    Between 1998 and 2000, microplanktonic and microbenthic algal communities were sampled and analysed in the coastal lake Fiesa and in the Dragonja estuary. The purpose of the investigation was to establish qualitative composition and the relative abundance of algal communities. In 1999 and 2000, basic physical and chemical parameters were measured. Altogether, 159 algal taxa were determined, 83 in the coastal lake Fiesa and 120 in the Dragonja estuary. Most of the taxa belonged to the Bacillariophyceae. Thirty four percent of all taxa were typical brackish taxa. Achnanthes septata, Amphora angusta, Gyrosigma tenuissimum, Gyrosigma wansbeckii and Pleurosigma strigosum (all Bacillariophyceae) were marine species. Brackish and marine taxa were almost exclusively Bacillariophyceae. Nineteen taxa were the first citations for Slovenia, 15 of them belonging to the Bacillariophyceae and four to the Cyanophyceae. Most new taxa belong to the genus Navicula (4).U razdoblju od 1998. do 2000. uzorkovane su i analizirane mikroplanktonske i mikrobentoske zajednice algi u obalnom jezeru Fiesa i na ušću Dragonje. Cilj istraživanja bio je ustanoviti kvalitativni sastav i relativnu abundanciju zajednica algi. Osnovni fizikalni i kemijski parametri mjereni su 1999. i 2000. Utvrđeno je 159 svojta algi, 83 u jezeru Fiesa te 120 u ušću Dragonje. Većina taksona pripadala je porodici Bacillariophyceae, a 34% od ukupnog broja bile su tipične vrste boćatih voda. Morske vrste bile su Achnanthes septata, Amphora angusta, Gyrosigma tenuissimum, Gyrosigma wansbeckii i Pleurosigma strigosum (sve Bacillariophyceae). Boćati i morski taksoni bili su gotovo isključivo Bacillariophyceae. Po prvi puta za Sloveniju zabilježeno je 19 svojti, 15 iz porodice Bacillariophyceae i 4 iz porodice Cyanophyceae. Većina novih svojti pripada rodu Navicula (4)

    Algal occurrence, with particular emphasis on diatoms, was investigated over a two-year period on the travertine barriers of the Krka River in Slovenia. The purpose of the investigation was to establish qualitative composition and the relative abundance of the periphyton. In 1999 and 2000, basic physical and chemical parameters were measured. Altogether, 81 algal taxa were determined. Most of them belonged to Bacillariophyceae. Fifteen species and subspecies were new to Slovenia, 14 of them belonging to Bacillariophyceae and one to Cyanobacteria. Most of the new species and subspecies belonged to genera Nitzschia (5) and Navicula (4).Tijekom dvije godine istraživana je prisutnost algi s posebnim naglaskom na dijatomeje na sedrenim barijerama rijeke Krke u Sloveniji. Cilj je bio utvrđivanje kvalitativnog sastava i relativne brojnosti perifitona. Tijekom 1999. i 2000. mjereni su temeljni fizikalni i kemijski parametri. Utvrđen je 81 takson algi. Većina pripada u Bacillariophyceae. Petnaest vrsta i podvrsta bilo je novo za Sloveniju, od čega 14 spada u Bacillariophyceae i 1 u Cyanobacteria. Većina novih vrsta i podvrsta pripadalo je rodovima Nitzschia (5) i Navicula (4)

    In the years 1998, 1999 and 2000, samples were taken seasonally in the peat bogs of Lovren{ka jezera and [ijec. The purpose of the investigation was to establish the qualitative species structure and abundance of the periphyton and the phytoplankton. The paper presents the first complete algological research in this area. In the year 1999, some physical and chemical parameters were also measured. Altogether, 116 species and subspecies of algae were determined. Most of them belonged to Bacillariophyceae, followed by Conjugatophyceae and Cyanobacteria. 17 species and subspecies are new to Slovenia, most of them belonging to Bacillariophyceae.Iz cretova Lovrenška jezera i Šijec sezonski su uzimani uzorci tijekom 1998., 1999. i 2000. Cilj istraživanja bio je utvrditi kvalitativni sastav vrsta i brojnost perifitona i fitoplanktona. Rad prikazuje prvo cjelovito algološko istraživanje tog područja. Tijekom 1999. mjereni su i neki fizikalni i kemijski parametri. Ukupno je determinirano 116 vrsta i podvrsta algi. Većina je pripadala skupini Bacillariophyceae, slijedile su Conjugatophyceae i Cyanobacteria. Sedamnaest vrsta je novih za Sloveniju, a uglavnom su iz skupine Bacillariophyceae
