Dispersal of Corbicula fluminea: factors influencing the invasive clam's drifting behavior
Two Asian clam populations were compared and differed in flotation behaviour assisted by a mucous drogue line. Genetic variability and seasonality were assumed to explain the inconsistencies. Populations do not seem genetically distinct, thus mucous production is possibly influenced by microevolutionary events, not being a necessary condition for clam reproduction to occur.
