Sentences with word «picoplankton»

Major consequences of such changes over regional scales will probably include (1) reductions in primary production combined with (2) shifts from diatom - dominated (low SA: V ratio) phytoplankton assemblages with high POC - export efficiencies to picoplankton communities (high SA: V ratio) characterized by low export efficiencies (Smith et al., 2008; Morán et al., 2010; Morán et al., 2015).

Researchers say that there is an urgent need to uncover how specific coral picoplankton interactions contribute to these threatened ecosystems.

In novel lab observations of interactions between corals and planktonic bacteria, known as picoplankton, researchers found that corals are selectively feeding on specific types of bacteria — the same bacteria whose growth is promoted by organic matter and nutrients that are released by the corals.

We analysed these sequences, along with previously published marine prokaryotic genomes, in the context of marine metagenomic data, to gain insights into the ecology of the surface ocean prokaryotic picoplankton (0.1 - 3.0 μm size range).

We recently developed a new SST proxy (the TEX86) based on the relative distribution of tetraether membrane lipids derived from marine Crenarchaeota, a ubiquitous and omnipresent component of marine picoplankton.

Variation in plastic responses of a globally distributed picoplankton species to ocean acidification

«This study shows that corals do in fact influence the picoplankton community by selecting specific lineages of picoplankton for removal and also by potentially using the complex carbon compounds excreted by the coral to promote the growth of these lineages,» adds Rachel Parsons, a microbial oceanographer at BIOS and coauthor of the paper.
