in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

Submerged macrophyte communities are frequently subjected to disturbance of various frequency and strength. However, there is still little experimental evidence on how mechanical disturbance affects the performance and species composition of such plant communities. In a greenhouse experiment, we constructed wetland communities consisting of five co-occurring clonal submerged macrophyte species ...

The hydrilla tip mining midge, Cricotopus lebetis Sublette (Diptera: Chironomidae), is a biological control agent of the invasive aquatic weed hydrilla, Hydrilla verticillata (L.f.) Royle (Hydrocharitaceae). Mass rearing of the midge for augmentative releases can be compromised by competition from the adventive hydrilla leafcutter moth, Parapoynx diminutalis Snellen (Lepidoptera: Crambidae). Th...

Este artículo describe el análisis realizado a la capacidad de las lentejas agua (Lemna minor) fitorremediar concentraciones hierro, comparándolas con hydrilla (Hydrilla verticillata) durante siete días. Para realizar este estudio se utilizó declorada, cual le agregó sulfato ferroso (II) heptahidratado (FeSO4∙7H2O) y analizó diferentes características químicas físicas del agua. Tanto como prese...

Abstract Hunting down the eagle killer: Vacuolar myelinopathy is a neurological disease affecting wildlife — including iconic bald in United States. Its cause has been elusive for decades, but its occurrence linked to cyanobacterium Aetokthonos hydrillicola colonizing invasive aquatic plant Hydrilla verticillata . In recent study, we found that A. produces novel highly toxic biindole alkaloid (...

The effects of harvesting intensity on the growth Hydrilla verticillata (L. fil.) Royle as well water quality were studied in controlled experiments to provide a reference for managing submerged vegetation and purifying water. results showed that had significant effect recovery shoot H. height. harvested group recovered completely or mostly after two harvests, but time was significantly longer ...

Climate change is projected to increase stress for many coastal plant communities. Along large portions of the North American coast, habitat degradation from anthropogenic changes to the environment already threaten the community structure of tidal marshes and submerged aquatic grass beds. The potential loss of ecological services historically provided by these communities has been a long-stand...

Aquatic macrophytes have been widely studied because of their capability of absorbing contaminants from water and their subsequent use in biomonitoring. This study presents a comparison of Cr accumulating potential of submerged aquatic plants viz Vallisneria spiralis and Hydrilla verticillata. These plants were treated with various concentrations of treated tannery effluent collected from UASB,...

The submersed monocot Hydrilla verticillata (L.f.) Royle is a facultative C(4) plant. It typically exhibits C(3) photosynthetic characteristics, but exposure to low [CO(2)] induces a C(4) system in which the C(4) and Calvin cycles co-exist in the same cell and the initial fixation in the light is catalyzed by phosphoenolpyruvate carboxylase (PEPC). Three full-length cDNAs encoding PEPC were iso...
