Shallow-Water Bryozoan Communities in a Glacier Fjord of West Svalbard, Norway: Species Composition and Effects of Environmental Factors.

Despite significant research efforts focused on benthic assemblages in West Spitsbergen, there is a lack of knowledge regarding the shallow water bryozoan communities in Grønfjorden, a glacier fjord belonging to the Isfjorden system, Norway. Here, we studied species composition, richness, distribution, and biomass of bryozoans in the intertidal and upper subtidal zones of Grønfjorden in summer. We found 62 bryozoan species, among which (Linnaeus, 1767), (Busk, 1855), and (d'Orbigny, 1853) were most prevalent while the highest contributions to the total biomass were registered for (d'Orbigny, 1853), (Van Beneden, 1848), (Lamarck, 1816), and (Ellis and Solander, 1786).

Fatty Acid Profiles in the Gonads of Red King Crab () from the Barents Sea.

Red king crab () is a large shelf species native to the Pacific Ocean. Due to its high commercial value, this species was introduced into the Barents Sea, where it has formed a new population that now supports a stable commercial fishery. Information on fatty acid profiles in different tissues of the Barents Sea is scarce.

Summer-fall macrozooplankton assemblages in a large Arctic estuarine zone (south-eastern Barents Sea): Environmental drivers of spatial distribution.

Macrozooplankton assemblages were studied during the summer and fall of 2012 in the Pechora Sea, a large coastal region of the south-eastern Barents Sea strongly affected by discharges of freshwater. Sampling was performed at 23 stations with 550-μm mesh IKS-80 nets. We focused on macrozooplankton and large (>1.

Sex Hormones in Hemolymph of Red King Crabs from the Barents Sea.

The presence of vertebrate-related steroid sex hormones has been reported in both freshwater and marine crustaceans. However, despite the commercial importance of king crabs, many aspects of their endocrinology are still unknown. For this reason, we examined hemolymph samples of the red king crab from the Barents Sea population for the presence of testosterone and 17β-estradiol using radioimmunoassay.

New Echinoderm-Crab Epibiotic Associations from the Coastal Barents Sea.

During diving surveys for a Russian research project that monitored introduced species, red king crabs () were collected at a coastal site of the Barents Sea to study the structure and dynamics of this species. Sampling of the organisms colonizing the crabs was part of this research project. For the first time, the presence of relatively large specimens of the common starfish as epibionts of was observed in July 2010, 2018, and 2019.

[Content of alginic acid and fucoidan in fucus algae of the Barents sea].

Seasonal changes in the content of alginic acid and fucoidan have been studied in four species of fucus algae from the Barents sea: Fucus vesiculosus, F. distichus, F. serratus, and Ascophyllum nodosum.
