Nieuwe slakken in een oud meer: vestiging van Lymnaea (Radix) auricularia tussen de endemen van het Baikalmeer

Lake Baikal is the oldest and deepest lake of the world and its isolated ecosystem has an extremely high, mainly endemic species richness. Recently, palearctic lymnaeids managed to establish populations within the endemic dominated snail communities of the steep, exposed shores. A morphological survey revealed high differentiation of the new populations. The pathways of introduction and possible ecological consequences are discussed.
