Phylogenetic distance matrix

Phylogenetic distance matrix, used in comparison with the average manhattan chemical distances between the Nasonia species based on the relative differences between their normalized CHC peak areas, performed separately for males and females (Fig. 2 and 3, respectively). The molecular distances are based on the Nasonia phylogeny, which are themselves based on the genetic divergence of a mitochondrial gene, COI sequences retrieved from NCBI, pairwise p-distances calculated with MEGA 3.0 (Werren et al., 2010) For further information, please see Materials and Methods section in the paper as well as the Tables S2 and S3, which give the average manhattan distances the phylogenetic distances were compared to.

本数据集为系统发育距离矩阵（phylogenetic distance matrix），用于基于纳森小蜂属（Nasonia）各物种归一化表皮碳氢化合物（CHC）峰面积的相对差异，计算该属物种间的平均曼哈顿化学距离并开展比较，该分析分别针对雄性与雌性进行（对应图2与图3）。该分子距离基于纳森小蜂属的系统发育关系，而该系统发育关系本身则依托于某一线粒体基因的遗传分化：从NCBI数据库调取的细胞色素C氧化酶亚基I（COI）序列，通过MEGA 3.0计算得到成对p距离（Werren等，2010）。如需获取更多详细信息，请参阅论文的材料与方法部分，以及表S2与表S3，其中列出了用于与系统发育距离进行对比的平均曼哈顿化学距离。
