Abstract

Ovaj rad istražuje raznolikost praživotinja i mikro-beskralješnjaka u šumskom tlu u odabranom nižem šumskom pojasu Parka prirode Medvednica. Glavni ciljevi istraživanja bili su analizirati sastav i strukturu njihovih zajednica u tlu te usporediti njihovu raznolikost u ovisnosti o vrsti drveća. Uzorci tla prikupljeni su ispod tri vrste drveća: običnog graba, hrasta kitnjaka i običnog bora te potom analizirani metodom „nepoplavljenih Petrijevih zdjelica“. U tlu je pronađeno 49 svojti, od kojih su trepetljikaši bili najzastupljeniji od praživotinja, a potom okućeni. Od mikro-beskralješnjaka najzastupljeniji su bili oblići u većini uzoraka. Rezultati su pokazali da vrsta drveća utječe na sastav i strukturu zajednica, pri čemu je najveći broj svojti zabilježen u tlu ispod običnog graba, a najmanji ispod običnog bora. Opažena veća raznolikost zajednice u tlu ispod običnog graba ukazuje na to da biljna vrsta stvara specifično okruženje i uvjete u tlu koji se mogu odraziti na zajednice praživotinja i mikro-beskralješnjaka koji u njemu obitavaju.

Abstract (english)

This study investigates the diversity of protozoa and micro-invertebrates in the forest soil within a selected lower forest zone of the Medvednica Nature Park. The main objectives of the research were to analyze the composition and structure of these organisms' communities in the soil and to compare their diversity in relation to the tree species. Soil samples were collected beneath three tree species: common hornbeam, sessile oak, and Scots pine, and analyzed using the "non-flooded Petri dish" method. A total of 49 taxa were found in the soil, with ciliates being the most prevalent among protozoans, followed by testaceans. Among micro-invertebrates, nematodes were the most common in most samples. The results showed that tree species influence community composition and structure, with the highest number of species recorded in the soil under the common hornbeam and the lowest under the Scots pine. The observed higher diversity in the soil under the common hornbeam suggest that the plant species creates a specific environment and conditions in the soil that can affect the communities of protozoa and micro-invertebrates.
