Tropical wetlands have historically been resilient to fire, but ongoing climate and hydrological changes are undermining this stability. Here, we provide robust multi‐decadal evidence (1985–2024) of structural changes in the contemporary fire regime of the Pantanal, the world's largest wetland, associated with hydroclimatic disruption. We investigated changes in burned area, mean fire size, and fire seasonality using hydrologi...

Temperature and salinity, derived from over 10 000 Argo profiles, are combined with 20 years of eddy trajectories and absolute dynamic topography maps to characterise the vertical structure of mesoscale eddies within the Azores Current corridor (AzCCo) from the surface to 1500 dbar. From east to west, our statistics reveal an intensification of anomaly maxima (from ∼ 0.5 °C and 0.1 to above ∼ 1.5 °C and 0.2 in salinity) and a...

This study aimed to evaluate the exposure of Chelonia mydas (green turtles) inhabiting the south coast of Pernambuco, Northeast Brazil, to essential and toxic elements. Concentrations of Al, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, and Zn were determined in shell, muscle, liver, and kidney samples from 43 individuals using ICP-OES. Element concentrations varied according to tissue type. Specifically, the average concentrations of A...

Objective To develop an endoscope reprocessing system using ozonated water jets. Methods The system features a jet head with concentric orifices that moves vertically to disinfect the external surface of the endoscope. Simultaneously, ozonated water is injected into the internal channel to ensure complete disinfection. Endoscopes were experimentally contaminated with Staphylococcus aureus and Escherichia coli . Quantitative an...

6-Cyanodopamine (6-CYD) is a recently identified endogenous catecholamine that exerts positive chronotropic and inotropic actions, but its occurrence in vascular tissue and effects on vascular reactivity are unknown. In endothelium-intact and endothelium-denuded rabbit isolated aortic rings, we investigated the basal release of 6-CYD and its effects on aortic smooth muscle reactivity. 6-Cyanodopamine release was quantified by...

Odontogryllus Saussure, 1877 is a ground-dwelling Neotropical group of crickets whose diversity remains underestimated. It is the type genus of Odontogryllini and is currently divided into four subgenera: Odontogryllus ( Sergeigryllus ), Odontogryllus ( Nimiogryllus ), Odontogryllus ( Vladogryllus ), and Odontogryllus ( Odontogryllus ) s.s. The subgenera are mainly differentiated by the position of the tegminal gland opening a...

The consumption of vegetables is essential for human health. However, in regions affected by mining activities, this practice may pose serious risks due to potential heavy metal contamination at the soil–plant interface. This study evaluated the phytotoxicity and metal mobility in lettuce cultivated in mine tailing-contaminated soils after the Córrego do Feijão dam failure (Brumadinho, Minas Gerais, Brazil). The increase in so...

Aim Our goals were (1) to identify the metacommunity structure of the reef fish fauna as well as the structure of its constituent trophic guilds (invertivores, generalist carnivores, omnivores, herbivores, planktivores and piscivores); (2) to evaluate the extent to which metacommunity compartmentalization is associated with biogeographic phenomena (isolation by distance, habitat filtering, estuarine plumes): and (3) to identif...

Atlantic bluefin tuna (ABFT) is an ecologically and economically valuable species. As global warming drives marine species toward cooler or deeper waters, ABFT distributions are expected to shift, potentially disrupting predator–prey dynamics and fisheries interactions. This study models future habitat suitability for ABFT, its primary prey (as a proxy for food availability), and the drifting longline fishery that targets adul...
