Microbial Community Structure of Subglacial Lake Whillans, West Antarctica

Frontiers in Microbiology, 2016
Subglacial Lake Whillans (SLW), located beneath ~800 m of ice on the Whillans Ice Stream in West Antarctica was sampled in January of 2013, providing the first opportunity to directly examine water and sediments from an Antarctic subglacial lake.

Genomic inference of the metabolism of cosmopolitan subsurface Archaea, Hadesarchaea

Nature Microbiology, 2016
The subsurface biosphere is largely unexplored and contains a broad diversity of uncultured microbes1. Despite being one of the few prokaryotic lineages that is cosmopolitan in both the terrestrial and marine subsurface2–4, the physiological and ...

Is the Hyporheic Zone Relevant beyond the Scientific Community? [PDF]

, 2019
Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along the river network. We elaborate on the main physical, biological,

Low Energy Subsurface Environments as Extraterrestrial Analogs

Frontiers in Microbiology, 2018
Earth’s subsurface is often isolated from phototrophic energy sources and characterized by chemotrophic modes of life. These environments are often oligotrophic and limited in electron donors or electron acceptors, and include continental crust ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Genomic Description of ‘Candidatus Abyssubacteria,’ a Novel Subsurface Lineage Within the Candidate Phylum Hydrogenedentes

Frontiers in Microbiology, 2018
The subsurface biosphere is a massive repository of fixed carbon, harboring approximately 90% of Earth’s microbial biomass. These microbial communities drive transformations central to Earth’s biogeochemical cycles. However, there is still much we do not

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
