Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Filtration Capacity and Behaviour of Juvenile Green-Lipped Mussels in Small-Volume Bioassays

open access: yesOmni-Akuatika
This research specifically observes the duration of valve opening and closure in three different size classes of juvenile mussels (Perna canaliculus) over a 60-minute period after exposure to the microalgae Isochrysis galbana. Current study would like to

300 Years of Degradation in Wales Estuaries and Coasts

open access: yesNatural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Sex‐Specific Involvement of Gut Microbiota in Behavioral and Endocrine Responses to Chronic Predator Odor in Brandt's Voles

open access: yesIntegrative Zoology, EarlyView.
18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐

Notes on the Mollusca from Site 41DT59, Cooper Lake, Delta County, Texas [PDF]

open access: yes, 2000
This paper focuses on the information about the mollusca from site 41DT59. The author takes the information from Dr. Fullington, the noted malacologist, and illustrates how the archeologist can take the information and apply it to site analysis.
