<p><strong>FIRST FINDING OF EPIBIONT PERITRICH AND SUCTORIAN CILIATES (CILIOPHORA) ON OLIGOCHAETES AND HARPACTICOID COPEPODS FROM THE DEEP-WATER HYPOXIC/ANOXIC CONDITIONS OF THE BLACK SEA</strong></p>

The concept of a new approach to environmental assessment is offered in the system of integrated management of the resource and environmental safety of the coastal area of the Black Sea. The studies of the season and daily changeability in the bioluminescence field in the Sevastopol coastal waters has been conducted. For the first time considerable differences in the bioluminescence field seasonal changes in the surface and deep water layers and the reasons conditioning this phenomenon have been shown, using a method of multidimensional statistical analysis. The bioluminescence field vertical profile change in the Black sea coastal waters in the autumn period at night has been studied. It has been shown that according to the character of bioluminescence parameters dynamics a water column can be divided into layers: upper (0 – 35 m) and deep water (36 – 60 m). It has been revealed that life rhythms of the plankton community are the main reason for the bioluminescence field intensity variability. It has been revealed that 14-hour periodicity of the bioluminescence field is related to the changes in light and its variations with 2,5…4,5 hours are conditioned by planktonts endogenous daily rhythms. And here biotic factors effect mostly periodicity of the bioluminescence field intensity increase and fall down at the dark time of the day. Abiotic factors are of less importance in circadian rhythmic of the bioluminescence field in the neritic zone.

First Time

Abstract The freshwater bryozoan Pectinatella magnifica (Leidy, 1851) was found for the first time in the Ukrainian part of the Danube Delta (Poludionniy arm, 45°25.00˝ N, 29°45.25˝ E) in 2005. Since then, it has increased in abundance. Th e greatest colony numbers occurred on both dead and living reed stems in the delta region 1.5-2.0 km upstream from the Black Sea.

AbstractMeiobenthic organisms were sampled for the first time from İğneada coasts, Turkey (Western Black Sea) in order to provide a base-line study on the meiobenthic community structure of the sampling area. Meiobenthos was found to be composed of 12 higher taxonomical groups: Nematoda, Harpacticoida, Polychaeta, recent hard-shelled Foraminifera, soft-shelled Foraminifera, Bivalvia, Gastropoda, Ostracoda, Turbellaria, Oligochaeta, Nemertea and Acari. Meiobenthic community was dominated by nematodes, harpacticoid copepods and hard-shelled foraminifera in the study area. Fifty two species of Nematoda, fifteen species of Harpacticoida and twelve species of living hard-shelled Foraminifera were identified. Six nematode species (

The Vertical Distribution

The results of investigations of tardigrades (2009-2010) in the Bosporus outlet area of the Black Sea are represented. For the first time two species of tardigrades Dipodarctus subterraneus (Renaud-Debyser, 1959) and Tanarctus ramazzottii (Renaud-Mornant, 1975) are recorded for the Black Sea. Tardigrades are registered on 4 stations at depths range 88-250 m. Average abundance of tardigrades widely varied from 141 to 11 440 ind./m2. The vertical distribution of tardigrades in the sediments was analyzed: most specimens (up to 98 %) found in the top 0-1 cm sediment layer.

First Time

We studied for the first time luminescence characteristics of the some micromycetes, isolated from the bottom sediments of the Black sea from the 27 m depth. Luminescence parameters were registered at laboratory complex “Svet” using mechanical and chemical stimulations. Fungi cultures of genera Acremonium, Aspergillus, Penicillium were isolated on ChDA medium which served as control. Culture of Penicillium commune gave no light emission with any kind of stimulation. Culture of Acremonium sp. has shown luminescence in the blue – green field of spectrum. Using chemical stimulation by fresh water we registered signals with luminescence energy (to 3.24 ± 0.11)•108 quantum•cm2 and duration up to 4.42 s, which 3 times exceeded analogous magnitudes in a group, stimulated by sea water (p < 0.05). Under chemical stimulation by ethyl alcohol fungi culture luminescence was not observed. Culture of Aspergillus fumigatus possessed the most expressed properties of luminescence. Stimulation by fresh water culture emission with energy of (3.35 ± 0.11)•108 quantum•cm2 and duration up to 4.96 s. Action of ethyl alcohol to culture also stimulated signals, but intensity of light emission was 3–4 times lower than under mechanical stimulation. For sure the given studies will permit not only to evaluate contribution of marine fungi into general bioluminescence of the sea, but as well to determine places of accumulation of opportunistic species in the sea.

First Time

Phoretic mites use bark beetles for transportation to new, suitable habitats. Some phoretic mites act as predators and parasitoids of the bark beetles’ immature stages, especially egg and early larval stages, and are potential agents for the biological control of scolytine forest pests. Mites live very frequently in relationships with other invertebrates. Many are found in association with various species of bark beetles. Here, a total of 41 specimens of different bark beetles of the genus Ips (Ips acuminatus, Ips sexdentatus and Ips typographus) were studied for presence, species composition, and abundance of phoretic mites. The beetles were collected on dead wood and parts of tree bark of Pinus nigra, Pinus sylvestris and Picea abies in the Black Sea Mountains in Kastamonu and Artin Province of Turkey. A total of nine mite species were found, including Dendrolaelaps quadrisetus, Ereynetes sp., Histiostoma piceae, Paraleius cf. leontonychus, Pleuronectocelaeno barbara., Proctolaelaps hystricoides, Schizostethus simulatrix, Trichouropoda lamellosa and Uroobovellaipidis. All species are identified for the first time within Turkish fauna.
