Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Hydroidfest 2016: celebrating a renaissance in hydrozoan research

open access: yesEvoDevo, 2017
Hydroidfest 2016 took place on September 23–25 at the UC Davis Bodega Marine Laboratory in Bodega Bay, CA. The meeting brought together cnidarian researchers, with an emphasis on those studying hydrozoans, from North America and other parts of the world.

Gelatinous zooplankton net-collected in the Gulf of Maine and adjacent submarine canyons: new species, new family (Jeanbouilloniidae), taxonomic remarks and some parasites

open access: yesScientia Marina, 2006
A systematic account is provided of the siphonophores, medusae, ctenophores, molluscs and salps net-collected in basins of the Gulf of Maine and adjacent canyons during three cruises carried out in September 2002, 2003 and 2004.

Ultrastructural and immunocytochemical evidence of a colonial nervous system in hydroids

open access: yesFrontiers in Neural Circuits, 2023
BackgroundAs the sister group to all Bilateria, representatives of the phylum Cnidaria (sea anemones, corals, jellyfishes, and hydroids) possess a recognizable and well-developed nervous system and have attracted considerable attention over the years ...

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

Unexpected diversity and novel lineages in the cosmopolitan genus Nanomia (Cnidaria: Siphonophorae: Physonectae)

open access: yesFrontiers in Marine Science
Integrated use of molecular and morphological methods reveals unexpected diversity in the cosmopolitan siphonophore genus Nanomia. Species delimitation analyses based on COI and 16S sequences suggest up to three distinct lineages in addition to the ...

Acoustic Observations Unveil Seasonal Fluctuations and Regulation of Zooplankton Biomass and Its Vertical Distribution at a Mid‐Latitude Long‐Term Ocean Observatory

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Zooplanktonic organisms are considered a key link between different trophic levels. The ecosystem structure and dynamics are affected by changes in their population and phenology. In this work, the causes and timing of changes within the seasonal cycle of zooplankton biomass vertical distribution in oceanic waters of the Bay of Biscay were ...

Diurnal variations in the vertical distribution and abundance of zooplankton in the continental shelf waters off Cochin during April 1991 [PDF]

open access: yes, 1996
The present study is based on zooplankton samples collected by vertical hauls from 0-30, 30-60 and 60-90 m depths from a 100 m depth station in the continental shelf (09° 44' N, 75° 42*8) off Cochin for two days at three hourly interval.
