The Northern Adriatic is a dynamic and the most productive part of Sea. phytoplankton is, as many studies in this area showed, under heavy influence freshwater inputs anthropogenic pressures. Cluster analysis more than 20 year data set across steep spatio-temporal, ecological gradients on longitudinal transect northern Adriatic, allowed us to identify significant reoccurring species assemblages. Those clusters show stable seasonality relation environmental conditions are presumed be...
Implementation of DNA metabarcoding for diatoms environmental monitoring is now moving from a research to an operational phase, requiring rigorous guidelines and standards. In particular, the first steps diatom process, which consist sampling storage, have been addressed in various ways scientific pilot studies need be rationalised. The objective this study was compare three currently applied preservation protocols through different storage durations (ranging one day year) phytobenthos...
The northern Adriatic is characterised as the coldest and most productive marine area of Mediterranean, which due to high nutrient levels introduced by river discharges, largest Italian Po River (at same time also freshwater input into Mediterranean). a very shallow ecosystem with ocean current patterns that result in long retention times plankton area. phytoplankton biodiversity abundance are well-studied, through many scientific long-term monitoring reports. These datasets were based on...
Seasonal changes of microbial abundance and associated extracellular enzymatic activity in marine snow seawater were studied the northern Adriatic during a three-year period. Marine was present entire period investigation, although higher concentrations summer than winter. Microorganisms densely colonized aggregate-associated substantially (up to 105 times) seawater. Alkaline phosphatase (APA) aminopeptidase showed seasonal variations with values late spring-summer autumn-winter, probably...
The temperature increase in oceans reflects on marine ecosystem functioning and surely has consequences the carbon cycle sequestration. In this study, we examined dissolved lipid, lipid classes organic (DOC) production northern Adriatic Sea, isolated diatom Chaetoceros pseudocurvisetus batch cultures grown a wide range (10–30 °C) contrasting nutrient regimes, phosphorus (P)-depleted P-replete conditions. Additionally, lipids DOC were analyzed (NA) two stations characterized with different P...
Chaetoceros peruvianus is a marine diatom species with circumglobal distribution. While frequently observed, it appears never to dominate the phytoplankton community hence can be characterized as rather opportunistic, generalistic species. Here we present ecological interpretations from long-term data set on microphytoplankton in northern Adriatic Sea, where abundancies and relative contributions of C. were observed along steep gradients. Limited supply dissolved inorganic phosphate was...
Plankton studies serve as a basis for marine ecosystem research, but knowledge of plankton is still incomplete due to its extreme taxonomic and functional complexity. The application metabarcoding very valuable the characterisation community. community Southern Adriatic subject strong environmental fluctuations changes, which underlines need frequent, reliable comprehensive plankton. aim this study was determine composition seasonal distribution eukaryotic in Adriatic. samples were collected...
Abstract Marine microbial communities form the basis for functioning of marine ecosystems and conservation biodiversity. With application metagenomics metatranscriptomics in environmental studies, significant progress has been made analysing as a whole. These molecular techniques are highly dependent on reliable, well-characterised, comprehensive taxonomically diverse sequenced reference transcriptomes organisms. Here we present set 12 individual transcriptome assemblies derived from 6...
The hemocytes/coelomocytes DNA content in five selected marine invertebrates (sea mouse Aphrodita aculeata, spiny crab Maja crispata, sea star Echinaster sepositus, urchin Paracentrotus lividus, and tunicate Phallusia mammillata) was investigated by flow cytometry. cell cycle analyses identified coelomocytes as proliferating cells revealed that hemocytes complete their division the hemolymph coelom, respectively. genome sizes of are reported for first time. diploid (2C) A. aculeate 1.24 pg,...
The northern Adriatic is highly productive and shallow area characterized by numerous spatio-temporal gradients (e.g. nutrients, salinity, temperature). It strongly influenced freshwater inputs, mainly from Po river. Its current systems as well river, generates of phosphate availability with an expressed N/P imbalance limitation. A number recent studies these major factors affecting abundance composition microphytoplankton communities. Focus this study on two Leptocylindrus species, aporus...
To study zooplankton–phytoplankton relationships in the diatom-dominated plankton communities of northern Adriatic we performed feeding experiments with diatoms and zoea I larvae brachyuran Xantho poressa. We found that X. poressa feed on different forms (centric, pennate, colony forming, single celled, or without setae) size classes. In a laboratory setup, presented zoeas mix diatom species similar to observed during blooms regularly Adriatic. report grazing activity resulted decrease...
Abstract Marine life is threatened by global warming and its indirect consequences, which include, among others, increased stratification leading to phosphorus (P) nitrogen depletion in the upper water column. Phosphorus plays a key role all biochemical systems; storage of metabolic energy, formation genetic material, subcellular compartmentalization. Our multi‐year study lipid biogeochemistry northern Adriatic (Mediterranean), becoming warmer nutrient‐poorer, particularly regarding P, has...
Environmental contamination includes a mixture of organic substances that can have detrimental effects on marine organisms and should be evaluated in the quality risk assessment investigated areas. Marine areas selected for this study are protected area, mariculture shipyard an industrial area. Based toxicity seawater extracts these were classified as undisturbed reference area (S1), with low anthropogenic impact (S2), potentially endangered (S3) high (S4) respectively. The mixtures present...
