Environmentally Realistic Metal Mixture Concentration Impacts Early Development in Zebrafish Larvae

Environmental Toxicology, EarlyView.
ABSTRACT The dispersion of metals in the environment leads to the presence of metal mixtures in impacted ecosystems, but few studies have addressed their impact on early developmental processes in fish. Here, we investigated the effect of metal mixtures reported in the Doce River basin in Brazil, including Fe, Mn, and Cd, either singly or as a mixture ...

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

Environmental 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 ...

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Effects of Simulated Dusk and Dawn on Activity and Feeding of Puerto Rican Crested Toads (Peltophryne lemur) in Captivity

Zoo Biology, EarlyView.
Puerto Rican crested toads (Peltophryne lemur) that were provided with dim night lights to simulate a natural dusk and dawn moved more frequently than those kept in complete darkness at night. Toads moved more at dusk and dawn than in the middle of the night. ABSTRACT Night light may affect captive amphibians in alternative ways. Captive amphibians may
