A possible evolutionary lag in the relationship between freshwater mussels and European bitterling

Original language description

Coevolutionary dynamics between European bitterling fish, Rhodeus amarus, and freshwater unionid mussels, which bitterling parasitize by laying eggs on their gills, were experimentally tested. In a series of experiments, fish preference and mussel responses in parasites and hosts of recent (Europe) and ancient (Asia) sympatry were compared. R. amarus readily oviposited into all mussel species tested. However, fish that laid their eggs on the gills of Asian Anodonta woodiana suffered a dramatic reductionin reproductive success compared to fish that oviposited on the gills of the European Unio pictorum, U. tumidus, Anodonta anatina, and A. cygnea. This difference was the result of egg ejection behaviour by mussels rather than the suitability of internalgill environment for bitterling embryo development. The data support a coevolutionary arm race between bitterling and mussels and point to an evolutionary lag in the relationship between R. amarus and its European hosts.

Evoluční zpoždění ve vztahu mezi hostitelskými mlži a hořavkou duhovou

Czech description

Studovali jsme koevoluční dynamiku vztahu mezi hořavkou duhovou (Rhodeus amarus) a jejími hostiteli, sladkovodními mlži. Experimentálním přístupem jsme zjistili, že hořavky v Evropě využívají evolučně naivní hostitele, kteří se ještě neumí bránit pomocívyhazovacího chování. Oproti tomu v Asii, kde hořavky a mlži žijí sympatricky po několik milionů let, jsou obranné mechanismy mlžů dobře vyvinuty.
