Influence of temperature and salinity on heavy metal uptake by submersed plants

Environmental Pollution, 2005
Submersed plants can be useful in reducing heavy metal concentrations in stormwater, since they can accumulate large amounts of heavy metals in their shoots. To investigate the effects of water temperature and salinity on the metal uptake of two submersed plant species, Elodea canadensis (Michx.) and Potamogeton natans (L.), these plants were grown in ...

Submersible pumping plant

Journal of the Institution of Electrical Engineers, 1960
Submersible pumping units have been developed to a sufficiently high degree of reliability and efficiency to capture a large part of the field previously held by the conventional borehole pump with surface motor. The paper commences with a description of the submersible pump and the submersible motor as separate units, together with sectional drawings,

Antibacterial compounds in estuarine submersed aquatic plants

Journal of Experimental Marine Biology and Ecology, 2006
Estuarine seagrasses often exist in nutrient-rich waters and thus might benefit from mechanisms to control exterior growth of epiphytic microorganisms. In this study, we tested extracts from three estuarine seagrass species, Potamogeton pectinatus L. (sago pondweed), Potamogeton perfoliatus L. (redhead grass) and Ruppia maritima L.

Coexistence and interference in two submersed freshwater perennial plants

Oecologia, 1983
Interactions between two codominant submersed freshwater perennial plants, Eleocharis acicularis (L.) R. and S. and Juncus pelocarpus forma submersus Fassett, were studied in a softwater lake. Analysis of segregation indicated a nonrandon arrangement of individual rosettes of each species with respect to rosettes of the other species.

Positive feedback favors invasion by a submersed freshwater plant

Oecologia, 2012
The submersed macrophyte Utricularia inflata has invaded lakes in northern New York State, thereby threatening native isoetids such as Eriocaulon aquaticum. Isoetids often dominate and modify softwater lakes due to their capacity to oxidize sediment and thus influence solute mobilization. Greenhouse experiments tested the hypotheses that U.

Do submersed plants enhance microbial activity in sediment?

Aquatic Botany, 2001
Abstract The effects of three submersed plant species ( Elodea canadensis Mixch., Myriophyllum alterniflorum L. and Lobelia dortmanna L.) on bacterial activity and microbial biomass in ambient sediment were measured under laboratory conditions with special reference to organic carbon release through the plant roots.

Vertical secondary flows in submersed plant‐like arrays

Limnology and Oceanography, 1999
Obstructions that protruded from a laboratory test bed into the benthic boundary layer were exposed to gradients in longitudinal velocity (δu/δz) that produced vertical pressure gradients along the surface of the obstruction. These pressure gradients generated vertical secondary flows that may have ecological significance for benthic fauna and aquatic ...

Quantification of epiphyte removal efficiency from submersed aquatic plants

Aquatic Botany, 1997
Abstract Three independent methods were used to quantify the efficiency of a mechanical agitation technique for the removal of epiphytes from four submersed macrophyte species. Time course samples were collected for epiphytic chlorophyll, dry weight, and algal and diatom cell counts following cumulative agitation periods of 10, 30, 60, 90, and 120 s.

Methods for assessing the toxicity of herbicides to submersed aquatic plants

Pest Management Science, 2006
AbstractA new test design for the non‐axenic submergent aquatic macrophytes Elodea canadensis Michx. and Myriophyllum spicatum L. has been developed for potential use in herbicide toxicity testing. For the non‐axenic cultures, the best growth conditions were observed in the Elendt‐M4 medium in which no growth of algae or bacteria was observed. Cuttings
