title: Assessment of the Species Diversity of the Genus Pseudo-nitzschia H. Peragallo, 1900 (Bacillariophyta) in Plankton near Karadag Using Multidimensional Statistical Analysis
abstract: More than 50 species are known in the genus Pseudo-nitzschia H. Peragallo, 1900. Seven of them were recorded in the Black Sea. Due to the high morphological similarity, many representatives of the genus are considered to be cryptic; their reliable identification requires the use of different, often very resource-consuming methods. The aim of this study was to estimate the total number of Pseudo-nitzschia species occurring near Karadag (southeastern Crimea) during the period of their mass develop
