Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

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

open access: yesJournal 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 ...

Too hot for comfort: Elevated temperatures influence gene expression and exceed thermal tolerance of bigmouth shiners, Ericymba dorsalis

open access: yesJournal of Fish Biology, EarlyView.
Abstract Environmental and associated ecosystem change may affect the persistence of fish species based on their ability to adapt to changing conditions, including decreasing flows and rising water temperatures. Exceeding the thermal tolerances of stream fish will likely result in a loss of ability to maintain metabolic processes.

Complex demographic, developmental, fitness, and physiological responses of larval eastern hellbenders to elevated water conductivity

open access: yesJournal of Zoology, EarlyView.
Here we explore the effects of elevated water conductivity on larval eastern hellbenders (Cryptobranchus a. alleganiensis), both lethal and sublethal. We found that elevated water conductivity significantly impacts both survival and morphology, though it has limited effects on locomotor performance, stress physiology, and oxidative stress.

Root water uptake depth in temperate forest trees: species‐specific patterns shaped by neighbourhood and environment

open access: yesPlant Biology, EarlyView.
Root water uptake strategies vary among temperate tree species (European beech, Douglas fir, and Norway spruce), with beech–conifer mixtures altering water uptake depths, while site conditions and temporal dynamics further shape the contribution of different soil depths to water supply.
