Controlling factors of phytoplankton distribution in the river–lake transition zone of a large lake

David Andrew Barry, Frédéric Charles Soulignac, Matthieu Fallet

River–lake transition zones have been identified as major drivers of phytoplankton growth. With climate change reducing the frequency of complete lake overturns, it is expected that the Rhône River, the main tributary to Lake Geneva (France/Switzerland), w ...

Nutrient pollution enhances productivity and framework dissolution in algae- but not in coral-dominated reef communities

Nils Rädecker, Hal Hunt Jones II

Ecosystem services provided by coral reefs may be susceptible to the combined effects of benthic species shifts and anthropogenic nutrient pollution, but related field studies are scarce. We thus investigated in situ how dissolved inorganic nutrient enrich ...

Patterns and Drivers of Extracellular Enzyme Activity in New Zealand Glacier-Fed Streams

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Tyler Joe Kohler, Stylianos Fodelianakis, Paraskevi Pramateftaki, Vincent Henri De Staercke, Matteo Tolosano, Michail Styllas, Martina Andrea Schön

Glacier-fed streams (GFSs) exhibit near-freezing temperatures, variable flows, and often high turbidities. Currently, the rapid shrinkage of mountain glaciers is altering the delivery of meltwater, solutes, and particulate matter to GFSs, with unknown cons ...

Measuring coral calcification under ocean acidification: methodological considerations for the 45Ca-uptake and total alkalinity anomaly technique

Thomas Krüger, Maoz Fine, Stéphanie Kéren Cohen

As the oceans become less alkaline due to rising CO2 levels, deleterious consequences are expected for calcifying corals. Predicting how coral calcification will be affected by on-going ocean acidification (OA) requires an accurate assessment of CaCO3 depo ...

When neighbours become competitors - Autotrophic assimilation rates of individual symbionts depend on local density when Stylophora pistillata is regularly fed

Anders Meibom, Thomas Krüger, Maoz Fine

The symbiosis between dinoflagellate microalgae and their cnidarian host represents the fundamental mechanism that allows zooxanthellate corals to access the inorganic nutrient pool of the surrounding seawater and conserve and recycle nutrients within thei ...

Diatom/copepod interactions in plankton: The indirect chemical defense of unicellular algae

Max-Planck-Institut fur Chemische Okologie, Hans-Knoll-Strasse 8, 07745 Jena, Germany. pohnert@ice.mpg.de Numerous coexisting species can be observed in the open oceans. This includes the complex community of the plankton, which comprises all free floating ...

Phytoextraction of heavy metals by hyperaccumulating and non hyperaccumulating plants

Claudia Cosio

Although phytoextraction using hyperaccumulating plants is seen as a promising technique, a lack of understanding of the basic physiological, biochemical, and molecular mechanisms involved in heavy metal hyperaccumulation prevents the optimization of the p ...

Hydroxyl radical/ozone ratios during ozonation processes. II. The effect of temperature, pH, alkalinity, and DOM properties

Urs von Gunten

The influence of temperature, pH, alkalinity, and type and concentration of the dissolved organic matter (DOM) on the rate of ozone (O-3) decomposition, O-3-exposure, . OH-exposure and the ratio R-ct of the concentrations of . OH and O-3 has been studied. ...
