Tijekom prve polovice 2021. godine započeta je ponovna procjena arheološkog potencijala otoka Biševa. Dugoročni cilj je sprječavanje devastacije kulturnog krajolika otoka te njegovo uključivanje u turističku ponudu područja. Nedestruktivnom metodom arheološkog terenskog pregleda zabilježeni su potencijalni položaji lokaliteta koji će služiti za izradu topografske karte. Uz dosad poznate lokacije, otkriveni su i novi mogući položaji s vidljivim pokretnim i nepokretnim arheološkim nalazima. Dosad provedena istraživanja služit će kao temelj za daljnje intenzivne arheološke preglede i sondažna istraživanja

Obiettivo del presente contributo è illustrare il valore di alcuni documenti afferenti all'archivio del monastero benedettino delle isole Tremiti in riferimento alla struttura politica e sociale di città ed insediamenti della costa dalmata ed ai rapporti tra le due sponde dell'Adriatico nel corso dell’XI secolo. Per tentare di raggiungere il primo scopo, l'articolo si concentra in prima istanza sull'analisi di due documenti: il primo, risalente al 1023, riguarda la fondazione del cenobio di S. Benedetto sull'isola di Lacroma (Lokrum), affidato, per volontà degli abitanti di Ragusa (Dubrovnik) e del suo arcivescovo, alla guida di un religioso di origine ragusea formatosi presso la comunità tremitese; il secondo invece rammenta la sosta presso l'abbazia pugliese che alcuni viaggiatori che si definiscono Mariani, forse provenienti dai territori balcanici prospicienti l'arcipelago, compirono nell'estate del 1050, quando essi decisero di affidare alla congregazione isolana la chiesa-monastero di S. Silvestro, sull'isola di Busi (Biševo), nei pressi di Spalato. Partendo dal contenuto di questi atti si sono tentate delle considerazioni sulla struttura politica e sociale del panorama dalmata, sia per quanto riguarda le città ancora legate alla tradizione romana, quale Ragusa, sia per quelle aree oramai definitivamente assorbite nel mondo culturale slavo. La seconda parte del contributo invece, è dedicata all'esame di alcuni documenti riguardanti due villaggi collocati sul promontorio del Gargano (Puglia), Devia e Peschici, dove, nella prima metà dell'XI secolo, vivevano popolazioni di chiara etnia slava. La citazione dello župan, una carica civile tipica del mondo slavo, induce a credere che tali comunità avessero preservato le strutture organizzative delle terre da cui provenivano fino alla conquista normanna, nel 1054. L'articolo si conclude con alcune riflessioni sul ruolo di intermediario culturale nonché di polo religioso ricoperto dal monastero delle Tremiti all'interno del bacino adriatico durante il medioevo e non solo e sulla possibilità di motivare la nascita di un luogo sacro sul piccolo arcipelago con la sua funzione di facile tappa lungo la navigazione. The aim of this paper is to explain the importance of some documents in the archive of the Benedictine abbey on the Tremiti Islands relative to the political and social organisation of some Dalmatian coastal cities and settlements and about the relationships between the Croatian and the Italian shores in the 11th century. To achieve the first aim, the paper dwells upon the analysis of two documents: the first, dated 1023, concerns the foundation of the Benedictine coenobium on the island of Lokrum, entrusted by the inhabitants of Ragusa (Dubrovnik) and its Archbishop to a monk of Ragusan origin, and a member of the Tremiti monastic community. The second document refers to a stop in the Tremiti Abbey made in the summer 1050 by some travellers, called Mariani, probably coming from the opposite coast, who donated to the monastic congregation of the Island the Church and the monastery of St. Sylvester on the Biševo island, near Split. Through the analysis of these documents, the paper attempts to make some considerations about political and social settings of Dalmatia, both about a city like Ragusa, still close to the Roman legacy, and the lands completely involved in the Slavic cultural environment. The second part of the paper is dedicated to the study of some documents concerning two villages - Devia and Peschici, on the Gargano promontory in Apulia, where some Slavic populations lived in the first half of the 11th century. Reference to župan, a public office typical of the Slavic heritage, proves that these communities had preserved the organisation of their homeland until the Norman conquest in 1054. The paper ends with considerations about the role of the cultural mediator and religious centre in the Adriatic area played by the Tremiti Abbey during the Middle Ages and later periods, and about the possibility to explain the foundation of a sacred place on this small archipelago with its function of an easy stop during the navigation.

Na temelju bioloških markera načinjena je nova rekonstrukcija kolebanja morske razine tijekom posljednjih 1500 godina na području Srednjeg Jadrana. Na otocima Visu, Biševu i Ravniku pronađene su i analizirane mediolitoralne biokonstrukcije koje grade koralinske alge, naročito vrsta Lithophyllum byssoides, koje se smatraju iznimno preciznim markerima (± 10 cm) morske razine (Laborel i dr., 1994). Izabrane su 3 lokacije, na svakom otoku po jedna, gdje su algni vijenci najbolje razvijeni širine i do 1, 8 m, dok maksimalne vrijednosti zabilježene u Mediteranu dosežu 2 m. Postojanje tako velikih i dobro razvijenih algnih vijenaca općenito upućuje na izdizanje morske razine. Algne biokonstrukcije su kartirane i datirane pomoću metode 14C. Rezultati upućuju na četiri faze kolebanja morske razine. Od oko 550 do oko 770 cal AD morska razina je bila relativno stabilna za vrijeme hladnog ranog srednjevjekovnog perioda. Potom, za vrijeme toplog Srednjeg vijeka (770 do 1330 cal AD), morska razina se počinje izdizati brzinom od 0, 71 mm/god. Za vrijeme Malog ledenog doba (1330 do 1640 cal AD) morska je razina ponovo relativno stabilna. Potom morska razina ponovo znatno brže raste, osobito tijekom aktualnog toplog razdoblja (Faivre i dr., 2013). Dobiveni rezultati su uspoređeni s lokalnim procjenama glacio-hidro-izostatičkih modela temeljenih na posljednjem Glacijalnom ciklusu (Lambeck i dr. 2004 ; Lambeck i Purcell, 2005). Rezultati istraživanja pokazuju da su se veliki algni vijenci najbolje razvijali u fazama kada je morska razina bila stabila tj. kroz dva hladnijia perioda, te da su najveći vijenci širine do 1, 8 m nastali tijekom 300 godina stabilizacije morske razine na Srednjem Jadranu.

Otok Biševo je smješten 9 km JZ od otoka Visa i geografski pripada srednjodalmatinskim otocima, odnosno geotektonskoj jedinici Vanjskih Dinarida. Biševo strukturno predstavlja sinklinalu s foraminiferskim vapnencima oligocenske starosti u jezgri (na geološkoj karti list Vis, 1:100000, Borović i sur., 1968, naslage su opisane kao eocenske), te s krilima izgrađenim od naslaga kredne starosti. Naslage uvale Mezoporat na otočnoj istočnoj obali pripadaju ranom oligocenu (rupelu) na što upućuju nalazi vrste Nephrolepidina praemarginata Douvillei. Okoliš u kojem su naslage taložene prepoznat je kao okoliš visoke energije gdje se vršilo pretaloživanje sedimenta iz plitkomorskih laguna, otvorenih zaljeva i rubova platformi valovima, odnosno facijes prerađenih vapnenaca.

Ovaj list prikazuje geološku građu, odnosno prostorni raspored, stratigrafske i tektonske odnose te temeljnu paleontologiju i petrologiju 21 litostratigrafske jedinice različite geološke starosti (trijas, kreda, paleogen, neogen i kvartar) na području šireg viškog arhipelaga. Ovo je prvi list OGK RH koji je izrađen prema pisanom geološkom standardu (Upute za izradu Osnovne geološke karte Republike Hrvatske mjerila 1:50 000), u okviru projekta od strateškog nacionalnog interesa, koji pokriva jednu geološko-geografsku cjelinu.

On the particularly exposed sites on rocky coasts of the Central Adriatic islands (Vis, Ravnik and Biševo) in Croatia, biogenic littoral rims built by the coralline rhodophyte Lithophyllum byssoides (formerly known as L. lichenoides) were found. They were mapped, measured and sampled for 14C dating. The presence of thick and well-developed Lithophyllum rims, considered to be precise (±10 cm) sea-level indicator (Laborel, 1986 ; Laborel et al., 1994), points directly to the rising sea-level environment. Here we present new sea-level reconstruction for the past 1.5 ka years based on this biological indicator. The obtained results revealed four phases of sea-level changes. The sea-level was near stable from around 1400 till 1170 cal BP, in the Dark Ages Cold Period (DACP), then during the Medieval Climate Anomaly (MCA) 1170 till 620 cal BP the sea-level increased at a rate of 0.71 mm/yr. During the Little Ice Age (LIA) 620 till 310 cal BP it was near stable again. Later, the sea-level started to rise at a much speedier rate particularly during the Current Warm Period (CWP). These data were compared with predictions derived from a glacio-hydro-isostatic model associated with the Last Glacial cycle (Lambeck et al., 2004 ; Lambeck and Purcel, 2005). If the isostatic-eustatic component is separated, this area reveals almost stable tectonic conditions during the past 1500 years. Our results show that large algal rims grew during near-stable sea-level conditions that occurred during two relatively colder periods in the past 1500 years. They also reveal that well-developed (up to 1.8 m wide) upper levels of algal rims were formed during the 300 years of stabilisation during the LIA, which also corresponds to the time needed for the formation of the tidal notch that is widespread and slightly submerged today. The obtained results have been also compared with archaeological markers, e. g. submerged port remains of the ancient Issa harbour on the island of Vis (Faivre et al., 2010) and other available data along the Croatian coast.

On the particularly exposed sites on rocky coasts of islands Vis, Ravnik and Biševo in Croatia, biogenic littoral rims built by the coralline rhodophyte Lithophyllum lichenoides can be found. The presence of thick and well- developed Lithophyllum rims, considered to be precise (±10 cm) sea-level indicator, points directly to the rising sea-level environment. Up to now five locations have been studied: 3 on the island of Vis, 1 on Ravnik and 1 on the island of Biševo. Biogenic rims were mapped, measured and sampled for 14C dating. Three of the researched algal structures have two dominant levels: the upper one, 6 m long and 40 to 150 cm wide, and the lower one with a maximal extension of 40 cm. The surface of the lower level is 60 cm below the recent one. The thickness of each level at its most protruding part is around 15 cm. Today, on the relatively horizontal surface of the upper level algal rims the process of biodestruction prevails over bioconstruction. Living talli of Lithophyllum lichenoides were found only in small patches at the highest position on the horizontal surface of the rim and along its upper limit. Such a situation could clearly be connected to the recent acceleration of the sea-level rise as mentioned by Laborel et al., 1994. The prograding morphology of the algal rims points to the slowing of the sea-level rise starting at around -1m below the MSL, when the algal rims began to develop. Based on the archaeological markers from 2300±100 yr BP till around 1900 ±100 yr BP the rate of relative sea level change was around 0.89 mm/yr (Faivre et al., in press) and then, according to the 14C dated algal samples it slowed down to 0.45 mm/yr from around 1450 yr BP till today. The obtained results have been compared not only with archaeological markers, e. g. submerged port remains of the ancient Issa harbour on the island of Vis, but also with geomorphological sea-level markers, as well as with other available data along the Croatian coast.

U radu su obrađena osnovna geografska obilježja pučinskog otoka Biševa.

Floristic research on the island of Biševo was carried out during the spring of 2000 and 2001. A total of 32 taxa of vascular plants were recorded for the first time. Among them, 23 taxa are autochthonous and 9 are cultivated or formerly cultivated. The island is new locality for orchids Ophrys tommasinii Vis. and Ophrys x lyrata H. Fleischm. This paper also confirms the existence of the neglected species Reichardia intermedia (Sch.Bip.) Cout. and until now doubtful species Euphorbia terracina L. in the Croatian flora. On the basis of our research and the floristic data published so far, flora of the island of Biševo now consists of 421 plant taxa, which were recorded before the fire that occurred in August of 2003, when 80% of the island was devastated.

In spite of several breaks in the sedimentary sequence in Biševo (Adriatic Sea) marked by conglomeratic beds, the sequence is dated as Lower Oligocene based on larger foraminifera assemblage.

Članak govori o brodolomu, spašavanju i obnovi posljednje komiške tradicionalne ribarske barke - gajete falkuše. Riječ je o jedinstvenom hrvatskom i mediteranskom tipu ribarskog broda koji ima duboke korijene u povijesti, a unatoč tome nije prepoznat na razini nacionalne kulture kao kulturno dobro. Članak govori o događaju spašavanja jedne barke koji je ujedno i povijesni događaj jer je označio spas posljednjeg primjerka unikatnog mediteranskog broda i početak projekta njegove rekonstrukcije i svjetske promocije.
