349 Investigation of the effect of climatic changes on the environment is a topical direction in modern studies. Long-term fluctuations in the temperature of sea water determine changes in the structure of benthic communities and are reflected on quantitative characteristics of benthic invertebrates. Owing to confinement of benthos to certain communities(More)
The Barents Sea is a transition zone between North Atlantic and Arctic waters, so its marine ecosystem is highly sensitive to climate dynamics. Understanding of marine biota response to climate changes is necessary to assess the environmental stability and the state of marketable biological resources. These processes are analyzed using a database from the(More)
285 In Arctic seas, Crustacea is a widespread taxonomic group including a great variety of species. These invertebrates are capable of inhabiting a wide range of environments and populating nearly all benthic biotopes. Crustaceans rarely dominate the biomass of bottomdwelling communities, but their settlements may reach high densities. Detailed analysis of(More)
27 Long term surveys of the macrozoobenthos in the Barents Sea, along the Kola Meridian Section, showed the dependence of the species composition and quantitative parameters of the bottom fauna on the dynamics of the prevalent environmental factors [1–5]. The dynamics of bottom communities in gen eral and of the most abundant group of bottom inver tebrates,(More)
The composition and distribution of near-bottom amphipods in the southern part of the central Barents Sea were studied based on quantitative materials collected by expeditions of the Murmansk Marine Biological Institute in 1996–1997. A total of 144 amphipod species (on average 13 ± 1 species per station) were found; the average biomass was 0.49 ± 0.07 g/m2,(More)
Based on the data collected in five marine expeditions of the Murmansk Marine Biological Institute from 2002 through 2007, the spatial and temporary variability of benthic communities in the Central Depression of the Barents Sea (licensed plot of the Shtokmanovskoe condensed gas deposit) has been analyzed. The range of quantitative characteristics and the(More)
Crustaceans from the order Amphipoda were analyzed in 250 quantitative samples of macrozoobenthos collected at 50 stations during the voyage of the research ship Pomor in the southern part of the Kara Sea in September 1994 (Fig. 1). Benthos was sampled with a 0.1-m 2 drag, washed through a kapron screen with a mesh dimension of 0.5 mm, fixed in 4%(More)
353 The coastal zone of the eastern Murman is sub jected to intense anthropogenic activity in the spheres of power engineering, oil and gas industry, fishery and tourism. Therefore, at present, the necessity arises of broadening the knowledge about the state of the envi ronment and, in particular, of the state of the bottom fauna in this poorly studied(More)
149 Amphipods of the genus Gammarus are among the most abundant invertebrates in the littoral zone of Arctic seas. The distributions and abundances of dif ferent species of this genus depend on many factors, among which the water temperature and salinity are the most important [1, 2]. Therefore, the locations of individual species of Gammarus on the coasts(More)
455 Despite the long history of studying the benthos near the shores of Svalbard [1–5], only a few studies on the subject has been performed in Russia [1]. Since 1995, integrated studies performed in the Murmansk Marine Biological Institute of the Kola Scientific Center of the Russian Academy of Sciences have yielded abundant evidence on the benthic fauna(More)
