Overleeft Corbicula strenge Winters in Nederland?

The recently invaded clam Corbicula fluminea survived the exceptionally severe winter of 1995-1996, when the river Rhine near Wageningen (Province of Gelderland), was for a relatively long period of time completely frozen over. The large numbers found suggest that they had not reinvaded the site during 1996 from warmer habitats upstreams. In January 1997, after a period of severe frost lasting for more than a week, live animals were collected from water of barely more than 0°C, showing that the animals can survive these conditions in situ.
