Ecological aspects of the macroinvertebrates associated with two submersed macrophytes in Lake Kariba
… Fenzl are the most common and abundant submerged macrophytes in shallow inshore waters of Sanyati Basin, Lake Kariba. Lagarosiphon is structurally more complex than Vallisneria. This study considered the macroinvertebrate assemblages associated with the two plant species with respect to …

Water Quality Spatial Heterogeneity in Wastewater Stabilization Ponds at Elevated pH
… of epipelic filamentous 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 …

Differential Utilization of Allochthonous and Autochthonous Carbon By Aquatic Insects of Two Shrub-Steppe Desert Spring-Streams: A Stable Carbon Isotope Analysis and Critique of the Method
… aufwuchs, filamentous green algae, emergent macrophytes, and submerged macrophytes. The wide isotopic variance among autochthonous carbon sources, some of which were consistently in the expected allochthonous isotopic range, made it impossible to quantify differential utilization of …

Ecology of benthic macroinvertebrates in experimental ponds
… indicated that the ponds were oligotrophic. Submerged macrophytes colonized and became established in most of the ponds during year 2. A few noninsect taxa were not present in expected numbers, probably due to lack of efficient dispersal mechanisms. Fifteen metrics were analyzed by a …

Culturing Vallisneria americana for Restoration Efforts
Robust Vallisneria americana was cultured for restoration purposes. Preliminary studies, with various iron treatments, were conducted to ascertain the amount of phosphorous release into the water column from sediments. There was a significant difference in the amount of phosphorous released if …

Aquatic macrophyte-derived biomarkers as palaeolimnological proxies on the Tibetan Plateau
… focus on aquatic macrophyte-derived biomarkers. Submerged aquatic macrophytes have to be considered to significantly influence the sediment organic matter due to their high abundance in many Tibetan lakes. They can show highly 13C-enriched biomass because of their carbon metabolism and it is …

Bioaccumalation of metals in mullet from Mhlathuze Estuary and the effect of Cu and Pb on the uptake kinetics,haematology and acid-base balance of Liza dumerelii.
… blephariskios and Apsendes digitalis) and submerged macrophytes (Zostera capensis) and analysing for metal accumulation. Seven metals, i.e. Al, Cr. Cu, Fe, Mn, Pb and Zn were analysed in the abovementioned abiotic and biotic compartments following standard nitric/perchloric acid digestion …

Food web regulation under different forcing regimes in shallow lakes
… either in a clear-water or turbid state, where macrophytes and phytoplankton dominate, respectively. Both states can stabilize themselves through various mechanisms. These two alternative states and stabilizing mechanisms are integrated in the complex ecosystem model PCLake, which was used to …
