127 ben rejlik, hanem inkább abban, hogy segít rámutatni azokra a varianciát okozó tényezőkre, amelyek biológiailag is jelentősek lehetnek (Lebreton és mtsai 1992). Esetünkben arra, hogy a hímek két csoportja között a becsült túlélési és a visszafogási rátában különbség van. Ez az eredmény kiindulópontja lehet további vizsgálatoknak, ahol a különbség tényének megerősítésén túl megfelelő predikciókkal vizsgálni lehet az eltéréseket kiváltó és magyarázó tényezőket is.

Nyíregyháza, Sóstói út 31/b, HUNGARY Abstract: Survival and recapture rates of Orthetrum coerulescens individuals of a closed population were studied by mark-recapture methods along a slow-flowing canalised creek called Kutas-fScsatoma in June, 2000. Relationship between mating success and fluctuating asymmetry was also investigated. Survival rate of unpaired males differed significantly from that of paired ones on the first two days after marking. Survival rate of both unpaired and paired males became constant later. Recapture rate differed in the two groups and changed in time and it could be explained by the time spent with observation. Neither the forewings nor the hindwings differed significantly in their fluctuating asymmetry values between unpaired and paired males. Harvey I F., Walsh, K. J.
