Morphological Diversification of Mesocyclops leuckarti (Claus, 1857)
Abstract
In this study, different populations of a copepod species, Mesocyclops leuckarti, were compared with their body size. Samples were taken from Asi River, Mehmetli Dam Lake, Yenişehir Lake, and Tahta Köprü Dam Lake, locating in east-south part of Turkey. Whole sexual dimorphism for the populations was changed from 1.56 to 1.62. Intra-population variability on body size by locations were changed as 3.85 % to 5.05 %. Intra-population variability was bigger in male than that of female populations in each water body. The same pattern was observed for inter-population variability among male populations (8.46 %) and female populations (8.04 %). Discriminant analysis (DFA) and SIMPER (Similarity Percentage) methods revealed that Cephalozom Length (CL) measurementwas the most distinguished measure leading discriminate among the male populations with 23.97 %. Abdomen (ABD) measurement was the most discriminative measure among female populations with 30.86 %. Based on the MANOVA, the differentiation in body size among the female populations was very significant (p<0.001), contrary to male populations (p>0.05).The Minimal Spanning Tree (MST) analysis showed that the specimen living in the pond and lake systems were closer than river systems in terms of body size diversification especially for female ones of copepods.
