Abstract		Abstract. Algae studies were carried out in some specific biotopes of Slovenia: eutrophic lakes (Kosečki bajer, Sotelsko jezero), peat bogs (Lovrenška jezera, Šijec), waterfalls (Savica, Krka falls, small waterfall on Pohorje), springs (springs at Medvedje Brdo and Pohorje, hot spring at Terme Čatež, mincral spring at Rimski vrelec), brackistt waters (Fiesa lake, Dragonja estuary), hypereutrophic biotopes (manure water, constructed wetlands), aerial biotopes (conerete wall, stony wall, lime tree ttunk (Tilia platyphyllos), limestone rock, Krška jama cave) and the Dragonja Rivcr. Samples were taken seasonally at 26 sampling sites in 1998, 1999, 2000 and 2001. Similarity in species structure and abundance of algae were determined with the Bray-Curtis coefficient of similarity. Altogether, 537 species and subspecies of algae (of nine classes) were determined and most of them belonged to Bacillariophyceae. 146 species and subspecies were identified for the first time in Slovenia; of Ihese 107 belonged to Bacillariophyceac, 28 to Cyanophyceae, six to Chlorophyceae, four to Zygnematophyceae and one to Xanthophyceae. The appearance of almost half of all species and subspecies was limited to a single sampling site. Eight species (Achnanthes minutissima, Cymbella affinis, Cymbella silesiaca, Gomphonema angustum, Navicula veneta, Navicula sp., Phormidiurn sp. and Trentepnhlia aurea) were present in more than half of all specitic biotopes.
Summary		Izvleček. V prispevku je predstavljena raziskava alg v nekaterih posebnih biotopih v Sloveniji: eutrofnihjezerih (Koseški bajer, Sotelskojezero), visokih bar jih (Lovrenška jezera, Šijec), slapovih (Savica, slapovi na Krki, slapič na Pohorju), izvirih (izvir na Medvedjem Brdu in Pohorju, termalni izvir v Termah Čatež, mineralni izvir Rimski vrelec), brakičnih vodah (jezero v Fiesi, izliv Dragonje), hiperevtrofnih biotopih (gnojevka, rastlinskih čistilnih napravah), kopenskih biotopih (betonski zid, kamniti rid, deblo lipe (Tilia platyphyllos), apnenčasta skala, Krška jama) in reki Dragonji. Vzorci so bili odvzeti na 26 vzorčnih mestih v letih 1998, 1999, 2000 in 2001. Z Bray-Cuttisovim koeticientom podobnosti je bila ugotovljena podobnost v vrstni strukturi in abundanci alg. Skupnoje bilo določenih 537 vrst in podvrst alg iz devetih razredov, po številu določenih vrst so prcvladovale Bacillariophyceae. 146 vrst in podvrst je bilo v Sloveniji prvič zabeleženih, od tegajih l07 pripada razredu Bacillariophyceae, 28 raa.redu Cyanophyceae, šest razredu Chlorophyceae, štiri razredu 7.ygnematophyceae in ena razredu Xanthophyceae. Pojavljanje skoraj polovice vsch določenih vrst in podvrst je bilo omejeno na posamezna vzorčna mesta. Osem vrst (Achnanthes minutissima, Cymbella affinis, Cymbella silesiaca, Gomphonema angustum Navicula veneta, Navicula sp., Phormidium sp. in Trentepohlia aurea) je bilo prisotnih v več kot polovici vseh posebnih biotopov.
