Abstract
In 2017, we investigated the population dynamics and flying activity of the south-east European endemic dragonfly species Cordulegaster heros Theischinger, 1979. This research was conducted in the ...

Cordulegaster heros Theischinger, 1979 is a flagship species of dragonfly observed in closed riverine habitats at low altitudes in the Carpathian Mountains
To gain insight into the species’ population dynamics, we set out an experiment based on markrelease-recapture methods (MRR)

Summary
Cordulegaster heros Theischinger, 1979 is a flagship species of dragonfly observed in closed riverine habitats at low altitudes in the Carpathian Mountains. The habitat requirements of this species are fairly well known (Boudot & Kalkman, 2015), but its distribution across Slovakia or, in the Carpathians is still not well understood (Holuša & Kúdela, 2010). There is little knowledge of the species’ population in particular habitats in Slovakia. Mark-release-recapture methods are commonly used in various entomological studies to estimate population dynamics. They can serve as an estimation tool for survival of adult caddisflies (White & Henschen, 1978), to calculate dispersal abilities of threatened butterflies (Fric, Hula, Klimova, Zimmermann, & Konvicka, 2010) or to detect biological changes in
