Non‐Invasive Underwater DNA Sampling Illuminates Red Sea Echinoderm Diversity
Molecular Ecology Resources, Volume 26, Issue 1, January 2026.ABSTRACT Species‐specific non‐invasive underwater DNA sampling remains largely understudied for marine invertebrates despite its potential to revolutionise biodiversity assessment of vulnerable species or fragile ecosystems. Comprehensive species‐specific DNA barcode databases are essential for accurate species identification and taxonomic assignment ...

Prey Resource Utilization by Coexistent Hydromedusae from Friday Harbor, Washington, USA [PDF]
, 2002 Prey selection patterns were quantified for a sympatric group of hydromedusae from Friday Harbor, WA. Selection patterns varied between species, but were largely replicable between sample dates and resembled dietary patterns found in similar studies from

Seasonal Dynamics and Stability of Zooplankton Community in Mytilus coruscus Farming Areas
Aquaculture Research, Volume 2026, Issue 1, 2026.Large‐scale mussel farming affects marine plankton, yet the seasonal dynamics and stability of zooplankton community in mussel farms remain poorly understood. To evaluate the seasonal variation of zooplankton community and potential aquaculture impacts, surveys on zooplankton community in mussel farms near Gouqi Island were carried out in October 2022 (

Density regulation inSarsia tubulosa (Hydrozoa) [PDF]
Helgoländer Meeresuntersuchungen, 1980 The majority of wild-caughtSarsia tubulosa M. Sars medusae are less dense than the surrounding water. The bell ofS. tubulosa is the buoyant structure; the tentacles and manubrium sink if cut off from the bell.S. tubulosa individuals placed in dilute seawater sink initially but recover positive or neutral buoyancy and normal activity within a couple of ...

Living on the edge: Biofilms developing in oscillating environmental conditions [PDF]
, 2019 For the first time, the densities and diversity of microorganisms developed on ocean gliders were investigated using flow cytometry and Illumina MiSeq sequencing of 16S and 18S rRNA genes. Ocean gliders are autonomous buoyancy-driven underwater vehicles,

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.Alentiana, a genus within the subfamily Lepidastheniinae of Polynoidae, is an obligately commensal deep‐sea group exclusively associated with sea anemones. Currently, only two valid species are recognized, with the genus’s species diversity and phylogenetic relationships remaining poorly understood.

Ecology and Evolution, Volume 15, Issue 12, December 2025.To assess whether hydroids (Cnidaria, Hydrozoa) are good candidates to test the Deep Reef Refuge Hypothesis and particularly the vertical connectivity component, we analysed the genetic diversity and structure of seven species sampled across euphotic and mesophotic depths around Mayotte and Reunion in the southwestern Indian Ocean.

The Hydrozoa: a new classification in the light of old knowledge [PDF]
, 2000 The Hydrozoa, on the basis of embryological, developmental and morphological features, are considered as a superclass of the phylum Cnidaria comprising three classes: the Automedusa (with the subclasses: Actinulidae, Narcomedusae and Trachymedusae ...
