Virus-bacterium interactions in water and sediment of West African inland aquatic systems.
The ecology of virioplankton in tropical aquatic ecosystems is poorly documented, and in particular, there are no references concerning African continental waters in the literature. In this study, we examined virus-bacterium interactions in the pelagic and benthic zones of seven contrasting shallow inland waters in Senegal, including one hypersaline lake. SYBR Gold-stained samples revealed that...
متن کاملEffects of Linuron to an Aquatic Plant in Sediment-dosed Test Systems
The availability of standardised methodologies to assess the environmental risks of pesticides to non-target plants is currently limited. Aquatic plant test guidelines are only available for algae and Lemna. These studies may not be sufficient especially in the case when contamination via sediment is an important exposure pathway. The present study was initiated to investigate the effects of ex...

متن کاملEffect of pesticides on nitrification in aquatic sediment.
The aim of this work was to study the effect of the herbicides glyphosate, nonanoic acid, and dichlorprop-P and the insecticides potassium oil, malation and Pyretrin and their combinations on nitrification. Nitrification was measured in slurries from the eutrophic and shallow Brabrand Lake (Aarhus, Denmark), by inhibiting oxidation of nitrite to nitrate with chloride. All herbicides and insecti...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
