Boundary-layers around bladed aquatic macrophytes

Hydrobiologia, 1997
This paper describes a model of the diffusive boundary-layer around anaquatic macrophyte blade. Nutrient uptake at the base of the modelledboundary-layer was examined using previously published laboratory data. Theanalysis showed that, over the outer velocity range 0.01–0.16ms−1, nutrient uptake varied between that predicted byflat-plate boundary-layer

Photosynthetic carbon assimilation in aquatic macrophytes

Aquatic Botany, 1991
Abstract In submerged aquatic macrophytes the relationship between net photosynthesis and carbon concentration in the water often follows a less gradual pattern than anticipated assuming simple Michaelis-Menten kinetics. This indicates that other factors than the activity of the carboxylation enzymes are important in the regulation of photosynthesis ...

Amino Acids in Aquatic Macrophytes

Zeitschrift für Pflanzenphysiologie, 1977
Summary Ranunuculus aquatilis, Ranunclus fluitans, Elodea canadensis, Potamogeton pectinatus, Potamogeton natans and Zannichellia palustris were collected from homogenous populations in their natural environment. 1. Fewer amino acid components were detected than usually found in plants with the described automatic method. 2. The absolute

Macrophytes promote aquatic insect conservation in artificial ponds

Aquatic conservation, 2019
Farmland ponds promote regional aquatic biodiversity; however, optimally managing these ponds requires knowledge on how the biodiversity differs between ponds across catchments with different land uses. This study investigated the response of macrophytes,

Managing water quality with aquatic macrophytes

Reviews in Environmental Science and Bio/Technology, 2008
The principal sources of water for human use are lakes, rivers, soil moisture and relatively shallow groundwater basins. Water quality in lakes and reservoirs is subjected to the natural degradation, processes of eutrophication and the impacts of human activities.

Aquatic Macrophytes in White Lake, Michigan

Journal of the Environmental Engineering Division, 1977
Samples of plants were analyzed for carbon, hydrogen, nitrogen, potassium, and phosphorus. The findings reveal that the areal extent of the macrophytes approaches one-fifth of the lake total surface area and the macrophyte biomass is equal in magnitude to the phytoplankton. The White Lake macrophyte community does not appear to be limited by phosphorus
