В донных отложениях Одесского региона выявлены пространственно-временные таксоценотические комплексы и внутрикомплексные группировки цист динофитовых водорослей на основе сходства таксономического состава и количественного распределения. Обнаружены цисты 26 таксонов водорослей, из которых 22 относились к 3 порядкам, 6 семействам, 7 родам (Scrippsie...

Spatial distribution of dinoflagellates cysts in the northern part of the Black Sea Fifteen different dinoflagellate cyst morphospecies were found in sediment samples collected in northern part of the Black Sea. Twelve cysts representing 8 genera were identified to the species level. The most common cysts were Scrippsiella trochoidea, Gymnodinium...

A total of 61 protist species belonging to four eukaryotic supertypes were obtained (Excavata – 23, SAR – 20, Eukaryota incertae sedis – 2, Amoebozoa – 1, and 15 species of uncertain systematic position). The greatest number of species belonged to Euglenida (22), Dinophyceae (7) and Thecofilosea (5 species). The communities of the coastline flagell...

The active protists community composition, abundance, biomass and size structure were evaluated and compared between two biotopes and three locations. A total of 61 protist species belonging to four eukaryotic supertypes were obtained, the coastline flagellates communities include 22 species, the sublittoral flagellates communities – 45 species.

Within the Cyanoprokaryota there are many species adapted to life in hyperhaline environments. Some can even grow at salt concentrations approaching NaCl saturation. Our research concerns changes in the species composition of organisms with a decrease in salinity of brine. Here, we present the results of the study of Cyanoprokaryota diversity in th...

При проращивании микроорганизмов из проб донных отложений, отобранных в разных частях Куяльницкого лимана, на питательной среде в диапазоне солености от 60 до 160 ‰ выявлено более 100 видов организмов, относящихся к разным систематическим группам. Автотрофный компонент сообщества организмов наряду с диатомовыми (25 видов) включал зеленые водоросли...

Abstract. The intensity of metabolic processes in algae is determined by a number of morpho-functional parameters, among which a special place is occupied by the specific surface (S/W). The greater the surface area per unit mass of the cell, the more actively metabolic processes proceed. As a result of the experiment on algologically pure cultures...

Исследования проводили в северо-западной части Черного моря на участке акватории между Сухим и Григорьевским лиманами (Одесский регион), а также в Дофиновском, Григорьевском и Тилигульском лиманах. В илах Одесского региона на глубине 10–25 м плотность цист была максимальной – от 300 до 5800 экз.г-1 сухого грунта. В зимний период показатели плотност...

Анотація The role of sand interstitial community in process of decomposition of different origin wrack (seaweed, seagrass and mussel) are considered in with the results of laboratory experiments. Quantitative changes of organic matter content, bacteria, marine fungi, microalgae, flagellates, ciliates and insects in wrack and underlying sand are st...

This work is a continuation of the publication "Biology of the north-western part of the Black Sea" (edited by KA Vinogradov, K .: Naukova Dumka, 1967). It summarizes the research materials of the ecosystem of the north-western part of the Black Sea, carried out during the period 1967-2003. The results of studying the abiotic component of the ecosy...
