Oxygenic photosynthesis supplies organic carbon to the modern biosphere, but it is
uncertain when this metabolism originated. It has previously been proposed, that …

The terrestrial deep subsurface is a huge repository of microbial biomass, but in relation to
its size and physical heterogeneity, few sites have been investigated in detail. Here, we …

Parrotfish are key agents of bioerosion and sediment production in coral reef ecosystems;
however, their dietary targets and therefore potential sources of variation in carbonate …

Diet in fish is influenced by multiple factors including nutritional requirements, trophic
morphology and spatial and temporal variation in resource availability. We examined spatial …

Trichodesmium is a genus of marine diazotrophic colonial cyanobacteria that exerts a
profound influence on global biogeochemistry, by injecting 'new'nitrogen into the low …

Earth's deep subsurface biosphere (DSB) is home to a vast number and wide variety of
microorganisms. Although difficult to access and sample, deep subsurface environments …

Nitrogen‐fixing cyanobacteria in the genus Trichodesmium play a critical role in the
productivity of the tropical and subtropical oligotrophic oceans. The ecological success of …

In oligotrophic ocean regions such as the North Pacific Subtropical Gyre (NPSG), N2 fixation
(ie, diazotrophy) by a diverse consortium of microorganisms has been shown to contribute …

Trichodesmium spp. are diazotrophic cyanobacteria that exist as single filaments (trichomes)
and as macroscopic colonies of varying shapes formed by aggregating trichomes. The …

The biological carbon pump (BCP) in the Southern Ocean is driven by phytoplankton
productivity and is a significant organic matter sink. However, the role of particle-attached …
