Abstract

Epipelic diatom communities were studied in the Šerićka bara marsh in northeast Bosnia and Herzegovina throughout 2009. During spring and summer a total of 57 species was found at 6 sampling points. The highest number of species was noted for genera Gomphonema (8) and Nitzschia (5). The most abundant species were Melosira varians C.Agardh, Gyrosigma acuminatum (Kützing) Rabenhorst, Lemnicola hungarica (Grunow) F.E.Round & P.W.Basson, Navicula cryptocephala Kützing, Cocconeis placentula var. placentula Ehrenberg, Hippodonta capitata (Ehrenberg) Lange-Bertalot, Metzeltin & Witkowski, Fallacia pygmaea (Kützing) A.J.Stickle & D.G.Mann, Anomoeoneis sphaerophora E.Pfitzer, Craticula cuspidata (Kutzing) D.G.Mann, Cyclotella meneghiniana (Kutzing) D.G.Mann and Tryblionella hungarica (Grunow) Frenguelli. The spatial variation of the epipelic community was higher in summer as summarized by PCO analysis. Values of the Shannon-Wiener Diversity Index ranged from 2.47 to 2.96, while the Rott Trophic Index ranged from 2.7 to 3.4. Most of the species were eutraphentic (61%) and alkaliphilous (60%), indicating the eutrophic and polytrophic status of this wetland.
