Comparative Analysis of Variation in Ecological Forms of Altai Osman, Oreoleuciscus potanini (Cyprinidae), in Lakes Ayrag, Khyargas, and Nogon (Western Mongolia)

Abstract

Analysis of variation in morphological characters of Potanin Altai osman, Oreoleuciscus potanini, from two freshwater and one brackish water lakes of Western Mongolia has shown that specimens of different ecological forms—herbivorous and piscivorous—form two integral and, at the level under consideration, internally indivisible units in the system of phenetic diversity of the species O. potanini.
