  Title Characterization of 9 microsatellites and primers in snow leopards and a species-specific PCR assay for identifying noninvasive samples Type Journal Article
  Year 2014 Publication Conservation Genetic Resource Abbreviated Journal  
  Volume 6 Issue 2 Pages 369:373  
  Keywords Microsatellites,Cytochrome b, Snow Leopard, Noninvasive genetics, Individual identification  
  Abstract Molecular markers that can effectively identify noninvasively collected samples and provide genetic

information are critical for understanding the distribution, status, and ecology of snow leopards (Panthera uncia). However, the low DNA quantity and quality in many

noninvasive samples such as scats makes PCR amplification and genotyping challenging. We therefore designed primers for 9 microsatellites loci previously isolated in the

domestic cat (Felis catus) specifically for snow leopard studies using noninvasive samples. The loci showed moderate levels of variation in two Mongolian snow leopard

populations. Combined with seven other loci that we previously described, they have sufficient variation (He = 0.504, An = 3.6) for individual identification and

population structure analysis. We designed a species species specific PCR assay using cytochrome b for identification of unknown snow leopard samples. These molecular markers

facilitate in depth studies to assess distribution, abundance, population structure, and landscape connectivity of this endangered species.

  Title Threatened cats of Asia Type Journal Article
  Year 1978 Publication Wildlife Abbreviated Journal  
  Volume 20 Issue 9 Pages 396-400  
  Keywords Asia, Acinonyx jubatus, Asiatic cheetah, cheetah, Siberian tiger, snow leopard  
  Abstract Man's hand is turned against the wild cats wherever they occur, often due to the value of their fur, but also because of the danger they sometimes pose to domestic stock and even human beings. All the larger Asian cats are threatened, and on this and the following pages we look at three of them – the Asiatic cheetah, the Siberian tiger, and the snow leopard.

  Title Estimating snow leopard density using fecal DNA in a large landscape in north-central Nepal Type Journal Article
  Year 2019 Publication Global Ecology and Conservation Abbreviated Journal  
  Volume Issue 17 Pages 1-8  
  Keywords Panthera uncia, Density, Annapurna-Manaslu landscape, Noninvasive, Spatial scale  
  Abstract Although abundance estimates have a strong bearing on the conservation status of a

species, less than 2% of the global snow leopard distribution range has been sampled

systematically, mostly in small survey areas. In order to estimate snow leopard density

across a large landscape, we collected 347 putative snow leopard scats from 246 transects

(490 km) in twenty-six 5  5km sized sampling grid cells within 4393 km2 in Annapurna-

Manaslu, Nepal. From 182 confirmed snow leopard scats, 81 were identified as belonging

to 34 individuals; the remaining were discarded for their low (<0.625) quality index. Using

maximum likelihood based spatial capture recapture analysis, we developed candidate

model sets to test effects of various covariates on density and detection of scats on transects.

The best models described the variation in density as a quadratic function of

elevation and detection as a linear function of topography. The average density estimate of

snow leopards for the area of interest within Nepal was 0.95 (SE 0.19) animals per 100 km2

(0.66e1.41 95% CL) with predicted densities varying between 0.1 and 1.9 in different parts,

thus highlighting the heterogeneity in densities as a function of habitat types. Our density

estimate was low compared to previous estimates from smaller study areas. Probably,

estimates from some of these areas were inflated due to locally high abundances in overlap

zones (hotspots) of neighboring individuals, whose territories probably range far beyond

study area borders. Our results highlight the need for a large-scale approach in snow

leopard monitoring, and we recommend that methodological problems related to spatial

scale are taken into account in future snow leopard research.

  Title Ungulate spatiotemporal responses to contrasting predation risk from wolves and snow leopards Type Journal Article
  Year 2022 Publication Journal of Animal Ecology Abbreviated Journal  
  Volume Issue Pages 1-16  
  Keywords landscape of fear, multiple-predator effects, non-consumptive effects, predation-risk effects, predator facilitation, risk allocation, snow leopard, wolf  
  Abstract 1. Spatial responses to risk from multiple predators can precipitate emergent consequences for prey (i.e. multiple-predator effects, MPEs) and mediate indirect interactions between predators. How prey navigate risk from multiple predators may therefore have important ramifications for understanding the propagation of predation-risk effects (PREs) through ecosystems.

2. The interaction of predator and prey traits has emerged as a potentially key driver of antipredator behaviour but remains underexplored in large vertebrate systems, particularly where sympatric prey share multiple predators. We sought to better generalize our understanding of how predators influence their ecosystems by considering how multiple sources of contingency drive prey distribution in a multi-predator–multi-prey system.

3. Specifically, we explored how two sympatric ungulates with different escape tactics—vertically agile, scrambling ibex Capra sibirica and sprinting argali Ovis ammon—responded to predation risk from shared predators with contrasting hunting modes—cursorial wolves Canis lupus and vertical-ambushing, stalking snow leopards Panthera uncia.

4. Contrasting risk posed by the two predators presented prey with clear trade-offs. Ibex selected for greater exposure to chronic long-term risk from snow leopards, and argali for wolves, in a nearly symmetrical manner that was predictable based on the compatibility of their respective traits. Yet, acute short-term risk from the same predator upended these long-term strategies, increasing each ungulates' exposure to risk from the alternate predator in a manner consistent with a scenario in which conflicting antipredator behaviours precipitate risk-enhancing MPEs and mediate predator facilitation. By contrast, reactive responses to wolves led ibex to reduce their exposure to risk from both predators—a risk-reducing MPE. Evidence of a similar reactive risk-reducing effect for argali vis-à-vis snow leopards was lacking.

5. Our results suggest that prey spatial responses and any resulting MPEs and prey-mediated interactions between predators are contingent on the interplay of hunting mode and escape tactics. Further investigation of interactions among various drivers of contingency in PREs will contribute to a more comprehensive understanding and improved forecasting of the ecological effects of predators.

  Title Genetic diversity and spatial structures of snow leopards (Panthera uncia) reveal proxies of connectivity across Mongolia and northwestern China Type Journal Article
  Year 2022 Publication Landscape Ecology Abbreviated Journal  
  Volume Issue Pages 1-19  
  Keywords Admixture · Central Asia · Connectivity · Habitat Modeling · Landscape Genetics · Noninvasive Genetics · MEM · Spatial Structures  
  Abstract Understanding landscape connectivity and population genetic parameters is imperative for threatened species management. However, such information is lacking for the snow leopard (Panthera uncia). This study sought to explore hierarchical snow leopard gene flow patterns and drivers of genetic structure in Mongolia and China. A total of 97 individuals from across Mongolia and from the north-eastern edge of the Qinghai-Tibetan Plateau in Gansu Province to the middle of Qinghai Province in China were genotyped across 24 microsatellite loci. Distance-based frameworks were used to determine a landscape scenario best explaining observed genetic structure. Spatial and non-spatial methods were used to investigate fine-scale autocorrelation and similarity patterns as well as genetic structure and admixture. A genetic macro-division between populations in China and Mongolia was observed, suggesting that the Gobi Desert is a substantial barrier to gene flow. However, admixture and support for a resistance-based mode of isolation suggests connective routes that could facilitate movement. Populations in Mongolia had greater connectivity, indicative of more continuous habitat. Drivers of genetic structure in China were difficult to discern, and fine-scale sampling is needed. This study elucidates snow leopard landscape connectivity and helps to prioritize conservation areas. Although contact zones may have existed and occasional crossings can occur, establishing corridors to connect these areas should not be a priority. Focus should be placed on maintaining the relatively high connectivity for snow leopard populations within Mongolia and increasing research efforts in China.

  Abstract Snow leopards (Panthera uncia) are elusive endangered carnivores found in remote mountain regions of Central Asia. New methods for identifying and counting snow leopards are needed for conservation and management efforts. To develop molecular genetic tools for individual identification of hair and faecal samples, we screened 50 microsatellite loci developed for the domestic cat (Felis catus) in 19 captive snow leopards. Forty-eight loci were polymorphic with numbers of alleles per locus ranging from two to 11. The probability of observing matching genotypes for unrelated individuals (2.1 x10-11) and siblings (7.5x10-5) using the 10 most polymorphic loci was low, suggesting that this panel would easily discriminate among individuals in the wild.

  Title Research in Nondomestic Species: Experiences in Reproductive Physiology Research for Conservation of Endangered Felids Type Miscellaneous
  Year 2003 Publication ILAR Journal Abbreviated Journal  
  Volume 4 Issue Pages 307-316  
  Keywords artificial insemination; capacity building; catmodels; cryopreservation; electroejaculation; embryo transfer; mobile laboratory; nondomestic felids  
  Abstract Tremendous strides have been made in recent years to broaden our understanding of reproductive processes in nondomestic felid species and further our capacity to use this basic knowledge to control and manipulate reproduction of endangered cats. Much of that progress has culminated from detailed scientific studies conducted in nontraditional laboratory settings, frequently at collaborating zoological parks but also under more primitive conditions, including in the field. A mobile laboratory approach is described, which incorporates a diverse array of disciplines and research techniques. This approach has been extremely useful, especially for conducting gamete characterization and function studies as well as reproductive surveys, and for facilitating the development of assisted reproductive technology. With continuing advances in assisted reproduction in rare felids, more procedures are being conducted primarily as service-related activities, targeted to increase effectiveness of species propagation and population management. It can be a challenge for both investigators and institutional animal care and use committees (IACUCs) to differentiate these service-based procedures from traditional research studies (that require IACUC oversight). For research with rare cat species, multi-institutional collaboration frequently is necessary to gain access to scientifically meaningful numbers of study subjects. Similarly, for service-based efforts, the ability to perform reproductive procedures across institutions under nonstandard laboratory conditions is critical to applying reproductive sciences for managing and preserving threatened cat populations. Reproductive sciences can most effectively assist population management programs (e.g., Species Survival Plans) in addressing conservation priorities if these research and service- related procedures can be conducted “on the road” at distant national and international locales. This mobile laboratory approach has applications beyond endangered species research, notably for other scientific fields (e.g., studies of hereditary disease in domestic cat models) in which bringing the laboratory to the subject is of value.

  Title Seasonal effects on ovarian responsiveness to exogenous gonadotrophins and successful artificial insemination in the snow leopard (Uncia uncia) Type Journal Article
  Year 1997 Publication Reprod Fertil Dev Abbreviated Journal  
  Volume 9 Issue 3 Pages 285-295

  Abstract Ovaries of the seasonally-breeding snow leopard (Uncia uncia) were examined to determine whether they were responsive to exogenous gonadotrophins throughout the year. The potential of laparoscopic artificial insemination (AI) also was assessed for producing offspring. During the non-breeding, pre-breeding, breeding and post-breeding seasons, females (n = 20) were treated with a standardized, dual- hormone regimen given intramuscularly (600 I.U. of equine chorionic gonadotrophin followed 80-84 h later with 300 I.U. of human chorionic gonadotrophin (hCG)). Laparoscopy was performed 45-50 h after administration of hCG, and all ovarian structures were described. Females with fresh corpora lutea (CL) were inseminated, and anovulatory females were subjected to follicular aspiration to examine oocyte quality. Snow leopards responded to exogenous gonadotrophins throughout the year. Mean number of total ovarian structures (distinct follicles mature in appearance plus CL) did not differ (P > or = 0.05) with season, but the proportion of CL: total ovarian structures was greater (P < 0.01) for the breeding season compared with all other seasons. The proportion of females ovulating was greater (P < 0.05) during the breeding and post-breeding seasons than during the pre-breeding and non- breeding seasons respectively. No Grade-1 quality oocytes were recovered from follicles of anovulatory females. Serum concentrations of oestradiol-17 beta appeared elevated in all females, and neither oestradiol-17 beta concentrations nor progesterone concentrations differed (P > or = 0.05) among seasons. Of 15 females artificially inseminated, the only one that was inseminated in the non-breeding season became pregnant and delivered a single cub. This is the first successful pregnancy resulting from AI in this endangered species.

  Title Function and culture requirements of snow leopard (Panthera uncia) spermatozoa in vitro Type Journal Article
  Year 1994 Publication J Reprod Fertil Abbreviated Journal  
  Volume 101 Issue 3 Pages 563-569  
  Keywords Animal; Carnivora; physiology; Cell; survival; Cells; Cultured; Comparative; study; Culture; Media; Female; Male; Pentoxifylline; Sperm; Motility; Ovum; Interactions; Spermatozoa; cytology; Support; Non-U.S.Gov't; U.S.Gov't; P.H.S.; browse; non; us; gov't; government; 190  
  Abstract Electroejaculates from eight snow leopards were used to determine how the motility of spermatozoa was influenced by (i) type of media (Ham's F10, PBS, human tubal fluid or RPMI-1640); (ii) holding temperature (23 degrees C versus 37 degrees C); (iii) washing of spermatozoa and (iv) a sperm metabolic enhancer, pentoxifylline. The duration of sperm motility was assessed by evaluating samples in each treatment every hour for 6 h and a sperm motility index (a value combining percentage sperm motility and rate of forward progression) calculated. Spermatozoa from the Ham's F10, PBS and PBS plus pentoxifylline treatments were also co-incubated with zona-intact, domestic cat eggs that were fixed and evaluated for spermatozoa bound to the zona pellucida, penetrating the outer and inner layers of the zona pellucida and within the perivitelline space. During the 6 h co-incubation, the sperm motility index in PBS with pentoxifylline was greater (P < 0.05) than in PBS alone which, in turn, was greater (P < 0.05) than in the other three test media. Washing the spermatozoa enhanced (P < 0.05) motility in both PBS and PBS plus pentoxifylline relative to unwashed samples, but there was no effect (P > 0.05) of holding temperature. Pentoxifylline supplementation enhanced (P < 0.05) the proportion of cat eggs with bound, but not penetrated, snow leopard spermatozoa in the inner layer of the zona pellucida, and there were no spermatozoa in the perivitelline space.(ABSTRACT TRUNCATED AT 250 WORDS)
