Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA LAGOMORPHA OCHOTONIDAE

Scientific Name: Ochotona turuchanensis
Species Authority: Naumov, 1934
Common Name(s):
English Turuchan Pika
Taxonomic Notes: There are no recognized subspecies (Hoffmann and Smith 2005). This form has recently been acknowledged as a distinct species (Hoffmann and Smith 2005). It was formerly listed as a subspecies of Ochotona hyperborea (Sokolov et al. 1994), while others have listed it as a subspecies O. alpina (Formozov and Yakhontov 2003). There is some dispute regarding the listing of O. turuchanensis as a distinct species (Formozov and Yakhontov 2003). Formozov and Yakhontov (2003) contend that the differences between it and O. alpina ("summer and winter plumage and some aspects of its alarm call") are insufficient for species distinction (Formozov and Yakhontov 2003). A recent molecular phylogenetic study supports species level distinction for O. turuchanensis (Lissovsky et al. 2007).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Smith, A.T. & Johnston, C.H.
Reviewer(s): Boyer, A.F. & Johnston, C.H. (Lagomorph Red List Authority)
Justification:
As a recently acknowledged species, Ochotona turuchanensis had not been previously assessed. It is a widespread species, but very little is known about its current status. It is reported as abundant on the Putorana plateau in Russia (Lissovsky pers. comm.).
History:
2003 Not Evaluated (IUCN 2003)
2003 Not Evaluated

Geographic Range [top]

Range Description: The geographic distribution of Ochotona turuchanensis extends from the southern expanse of the Yenesei River to Lake Baikal and the middle region of the Lena River in Russia (Hoffmann and Smith 2005). O. turuchanensis is "widely sympatric with O. hyperborea over much of its range" (Hoffmann and Smith 2005).

Population [top]

Population: There are few data on the current population status of this species. On the Putorana plateau in Siberia, Russia, Ochotona turuchanensis is considered abundant (Lissovsky pers. comm.)
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Ochotona turuchanensis is a rock-dwelling species of pika (Lissovsky pers. comm.). This is an herbivore that demonstrates preference in which plants it consumes (Lissovsky 2004). It is diurnal, avoiding nighttime activity due to low temperatures (Lissovsky 2004). Reproductive periodicity extends from mid-June through late August (Lissovsky 2004). Females have 3.4 ± 1.4 (n=8) embryos (Lissovsky 2004). Juveniles begin to appear in mid-July (Lissovsky 2004). Total length of the species is 15.8-19.0 cm (Lissovsky 2004).
Systems: Terrestrial

Threats [top]

Major Threat(s): The threats to this species are not known.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures in place for this species. Research should be conducted to determine the current population status, as little data are available in this area. Furthermore, more data are needed regarding the biology and ecology of Ochotona turuchanensis.
