20.500.12556/DiRROS-19999 Temperature dependence of planktonic metabolism in the subtropical North Atlantic Ocean The temperature dependence of planktonic metabolism in the subtropical North Atlantic Ocean was assessed on the basis of measurements of gross primary production (GPP), community respiration (CR) and net community production (NCP), as well as experimental assessments of the response of CR to temperature manipulations. Metabolic rates were measured at 68 stations along three consecutive longitudinal transects completed during the Malaspina 2010 Expedition, in three different seasons. Temperature gradients were observed in depth and at basin and seasonal scale. The results showed seasonal variability in the metabolic rates, the highest rates being observed during the spring transect. The overall mean integrated GPP / CR ratio was 1.39 ± 0.27 decreasing from winter to summer, and the NCP for the subtropical North Atlantic Ocean during the cruises exhibits net autotrophy (NCP > 0) in about two-thirds (66%) of the total sampled communities. Also, we reported the activation energies describing the temperature dependence of planktonic community metabolism, which was generally higher for CR than for GPP in the subtropical North Atlantic Ocean, as the metabolic theory of ecology predicts. Furthermore, we made a comparison of activation energies describing the responses to in situ temperature in the field (EaCR = 1.64 ± 0.36 eV) and those derived experimentally by temperature manipulations (EaCR = 1.45 ± 0.6 eV), which showed great consistency. morje plankton fitoplankton klorofil trofični status anoksije true false true Angleški jezik Ni določen Neznano 2024-08-01 16:27:34 2024-08-01 16:27:34 2024-08-02 03:50:44 0000-00-00 00:00:00 2014 0 0 Izv. znanstv. članek; str. 4529-4540 no. 1 Vol. 11 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2014-08-27 574 1726-4170 10.5194/bg-11-4529-2014 3191887 http://www.biogeosciences.net/11/4529/2014/bg-11-4529-2014.html 1 705dbdb5-5001-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27801 RAZ_Garcia-Corral_L.S._2014.pdf RAZ_Garcia-Corral_L.S._2014.pdf 1 B2A7ADDA15BE67BF84DFDE752D33DFF5 bffcd632e695d5933e4c93006977dc9e415e671b9a8354846eb1e128668c19d1 bd3228d5-5001-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27802 http://dx.doi.org/10.5194/bg-11-4529-2014 0 c90ea510-5001-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27803 Nacionalni inštitut za biologijo 0 0 0
