摘要

摘要：本研究采用基于二维标志的几何形态计量分析方法，研究了两种亲缘关系密切的刺猬——同色锥虫和鲁曼锥虫之间的头骨变异。为此，共对68个标本进行了评估：54个康氏E.concolor和14个鲁氏E.roumanicus。PCA、ANOVA和MANOVA分析结果显示，物种之间存在显著的形状差异，尤其是颅骨背侧。形状差异在颅骨背表面的神经颅和内脏颅骨区域以及下颌支和前臼齿区域最为显著。DFA测试在统计学上对相同物种平均数的零假设具有显著性，交叉验证得分高到足以区分物种。回归分析还显示，这两个物种在颅骨和下颌骨方面存在高度显著的异速性差异。最后，本研究表明，鲁马尼库斯不仅分布在土耳其的欧洲部分，而且分布在安纳托利亚西北部。

Discrimination of the sister hedgehog species Erinaceus concolor and E. roumanicus(Erinaceomorpha: Mammalia): a geometric morphometric approach

. Abstract: This study investigates skull variation between the two closely related hedgehog species, Erinaceus concolor and E. roumanicus by using geometric morphometric analyses based on 2-dimensional landmarks. For this purpose, a total of 68 specimens were evaluated: 54 E. concolor and 14 E. roumanicus. The results of PCA, ANOVA and MANOVA analyses showed significant shape differences between the species, especially for the dorsal cranium. Shape differences were most prominent on the neurocranium and viscerocranium regions of the dorsal surface of the cranium and in mandibular ramus and the premolar regions. DFA tests were statistically significant against the null hypothesis of equal species means and crossvalidation scores were high enough to distinguish the species. Regression analyses also showed highly significant allometric differences between the two species, for both crania and mandibles. Finally, this study indicates that E. roumanicus is not only present in the European part of Turkey, but also in northwestern Anatolia.

期刊介绍： The Turkish Journal of Zoology is published electronically 6 times a year by the Scientific and Technological Research Council of Turkey (TÜBİTAK). -Accepts English-language manuscripts in various fields of zoology including systematics, developmental biology, behaviour biology, animal models, molecular biology and molecular phylogeny, genomics, physiology (cell communication and signaling systems), biochemistry and immunohistochemistry, applied parasitology and pathology, nanobiotechnology, ecology, evolution, and paleontology of animal taxa. -Contribution is open to researchers of all nationalities. -Short communications are also welcome, such as reports of a preliminary nature or those including new records from specific localities or regions, and the editor reserves the right to decide that a paper be treated as a short communication. -The papers that deal with purely checklists, new host and non-regional new locality records will not be consider for publication. -Letters to the editor reflect the opinions of other researchers on the articles published in the journal. The editor may also invite review articles concerning recent developments in particular areas of interest.
