Population consequences of behaviour in the European bitterling (Rhodeus sericeus Cyprinidae)

Original language description

The European bitterling is a freshwater fish with an unusual spawning symbiosis with freshwater mussels. Female bitterling possess long ovipositors that they use to place their eggs onto the gills of a mussel. Males fertilise the eggs by releasing sperminto the inhalant siphon of the mussel. The embryos develop inside the mussel for approximately a month, eventually leaving the mussel as actively swimming larvae. Because they use a discrete spawning site that can be readily manipulated they represent an ideal model for linking reproductive decisions with population dynamics. Bitterling have been used in field and large-scale pool experiments, in combination with modelling and population and genetic studies to investigate the population consequences ofbehaviour. Here we show how male mating tactics, female mate and oviposition decisions, and aggressive interference competition among juveniles, may have significant impacts on bitterling population size and population genetics.

Vliv chování na populační parametry hořavky duhové

Czech description

Tato studie shrnuje výzkum týkající se vlivu chování hořavek na populační parametry. Souhrnný článek ukazuje, proč jsou hořavky cenným modelem pro výzkum tohoto typu a ukazuje příklady experimentů a modelování parametrů na populační parametry. Studie sezabývá samčími strategiemi, samiční volbou, volbou místa pro kladení jiker, a agresivitou mezi juvenilními jedinci.
