First finding of a genus Haslea Simonsen in Serbia and new diatom taxa for the country's flora in extreme and unique habitats in the Vojvodina Province

Abstract

Salt habitats are extreme and unique environments found from Austria through Hungary to the Vojvodina Province in Serbia. In our study, we investigated eight saline habitats (channeled salt marshes, moist salt meadows and saline ponds), from which we collectedplankton, epipelic and epiphytic diatoms. Seventeen diatom taxa new for the Serbian diatom flora were recorded. In addition, the genus Haslea, with one species (H. spicula), was recorded for the first time in Serbia. The identified taxa were sporadic or rare in the samples.

Alkalna slana jezera, bare i močvare su ekstremna i jedinstvena staništa rasprostranjena u Austriji, Mađarskoj i Srbiji (Vojvodina). Istraživanje je obuhvatilo osam slanih staništa različitog tipa: kanalizovane slatine, zabarena slana staništa i slane bare. Uzorci obuhvataju različite zajednice silikatnih algi: plankton, bentos i epifite. Utvrđeno je prisustvo 17 taksona silikatnih algi po prvi put zabeleženih na teritoriji Srbije, a među njima prvi put i rod Haslea Simonsen sa jednom vrstom, H. spicula. Identifikovani taksoni su retki i sporadično nalaženi u uzorcima.
