Abstract
Razgradnja listinca bukve (Fagus sp.) i lopuha (Petasites spp.) praćena je 2007. godine u akvatoriju NP Plitvička jezera. Metodom “paketića listinca” dobiveni su podaci o brzini raspadanja listinca tijekom jednogodišnjeg razdoblja te za dvije kraće eksperimentalne serije. Listinac lopuha, kao zeljaste biljke, se razgrađivao znatno brže od listinca bukve, koja kao drvenasta biljka ima veći udio lignina te je zbog toga process razgradnje sporiji. Na listincu lopuha i bukve se nitrati apsorbiraju tokom hladnijih mjeseci, a ispiru tijekom toplijih mjeseci. Generalno listinac bukve ima manji sadržaj nitrata. Koncentracija fosfata raste na listincu lopuha s vremenom ekspozicije, dok se s listinca bukve fosfati uglavnom ispiru. Razlog za takve trendove apsorpcije nitrata i fosfata je razlika u mikrobnoj aktivnosti na listincu tijekom godine, pri čemu temperatura vode ima ključan utjecaj.
Abstract (english)
Leaf litter decomposition of two species; common beech (Fagus sp.) and butterbur (Petasites spp.) was investigated during 2007 in lakes of Plitvička jezera national park. Data on decomposition rate were gathered for the whole year exposition as well as for two short experimental series using the methods of “leaf packs”. Leaf litter of butterbur, as herbaceous plant, showed faster decomposition compared to leaf litter of common beech, which, as woody species, have higher proportion of lignin making the process of decomposition slower. On both species nitrates were absorbed during cold seasons, while process of leaching dominated during warm seasons. Generally, the beech leaf litter had lower content of nitrates. Concentration of phosphates mainly increases with exposition time on butterbur leaf litter, while they were mainly leached from beech leaf litter. Difference in the activity of microorganisms during the year, mainly influenced by water temperature is a possible reason for observed trends.
