dc.description.abstractTHE REPRODUCTIVE CYCLE OF NON-NATIVE SPECIES IS INDICATIVE OF THEIR CAPACITY FOR DISPERSAL, INVASION, AND COMPETITION, AND THE ALTERATION IN BIODIVERSITY. CORBICULA SPP. ARE SUCCESSFUL INVADERS OF AQUATIC ECOSYSTEMS. WE STUDIED THE REPRODUCTIVE CYCLE OF CORBICULA LARGILLIERTI FROM A PAMPEAN STREAM, ARGENTINA, AT ITS SOUTHERN DISTRIBUTION IN SOUTH AMERICA. SPECIMENS WERE COLLECTED MONTHLY FROM JANUARY 2003 TO APRIL 2005 AND PROCESSED USING TRADITIONAL HISTOLOGICAL TECHNIQUES. THREE GONADAL STAGES (ACTIVE GAMETOGENESIS, MATURE, AND SPAWNED) WERE RECOGNIZED. IN THE STUDIED POPULATION, MOST INDIVIDUALS WERE HERMAPHRODITIC WITH A DOMINANT FEMALE GONADAL PORTION. THE THREE GONADAL STAGES WERE OBSERVED DURING THE WHOLE SAMPLING PERIOD WITH RAPID GONADAL RECOVERY; NO RESTING PERIOD WAS OBSERVED. FIVE OOCYTE SPAWNING EVENTS WERE RECOGNIZED, OCCURRING IN AUTUMN AND SPRING. EXPANDING THE KNOWLEDGE OF REPRODUCTIVE FEATURES OF THE CORBICULA LARGILLIERTI ALLOWS THE UNDERSTANDING OF CURRENT DISTRIBUTIONS. THE RESULTS HIGHLIGHT THE DIFFICULTY OF IDENTIFYING PATTERNS OF GAMETE RELEASE AND SPAWNING BEHAVIOR IN THIS INVASIVE SPECIES, AS IT IS RECORDED FOR OTHER CORBICULA SPP.
