Unbranched Holdfasts of Stemmed Echinoderms from the Ordovician of the Leningrad Region
Published in Paleontological Journal
Abstract—Based on examination of the collection of stemmed echinoderm holdfasts from the Ordovician of the Leningrad Region (Russia), all holdfasts are divided in two large groups: “unbranched” and “branched”. In total, 11 morphotypes of unbranched holdfasts are identified and described in detail.
The benthos: the ocean’s last boundary?
Benthic communities depend on receiving much of their food from the water column. While sinking, particles are transformed in a discontinuous process and are temporally retained in transitional physical structures, which act as boundaries and contribute to their further transformation. Motile organisms are well-acquainted with boundaries. The numbe...
Bioluminescence in an Undescribed Species of Carnivorous Sponge (Cladorhizidae) From the Deep Sea
One dominant ecological trait in the dimly-lit deep-sea is the ability of organisms to emit bioluminescence. Despite its many ecological roles in deep-sea ecosystems, the presence of inherent bioluminescence in marine sponges has been debated for more than a century. This work reports repeated observations of luminescence from six individuals of an...
Long-Term Dynamics of Benthic Communities: Editor’s Note
Published in Biology Bulletin
AbstractA brief review of the recent state of research on the dynamics of sea-bottom communities is given together with a revision of the basic concepts and models. It precedes a special issue of the Journal devoted to the results of particular studies on benthic communities on different spatial and temporal scales.
Variation in zoobenthic blue carbon in the Arctic's Barents Sea shelf sediments.
Published in Philosophical transactions. Series A, Mathematical, physical, and engineering sciences
The flow of carbon from atmosphere to sediment fauna and sediments reduces atmospheric CO2, which in turn reduces warming. Here, during the Changing Arctic Ocean Seafloor programme, we use comparable methods to those used in the Antarctic (vertical, calibrated camera drops and trawl-collected specimens) to calculate the standing stock of zoobenthic...
Diversity of benthic marine mollusks of the Strait of Magellan, Chile ( Polyplacophora , Gastropoda , Bivalvia ): a hist...
Published in ZooKeys
An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel b...
Portlandia-dominated Communities in the Arctic: Taxonomic Composition and Structure along the Geographical Gradient
Published in Doklady Earth Sciences
AbstractThe species composition and structure of bottom communities with a predominance of bivalve mollusks of the Portlandia genus, which are widespread on the shelf of the Russian Arctic, were analyzed. Molecular genetic analysis confirmed that Portlandia aestuariorum and P. arctica are valid species; it has been shown that all P. arctica from di...
Habitat factors differentiating the occurrence of Ostracoda (Crustacea) in the floodplain of a small lowland River Krąpi...
Published in Knowledge & Management of Aquatic Ecosystems
We analysed the occurrence of ostracods in a small river, taking into account all the types of water bodies in the floodplain − these included helocrenes, oxbow lakes, and ponds, as well as the main river channel. The objective of the study was to investigate the variation in ostracod communities and identify those factors determining species distr...
Small Lakes Ecosystems under the Impact of Non-Ferrous Metallurgy (Russia, Murmansk Region)
This paper presents integrated research on ecosystems of small lakes experiencing the direct impact of a copper-nickel ore processing plant, the &ldquo / Kolskaya GMK&rdquo / (MS KGMK), near the town of Monchegorsk Kola Peninsula, Russia. An integrated research method with the analysis of both abiotic and biotic components of aquatic ecosystems was...
