PFAS from a Discrete‐Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages

Groundwater, EarlyView.
PFAS is conveyed to the coastal intertidal zone from sources across the terrestrial landscape. Discharge of PFAS into the coastal ecosystem is complicated in space and time by the ongoing bi‐directional exchange of terrestrial groundwater and ocean water driven by tidal pumping within discharge areas.

When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

Groundwater, EarlyView.
Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

Insect Conservation and Diversity, EarlyView.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide

High‐Concentration Hydrogen Peroxide Gels Containing Calcium Polyphosphate Associated With Violet Led Light: Bleaching Efficacy and Effects on Enamel Properties

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effect of violet LED light (VL) and hydrogen peroxide (HP) in‐office bleaching gels supplemented with calcium polyphosphate (CaPP) or calcium gluconate (GU): Materials and Methods Bovine enamel blocks (n = 10) were randomly assigned: commercial HP gel, commercial HP gel with GU, or experimental 35% HP with or without

Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

Journal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

Journal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

Journal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Return migration to fresh water and overwintering locations used by sympatric anadromous populations of Arctic char (Salvelinus alpinus) and Dolly Varden (Salvelinus malma malma)

Journal of Fish Biology, EarlyView.
Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...
