We studied the direct effects of CO2 and related changes in seawater carbonate chemistry on marine planktonic organisms a mesocosm experiment. In nine outdoor enclosures (~11 m3 each), partial pressure (pCO2) was modified by an aeration system. The triplicate treatments represented low (~190 parts per million volume (ppmV) CO2), present (~410 ppmV high (~710 CO2) pCO2 conditions. After initial fertilization with nitrate phosphate bloom dominated coccolithophorid Emiliania huxleyi occurred...

Abstract Lack of access to clean water and adequate sanitation continues be a major brake on development. Here we present the results 12-month investigation into dynamics Escherichia coli , commonly used indicator faecal contamination in supplies, three small, rural catchments Laos, Thailand Vietnam. We show that land use hydrology are controlling factors E. concentrations streamwater relative importance these two varies between dry wet seasons. In all catchments, highest were observed...
Background The global burden of diarrhea is a leading cause morbidity and mortality worldwide. In montane areas South-East Asia such as northern Laos, recent changes in land use have induced increased runoff, soil erosion in-stream suspended sediment loads, potential pathogen dissemination. To our knowledge, few studies related incidences to catchment scale hydrological factors river discharge, loads Fecal Indicator Bacteria (FIB) Escherichia coli, together with sociological hygiene...
The pools of dissolved (DOM) and particulate organic matter (POM) transparent exopolymeric particles (TEP) were studied along two sampling gradients in the lagoon New Caledonia relation to residence time water masses. efficiency transfer material from phase via TEP formation, indicating physicochemical reactivity matter, was investigated. DOM, POM, concentration increased gradients, but their relative proportions varied. contribution pool POM 20% 60%, most oligotrophic stations more...
Viruses attract increasing interest from environmental microbiologists seeking to understand their function and role in coral health. However, little is known about main ecological traits within the holobiont. In this study, a quantitative qualitative characterization of viral bacterial communities was conducted on mucus seven different species Van Phong Bay (Vietnam). On average, concentrations viruses bacteria were, respectively, 17- twofold higher than surrounding water. The examination...
Abstract The Red River is the second largest river in Viet Nam and constitutes main water source for a large percentage of population North Nam. Here we present results an annual survey Escherichia coli (EC) Total Coliforms (TC) basin, objective this work was to obtain information on faecal indicator bacteria (FIB) numbers over cycle and, secondly, determine die-off rates these bacterial indicators. Monthly observations at 10 stations from July 2013–June 2014 showed that TC EC reached as...
