Abstract
pecies composition and standing crops of epilithic algae were investigated at six stations in the Geum River in 1999. A total of 160 species (49 Chlorophyceae, 5 Euglenophyceae, 92 Chrysophyceae, and 14 Cyanophyceae) was identified. The standing crops of epilithic algal species ranged 17.3-776.1×10 supper(3) cells·mm supper(-2), and averaged 227.2×10 supper(3) cells·mm supper(-2). The minimum standing crops of epilithic algae was recorded in July (averaged 105.5×10 supper(3) cells·mm supper(-2)) and the maximum in November (322.0×10 supper(3) cells·mm supper(-2)). Diatoms significantly contributed to the proportion of standing crops during the investigated period. Among 17 dominant species in standing crops, Aulacoseira granulata, Cyclotella meneghiniana, Melosira varians, Navicula pupla, Nitzschia palea, Oscillatoria tenuis, Scenedesmum quadricauda, and Synedra ulna have been known as typical algal indicators for organic pollution of water. The species diversity index(H') of epilithic algal community showed the minimum in September as 1.56 and the maximum in November as 2.11.
