Highly Dynamic Cellular-Level Response of Symbiotic Coral to a Sudden Increase in Environmental Nitrogen
Anders Meibom, Duncan Thomas Lindsay Alexander, Isabelle Domart-Coulon, Christophe Kopp
Metabolic interactions with endosymbiotic photosynthetic dinoflagellate Symbiodinium spp. are fundamental to reef-building corals (Scleractinia) thriving in nutrient-poor tropical seas. Yet, detailed understanding at the single-cell level of nutrient assim ...
American Society for Microbiology2013Optimizing turbine withdrawal from a tropical reservoir for improved water quality in downstream wetlands
Alfred Johny Wüest, Bernhard Wehrli
Large reservoirs in the tropics act as efficient nutrient traps and often develop hypoxic conditions in the hypolimnion. Both effects may have severe implications for aquatic ecosystems, such as limited primary production in downstream riparian agriculture ...
American Geophysical Union2013A single-cell view of ammonium assimilation in coral-dinoflagellate symbiosis
Anders Meibom, Isabelle Domart-Coulon, Christophe Kopp
Assimilation of inorganic nitrogen from nutrient-poor tropical seas is an essential challenge for the endosymbiosis between reef-building corals and dinoflagellates. Despite the clear evidence that reef-building corals can use ammonium as inorganic nitroge ...
2012Optofluidic microdevice for algae classification: a comparison of results from discriminant analysis and neural network pattern recognition
The early detection of changes in the level and composition of algae is essential for tracking water quality and environmental changes. Current approaches require the collection of a specimen which is later analyzed in a laboratory: this slow and expensive ...
2012Diatom/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 ...
2005Microbial size spectra from natural and nutrient enriched ecosystems
Microbial size spectra, including bacteria through nanophytoplankton, were measured by use of how cytometry across the western north Atlantic Ocean and during two nutrient enrichment studies: bottle enrichments in the Sargasso Sea and an in situ iron enric ...
