Females solicit sneakers to improve fertilization success in the bitterling fish (Rhodeus sericeus)
Original language description
In most species there is greater variance in reproductive fitness among males than females. A consequence is the evolution of alternative male mating tactics, including sneaking behaviour whereby males attempt to mate with females courted by other males,which could undermine female choice. In bitterling (Rhodeus sericeus), fish that lay their eggs on the gills of living freshwater mussels, sneaking is common and successful. Here we show that female bitterling can significantly improve their fertility with an increase in the number of spawning partners. Females perform conspicuous behaviours associated with spawning more frequently close to sneakers, and spawn more eggs close to high-quality sneakers. This is the first time that females have been shownto engage in behaviour that increases the probability of sneaking, and raises the possibility of a sexual conflict over the number and source of ejaculates during spawning in this species.

Samice hořavky duhové (Rhodeus sericeus) se dvoří neteritoriálním samcům: strategie zvýšení oplozenosti jiker
Czech description
Experimentálně jsme testovali vliv přítomnosti neteritoriálních samců na chování samic hořavky duhové. Zjistili jsme, že samice se dvoří neteritoriálním samcům a podněcují je k oplození jiker. Touto strategií zvyšují oplozenost svých jiker. Zjištění má významné souvislosti pro evoluci pohlavních strategií a evoluci samčích reprodukčních strategií.
