岛屿是受到入侵物种负面影响的孤立环境。在夏威夷，迄今为止至少有21种非本地蜜蜂被记录在案，加入了超过9,000种非本地和入侵物种的多样性。本研究的目的是描述的持久性，遗传多样性，和自然历史的最新建立的蜜蜂夏威夷，切叶蜂policochilae说，1831年（Hyattera：切叶蜂科）。当代调查表明，M.至少在夏威夷、毛伊岛和夏威夷岛上都有，最早的发现是在2017年。此外，社区成员的反复调查和观察支持了这一假设，即M。从2017年到2020年，夏威夷岛已经建立了警察局。细胞色素氧化酶I基因座的DNA测序片段在夏威夷岛上鉴定出两种不同的单倍型，表明至少有两个创始人在岛上定居。在其原产地，M.据记载，海百合以至少21种不同的植物科为食，这些植物科在夏威夷有代表性。最后，利用四个生物气候变量和M. policeconomy预测，整个群岛岛屿的背风面和高海拔生境具有很高的生境适宜性。虽然我们研究中的许多观察结果都在夏威夷的预测栖息地适宜性范围内，但我们也检测到了M。policarison的迎风面的夏威夷岛，这表明我们构建的SDM可能没有捕捉到的生物气候生态位的灵活性的物种。
Islands are insular environments that are negatively impacted by invasive species. In Hawai‘i, at least 21 non-native bees have been documented to date, joining the diversity of >9,000 non-native and invasive species to the archipelago. The goal of this study is to describe the persistence, genetic diversity, and natural history of the most recently established bee to Hawai‘i,Megachile policarisSay, 1831 (Hymenoptera: Megachilidae). Contemporary surveys identify thatM. policarisis present on at least O‘ahu, Maui, and Hawai‘i Island, with the earliest detection of the species in 2017. Furthermore, repeated surveys and observations by community members support the hypothesis thatM. policarishas been established on Hawai‘i Island from 2017 to 2020. DNA sequenced fragments of the cytochrome oxidase I locus identify two distinct haplotypes on Hawai‘i Island, suggesting that at least two founders have colonized the island. In their native range,M. policarisis documented to forage on at least 21 different plant families, which are represented in Hawai‘i. Finally, ensemble species distribution models (SDMs) constructed with four bioclimatic variables and occurrence data from the native range ofM. policarispredicts high habitat suitability on the leeward side of islands throughout the archipelago and at high elevation habitats. While many of the observations presented in our study fall within the predicted habitat suitability on Hawai‘i, we also detected theM. policarison the windward side of Hawai‘i Island suggesting that the SDMs we constructed likely do not capture the bioclimatic niche flexibility of the species.
