Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...

Scorpionism has emerged as a growing public health concern in Brazil, characterized by increasing incidence and geographic expansion. Despite this trend, studies integrating climatic drivers and advanced time-series modeling remain limited. This study aims to analyze the temporal dynamics, spatial diffusion, and climate–disease relationships of scorpion sting incidence in Brazil using a nationwide dataset from 2007 to 2025. Mo...

This study identified four hidden rainfall states in Northeast Brazil (NEB) during the austral autumn (March–May) from 1981 to 2015 using a Hidden Markov Model (HMM). Two states correspond to widespread dry (State 1) and wet (State 2) conditions, both exhibiting strong daily persistence and associations with large‐scale atmospheric features, including the Intertropical Convergence Zone (ITCZ), the South American Monsoon System...

Our objective was to evaluate the impacts of the treatment of banana leaf hay with levels of sodium hydroxide (NaOH) on intake, digestibility, feeding behavior, and blood parameters of sheep. Five ½ Santa Ines × Dorper sheep with body weight of 38.43 ± 4.38 kg were used in a Latin square design. Treatments were based on levels of NaOH in banana leaf hay, as follows: 0; 1.25; 2.5; 3.75 and 5%. Overall, the intakes of dry matter...

Climate change is causing significant changes in maritime habitats, altering the distribution of marine organisms and potentially leading to poleward migration of species, impacting fishing operations and coastal communities' subsistence methods. The present study analyzed the distribution of the Indian Ocean immature albacore tuna ( Thunnus alalunga ) by using an ensemble modeling approach and considering three representative...
