Established but not spreading: the tropical invasive snail Melanoides tuberculata in a geothermally warmed channel in temperate Southern Pampas.

Melanoides tuberculata is a freshwater snail native to Old World tropical areas but has invaded tropical and subtropical regions around the world. In Argentina, populations established in natural environments were reported from northeastern tropical provinces. Here we report for the first time the presence of M.

Dealing with a hyper-successful neighbor: effects of the invasive apple snail on exotic and native snails in South America.

is a successful invader and also a competitor and predator of other snails and may play a key role in structuring freshwater snail communities both in its native and invaded range. In the present study we evaluated the contact and distant effects of in its native range on exotic ( and ) and native snails (, , and ). Habitat use was affected in , and by contact effects of , whereas survival was only affected in through combined contact and distant effects.
