Bentosne silikatne alge kao pokazatelji ekološkog potencijala reke Save

Abstract

Algološko istraživanje reke Save izvršeno je tokom septembra 2011., 2012., 2014. i 2015. godine na pet lokaliteta. Identifikovano je 140 taksona bentosnih silikatnih algi, sa najzastupljenijim predstavnicima rodova Navicula, Nitzschia i Gomphonema. Dijatomni indeksi IPS i CEE, pokazuju trend smanjenja vrednosti niz tok i lošiji ekološki potencijal vodnog tela SA_1 u odnosu na vodno telo SA_2. Istraživanja fitobentosa velikih reka u Srbiji su u povoju, stoga je neophodan nastavak rada na razvijanju stabilnog sistema procene ekološkog statusa/potencijala prema zakonskoj i podzakonskoj regulativi Republike Srbije iz oblasti upravljanaja vodama, a na osnovu smernica Okvirne direktive o vodama.

Algological investigation of the Sava River was performed in September of 2011, 2012 2014 and 2015 at five sampling sites. Altogether, 140 taxa of benthic diatoms were identified, with the most diverse representatives of the genera Navicula, Nitzschia and Gomphonema. Values of diatom indices IPS and CEE had decreasing trend along the flow, and worse ecological potential of the water body SA_1 in comparison to the water body SA_2 was determined. Research on the phytobenthos of large rivers in Serbia are at the beginning, so it is necessary to continue the work on the development of a stable system of ecological status/potential assessment, according to the legislation of the Republic of Serbia in the field of water management, based on the guidelines of the WFD.
