A Distinction of Some Cyprinid Species from Tigris River Basin According to Scales by Geometric Morphometric Methods

Abstract

In this study, a total of 86 (31♀♀, 55♂♂) cyprinid specimens belonging to the species, Luciobarbus mystaceus, Arabibarbus grypus, Luciobarbus esocinus and Carasobarbus luteus, were collected from the Tigris River near Cizre town. The size (as centroid size) and shape of scale separately were analyzed by 2D geometric morphometric methods. The size and shape of species were different but not for sex, according to ANOVA. Mahalonobis length of CVA results shows that only the difference between Luciobarbus esocinus and Carasobarbus luteus was not significant. DFA results based on T2 all species scale shape differences were significant except Luciobarbus esocinus and Carasobarbus luteus.

Dicle Nehir Sistemindeki Bazı Cyprinid Türlerinin Pullarından Geometrik Morfometrik Yöntemle Ayırt Edilmesi

Abstract

Bu çalışmada, Cizre ilçesi yakınlarındaki Dicle Nehri'nden Luciobarbus mystaceus, Arabibarbus grypus, Luciobarbus esocinus ve Carasobarbus luteus türlerine ait toplam 86 (31♀♀, 55♂♂) cyprinid örneği toplanmış ve büyüklüğü (centroid olarak) boyut ve pul şekli ayrı ayrı 2D geometrik morfometrik yöntemlerle analiz edilmiştir. Türlerin boyutu ve şekli farklıydı, ancak ANOVA'ya göre cinsiyet için farklı değildi. CVA sonuçlarının Mahalonobis mesafesine göre, sadece Luciobarbus esocinus ve Carasobarbus luteus arasındaki farkın anlamlı olmadığını göstermektedir. Luciobarbus esocinus ve Carasobarbus luteus dışında T2'ye dayalı DFA sonuçları tüm türlerin pul şekil farklılıkları önemliydi.
