Metagenomics of the deep Mediterranean, a warm bathypelagic habitat.
BackgroundMetagenomics is emerging as a powerful method to study the function and physiology of the unexplored microbial biosphere, and is causing us to re-evaluate basic precepts of microbial ecology and evolution.

Barcoding Atlantic Canada's mesopelagic and upper bathypelagic marine fishes.
DNA barcode sequences were developed from 557 mesopelagic and upper bathypelagic teleost specimens collected in waters off Atlantic Canada. Confident morphological identifications were available for 366 specimens, of 118 species and 93 genera, which ...

Gradients of bacteria in the oceanic water column reveal finely-resolved vertical distributions. [PDF]
Bacterial communities directly influence ecological processes in the ocean, and depth has a major influence due to the changeover in primary energy sources between the sunlit photic zone and dark ocean.

The Open-Ocean Gulf of Mexico After Deepwater Horizon: Synthesis of a Decade of Research
The scale of the Deepwater Horizon disaster was and is unprecedented: geographic extent, pollutant amount, countermeasure scope, and of most relevance to this Research Topic issue, range of ecotypes affected.

Depth-related patterns in microbial community responses to complex organic matter in the western North Atlantic Ocean [PDF]
Oceanic bacterial communities process a major fraction of marine organic carbon. A substantial portion of this carbon transformation occurs in the mesopelagic zone, and a further fraction fuels bacteria in the bathypelagic zone. However, the capabilities

Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach. [PDF]
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Too Close for Comfort? Isotopic Niche Segregation in New Zealand’s Odontocetes
Species occurring in sympatry and relying on similar and limited resources may partition resource use to avoid overlap and interspecific competition.
