Abstract
Cilj ovog rada bio je odrediti sastav zajednice slatkovodnih mekušaca u rijeci Krki, a na području Roškog slapa i Skradinskog buka utvrditi njihovu gustoću, uzrastnu i funkcionalno trofičku strukturu. Tijekom istraživanja u rijeci Krki ukupno je pronađena 21 vrsta puževa i 8 vrsta školjkaša. Na najvećem broju lokaliteta pronađeni su puževi Bithynia tentaculata i Stagnicola fuscus, dok su od školjkaša najzastupljenije vrste Anodonta anatina i Unio mancus. Posebno je važan nalaz u Hrvatskoj rijetke i zakonom strogo zaštićene vrste Anisus vorticulus. Istraživanja provedena na slapištima pokazala su da najveću gustoću populacije ima vrsta B. tentaculata, 3312 jed./m2, na lokalitetu Skradinski buk-1. Analizom uzrastne strukture utvrđeno je da mlađe jedinke prevladavaju na mikrostaništima s većom brzinom strujanja vode, za razliku od odraslih jedinki koje su češće na mjestima s manjom brzinom strujanja. Provedena analiza funkcionalno trofičke strukture zajednice mekušaca pokazala je da na Skradinskom buku najveći udio imaju detritivori, zatim slijede strugači i aktivni filtratori. Na Roškom slapu dominiraju strugači, dok su aktivni filtratori i detritivori prisutni u manjem broju.
Abstract (english)
The goal of this study was to determine composition of freshwater mollusc assemblages in the River Krka and to define their density, size classes and functional feeding guilds at the area of Roški slap and Skradinski buk. In total, 21 species of snails and 8 species of mussels were found during investigation of Krka River. At most of the localities snail species Bithynia tentaculata and Stagnicola fuscus were found, while the most common species of bivalves were Anodonta anatina and Unio mancus. Very important was finding of Anisus vorticulus which is very rare and nationally protected species. The most abundant species at waterfalls was B. tentaculata which had density of 3312 ind./m2 at locality Skradinski buk 1. The analysis of size classes indicated that younger individuals prevailed at microhabitats with higher flow velocities while adult individuals were dominant in slower currents. Dominant functional feeding guild at Skradinski buk were detritivores but grazers and active filtrators were also present in significant numbers. At Roški slap, grazers were dominant while active filtrators and detritivores were present in lesser numbers.
