Small jellyfish, large consequences: The overlooked predatory role of hydromedusae in subtropical estuarine ecosystems

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Hydromedusae are often overlooked in pelagic trophic ecology compared to large scyphozoans. We investigated the diet, prey selectivity, ingestion rates, digestion times, and predation impacts of the native Liriope tetraphylla and non‐indigenous species Cnidostoma fallax and Moerisia inkermanica in a subtropical estuary of the southwestern ...

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

Fish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.

First record of the association between Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) and Cyrtograpsus affinis (Decapoda, Varunidae) Primer registro de la asociación entre Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) y Cyrtograpsus affinis (Decapoda, Varunidae)

Latin American Journal of Aquatic Research, 2012
We report the association between the jellyfish Lychnorhiza lucerna and the crab Cyrtograpsus affinis. Numerous examples of associations between medusae and brachyurans have been observed in the field and noted in the literature.

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

BMC 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.

Effects of experimental in situ seabed disturbance on deep‐sea macrofaunal communities of Chatham Rise, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1422-1459, December 2025.
ABSTRACT With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood.

Coupling hydrodynamic drifting simulations and seasonal demographics to unmask the drivers of jellyfish blooms

Journal of Applied Ecology, Volume 62, Issue 11, Page 2971-2986, November 2025.
Crucially, the framework we present here offers an approach for identifying the, to date, unknown locations of polyp beds; a key parameter in enhancing our capacity to accurately predict the occurrence of jellyfish blooms. Accordingly, this framework represents a key decision‐support tool for mitigating the socio‐economic impacts of bloom formation ...

Cytotoxic effect on human keratinocytes of crude extracts from planktonic Cnidaria

Journal of Biological Research, 2009
Biotoxin production is a characterizing aspect of the physiology and ecology of several marine organisms. In this study the cytotoxic effect of crude extracts from jellyfish Pelagia noctiluca, Chrysaora hysoscella and Aurelia aurita (Cnidaria: Scyphozoa)

Limited Dispersal of Benthic Environmental DNA From a Subtropical Mesophotic Shelf‐Edge Bank

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated the vertical and horizontal dispersion of eDNA away from an isolated mesophotic coral reef (Bright Bank) in stratified offshore waters. We found that vertical transport of benthic eDNA was limited by water column stratification and that the prevalence of eDNA from benthic invertebrates declined with horizontal distance away from the ...

A new Byronia species from the Late Ordovician of Estonia [PDF]

Estonian Journal of Earth Sciences, 2016
A new species of a possible thecate scyphozoan Byronia jaegeri sp. nov. is described from the late Katian of Estonia. This new taxon is distinct as it lacks the longitudinal ornamentation present in other Byronia species.

Biomass‐to‐volume ratio as a central continuous functional trait for marine zooplankton

Limnology and Oceanography, Volume 70, Issue 9, Page 2673-2687, September 2025.
Abstract Gelatinous zooplankton are an important component of many ecosystems and important for ecosystem structure and carbon cycling. However, this group is generally not considered in biogeochemical models. Here we investigate the biomass‐to‐volume ratio as an underappreciated “master trait” that allows for the incorporation of a large diversity of ...
