Résumé :	The effects of simulated saltwater intrusions on the growth and survival of the freshwater angiosperm, Vallisneria americana Michx., from the Caloosahatchee estuary (southwest Florida, USA) were examined experimentally using indoor mesocosms. Intrusions were simulated by raising salinity in the mesocosms to 18parts per thousand for varying durations and then returning the salinity to 3parts per thousand. In separate experiments, exposures of short duration (1, 5, 11, and 20 d) and long duration (20, 30, 50, and 70 d) were examined. Plants held at a constant 3parts per thousand served as controls. Mortality was proportional to the duration of exposure. Statistically significant (p
