The remains of the sewn boat known as Poreč 1, dating to the beginning of the 1st century BC, which was discovered, documented in situ and recovered in 2020, and then re-examined in 2021 prior to conservation treatment, adds new information to the already rich archaeological corpus of sewn boats from the northern Adriatic, providing valuable new data for defining local shipbuilding traditions. This article presents the results of the recent archaeological research, interdisciplinary study and preliminary reconstruction. [ABSTRACT FROM AUTHOR]

In the Mediterranean Sea, pelagic longline fisheries, targeting tuna and swordfish, have contributed significantly to the bycatch of threatened chondrichthyan species, such as blue shark (Prionace glauca). The Mediterranean blue shark population is assessed as critically endangered, making a timely implementation of mitigation measures crucial. A comprehensive understanding of blue shark habitat use dynamics is essential for deriving appropriate mitigation measures. This study aimed at evaluating vertical movement behaviour and investigating factors potentially influencing the movements of blue sharks in the Mediterranean Sea. Twenty-six blue sharks, bycaught in a longline fishery in the southern Adriatic, were tagged with pop-up satellite archival tags. Analysis of data from thirteen recovered tags revealed a distinctive diel movement pattern. Blue sharks used shallower waters during the night and deeper waters during the day, characterised by steep ascents and descents during sunset and sunrise, respectively. In addition, lunar phases were also influencing the depth of blue shark movements, with sharks using deeper waters right before and during full-moon. Shark size, salinity, currents, spatial location and time of the year were additional factors influencing blue shark depth use. The observed tendency of blue sharks to use deeper areas at daytime and prior and during the full moon period offers possibilities to develop and test bycatch mitigation strategies. Aligning longline fishing schedules and fishing depths with blue shark behaviour during the fishing seasons could hold promise to effectively reduce spatio-temporal overlap between fishing and blue shark distribution and may ultimately decrease the bycatch impact of the fishery.

Based on situational crisis communication theory, this study designs a research framework to identify differences in crisis communication practises on beach hotel websites in different Adriatic countries and between three consecutive summer seasons due to the COVID-19 pandemic. A qualitative inductive content analysis of official pandemic-related guidelines/recommendations from national and international competent organizations was carried out. Subsequently, an overlooked repeated measures design with deductive quantitative content analysis of crisis communications on hotel websites during the three summer seasons was conducted. Employing the McNemar test, the Cochran's Q-test and Friedman test with post-hoc comparisons, it was discovered that (1) beside the bolstering strategy, the new 'ignore strategy' of crisis communication was also identified, which has many implications, (2) communication of anti-COVID-19 measures is statistically significant and relatively strongly associated with the country in which hotels are located, and (3) the number of different announcements on anti-COVID-19 measures is significantly different only between two seasons.

Simple Summary: The present report describes the first molecular detection of a gammacoronavirus in a free-ranging striped dolphin coinfected with cetacean morbillivirus and found stranded on the Croatian coastline in 2022. The virus was detected in a heart sample and appeared different from previously identified cetacean gammacoronaviruses. This finding underscores the necessity of including this pathogen into routine diagnostics for stranded dolphins to gather important epidemiological data on coronavirus prevalence and its potential role in causing disease. This case report presents the first molecular identification of a gammacoronavirus in a free-ranging striped dolphin (Stenella coeruleoalba) that was found stranded along the Croatian coastline in 2022. The dolphin exhibited a concurrent infection with cetacean morbillivirus. The gammacoronavirus strain was amplified and sequenced from heart tissue imprinted on an FTA®card, revealing a notable genetic distance (approximately 8%) from previously characterized cetacean gammacoronaviruses. This finding highlights the importance of including gammacoronaviruses in routine diagnostics for stranded dolphins to gather epidemiological data on their prevalence and potential role in causing disease in cetaceans. This study sets the premises for a further understanding of the diversity and distribution of gammacoronaviruses in marine mammals and highlights the necessity for ongoing surveillance of emerging infectious diseases in wild populations.

This study gives the first data on the body and beak morphometric characteristics, age, and genetic structure of neon flying squid, a rarely caught cephalopod in the Adriatic Sea. We identified specimens as recently resurrected Ommastrephes caroli species using two mitochondrial markers, 16S ribosomal RNA gene and cytochrome c oxidase subunit I gene. Overall, 23 juveniles (3 females, 3 males, and 17 unsexed), with a dorsal mantle range of 65–152 mm, were caught in September 2020 in the waters of the Korčula Channel, island of Palagruža, and island of Jabuka, thus providing the most abundant sample of this species in the Mediterranean waters. The length–weight relationship showed an isometric growth. The results of the beak/length regressions suggest hood length is a useful characteristic for biomass estimation studies, as it showed a good linear fit to the dorsal mantle length. Statolith growth increments were easily visible and statolith microstructure analysis was successfully used to determine the age of 22 individuals. The estimated age ranged from 36 to 64 days (mean = 48 days). The back-calculation analysis showed that the squid hatched during July and August 2020, indicating that O. caroli spawns during the warmer, summertime period. Considering the size and age of the caught individuals, the Adriatic Sea could represent a potential feeding ground for this species. The genetic structure analyses indicate the existence of separate Atlantic and Mediterranean/Adriatic subclusters; however, this warrants further investigation. [ABSTRACT FROM AUTHOR]

We present the first evaluation of the wind field from the ensemble of kilometer-scale simulations from the CORDEX-Flagship Pilot Study on convection, with focus on the Adriatic region. Kilometer-scale climate models, also known as convection-permitting models (CPMs), produce a good representation of small-scale topographic features and consequently a more detailed depiction of dynamical and thermal circulations. These enable a reliable view of climate characteristics of the wind field, especially in coastal regions and over complex terrain, such as the Adriatic region. We investigate the (potential) added value introduced by CPMs compared to classical "cumulus-parametrized" regional climate models (RCMs), reanalysis and station observations. For this purpose, wind components at 10 m level are used at 3-hourly frequency. All simulations cover a 10-year period, extending from 2000 to 2009. In terms of the standard statistical parameters such as correlation coefficient and temporal standard deviation, CPMs are very dependent on their parent RCM performance. However, the orographic forcing emphasizes the potential added value and CPMs contain some fine spatial scale variability (i.e., stronger extremes by 25% and more accurate wind direction) that is absent in coarser RCMs and reanalysis. The potential added value is higher in the cold season compared to the warm season due to the proportion of severe wind events. CPMs reproduce well the typical wind regimes along the Adriatic coast, namely Bora and Sirocco. The benefit of using CPMs is especially pronounced in simulating Bora maximum wind speeds in northern Adriatic and Sirocco frequencies in southern Adriatic. Based on our overall analysis, we conclude that CPMs provide added value compared to coarser models, especially in the complex coastal terrain. [ABSTRACT FROM AUTHOR]

This chapter relates post-1918 Italy to the collapse of the Habsburg Empire and the ascent of the successor states, and analyses, from the Trieste's vantage point, fascist projects, practices and networks of 'empire' in the Adriatic Sea, in Mitteleuropa and in the Balkans between 1918 and 1938. It focuses on three connected aspects. Firstly, the northern Adriatic was the first setting of the ascent of squadrismo, a model of violent action against 'enemies within' then replicated elsewhere. Secondly, Italian nationalism and imperialism aimed to reconfigure the post-Habsburg economic space and to reconnect the Adriatic with Central and Balkan Europe. Thirdly, Italian nationalist (then Fascist) élites from Trieste played a critical role, by boosting processes of empire-building and defending Austria vis-à-vis the prospects of Anschluss. In sum, the Habsburg legacies kept on shaping the dynamics of Italianization and fascistization in northern Adriatic and on feeding the search for Italy's informal empire in Central and Southeastern Europe.

The fish species undergo diel and seasonal changes in coastal (littoral) ocean zones. Many factors affect these seasonal and diel patterns, thus it is difficult to determine which are the most important. Concerning the Adriatic Sea, studies on the temporal changes of fish communities are rare. Therefore, the primary aim of this study was to evaluate, in terms of abundance, diversity and species composition, the diel and seasonal changes in a one-year cycle of the fish community living in the infralittoral zone of the Eastern Central Adriatic and the main drivers affecting them. This study revealed the presence of a very rich and diverse community in the coastal zone of the Eastern Central Adriatic with a total of 63 identified fish species. The results showed that the differences in fish assemblage were more strongly influenced by seasonal variations rather than diurnal variations. The primary environmental factor that drives fish to undertake seasonal variations is water temperature. Considering that many species are important commercial species, especially for small scale fisheries, and taking into account future climate-driven changes that would affect the seasonality of the target species, it is essential that future management will be tailored accordingly and in due time.

Diatoms are one of the most important phytoplankton groups in the world's oceans. There are responsible for up to 40% of the photosynthetic activity in the Ocean, and they play an important role in the silicon and carbon cycles by decoupling carbon from atmospheric interactions through sinking and export. These processes are strongly influenced by the taxonomic composition of diatom assemblages. Traditionally, these have been assessed using microscopy, which in some cases is not reliable or reproducible. Next-generation sequencing enabled us to study diversity in a high-throughput manner and uncover new distribution patterns and diversity. However, phylogenetic markers used for this purpose, such as various 18S rDNA regions, are often insufficient because they cannot distinguish between some taxa. In this work, we demonstrate the performance of the chloroplast-encoded rbcL marker for metabarcoding marine diatoms compared to microscopy and 18S-V9 metabarcoding using a series of monthly samples from the Gulf of Trieste (GoT), northern Adriatic Sea. We demonstrate that rbcL is able to detect more taxa compared to 18S-V9 metabarcoding or microscopy, while the overall structure of the diatom assemblage was comparable to the other two methods with some variations, that were taxon dependent. In total, 6 new genera and 22 new diatom species for the study region were identified. We were able to spot misidentification of genera obtained with microscopy such as Pseudo-nitzschia galaxiae, which was mistaken for Cylindrotheca closterium, as well as genera that were completely overlooked, such as Minidiscus and several genera from the Cymatosiraceae family. Furthermore, on the example of two well-studied genera in the region, namely Chaetoceros and particularly Pseudo-nitzschia, we show how the rbcL method can be used to infer even deeper phylogenetic and ecologically significant differences at the species population level. Despite a very thorough community analysis obtained by rbcL the incompleteness of reference databases was still evident, and we shed light on possible improvements. Our work has further implications for studies dealing with taxa distribution and population structure, as well as carbon and silica flux models and networks. [ABSTRACT FROM AUTHOR]

This overview presents the different water masses present in the various primary and secondary marine regions of the Mediterranean Sea and Black Sea, providing information on their main physical characteristics (i.e., temperature, salinity, density), the water depths at which they have been observed and the processes involved in their formation. There is a characteristic difference in the overall hydrology of the Mediterranean Sea compared to the Black Sea, in terms of the number and characteristics of water masses and their formation processes, although they form a single (integrated) marine system. This difference is explained by the limited communication between the two seas through the Sea of Marmara and its straits (the Dardanelles and Bosporus) and by the fact that the Mediterranean Sea is a condensation basin while the Black Sea is a dilution basin; therefore, the deficit of water in the former is compensated by the inflow of Atlantic waters, while the surplus in the latter outflows to the Aegean Sea. In total, 21 different water masses have been identified in the Mediterranean Sea (excluding the Straits of Gibraltar and the Sea of Marmara) compared to the 5 water masses identified in the Black Sea (excluding the Sea of Azov). This large number of water masses is attributed to coastal morphology (i.e., presence of straits) and submarine relief (i.e., deep basin separated by shallow sills) and different formation processes.

In this article, we have analysed how natural features influenced the emergence of maritime pilgrimages in the Eastern Adriatic (three sites in Croatia and one in Montenegro). All researched locations are insular and dedicated to the Virgin Mary (Madonna). We applied a diverse methodology, including flying a drone and completing fieldwork and archival work studying old maps and documents. We believe that the geography of pilgrimages in these sites reflects the relational interaction between the religious practices of the local communities, mostly fisherman, and their lived environment. We argue that all four locations of the churches and sites of pilgrimage were, at least partially, determined by natural features of their environment, i.e. a safe harbour and a site protected from winds, located within fisherman communities living space, etc. Because of these environmental determinants, the local communities created their pilgrimage geography with ritualistic and religious pilgrimage practices and folklore.

In this article, we argue that the different ritual structures of maritime pilgrimages result from the different historical backgrounds of each site. We have focused on two maritime pilgrimage sites in the Adriatic Sea: Nin, in contemporary Croatia (Northern Dalmatia), and Perast, in contemporary Montenegro (Kotor Bay). We compared these two locations and maritime pilgrimage processions because they have similar historical backgrounds (both were under Venice's significant influence), and comparable boat processions with similar structural elements. We concluded that multilayered customs, consisting of diverse popular traditions, were fused in these pilgrimages through ecclesiastical (para)liturgical processions. Based on material presented in this article, we concluded that the Nin and Perast elites drew on local traditions and developed maritime pilgrimage boat processions in order to draw out their political, religious, social, and economic potentials.

This paper describes the first record of the critically endangered gravid female spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the northern Mediterranean and simultaneously the only record of the species in this century for the Adriatic Sea. The female (173 cm disc width and 43.25 kg total weight) was captured at c. 200 m, off Vlorë in the southern Adriatic Sea off Albania on 12 May 2022. Upon necropsy, seven near‐term foetuses (mean 328 ± 6.47 mm disc width and mean 355 ± 20.06 g in total weight) were transported for further in‐vitro incubation. These results represent the deepest capture for the species, as well as the largest litter size and largest size at birth in the Mediterranean Sea, which indicates the need for further research.

Tremoctopods are epipelagic argonautoid octopods characterized by their expanded dorsal webs and strong sexual size dimorphism, with dwarfed males. The scarcity of taxonomic features attributed to this genus presents a challenge, and there is growing evidence of species misidentification in Tremoctopus genus on a molecular level. In this study, we investigated four female specimens of blanket octopus Tremoctopus violaceus caught by purse seine fishing in the Central Eastern Adriatic Sea in 2019. Individuals had smooth, firm and muscular bodies, dark bluish purple on the dorsal and iridescent silvery on the ventral side, with dorsal mantle lengths of 113, 82, 80 and 78 mm. The constructed phylogenetic trees based on the 16S ribosomal RNA and cytochrome c oxidase subunit I sequences of investigated Adriatic specimens and publicly available sequences showed strong support for the T. violaceus clade, consisting of individuals collected from the Adriatic Sea, Mediterranean Sea and Atlantic Ocean, with the exclusion of Indo-Pacific clade most probably corresponding to T. gracilis. To fully understand the life-history traits of Tremoctopus species, future research should focus on DNA-based methods for correct species identification combined with morphological characters, geographic distribution and ecological information.

Following the general approach to pilgrimage as established by anthropologists and other scientists, the paper analyses the pilgrimage in Nin to Our Lady of Zečevo. More specifically, this pilgrimage will be observed as a maritime pilgrimage, following relevant recent research. Based on the oral story about the apparition of Virgin Mary to a widow, the statue of Mary is transported from Nin in a boat procession via sea to a mediaeval church on the nearby uninhabited island of Zečevo. Pilgrimage practices include many sensorial and symbolic practices, so it will be analysed from several points of view and more than one theoretical approach, including the relational approach and mobility turn, applied also to maritime pilgrimage with a reflection on influence of tourism on pilgrimage activities, especially in the Mediterranean. The paper relies on the field research from 2020–2023 in Nin near Zadar in Croatia which has been supported in part by the Croatian Science Foundation under the project 'PILGRIMAR' (UIP-2019-04-8226).

This short piece comments on the articles presented in the forum on Adriatic tourism and their analyses of competing historical claims to "our Adriatic." The comment focuses on questions raised about ownership of the sea and the Adriatic's borders of belonging. While sovereignty over areas of the Adriatic has proven an enduring diplomatic issue in both the twentieth and twenty-first centuries, the forum authors instead consider claims by different types of actors: tourists (particularly Czech tourists who claimed a special relationship between Czechs and their South Slav "brothers"); investors in hotels and related infrastructure; socialist Yugoslav tourism planners; and environmentalists concerned with issues of pollution. In tracing out tensions in the agendas of hosts and visitors, as well as planners and scientists, the forum's essays measure and map the socio-ecological metabolism of the modern eastern Adriatic.

Croatia's coast located on the eastern Adriatic is rich with small gravel beaches with limited fetch. This leads to a specific low-energetic wave climate compared to most other beaches, while their gravel composition makes them unique. Most management of these beaches is performed without understanding the sediment transport occurring on the beaches. XBeach-Gravel is a numerical model capable of simulating bed-level change on gravel beaches, but lacks validation in the case of low significant wave height (under 2.5 m) and low peak periods (under 6 s), conditions that are present on the eastern Adriatic. Based on measurements performed in both laboratory conditions in a water canal in Hannover and actual storm wave conditions on Ploče beach, calibration of the model is performed. Model results are compared between laboratory conditions and field conditions for comparable wave conditions. XBeach-Gravel can simulate low-energetic events resulting in berm formation and berm buildup with a high Brier skill score if calibrated. Simulation of laboratory conditions requires high transport coefficient values and shows more sediment transport than similar wave conditions in the field. Calibration for field conditions is dependent on geodetic survey data capable of isolating wave events with dominant cross-shore transport, but once calibrated, XBeach-Gravel can achieve good to excellent Brier skill score values in simulating sediment change in low-energetic wave conditions on the eastern Adriatic.

In 1984-1986, Zvonimir Kralj, diver and keeper of the Piran Aquarium, recovered the Enigma cipher machine with codebook and several other items from the wreck of the German minesweeper R 15 sunk off the west coast of Istria between Savudrija and Umag. The article describes and defines the device and outlines the technical characteristics of the minesweeper of the 6th Minesweeper Flotilla (6. Räumbootsflottille) of the German Kriegsmarine, which was hit by the British torpedo boat MTB 409 on the night of April 16-17 1945, and sank about 3 nautical miles northwest of Umag. An examination of the preserved parts of the cipher machine revealed that it was a naval Enigma M4 with four rotors and a reflector C. An X-ray microtomography showed the serial number of the machine M 15648 and the last configuration, left to right: C/γ (Gamma), III, VI, IV. The external position of the Gamma rotor (»P«) indicates that the Enigma was not set in a mode compatible with the M3 model, which corresponds to the cipher keys for the last two months of the war.

The experience of Timoleon of Corinth as ruler of Syracuse is noteworthy of fuller examination. Even if Timoleon promoted an anti-tyrannical and democratic polis, he pursued the legacy of Dionysian policy with particular interest with Adriatic and Ionian areas. He also maintained close relations with Macedonian king Philip. Coinages and heroic worship posthumously assigned to Corinthian strategos show typical developments which are latter remarked in Hellenistic kingdoms, as far as concerns the idea of divine kingship as a legitimacy of royal power. All this ascertained, Timoleon's rule is not just an interlude between the Dionysii and the newly established tyranny of Agathokles, but a defining moment in this political and institutional organization of the Greek world.

The excavation of Crno Vrilo site (Zadar, Dalmatia, Croatia), carried out by B. Marijanović, has unearthed the vestiges of an Early Neolithic village dating back to ca. 5800–5600 cal BC. The lithic assemblage, with more than 4000 pieces, represents the biggest Impressed Ware assemblage of littoral Croatia. Lithic production at Crno Vrilo is characterised by the pressure Blade flaking on high-quality exogenous cherts (Gargano, southern Italy) reflecting important socio-economic and technical aspects that are specific to the Neolithic. The presence of some débitage elements such as flakes, debris, cortical and technological pieces indicates that standard pressure flaking occured at the site, while the presence of large Blades (with widths exceeding 20 mm) suggests production by lever pressure, a technique that required specialized knowledge and equipment. This article questions whether the lever pressure technique was used in the production of large Blades and examines the status of these Blades in the Crno Vrilo lithic assemblage by examining their technological and functional aspects.

The fish species undergo diel and seasonal changes in coastal (littoral) ocean zones. Many factors affect these seasonal and diel patterns, thus it is difficult to determine which are the most important. Concerning the Adriatic Sea, studies on the temporal changes of fish communities are rare. Therefore, the primary aim of this study was to evaluate, in terms of abundance, diversity and species composition, the diel and seasonal changes in a one-year cycle of the fish community living in the infralittoral zone of the Eastern Central Adriatic and the main drivers affecting them. This study revealed the presence of a very rich and diverse community in the coastal zone of the Eastern Central Adriatic with a total of 63 identified fish species. The results showed that the differences in fish assemblage were more strongly influenced by seasonal variations rather than diurnal variations. The primary environmental factor that drives fish to undertake seasonal variations is water temperature. Considering that many species are important commercial species, especially for small scale fisheries, and taking into account future climate-driven changes that would affect the seasonality of the target species, it is essential that future management will be tailored accordingly and in due time.

Historically, two angel shark species, common angel shark Squatina squatina and smoothback angel shark Squatina oculata, were common in the upper continental shelf of the eastern Adriatic Sea. Although both species are considered critically endangered in the Adriatic and the rest of the world, there are almost no data on the current status of populations, threat assessment and species-specific in-situ conservation. Common angel shark is still present in highly fragmented areas of the eastern Adriatic with extremely rare but consistent records, while smoothback angel shark is mostly considered regionally extinct in the Adriatic due to overfishing and overuse of non-selective fishing gear. There have been only 3 published records of common angel shark this century, the last two of which were reported by fishermen. This paper presents data on 34 new finds, including neonates, juveniles, subadults and adults recorded between January 2020 and August 2021 in the Zadar-Šibenik archipelago (central Adriatic) and one in Premantura (northern Adriatic). Two are original findings during the field expedition, 9 were reported directly by local fishermen, while 23 were reported through a detailed questionnaire. Additionally, plausible breeding and/or nursery grounds between Zadar and Šibenik are discussed with their importance for revitalization and long-term conservation in situ.

The extant graptolite Rhabdopleura recondita has been so far recorded only as inhabiting a bryozoan skeleton. Its larval settlement and metamorphosis are possible in the absence of a bryozoan zoarium, whereas further colony development may require that the larva is hidden inside the bryozoan host. This dependence may constrain the development of R. recondita tube and tubaria compared to the other Rhabdopleura species that develop without a host. We report here on larval settlement and metamorphosis in the absence/presence of a bryozoan host skeleton. We also make the first attempt to test the phenotypical response of R. recondita tubes and tubaria under variable hydrodynamic regimes in laboratory conditions. After 40 days, no significant variation was detected in the number or length of the newly formed tubes. These findings suggest that R. recondita eventually resides in a narrow velocity range and that tube and tubarium development is largely invariable. [ABSTRACT FROM AUTHOR]

Although there is a high number of publications listing fish species in the Adriatic, only a few have focused on chondrichthyans, while their conservation status has been investigated even less. Thus, this paper aims to provide an updated and annotated checklist of the chondrichthyans occurring in the Adriatic waters with their presence and conservation status. Each species is evaluated against the criteria defined in IUCN (International Union for Conservation of Nature) Red List Categories and Criteria and according to the guidelines for national and regional level assessments. In total, 60 chondrichthyan species from 27 families and 42 genera are listed. The list contains 33 species of sharks, 26 species of rays and one chimera. Assessment of the conservation status reveals that three species are now considered Regionally Extinct (namely Squatina oculata, Pristis pectinata and Rhinobatos rhinobatos). A total of 21 species are assessed as Critically Endangered, 8 are Endangered and 10 are Vulnerable. Of the remaining species, six are Near Threatened and the same number of species are Least Concern and Data Deficient. Considering that the principal driver of chondrichthyan decline and regional extinction is overfishing, it is recommended that the Adriatic countries adopt the same management measures and strengthen their coordination.

This project proposal is for the application of IT tools in order to consider a “cross-media” translation of data obtained, so that they can be used as an alternative to simple textual consultation, with respect to the reconstruction of the geography and history of Venetian works of art in the Adriatic regions of the Kingdom of Naples between the Middle Ages and the early modern age. The overall aim of the work is namely to carry out an analysis of Venetian presences and influences in the artistic production of Abruzzo, Molise and Apulia, also considering the transversal relations of this area with the Balkan regions under Venetian rule.

Since the adoption of the Habitats and Birds Directives by EU governments, marine Natura 2000 (N2K) sites have been established in the European Mediterranean Sea, creating one of the largest international networks of protected areas. Nevertheless, to date, marine N2K sites are generally scarcely implemented, studied and monitored, and thus their management effectiveness is weak, and their environmental status is often unknown. The Interreg Italy-Croatia ECOSS project aimed at establishing the ECOlogical observing system of the Adriatic Sea (ECOAdS), to integrate the existing research and monitoring activities in the area, and to promote data sharing at international level, for enhancing monitoring and conservation in Adriatic N2K network. In the framework of ECOSS, a conceptual model was developed and applied to selected N2K sites, to review the existing knowledge, assess site effectiveness, and suggest possible improvements in their monitoring and management based on the contribution that ECOAdS can provide to their implementation. Information on social, ecological, and oceanographic elements related to the conservation and management of these case studies was gathered by consulting the project partners involved in the management and monitoring of the sites and through a literature review. The results of this study revealed a discouraging condition with no management plan in most of the sites, while regulatory measures are generally in place but without surveillance. Monitoring activities are performed occasionally, and information on presence and status of protected species is often lacking or outdated. Although the N2K network provides a unique opportunity to advance marine conservation and achieve the 30% conservation target by 2030, the biggest challenge ahead is the proper management and monitoring of N2K sites. The proposed conceptual model may be taken as a framework to properly set up ecological observing systems in the N2K network and help overcome current limitations, integrating scientific research within the N2K conservation strategies.

The beginning of the Neolithic in the Adriatic region dates back to approximately 6000 cal BC, and the appearance of Impressed Ware pottery marks its generic development. By combining lithic, economic, and paleoenvironmental data, we propose a new arrhythmic model for the chronology of Neolithisation in the Adriatic. On the one hand, the available data suggest that in the south-central part of the basin (Dalmatia and Apulia) the transition to farming was relatively quick, resulting from the colonisation of an open landscape (seemingly linked to the “8.2 ka event” and the onset of a drier climate). These newcomers mostly settled in the fertile plains of the Dalmatian and Apulian hinterlands, basing their subsistence almost exclusively on agriculture and livestock, while lithic blade production in cherts from Gargano (southern Italy) indicates important social aspects and complex management strategies (mining activities, more complex modes of pressure flaking, and specialised distribution networks). However, on the other hand, in the northern Adriatic (Istria, Karst, eastern Po Plain, and Marches), the Neolithic emerged somewhat later, possibly as a result of some form of acculturation. Although available data are still scarce, some evidence suggests that the last Mesolithic groups played an active role in the process of Neolithisation in these areas, where certain Castelnovian traditions have been identified in the lithic production accompanying Impressed Ware (the use of local cherts, lamellar production by indirect percussion, and “simpler” forms of pressure flaking) and in the economy, e.g. importance of fishing.

Tremoctopods are epipelagic argonautoid octopods characterized by their expanded dorsal webs and strong sexual size dimorphism, with dwarfed males. The scarcity of taxonomic features attributed to this genus presents a challenge, and there is growing evidence of species misidentification in Tremoctopus genus on a molecular level. In this study, we investigated four female specimens of blanket octopus Tremoctopus violaceus caught by purse seine fishing in the Central Eastern Adriatic Sea in 2019. Individuals had smooth, firm and muscular bodies, dark bluish purple on the dorsal and iridescent silvery on the ventral side, with dorsal mantle lengths of 113, 82, 80 and 78 mm. The constructed phylogenetic trees based on the 16S ribosomal RNA and cytochrome c oxidase subunit I sequences of investigated Adriatic specimens and publicly available sequences showed strong support for the T. violaceus clade, consisting of individuals collected from the Adriatic Sea, Mediterranean Sea and Atlantic Ocean, with the exclusion of Indo-Pacific clade most probably corresponding to T. gracilis. To fully understand the life-history traits of Tremoctopus species, future research should focus on DNA-based methods for correct species identification combined with morphological characters, geographic distribution and ecological information.

Transitional environments have great ecological value and high productivity, and many species can benefit from their sheltered conditions and food resources. In this study, we performed for the first time a fish-targeted eDNA metabarcoding of the 12S rRNA gene at 16 sites broadly covering the different water bodies of the Marano and Grado Lagoon (northern Adriatic Sea) in two seasons. The eDNA was collected at the same time as the beach seine net, allowing a direct comparison of the two approaches. With eDNA we detected 34 species, covering all the functional guilds occurring in the lagoon. Species of regional interest, that uses the area as a nursery and feeding ground, and diadromous species, highlighting the ecological connectivity between freshwater and marine habitats, were found. While some species were constantly present (e.g. Atherina boyeri, Sparus aurata), others (Squalius cephalus, Platichthys flesus) were influenced by salinity (higher in Grado and lower in Marano), which was confirmed as the main ecological driver in this environment. The comparison with traditional methods, which identified 18 species (11 of which were detected with both approaches), showed that eDNA is very sensitive in detecting most of the biodiversity in the lagoon with a limited sampling effort. Few relevant species (Chelon saliens , Knipowitschia panizzae) lacked reference sequences, which need to be implemented in the databases. Our study represents a significant advance in the understanding of lagoon fish biodiversity and ecological dynamics and contributes to the improvement of management strategies in these ecologically sensitive habitats. • eDNA detected a great richness of fish species, across different functional groups • The molecular approach (eDNA) was more sensitive than the traditional one (seine net) • Reference databases still lack sequences of relevant lagoon fish species [ABSTRACT FROM AUTHOR]

Following the general approach to pilgrimage as established by anthropologists and other scientists, the paper analyses the pilgrimage in Nin to Our Lady of Zečevo. More specifically, this pilgrimage will be observed as a maritime pilgrimage, following relevant recent research. Based on the oral story about the apparition of Virgin Mary to a widow, the statue of Mary is transported from Nin in a boat procession via sea to a mediaeval church on the nearby uninhabited island of Zečevo. Pilgrimage practices include many sensorial and symbolic practices, so it will be analysed from several points of view and more than one theoretical approach, including the relational approach and mobility turn, applied also to maritime pilgrimage with a reflection on influence of tourism on pilgrimage activities, especially in the Mediterranean. The paper relies on the field research from 2020–2023 in Nin near Zadar in Croatia which has been supported in part by the Croatian Science Foundation under the project ‘PILGRIMAR’ (UIP-2019-04-8226).

During the 1840s Italian society began to see the Mediterranean region as a dangerous place to live, owing to what was regarded as threats represented by Austria, Great Britain, France, and even Russia and the United States. This conviction resulted from various affairs both within and outside Europe, where the same powers were accused of behaving in an overtly aggressive way, which was used as an argument for the political unity of Italy's various states in order to give them greater strength for defence. Since danger was seen all around, this unity became important for both the peninsular Italians and the Sicilians, who agreed on the need to establish an Italian league with federal land and naval forces. The principal objective of this paper is to show that the question of Sicily's future was seen as a question of not only Italy's security, but also of its future position in the Mediterranean as a whole, and that the de facto unanimous support of Sicily's membership in the league in 1848 resulted from this self-protecting response that, moreover, already contained proto-imperialist tendencies in which for geostrategic reasons the island played an important role.

Advance in the visualization of the bathymetric and geological data from charted to digital maps and models opened the possibility to analyse data within Geographic Information System (GIS) functionalities. In this paper, bathymetric and geological properties of the Adriatic Sea were analysed using the General Bathymetric Chart of the Ocean (GEBCO) 2020 digital bathymetric model (DBM) and data from the European Marine Observation and Data Network (EMODnet). The bathymetric analysis includes depth statistics, area and volume calculation, hypsometry, and analysis of the heterogeneity of bathymetric data from the GEBCO 2020 DBM within the limits of the Adriatic defined by the International Hydrographic Organization (IHO) and 3 sub-basins delineated according to the bathymetry. The geological analysis includes seabed substrate map from EMODnet data and kilometre-scale seabed variability in the Adriatic. The GEBCO 2020 DBM shows that the Adriatic Sea is a shallow sea with a mean depth of -253 metres and over 50% of area shallower than 100 metres. The area of the Adriatic Sea is 138 516 km2 with a total volume of 35 521 km3. Patterns describing morphological variability coincide with the heterogeneity of the underlying source data of the GEBCO 2020 digital bathymetry model and major structures in the Adriatic Sea.

The article describes a research work aimed at identifying tools to support the activation and environmental regeneration of the open space of the ports in the mid-Adriatic area, an area with untapped potential, though there are significant criticalities. Starting from a set of data taken from the INTERREG Italy-Croatia Joint_SECAP project and, in particular, from the risks and climatic vulnerabilities of the Italian mid-Adriatic city, the contribution presents hypotheses for the light transformation of a part of the port infrastructure through urban micro-forestry interventions. The methodological approach uses simulation tools with a parametric platform that generates proprietary algorithms and allows recursive control over every aspect of the process.

This article examines how four French memorialists recall and represent the former imperial territories of the Illyrian Provinces (1809–1813) on the eastern Adriatic seaboard. It explores how their memoirs deploy Enlightenment ethnography and Romantic exoticism in distinct ways while problematizing these approaches in light of lived experiences in the region. The article thus sheds light on the evolving character of tropes about the western Balkans in early nineteenth-century France, highlighting the influence the landscapes, cultures, and peoples of the territories had on the French officials posted there, including on their later self-presentation as memorialists.

The installation research project Transforming the Adriatic cosmos: insularity, connectivity, and glocal identities of pre-Roman Dalmatia (AdriaCos) (HRZZ UIP-2020-02-2419) began its implementation at the beginning of 2021. This five-year project is financed by the Croatian Science Foundation, and is carried out at the Institute of Archaeology in Zagreb (PI: dr. Marina Ugarković). In the first year of the project there were different interdisciplinary fieldwork, research, and dissemination activities focusing on scientific questions related to the transformations of the island of Hvar and central Adriatic in the 1st millennium BC.

New evidence reveals: 1.) Clustered earthquake patterns at the base of the lithosphere/upper mantle concentrated mostly within the ocean basins. 2.) Followed by Sea Surface Temperature (SST) anomalies hypothesized to originate from underlying magma generation and seafloor heat release during hydrothermal venting. Joule heating at the base of the lithosphere created from electrical emanations deep within the core-mantle-boundary manifest as clustered earthquakes could provide the driving mechanism for elevated temperatures. Clustered earthquake swarms at 10km depths, which burst pulse over short, several days- to week-periods appear correlated to subsequent Sea Surface Temperature (SST) anomalies and a reversal in Adriatic Sea circulation. Authors suggest this and other like events may be the natural drivers of global warming.

Pinna nobilis is a large bivalve endemic to the Mediterranean Sea that lives in shallow coastal areas. Due to its size and relatively fast shell growth rates, it is an interesting taxon for high-resolution study of nitrogen isotopes of carbonate bound organic matter (δ15NCBOM). In this study we tested if P. nobilis shells can be used as an indicator of the nitrogen isotope baseline of the system, if it can provide high-resolution data on environmental δ15N variability, and if the chemical properties of the shell and biomineralization process change in response to mass mortality events spreading in the Mediterranean. Shells were opportunistically collected during 2019 and 2020 by skin diving, as a part of a project on mortality monitoring, from four shallow coastal localities in the eastern Adriatic. Shell powder for δ15NCBOM analysis was collected by milling sample swaths from the internal (low-resolution) and external (high resolution) shell surface. Significant differences in δ15NCBOM, obtained from the internal shell surface, were observed between sampling localities with different anthropogenic influences, with lowest values (∼3–4‰) recorded for shells obtained from Pag Bay, and highest (∼6–8‰) for shells sampled in Lim and Kaštela Bays. High-resolution samples from the external shell surface of Pinna nobilis showed spatial and temporal variations in δ15NCBOM values, with temporal resolution of 1–3 weeks. High-resolution δ15NCBOM data obtained from the shell Kas1 corresponded to a time interval from spring 2018 to summer 2019 and had a pronounced increase of δ15NCBOM values closest to the shell margin coupled with a decrease in δ13Cshell values, indicating that this animal was experiencing stressful conditions several months prior to its death. According to our findings, δ15NCBOM values from P. nobilis shells can serve as an indicator of the isotopic baseline of the ecosystem potentially as a powerful tool to study bivalve physiology.

Croatia’s coast located on the eastern Adriatic is rich with small gravel beaches with limited fetch. This leads to a specific low-energetic wave climate compared to most other beaches, while their gravel composition makes them unique. Most management of these beaches is performed without understanding the sediment transport occurring on the beaches. XBeach-Gravel is a numerical model capable of simulating bed-level change on gravel beaches, but lacks validation in the case of low significant wave height (under 2.5 m) and low peak periods (under 6 s), conditions that are present on the eastern Adriatic. Based on measurements performed in both laboratory conditions in a water canal in Hannover and actual storm wave conditions on Ploče beach, calibration of the model is performed. Model results are compared between laboratory conditions and field conditions for comparable wave conditions. XBeach-Gravel can simulate low-energetic events resulting in berm formation and berm buildup with a high Brier skill score if calibrated. Simulation of laboratory conditions requires high transport coefficient values and shows more sediment transport than similar wave conditions in the field. Calibration for field conditions is dependent on geodetic survey data capable of isolating wave events with dominant cross-shore transport, but once calibrated, XBeach-Gravel can achieve good to excellent Brier skill score values in simulating sediment change in low-energetic wave conditions on the eastern Adriatic.

One shark was landed at the Naval Base Pasha Liman, Bay of Vlore, Albania, the Adriatic Sea. Photographic records only enabled the specimen to be placed in family Odontaspididae or Carchariidae. Later examination of the preserved head, dry jaw and dentition identified the specimen as Odontaspis ferox. This is a rare record and the northernmost Mediterranean observation of this species, and the first Adriatic record for several decades. [ABSTRACT FROM AUTHOR]

The extant graptolite Rhabdopleura recondita has been so far recorded only as inhabiting a bryozoan skeleton. Its larval settlement and metamorphosis are possible in the absence of a bryozoan zoarium, whereas further colony development may require that the larva is hidden inside the bryozoan host. This dependence may constrain the development of R. recondita tube and tubaria compared to the other Rhabdopleura species that develop without a host. We report here on larval settlement and metamorphosis in the absence/presence of a bryozoan host skeleton. We also make the first attempt to test the phenotypical response of R. recondita tubes and tubaria under variable hydrodynamic regimes in laboratory conditions. After 40 days, no significant variation was detected in the number or length of the newly formed tubes. These findings suggest that R. recondita eventually resides in a narrow velocity range and that tube and tubarium development is largely invariable.
