Life History of a Population of Protonemura intricata (Ris, 1902) (Insecta, Plecoptera) in a Constant Temperature Stream in Central Europe
Abstract The nymphal biology (life cycle, secondary production and feeding) of a population of Protonemura intricata was studied in a calcareous stream with almost constant temperature (7–8 °C) through the year at Prosiek valley (Chočské Vrchy Mts., West Carpathians, Slovakia). The results were comp...
