American Rotifer Kellicottia bostoniensis (Rousselet, 1908) (Rotifera: Brachionidae) in Reservoirs of the Upper Volga Basin

摘要

Rotifer Kellicottia bostoniensis (Rousselet), typical for North American waterbodies, was found in three reservoirs (Ivankovo, Uglich, and Sheksna) of the Upper Volga Basin in 2005-2012. The size and density of mature rotifers (＜4 thousands ind./m~3) are comparable to or smaller than in the lakes that are the probable donors of this species.
