“…The number of samples must substantially exceed three in order to identify the minimum existing differences between stations ( (Table 2). These study sites vary significantly in species composition, habitus, and community growth conditions [5,14]. It is not surprising that the biomass of each species of studied algae at the sampling sites varies greatly between paricular samples, for example, at the site no.…”

“…We tested the vegetation mapping on the coast of the Kola Bay of the Barents Sea earlier [5,14]. During these studies, the maps of the types of macroalgae communities and of the distribution of macrophytobenthos, including that in terms of biomass, were developed for the littoral and sublittoral of the Kola Bay.…”

“…For example, the biomass of kelp algae, primarily Laminaria solidingula, as well as Saccharina latissima and Alaria esculenta, together with related species, averages only 0.067 kg m 2 in the Beaufort Sea, Alaska [4]. In the Russian Arctic, macroalgae form a vegetation cover only along the Murmansk Coast, they are noted eastwards off only in some areas with the most suitable substrates [5]. Arctic algal communities are mostly sparse; therefore, it is necessary to minimize the seizure of algae so as not to harm both their populations and the ecosystem as a whole in studies of any kind.…”

The minimum number of samples was estimated based on the studies of the distribution of macrophytobenthos. The existing norms of three replicates per sampling station do not always allow to obtain reliable average values. The collection of a large number of samples, especially seasonally, will lead to significant changes in the studied community. It is recommended to put into practice the use of the method of photographing the areas of particular size along transects for further analysis using special software. It is proposed also to amend the existing regulatory documents on sampling of macrophytobenthos in the Barents Sea and other seas of the Russian Arctic. In particular, it is worth making the most of landscape surveys and mapping. The development of a monitoring system for species diversity and macrophytobenthos distribution in the seas of the Russian Arctic is justified in regard to the monitoring of the community state, including that considering the climate change.

“…The water temperature was observed to increase from Hornsund to Isfjorden and Grønfjorden, and more Atlantic Water was found to be flowing into Isfjorden, where a significant variability in water temperature and salinity was recorded (Moiseev & Gromov 2009). The state of Grønfjorden's MPB has been described by several researchers (Ryžik & Voskobojnikov 2003;Matišov et al 2004;Malavenda et al 2017;Malavenda et al 2018), who reported that a pronounced cover of bottom vegetation was characteristic of only the upper sublittoral zone at depths of 1-23 m. The average length and weight of thalli of Laminaria and Saccharina algae in Grønfjorden were similar to those observed at the Murman coast, whereas the maximal age of the thalli along the Murman coast was four years, compared with three years in Grønfjorden (Vozžinskaja et al 1992;Matišov et al 2004). At the mouth part of Grønfjorden, the biomass (wet weight) of Laminaria or Saccharina algae may reach 60 kg m -² and in the middle part of the fjord, near the Barentsburg harbour, it is 15 kg m -² (Ryžik & Voskobojnikov 2005).…”

“…According to available data (Malavenda et al 2017), the bottom macroalgae of the Pechora Sea are represented by 64 species: 9 Chlorophyta, 18 Phaeophyta, and 37 Rhodophyta. Marine vegetation is formed mainly by brown and red algae, and the communities are dominated by perennial forms, although green algae are rare.…”

Pechora Sea ecosystems: current state and future challenges

The southeastern part of the Barents Sea, conventionally called the Pechora Sea, is among the most peculiar regions of the European Arctic. It is a shallow shelf area that is directly influenced by modified Atlantic and Arctic waters, as well as by freshwater runoff from the Pechora River. Due to its unique environmental features and habitats, the Pechora Sea is regarded as one of the most important areas of the Barents Sea. Rich planktonic and benthic communities, including extensive mussel beds, support large stocks of fish, seals, and walruses, and enormous gatherings of benthos feeding waterfowl. In recent years, economic activities, such as oil and gas production, shipping of crude oil through marine terminals, and ship traffic along the Northern Sea Route, have dramatically increased in the Pechora Sea. These anthropogenic pressures, as well as the observed and predicted natural environmental changes, will most likely affect the sea's pelagic and benthic ecosystems. Therefore, information on the current state of the Pechora Sea ecosystems is urgently needed to provide baseline reference data, against which possible future shifts can be determined. The research presented in this special issue provides such data on the most important elements of the Pechora Sea ecosystems and adjacent areas and demonstrates the interconnection between these ecosystem components and key environmental factors. Considering the already recorded and potential changes in this region, the observed trends and processes in marine biota can be applied to other low Arctic seas and serve for modelling and predictions of future ecosystem shifts.
