradient mult...

Floodplains within reservoirs promote earlier spawning of white crappies Pomoxis annularis
Reservoirs impounded over floodplain rivers are unique because they may include within their upper reaches extensive shallow water stored over preexistent floodplains. Because of their relatively flat topograp...

Monitoring fish distributions along electrofishing segments
Electrofishing is widely used to monitor fish species composition and relative abundance in streams and lakes. According to standard protocols, multiple segments are selected in a body of water to monitor popu...

Effects of Smallmouth Buffalo, Ictiobus bubalus Biomass on Water Transparency, Nutrients, and Productivity in Shallow Experimental Ponds
The smallmouth buffalo Ictiobus bubalus is a native benthivore to floodplain lakes in the Yazoo River Basin, USA. Based on evidence from other benthivorous fish studies we hypothesized high biomasses of I. bubalu...

Environmental variables measured at multiple spatial scales exert uneven influence on fish assemblages of floodplain lakes
We examined the interaction between environmental variables measured at three different scales (i.e., landscape, lake, and in-lake) and fish assemblage descriptors across a range of over 50 floodplain lakes in...

Connectedness of land use, nutrients, primary production, and fish assemblages in oxbow lakes
We explored the strength of connectedness among hierarchical system components associated with oxbow lakes in the alluvial valley of the Lower Mississippi River. Specifically, we examined the degree of canonic...

Fish assemblage dynamics in a Neotropical floodplain relative to aquatic macrophytes and the homogenizing effect of a flood pulse
The presence of aquatic macrophytes is a key factor in the selection of habitats by fish in floodplain lakes because these plants enhance the physical and biological complexities of aquatic habitats. The seaso...

Hierarchy in factors affecting fish biodiversity in floodplain lakes of the Mississippi Alluvial Valley
River-floodplain ecosystems offer some of the most diverse and dynamic environments in the world. Accordingly, floodplain habitats harbor diverse fish assemblages. Fish biodiversity in floodplain lakes may be ...

Depth as an organizer of fish assemblages in floodplain lakes
Depth reduction is a natural process in floodplain lakes, but in many basins has been accelerated by anthropogenic disturbances. A diverse set of 42 floodplain lakes in the Yazoo River Basin (Mississippi, USA)...

Predicting and managing risk of unsuitable dissolved oxygen in a eutrophic lake
Eutrophication of lakes is often accompanied by wide diel fluctuations in dissolved oxygen (DO) concentrations that can influence fish assemblage composition and periodically result in highly visible fish kill...

Hydrologic and climatic regimes limit phytoplankton biomass in reservoirs of the Upper Paraná River Basin, Brazil
In reservoirs of the Upper Paraná River Basin, Brazil Paraguay, phytoplankton biomass is generally low relative to reservoirs in other parts of the world. To investigate what might be limiting phytoplankton bi...

Role of aquatic vegetation coverage on hypoxia and sunfish abundance in bays of a eutrophic reservoir
We studied the relation between aquatic vegetation coverage, summer dissolved oxygen and density of sunfishes (Lepomis spp.) in 10 shallow bays of a eutrophic reservoir. The bays ranged 5.2–15.7 ha in area, 0.6–1...

Dietary shifts of a dominant reservoir planktivore during early life stages
We studied dietary shifts in the early life stages of gizzard shad Dorosoma cepedianum, a dominant forage species in North American reservoirs. Larval fish and zooplankton samples were collected weekly during ...
