Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Quantitative analysis of amino acid excretion by Methanothermobacter marburgensis under N2-fixing conditions

Scientific Reports
Methanogenic archaea (methanogens) possess fascinating metabolic characteristics, such as the ability to fix molecular nitrogen (N2). Methanogens are of biotechnological importance due to the ability to produce methane (CH4) from molecular hydrogen (H2 ...

CrustCheck: a conceptual framework for interpreting biocrust trait–function relationships in drylands

Restoration Ecology, EarlyView.
Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Structure and specificity of novel aminopeptidase from marine sediment Archaea [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
The Earth's microbial diversity remained largely unexplored until recent developments in DNA sequencing. Novel methods enabled us to access genomic information of uncultured microbial organisms and create hypotheses about their metabolic capabilities. These predictions primarily rely on the sequence similarity between a novel protein and characterized ...

Simulation of Enhanced Growth of Marine Group II Euryarchaeota From the Deep Chlorophyll Maximum of the Western Pacific Ocean: Implication for Upwelling Impact on Microbial Functions in the Photic Zone

Frontiers in Microbiology, 2020
Mesoscale eddies can have a strong impact on regional biogeochemistry and primary productivity. To investigate the effect of the upwelling of seawater by western Pacific eddies on the composition of the active planktonic marine archaeal community ...

Gastrointestinal microbiota and barrier integrity in individuals who develop exertional heat illness and pair‐matched controls: A prospective observational cohort study

Experimental Physiology, EarlyView.
Abstract It has been hypothesised that the composition of the gastrointestinal (GI) microbiota contributes to exertional heat illness (EHI) aetiology, but relevant empirical data in humans are lacking. Utilising a unique prospective study design, stool samples and resting blood samples were obtained from 550 individuals prior to (within 3 days ...

Flexible TAM requirement of TnpB enables efficient single-nucleotide editing with expanded targeting scope

Nature Communications
TnpBs encoded by the IS200/IS605 family transposon are among the most abundant prokaryotic proteins from which type V CRISPR-Cas nucleases may have evolved.

Archaeal Sources of Intact Membrane Lipid Biomarkers in the Oxygen Deficient Zone of the Eastern Tropical South Pacific

Frontiers in Microbiology, 2019
Archaea are ubiquitous in the modern ocean where they are involved in the carbon and nitrogen biogeochemical cycles. However, the majority of Archaea remain uncultured.

Resistance of Botrytis cinerea to anilinopyrimidine fungicides: A novel ARMS‐PCR method for the detection of Bcpos5 mutations and characterization of resistance using CRISPR/Cas9 editing

Pest Management Science, Volume 82, Issue 9, Page 8189-8198, September 2026.
A TETRA‐primer amplification refractory mutation system polymerase chain reaction (T‐ARMS‐PCR) method was developed for simultaneous detection of the L412F/V and G408V mutations. L412F/V mutants were created using the CRISPR/Cas tool and no fitness cost was observed.

First archaeal rDNA sequences from Argentine coastal waters: Unexpected PCR characterization using eukaryotic primers

Ciencias Marinas, 2012
Many members of Archaea, a group of prokaryotes recognized three decades ago, colonize extreme environments; however, new research has shown that Archaeans are also abundant components of plankton in the open sea, where they play a key role in the ...
