The diatom genus Tetracyclus (Fragilariaceae, Bacillariophyta) from Chile

چکیده
Consequently the name Biblarium chilense is a nomen nudum. Even so, some years later De Toni, observing neither illustration nor specimen, transferred it to Tetracyclus as Tetracyclus (chilensis) chilense (Ehrenb.) De Toni (De Toni 1892: 749). Regardless of these nomenclatural details, that a species of Tetracyclus was found in Chile offered data of potential biogeographic interest (Williams 2004) and Ehrenberg’s comparison with Tetracyclus compressum (Ehrenb.) M. Peragallo (in Héribaud 1893: 159; basionym: Biblarium compressum Ehrenberg 1843: 73) prompted the following remarks:

The diatom Brachysira gravida Shayler & Siver sp. nov. is described from an oligotrophic, acidic, freshwater lake in the Ocala National Forest in north-central Florida, U.S.A. The richness of Brachysira was previously investigated to reveal that the genus is both abundant and morphologically diverse in this region of Florida and is therefore of particular taxonomic interest. Valves of Brachysir...
متن کاملIdentification of Diatoms (Bacillariophyceae) during Ecological Assessments: Comparison between Light Microscopy and Scanning Electron Microscopy Techniques
Identification of diatom frustules, a vital step during ecological analyses, is greatly influenced by the magnification at which samples are examined. The striking differences between Light Microscopy (LM) and Scanning Electron Microscopy (SEM) reveal inconsistencies in the identification of diatoms at low magnifications. These inconsistencies hinder comparative analyses between data sets colle...

The diatom composition on some Charophyceae taxa was investigated in different freshwater ecosystems in Bosnia and Herzegovina, Croatia and Montenegro during 2007. A total of 91 taxa belonging to 37 genera were identified. The genus Gomphonema with 9 taxa was the most diverse, followed by Navicula (7), Nitzschia, Pinnularia and Gyrosigma (5). The number of taxa at the localities varied from nin...
