Synchronization in large directed networks of coupled phase oscillators

, 2005
We extend recent theoretical approximations describing the transition to synchronization in large undirected networks of coupled phase oscillators to the case of directed networks.

Artificial electron acceptors decouple archaeal methane oxidation from sulfate reduction [PDF]

, 2016
The oxidation of methane with sulfate is an important microbial metabolism in the global carbon cycle. In marine methane seeps, this process is mediated by consortia of anaerobic methanotrophic archaea (ANME) that live in syntrophy with sulfate-reducing ...

Genome‐Resolved Approach of Guerrero Negro Hypersaline Microbial Mats Reveals the Metabolic Potential of Key Players in a Stratified Community

Environmental Microbiology, Volume 27, Issue 11, November 2025.
The first metagenome‐assembled genomes (MAGs) from Guerrero Negro hypersaline microbial mats were recovered from natural and incubated samples. These MAGs include dominant and rare taxa, whose metabolic potential provides clues to metabolic versatility in the cycling of three elements (carbon, sulfur, and nitrogen) at the genome and community levels ...

Methane-related changes in prokaryotes along geochemical profiles in sediments of Lake Kinneret (Israel) [PDF]

Biogeosciences, 2015
Microbial methane oxidation is the primary control on the emission of the greenhouse gas methane into the atmosphere. In terrestrial environments, aerobic methanotrophic bacteria are largely responsible for this process.

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]

, 2007
The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

Geriatric Nutritional Risk Index and In‐Hospital Mortality and Costs in Older Inpatients With and Without Cancer: A Retrospective Observational Study

Journal of Clinical Nursing, Volume 34, Issue 11, Page 4630-4641, November 2025.
ABSTRACT Aims To explore the association of the Geriatric Nutritional Risk Index (GNRI) with in‐hospital mortality and costs in older inpatients and to compare these associations between cancer and non‐cancer patients to inform clinical practice. Design Retrospective observational study.

Chemosynthetic Organic Matter Reveals a Protracted Episode of Past Methane Seepage Activities at a Newly Discovered Cold Seep Site (Mannar Basin) Off the East Coast of India

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Here, we present organic geochemical evidence of past methane‐seepage events in a sediment core retrieved from a recently discovered methane cold‐seep site off Mannar Basin, east coast of India. The significant negative C‐isotope excursion of organic matter (δ13CTOC) in the seep core compared to a reference non‐seep core suggests a substantial

Metabolic capabilities of microorganisms involved in and associated with the anaerobic oxidation of methane

Frontiers in Microbiology, 2016
In marine sediments the anaerobic oxidation of methane with sulfate as electron acceptor (AOM) is responsible for the removal of a major part of the greenhouse gas methane.

Sulfur Isotope Biogeochemistry Controlled by Sulfate Reduction Activity in Cold Seep Sediments

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Cold seeps are unique deep‐sea ecosystems that play an important role in marine biogeochemical cycles. However, the dynamics and regulation of sulfur isotope biogeochemistry in seep sediments remain unconstrained. We investigated the geochemical characteristics of active seep sites, including the content and stable isotope composition of ...
