However, Pieczynska (2003) studied the damage inflicted on a population of E. canadensis by the snail Lymnaea stagnalis and concluded that although the snail caused a substantial reduction in biomass and severe damage to E. canadensis, the plant fragments remaining after grazing showed a high capacity to regenerate new plants.

Erhard and Gross (2006) suggested that the production of allelochemicals that interfere with the growth of cyanobacteria and algae by both E. canadensis and the closely related E. nuttallii could play at least some role in the success of these two species as invasive species.

When it was first observed in Europe, in Ireland in 1836, it was suggested that one of the pathways of introduction could be through timber-trade commodities (Marshall, 1852 and 1857 in Brundu, 2015). USA. Hygraula nitens is a New Zealand native moth with aquatic larvae that feed on submerged aquatic plants. Four varieties are recognized by Missouri Botanical Garden (2019): var. Elodea canadensis is a submerged aquatic plant of slower flowing rivers, native to North America. During autumn, apices cease to elongate and come to bear tightly clustered dark green leaves, which contain increased starch and are slightly more cuticularized than the normal foliage leaves.
