DNA Metabarcoding of Deep-Sea Sediment Communities Using COI: Community Assessment, Spatio-Temporal Patterns and Comparison with 18S rDNA

Diversity, 2020
Among the complex ecosystems and habitats that form the deep sea, submarine canyons and open slope systems are regarded as potential hotspots of biodiversity.

Fine‐Scale Ecological Biomonitoring in a Large, Complex Agriculturally Impacted Watershed via eDNA Metabarcoding

Molecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT DNA‐based approaches utilizing high‐throughput sequencing (HTS) (e.g., DNA metabarcoding) have revolutionized ecological biomonitoring by providing higher sample throughput, greater reproducibility, and better cost‐benefits compared to traditional morphology‐based bioassessment studies.

Molecular Phylogeny, Species Delimitation, and Biogeography of the Varunid Crab Genus Metaplax (Crustacea, Varunidae)

Zoologica Scripta, Volume 55, Issue 3, Page 504-518, May 2026.
ABSTRACT The Indo‐West Pacific genus Metaplax comprises 11 recognised species inhabiting intertidal mudflats, some adjacent to mangroves. To resolve long‐standing uncertainties, we analysed mitochondrial (COI, 16S) and nuclear (28S) markers. Phylogenetic analyses recovered Metaplax as monophyletic and resolved four well‐supported clades—the M ...

Swabbing as a Non‐Lethal DNA Collection Method for Earthworm Barcoding: Performance and Citizen Science Perspectives

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Earthworm DNA barcoding commonly relies on lethal tissue sampling, which can discourage participation in citizen science projects due to emotional concerns. By comparing swab‐based and tissue‐based DNA collection methods, we show that swab sampling represents a promising, participant‐friendly option for citizen science–based earthworm biodiversity ...

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 ...

The enigmatic case of Lipoptena sp. in the Bosco della Mesola Nature Reserve (Italy)

Medical and Veterinary Entomology, Volume 40, Issue 1, Page 82-90, March 2026.
This is the first report of Lipoptena andaluciensis in Italy, confirmed morphologically and genetically. The presence of L. andaluciensis in Italy dates back many years; it was found on cervids in lowland habitats. A re‐examination of the previous report of the Italian L. fortisetosa is needed.

A Comparative Analysis of DNA Metabarcoding and Morphological Identification in Diatoms Reveals Similar Patterns of Environmental Response

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study compares the use of two universal molecular markers (COI and 18S rRNA) with morphological identification to evaluate patterns in diatom communities from high mountain mires. The results revealed a strong correspondence in beta diversity and environmental response across beta and alpha diversity. However, these molecular markers were found to

Genetic Diversity, Population Structure and Differentiation of Farmed and Wild African Catfish (Clarias gariepinus) in Nigeria

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT The African catfish (Clarias gariepinus) is a commercially important species, for both fisheries and aquaculture, and is now the most commonly farmed fish in sub‐Saharan Africa. However, knowledge about the genetic diversity and population structure of natural and farmed populations, which is crucial for effective conservation and sustainable ...

Hybrid warfare on the Ukrainian battlefield: developing theory based on empirical evidence

Journal on Baltic Security, 2019
With the takeover of Crimea by masked Russian soldiers/fighters without national insignia in February/March 2014, with the Kremlin at first denying its involvement, war became ‘hybrid’ in our minds.
