Potential of gravel pit lakes for dragonfly reproduction


An analysis of variance (ANOVA) was performed to investigate a potential difference in dispersal ability between species that breed in gravel lakes and species that only visit them. Breeding and visiting potential were then investigated in parallel with the different environmental parameters via correlations. The results showed that there was no significant difference in dispersal ability between lake breeding and lake visiting species. The distance to the next river and the next lake are determining factors in the reproduction of dragonflies. Visitor potential correlates with all parameters of habitat quality, complexity of shoreline and riparian habitats and percentage of water by about 30%.
