Change of intensity of a field of a bioluminescence in a night-time in the western part of the Black Sea is investigated. The differences in the dynamics of the field intensity of bioluminescence in the upper (0–35 m) and deep (≥35 m) layers. Methods of multivariate statistical analysis revealed that biolyuminestsenty are in space of several factors, among which are the biotic and abiotic. It is shown that the greatest influence on the frequency of increase and decrease of the intensity of the bioluminescence field affect biotic factors. Abiotic factors are less important in the circadian rhythm biolyuminestsentov.

Keywords: The Black Sea, bioluminescence field, water layers, factors, biolyuminestsenty.

The experiments were conducted to determine final selected temperature (FST) avoided temperatures by a graphicall method at Ceriodaphnia quadrangula (O.F. Müller, 1785) from the littoral of the Rybinsk reservoir during the vegetative season. The range of selected temperatures (17.4–26.5℃) which corresponds to optimum temperatures of growth and development of cladocerans in reservoirs, a temperature zone of normal vital ability (13.0–27.0℃), ranges of avoided temperatures (6.0–13.0℃ and >27.0℃) and lethal temperatures (<6.0 and >33.0℃) are revealed. The probable reasons and mechanisms of temperature responses of cladocerans are discussed.

Keywords: Ceriodaphnia quadrangula, thermal gradients, final temperature selection, avoided temperatures.

The Structure of Flagellar Apparatus of Bacteriovorous Flagellate Histiona aroides Pascher, 1943 (Jakobida Excavata).

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

e-mail: mylnikov@ibiw.yaroslavl.ru

The structure of flagellar apparatus of excavate flagellate Histiona aroides has been considered. Two naked flagella emerge from the bottom of ventral groove. The proximal part of the kinetosomes has osmiophilic cone. The posterior short flagellum bears the wide fold, which directs to the cell and contains striated material. The wide dorsal microtubular band begins close to the kinetosome of the anterior flagellum, the left and right bands each of which is divided into two bands and single microtubule begin close to the kinetosome of the posterior flagellum. The amorphous and striated fibrils accompany these bands. The left external band and multi-layer structure (band C) go into the epipodium. The microtubular bands reinforce the bottom of the ventral groove and external margin of the “sail”. Moreover, the vesicular nucleus, extrusomes, contractile vacuole and mitochondria with tubular cristae are visible on the cell sections. The resemblance of H. aroides with other jakobids and excavates is discussed.

Keywords: Histiona aroides, ultrastructure, flagellar apparatus, cytopharynx, Jakobida, Excavata.

Illustrated descriptions of two new free-living nematode species, found in the mangrove thicket in the estuary of rivers of Vietnam. Metachromadora (Metachromadoroides) orientalis sp. n. morphologically similar to M. (M.) zaixsi Pastor de Ward, 2004, but is longer and thicker tail, more forward position of vulva, other shape of amphidial fovea, larger basal bulb of pharynx, longer spicules and other arms of male tail. Terschellingia obesa sp. n. differs from T. supplementata Tchesunov, 1978 and T. elegans Gagarin, Nguyen Vu Thanh, 2003 by a thicker body, wider body at the level of cephalic setae and longer spicules. A key is given to determine valid species of the Metachromadora (Metachromadoroides).

Keywords: Vietnam, mangrove thicket, free-living nematode, Metachromadora (Metachromadoroides) orientalis sp. n., Terschellingia lutosa sp. n..

The total abundance of virioplankton and the total abundance of bacterioplankton were dtermined in two small rivers and in the large Sheksna River in April–October 2009–2011. A high positive correlation was found between the abundance of viruses and bacteria. The abundance of planktonic viruses in small rivers exceeded their abundance in the Sheksna River. In 2010 in all rivers with extremely high temperature of water of summer the abundance of planktonic viruses was significantly higher than in years with normal temperature of water of summer.

Keywords: viruses, bacteria, rivers.

Distribution of Еnergy Flow in Bottom Community Between Different Size Groups of Zoobenthos (by the Example of the Neva Bay).

Zoological Institute Russian Аcademy of Sciences, 199034 Sankt-Petersburg, Universitetskaya Embankment, 1, Russia

e-mail: alexeymaximov@mail.ru

The role of three size groups of metazoans (meio-, macro- and megabenthos) in bottom communities is estimated by the example of the Neva Bay. Meio- and megabenthos (large mollusks fam. Unionidae and Viviparidae) prevailed in total zoobenthos abundance and biomass respectively. Macrobenthos dominated in functional traits (production, respiration and energy flow) determining about 3/4 of benthic energy flow during the study period (2010–2011). The analysis of long-term data indicates that the ratio of size groups is not constant in time and larger animals (macro- and megabenthos) are characterized by more significant long-term variability. The necessity to distinguish megabenthos (>1 cm) as a distinct size category as in marine biology is substantiated.

Keywords: meiobenthos, macrobenthos, megabenthos, freshwater communities, Unionidae.

The peculiarities of distribution of sarin herring larvae Alosa braschnikowi sarensis in coastal and open areas of the south-western part of the Caspian Sea have been studied, based on materials of the ichtioplancton filming made in July–August 2010–2012. Three isolated accumulations of larvae were observed in the southwestern part of the Caspian Sea from year to year: one accumulation was found in the area of the Sara Demi-Island and Kura Spit, the second accumulation was found near islands of the Baku archipelago and Pirsagat cape, and the third accumulation was found in the Lenkoran region. It is supposed that these accumulations are the consequence of spawning of three independent spawning groups of sarin herring, which spawn in separate regions of the southwestern part of the Caspian Sea.

Keywords: sarin herring, larvae, distribution, density, population structure.

Dynamics of the Sodium and Potassium Contents in Plasma, Erythrocytes and Muscles of Freshwater Fishes under Effect of Combined Long-Term Stress.

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

e-mail: martem@ibiw.yaroslavl.ru

At the initial period of acute stress the concentration of sodium in plasma blood of roach and bream decreased sufficiently during several hours by 30 and 27%, respectively, creating the difference in osmotic concentration between cellular and extracellular liquid of an organism. Counteraction of hyponatremia and hypoosmolality was carried out due to intensive extraction of sodium and potassium ions from intracellular liquid due to intensifying of Na⁺-K⁺-2Cl⁻-cotransport system. As the result, the content of sodium and potassium in erythrocytes and muscles of fishes decreased to the minimum values. During acclimatization of fish to new conditions the ion concentration in plasma, erythrocytes and muscles stabilized at fixed resistant levels.

Keywords: roach, bream, plasma, erythrocytes, muscles, sodium, potassium.

e-mail: daniil@ibiw.yaroslavl.ru

The results of the studies on the effect of dexamethasone on oxidative processes in the immunocompetent organs (a liver, a kidney and a spleen) of sterlet Acipenser ruthenus are generalised. Fish respond to the effect of the stress hormone by activation of lipid peroxidation and the decrease in antioxidant activity. The dependence of changes of studied parameters indicators on features of the structural and functional organization of organs and the time of sampling after a hormone injection is shown.

Keywords: sterlet, dexamethasone, immunocompetent organs, lipid peroxidation, antioxidant activity.
