Изучен видовой состав микроскопических водорослей 14 лиманов Северо-Западного
Причерноморья (СЗП). В течение 1982–2017 гг. на 103 станциях было отобрано и
обработано 1817 проб, изготовлено и просмотрено 1200 постоянных препаратов.
Представлены данные о 544 видах микроскопических водорослей лиманов СЗП,
относящихся к 187 родам, 89 семействам, 49 порядкам, 11 классам и 8 отделам. В
альгофлоре лиманов преобладали представители отделов Bacillariophyta (372 вида),
Cyanoprokaryota (79) и Chlorophyta (54). Роды Nitzschia Hassall (39 видов), Navicula Bory
(31), Amphora Ehrenb. (20), Tryblionella W. Sm. (12), Gyrosigma Hassall (11), Diploneis
Ehrenb. (11), Phormidium Kütz. ex Gomont (10), Cocconeis Ehrenb. (9), Surirella Turpin
(10), Сymbella C. Agardh (9) представляли основу видового состава микроскопических водорослей лиманов. Наибольшее таксономическое разнообразие
отмечено для Днестровского лимана (296 видов), найменьшее — для Дофиновского
(30). В альгофлоре выявлено 23 новых вида для водоемов СЗП, 14 новых видов для
территории Украины, 3 новых вида для акватории Черного моря и 3 новых вида для
науки. Альгофлора причерноморских лиманов была пресноводно-солоноватоводной,
алкалифильной и β-мезосапробной. В ней отмечены пресноводные (318 видов),
солоноватоводные (107) и морские (117) организмы. По отношению к разным типам
субстратов в обрастаниях макрофитов найдено 398 видов микроскопических
водорослей, в обрастаниях камней — 166, створок моллюсков — 136, бетонных
сооружений — 125, балянусов — 27, в толще пены — 78, льда — 14, на илистых и
песчаных грунтах — 400 и 277 видов соответственно. Альгофлора лиманов СЗП с
точки зрения биогеографии представлена космополитной (340 видов) и бореальной
(150) группами с бореально-нотальными (22), северо-альпийскими (11), бореальнотропическими (13), аркто-бореальными (5) и тропическими (1) элементами.
The species composition of microscopic algae of 14 estuaries of the North-Western Black Sea (NWBS) coast has been studied. During the period of 1982−2017, 1817 samples were collected and processed аt 103 sampling stations; 1200 permanent slides were prepared and examined. A total of 544 species of microalgae were revealed in benthos of the estuaries located in the NWBS Region. They belonged to 187 genera, 89 families, 49 orders, 11 classes, and 8 divisions of algae. Bacillariophyta (372 species), Cyanoprokaryota (79), and Chlorophyta (54) led in species diversity. The richest genera are Nitzschia Hassall (39 species), Navicula Bory (31), Amphora Ehrenb. (20), Tryblionella W. Sm. (12), Gyrosigma Hassall (11), Diploneis Ehrenb. (11), Phormidium Kütz. (10), Cocconeis Ehrenb. (9), Surirella Turpin (10), and Cymbella C. Agardh (9). Among estuaries, the Dniester Estuary led in diversity of microphytobenthos (296 species); the Dofinovsky Estuary was the poorest in terms of species number (30). Revealed species included 26 species first cited for the study area; among them, 15 species are new for the flora of Ukraine, four species are new records for the Black Sea, and three species are new for science. According to the ratio of ecological groups of algae, algal flora of the NWBS estuaries is freshwater-brackish, alkaliphilic, and β-mesosaprobic. In terms of salinity tolerance, revealed species belong to groups of freshwater (318 species), brackish (107), and marine (117) forms. Substrates found in microphytobenthos communities included 400 species on the silty bottom, and 277 on the sandy bottom. There were 398 periphytic species found on macrophytes, 166 species on stones, 136 on shells of molluscs, 125 species inhabited concrete constructions, 27 species of algae occurred on barnacles, 78 species were found in foam, and 14 — in ice. In terms of biogeography, algal flora of the NWBS estuaries were represented by species with cosmopolitan (340) and boreal (150) distribution; the last group includes boreal-natal (22), north-alpine (11), boreal-tropical (13), arctic-boreal (5), and tropical (1) elements.
