The effect of estuarine system on the meiofauna and nematodes in the East Siberian Sea

Scientific Reports, 2021
Arctic meiofauna and nematodes were examined at 12 stations in the East Siberian Sea, covering a depth range of 13–59 m and an estuarine-shelf system from the Indigirka and Kolyma rivers to the adjacent shelf.

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

The Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

Meiofauna Community in Soft Sediments at TAG and Snake Pit Hydrothermal Vent Fields

Frontiers in Marine Science, 2020
The risk assessment of seafloor massive sulfide (SMS) mining on meiobenthic organisms, specifically on soft-sediment meiofauna, is impeded by a lack of knowledge on the biology and ecology of these communities.

Performance and Limitations of Out‐Of‐Distribution Detection for Insect DNA Barcoding

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Benchmarking shows that detecting unknown species is more difficult than identifying known species with short DNA barcoding. ABSTRACT Successful applications of DNA barcoding rely on the accurate taxonomic identification of sequence fragments. When biological surveys with DNA barcoding target underexplored biological communities, sequence‐based ...

CellTracker Green labelling vs. rose bengal staining: CTG wins by points in distinguishing living from dead anoxia-impacted copepods and nematodes [PDF]

Biogeosciences, 2013
Hypoxia and anoxia have become a key threat to shallow coastal seas. Much is known about their impact on macrofauna, less on meiofauna. In an attempt to shed more light on the latter group, in particular from a process-oriented view, we experimentally ...

Cryptofauna Associated With the Epilithic Algal Matrix on Subtropical Brazilian Reefs

Austral Ecology, Volume 51, Issue 2, February 2026.
ABSTRACT The epilithic algal matrix (EAM) plays a significant role in the benthic cover of reefs worldwide. In Brazil, the EAM accounts for a substantial proportion of the benthos, and its associated fauna contributes to the majority of the reef's metazoan biodiversity and is an important link into the trophic chain, connecting the production performed

Improved taxonomic and gene sampling advance the knowledge of deep relationships within Macrodasyida (Gastrotricha)

Cladistics, Volume 42, Issue 1, Page 25-45, February 2026.
Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.

Ichnological insights into deoxygenation across the Cenomanian–Turonian Boundary Oceanic Anoxic Event 2 in the northern extent of Western Interior Seaway (west‐central Alberta)

Sedimentology, Volume 73, Issue 2, Page 355-390, February 2026.
ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...

Problems in meiofauna energy-flow studies [PDF]

Hydrobiologia, 1984
The direct estimation of energy flow through marine meiobenthic populations poses several difficulties, mainly relating to sampling problems. The usefulness of some indirect estimation methods is discussed.
