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

Journal 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 ...

VARIACION ONTOGENETICA EN LA DIETA DE PATAGONOTOTHEN LONGIPES (STEINDACHNER 1876) (PERCIFORMES: NOTOTHENIIDAE) EN EL FIORDO DE CASTRO, CHILOE ONTOGENETIC VARIATION IN THE DIET OF PATAGONOTOTHEN LONGIPES (STEINDACHNER 1876) (PERCIFORMES: NOTOTHENIIDAE) IN THE FIORD OF CASTRO, CHILOE

Gayana, 2002
Patagonotothen longipes es un nototénido litoral que se distribuye geográficamente en Chile, desde Chiloé (42º29'S, 73º45'W) al sur. En el presente trabajo se analiza su ecología trófica, para lo cual se estudiaron 105 ejemplares capturados en ...

Horizontal and vertical distribution of mesozooplankton species richness and composition down to 2,300 m in the southwest Atlantic Ocean

Zoologia (Curitiba), 2014
We describe the species richness, distribution and composition of mesozooplankton over the continental shelf and slope, and in the water masses in the Campos Basin, southwest Atlantic Ocean. We analyzed the mesozooplankton from two oceanographic cruises (

Distribution of Euphausiacea in space and time in the Indian EEZ and contiguous seas [PDF]

, 1990
The Euphausiacea collected from 1,086 stations during the cruises 1-44 of FORV Sagar Sarnpada in the eastern Arabian Sea and the Bay of Bengal from 1985-'88 were studied for their spatial, seasonal and day and night abundance.

Ecology of euphausiacea along the southwest coast of India [PDF]

, 1985
The ecology of Euphausiacea (Crustacea) of the continental shelf waters along the southwest coast of India has been investigated by a study of the latitudinal and inshore-offshore movements of six species in relation to the environmental parameters ...

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 ...

Systematic sequencing of mRNA from the Antarctic krill (Euphausia superba) and first tissue specific transcriptional signature

BMC Genomics, 2008
Background Little is known about the genome sequences of Euphausiacea (krill) although these crustaceans are abundant components of the pelagic ecosystems in all oceans and used for aquaculture and pharmaceutical industry.

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.
