The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]

open access: yes, 1987
The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

Disentangling the counteracting effects of water content and carbon mass on zooplankton growth [PDF]

open access: yes, 2016
Zooplankton vary widely in carbon percentage (carbon mass as a percentage of wet mass), but are often described as either gelatinous or non-gelatinous. Here we update datasets of carbon percentage and growth rate to investigate whether carbon percentage ...

Investigating Environmental DNA Variability and Species Detections Through Passive and Active Sampling Across Time: A Case Study From a Hyper‐Diverse Coastal System

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This study compared the ability of active and passive eDNA filtration methods to capture environmental DNA in a marine environment with highly variable eDNA signals. Active sampling detected a greater proportion of fish biodiversity, whereas passive sampling detected a larger proportion of metazoa, with a trend of significant accumulation of numbers of

Never ending analysis of a century old evolutionary debate: unringing the urmetazoon bell

open access: yesFrontiers in Ecology and Evolution, 2016
Our understanding of the early evolution of animals will be greatly improved if a final solution can be found to the evolutionary relationships between Porifera, Placozoa, Ctenophora, Cnidaria and Bilateria.

MetaZooGene Intercalibration Experiment (MZG‐ICE): Metabarcoding Marine Zooplankton Diversity of the Global Ocean

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT DNA metabarcoding of zooplankton biodiversity is used increasingly for monitoring global ocean ecosystems, requiring comparable data from different research laboratories and ocean regions. The MetaZooGene Intercalibration Experiment (MZG‐ICE) was designed to examine1 and analyse patterns of variation of DNA sequence data resulting from multi ...

A study on the biodiversity of benthic invertebrates in the waters of Seogwipo, Jeju Island, Korea

open access: yesJournal of Asia-Pacific Biodiversity, 2014
The biodiversity of benthic invertebrates in the intertidal and subtidal regions of Gapado, Beomseom, and Munseom islets was surveyed twice in May and September 2013 to study the state of biodiversity in Seogwipo, Jeju Island.

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

open access: yesEvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.
