Tóth, Sándor: Monitoring dragonflies on the section of the Drava between Őrtilos and Vízvár (Insecta: Odonata) - Szitakötők monitorozása a Dráva mente Őrtilos és Vízvár közötti szakaszán (Insecta: Odonata)

TÓTH S.: MONITORING DRAGONFLIES 39 Examined variables In order to be able to determine the possible later changes owing to the power plant, the examination of particularly the following indices is justified: - The exact species composition, i.e. the number of occurring species. - The density per species. - The stages of the life cycle (imago, larva, exuvium). Results and conclusions The list of species detected in the sampling sites of monitoring between 2000 and 2004 on the section between Ortilos and Vízvár in systematical order (the taxons protected in Hungary are marked with one, the species listed in the Bern Convention with two asterisks).
