Odonata; dragonflies; dispersal ability.

However the individual species dispersal ability deserves special attention mainly because of the negative impact of human induced changes on freshwater ecosystems. This study is focused on Central European dragonflies, because there is a high concentration of very experienced odonatologists in this region. It is more difficult to estimate dispersal ability of distant taxa than closely related species. This study supports the widespread awareness of limited dispersal abilities of habitat generalists. Although there are a variety of life-history groups between both suborders, the majority of species with limited dispersal abilities are from the suborder Zygoptera. Mediterranean elements often referred to as those expanding due to global warming embody higher dispersal abilities than Siberian elements. Lentic species may benefit from the stable conditions of standing waters in comparison to lotic ones although this preference is not so strong according to our analysis.
