In the present study, cadmium (Cd) accumulation capabilities of aquatic macrophytes Ceratophyllum demersum, Bacopa monnieri and Rotala rotundifolia were determined after treating both individual and triple macrophytes. The macrophytes were treated with Cd at 0, 0.1, 1 and 10 mg/L concentrations in a controlled chamber for 12-days. Cadmium accumulations increased with increasing Cd concentration...

Submerged macrophytes respond to changes in the nutrient concentrations in their environment. In contrast to diatoms e.g., submerged macrophytes are capable of taking up nutrients from both the sediment pore water and the overlying water. Therefore, macrophytes can provide a more comprehensive assessment of river ecosystems. Two methods using submerged macrophytes to assess and monitor changes ...

[1] We measured dN signatures of macrophytes and particulate organic matter (POM) in six estuaries and three freshwater ponds of Massachusetts to assess whether the signatures could be used as indicators of the magnitude of land-derived nitrogen loads, concentration of dissolved inorganic nitrogen in the water column, and percentage of N loads contributed by wastewater disposal. The study focus...

Using multiple-choice feeding experiments, the selection of six species of macrophytes by the herbivorous rabbitfish Siganus fuscescens was examined. The rabbitfish showed distinct food choice in the laboratory; however, selection of macrophytes by S. fuscescens was not related to their absolute nutrient content (nitrogen, carbon, energy and ash free dry mass). Nutrient assimilation estimates s...

Stoichiometric homeostasis of element composition is one of the central concepts of ecological stoichiometry. We analyzed concentrations of macroelements (C, N, P, Ca, K, Mg, S), microelements (Cu, Fe, Mn, Mo, Ni, Zn) and beneficial elements (Na, Se, Si) in submerged macrophytes, water and sediments across 20 Yunnan plateau lakes. We predicted that tissue element composition in submerged macrop...

Hydrophilie, or water-Ioving, macrophytes characterize wetland ecosystems, indicating prerequisite conditions of hydrie soils and sufficient hydrology. The presence of such macrophytes is a key descriptor in multiple wetland definitions (Lewis 2001a) and macrophytes may be further used to actually describe partieular types of wetlands, such as cattail marshes. Macrophytes contribute significant...

Lodge, D.M., 1991. Herbivory on freshwater macrophytes. Aquat. Bot., 41: 195-224. Conventional wisdom holds that live macrophytes are rarely consumed and are functionally unimportant in aquatic food webs. With a review of the literature, I first demonstrate that macrophyte biomass, productivity, and species composition is often influenced by a variety of vertebrate and invertebrate grazers. Man...

This article reports on a study to determine the influence of aquatic macrophytes on the formation of phytoplankton and zooplankton communities as well as hydrohemical features in different regions of the Kuibyshev reservoir (Republic of Tatarstan, Russia). It was found that aquatic macrophytes have sanative effect resulting in the reduction amount of some chemical pollutants (petrochemicals, n...
