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

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 ...

New genomic data and analyses challenge the traditional vision of animal epithelium evolution

open access: yesBMC Genomics, 2018
Background The emergence of epithelia was the foundation of metazoan expansion. Epithelial tissues are a hallmark of metazoans deeply rooted in the evolution of their complex developmental morphogenesis processes.

First records of two lobate comb-jellies (Ctenophora) from the Pakistani coast [PDF]

open access: yesCheck List, 2015
The knowledge on the comb-jellies faunistics along the southern Asian coast is very scarce. For some countries such as Pakistan there are no previous formal records of ctenophores. This study is a first survey to the group diversity along Pakistani coast,

Is the Presence of Jellyfish Problematic or Beneficial?

open access: yesWalailak Journal of Science and Technology, 2013
Jellyfish are a diverse group of animals. The group consists of Chordata, Ctenophora and, mainly, Cnidaria. Jellyfish are often thought to be harmful, but few can cause fatality in humans.

Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3634-3649, December 2025.
Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

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.
