Abstract
Uzorci perifitona, uz istovremeno mjerenje fizikalno-kemijskih čimbenika, prikupljeni su tijekom osam ljetnih tjedana 2010. u sedmodnevnim intervalima ekspozicije umjetnih podloga (predmetna stakalca) te s prirodne kamene podloge iz područja bržeg i sporijeg toka vode u izvorištima. Utvrđena je značajna sličnost u dijatomejskom sastavu između istraživanih izvora bez obzira na vrstu i dinamiku naseljavanja obraštajne podloge i brzinu strujanja vode te na stabilne i slične fizikalno-kemijske čimbenike. U obraštaju s prirodne podloge ukupno je određeno 113 svojti dijatomeja, a u obraštaju s umjetne podloge 98. Vrste Achnanthidium minutissimum (Kütz.) Czarnecki i Cocconeis placentula Ehrenberg dominiraju kroz cijelo istraživano razdoblje. Izračunati visoki stupanj trofije dobiven korištenjem Rottovog trofičkog indeksa dijatomeja pokazao se neprimjerenim za izvorišna područja. Zbog toga se preporučuje putem interkalibracije dijatomejskih vrsta u odnosu na količinu fosfora redefinirati trofičke indekse dijatomeja s ciljem bolje procjene ekološkog statusa izvorišnih područja.
Abstract (english)
Periphyton samples, with simultaneous measurement of physical and chemical variables, were collected during eight summer weeks in 2010, in seven-day intervals exposure of artificial substrates (glass slides) and from natural rock substrate from the area of faster and slower water flow. The conducted researches indicate high similarity in diatom composition among the springs, regardless of type and dynamics of colonization of the fouling surface as well as water flow velocity and stable physical and chemical factors. A total of 113 diatom taxa were found in the natural substrate fouling, and 98 in the artificial substrate fouling. Species Achnanthidium minutissimum (Kütz.) Czarnecki and Cocconeis placentula Ehrenberg dominate throughout the whole research period. The calculated high trophic level, obtained by using Rott's trophic diatom index, proved to be unsuitable for the spring areas, therefore it is recommended to redefine trophic diatom indices, by intercalibration of diatom species, in relation to the concentration of phosphorus, in order to have better assessment of the ecological status of the spring habitats.
