| In Florida canals, M. cornuarietis can consume large quantities of aquatic plants of many genera, including Najas, Myriophyllum, Elodea, Cabomba, and, when abundant, can eliminate rooted vegetation (Hunt 1958; McCann et al. 1996). However, reports of recent damage to Florida ecosystems are lacking (Howells et al. 2006). | ||
