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.

Abstract
Bu çalışmada, bir kopepod türü olan Mesocyclops leuckarti nin vücut büyüklüğü farklı popülasyonları arasında karşılaştırıldı. Örnekler Türkiye nin Güney Doğusunda yer alan Asi Nehri, Mehmetli Baraj Gölü, Yenişehir Gölü ve Tahta Köprü Baraj Gölü'nden alındı. Popülasyonları için genel eşeysel dimorfizim 1,56 ile 1,62 arasında değişti. Lokasyonlara göre, popülasyonlar içi vücut büyüklüğündeki değişim % 3,85 ile % 5,05 arasında değişmiştir. Her bir su kütlesinde erkeklerin popülasyonlar içi değişimleri dişilere göre daha fazla idi. Aynı model erkek popülasyonları (% 8,46) arasında ve dişi popülasyonları (% 8,04) arasında da gözlemlenmiştir. Diskriminant analizi (DFA) ve SIMPER (Benzerlik Yüzdesi) yöntemleri, Cephalozom Uzunluk (CL) ölçümünün, erkek popülasyonları arasında % 23,97 ile ayrışmaya yol açan en belirgin ölçüm olduğunu ortaya koydu. Abdomen (ABD) ölçümü dişi popülasyonlar içinde % 30,86 ile en fazla ayrışmaya yol açan ölçüm idi. MANOVA' ya göre, dişi popülasyonları arasında vücut büyüklüğündeki farklılaşma, erkek popülasyonların aksine (p>0,05) çok anlamlıydı (p <0,001). Minimal Yayılma Ağacı (MST) analizi, vücut büyüklüğü farklılaşması açısından özellikle kopepod' ların dişileri için, gölet ve göl sistemlerinde yaşayan bireylerin nehir sistemlerinde yaşayan bireylere göre birbirlerine daha yakın olduğunu göstermiştir.
