Trophic interactions of meso- and macrozooplankton and fish in the Iceland Sea as evaluated by fatty acid and stable isotope analysis [PDF]
, 2012 A trophic study was carried out in August of 2007 and 2008 on the pelagic ecosystem in the Subarctic Iceland Sea. Carbon and nitrogen stable isotopes and fatty acid biomarkers were used to study trophic linkages and the trophic ecology of the most ...

Ecology and Evolution, Volume 15, Issue 12, December 2025.Distribution ranges of cephalopods are expanding worldwide and their abundances are increasing due to ocean warming. Recently, the broadtail shortfin squid Illex coindetii (Ommastrephidae) expanded into the North Sea where it established a successful spawning stock beside the resident veined squid Loligo forbesii (Loliginidae).

A Large Cambrian Chaetognath with Supernumerary Grasping Spines [PDF]
Current Biology, 2017 Chaetognaths (arrow worms) are a separate phylum (Chaetognatha) of small carnivorous animals, dominantly pelagic, and a major component of today's plankton [1, 2]. The position of Chaetognatha among metazoan phyla remains equivocal-neither morphological nor molecular data provide definitive evidence [3]. Originating early in the Cambrian period [4], if

Extreme Mitogenomic Variation in Natural Populations of Chaetognaths [PDF]
Genome Biology and Evolution, 2017 The extent of within-species genetic variation across the diversity of animal life is an underexplored problem in ecology and evolution. Although neutral genetic variation should scale positively with population size, mitochondrial diversity levels are believed to show little variation across animal species.

Limnology and Oceanography, Volume 70, Issue 12, Page 3634-3649, December 2025.Abstract Although gelatinous zooplankton are key members of marine ecosystems and food webs, their trophic ecology is poorly described across the deep pelagic. We used stable carbon (bulk tissue) and nitrogen (bulk tissue and amino acid) isotope analysis to estimate the trophic positions (TPs) of abundant gelatinous zooplankton (chaetognaths ...

Studies on chaetognaths off Ubatuba region, Brazil: II. Feeding habits
Brazilian Journal of Oceanography, 1995 The diet of chaetognath species were studied by examining the gut contents of 9466 specimens collected off Ubatuba region, São Paulo State. The greatest proportion of chaetognaths (7119 individuals) showed their gut contents empty. Copepods, mollusc eggs,

Abundance, condition, and diet of juvenile Pacific ocean perch (Sebastes alutus) in the Aleutian Islands [PDF]
, 2009 T he relative value of pelagic habitat for three size classes of juvenile Pacific ocean perch (Sebastes alutus) was investigated by comparing their abundance and condition in two areas of the Aleutian Islands. Diet, zooplankton biomass, and water column

Food web modifications shifted the functional structure of zooplankton
Limnology and Oceanography, Volume 70, Issue 12, Page 3983-3997, December 2025.Abstract The North Sea has been undergoing long‐term transformations driven by shifts in human activities and climate change, which have jointly reshaped the composition of marine communities. Despite existing studies, the functional mechanisms driving community changes remain poorly understood.
