The spiny-cheek crayfish Orconectes limosus (Rafinesque, 1817) is one of the most problematic invasive crayfish species in Europe. Here we report the first occurrence of spiny-cheek crayfish in Slovenia, 300 km upstream from the previously known records in the mouth of Drava River in Croatia. The species was not expected to colonize this area for at least two decades. This new isolated population will significantly alter our predictions of the ongoing colonization of the Drava River basin in Austria, Slovenia and Croatia.
Résumé
L'écrevisse américaine Orconectes limosus (Rafinesque, 1817) est l'une des espèces d'écrevisses invasives les plus problématiques en Europe. Nous rapportons ici la première occurrence de l'écrevisse américaine en Slovénie, 300 km en amont des sites précédemment connus dans l'embouchure de la Drava en Croatie. L'espèce n'était pas censée coloniser cette zone pendant au moins deux décennies. Cette nouvelle population isolée modifiera considérablement les prédictions de la colonisation en cours du bassin de la Drava en Autriche, en Slovénie et en Croatie.
