Diatoms (Bacillariophyceae) of the Croatian Freshwater

In this paper, check-list of freshwater diatoms (Diatomeae, Bacillariophyceae) of Croatia is presented for the first time, using the available literature published in the period from 1900 to 1995. Degree of saprobity is included for all indicator species. Total of 530 taxa has been established: 378 species, 139 varieties, 13 formes, grouped in 45 genera. Species indicators of o, o-ß, and ß-mesosaprobity are predominant (86%). The most comon species in the investigated biotopes such as lakes, rivers, natural and artificial accumulations, and hot springs were: Fragilaria capucina, F. crotonensis, Synedra ulna, Diatoma vulgare, Navicula lanceolata, N. cryptocephala, N. gracilis, Nitzschia palea, Gomphonema olivaceum, Cymbella ventricosa, Meridion circulare, and Cocconeis placentula. Fresh diatom flora provides six endemic species of Croatia: Achanthes plitvicensis, Cyclotella plitvicensis, C. pevaleki, C. juriljii, Navicula jakovljevici, and N. plitvicensis.
