Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River Open
Hydrologic connectivity, the network of water pathways linking aquatic habitats, is vital for the exchange of organisms and abiotic materials between rivers and adjacent waterbodies. This study quantified hydrologic connectivity for 1,283 …

Assessment of pollution and other impairments of US reservoirs based on expert opinion Open
A comprehensive understanding of the prevailing pollution and other impairments to reservoirs is necessary at the national level to analyze patterns and causes as well as allocate national resources effectively. Most of these impairments a…

Population characteristics of silver carp from the source of their North American introduction in the Lower Mississippi River Open
Silver carp, Hypophthalmichthys molitrix , escaped into the Lower Mississippi River (LMR) over 50 years ago, established reproductive populations, and spread across much of the Mississippi River Basin. Demographic rates of silver carp are …

Fish life-history traits predict abundance-occupancy patterns in artificial lakes Open
Life-history traits of a species have been postulated as a factor in abundance and occupancy patterns. Understanding how traits contribute to the ubiquity and rarity of taxa can facilitate the development of effective conservation policy b…

Aging, Climate, and Invasions Threaten Reservoirs in the Mississippi River Basin Open
Reservoirs in the Mississippi River basin are facing three momentous threats. The first two, aging and climate change, are relatively slow moving and their signal can be hard to discern given their stretched temporal scales. The third, spe…

Influence of invasive bigheaded carps on abundance of Gizzard Shad in the Tennessee River Open
Objective The Tennessee River basin and its cascade of reservoirs are home to some of the most diverse freshwater fish assemblages in the world. This unique system is threatened by the ongoing invasion of Silver Carp Hypophthalmichthys mol…

Impact of Dams on Stream Fish Diversity: A Different Result Open
Impoundments can drastically change the physical and biological characteristics of fluvial systems. Changes in the physical characteristics, such as reductions in flow, increased sediment deposition, and increased surface area, often influ…

Fish functional gradients along a reservoir cascade Open
The transformations of fish assemblages caused by reservoir cascades can be severe at the reach scale, but basin‐scale effects are less clear. However, prevailing river concepts provide a framework for predicting basin‐scale effects. To de…

Patterns of zero and nonzero counts indicate spatiotemporal distributions, aggregation, and dispersion of invasive carp Open
Bigheaded carp Hypophthalmichthys spp.are invasive species native to Asia expanding in the Mississippi River Basin in North America.An understanding of spatiotemporal distribution and aggregation of invasive carp is key to establishing whe…

Retention and Dimensional Changes of Evergreen Brush Piles Within a Flood Control Reservoir Open
Brush piles (i.e., trees and large woody debris) are often installed in reservoirs to supplement fish habitat. The retention and dimensional change of brush piles after installation is important information that can be used to maximize the…

Selection of Habitat-Enhancing Plants Depends on Predator–Prey Interactions Open
Shallow areas of drawdown reservoirs are often devoid of adequate fish habitat due to degradation associated with unnatural and relatively invariable cycles of exposure and flooding. One method of enhancing fish habitat in these areas is t…

Bidirectional connectivity via fish ladders in a large Neotropical river: Response to a comment Open
In a recent article, we described fitting electronic tags to the fish Prochilodus lineatus to document how a fishway connected aquatic habitats downstream and upstream of a major dam. Moreover, given that tagged fish remained upstream or d…

Reservoir Fish Habitats: A Perspective on Coping with Climate Change Open
Climate change is the defining environmental problem for our generation. The effects of climate change are increasingly evident and are anticipated to profoundly affect our ability to conserve fish habitats and fish assemblages. Reservoirs…

Longitudinal distribution of uncommon fishes in a species‐rich basin Open
The spatial organization of fishes in a river system was investigated to evaluate the longitudinal distribution of uncommon species. It was anticipated that overall richness of the fish community would increase in a downstream direction to…

Using long-term data to predict fish abundance: the case of Prochilodus lineatus (Characiformes, Prochilodontidae) in the intensely regulated upper Paraná River Open
Populations show spatial-temporal fluctuations in abundance, partly due to random processes and partly due to self-regulatory processes. We evaluated the effects of various external factors on the population numerical abundance of curimba …
