Using Trail Cameras to Monitor Culvert Connectivity in Wadeable Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Anthropogenic barriers in aquatic habitats have led to fragmentation and decreased fish diversity worldwide. Road crossing barriers such as culverts are a significant source of fragmentation and can impede aquatic organism passage (AOP). Many large extent efforts to inventory road crossing barriers and prioritize restoration efforts do not ...

Predicting Wave‐Induced Sediment Resuspension at the Perimeter of Lakes Using a Steady‐State Spectral Wave Model

open access: yesWater Resources Research, 2019
A steady‐state spectral wave model, STWAVE, is evaluated as a tool for predicting wave‐induced sediment resuspension in lake littoral zones. Steady‐state wave height and bed‐shear stress estimates are tested against 2 years of high‐frequency wave height ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Estado trófico e bioacumulação do fósforo total no cultivo de peixes em tanques-rede na área aquícola do reservatório de Itaipu = Trophic level and bioaccumulation of total phosphorus in cage fish rearing in the aquaculture area at Itaipu reservoir

open access: yesActa Scientiarum: Biological Sciences, 2008
A intensa produção de peixes e utilização dos recursos hídricos podecomprometer a qualidade e disponibilidade da água, além de afetar a capacidade de suporte do ambiente, causando eutrofização e, consequentemente, a poluição do mesmo.

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...
