The past 100 years of ecological research has seen substantial progress in understanding
the natural world and likely effects of change, whether natural or anthropogenic. Traditional …

SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated
population size of 2.4× 1028 cells—approximately 25% of all plankton. They are found …

Current sampling of genomic sequence data from eukaryotes is relatively poor, biased, and
inadequate to address important questions about their biology, evolution, and ecology; this …

Technological advances are enabling the sequencing of environmental DNA and RNA at
increasing depth and with decreasing costs. Metagenomic and transcriptomic analysis of …

Community dynamics are central in microbial ecology, yet we lack studies comparing
diversity patterns among marine protists and prokaryotes over depth and multiple years …

Pelagic microbes have adopted distinct strategies to inhabit the pelagial of lakes and
oceans and can be broadly categorized in two groups: free‐living, specialized oligotrophs …

The oceanic waters below a depth of 200 m represent, in terms of volume, the largest habitat
of the biosphere, harboring approximately 70% of the prokaryotic biomass in the oceanic …

Deep-ocean regions beyond the reach of sunlight contain an estimated 615 Pg of dissolved
organic matter (DOM), much of which persists for thousands of years. It is thought that …

Bacteria of the SAR11 clade constitute up to one half of all microbial cells in the oxygen-rich
surface ocean. SAR11 bacteria are also abundant in oxygen minimum zones (OMZs), where …

With rapidly improving sequencing technologies, scientists have recently gained the ability
to examine diverse microbial communities at high genomic resolution, revealing that both …
