Red Squirrel GMM data

Data underlying geometric morphometric analysis of red squirrels (Sciurus vulgaris) from Great Britain collected between 1948 and 2020. All specimens housed at National Museums Scotland, Edinburgh. Accession numbers in file names. All data collected by by Kim Chandler between 2021 and 2022. 161 crania were scanned in 3D with an Artec Space Spider structured light scanner (Artec3D, Luxembourg) and saved as STL files. 388 mandibles were photographed in 2D with a Nikon 3200 DSLR camera (Nikon Corporation, Tokyo).Landmarks and semi-landmarks were collected from the crania in 3D using Avizo Lite v9.2 (Thermo Fisher Scientific, Waltham, MA), and from the mandibles in 2D using TPSdig2 (Rohlf, 2015). Geometric morphometric analyses were carried out with the Arothron package in the R statistical environment.

本数据集包含对大不列颠地区红松鼠（Sciurus vulgaris）的几何形态计量分析所依据的数据，该数据集的收集时间跨度为1948年至2020年。所有标本均存放在苏格兰国家博物馆，爱丁堡。文件名中包含登记编号。所有数据由Kim Chandler于2021年至2022年间收集。共扫描了161个颅骨，使用Artec Space Spider结构光扫描仪（Artec3D，卢森堡）进行3D扫描，并以STL格式保存。388个下颌骨使用尼康3200 DSLR相机（尼康公司，东京）进行2D摄影。通过Avizo Lite v9.2（赛默飞世尔科技，沃尔瑟姆，马萨诸塞州）在3D颅骨上，以及使用TPSdig2（Rohlf，2015）在2D下颌骨上收集了标志点和亚标志点。几何形态计量分析是在R统计环境中使用Arothron软件包进行的。
