Abstract:

Modern surface samples were taken in various years (2002, 2007, 2011, 2012) in Yakutia during joint Russian-German expeditions. On the one hand, longer transects were sampled along two major roads in central and southern Yakutia and in northwestern Yakutia along the Anabar and Uele rivers in 2007. On the other hand, surface samples were also taken in the respective study areas during various fieldwork activities around Tiksi in 2002, near Pokhodsk in the Kolyma Delta in 2012, and near the Kytalyk Station in the Indigirka Lowland in 2011. The species associations of modern tecamoebae were studied both at Moscow State University and during various guest researcher visits by Professor Anatoly Bobrov.
