The present knowledge of the carbonate system in the northern Adriatic is described in this short overview. Its buffer capacity is rather high, due to riverine input of carbonates dissolved from ...Alpine and Karstic watersheds, and the waters should have a higher resilience to acidification. In the shallow eutrophic areas, the combined effect of rising atmospheric CO2, warming and river-induced anthropogenic CO2 with the associated decrease in buffer capacity could act to acidification process. Significant effect on calcifying organisms is expected in the future.
Predstavljena je vsebina knjige v tisku pri založbi AGU-Wiley z naslovom »Obalni ekosistemi na prehodu: Primerjalna analiza severnega Jadrana in Zaliva Chesapeake« urednikov T. Maloneja, A. Malej in ...J. Faganelija. Knjiga prinaša primerjavo ekosistemov severnega Jadrana in Zaliva Chesapeake (vzhodna obala ZDA) in širi znanje o antropogenih vplivih na obalne ekosisteme, kjer je koncentrirano tako prebivalstvo kot izkoriščanje naravnih virov. Ponovni pregled obeh ekosistemov je omogočil, da smo ocenili spremembe v zadnjih 20 letih, še posebej lokalne vplive v okviru globalnih podnebnih sprememb ter uspešnost posegov za upravljanje in zmanjšanje antropogenih vplivov na obalne ekosisteme.
Kvarner v času železne dobe severnega Jadrana V starejši železni dobi severnega Jadrana je poleg Istre imel posebno mesto tudi Kvarner. Njegovo vlogo in pomen v komunikacijah in kroženju blaga v ...tistem času nakazujejo starejše in novejše raziskave. čeprav so se v zadnjih dveh desetletjih izvajale predvsem zaščitne arheološke raziskave, je bilo poleg posameznih najdb zbrano veliko novega gradiva, nekaj tudi povsem nepričakovanega. V članku je predstavljen kratek pregled raziskovalcev in stanja raziskav, opisane so reprezentativne ostaline materialne kulture ter pomembnejše najno- vejše najdbe, ki omogočajo obravnavo kvarnerske skupnosti v novi luči, zlasti v konkretnejši povezavi s sosednjimi, a tudi oddaljenimi kulturnimi skupnostmi od Alp do Jadrana in od Apeninov do Balkana.
The research aim was to assess the dynamics of the North Adriatic pastoral landscape (Ćićarija, Croatia) with regard to the coenological composition of grassland communities, and, more specifically, ...to: i) assess the current grassland mosaic from a coenological viewpoint; ii) assess the effects of management abandonment on grassland species composition, also taking into account, as a basis for comparison, data on pastoral communities collected in the past decades. To achieve the research aims, 73 phytosociological relevés were carried out; for each of them field data (altitude, aspect, slope, landform) and information on grassland management were collected. Multivariate analysis of phytosociological relevés led to the identification of four vegetation types (Danthonio-Scorzoneretum villosae, Carici humilis-Centaureetum rupestris, Brachypodium rupestre-dominated stands, and Anthoxantho-Brometum erecti), which were linked to landform and to grassland management. Comparison in terms of social behaviour type composition of the grassland communities surveyed in the present study with the ones surveyed in the past decades, highlighted that the current management (grassland abandonment, as well as low intensity grazing and not periodic mowing) is leading to a percentage loss of pasture and meadow characteristic species, in favour of successional and ruderal ones.
Namen raziskave je bil ovrednotiti dinamiko severnojadranske pašniške krajine (Čićarija, Hrvaška) predvsem cenološke sestavo travniških združb. Posebej smo želeli ugotoviti: i) trenuten travniški mozaik s cenološkega vidika, ii) spremembe opuščanja gospodarjenja na vrstno sestavo travnikov s primerjavo podatkov o pašnikih, pridobljenih v preteklih desetletjih. Naredili smo 73 fitocenoloških popisov in za vsakega od njih smo pridobili podatke o višini, legi, nagibu, krajinski obliki in informacijo o gospodarjenju. Z multivariatnimi analizami smo ugotovili štiri vegetacijske tipe (Danthonio-Scorzoneretum villosae, Carici humilis-Centaureetum rupestris, združbo z dominantno vrsto Brachypodium rupestre in Anthoxantho-Brometum erecti), ki smo jih povezali s krajinsko obliko in načinom gospodarjenja. Primerjava sestave zgradbe travniških združb glede na sinsociološko pripadnost vrst med današnjimi in starejšimi popisi je pokazala, da trenuten način gospodarjenja (opuščanje gospodarjenja, nizka intenziteta paše in le občasna košnja) vodi v izgubo značilnih vrst pašnikov in travnikov na račun vrst razvitejših sukcesijskih stadijev in vrst ruderalnih rastišč.
The results of the international collaboration of the three institutions from Austria, Italy and Slovenia (Alpen-Adria-Universität Klagenfurt, Università degli studi di Udine and ...Znanstvenoraziskovalni center SAZU, Inštitut za arheologijo of Ljubljana) are being published in the Studia Alpium et Adriae series.New discoveries and the re-examination of old ones is offering new insights into the Roman army and the historical questions related to its presence and activity in the regions of the northern Adriatic and the eastern Alps. The first volume of Studia Alpium et Adriae contains the contributions of twenty-one authors from four countries (Italy, Slovenia, Croatia and Austria) who present the results of their work conducted in recent years within different research groups and projects.
