Abstract
Slana močvara Lokunja poznata je po zdravom blatu. Ručnim uzorkovanjem prikupljena su četri uzorka sedimenta. Mokrim sijanjem su izdvojene foraminifere i ostrakodi čije su vrste taksonomski određene. Mikropalaeontološke analize provedene su na uzorcima ispranim na situ promjera rupica 63 μm, a ostatak je iskorišten za granulometrijsku analizu. Bioraznolikost foraminiferske zajednice određena je na temelju pet ekoloških indeksa. Populacijska dinamika je napravljena na dominantnoj foraminiferskoj vrsti Ammonia parkinsoniana (d'Orbigny). Bogatstvo vrsta u svim ispitivanim uzorcima varira (vrijednosti su od 4 do 8), dominacija pokazuje maksimalnu vrijednost 0,43. Vrijednosti indeksa ukazuju na lagunski, hiposalinski okoliš. Zajednicu A. parkinsoniana karakterizira gausova (normalna) raspodjela veličine, a najbrojnije su jedinke u rasponu 260-300 μm. Uzorci sadrže brojne karapakse vrste ostrakoda Cyprideis torosa (Jones), široko rasprostranjene eurhalinske forme. Mala raznolikost zajednica mikro-organizama, dominacija adultnih jedinke bentičke foraminifere, ujednačena veličina ljuštura ostrakoda kao i prisustvo isključivo muških jedinki, sve to sugerira post-mortem nakupljenih ostataka.
Abstract (english)
Saltmarsh Lokunja is well known for its healthy mud. Four samples were collected by hand sampling. Wet sieving method was applied, and foraminifera and ostracods were taxonomically identified on species level. Micropalaeontological analyses were performed on samples washed through a 63 μm sieve, and the rest of the samples were used for granulometric analysis. The biodiversity of the foraminiferal community was determined on the basis of five ecological indices. Population dynamics were made on the dominant foraminiferal species, on Ammonia parkinsoniana (d'Orbigny). Index of Species richness, in all samples, varied from 4 to 8, dominance showing a maximum value of 0.43. The values of all indices suggest hyposaline, lagoonal setting. The population of A. parkinsoniana is characterized by a Gaussian (normal) size distribution pattern, with peaks occurring among specimens of 260-300 μm diameters. All ostracod assemblages are dominated by Cyprideis torosa (Jones), a widespread euryhaline species that can live from freshwater to hypersaline conditions. Low values of ecological indices, the dominance of adult foraminiferal specimens, carapaces of the same sizes of male individuals, all these suggest post-mortem transport of remains of organisms.
