| Researches in the bioluminescence field vertical structure, amplitude characteristics and spatial distribution in the Black Sea have been conducted in IBSS, NAS of Ukraine, from up to the present time. Enough evidencies are available to testify dramatic changes in different Black sea ecosystem components including bioluminescence field parameters, which took place last decades. But still there is no direct answer to the question about the reasons for such transformations, as variability of the Black Sea biophysical (bioluminescence) and biological characteristics at the climatic time scales, i.e. at the scale of decade periods are not sufficiently studied now. The most pronounced changes in vertical structure of the bioluminescence field are observed in... |

| Представлены результаты исследования поля биолюминесценции, гидрологических и гидрохимических характеристик Чёрного моря. Показано, что зоны повышенной интенсивности поля биолюминесценции и концентраций планктона в Чёрном море соответствуют положению 9-ти квазистационарных зон антициклонических вихрей, располагающихся над континентальным склоном. В этих районах происходит заглубление поверхностных аэрированных вод до глубины 100 – 120 м, что создаёт благоприятные условия для развития гидробионтов, в частности, нагула многих промысловых рыб. |

| Luminous dinoflagellates biomass seasonal dynamics as well as bioluminescence field vertical structure changeability during the year cycle (2008–2009) near the Sevastopol was studied. Two evident peaks during the cold (February) and warm (July–August) periods were revealed, which was connected with differences in development level and phytoplankton vertical distribution, which were stipulated in turn, by water hydrostructure peculiarities in the natural stratification layers. “Winter” bioluminescence maximum in the surface layer was stipulated by the development of C. fusus; P. divergens; P. oblongum mainly, with the cells volume, maximal in the year. The second one, located in the thermocline layer and lower, was formed, mainly, at the expense of C. fusus... |

| The deep-sea benthic ecosystems of the French Kerguelen exclusive economic zone remain poorly understood. To address benthic conservation issues, the authors recently contributed expert knowledge to guide the recent extension of the Marine Reserve of the ‘Terres australes françaises’. In this new study, we propose a benthic ecoregionalisation of the northern Kerguelen Plateau based on a measurable and repeatable methodology that relies on the generalised dissimilarity modelling technique. Data of macro-epibenthic invertebrate species from the POKER 2 (2010) fish stock assessment survey have been used to compute the models. Our results allow us (i) to characterise and map benthic landscape units based on assemblages of marine invertebrates pooled by taxa... |

| This article describes a method for high-throughput competition assays using a bioluminescent strain of L. monocytogenes. This method is based on the use of the luminescent indicator strain L. monocytogenes EGDelux. The luminescence of this strain is correlated to growth, which make it suitable to monitor the growth of L. monocytogenes in mixed cultures. To this aim, luminescence kinetics were converted into a single numerical value, called the Luminescence Disturbance Indicator (LDI), which takes into account growth inhibition phenomena resulting in latency increase, decrease in the luminescence rate, or reduction of the maximum luminescence. The LDI allows to automatically and simultaneously handle multiple competition assays which are required for... |

| An Acoustic Doppler Current Profiler (ADCP) was moored at the deep-sea site of the ANTARES neutrino telescope near Toulon, France, thus providing a unique opportunity to compare high-resolution acoustic and optical observations between 70 and 170 m above the sea bed at 2475 m. The ADCP measured downward vertical currents of magnitudes up to 0.03 m s(-1) in late winter and early spring 2006. In the same period, observations were made of enhanced levels of acoustic reflection, interpreted as suspended particles including zooplankton, by a factor of about 10 and of horizontal currents reaching 0.35 m s(-1). These observations coincided with high light levels detected by the telescope, interpreted as increased bioluminescence. During winter 2006 deep... |

| Data collected during cruises of the Former Soviet Union (in 1963-1989) and the British Atlantic meridional transect program (in 1995-1999) were used to analyse macroscale patterns in phyto- and zooplankton biomass, size structure, species diversity, chlorophyll a, and plankton bioluminescence in the macroscale anticyclonic gyre of the South Atlantic Ocean. The spatial pattern of bioluminescence intensity was in good agreement with that of remotely sensed (CZCS) chlorophyll a, phosphate, salinity, and copepod species diversity index distributions especially in terms of geographic inclinations of the isolines, both associated with the north-westward pattern off the South equatorial current. Among the 416 copepod species recorded in samples, 51 species were... |
