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 ...

Morphology, Swimming Performance and Propulsive Mode of Six Co-occurring Hydromedusae [PDF]

, 2002
Jet propulsion, based on examples from the Hydrozoa, has served as a valuable model for swimming by medusae. However, cnidarian medusae span several taxonomic classes (collectively known as the Medusazoa) and represent a diverse array of morphologies and

Questioning the rise of gelatinous zooplankton in the World's oceans [PDF]

, 2012
During the past several decades, high numbers of gelatinous zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are ...

The influence of the Atlantic and regional climate variability on the long-term changes in gelatinous carnivore populations in the northwestern Mediterranean [PDF]

, 2008
We investigated potential connections between climate and the population size of gelatinous carnivores in the northwestern Mediterranean. The interannual variability of large- and meso-scale climate factors was related to gelatinous carnivore dynamics by

Resolving abrupt frontal gradients in zooplankton community composition and marine snow fields with an autonomous Zooglider

Limnology and Oceanography, Volume 70, Issue S1, Page S102-S120, July 2025.
Abstract An autonomous Zooglider navigated across the California Current Front into low salinity, minty waters characteristic of the California Current proper in both summers of 2019 and 2021. Diving to 400 m depth, Zooglider transited another near‐surface frontal gradient somewhat inshore. These frontal gradients were generally associated with changes

Seasonal Changes of Size Spectra of the Benguela Offshore Mesopelagic Ecosystem Compartment in Relation to Primary Production

Marine Ecology, Volume 46, Issue 4, July/August 2025.
ABSTRACT Seasonal differences in marine size spectra of micronekton at the shelf‐ocean interface of the northern (NBUS) and southern Benguela upwelling system (SBUS) in Feb–Mar 2019 and Sep–Oct 2021 were analysed for mesopelagic fishes and total micronekton, the latter also including invertebrates.

Hydromedusae (Cnidaria) of the Chilean southern channels (from the Corcovado Gulf to the Pulluche-Chacabuco Channels)

Scientia Marina, 2007
Hydromedusae collected in epipelagic waters of the channels in southern Chile, between the Corcovado Gulf and the Pulluche-Chacabuco channels, were analysed. A total of 23 species were identified and recorded for the first time in this region.

Metazoan Diversity and Its Drivers: An eDNA Survey in the Pacific Gateway of a Changing Arctic Ocean

Environmental DNA, Volume 7, Issue 2, March/April 2025.
In the face of climate change, organisms must adapt or shift their ranges to survive. Our study conducted the first COI marker‐based eDNA survey in the Pacific Gateway of the Arctic Ocean, analyzing seawater samples from the Bering Strait and Chukchi Sea.
