Virtual Special Issue: Zooplankton Feeding Methodology
Methods for investigating zooplankton feeding have been the focus of a considerable body of papers in the Journal of Plankton Research . The collection of papers in this virtual special issue focuses on recent articles on a range of new approaches to quantifying feeding and digestion.
The wider context is provided by the first three review articles, which consider microzooplankton grazing, the impact of changing climate on microzooplankton and trait-based approaches to zooplankton communities.
Six papers then describe novel molecular methods for investigating zooplankton feeding and digestion rates, zooplankton diets and predator-prey interactions. Innovative approaches involving the use of gut fluorescence and in vivo fluorometry are then considered followed by papers that describe new approaches involving using a variety of tracers. These include fluorescent microparticles, fatty acids, pigment analysis and stable isotopes.
The collection concludes with two recent JPR papers on the dilution technique, which remains one of the key methods for estimating microzooplankton community grazing.
