When? Where? and for How Long? Census Design Considerations for an Alpine Lagomorph, the Collared Pika (Ochotona collaris)

  • Shawn F. Morrison

Talus-dwelling pikas (Ochotona spp.) live in alpine areas on naturally fragmented patches of talus habitat separated by an inhospitable matrix of meadow or forest. Consequently, pikas have been studied to examine dispersal behavior (Peacock and Smith 1997) and to test predictions of metapopulation theory (Clinchy et al. 2002; Moilanen et al. 1998; Smith 1980). Their small territories, diurnal behavior, and high levels of activity have also made them the focus of studies investigating foraging behavior (Dearing 1996; Holmes 1991; Morrison et al. 2004), nutrient cycling (Aho et al. 1998), and plant community composition (Huntly 1987; Mcintire and Hik 2002), among others.
