Silica-scaled chrysophytes during spring in the Kis-Balaton Reservoir, Hungary
As a result of taking water samples in spring 1999, 26 species of silica-scaled chry sophytes were found in the Kis-Balaton Reservoir I, one of the most remarkable aquatic habitats in Hungary. From them, 23 have been identified with certainity, two were ques tionable and two were identified to genus level. 12 species are new to Hungary and 19 spe cies had not been found in Kis-Balaton before...
متن کاملBiodiversity and biogeographical implications of silica-scaled chrysophytes (Chrysophyceae and Synurophyceae) of the northeast wetlands of Argentina
Wetlands and water bodies in the Parana Delta River and Ibera System of northeast Argentina were studied for scaled chrysophytes. The Delta region of the Parana River is composed of a series of braided channels, streams and lagoons that extend over 17,500km2. Although the Delta is situated in the temperate zone, it experiences a more subtropical climate. The water ways of the Ibera System consi...
متن کاملBiogeographic patterns in scaled chrysophytes from the east coast of North America
1. We assessed the distribution of scaled chrysophytes in fresh waters along 3200 km of the east coast of North America (29 to 48 N) to determine any biogeographic patterns in relation to chemical, physical, climatic and spatial variables. 2. Scaled chrysophytes were identified using scanning electron microscopy and counted from 264 waterbodies in nine regions (20 subregions). Eighteen chemical...
متن کاملScaled chrysophytes in Middle Eocene lake sediments from Northwestern Canada, including descriptions of six new species
Although chrysophyte stomatocysts have a fossil record that likely extends to the lower Cretaceous, to date neither scales nor bristles of the scaled chrysophyte genera older than Holocene have been reported. This leaves the origin of this important group of freshwater algae a mystery. We discovered abundant and diverse scaled chrysophyte microfossils in ca. 47 Ma sediments (Middle Eocene, Lute...
متن کاملAn inventory of scaled chrysophytes from North Carolina, USA, and their relationships to environmental variables
The distributions of silica-scaled chrysophytes in 27 freshwater ponds from three primary regions located along the Atlantic Coastal Plain of North Carolina, USA, relative to chemical gradients are described. Phytoplankton, periphyton, and surface sediments from each of the 27 sites were collected in May and June of 2001 and later analyzed extensively with both scanning electron microscopy (SEM...
