Climatic and Hydrological Changes Drive Contemporary Fire Regime Transitions in the World's Largest WetlandNARA Subscribed
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...
How Wastewater Monitoring is Helping to Investigate a Hepatitis A Outbreak Linked to Oysters’ ConsumptionNARA Subscribed
In April 2024, two cases of hepatitis A (HA) were linked to the consumption of oysters produced in the same region, which triggered a multidisciplinary study. A network was quickly set up in a one-health approach including epidemiological and clinical data, as well as analysis of locally collected shellfish and wastewater samples. By the end of the outbreak, up to 17 HA cases met the case definition: all shared a same genotype...
Dry–Hot Compound Events Driving the 2024 Pantanal WildfiresNARA Subscribed
The year 2024 was classified by the World Meteorological Organization (WMO) as the hottest on record, both globally and in Brazil. In the Pantanal, exceptional heat waves and intense droughts led to an early onset of the fire season in June, marked by high fire severity and large burned areas. Although the Pantanal has been increasingly affected by combined drought and heat events, the influence of these climatic extremes on f...
Metabolic syndrome (MS) represents a major global health problem affecting a large proportion of the population. The improper management of peripheral carbohydrates and lipids leads to behavioral changes in neurons of the limbic brain. This work studied male rats that received diets high in carbohydrates, lipids, and their combination for ninety days. The study examined how peripheral metabolic changes and hypothalamic-pituita...
Monitoring stress in captive fish is crucial for their welfare, but continuous physiological measures in unrestrained animals are challenging. Rainbow trout (Oncorhynchus mykiss) exhibit divergent personalities, ranging from bold to shy, which correlate with cortisol-mediated stress responses. To determine whether personality affects the sympathetic nervous system, heart rate was measured during three potentially stressful eve...
The objective of the present study was to investigate the optimal dietary protein requirement and the effect of varying protein levels on the growth and health of juvenile, wild‐caught Atlantic wolffish, Anarhichas lupus , a promising candidate for cold‐water aquaculture diversification. Six iso‐energetic (ca. 18.3 MJ kg −1 ), fish meal‐based experimental diets were formulated with crude protein levels ranging from 35% to 60%,...
