%X a taxonomic study is presented of the predominant periphytic diatoms from three streams, nazar谷, guaiap車 and remo, influenced by different anthropogenic actions. samples were taken bimonthly in three sites of the stream watercourse, headwater, middle and mouth, from july 2007 to august 2008. twenty six predominant species was recorded, from a total of 151 identified diatoms in the analyzed samples. seven species were abundant or dominant in the three studied streams: eolimna minima (grunow) lange-bertalot (dominant in remo stream), gomphonema lagenula k邦tzing (dominant in guaiap車 stream), gomphonema pumilum (grunow) reichardt & lange-bertalot and nupela praecipua (reichardt) reichardt (both dominant in nazar谷 stream), geissleria aikenensis (patrick) torgan & oliveira, nitzschia palea (k邦tzing) smith and sellaphora seminulum (grunow) mann (abundant in three streams). two species were abundant exclusively in nazar谷 urban stream, 13 in remo rural streams and six in guaiap車 stream that is influenced by both environments.
