Abstract

The aim of the study was to evaluate the shape of the male and female New Zealand Rabbit cranium. For this purpose, geometric morphometry method was used. A total of 10 female and 10 male New Zealand Rabbit craniums were used. The skulls were photographed in a dorsal, ventral and lateral view, and the mandible was photographed in a lateral view. Homologous landmarks were marked on the photographs. Consensus graphs were created by TpsRelw (Version 1.70) program. Additionally, principal component analysis and relative warp analysis were performed. As a result of the study, principal components explained 34.813%, 57.225% and 42.427% of the total shape difference in the dorsal, ventral and lateral views of the skull, respectively. In the first principal component graph obtained as a result of principal component analysis, no significant clustering was observed between in gender. According to the graphics obtained in the MorphoJ program, inter-individual variation was detected mostly in the viscerocranium, followed by the neurocranium. We believe that this study will contribute to morphological and archaeological studies on rabbit skulls.
新西兰兔头盖骨的几何形态分析
这项研究的目的是评估雌雄新西兰兔的颅骨形状。为此采用了几何形态测量法。共使用了 10 个雌性和 10 个雄性新西兰兔头盖骨。对头骨的背侧、腹侧和侧视图进行了拍照,并对下颌骨进行了侧视图拍照。照片上标注了同源地标。共识图由 TpsRelw(1.70 版)程序绘制。此外,还进行了主成分分析和相对翘曲分析。研究结果显示,主成分分别解释了头骨背侧、腹侧和侧视图总形状差异的 34.813%、57.225% 和 42.427%。在主成分分析得出的第一个主成分图中,没有观察到性别间的明显聚类。根据 MorphoJ 程序得到的图形,个体间的差异主要体现在粘颅骨上,其次是神经颅骨。我们相信,这项研究将有助于兔头骨的形态学和考古学研究。
