It is recognized that dissolved organic matter (DOM) plays an utmost role in aquatic ecosystems by binding trace metals and influencing their speciation, bioavailability and detrimental effects. DOM is considered to protect the aquatic microorganisms from ...
Induced chemical defense reactions are widespread in marine brown algae. Despite the evidence that the biosynthesis of defense metabolites can be up-regulated upon herbivory, we do not know how this regulation of biosynthetic pathways to secondary metaboli ...
Harmful algal blooms in both freshwater and marine environments pose significant challenges for humans, livestock and aquatic food webs. Over the last 50 years, several authors proposed that small mol. iron chelators (siderophores) could be responsible for ...
The present study provides results on the influence of humic substance (HS) photoalteration on lead availability to the freshwater microalga Chlorella kesslerii. The evolution of the free lead-ion concentrations measured by the ion exchange technique [Pb]( ...
Background: Scleractinian corals are currently a focus of major interest because of their ecological importance and the uncertain fate of coral reefs in the face of increasing anthropogenic pressure. Despite this, remarkably little is known about the evolu ...
In this paper, we will report our recent development of a new type of OptoFluidic Microscope (OFM) that is capable of delivering resolution beyond the diffraction limit of light. Accurate control of the sample translation is accomplished by adopting an opt ...
This paper presents the results of an effort to label calcium carbonates formed by marine organisms with stable isotopes to obtain information about the biomineralization processes. The growing skeleton of the scleractinian coral Porites porites was labele ...
There has been growing concern about the way cultivating biomass for the production of agro-biofuels competes with food production. To avoid this competition biomass production for biofuels will, in the long term, have to be completely decoupled from food ...
The present study examines the role of humic acid, as a representative of dissolved organic matter, in Cd(II), Cu(II) and Pb(II) speciation and biouptake by green microalgae. Cellular and intracellular metal fractions were compared in the presence of citri ...
A detailed budget of the fluxes of bio-available phosphorus (bio-P) was established for the ultra-oligotrophic Lake Brienz (Switzerland) and its catchment. Lake Brienz is a cold, deep oligotrophic peri-alpine lake that receives an annual load of approximat ...
