Intensive fish ponds as ecological traps for dragonflies: an imminent threat to the endangered species Sympetrum depressiusculum (Odonata: Libellulidae)

Popis výsledku v původním jazyce

We investigated the effects of putative ecological traps on the threatened dragonfly Sympetrum depressiusculum and the common closely related species S. sanguineum in a Central European agricultural landscape. Observations of adult behavior were used toparameterize GLMs examining the attractiveness of five fish ponds (three fish breeding and two intensive) to each species. We also counted exuviae at each pond as a measure of each species´ survival. We used GLMMs to determine which factors affected selection of oviposition sites and the environmental factors resulting in ecological traps for each species. All five ponds were attractive to ovipositing pairs of both species, although they were largely unsuitable for subsequent development. Our results provide evidence that intensive fish ponds act as ecological traps for both species. We believe that cutting of the vegetation surrounding trap habitats could be an effective way to decrease their attractiveness to a wide range of dragonfly
