Abstract
U jezeru Sakadaš (PP Kopački rit) i rijeci Dravi praćena je dinamika razvoja zajednica zooplanktona uzorkovanih u neposrednoj blizini mikroplastike. Obraštaj koji se razvija na mikroplastici (plastisfera) predstavlja značajan izvor hrane za više trofičke nivoe te može utjecati na dinamiku razvoja okolnih zajednica. Istraživanje je provedeno tijekom 2019. godine u vremenskom razdoblju od pet tjedana s ciljem utvrđivanja kvalitativnog i kvantitativnog sastav zajednice zooplanktona te potencijalnih razlika između zajednica u jezeru Sakadaš i rijeci Dravi izloženih istom tipu, veličini i količini mikroplastike. U jezeru je zabilježena veća brojnost, biomasa i broj funkcionalnih skupina u usporedbi s rijekom. Dok su u jezeru Sakadaš ko-dominirali bakterivori, mali algovori i jedinke koje se hrane većim algama (do 50 μm) u rijeci su dominirali bakterivori s malim udjelom jedinki koje se hrane algama malih dimenzija (do nekoliko μm). Klaster analizom brojnosti jedinki funkcionalnih skupina ustanovljeno je da su četvrto i peto uzrokovanje vode iz rijeke Drave sličniji uzorcima jezera Sakadaš nego ranije uzorkovanim zajednicama istog lokaliteta. Na temelju rezultata moguće je zaključiti da plastisfera u riječnom ekosustavu ima značajniji utjecaj na dinamiku razvoja planktonskih zajednica negoli u jezeru te su daljnja istraživanja prijeko potrebna u svhu uspješnog razumjevanja tematike i primjerene zaštite vodenih ekosustava.
Abstract (english)
In lake Sakadaš (Nature Park Kopački rit) and in Drava River zooplankton community development near microplastics was monitored. Periphyton that develops on microplastics (plastisphere) represents a significant food source for higher trophic levels and can affect the development of surrounding communities. The research was conducted in 2019 over five weeks to determine qualitative and quantitative zooplankton community composition and the potential distinction between communities in lake Sakadaš and Drava River exposed to the same type, size and amount of microplastics. In lake, a higher abundance, biomass and number of functional groups were recorded compared to the river samples. Bacterivores, small algivorous and individuals that feed on larger algae (50 μm) co-dominated in lake Sakadaš, while bacterivores with a small contribution of individuals that feed on small dimension algae dominated in the river. Cluster analysis based on functional groups showed that the fourth and fifth water sampling from Drava River was more similar to the lake samples than to previously sampled communities of the same site. It is possible to conclude that plastisphere has a more significant impact on plankton development in rivers than in lakes and further research is needed for better understanding of the topic and adequate protection of aquatic ecosystems.
