Removal of heavy metals from industrial effluents by the submerged aquatic plant Myriophyllum spicatum L. Ghent University
The potential use of Myriophyllum spicatum L. for the removal of Co, Ni, Cu and Zn from industrial effluents was studied. The removal kinetics, tolerance and accumulation capacity of the submerged aquatic plant were assessed. Removal of Cu and Zn was similar and occurred rapidly with time whereas removal of Co and Ni was slower. Plant growth was not adversely affected during the 12 weeks of exposure to the wastewater. Cobalt, Ni, Cu and Zn ...
Experimental evidence for the decline of submerged vegetation in freshwater ecosystems by the invasive Chinese mitten crab (Eriocheir sinensis) University of Antwerp Vrije Universiteit Brussel
The Chinese mitten crab (Eriocheir sinensis) is a damaging invader which is designated as a species of Union Concern within the European Union. A negative impact of the crabs on macrophyte vegetation in lowland rivers is suspected but not yet proven or quantified. We have performed a mesocosm study that combines a density gradient of Chinese mitten crabs (0, 0.3, 1.0 and 2.5 ind. m(-2)) with chemical stress (2350 mu g EDTA L-1 + 258 mu g ...
Effects of climate change on growth and development of Berula erecta as model species for freshwater macrophytes University of Antwerp
Freshwater ecosystems are one of the most diverse, but also one of the most threatened ecosystems in the world. Aquatic macrophytes are highly affected by consequences of climate change like increased concentrations of dissolved organic carbon (DOC) and carbon dioxide (CO2), but also changes in flow dynamics and eutrophication. Knowledge on the effects of DOC and CO2 on macrophytes, and especially their interaction effects with other effects of ...
Tissue hydrogen peroxide concentration can explain the invasiveness of aquatic macrophytes University of Antwerp
In recent years, an invasive macrophyte, Egeria densa , has overwhelmingly colonized some midstream reaches of Japanese rivers. This study was designed to determine how E. densa has been able to colonize these areas and to assess the environmental conditions that limit or even prevent colonization. Invasive species ( E. densa and Elodea nuttallii ), and Japanese native species ( Myriophyllum spicatum , Ceratophyllum demersum , and Potamogeton ...
