Six aquatic gastropod species were identified, including <em>Bosnidilhia vreloana </em>Boeters, Glöer &amp; Pešić, 2013 and <em>Islamia dmitroviciana </em>Boeters, Glöer &amp; Pešić, 2013, two species endemic for the studied area. Surprisingly, we did not observe a significant influence of discharge on the composition of gastropod assemblages in the studied springs. This could mean that gastropod assemblages in the springs examined are well adapted to intermittent conditions (i.e. fluctuations in discharge). The results of canonical correspondence analysis (CCA) showed that specific substrate types can be good predictors for the occurrence of particular species. Interestingly, we found that spring specialists such as <em>Bythinella schmidti</em> and <em>Islamia dmitroviciana </em>also inhabit springs with intermittent dry periods. The studied springs should be considered at risk and some of their gastropod dwellers, such as the endemics <em>Bosnidilhia vreloana</em> and <em>Islamia dmitroviciana</em>, are possibly endangered, requiring conservation planning to protect these spring habitats.</p><p> </p><p><strong>Key words:</strong> springs; intermittent springs, gastropods; discharge; substrate types</p><p> </p><div><p><strong>Received: </strong>October 9, 2015; <strong>Revised:</strong> November 3, 2015; <strong>Accepted:</strong> November 10, 2015; <strong>Published online:</strong> May 23, 2016</p></div> ER -
