Abstract
We studied the variation of morphometric traits in Ground Beetle Carabus aeruginosus F.-W. Beetles were sampled in Kemerovo region in the gradient of urbanization: the city, its suburbs and natural biotopes outside the city. We used General Linear Models, Principal Component Analysis and Multidimensional Scaling to show that all environmental factors (anthropogenic disturbance, vegetation of biotope) contributed significantly into the size variation of the beetles. Females and males reacted in different ways to the environmental factors. These phenomena lead to the different values of size sex dimorphism (SSD). Factors “City” and “Suburbs” decreased the value on SSD in the species investigated, but factor “Meadows” increased SSD. Our results indicated shape sex dimorphism (ShSD) in Carabus aeruginosus as well.
