In some parts of the United States, native beavers (Castor canadensis) have reduced the abundance of M. aquaticum as much as 90% through direct consumption.

Parrot feather cover negatively affected invertebrate taxa richness and abundance. Uninvaded ponds supported a more distinct invertebrate community, including species (e.g Ephemeroptera) that are rare or missing from invaded ponds.

Predation/Herbivory

Experimental
|
Field
|
Substantial differences in community composition of invertebrate taxa were found between native and non-native macrophyte species. There was a higher relative abundance of cladocerans, chironomids, and gastropods in the native vegetation shifting towards dominance by amphipods in both parrotfeather and Brazilian elodea. We also found lower relative abundance of taxa from the Odonata, Ephemeroptera, and Hemiptera orders (class Insecta) associated with these non-native plants
