Dorcadion micans J. Thomson, 1867 (Coleoptera: Cerambycidae) Pronotumunda Geometrik Morfometri Kullanarak Eşeysel Dimorfizm

Eşeysel dimorfizm, hayvanlarda fenotipik varyasyonun en önemli kaynaklarından biridir. Birçok türdeki böcekler için eşeysel özelliklerin ifadesi büyük farklılıklar gösterir. Bu çalışmada, Türkiye'de endemik tür olan Dorcadion micans J. Thomson, 1867 (Coleoptera: Cerambycidae) 'da pronotumun eşeysel büyüklük ve şekil dimorfizmini analiz ettik. Sonuçlarımız, pronotumda istatistiksel olarak eşeysel büyüklük ve şekil dimorfizmini göstermiştir. Erkekler dişilerden daha küçük pronotum boyutuyla birlikte daha uzun ve daha keskin bir pronotum şekline sahiptir. Çok değişkenli regresyon sonuçları, büyüklüğün cinsiyetler arasında pronotum şeklindeki farklılaşma üzerinde göz ardı edilebilir bir etkiye sahip olduğunu göstermiştir.

Sexual Dimorphism of the Pronotum in Dorcadion micans J. Thomson, 1867 (Coleoptera: Cerambycidae) Using Geometric Morphometrics

Sexual dimorphism is one of the most notable sources of phenotypic variation in animals. The expression of sexual traits varies widely for many species of insects. In this study, we analyzed the sexual size and shape dimorphism of pronotum in Turkish endemic species, Dorcadion micans J. Thomson, 1867 (Coleoptera: Cerambycidae). Our results have showed that there is statistically significant sexual size and shape dimorphism in pronotum. Males have a longer and sharper pronotum shape with smaller pronotum size than females. Multivariate regression results indicated that size has negligible influence on the differentiation in pronotum shape between sexes.
