Abstract

U razdoblju tijekom svibnja i lipnja 2018. godine vršeno je određivanje kvantitativnog i kvalitativnog sastava makrozoobentosa potoka Markuševec, u cilju prikupljanja i determinacije makroskopskih beskralježnjaka za utvrđivanje kvalitete vode metodom bodovanja. Bentosni organizmi su pouzdani pokazatelji kvalitete voda. Radom na terenu prikupljen je uzorak koji je analiziran i determiniran u laboratoriju uz pomoć kvalificirane literature. Korištena je analiza koja uključuje procjenu broja pojedinih taksona makrozoobentosa po jedinici površine vode. Metoda se temelji na činjenici da su životne zajednice odraz obilježja, odnosno kakvoće vode u kojoj obitavaju. Ova metoda daje informacije o bogatstvu i distribuciji pojedinih vrsta. Potok je bogat vrstama različitih karakteristika i osobina. Pronađene vrste obuhvaćaju redove Arthropodae, Annelidae, Molluscae. Promjene fizikalnih i kemijskih osobina mogu biti presudne za biomasu i biodiverzitet bentosa. Biološkom metodom bodovanja i determinacijom prikupljenih uzoraka utvrđena je kvaliteta i kakvoća vode potoka Markuševec. Klasifikacija uzoraka prema biotičkom bodovnom indeksu i organskom onečišćenju pokazuje da je potok u velikoj mjeri onečišćen.

Abstract (english)

During the period of May and June 2018, determination of the quantitative and qualitative composition of the macrozoobenthos of the Markuševec stream was carried out in order to determine the water quality of the stream by scoring method. Benthic organisms are reliable water quality indicators. On the field work a sample was analyzed and determined in the laboratory with the help of qualified literature. An analysis was used that included the estimation of the number of taxa per macrozoobenthos per unit of water surface. The method is based on the fact that living communities are a reflection of the characteristics or the quality of the water they live in. This method provides information on the wealth and distribution of particular species. The stream is rich in species of different characteristics and traits. The found species include ranks of Arthropodae, Annelidae, Molluscae. Changes in physical and chemical properties can be crucial for biomass and biodiversity benthos. Biological scoring method and determination of the collected samples determined the quality and quality of the water stream Markuševec. Classification of samples according to the biotic point index and organic contamination shows that the stream is largely contaminated.
