The research employed next-generation sequencing (NGS) to identify viruses present in pooled mosquito samples collected in July 2022 and July 2023. The findings reveal a diverse and, importantly, a unique virome in these Arctic mosquitoes compared to other Aedes species. The study highlights the critical need to understand these viromes in light of climate change, which is significantly impacting Arctic ecosystems and potentially increasing the risk of vector-borne disease emergence and spread.Key Findings and Themes:Dominance of Aedes impiger: Contrary to previous assumptions that Aedes nigripes was the sole mosquito species in western Greenland, this study found Aedes impiger to be the predominant species collected at the Kangerlussuaq site.Fact: \"Where a definitive identification could be made, A. impiger was the most frequently sampled mosquito at the Kangerlussuaq site.\"Fact: In 2023, \"49 mosquitoes were identified as A. impiger (70%) and 16 as A. nigripes (23%).\"Novel and Diverse Arctic Mosquito Virome: Metagenomic analysis identified a range of RNA viruses belonging to various families in both Aedes impiger and Aedes nigripes. Many of these viruses are novel and exhibit low sequence identity (sometimes as low as 34% at the amino acid level) when compared to previously published virus sequences from other...","thumbnail_url":"https://img.transistorcdn.com/qJYlR2Phxe3IMx6KHnsmKp1D71DIqj8LuYMSrDKo9Jc/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS82MDgx/MDIyNmJkNWU5YmIz/NzJhZDVmZjYyOGZi/NTgxMi53ZWJw.webp","thumbnail_width":300,"thumbnail_height":300}
