Herbivore resistance in inavasive and native Myriophyllum spicatum and Myriophyllum heterophyllum
… and invasive samples of the aquatic angiosperms, Myriophyllum spicatum and Myriophyllum heterophyllum. M. spicatum is native in Europe, Asia and north Africa and invasive in much of North America. When fed on by the ecologically significant herbivore, Acentria ephemerella, M. spicatum plant tips …

Establishment and Competitive Ability of Nelumbo Lutea in Relation to Myriophyllum Spicatum
… 0.5, 1.0, and 1.5 m depths. Nelumbo lutea and Myriophyllum spicatum populations were monitored for one season in a 0.7 ha pond to track changes in species dominance. Myriophyllum spicatum dominated early, and N. lutea dominated from July through October, suppressing M. spicatum at all depths. …

Studies on the autecology of Myriophyllum aquaticum in the South-Western Cape Province
Aquatic macrophytes are an integral part of any freshwater ecosystem. In addition to being primary producers, they assist in nutrient circulation and provide shelter and spawning areas for many other forms of associated animal life (Nichols and Keeney, 1973; De Marte and Hartman, 1974).

THE ECOLOGY OF A SUBMERSED MACROPHYTE, MYRIOPHYLLUM HETEROPHYLLUM: COMPETITION FOR NUTRIENTS WITH PHYTOPLANKTON AND SEASONAL CHANGES IN TISSUE MINERAL CONTENT
<p>Myriophyllum heterophyllum is a nuisance, submersed hydrophyte in New Hampshire. First observed in Lake Winnipesaukee, New Hamsphire during the 1960s, the plant infested over 22 miles of the lake's shoreline by 1980. Circumstantial evidence suggests that M. heterophyllum was accidently …

Interactions Among Invasive Species in Lakes: a Mesocosm Experiment
… georgianus, BMS), and Eurasian water-milfoil (Myriophyllum spicatum, EWM), species that commonly co-occur. All three of these species can be very abundant and two (EWM and RC) are known to be individually damaging. The current study evaluated the impacts and interactions between these three …

Trophic Interactions And The Efficacy Of Milfoil Weevils For Biocontrol Of Eurasian Watermilfoil In Wisconsin Lakes
<p>Eurasian water-milfoil (Myriophyllum spicatum L., henceforth “EWM”) is the most heavily managed nuisance submersed aquatic plant in the United States. EWM’s rapid spring growth and formation of dense surface mats inhibits native macrophyte communities, serves as poor-quality habitat for fish and …

Feeding Behavior, Food Consumption, Growth, and Survival of Hybrid Grass Carp (Hypophthalmichthys nobilis x Ctenopharyngodon idella) In South Dakota
… pectinuatus. Ceratophyllum demersum and Myriophyllum spicatum were not consumed. Under field conditions N. guadalupensis also appeared to be preferred while C. demersum was not. Feeding behavior, daily consumption, growth, and survival were also evaluated in the two stockwater …

Water Quality Spatial Heterogeneity in Wastewater Stabilization Ponds at Elevated pH
… algae (Oedogonium) and submerged macrophytes (Myriophyllum, Potamogeton. The third study presented a novel approach to numerically model WSPs that attempted to reproduce the pH, DO, NO3-, total alkalinity, and PO43- observations taken in 2014. The model was the first of its kind to model pH …

Assessing the Influence of Different Inland Lake Management Strategies on Human-Mediated Invasive Species Spread
… mussels and Eurasian watermilfoil (<i>Myriophyllum spicatum</i>), use recreational boaters as their primary vector of dispersal. Control efforts in the past have focused on boater education efforts and boat washing stations and inspections, yet these can be expensive methods with …

Big data for the benefit of aquatic invasive species management
… of two prolific invaders (e.g., Dreissena and Myriophyllum species). Next, identifying lakes that are vulnerable to invasion provide an opportunity for early detection and intervention. I used machine learning models to predict the presence of five aquatic invaders that have spread across the …

Investigating the distribution of Nitellopsis obtusa in Ontario Lakes and its role as an ecosystem engineer
… associations with other macrophyte taxa such as Myriophyllum spicatum. In combination, these findings indicate that N. obtusa may be an ecosystem engineer in invaded lakes by affecting key lake elements and altering community composition throughout the LAFW community.

AN INVESTIGATION OF AQUATIC MACROPHYTE-BASED AQUATIC WASTEWATER TREATMENT SYSTEMS FOR TEMPERATE CLIMATES (ELODEA NUTTALLII, PHOTOSYNTHESIS, NUTRIENT BUDGET, ACTIVE TRANSPORT, NITRIFICATION)
… macrophytes (Elodea nuttallii, Lemna minor, Myriophyllum heterophyllum, Ceratophyllum demersum) were evaluated as candidates. The hydraulic, organic, and nutrient loadings to the reactors were similar to design values for water hyacinth (Eichornia crassipes) systems. Nitrification occurred on …
