  • Based on the compilation of numerous data obtained with various methods, the paper discusses primary productivity (PP) in the Atlantic Sector of the Southern Ocean. Deviations from zonality law were observed in the waters of frontal zones
  • . Factors determining PP in the region, as well as correlation of PP and productivity on higher trophic levels, are discussed.

  • Predicting above-ground net primary productivity of tropical rainforests from evapotranspiration data
  • In the thermodynamic theory of aquatic ecosystems the non-linear relations between rates and affinities of biological processes, such as primary production, respiration, grazing etc. can be determined using an optimun principle. Especially
