Human altered ecosystems: suitable habitats as well as ecological traps for dragonflies (Odonata): the matter of scale

Popis výsledku v původním jazyce

We present findings from a 10 year study that intensively monitored odonate fauna in the Upper Silesian industrial coal region. We evaluated qualitative changes in the dragonfly assemblages on 10 patches using a modified dragonfly biotic index. Data analysis was supplemented by a model examining population dynamics of the threatened dragonfly Leucorrhinia pectoralis, using the capture-mark-recapture method. We show that dynamics of environmental conditions in secondary habitats are reflected in population dynamics of dragonfly populations and assemblages. As frequency of L. pectoralis population extinctions within the patch is considerable and independent of size and spatial isolation of single habitats, these can be regarded as ecological traps. Nevertheless, the metapopulation dynamics may be a key adaptation of dragonflies to frequent freshwater habitat disturbances. We suggest that local extinctions are effectively balanced with (re )colonization of newly emerging freshwater habita
