In this study, we conducted an epidemiological investigation and analyzed the agreement between the Faust technique and the immunochromatographic assay in the diagnosis of Giardia spp. in 272 cats in the municipality of Londrina, Paraná state, Brazil. We identified an overall prevalence of 74.63% (203/272 [95% CI: 69.14–79.44%]) of Giardia spp. in cats, being significantly higher in adult and non-domiciled animals, which prese...

Recent fissure-fed eruptions from the Svartsengi Volcanic System have significantly impacted Iceland’s Reykjanes Peninsula. With eruptions likely to continue intermittently for decades to centuries, exploring the controls on the locations of fissure-fed eruptions is important for hazard assessment and risk mitigation. This study maps eruptive fissures from six eruptions from December 2023 to September 2024 using satellite and...

Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a widespread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e., par...
