Using stable isotopes to describe the trophic structure of gelatinous zooplankton across the deep pelagic

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 ...

Comparative feeding behavior of planktonic ctenophores [PDF]

Integrative and Comparative Biology, 2007
The phylum Ctenophora (known as comb jellies) consists of gelatinous marine carnivores found from the surface to several thousand meters depth. Their morphology can be simple or complex, ranging from a sac-like shape with no tentacles to large lobed forms with sinuous "auricles," papillae, and two different kinds of tentacles. This diversity appears to

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

Associations between fishes (Actinopterygii: Teleostei) and anthozoans (Anthozoa: Hexacorallia) in epipelagic waters based on in situ records

Journal of Fish Biology, Volume 107, Issue 6, Page 2166-2172, December 2025.
Abstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.

Potential pathways of invasion and dispersal of Mnemiopsis leidyi A. Agassiz 1865 in the Baltic Sea [PDF]

, 2010
The rapid spread of Mnemiopsis leidyi across the entire Baltic Sea after its first observation in 2006 gave rise to the question of its invasion pathway and the possible vector of its transport. To investigate pathways of M.

Planktonic larval stages—an adaptation to lower predation rates in the pelagic environment?

Limnology and Oceanography, Volume 70, Issue 11, Page 3417-3430, November 2025.
Abstract A majority of marine benthic macroinvertebrate and fish species have planktonic larval stages that disperse in the water column from days to months. However, the adaptive significance of pelagic larvae, and whether predation is higher in the pelagic or the benthic environment, is still debated, partly due to a lack of studies assessing larval ...

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

EvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

Review of environmental factors influencing distributions of selected Baltic species [PDF]

, 2015
This report presents a brief overview of ecologically or economically important species of different habitats and trophic levels in the Baltic. It supplies the modeling groups within BIO C3 with species specific information on environmental tolerances ...

Winter Diets of Pacific Salmon in the North Pacific

Fisheries Oceanography, Volume 34, Issue 6, Page 118-138, November 2025.
ABSTRACT The winter feeding ecology of Pacific salmon and Steelhead trout in the North Pacific Ocean was investigated, with a focus on species‐specific diets and interannual and spatial variability in diet composition. We used results from the 2022 International Year of the Salmon Pan‐Pacific Expedition to examine diet composition across the North ...
