Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

The profound influence of microorganisms on human life and global biogeochemical cycles
underlines the value of studying the biogeography of microorganisms, exploring microbial …

Revealing the biogeographies and ecologies of rare and abundant microorganisms is
crucial to understand ecosystem diversity and function. In this study, we investigated the …

Impacts of global climate change on terrestrial ecosystems are imperfectly constrained by
ecosystem models and direct observations. Pervasive ecosystem transformations occurred …

Marine microbial communities are engines of globally important processes, such as the
marine carbon, nitrogen and sulphur cycles. Recent data on the structures of these …

The way that nutrients cycle through atmospheric, terrestrial, oceanic and associated biotic
reservoirs can constrain rates of biological production and help structure ecosystems on …

Biological N2 fixation is an important part of the marine nitrogen cycle as it provides a source
of new nitrogen that can support biological carbon export and sequestration. Research in …

The ocean's nitrogen cycle is driven by complex microbial transformations, including
nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the …

Discrepancies between estimates of oceanic N 2 fixation and nitrogen (N) losses through
denitrification have focused research on identifying N 2-fixing cyanobacteria and quantifying …

Many multicellular cyanobacteria produce specialized nitrogen-fixing heterocysts. During
diazotrophic growth of the model organism Anabaena (Nostoc) sp. strain PCC 7120, a …
