进化基因组学分析揭示了百慕大一个孤立种群中 Megachile pruina 的独特品系

蜜蜂多样性的减少主要是由栖息地丧失、气候变化和入侵物种造成的，这一点已得到充分证明。在这一背景下，Megachile Latreille, 1802属（膜翅目：Megachilidae）这一种类繁多的独居食叶蜂缺乏全面的物种保护和分类评估，可能掩盖了种群数量下降和灭绝的事实。Megachile pruina 是百慕大的三种蜜蜂之一，也可能是岛上最后一种本地蜜蜂。它曾广泛分布于全岛各地，现在仅限于城堡港群岛自然保护区内 11.5 公顷的一小块区域。根据《百慕大保护物种法案》（Bermuda Protected Species Act），它被列为 "易危 "物种，其分类学和保护状况仍不确定，尤其是它与美国种群的进化关系。在这里，我们分析了核基因组和线粒体基因组，发现百慕大的M. pruina种群在遗传学上与美国本土种群截然不同，与任何取样的美国种群都没有密切联系，这表明百慕大的M. pruina种群代表了一个独特的进化系。我们的遗传多样性评估显示，与美国相比，百慕大种群的遗传多样性较低，凸显了比最初想象的更高的脆弱性。我们建议维持其目前的保护地位，并主张迫切需要扩大生态和生物研究，以促进适当的保护和监测措施。
