Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Winter feeding during the spawning migration of capelin north of Iceland

Journal of Fish Biology, EarlyView.
Abstract Winter feeding during the spawning migration of capelin is often assumed to be minimal, because energy is allocated to reproduction. However, January–February surveys north of Iceland in 2018 and 2019 showed that prey occurred in 64% and 62% of 423 stomachs examined, respectively. Copepods (Calanus spp.) and euphausiids dominated the diet, and

Diversidad y distribución de la fracción de gran tamaño del mesozooplancton en hábitats costeros de tres golfos del Archipiélago cubano (Mar Caribe)

Revista de Investigaciones Marinas, 2023
El Archipiélago Cubano contiene una gran fracción de la diversidad regional pero no existen estudios recientes sobre el mesozooplancton. Nuestro objetivo fue caracterizar la fracción de tamaño grande (> 500 μm) del mesozooplancton a través de cuatro ...

The Sizes, Growth and Reproduction of Arrow Worms (Chaetognatha) in Light of the Gill-Oxygen Limitation Theory (GOLT)

Journal of Marine Science and Engineering, 2021
The Chaetognatha are a marine invertebrate phylum including 132 extant, carnivorous species in nine families and two orders, but with unclear protostomian affinities in the animal kingdom.

Species composition, seasonal abundance and population structure of chaetognaths in Admiralty Bay (Antarctic)

Polish Polar Research, 2016
Although chaetognaths inhabiting polar ecosystems are relatively well known, there are few reports on their functioning in the Antarctic coastal plankton community. The presented results provide the first comprehensive description of population structure

Macrozooplankton community structure and trophic interactions differ across a sub‐Antarctic shelf break, independent of Antarctic krill

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract The South Georgia continental shelf break is a highly productive and biodiverse region of the Southern Ocean, with abundant macrozooplankton forming the foundation of off‐ and on‐shelf communities. Antarctic krill (Euphausia superba) are a major component of these communities and can dominate total biomass.

Ultrastructure of Meelsvirus: A nuclear virus of arrow worms (phylum Chaetognatha) producing giant "tailed" virions. [PDF]

PLoS ONE, 2018
Most known giant viruses, i.e., viruses producing giant virions, parasitize amoebae and other unicellular eukaryotes. Although they vary in the level of dependence on host nuclear functions, their virions self-assemble in the host cell's cytoplasm.

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

Methods in Ecology and Evolution, Volume 17, Issue 10, Page 2895-2908, October 2026.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

Stable isotopes reveal that gelatinous zooplankton diets group by taxonomy and feeding traits in a coastal upwelling system

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Gelatinous zooplankton are abundant in marine ecosystems, yet their trophic roles and functional diversity in food webs have only recently gained attention. Gelatinous zooplankton taxa including hydromedusae, ctenophores, siphonophores, chaetognaths, and pelagic tunicates span multiple phyla and are often grouped taxonomically, but trait‐based

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,
