08 Hoffmann & Shirriffs 2002, Wing traits

This data file contains x and y coordinates of nine landmarks for wings and different traits related to wing shape for 19 Drosophila serrata populations collected in 2001. Measurements were taken for up to 10 isofemale lines per population. Wing_aspect was defined as wing length (the linear distance between landmarks 3 and 6) divided by the square root of wing area (here taken to be centroid size). Angle (outer-wing aspect) was defined as the angle between the vectors from landmarks 2 and 8 and the vector between landmarks 4 and 8. Wing proportion (outer_wing aspect) was defined as the linear distance between landmarks 2 and 4 divided by wing length (Fig. 2). Note longitudes in data are approximate.

Evolution 56: 1068-1073本数据集涵盖2001年采集的19个锯足果蝇（Drosophila serrata）种群的翅部9个地标点（landmark）的x、y坐标，以及与翅型相关的多项性状数据。每个种群最多开展10个单雌系（isofemale line）的测定。 翅展比（Wing_aspect）定义为翅长（地标点3与6之间的直线距离）除以翅面积的平方根（此处以形心大小（centroid size）计算）。 外翅角（outer-wing aspect）定义为地标点2至8的向量与地标点4至8的向量之间的夹角。 翅比例（outer_wing aspect）定义为地标点2与4之间的直线距离与翅长的比值（见图2）。 请注意：数据中所记录的经度为近似值。 若使用本数据集，请引用以下原始文献： 霍夫曼，阿里·A. 与希里夫斯，珍妮弗（2002）。锯足果蝇（Drosophila serrata）翅型的地理变异。《进化》（Evolution）56卷：1068-1073
