Fatty Acids and Stomach Contents Reveal Dietary Overlaps of Two Prospering Squid Species in the North Sea. [PDF]

Ecol Evol
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). Stomach content analysis

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

MetaZooGene Intercalibration Experiment (MZG-ICE): Metabarcoding Marine Zooplankton Diversity of the Global Ocean. [PDF]

Mol Ecol Resour
ABSTRACT DNA metabarcoding of zooplankton biodiversity is used increasingly for monitoring global ocean ecosystems, requiring comparable data from different research laboratories and ocean regions. The MetaZooGene Intercalibration Experiment (MZG‐ICE) was designed to examine1 and analyse patterns of variation of DNA sequence data resulting from multi ...

High-Throughput DNA Sequencing Reveals Gastric Content Composition and Inter-Specific Variation in <i>Pampus</i> Fishes. [PDF]

Ecol Evol
In this study, we employed high‐throughput sequencing of environmental DNA (eDNA) to conduct an analysis of the gastric contents composition and relative abundance from samples of P. argenteus and P. punctatissimus collected at the Jimiya Fish Pier in Qingdao, Shandong Province, and P. cinereus collected at the Qinglan Port in Wenchang, Hainan Province.

New group of the Early Palaeozoic conodont-like fossils [PDF]

Estonian Journal of Earth Sciences, 2015
The paper is devoted to the Upper Cambrian and Tremadocian organophosphatic microfossils which were hitherto treated as conodonts and assigned mainly to the genera Coelocerodontus and Viirodus.

Characterization of the zooplankton in the continental shelf of the Brazilian Equatorial Atlantic

Boletim do Instituto de Pesca, 2023
The equatorial Atlantic is characterized by its high abundance of zooplankton. However, starting point studies concerning the species composition in the northern Brazilian continental shelf are still scarce.

Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans [PDF]

, 2017
The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws supports an inclusion in Gnathifera nested in the Spiralia.

Tables and diagrams on trophology of walleye pollock in the western Bering Sea

Известия ТИНРО, 2016
State of zooplankton, as the food base of walleye pollock, in the western Bering Sea in the early 21st century is considered. Warm period of the 2001-2006 changed to cold period of the 2007-2013 and, after the transitional year of 2014, a new warm period

A new look at the ventral nerve centre of Sagitta: implications for the phylogenetic position of Chaetognatha (arrow worms) and the evolution of the bilaterian nervous system

Frontiers in Zoology, 2007
Background The Chaetognatha (arrow worms) are a group of marine carnivores whose phylogenetic relationships are still vigorously debated. Molecular studies have as yet failed to come up with a stable hypothesis on their phylogenetic position.

Distribution, abundance and biomass of Chaetognaths off São Sebastião region, Brazil in February 1994

Brazilian Journal of Oceanography, 2002
The distribution, abundance, biomass, population structure and feeding habits of chaetognaths collected off São Sebastião region, Brazil, in February 1994 are described. Bongo nets were hauled obliquely to collect zooplankton samples. Forty-three samples
