TL;DR: It is argued that carefully estimated faecal volume production provides a simple and quick overall feeding estimate with important advantages over the common gut pigment technique, and it may be used as an inde- pendent method in bottle incubation experiments.

TL;DR: Results of systematic efforts to develop a quantitative PCR (qPCR) assay targeted to 18S rRNA gene fragments to estimate copepod gut content of specific species of prey algae demonstrate a semi-quantitative relationship between gut content estimates derived from qPCR, gut pigment, and direct microscopy.

TL;DR: The principal goal of the present study was searching for a generally applicable or methodology-dependent converting factor for the bacterial biomass calculation, which suggested a relationship generalized for different methods of carbon and cell volume recalculations and applicable for bacterial cells larger than 0.025 μm3.

TL;DR: The development of mass balance and proportion of heterotrophic/autotrophic biomass predict a shift towards a more autotrophic community and less-efficient food web transfer when temperature, nutrients and acidification are combined in a future climate-change scenario.

TL;DR: It is suggested that diatoms utilize Phaeocystis colonies not only as habitat, but that they are able to utilize the colonial matrix as a growth substrate.
