Biplots of morphological data.

All 15 measurements were scaled by total length for each specimen (N = 45). Individuals were grouped into three groups representing 3 states NSW, VIC and TAS. Trendlines were added to each group. Note that TAS had only N = 5 samples. For body depth (BD1 and BD2) we indicate where possible sex, however dead individuals could not be sexed (majority of NSW specimens N = 13, and 3 from Eden). Symbols: Brown triangle NSW (open brown triangle female N = 2 and open brown rhomboid male N = 2), blue circle VIC male (open blue circle female N = 4) and black square TAS male (open black square female N = 4).

本数据集包含的15项测量指标均针对每份标本按总长度完成标准化处理，总样本量为N=45。所有个体被划分为三组，分别对应新南威尔士州（NSW）、维多利亚州（VIC）与塔斯马尼亚州（TAS）三个采样区域的种群。每组均添加了趋势拟合线。需注意，塔斯马尼亚州组的样本量仅为N=5。针对体高指标（BD1与BD2），我们尽可能对可鉴定的个体标注性别，但死亡个体无法完成性别鉴定；新南威尔士州组的标本共计N=13，其中3例采自伊登地区。图例说明如下：棕色三角代表新南威尔士州组（空心棕色三角为雌性，样本量N=2；空心棕色菱形为雄性，样本量N=2）；蓝色圆形代表维多利亚州组雄性（空心蓝色圆形为雌性，样本量N=4）；黑色方形代表塔斯马尼亚州组雄性（空心黑色方形为雌性，样本量N=4）。(ZIP)
