Abstract
Chrysophyte stomatocyst assemblages were described, using International Statospore Working Group (ISWG) guidelines, from a peat core from the Lena River Region of northwestern Siberia (69°23.33 N, 125°08.37 E). Cysts were well preserved, abundant, and diverse throughout the 7180 ± 110 years of peat accumulation. A total of 161 morphotypes were recorded, of which 52 are described as new. As this is only the second study of chrysophyte cysts from arctic peats, this high number of new morphotypes is not overly surprising. Marked changes in cyst assemblages occurred throughout the development of this bog, indicating that chrysophyte cysts preserved in peats may potentially provide important paleoenvironmental proxy data.
