摘要 蚂蚁是最严重的入侵物种之一，会对本地生物多样性、农业、房地产、财产和人类健康产生巨大的负面影响。入侵的蚂蚁极难控制，因此早期发现对于防止蚂蚁入侵至关重要，特别是通过在入境口岸进行监测。本文评估了法国 14 种最严重入侵蚂蚁物种在当前和未来气候条件下的潜在分布。使用五种不同的建模技术、三种全球气候模型和两种二氧化碳排放情景的共识物种分布模型表明，法国为 10/14 种物种提供了适宜的区域，其中包括入侵物种专家组评选的世界 100 种最严重入侵物种中的 5 种。在这 10 个物种中，有 8 个物种预计会随着气候变化而扩大其潜在范围。潜在入侵者最集中的地区主要位于海岸线沿线，特别是法国西南部，但所有部门的气候似乎都适合至少两种入侵物种。对17个主要机场和14个海港的物种气候适宜性排名显示，适宜性最高的入境口岸位于比亚里茨、土伦和尼斯，在法国最有可能分布的物种是Lasiusignoreus和Linepithemahumile，其次是Solenopsisrichteri、Pheidolemegacephala和Wasmanniaauropunctata。
SUMMARY Ants are among the worst invasive species, and can have tremendous negative impacts on native biodiversity, agriculture, estates, property and human health. Invasive ants are extremely difficult to control, and thus early detection is essential to prevent ant invasions, in particular through surveillance efforts at ports of entry. This paper assesses the potential distribution of 14 of the worst invasive ant species in France, under current and future climatic conditions. Consensus species distribution models, using five different modelling techniques, three global climate models and two CO2 emission scenarios, indicated that France presented suitable areas for 10/14 species, including five listed on the Invasive Species Specialist Group's selection of the world's 100 worst invasive species. Among these 10 species, eight were predicted to increase their potential range with climate change. Areas with the highest concentration of potential invaders were mainly located along the coastline, especially in the south-west of France, but all departments appeared to be climatically suitable for at least two invasive species. A ranking of climatic suitability per species for 17 major airports and 14 maritime ports indicated that the ports of entry with the highest suitability were located in Biarritz, Toulon and Nice, and the species with the greatest potential distribution in France were Lasius neglectus and Linepithema humile, followed by Solenopsis richteri, Pheidole megacephala and Wasmannia auropunctata.
