“…The content of silt+clay fractions and total organic carbon (C org ) of the sediments was also determined. Furthermore, chemical analysis of soft bottom sediments was conducted by colleagues from Institute of Colloid Chemistry and Water Chemistry NASU, Kiev (ICCWC) using previously described techniques (Burgess et al, 2009(Burgess et al, , 2011Petrov et al, 2010).…”

“…The analysis of technogenic pollutants content in soft sediments of DB confirmed the high ecological quality of this area, which was previously closed to any civil activity (Table 1). Very low content of the trace metals (Cu, Zn, Ni, Cr, Pb, Cd, Ag, and Hg) was detected, and the main classes of organic pollutants (PCBs, PAHs, and pesticides) found did not exceed average levels for the soft bottoms of environmentally intact offshore areas of the Black Sea shelf (Mitropolsky et al, 2006;Burgess et al, 2009Burgess et al, , 2011Samyshev et al, 2014). It has previously been shown that this set of pollutants can exert a strong influence on the quantitative development and spatial distribution of benthic diatoms Petrov et al, 2005Petrov et al, , 2010.…”

First-time research of the pristine water area of Dvuyakornaya Bay (South-Eastern Crimea, Black Sea) revealed high taxonomic richness of benthic diatoms (Bacillariophyta). Altogether, 304 species, 78 genera, 37 families and 20 orders were identified. Among them 68 newly-found species for the Black Sea were marked. The largest species number was marked in the genera Navicula (41 species), Nitzschia (29), Amphora (25), Cocconeis (20), Diploneis (16), Lyrella, Fallacia and Planothidium (10 species respectively). Inter-regional comparative analysis of diatom species richness was carried out using Bray-Curtis similarity coefficient and Venn diagrams. Diatom taxocene of Dvuyakornaya Bay (DB) was compared with Bacillariophyta flora from several Crimean coastal sites under different level of anthropogenic impact, i.e. relatively pristine water area near Cape Fiolent (CF) and heavy polluted Sevastopol Bay (SB) and Balaklava Bay (BB). The highest similarity of species composition (58%) was registered between intact biotopes (DB vs CF) and between heavy polluted water areas (SB vs BB), despite the geographical remoteness of the compared areas, differences in hydrological-hydrochemical conditions and in bottom substrates patterns. The lowest species similarity of diatom taxocenes was observed between SB and CF (32.3%) and between SB and DB (36.5%). It was concluded that the content of technogenic pollutants (trace metals, PCBs, PAHs and pesticides) in the bottom sediments, as well as the heterogeneity of microbiotopes are represent major factors influencing on the species composition of benthic Bacillariophyta in the investigated coastal water areas.

“…Very low content of key trace metals and organic pollutants was registered in the bottom sediments of Dvuyakornaya Bay and near Cape Fiolent; the content hardly exceeded the average levels (numbers in brackets, see Table 1) of these pollutants in surface soft bottoms of environmentally healthy coastal areas of the Black Sea shelf (Mitropolsky et al, 2006;Burgess et al, 2009Burgess et al, , 2011. The low level of pollution in sediments at Dvuyakornaya Bay and Cape Fiolent attributed these water areas to the category of conventionally pristine and characterized the structure of the diatom taxocenes in these biotopes as undisturbed.…”

An analysis of the taxonomic diversity of benthic diatoms was carried out for near-shore biotopes of Crimea with different content of trace metals and organic pollutants (PCBs, PAHs, DDTs). Taxonomic distinctness indices such as average taxonomic distinctness, AvTD (Δ + ) and variation in taxonomic distinctness, VarTD (Λ + ) were used for evaluation of the hierarchical structure of diatom taxocenes of two intact sites (Dvuyakornaya Bay and Cape Fiolent) and two heavily polluted water areas (Sevastopol Bay and Balaklava Bay). The highest similarity of species was revealed between healthy biotopes, in spite of their differences in hydrological and hydrochemical conditions. AvTD values for Dvuyakornaya Bay and Cape Fiolent (Δ + = 79.0 and 76.7, respectively) were lower in comparison with expected average levels (Δ + = 82.2) evaluated for the flora of benthic Bacillariophyta (1094 species) registered for the Northern part of the Black Sea (NPBS). As established, the taxonomic trees of the diatom taxocenes at pristine water areas are characterized by a moderate degree of vertical evenness and high variability of distances between neighboring clusters of species; they are mainly formed by polyspecific branches close on the genus level. The AvTD values for diatom taxocenes of the heavily polluted Sevastopol Bay (Δ + = 83.6) and Balaklava Bay (Δ + = 84.1) were significantly higher than the corresponding indices for undisturbed biotopes and exceeded the expected average level for the entire list of Bacillariophyta for NPBS. The upward trend of AvTD along the increasing technogenic impact can be caused by the disappearance of taxonomically close species with low tolerance from the same genus and prevalence of oligo-and monospecies branches in architectonics of the hierarchical tree. The present study shows that the application of TaxD indices can be considered an additional appropriate indicator tool for quantifying changes in the hierarchical structure of diatom taxocenes under persistent anthropogenic stress.

“…К наиболее токсичным из них относятся соли тяжелых металлов (Cu, Zn, Ni, Pb, Cd, Mn, Hg), хлорорганические соединения -полихлорбифенилы (ПХБ) и хлорорганические пестициды (ХОП), а также полиароматические нефтяные углеводороды (ПАУ). Выбор контрольной точки R3 обусловлен ее местонахождением у открытого побережья, на удалении от речного стока и источников поступления в морскую среду техногенных поллютантов (Burgess et al, 2011).…”
