Objectifs
Objectives of the November-December 2007 field work will be to i) document habitat use by argali during early winter months, using both direct observations and collection of fecal pellets ; ii) obtain an early season estimate of population size (based on sightings only), for comparison with DNA mark-recapture-based estimates to be done later ; iii) to obtain an estimate of lamb survival through early winter ; iv) to document range use and levels of disturbance by domestic livestock on winter range ; v) document range condition in areas used by domestic livestock and argali on winter range as well as nearby areas lacking argali and/or domestic livestock ; and vi) to collect additional fecal pellets for population size (as well as contributing data for sub-component 1, above). Objectives of the summer 2008 field work will be to : i) document habitat use by argali during early late spring and summer months, using both direct observations and collection of fecal pellets ; ii) obtain a 2nd summer season estimate of population size (based on sightings only), for comparison with DNA mark-recapture-based estimates to be done later ; iii) obtain a 2nd estimate of early lamb production (to compare with that obtained during summer 2007 ; iv) to document range use and levels of disturbance by domestic livestock on summer range ; v) document range condition in areas used by domestic livestock and argali on winter range as well as nearby areas lacking argali and/or domestic livestock ; and vi) to collect additional fecal pellets for population size (as well as contributing data for sub-component 1, above).

Descriptif
Field surveys will be performed, during which time argali locations will be documented, as well as those of livestock, herders, and other factors relevant to understanding their habitat needs and spatial distribution. Local staff will also complement these surveys during times when we cannot be in the field. Fecal pellets from argali will be collected and DNA extracted for individual identification. Mark-recapture methods will be used to estimate population size. Dietary habits of both argali and livestock will be quantified using micro-histological fragment analysis from fecal pellets.
