Journal of Applied Toxicology, EarlyView.ABSTRACT 6PPD‐quinone (6PPD‐Q), a transformation product of the tire antioxidant 6PPD, causes acute mortality in several salmonid species, but its toxicity varies markedly among fish species. Disruption of vascular‐barrier integrity and inflammatory signaling has been proposed as a key mechanism of 6PPD‐Q toxicity.

A framework for investigating fish population density responses to habitat fragmentation
Oikos, EarlyView.Globally, fish populations that rely on rivers are being fragmented by in‐stream barriers, but it is unclear how pervasive any negative population responses to fragmentation are. We developed a modeling framework for estimating density responses of fishes upstream and downstream of in‐stream barriers and applied it to learn how low‐head dams have ...

People and Nature, EarlyView.Abstract Wild deer populations are increasing across the northern hemisphere, posing challenges to the environment and people. Deer impacts can be managed using lethal and non‐lethal practices, but research suggests lethal control receives mixed support.

Effect of salinity on motility and viability of salmonid spermatozoa [PDF]
Acta Ichthyologica et Piscatoria, 1979 Spermatozoa of trout (Salmo trutta L.), lake trout (S. trutta m. lacustris L.), rainbow trout (S. gairdneri Rich.), and brook trout (Salvelinus fontinalis (Mitch.)) kept at 8-10°C without water in various diluting fluids behaved in all media more

Perceptions of nativeness shift quite rapidly over time
People and Nature, EarlyView.Abstract The spread of non‐native species has emerged as one of the most pressing challenges for conservation and ecosystem management. Yet attitudes towards species change, making it possible for non‐native species to be perceived as native after some time.

The Japanese Journal of Genetics, 1988 Silver-banded karyotypes of the rainbow trout Salmo gairdneri, the brook trout Salvelinus fontinalis, and their hybrids were described. Diploid-type and triploid-type hybrids were obtained. Triploid-type hybrids had two maternal genomes of the rainbow trout and one paternal genome of the brook trout.

River Research and Applications, EarlyView.ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Declines in Brook Trout Abundance Linked to Atmospheric Warming in Maryland, USA
HydrobiologySalmonid fishes provide an important indicator of climate change given their reliance on cold water. We evaluated temporal changes in the density of stream-dwelling brook trout (Salvelinus fontinalis) from surveys conducted over a 36-year period (1988 ...

River Research and Applications, EarlyView.ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.
