Aquatic plants mediate ecological processes in aquatic habitats, specifically predator–prey (bluegill sunfish (Lepomis macrochirus Rafinesque)-macroinvertebrate) interactions. Macroinvertebrate colonization is directly and indirectly influenced by substrate heterogeneity, interstitial space, and surface complexity. Exotic invasive plant species, such as Hydrilla verticillata L.F. Royle, may alter the available structure in aquatic habitat by creating a shift to a homogeneous habitat, thus… 
Effects of invasive macrophytes on freshwater fish and macroinvertebrate communities: the role of invasive plant traits
TLDR
Three invasive traits largely responsible for negative effects on fish and macroinvertebrate communities are identified: increased growth rate, allelopathic chemical production, and phenotypic plasticity allowing for greater adaptation to environmental conditions than native species.
Impact of three aquatic invasive species on native plants and macroinvertebrates in temperate ponds
TLDR
A strong negative relationship to invasive species cover and invertebrates abundance was found, probably due to unsuitable conditions of the detritus for invertebrate colonization.
Ostracod (Crustacea) colonization of a native and a non-native macrophyte species of Hydrocharitaceae in the Upper Paraná floodplain (Brazil): an experimental evaluation
TLDR
The results show that H. verticillata might provide favorable habitats for native ostracod assemblages, and cumulative curves, which permit to eliminate effects of abundance on richness, indicated a significantly higher number of ostracOD species on H.–verticilata.
Effects of an Invasive Alien Poaceae on Aquatic Macrophytes and Fish Communities in a Neotropical Reservoir
TLDR
U. arrecta is a source of concern for biodiversity conservation because it has negative influences on both assemblages when it is well developed, which is true in the later stages of the invasion process.
The invasive submerged macrophyte Hydrilla verticillata as a foraging habitat for small-sized fish
TLDR
Although H. verticillata does not affect the foraging activity, it has the potential to affect the assemblages of small-sized fish through changes in the proportions of food resources.
Effects of a native and a non-native macrophyte species of Hydrocharitaceae on Chironomidae and Oligochaeta assemblages structure doi: 10.4025/actascibiolsci.v35i3.10855
TLDR
The results suggest that despite being a recent colonizer in the upper Parana river habitats, the non-native species H. verticillata seems to provide favorable conditions for the establishment of native assemblages of Chironomidae and Oligochaeta.
Propagule pressure, invasibility of freshwater ecosystems by macrophytes and their ecological impacts: a review of tropical freshwater ecosystems
In this review, we aim to draw parallels between the principal concepts of invasion biology, developed mainly for terrestrial plants in temperate regions, with findings for macrophytes recorded in
The Effects of Macrophyte Tannins on the Epiphytic Macroinvertebrate Assemblages in Sandy Lake, Pennsylvania
TLDR
Examining the communities of macroinvertebrates on five species of aquatic plants in Sandy Lake, Pennsylvania, found that there was no significant difference in macro invertebrate density, biomass, or species richness between M. spicatum and the other macrophytes.
The invasive macrophyte Hydrilla verticillata causes taxonomic and functional homogenization of associated Chironomidae community
TLDR
Although H. verticillata did not cause changes neither in Chironomidae taxonomic richness nor on taxonomic and functional composition, its spread may drive the simplification of species and functional traits of associated ChironOMidae communities.
Biotic resistance by snails and fish to an exotic invasive aquatic plant
TLDR
Results indicate that biotic resistance may play an important role in reducing the early establishment of H. verticillata in the lakes of this Neotropical floodplain, however, the disturbance caused by the exotic shredder fish may have an undesirable effect at larger scales because it stimulated the production of propagules that may spread to other connected aquatic ecosystems.

A comparison of water-column macroinvertebrate communities in beds of differing submersed aquatic vegetation in the tidal freshwater Potomac River
TLDR
Results support the hypothesis that water-column macroinvertebrates are greatly enhanced in the presence of macrophytes, and the ecological significance of the less substantial differences in macroinVertebrates between macrophyte beds requires further study.
Largemouth Bass Diets in Two Aquatic Plant Communities
TLDR
The results suggested the architecture of a particular species of aquatic plant may contribute to differences in diets of adult and juvenile largemouth bass.
Factors influencing invertebrate communities in prairie wetlands: a multivariate approach
We examined the relationships between invertebrate community structure and a number of biotic and abiotic variables in 19 semipermanent prairie wetlands. We tested whether aquatic invertebrate
Effects of an introduced aquatic plant, Hydrilla verticillata, on benthic communities in the Upper Chesapeake Bay.
TLDR
Transplants of Hydrillas and sampling from natural Hydrilla and unvegetated patches indicate that this plant enhances the abundances of a variety of benthic fauna, and emphasize the potential importance of introduced plants in altering community characteristics.
Methods for Management of Nonindigenous Aquatic Plants
TLDR
Numerous terrestrial plant communities have been invaded by nonindigenous (NI) plant species that have disrupted community dynamics and ecosystem processes and invoke similar approaches to their management.

Factors influencing macroinvertebrate colonization of seasonal wetlands: responses to emergent plant cover.
TLDR
It is demonstrated that invertebrates communities may be different within plant stands with heterogeneous amounts of emergent cover, and management practices that alter the structure of wetland vegetation can influence macroinvertebrate communities colonizing seasonal marshes.

TLDR
The greater similarity of the bluegill diets to the epiphytic than to the benthic macroinvertebrate assemblages suggested that bluegills obtai...
Effects of Habitat Complexity on Macroinvertebrate Colonization of Artificial Substrates in North Temperate Lakes
TLDR
The results were consistent with the hypothesis that the more complex, 3-dimensional artificial substrate, with its greater substrate heterogeneity, surface complexity, and interstitial space, will support a more diverse and abundant macroinvertebrate community in lakes compared to the less complex, 2- dimensional artificial substrate.
Epiphytic Macroinvertebrates on Dominant Macrophytes in Two Central Florida Lakes
TLDR
The quantities of epiphytic macroinvertebrates were greater on floating and submergent plants than on emergent plants and there were significant (P <0.05) temporal variations in the abundance of invertebrates; however, consistent temporal trends were not evident.
