Abstract | ||||
Specimens of the centric benthic diatom Terpsione musica Ehrenberg species belonging to family Biddulphiaceae, collected from different aquatic habitats in Cairo, Egypt were examined using LM and SEM in order to reveal more details about frustule structure and to reconfirm its identification. Ecology of this taxon aimed to be studied. Examination of T. musica revealed that the most characteristic features of this species are the presence of pseudosepta, which appear in girdle view as musical notation (from which the species derives its name) in addition to the presence of rimportula. Reconfirmation of the identification of T. musica was carried out to remove the confusion between this species and the related one; T. americana. Ecological studies of this species indicated that; although this species was recorded in many localities in The Greater Cairo; its maximum flourishment was observed in the ground seepages of Kobri El-Kobba (i.e. T. musica is a monomorphic specialist species), which characterized by slightly alkaline, brackish hard water with relatively high electrical conductivity and moderately high temperatures. | ||||
