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.

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

In Lake Porta, Italy, canals invaded by Myriophyllum aquaticum resulted in the loss of plant species richness, diversity and taxonomic distinctiveness. This also resulted in decreases of arthropod species richness. Certain species became more abundant, such as the invasive crayfish Procambarus clarkii, mosquitoes, and malacostraca
