“…In the north-western Black Sea, the ecological, taxonomy and structure features of meiobenthos taxa are well studied (Vorobyova et al, 2008(Vorobyova et al, , 2017Vorobyova, Kulakova, 2009). Meiobenthic organisms were registered at the all types of habitats either natural or artifi cial origin, including plastic marine litter (Vorobyova, 1999;Snigirova et al, 2020;Uzun, Portianko, 2021). A large amount of studies in this part of the sea focusing on the ostracodes species diversity was conducted during 1960-1970(Caraion, 1960Marinov, 1962;Schornikov, 1967Schornikov, , 1969.…”

Data about meiobenthic ostracodes species on the different substrates of Zmiiniy Island nearshore water area are presented. The density and biomass means of the ostracodes were higher on the algal substrates (on Laurencia paniculata made up 41931 ± 12689 ind.·m-2 and 400.56 ± 125.65 mg·m-2 respectively). In the current study for the first time 13 ostracodes species were found, most of which are common in all types of substrate. The dominant species were Loxoconcha pontica Klie, 1937, Paradoxostoma intermedium Müller, 1894, Xestoleberis cornelii Caraion, 1963 and Xestoleberis decipiens (Müller, 1894). All of them are common species in the north-western Black Sea. Non-metric multidimensional scaling (nMDS) analysis of ostracodes species abundance shown that the samples of sandy-shells bottom differed significantly from algal and mussel substrates. According to the cluster analysis sand-shells bottom samples on almost 80 % differed from hard substrates.

This study provided a preliminary comparative analysis of meiobenthic assemblages in different habitats of the Snake Island Marine Protected Area (MPA). Meiobenthos was studied in three habitats: Exposed Black Sea upper infralittoral rock with Corallinales turf (MB142), Mytilid dominated exposed Black Sea upper infralittoral rock with foliose algae (no Fucales) (MB143) and Black Sea infralittoral sand and muddy sand without macroalgae (MB542). A total of 10 higher meiobenthos taxa were recorded in the different habitats: 5 permanent groups (Platyhelminthes, Nematoda, Harpacticoida (Copepoda), Ostracoda, Halacaridae) and 5 temporary groups (Oligochaeta, Polychaeta, Bivalvia, Gastropoda, Cyrripedia). The preliminary study of meiobenthos in the habitats of the Snake Island MPA showed that habitat MB143 was more favourable for meiobenthos, with the highest mean density and biomass (190655 ± 23004 ind.-m-2 and 3170.90 ± 412.15 mg-m-2, respectively). The comparative nMDS and cluster analyses based on the density of meiobenthos taxa in the Snake Island MPA showed that the meiofauna of both MB142 and MB143 differed significantly from the MB542 habitat, with Bivalvia and Ostracoda making the largest percentage contribution to these differences. The meiobenthos assemblages in the different habitats of the Snake Island MPA were similar to the other regions of the Black Sea with some unique features (e.g. relatively lower total meiobenthos density, high percentage of ostracodes on the algal substrate, etc.). Further studies on the characteristics of meiobenthos taxa assemblages in other Black Sea MPAs could lead to the estimation of meiobenthos assemblage patterns and their possible use in biomonitoring.

Despite long-term research on marine litter there is still insufficient knowledge about benthic organisms associated with these substrates, especially experimental studies and methodology of sampling for complex biofouling assemblages. To predict the fate of plastic in the marine environment it is necessary to know how long the macrolitter can stay in different sea matrices and what are the steps of colonisation by marine organisms. The experiments were carried out during various seasons in situ in the north-western Black Sea coastal area. Three new types of the experimental constructions intended for different durations of exposure (1–10 months) were designed. This article is the first to present the methodology and the results of complex experiments investigating marine fouling (from microalgae to meio- and macrofauna) on plastic surfaces. Overall, 28 genera of microalgae, 13 major groups of meiobenthos and 36 species of macrofauna were found on plastic during the experiments. The microalgae fouling was mainly formed by representatives of genus Cocconeis. The species composition of microalgae was common for the research area. The average density and biomass of meiobenthos were the greatest on I construction type after 8 months of exposure. In the total macrozoobenthos biomass and density of Bivalvia and Crustacea dominated, respectively. The obtained results on the interaction between fouling organisms and plastic materials in the marine environment form an important contribution to the understanding of the "good ecological status" of the sea. Additional studies based on the tested methodology could be used as a component of ecological monitoring during development and implementation of the approaches of the Marine Strategy (descriptor 10).
