Seasonal change in the opportunity for sexual selection
Original language description
We investigated seasonal changes in variation in reproductive success, measured as the opportunity for sexual selection, using parentage analysis in 20 experimental populations of the bitterling, a small freshwater fish with a promiscuous, resource-basedmating system. We showed that although the largest males sired most offspring over the entire reproductive season, variation in reproductive success and hence the opportunity for sexual selection was low at the start of the season but increased significantly at its end. This seasonal difference probably arose from the superior competitive endurance of large males and from a higher temporal clustering of reproductively active females at the start of the breeding season than later in the season. The spatial distribution of oviposition sites had a negligible effect on the variation in reproductive success. We discuss the potential implications of our results for the importance and strength of sexual selection in natural populations.

Sezónní změny v potenciálu pohlavního výběru
Czech description
V této studii jsme sledovali sezónní změny v reprodukční úspěšnosti (měřené indexem příležitosti k pohlavnímu výběru) u 20 experimentálních populací hořavky duhové. Zjistili jsme, že potenciál k pohlavnímu výběru je silně sezónní a v práci diskutujeme možné implikace pro teorii pohlavního výběru v přírodních populacích.
