Metabolic and cometabolic degradation of herbicides in the fine material of railway ballast [PDF]

, 2006
Microbial degradation of 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) and mineralization of 4-chloro-2-methylphenoxyacetic acid (MCPA) were studied in soil samples taken from the ballast layers of three Swedish railway embankments. The degradation of

Potential Impacts of Climate Interventions on Marine Ecosystems

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

Stress related epigenetic changes may explain opportunistic success in biological invasions in Antipode mussels [PDF]

, 2018
Different environmental factors could induce epigenetic changes, which are likely involved in the biological invasion process. Some of these factors are driven by humans as, for example, the pollution and deliberate or accidental introductions and others

Behaviour of Temperate Reef Fish Species Around Oyster Aquaculture Farms and Natural Rock Reefs

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Cultivation of eastern oysters using aquaculture gear increases habitat for temperate reef fish. Cunner (Tautogolabrus adspersus), scup (Stenotomus chrysops) and tautog (Tautoga onitis) inhabit a variety of complex natural and manmade habitats, including oyster aquaculture cage farms.

Evaluating the Risk of Collision of Seals Swimming Within Metres of Operating Tidal Turbines

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT We used imaging sonar to continuously monitor wildlife at an operational tidal turbine in the Pentland Firth, Scotland, between May 2022 and June 2023. Of 704 detected seal tracks, 347 occurred during turbine operation and 122 of these were detected directly upstream of the rotating blades in the horizontal plane.

Anomalously Low New Production in the Northeast Atlantic During Spring 2024: A Consequence of Weaker Winter Mixing?

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract In 2024 an anomalous region of low chlorophyll water covering ∼721,000 km2 or 1.7% of North Atlantic surface area dominated the Northeast Atlantic. This feature formed during spring, remained identifiable as a region of low chlorophyll throughout the summer months in temperate and subpolar waters and, due to low opal ballasting potential of ...
