西方蜜蜂（Apis mellifera）在自然生态系统和人工生态系统中都是极具影响力的传粉者。在北美，这个物种已经从欧洲和非洲的各种不同的来源种群中被引入了很多次。从那时起，野生种群在它们广泛的引进范围内扩展到许多不同的环境。本研究利用历史博物馆标本和美国加利福尼亚州新采集的现代种群的全基因组测序，分析了过去105年来人口统计学和选择对引进种群的影响。我们发现加州北部和南部的人口都表现出明显的基因变化，但变化的方式不同。在北方种群中，自20世纪60年代以来，蜜蜂经历了从西欧到东欧血统的重大转变，而在过去的20年里，南方种群被非洲化基因组的渗入所主导。此外，我们确定了一个孤岛人口，在很长的时间跨度内经历了相对较小的变化。对不同种群和时间点的精细比较也揭示了snp在频率上的差异，突出了一些可能对这些引入种群的近期适应很重要的基因。
The western honey bee, Apis mellifera, is an enormously influential pollinator in both natural and managed ecosystems. In North America, this species has been introduced numerous times from a variety of different source populations in Europe and Africa. Since then, feral populations have expanded into many different environments across their broad introduced range. Here, we used whole genome sequencing of historical museum specimens and newly collected modern populations from California (USA) to analyze the impact of demography and selection on introduced populations during the past 105 years. We find that populations from both northern and southern California exhibit pronounced genetic changes, but have changed in different ways. In northern populations, honey bees underwent a substantial shift from western European to eastern European ancestry since the 1960s, whereas southern populations are dominated by the introgression of Africanized genomes during the past two decades. Additionally, we identify an isolated island population that has experienced comparatively little change over a large time span. Fine-scale comparison of different populations and time points also revealed SNPs that differ in frequency, highlighting a number of genes that may be important for recent adaptations in these introduced populations.
