- МатериалЛичинки трематод - паразиты черноморского моллюска Nassa reticulata var. pontica Mont..(Наукова думка, 1965) Долгих, А. В.Widely found in the Atlantic Ocean and as far to the east as the Sea of Azov Nassa reticulata L.A prevails among gastropods. Larvae of Nassa largely contribute to plankton and adults to benthos, where, like other molluscs, they are common prey for fish of Labridae family. In the early XX century it was found that some N. reticulata from the Black Sea were infested with cercariae and metacercariae of Cercaria inconstans (Sinitsin, 1911), later re-identified as Diphterostomum brusinae Stoss (Palombi, 1930) adults of which are known to parasite fishes of families Labridae, Blennidae, and others. In the Mediterranean Sea parasitic fauna of N. reticulate has not been studied. At present (1964) it is known that Nassa reticulate harbours six cercaria larvae: Cercaria sagitata Lespès, 1857; C. hymenocerca Villot, 1875; C. fascicularis Villot, 1875; (C.) Diphterostomum brusinae (Stoss., 1889) Stoss., 1904; Cercariaeum reticulatum Stunkard, 1932 and unidentified rediae with furcocercariae.
- МатериалК изучению Ostracoda Азовского и Черного морей(Наукова думка, 1965) Шорников, Е. И.Ostracods which represent subfamilies Loxoconchinae G.O. Sars and Paradoxostominae Brady et Norman and inhabit the Black Sea and the Sea of Azov are discussed. Samples taken near the Crimean and the Caucasian shores of the Black Sea and in the Bosphorus area by researchers of the Sevastopol Biological Station and samples collected by the author from different areas of the Black Sea and the Sea of Azov (700 samples altogether) were examined. As the result, the biology and distribution of species already acknowledged for the two seas were defined more accurately and some new forms found. Several samples from different locations of the Mediterranean Sea were kindly offered by M.I. Kiseleva (Sevastopol Biological Station) that enabled comparison between some ostracods from the Azov-Black sea basin and the forms from the Mediterranean Sea. The recent record includes 25 species out of which some are new, first found in the Azov-Black sea basin and in the Soviet sector of the Black Sea (7, 3 and 8, correspondingly).
- МатериалНовый вид свободноживущей нематоды из Черного моря(Наукова думка, 1965) Платонова, Т. А.The Black Sea is one of the global water bodies having been thoroughly studied for fauna of free-living nematodes. In this context the works by I.N. Philipiyev (1918, 1922) are of primary significance. Some foreign scientists (Gerlach, 1951; Paladian, 1962) have also paid tribute to Black Sea nematodes as a research object. Hypothetically, Mediterranean species not occurring in the main basin of the sea can be found only in the Bosphorus area where nematological investigations have not been conducted as yet. However, when handling the set of samples collected from the Black Sea by researches of the Laboratory of Benthos, IBSS we found a new free-living nematode attributed to genus Rhabdodemania (Enoplida, Leptosomatidae). This finding was an unexpected contribution to the extensive scientific evidence already available. It is noteworthy that nematodes of this genus are found in the Black Sea for the first time.
- МатериалМорские клещи в донных биоценозах у северного побережья Кавказа(Наукова думка, 1965) Маккавеева, Е. Б.Little is known about marine mites dwelling in bottom biocenoses of the Black Sea; the sporadic studies were carried out in the Bulgarian sector of the sea in the near-shore strip down to the depth of 40 m (Chichkoff, 1907), in the vicinity of Sevastopol (Viets,1928; Makkaveyeva, 1961) and near the coast of Romania (Motas et Soares, 1940). The biocenosis of Cystoseira growing in Sevastopol seawater area was the only site in which seasonal changes in the life cycle of Black sea mites were observed (Makkaveyeva, Ph.D.Thesis). The recent investigation was conducted using the material collected in the Black Sea near the Caucasian coast in October 1958 and in June 1962. It was found that some seabed substrates such as phaseoline and mussel-bed silts, muddy shell debris, the muddy sand and shell debris with eelgrass growth give shelter to 7 species of saltwater mites among which Halacarus basteri var. affinis dominate. At the depths from 37 to 150 m H. basteri var. affinis was the most abundant species and within the depth range of 8 - 37 m – and P. punctatum. Species which were found on the bottom grounds near the Caucasus were also described for the coastal zone of Bulgaria (Chichkoff, 1907). Fauna of saltwater mites which inhabit 100 – 150 m depths is represented by two key species – H. basteri var. affinis and Copidognathus gracilipes; they are among some few organisms that can survive in the extreme depth of the Black Sea.
