discussion · Plazi

According to mtDNA and nDNA, O. turuchanensis belongs to subgenus Pika. It was described as a subspecies of O. hyperborea and was not considered as a separate taxon for a long time. Due to strong morphological similarity with O. Tatetion, O. turuchanensis was not even listed as a subspecies. Peculiarity of O. turuchanensis was discovered based on qualitative morphological traits and particular bioacoustic repertoire. Further study of mtDNA showed that O. turuchanensis is a sister taxon of O. alpina and not related to O. hyperborea . Both mtDNA and nDNA studies confirmed that O. turuchanensis is closely related to O. alpina , if a species at all. Placement of O. turuchanensis into O. alpina does not explain, however, its morphological similarities to O. hyperborea and its particular ecological preferences. Before merging these two taxa, a hypothesis about hybrid origin of O. turuchanensis should be tested. Ochotona turuchanensis is sympatric with O. hyperborea in the Putorana Plateau and adjacent regions of the central Siberian Plateau in the Nizhnyaya Tunguska River Basin. Monotypic.

Movements, Home range and Social organization. The Turuchan Pika moves aboveground by running and leaping openly. Preferred locations are used for sunbathing. Home ranges were 2300-3500 m* in one study. Home ranges of males and females slightly overlap. Densities are 7-240 ind/km?®. Areas occupied are marked with old hay piles and latrines. Special markings are characteristic of the Turuchan Pika: piles offecal pellets, surrounded by red crustose lichen. The Turuchan Pika has well-developed vocalizations, including alarm calls and songs. Its song resembles that of the Alpine Pika, but time-frequency curves of song elements are very different. Nests of Turuchan Pikas are situated under stones.
