CHRYSOPHYCEAN STOMATOCYSTS (CHRYSOPHYTA) IN THE RESERVOIRS OF THE BUZULUKSKII BOR NATIONAL PARK (SOUTHEASTERN EUROPEAN PART OF RUSSIA)

Abstract

The data on the diversity of the stomatocysts of Chrysophyta in the reservoirs of the Buzulukskii Bor National Park are presented. The Buzulukskii Bor is located in the Orenburg and Samara Regions, southeastern European part of Russia). Ten morphotypes of the stomatocysts were identified. Among them, the stomatocyst 67, Van de Vijver et Beyens, 2000 was registered in Russia for the first time and for the third time in the world. The second locality in the world was recorded for the stomatocyst 271, Gilbert et Smolin Gilbert et al., 1997; its first find was also registered in Russia. Descriptions, electron microscopical micrographs and data on localities are provided for all revealed stomatocysts. The results complement the data on the ecology, distribution and diversity of Chrysophyta in Russia.
