Deep-sea coral distribution on seamounts, oceanic islands, and continental slopes in the Northeast Atlantic [PDF]

open access: yes, 2007
A database of deep-water (\u3e 200 m) antipatharians, scleractinians, and gorgonians has been assembled for the NE Atlantic to determine what their distribution and diversity was before coral habitats became heavily impacted by bottom fishing gear ...

The macrozoobenthic community of the Santa Gilla lagoon (southern Sardinia, Italy) [PDF]

open access: yes, 2014
1 - Macrozoobenthos is one of the most significant communities of hydrobionts for assessing the ecological state of a water body. In spite of its importance, only few data concerning the macrobenthic community of Santa Gilla lagoon are available; 2 ...

Improved phylogenetic resolution within Siphonophora (Cnidaria) with implications for trait evolution

open access: yesbioRxiv, 2018
Siphonophores are a diverse group of hydrozoans (Cnidaria) that are found at all depths of the ocean - from the surface, like the familiar Portuguese man of war, to the deep sea. Siphonophores play an important role in ocean ecosystems, and are among the

Zooplankton and Picocyanobacteria Contribute Characteristic Size Ranges of Organic Particles to Different Layers of the Anoxic Water Column

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 7, July 2025.
Abstract Oxygen deficient zones (ODZs) are key areas of nitrogen loss, a process dependent on organic matter. Understanding the sources of organic matter in the ODZ is necessary to predict how biogeochemical cycles will respond to ocean changes. Size fractionated (5–20, 20–53, 53–180, 180–500, >500 μm) particulate organic C and N (POM) concentration ...

Phylogenetics of Hydroidolina (Hydrozoa: Cnidaria) [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 2008
Hydroidolina is a group of hydrozoans that includes Anthoathecata, Leptothecata and Siphonophorae. Previous phylogenetic analyses show strong support for Hydroidolina monophyly, but the relationships between and within its subgroups remain uncertain. In an effort to further clarify hydroidolinan relationships, we performed phylogenetic analyses on 97 ...

Recovery at Morvin: SERPENT final report [PDF]

open access: yes, 2010
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

Detection and distribution of Craspedacusta sowerbii: Observations of medusae are not enough [PDF]

open access: yes, 2012
The freshwater cnidarian Craspedacusta sowerbii, native to the Yangtze valley, has invaded lakes and ponds throughout the world. Most distribution records have to date been based on observations of the medusa (jellyfish) stage, including numerous recent ...

Phylogenomic Analyses Support Traditional Relationships within Cnidaria

open access: yesbioRxiv, 2015
Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic relationships among major ...

Population Dynamics of Ervilia castanea (Montagu, 1803) Hints at Evolutionary Processes Shaping North‐East Atlantic Insular Sandy Habitats

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Shallow‐water sandy habitats of volcanic oceanic islands are among the most geologically and ecologically dynamic marine habitats on Earth. We investigate the population genetic patterns of Ervilia castanea, an infaunal marine bivalve with a planktotrophic larvae inhabiting Macaronesian shallow‐water sandy habitats.

Stephanthus antarcticus, a new genus and species of sea anemone (Actiniaria, Haloclavidae) from the South Shetland Islands, Antarctica [PDF]

open access: yes, 2003
Stephanthus antarcticus gen. nov. et sp. nov. is described and illustrated from six specimens collected in the Antarctic Peninsula on the Polarstern cruises ANT XV/3 and ANT XIX/3. The new genus is characterised by the absence of sphincter and basilar
