Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Probe Capture Enrichment Sequencing of amoA Genes Improves the Detection of Diverse Ammonia‐Oxidising Archaeal and Bacterial Populations

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.
ABSTRACT The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia‐oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces

PMOA-TTS: Introducing the PubMed Open Access Textual Times Series Corpus

Understanding temporal dynamics in clinical narratives is essential for modeling patient trajectories, yet large-scale temporally annotated resources remain limited. We present PMOA-TTS, the first openly available dataset of 124,699 PubMed Open Access (PMOA) case reports, each converted into structured (event, time) timelines via a scalable LLM-based ...

Targeted DNA demethylation of the Arabidopsis genome using the human TET1 catalytic domain. [PDF]

, 2018
DNA methylation is an important epigenetic modification involved in gene regulation and transposable element silencing. Changes in DNA methylation can be heritable and, thus, can lead to the formation of stable epialleles. A well-characterized example of

Global peatland greenhouse gas dynamics: state of the art, processes, and perspectives

New Phytologist, Volume 246, Issue 1, Page 94-102, April 2025.
Summary Natural peatlands regulate greenhouse gas (GHG) fluxes through a permanently high groundwater table, causing carbon dioxide (CO2) assimilation but methane (CH4) emissions due to anaerobic conditions. By contrast, drained and disturbed peatlands are hotspots for CO2 and nitrous oxide (N2O) emissions, while CH4 release is low but high from ...

A Functional Ecological Comparison of three Sponge Species from the Lower Florida Keys [PDF]

, 2017
The shallow, tidal flats off the islands of the lower Florida Keys represent a harsh environment for sessile marine invertebrates. This habitat is home to three taxonomically distinct sponge species that share similar rope morphologies: Cliona varians ...

Abrupt Changes in the Timing and Magnitude of the North Atlantic Bloom Over the 21st Century

Journal of Geophysical Research: Oceans, Volume 130, Issue 3, March 2025.
Abstract The North Atlantic subpolar gyre (SPG) is a key region for the North Atlantic bloom (NAB), the phytoplankton foundation of the regional food web. The NAB depends on nutrients seasonally introduced into the surface ocean by deep winter convection.

Nitric Oxide Dismutase (nod) Genes as a Functional Marker for the Diversity and Phylogeny of Methane-Driven Oxygenic Denitrifiers

Frontiers in Microbiology, 2019
Oxygenic denitrification represents a new route in reductive nitrogen turnover which differs from canonical denitrification in how nitric oxide (NO) is transformed into dinitrogen gas.

Response of methanotrophic activity and community structure to temperature changes in a diffusive CH4/O2 counter gradient in an unsaturated porous medium [PDF]

, 2017
Microbial methane oxidation is a key process in the global methane cycle. In the context of global warming, it is important to understand the responses of the methane-oxidizing microbial community to temperature changes in terms of community structure ...

Biochar-based urea increases soil methane uptake in a subtropical forest

Geoderma
Novel biochar-based fertilizers, produced by combining biochar particles with chemical fertilizers, have strong potential to enrich soil with carbon (C) and nitrogen (N), and to increase plant productivity.
