Environmental DNA surveys detect distinct metazoan communities across abyssal plains and seamounts in the western Clarion Clipperton Zone. [PDF]
Mol Ecol, 2020 Abstract The deep seafloor serves as a reservoir of biodiversity in the global ocean, with >80% of invertebrates at abyssal depths still undescribed. These diverse and remote deep‐sea communities are critically under‐sampled and increasingly threatened by anthropogenic impacts, including future polymetallic nodule mining.

Hidden gems: Scattered knowledge hampered freshwater jellyfish research over the past one-and-a-half centuries. [PDF]
Ecol EvolApproximately 150 years of research on freshwater jellyfish globally have resulted in a considerable amount of information. However, this is not comprehensively available to most researchers worldwide. Scattered information allows only for a fragmented view of the research field, which mediated by climate change received increasing importance.

Limnology and Oceanography, Volume 68, Issue 12, Page 2688-2702, December 2023., 2023 Abstract The effects of environmental change on zooplankton communities, and more broadly, pelagic ecosystems are difficult to predict due to the high diversity of ecological strategies and complex interspecific interactions within the zooplankton. Trait‐based approaches can define zooplankton functional groups with distinct responses to environmental ...

Integrating siphonophores into marine food‐web ecology
Limnology and Oceanography Letters, Volume 7, Issue 2, Page 81-95, April 2022., 2022 Abstract Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column. We (1) synthesize current knowledge about siphonophore trophic ecology and predator–prey interactions, (2) analyze siphonophore‐prey networks to compare food‐web topology ...

Diet of the gelatinous zooplankton in Hardangerfjord (Norway) and potential predatory impact by Aglantha digitale (Trachymedusae) [PDF]
Marine Ecology Progress Series, 1996 9 pages, 3 figures, 4 tables The abundance, spatial distribution and diet of the gelatinous zooplankton collected at 5 stations along the Hardangerfjord (Norway) in spring 1992 were investigated. Medusae and siphonophores dominated in abundance and were concentrated in the upper 50 in where a strong halocline (28.2 to 34.5 psu) was present. Obelia spp.

Scientia Marina, 2000 Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful information on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic

Scientia Marina, 1998 Two new species of hydromedusae (Foersteria antoniae and Cunina simplex) are described from plankton collected in sediment traps placed in the Lacaze-Duthiers Submarine Canyon and along Banyuls-sur-Mer coast (northwestern Mediterranean).

The Ultrastructure of the Radial Neuromuscular System of the Jellyfish Liriope tetraphylla (Hydrozoa, Trachymedusae): Implications in Crumpling Behavior [PDF]
The Biological Bulletin, 1991 The ultrastructure of the radial neuromuscular system of the trachymedusa Liriope tetraphylla was examined to determine the morphological substrate underlying crumpling behavior--the folding of the margin into the subumbrellar cavity by radial muscle contraction. These contractions are produced by the four smooth muscle bands that run the length of the

On a New Deep-Water Trachymedusa [PDF]
Journal of the Marine Biological Association of the United Kingdom, 1961 Anew species of deep-water txachymedusa from the North Atlantic is described and named Colobonema apicatum. Most specimens occurred deeper than 1500 m.

Zootaxa, 2010 Large numbers of a distinctive trachymedusa were observed at 1967 m depth just above the bottom in Suruga Bay, Japan, during a dive by the crewed submersible Shinkai 2000 in April 2002. Two individuals were collected and proved to be an undescribed species, herein described as Voragonema tatsunoko sp. nov. This species is characterised by the number (9)
