TL;DR: The relative contribution of gene expression changes to be significantly lower in polar than in non-polar waters and it is hypothesized that in polar regions, alterations in community activity in response to ocean warming will be driven more strongly by changes in organismal composition than by gene regulatory mechanisms.

TL;DR: This work investigates the latitudinal gradients and global predictors of plankton diversity across archaea, bacteria, eukaryotes, and major virus clades using both molecular and imaging data from Tara Oceans to show a decline of diversity for most planktonic groups toward the poles.

TL;DR: A review on the technologies available to make globally quantitative observations of particles, in general, and plankton, in particular, in the world oceans, and for sizes varying from sub-micron to centimeters is presented in this article.

TL;DR: It is shown that a substantial part of the biomass of plankton larger than 600 μm consists of giant protists belonging to the Rhizaria, a super-group of mostly fragile unicellular marine organisms that includes the taxa Phaeodaria and Radiolaria

TL;DR: In this article, a model was proposed to describe the midwater particle population by its mass distribution for the size range 1-μm to 1-cm, and the combination of this model with a unique particle size spectra data set, obtained during an interannual survey at the French JGOFS site in the NW Mediterranean Sea, gave an insight into the key processes for particle dynamics in the unknown midwater layers.
