冰岛首次发现蚊子！

Core Viewpoint - The discovery of mosquitoes in Iceland challenges the long-held belief that it was the only country without mosquitoes, highlighting the impact of climate change on species distribution [2][3]. Group 1: Discovery and Significance - The Icelandic Institute of Natural History confirmed the first presence of mosquitoes in the country, specifically identifying them as "Culex pipiens" [2][3]. - This finding is significant as it marks the first time mosquitoes have been confirmed to be active outdoors in Iceland, despite occasional sightings on flights to the country [3]. Group 2: Potential Origins and Environmental Implications - The mosquitoes are believed to have arrived from a nearby industrial area approximately 6 kilometers away, where goods are transported internationally [3]. - Scientists had previously predicted that environmental changes could allow mosquitoes to establish stable populations in Iceland, indicating a broader trend of species moving to higher latitudes due to climate change [3]. Group 3: The Mystery of Iceland's Previous Mosquito-Free Status - Prior to this discovery, Iceland was one of the few regions with suitable living conditions for humans that did not have a mosquito population, leading to the "mosquito mystery" [3]. - Reports indicated that Iceland's climate is not extremely cold and has ample water bodies for mosquito breeding, adding complexity to the understanding of its previous lack of mosquitoes [3].
