Abstract
In the present study, we studied the morphological variations in four populations of Oxynoemacheilus angorae distributed in three basins of Turkish inland waters using a geometric morphometric technique. For this purpose, a total of 55 specimens were collected from the Kızılırmak, Sakarya and Marmara basins. To extract body shape data, the left side of the specimens was photographed, and 15 landmark points on the 2D pictures were defined and digitized. After generalized procrustes analysis, the body shape data were analyzed using multivariate analyses, such as principal component analysis, canonical variation analysis and cluster analysis. The deformation grids were used to show how the body shape changed. Based on the results, two groups, namely Nevşehir and Ankara, by having a deeper body and head and a somewhat longer caudal peduncle, and Yalova and Eskişehir due to lower body and shorter caudal peduncle were clustered. Based on the results, O. angorae adapts itself to different habitats by adjusting head and body depth and caudal peduncle length based on habitat parameters.
