  Abstract Snow leopards (Panthera uncia) are an enigmatic, high-altitude species whose challenging habitat, low population densities

and patchy distribution have presented challenges for scientists studying its biology, population structure, and genetics.

Molecular scatology brings a new hope for conservation efforts by providing valuable insights about snow leopards, including

their distribution, population densities, connectivity, habitat use, and population structure for assigning conservation units.

However, traditional amplification of microsatellites from non-invasive sources of DNA are accompanied by significant

genotyping errors due to low DNA yield and poor quality. These errors can lead to incorrect inferences in the number of

individuals and estimates of genetic diversity. Next generation technologies have revolutionized the depth of information

we can get from a species' genome. Here we used double digest restriction-site associated DNA sequencing (ddRAD-seq),

a well-established technique for studying non-model organisms, to develop a reference sequence library for snow leopards

using blood samples from five Mongolian individuals. Our final data set reveals 4504 loci with a median size range of 221 bp.

We identified 697 SNPs and low nucleotide diversity (0.00032) within these loci. However, the probability that two random

individuals will share identical genotypes is about 10-168. We developed probes for DNA capture using this sequence library

which can now be used for genotyping individuals from scat samples. Genetic data from ddRAD-seq will be invaluable for

conducting population and landscape scale studies that can inform snow leopard conservation strategies.
