Abstract

Cretovi su jedinstveni močvarni ekosustavi u kojima vladaju posebni životni uvjeti kojima su se prilagodili specifični vodeni i kopneni organizmi. Zbog klimatskih promjena, prirodne sukcesije, eksploatacije i degradacije, spadaju u kritično ugrožena staništa i zbog toga je poduzimanje mjera očuvanja cretova veoma bitno. Praživotinje se često koriste u istraživanjima kao bioindikatori za praćenje promjena u cretnim ekosustavima. Cilj ovog istraživanja bio je utvrditi mogu li se trepetljikaši koristiti kao rani bioindikatori učinkovitosti restauracijskih mjera na cretu Đon močvar, najvećem hrvatskom cretu, koji je u opasnosti od zaraštavanja. Nakon uklanjanja drvenaste i travnate vegetacije na cretu provedeno je uzorkovanje na 3 tipa staništa: revitaliziranim, sukcesijskim i kontrolnim postajama, na 4 plohe, od travnja do studenog 2015. Ukupno je zabilježeno 45 svojti trepetljikaša od kojih su najbrojnije svojte bile Platyophrya sphagni i porodica Oxytrichidae. Na raznolikost i brojnost trepetljikaša utjecala je vlažnost, temperatura, količina otopljenog kisika i provedene revitalizacijske mjere. Dobiveni rezultati ukazuju na brz oporavak creta nakon provedenih mjera revitalizacije, te potvrđuju da se trepetljikaši mogu koristiti kao bioindikatori revitalizacije creta.

Abstract (english)

Peat bogs are unique wetland ecosystems with specific living conditions, harbouring various adapted aquatic and terrestrial biota. Due to climate changes, progressive succession, exploitation i degradation, they are highly endangered habitats worldwide, making preservation measures very important. Protozoans are often used in research as bioindicators to monitor changes in peat ecosystems. The aim of this research was to investigate whether ciliates can be used as an early bioindicator of the effectiveness of restoration measures on the Đon močvar peat bog, the largest peat bog in Croatia, which is in danger of overgrowing. After the removal of woody and grassy vegetation, samples were collected on 3 types of habitats, revitalized, successive and control, on 4 plots, from April to November 2015. A total of 45 ciliate taxa were recorded, with dominant taxa Platyophrya sphagni and family Oxytrichidae. Humidity, temperature, dissolved oxygen and revitalization measured influenced the number and abundance of taxa. The results showed rapid recovery of peat after revitalization measures, and confirm that ciliates can be used as bioindicators in peat habitats
