An ecological trade-off between growth and death enables microbes with different dispersal strategies to coexist on particulate matter in the oceans.

Three-dimensional fluorescence imaging of microbial eukaryotes in environmental samples allows accurate automated taxonomic profiling and quantitative data about ultrastructures and interactions of organisms.

Interest in the ecology, biology and evolution of amphioxus is growing, and the availability of several species is helping to improve our understanding of chordate evolution.

A genome analysis of Xenoturbella bocki provides insights into the biology of this enigmatic marine worm and enhances our understanding of early bilaterian evolution.

Coral symbiotic alga is capable of degrading the own cell wall components by cellulase-related enzymes and releasing sugars as a simple and autonomous environmental response, even when the host-derived signals are not present.

Phylogenomics reveals the timeline over which marine bacteria and archaea colonized the oceans and shows the geological context of their diversification.

One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

The combination of holographic microscopy and deep learning provides a revolutionary tool for plankton ecology that will permit researchers to observe and study the life, feeding habits and reproduction of plankton with unprecedented detail.

Mutualistic viruses called virophages are common genome inhabitants of a marine protist, where they may protect host populations from giant viruses.
