概括

估计蜜蜂的侵入是复杂的. 这项研究比较了遗传方法,发现单个蜜蜂采样可以低估殖民地层面的内进,特别是当使用某些统计模型时.

科学领域:

人口遗传学人口遗传学
进化生物学进化生物学
养蜂养蜂养蜂养蜂养蜂养蜂养蜂养蜂

背景情况:

人类活动导致蜜蜂 (Apis mellifera) 亚种在本土范围之外引入.
欧洲黑色蜜蜂 (Apis mellifera mellifera) 受到C系蜜蜂的侵入,影响了适应潜力和长期生存能力.
准确估计像蜜蜂这样的哈普罗迪普洛伊德,殖民地生活的昆虫的内入行为,带来了重大挑战.

研究的目的:

为了比较不同的遗传和统计方法的准确性来估计蜜蜂的内进.
评估抽样策略 (个体与聚合) 对内进估计的影响.
确定可靠的方法来评估蜜蜂亚种的侵入性.

主要方法:

三种遗传方法的比较:SNP阵列,个别RAD-seq和聚合殖民地RAD-seq.
评估了两个统计方法:ADMIXTURE (最大概率聚类) 和ABBA BABA (不完整的血统分类模型).
分析从个别工人,个别无人机和聚合殖民地样本中得出的内进估计值.

主要成果:

在使用ADMIXTURE程序时,个人采样方法通常产生较低的内向估计,而不是聚合的殖民地样本.
与所有基于ADMIXTURE的估计相比,聚合殖民地ABBABABA方法产生了较低的内向估计.
结果表明,单个个体可能不足以代表殖民地层面的侵入.

结论:

估计蜜蜂的内进需要仔细考虑遗传和统计方法.
集群群体采样可以提供与单个采样不同的内向估计,需要方法验证.
未来使用聚合殖民地数据的研究不应该仅仅依赖于集群程序,如ADMIXTURE进行内进评估.

Inclusive Fitness

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Understanding Species and Reproductive Barriers

Understanding Species and Reproductive Barriers

A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar and share common characteristics due to their highly similar genomes. However, not all organisms that look alike are members of the same species. Various mechanisms keep most species discrete. While some mechanisms prevent reproductive behavior and fertilization (pre-zygotic isolation), others prevent the production of fertile offspring after mating has...
