Abstract
Istraživani su sedimenti u slanoj močvari na ušću rijeke Mirne u Istri. Terenska istraživanja sastojala su se od plitkog jezgrovanja sedimenta na profilu od kopna prema moru. Na odabranim intervalima sedimentnih jezgara provedena je granulometrijska i mikropaleontološka analiza. U tu svrhu svaki odabrani uzorak je podijeljen za analizu mokrim sijanjem i sedigrafom, te za mikropaleontološko standardiziranje uzoraka za određivanje rodova i vrsta foraminifera i druge prateće biote. Rezultati granulometrijske analize potvrdili su sitnozrnati karakter i vrlo lošu sortiranost sedimenta u svih sedam jezgri, mikropaleontološkom obradom pronađeno je 8 foraminiferskih vrsta i 14 rodova. Za slanu močvaru sitnozrnati muljeviti sedimenti i mala raznolikost zajednice tipične su karakteristike s obzirom na nestabilnost takvog okoliša. Najbrojnija vrsta je Ammonia tepida, a veliku zastupljenost ima Trochammina inflata, vrste koje su rasprostranjene obalnim močvarama širom svijeta. Vrijednosti indeksa bioraznolikosti slijede manje promjene u osobinama okoliša kako prostorno tako i kroz vrijeme.
Abstract (english)
Seven shallow cores were collected in a salt marsh at the mouth of Mirna River in Istria along the land-to-sea transect. Granulometric and micropaleontological analysis were performed at selected intervals of each sediment core. The cores were sliced into 2 cm thick intervals, and selected samples were subjected to wet sieving and sedigraph analysis, whereas for micropaleontological studies, determination of foraminiferal genera and species and other accompanying biota were done on standardized aliquots. The results of the granulometric analysis confirmed the fine-grained character and the very poor sediment sorting in all 7 cores. Altogether, 8 foraminiferal species and 14 genera have been identified. The salt marsh is characterized by muddy sediments and low biodiversity (due to unstable conditions). The most common species is Ammonia tepida, followed by Trochammina inflata, both species are universally present in marshes all over the world. Values of biodiversity indices show some changes in characteristics of environment, both spatial and temporal.
