Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Abundance of Meiofauna and Physical-Chemical Parameters as Water Quality Indicator

Ilmu Kelautan, 2019
The zone of Losari Coast is an icon of Makassar city, however increase activity of surrounding communities causes a decrease in the water quality. Meiofauna is an effective benthic organism used as an indicator of water quality.

Meiofauna Biodiversity and Community Structures in the Barents Sea and Nansen Basin Are Influenced by Benthic Spatiotemporal Heterogeneity

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Benthic meiofauna in the Barents Sea were investigated for spatiotemporal variability and taxonomic composition. ABSTRACT Meiobenthic metazoans occur worldwide and are a cornerstone of aquatic ecosystems. Here, we investigate the composition of meiobenthic communities along a transect in the Barents Sea and Nansen Basin and provide the first ...

Meiofauna in Tropical Montane Streams: Biotic and Abiotic Factors Regulating Communities

Acta Biológica Colombiana, 2023
Meiofauna is a group of heterotrophic organisms smaller than macroinvertebrates but larger than microfauna and characterized by groups such as testate amoebae, ciliates, and nematodes.

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Environmental Gradients, Not Geographic Boundaries, Structure Meiofaunal Communities in Siberian Seas

Environmental DNA
Meiofauna (all invertebrates smaller than 1 mm) are not only sensitive to environmental changes but also contribute significantly to nutrient cycling and energy transfer to higher trophic levels.

Differentiating hyperpycnal, hypopycnal and turbidity current deposits in late Quaternary glaciogenic mud

The Depositional Record, Volume 12, Issue 1, February 2026.
X‐ray CT and microscopic analysis of glaciogenic mud provide insight into the deposits of sediment‐laden density flows and reveal that strata comprise two microtextural motifs. The deposits of bottom‐hugging hyperpycnal flows and slope‐failure‐related turbidity currents are characterised by laterally continuous, sharply bounded silt‐rich and clay‐rich ...

Taking machine learning with a grain of sand: Sediment Analysis Neural‐network Data‐engine (SAND‐e) reveals sedimentological differences between turbid and clear‐water reefs

The Depositional Record, Volume 12, Issue 1, February 2026.
Using machine learning, researchers can count and crudely identify sand grains from coral reefs automatically. This will allow us to generate larger datasets to answer sedimentological questions. Abstract Sediment is an important facet of sand cay reefs as it is responsible for reef accretion and island formation, with shifts in the proportions of ...
