Sexual selection for male dominance reduces opportunities for female mate choice in the European bitterling (Rhodeus sericeus)

Original language description

We experimentally separated intrasexual (male-male interference competition) and intersexual (female choice) components of sexual selection in a freshwater fish, the European bitterling. We compared the roles of multiple morphological and behavioural traits in male success in both components of sexual competition, and their relation to male reproductive success, measured as paternity of offspring. Body size was important for both female choice and male-male competition, though females also preferred males that courted more vigorously. However, dominant males often monopolised females regardless of female preference. In conclusion, we showed that even though larger body size was favoured in both intersexual and intrasexual selection, male-male interference competition reduced opportunities for female choice. Females, despite being choosy, had limited control over the paternity of their offspring.

Pohlavní výběr hořavky duhové preferuje samčí dominantní chování a snižuje pravděpodobnost úspěšné samičí volby

Czech description

Testovali jsme vliv dvou komponent pohlavního výběru ? samičí volby a soubojů mezi samci. Zjistili jsme, že úspěšnost v soubojích mezi samci je pro samčí reprodukční úspěšnost významně důležitější než samičí volba; většina jiker byla oplozena samci, kteří dokázali monopolizovat zdroje a samci vybraní samicemi byli z reprodukce vyloučeni nedostatkem zdrojů k odložení jiker.
