Today's citizens of island Vrgada are not, as was pressumed, descendants of island'sprecitizens which in the mid of the 10th century started with settling down in the island. Thedescendants of ...Vrgada's precitizens mostly become deserted by pestilence epidemic during theyears 1631/32. Today's citizens are descendants of newcomers which in the mid of 17th century come to Vrgada, mostly as refugee families from the West Bosnia, and in minor from the near settlements on the coast and on the islands.
Aquaculture provides more than 50% of all seafood for human consumption. This important industrial sector is already under pressure from climate-change-induced shifts in water column temperature, ...nutrient loads, precipitation patterns, microbial community composition, and ocean acidification, all affecting fish welfare. Disease-related risks are also shifting with important implications for risk from vibriosis, a disease that can lead to massive economic losses. Adaptation to these pressures pose numerous challenges for aquaculture producers, policy makers, and researchers. The dataset AqADAPT aims to help the development of management and adaptation tools by providing (i) measurements of physicochemical (temperature, salinity, total dissolved solids, pH, dissolved oxygen, conductivity, transparency, total nitrogen, ammonia, nitrate, nitrite, total phosphorus, total particulate matter, particulate organic matter, and particulate inorganic matter) and microbiological (heterotrophic (total) bacteria, fecal indicators, and Vibrio abundance) parameters of seawater and (ii) biochemical determination of culturable bacteria in two locations near floating cage fish farms in the Adriatic Sea. Water sampling was conducted seasonally in two fish farms (Cres and Vrgada) and corresponding reference (control) sites between 2019 and 2021 of four vertical layers for a total of 108 observations: the surface, 6 m, 12 m, and the bottom.
•Geochemical and foraminiferal analyses of fish farm sediments near Vrgada Island.•Elemental concentrations show only natural elemental variations.•Phosphorus concentration is elevated below the cage ...due to fish pellets.•Foraminiferal assemblages influenced by the substrate and phosphorus content.•Results point to negligible farming influence and stable environmental conditions.
Effects on sediments of fish farming activity near Vrgada Island was analysed through living and total foraminiferal assemblages and concentration of major, minor and trace elements from three sediment cores. Elemental concentrations of sediments are in accordance with carbonate characteristics of the surrounding area and show mostly natural element variations between sampling locations and throughout the cores, with no significant increases due to fish farming activity. Only phosphorus concentration shows elevate values below the fish cage, assigned to fish pellets. Foraminiferal communities are dominated by epifaunal and stress tolerant species, while diversity indices point to normal marine conditions. The type of substrate and phosphorus content in sediments principally influence foraminiferal community composition, while other elemental concentrations have no perceptible effect on the assemblages. Some foraminiferal species Ammoniatepida, Ammoniabeccarii, Elphidiumcrispum, Elphidiummacellum and genus Haynesina are confirmed to be tolerant to elevated nutrient (phosphorus) content, while Ammonia parkinsoniana shows sensitivity to pollution. Postmortem processes cause decrease of foraminiferal density and species richness with core depth. All results point to negligible influence of fish farming and relatively stable environmental conditions at all sampling locations.
Vrgada Island is situated in the central part of the eastern Adriatic coast. Upper Cretaceous limestones crop out on the surface and Pleistocene sediments cover them in some parts of the island. In ...this study we focus on a coastal cliff elongated in the N – S direction, situated in the northern part of the island. Aeolian-alluvial deposits, which are 12.5 m thick have been analysed. Three different facies in this succession are described. Lowermost facies A has a strong aeolian influence marked by increased silt and clay percentage and was deposited during colder climate conditions. Structureless sand in facies B was deposited from dense, cold water formed by melting snow and ice from the nearby Dinaric mountains. Bioturbated sandy facies C was probably formed during warmer climate. Unusually high percentage of augite in the lowermost part of facies A can be explained by volcanic dust input, most likely from the Roman or Campanian volcanoes in Italy. Combination of surface textures on quartz grains detected from SEM photographs indicate a short transport of sediment, no matter which mechanism) was dominant. Age correlation of possible tephra horizon from Vrgada island with confirmed tephra from Susak Island and dated ice/snow melting period from nearby mountains points to Upper Pleistocene age of sediments, most likely MIS 3 and MIS 2. The sediments from the Vrgada Island represent a transitional zone between the north Adriatic islands, where aeolian sediments dominate and the South - Eastern Adriatic archipelago, where mixed alluvial and aeolian sediments were observed.
Erosive coastal cliffs formed in soft-rocks sediments along the generally carbonaceous Eastern Adriatic are a rare feature. The one from the Vrgada Island gave rise to the idea that local seabed ...surface sediment may reflect the composition of the cliff sediment. First results of sedimentological analyses showed that sediment samples collected on both sides of the cliff contain material eroded mostly from the eastern side of the cliff. Subsequent longshore drift caused by dominant waves likely sort fallen material, transporting its finer fractions to the northern side and further into the sea.
Floristic researches of the 14 islets and reefs near Vrgada Island (Zadar archipelago, eastern Adriatic) were conducted in the period from 2009 and the spring of 2010. For the 13 islets and reefs, ...264 vascular plant taxa were recorded and classified in 184 genera and 63 families. No taxa were recorded for one reef. The domination of therophytes (42.42 %) and plants of the Mediterranean floral element (49.62 %) confirmed the Mediterranean character of the islets' flora.

475 vascular plant taxa (441 species and 34 subspecies; 300 genera and 73 families) were recorded in the flora of the island of Vrgada and the three nearby islets (Artina, Obrovanj and Rakita), as ...well as two reefs, according to the literature data and our research during 2003-04. In the crops, 108 taxa have been registered which have been included in the analyses. A taxonomical analysis was made, as well as an analysis of life forms and floral elements.
