    Notes: Protozoa are the main consumers of heterotrophic bacteria in aquatic habitats. The numbers of these bacteria and protozoa in oligotrophic areas of the open ocean are low, and current methods lack the sensitivity to assess rates of bacterivory in such waters. A new method is proposed for estimating bacterivory on dual radioactively labelled natural bacteria using living ambient prey bacteria and separation of predators from prey by fractionation. This approach is sufficiently sensitive to measure the consumption of less than 1% of the labelled bacteria during a 13-h incubation period. When tested on samples collected from 27 stations in mesotrophic and oligotrophic regions of the North and South Atlantic Oceans, about 17% of metabolically active bacteria were grazed per day and about 60% of consumed prey biomass labelled with 14C-leucine was retained by the predators.

    Description: The database collected using the Continuous Plankton Recorder (CPR) operated by SAHFOS covers a long time span (surveys are on-going since 1946) and the whole North Atlantic, including the North Sea. It is therefore a unique tool to investigate changes in the planktonic community composition. Key publications have documented, for example, changes in zooplankton and chlorophyll abundance over the past decades. However, the data on calcareous plankton archived in the CPR database have not yet been exploited. The publication of the "Atlas of Calcifying Plankton" by SAHFOS and EPOCA begins to fill this gap and is therefore most timely. I am convinced that the scientific community will use this short preliminary description of the data available to investigate the drivers of the changes (or lack of thereof) reported in the Atlas.
