Abstract

V originále

Perla burmeisteriana is traditionally classified as an epipotamal indicator. But occurrence of this species was documented in all part of rhithral. The questions are: 1) is the epipotamal stretch home patch of Perla burmeisteriana, and rhithral zone is only refugium, where Perla burmisteriana population survives (epipotamal zones are often regulated and euthrophicated). 2) or home patch is wider (rhithral to epipotamal). The main factor influenced occurrence are structure of bottom (roughness), type of current, oxygen saturation. Water temperature is important but no more limiting. There is only limit of highest temperature about 25C during several days. Length of oviposition and time of emergence is not different in rhithral in altitude above 600 m and in epipotamal (metarhithral) in altitude about 150 - 300 m. It seems that rhithal zone, esp. upper part (epirhithral), is for Perla burmeisteriana refugium. Current adaptation of local populations is very constant and on the other hand the specimens could spread on surrounding habitats that means mainly downstream and occupied step by step original patch. This life strategy corresponds very well to metapopulation theory and patch dynamic concept.

In Czech

P.B. je tradičně klasifikována jako indikator epipotamalu. Výskyt larev zjišěny v posledních letech je však jiný. Hlavním faktorem určujícím výskyt bude struktura dna, typ proudění a množství kyslíku. Teplota nei již tak limitující. zDá se že vyšší úseky toku se stavájí pro tento druh ekologickým refugiem za regulované a znečištěné dolní toky.
