Abstract

Poznato je da se putem analize makrozoobentosa može dobiti uvid u ekološko stanje voda. U ovom radu se napravila identifikacija i usporedba organizama koji nastanjuju Halasz Csardu i određeno područje rijeke Drave, dok je pristup jezeru Šoderica bio onemogućen, čime se dobio uvid u stupanj zagađenja tih područja. Ljudska aktivnost na pojedinim lokacijama može značajno utjecati na kvalitetu i sastav vode. Tijekom svibnja, lipnja i srpnja uzimali su se uzorci makrozoobentosa sa obje lokacije te su identificirani do najniže moguće taksonomske kategorije. Izračunom Shannon-Wienerovog i Simpsonovog indeksa došlo se do zaključka da je na obje lokacije diverzitet vrsta nizak, i da je sastav vrsta na lokacijama sličan. Putem sakupljenih indikatorskih vrsta, tj. putem proučavanja otpornosti tih organizama na stupanj onečišćenja vode, došlo se i do zaključka da je njena kvaliteta na obje lokacije barem srednjeg stupnja onečišćenja, iako je na rijeci Dravi njena kvaliteta malo viša.

Abstract (english)

It’s known that the analysis of macrozoobenthos can provide insight into the ecological status of bodies of water. This paper will identify and compare the organisms that inhabit Halasz Csarda and a specific area of the Drava River, while lake Šoderica was inaccessible, providing insight into the degree of pollution in those areas. Human activity in certain locations can significantly affect the quality and composition of water. During May, June, and July, samples of macrozoobenthos were taken from both locations and identified to the lowest possible taxonomic category. By calculating Shannon-Wiener’s and Simpson’s indexes, it’s been concluded that both locations have low diversity of species and show a uniform structure of species in both locations. By studying the gathered indicator species and their resistances to varying degrees of pollution, it’s been concluded that the state of both locations points to at least a medium level of pollution, with Drava’s water quality being of a marginally better condition.
