Capoeta umbla (Heckel, 1843)’NIN PULLARINDA CİNSİYET, YAŞ VE MEVSİME BAĞLI VARYASYONLARIN GEOMETRİK MORFOMETRİK YÖNTEMLERLE İNCELENMESİ

Bu çalışmada Dicle Nehri’nden toplam 82 (67♀♀, 15♂♂) Capoeta umbla türüne ait balıklardan yanal çizginin ve dorsal yüzgecin arasındaki alandan alınan ve yaş tespiti yapılan pullardan bir tanesi Canon SX7 model binokülerde 40X büyütmede binokülere takılı Olympus dijital kamera ile fotoğrafları çekilmiş ve tpsDig ver. 2.26 programı kullanılarak 6 landmark alınmıştır. MorphoJ ver. 1.06d ve PAST 3.11 programları kullanılarak ANOVA (Varyans Analizi), PCA (Temel Öğeler Analizi), CVA (Kanonik Varyans Analizi) ve DFA (Ayrışım Fnonksiyonu ) analizleri yapılmıştır. Analizler sonucunda boyut (CS: Centroid Size) ANOVA bakımından cinsiyet ve yaş grupları arasında fark yeterli (p<0.05) bulunmuş ancak şekil ANOVA bakımından gruplar arasında fark (p>0.05) bulunmamıştır. CVA ve DFA sonucu II-IV, II-V yaş grupları ve sonbahar-kış ve sonbahar-ilkbahar grupları arasında Mahalanobis mesafesi yeterli düzeyde (p<0.05) farklı bulunmuştur.

A SURVEY ON SCALE OF Capoeta umbla (Heckel, 1843) BY GEOMETRIC MORPHOMETRIC METHODS DEPEND ON GENDER, AGE AND SEASON VARIATIONS

In this study, a total of 82 (67♀♀, 15♂♂) Capoeta umbla samples from the same location in the River of Tigris and ages of scales taken from area between lateral line and dorsal fins of fishes were determined and just one scale from each fish sample photographed by an Olympus digital camera with Canon SX7 model binocular under the same conditions with 40Xmagnification and then six landmarks were taken by using tpsDig ver. 2.26 software. Then, ANOVA (Analysis of Variance), PCA (Principal Component Analysis), CVA (Canonical Variance Anlysis) and DFA (Discriminant Function Analysis) analysis were conducted by MorphoJ ver. 1.06d and PAST 3.11,. According to the results of the analyses, there was a significant difference between gender and age groups in terms of gender and size (CS: Centroid Size) ANOVA, however, no difference was found in terms of the shape ANOVA of the samples. Also, there was a significant difference between Mahalanobis distance of II-IV, II-V age groups and Autumn-Winter, Autumn-Spring of season groups.
