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

open access: yesNew 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.

Dos nuevos registros de medusas (Cnidaria: Cubozoa y Scyphozoa) en la Bahía de Acapulco, Guerrero, México

open access: yesRevista de Investigaciones Marinas, 2021
Durante el trabajo de campo rutinario en la bahía de Acapulco, México, en septiembre de 2019 se recolectaron por primera vez cuatro ejemplares de medusas pertenecientes a las especies Chiropsalmus alipes (Cubozoa) y a Stomolophus cf.

First description of wild-collected ephyrae of Lychnorhiza lucerna (Cnidaria, Scyphozoa)

open access: yesAnais da Academia Brasileira de Ciências, 2021
Ephyrae are the young scyphozoan jellyfishes that usually passes unnoticed, whereas their adult counterparts play major ecological roles and can negatively affect economic activities when they occur in high densities.

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

open access: yesJournal 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 ...

Global Neuropeptide Annotations From the Genomes and Transcriptomes of Cubozoa, Scyphozoa, Staurozoa (Cnidaria: Medusozoa), and Octocorallia (Cnidaria: Anthozoa)

open access: yesFrontiers in Endocrinology, 2019
During animal evolution, ancestral Cnidaria and Bilateria diverged more than 600 million years ago. The nervous systems of extant cnidarians are strongly peptidergic.

Raising Awareness of the Severity of “Contactless Stings” by Cassiopea Jellyfish and Kin

open access: yesAnimals, 2021
Discussion around avoidance and mitigation of jellyfish stings has traditionally focused on swimmers and divers being mindful of their behavior relative to swimming medusae (pelagic jellyfish).

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

open access: yesEnvironmental 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 ...

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.

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

open access: yesLimnology 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 ...
