Morphology and distribution of a deep-water Narcomedusa (Solmarisidae) from the northeast Pacific

open access: yesScientia Marina, 2000
Specimens of Solmaris sp. (Solmarisidae, Narcomedusae) with only four tentacles were collected in the northeast Pacific. The majority were collected in Canadian Pacific waters by Tucker trawl from stations outside the 500-m contour off the west coast of ...

Biogeographical distribution of the benthic thecate hydroids collected during the Spanish Antartida 8611 expedition and comparison between Antarctic and Magellan benthic hydroid faunas

open access: yesScientia Marina, 1999
The biogeographical distribution of the benthic hydroid species collected during the Spanish Antarctic expedition Antártida 8611 has been studied. An inventory of the Antarctic and Magellan benthic thecate hydroid faunas, along with a comparison between ...

An endogenous green fluorescent protein–photoprotein pair in Clytia hemisphaerica eggs shows co-targeting to mitochondria and efficient bioluminescence energy transfer [PDF]

open access: yesOpen Biology, 2014
Green fluorescent proteins (GFPs) and calcium-activated photoproteins of the aequorin/clytin family, now widely used as research tools, were originally isolated from the hydrozoan jellyfish Aequora victoria.

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

An evolutionary genomics view on neuropeptide genes in Hydrozoa and Endocnidozoa (Myxozoa)

open access: yesBMC Genomics, 2021
Background The animal phylum Cnidaria consists of six classes or subphyla: Hydrozoa, Scyphozoa, Cubozoa, Staurozoa, Anthozoa, and Endocnidozoa. Cnidarians have an early evolutionary origin, diverging before the emergence of the Bilateria.

A Modified Gear Removal Index (GRI) Method to Support the Management of Abandoned Fishing Gear on Coralligenous Reefs

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Abandoned, Lost or otherwise Discarded Fishing Gears (ALDFG) have significant negative effects on marine ecosystems. In the Mediterranean Sea, the impact of ALDFG is particularly relevant on coralligenous reefs. The management of ALDFG focuses primarily on their removal, however this type of intervention may potentially damage the habitat, so ...

Surveying Biodiverse Coral Reef Ecosystems Across the Tree of Life With Environmental DNA

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT A central challenge in evaluating biodiversity using environmental DNA (eDNA) metabarcoding is that each primer set has biases resulting in selective amplification of taxonomic diversity. Here we test 11 primer pairs to assess Central Pacific coral reef diversity in the five kingdoms of marine eukaryotes: Chromista, Fungi, Metazoa, Plantae and
