HopkinsLandmarksJEB

The text file "HopkinsLandmarksJEB.txt" contains x and y coordinates landmarks for all specimens used in this analysis before paired landmarks were reflected across the sagittal axis. The first column shows the species name. The second column shows the collection number that the specimen came from or the museum repository number for the specimen (all specimens prefaced with “USNM” are held at the National Museum of Natural History, Smithsonian). See Hopkins 2011 (Evolution 65:3252-3273, Tables S1, S2) for locality information for each collection. The remaining columns list the x and y coordinates of each landmark from 1 to 15. See figure in ReadMe file for landmark chart (compare with Figure 1 in which landmarks are numbered after reflection). Missing landmarks are indicated by "NA". The baseline for reflection was defined by landmarks 2 and 4. Some of these data were previously made available on Dryad because they were used in the Evolution paper cited above.文本文件"HopkinsLandmarksJEB.txt"收录了本次分析所用全部标本的地标点x、y坐标数据，该数据为成对地标点沿矢状轴镜像翻转前的原始坐标。第一列为物种名称；第二列为标本的采集编号或馆藏编号（所有以"USNM"为前缀的标本均收藏于史密森学会国家自然历史博物馆）。各采集样本的产地信息详见Hopkins 2011年发表于《Evolution》第65卷第3252-3273页的研究及其附表S1、S2。其余各列依次列出编号1至15的每个地标点的x、y坐标。地标点示意图详见ReadMe文件中的配图（可与图1对比，图1中的地标点为经镜像翻转后的编号）。缺失的地标点以"NA"标注。本次镜像翻转的基准线由地标点2和4确定。部分数据此前已发布于Dryad平台，因这些数据曾用于上述引用的《Evolution》期刊论文。
