Effects of temperature on lipid synthesis of diatom Chaetoceros Pseudocurvisetus and the Northern Adriatic plankton community

We investigated the influence of rising temperature on lipid production by Northern Adriatic plankton community. To test how marine phytoplankton would respond to predicted increasing temperature we conducted monoculture batch experiments in laboratory on model diatom Chaetoceros pseudocurvisetus at five different temperatures from 10 to 30C. We have chosen Chaetoceros pseudocurvisetus as a model culture since it is important component of NA phytoplankton community, but also Chaetoceros genus of diatoms is most abundant in wide range of marine ecosystems. We conducted annual sampling of the Northern Adriatic particulate matter that covers the same temperature range as for the batch experiments. Samples were taken during a year on a monthly basis. Lipid were characterized with thin–layer chromatography–flame ionization detection and electrospray ionization (ESI) MS and tandem mass spectrometry (MS/MS). Data are supported by particulate organic carbon (POC), chlorophyll a (Chl a) concentrations and phytoplankton taxonomy and cell abundances
