Article Abstract
Recent observations indicate that climate change over the high latitudes of the Southern Hemisphere is dominated by a strengthening of the circumpolar westerly flow that extends from the surface to the stratosphere. Here we demonstrate that the seasonality, structure, and amplitude of the observed climate trends are simulated in a state-of-the-art atmospheric model run with high vertical resolution that is forced solely by prescribed stratospheric ozone depletion. The results provide evidence that anthropogenic emissions of ozonedepleting gases have had a distinct impact on climate not only at stratospheric levels but at Earth's surface as well.
The global prevalence of coccidia infection in lagomorphs and potential risk factors were investigated through a meta-analysis of 149 studies published between 1951 and 2024. The pooled prevalence of Eimeriidae, Sarcocystidae and Cryptosporidiidae was found to be 66.0 %, 8.
This paper investigates the evolution of changes in surface ultraviolet (UV) radiation globally, emphasizing the significant impacts of key factors influencing its variability, i.e., total column ozone, aerosols, clouds, and surface reflectivity.

Objectives: This study aimed to evaluate the potential reduction in distance and travel time with a hypothetical municipal distribution of specialized component medicines in the state of Paraná.
Methods: This was a cross-sectional study. Distances and travel times from all the 1025 residential locations in the state of Paraná to dispensing pharmacies were calculated in 2 different models: centralized model with drugs dispensed in the 22 state-owned pharmacies and decentralized model with drugs dispensed in the 399 municipal pharmacies.

Plastic pollution has garnered much more attention in marine environments, while scientific research on freshwater and terrestrial ecosystems has been relatively overlooked. Numerous studies worldwide have highlighted the presence of macroplastics (>2.5 cm) in mountain riverine environments, revealing that even these seemingly pristine ecosystems are not invulnerable to plastic contamination.
