Abstract. This paper documents the picoplankton community's response to changes in oceanographic conditions period between October 2011 and September 2012 at two stations belonging South Adriatic Pit (SAP). The recorded data include abundance, composition, prokaryotic production rates bacterial metabolic capacity. sampling included an intense sea cooling with formation of exceptional, record-breaking dense water. We documented especially winter convection episode that completely diluted core...
Biochemical and fatty acid composition of the bivalve Arca noae were investigated in Mali Ston Bay relation to environmental conditions. Sampling was carried out monthly, from December 2001 November 2002. Wet shellfish meat consists on average 77.61% water 22.39% dry matter, while 89.04% organic 10.96% inorganic matter. PCA analysis identified temperature, nitrate, silicate, MICRO, Chl a salinity as most important factors influencing biochemical A. noae. An increase weight content observed...
The taxonomic composition and structure of a marine epilithic diatom community were sampled from the bottom two sites at monthly intervals January to December 2011 in small semi-enclosed oligotrophic Neum Bay Bosnia Herzegovina (Middle Adriatic). Altogether, 264 taxa (species infraspecific taxa) within 69 genera identified. Among them, 149 203 occurred samples shallow (0.5 m depth) deep (8 sites, respectively. distribution most diatoms was irregular high numbers sporadic found. SIMPER...
Abstract The Rogoznica Lake marine system is a small, karstic, naturally eutrophic and euxinic environment. Abundance temporal distribution of phytoplankton was investigated in relation to environmental conditions the period from 1998 2013. 36 determined diatoms contributed 90% total abundance. diatom composition characterized by low species diversity high single abundance (up 107 cells L -1 ). There were, on average, 2.6 per sample (maximum 14 sample) reflecting extreme conditions. Dominant...
The initial colonization of bacteria and diatoms on a immersed artificial substrate the development diatom assemblages in relation to physico-chemical parameters were investigated weekly basis at one station marine Lake Mrtvo More, South Croatia, from April October 2016. According TRIX trophic index, lake showed different character: (i) oligotrophic (at beginning end study), (ii) mesotrophic (the June mid-July), (iii) eutrophic July mid-September). Heterotrophic increased peak abundances...
Epilithic diatom community structures are compared among three locations of the eastern Adriatic Sea coast (Croatia), in presence two different invasive Caulerpa species, C. taxifolia and cylindracea, which have spread rapidly Mediterranean last decades. Forty samples were taken seasonally at sites (island Hvar, island Mljet, Dubrovnik) between November 2008 October 2010. Light electron microscopy examinations used for qualitative analysis. Altogether 310 epilithic taxa belonging to 65...
Blue Haslea species are marine benthic pennate diatoms able to synthesize a blue-green water-soluble pigment, like marennine produced by H. ostrearia Simonsen. New of synthetizing blue pigments were recently described (H. karadagensis, nusantara, provincialis and silbo). Their marennine-like have allelopathic, antioxidative, antiviral antibacterial properties, which been demonstrated in laboratory conditions. Marennine is also responsible for the greening oysters, example, Marennes Oléron...
Abstract Bearded horse mussel Modiolus barbatus and Noah’s ark shell Arca noae are a species of interest for the diversifying shellfish aquaculture on south-eastern coast Adriatic. In this study, oxygen consumption (OC), total ammonia excretion (TAM) clearance rate (CR) responses to changes in seawater salinity (37, 30, 25 20) were investigated laboratory. There is statistically significant influence TAM shell, while time exposure different salinities significantly correlated by bearded...
Bearded horse mussel and Noah's ark shell are sometimes observed to live together in groups.Oxygen consumption, ammonia excretion clearance rate were investigated on these species under laboratory conditions considering different size of individuals divided into three groups (less than 25 mm; 50 mm larger mm).Body both significantly influenced oxygen the shell.In species, respiration decreased with body while increased size.For smaller mm, atomic ratio between consumption ammonium i.e.O:N...
In this study, the diatoms of three alternative habitats (epilithon, epiphyton and artificial sub-strate) were compared to understand differences in composition on natural sub-strates. For purpose, samples collected weekly between 11th August 2nd Septem-ber 2016 at a sampling site shallow marine lake, Mrtvo More (Dead Sea) Lokrum Island near Dubrovnik (South Adriatic, Croatia). addition detailed light microscopic analysis, ultrastructural analysis benthic from Lake was performed for first...
