We present an analysis of seasonal variations in the trophic pathways carbon a highly productive coastal upwelling region Humboldt current system off Chile. Seasonal changes phytoplankton, protozooplankton, and bacteria biomass, along with rates primary production (PP), bacterial growth, secondary production, vertical particle fluxes, feeding by omnivorous mesozooplankton, carnivorous gelatinous zooplankton were determined from July 2004 to June 2005. Phytoplankton biomass PP maximal during...

We studied the effects of future climate change scenarios on plankton communities a Norwegian fjord using mesocosm approach. After spring bloom, natural were enclosed and treated in duplicates with inorganic nutrients elevated to pre-bloom conditions (N, P, Si; eutrophication), lowering 0.4 pH units (acidification), rising 3°C temperature (warming). All nutrient-amended treatments resulted phytoplankton blooms dominated by chain-forming diatoms, reached 13–16 μg chlorophyll (chl) l−1. In...

Abstract Mixotrophs combine photosynthesis with phagotrophy to cover their demands in energy and essential nutrients. This gives them a competitive advantage under oligotropihc conditions, where nutrients bacteria concentrations are low. As the for mixotroph depends on light, competition between mixo- heterotrophic bacterivores should be regulated by light. To test this hypothesis, we incubated natural plankton from ultra-oligotrophic Eastern Mediterranean set of mesocosms maintained at 4...

The use of ultrathin polymer films as sensoactive layers in chemical sensors has received great interest recent years due to many advantages such the wide choice polymeric system (polymer types and/or combination, dopants conducting polymers, etc), and possibility tailoring properties these terms sensitivity selectivity by an efficient control film formation process [1]. Among techniques used for formation, self-assembly (SA) offers several since substrate can take any form size, deposition...
