Mycrophytobenthos communities in the fresh water ecosystems of the Trsteno Arboretum (Southern Croatia)

The microphytobenthos from the fresh water of Trsteno Arboretum consisted of 84 species, mostly diatoms (55 species). There were 15 representatives of Chlorophyceae and 10 cyanobacteria, as well as scattered representatives of Schizomycetes, Xanthophyceae and Mycota. Five diatoms were present throughout the research period: Achnanthes affinis Grun., A. microcephala Grun., Cocconeis placentula Ehr., Synedra ulna Ehr., and Gomphonema dichotomum Kütz. The maximal number of species was detected during the winter and spring, and the minimum number in autumn. The saprobic index, based on the characteristic species determined in the benthic community (ranging from 1.7 to 2.2) indicated moderate impurity.
