  Title Landscape resistance to gene flow in a snow leopard population from Qilianshan National Park, Gansu, China Type Journal Article
  Year 2023 Publication Landscape Ecology Abbreviated Journal  
  Volume Issue Pages  
  Keywords Landscape genetics · MLPE · Gene flow · Genetic distance · Isolation by distance · Isolation by resistance · Landscape resistance · Snow leopard · Principal component analysis  
  Abstract (up) Context: The accurate estimation of landscape resistance to movement is important for ecological understanding and conservation applications. Rigorous estimation of resistance requires validation and optimization. One approach uses genetic data for the optimization or validation of resistance models. Objectives We used a genetic dataset of snow leopards from China to evaluate how landscape genetics resistance models varied across genetic distances and spatial scales of analysis. We evaluated whether landscape genetics models were superior to models of resistance derived from habitat suitability or isolation-by-distance.

Methods: We regressed genetically optimized, habitat-based, and isolation-by-distance hypotheses against genetic distances using mixed effect models. We explored all subset combinations of genetically optimized variables to find the most supported resistance scenario for each genetic distance.

Results: Genetically optimized models always out-performed habitat-based and isolation-by-distance hypotheses. The choice of genetic distances influenced the apparent influence of variables, their spatial scales and their functional response shapes, producing divergent resistance scenarios. Gene flow in snow leopards was largely facilitated by areas of intermediate ruggedness at intermediate elevations corresponding to small-to-large valleys within and between the mountain ranges.

Conclusions: This study highlights that landscape genetics models provide superior estimation of functional dispersal than habitat surrogates and suggests that optimization of genetic distance should be included as an optimization routine in landscape genetics, along with variables, scales, effect size and functional response shape. Furthermore, our study provides new insights on the ecological conditions that promote gene flow in snow leopards, which expands ecological knowledge, and we hope will improve conservation planning.

  Keywords Uzbekistan; Red Data book; category of threat; number; distribution; threats; snow leopard.; 6650; Russian  
  Abstract (up) Critically Endangered l (CR C2a(i); D), locally distributed western subspecies of Central Asian species. It occurs in Western Tien Shan and Western Pamir Alay. It inhabits middle and high belts of the mountains. It prefers watersheds and rocky talus slopes. It never was numerous; last decades the numbers have been decreasing. In 1980's-1990's in Hissar nature reserve 5-11 individuals were counted, in 1970's-1980's in Chatkal nature reserve the 1-3 specimens were observed. Perhaps, total number is 20-30 individuals. The threats are development of high mountain pastures, decreasing of prey numbers, human persecution and poaching. Included in the IUCN Red List [EN] and in Appendix I of CITES.

  Abstract (up) Decline of wild prey populations in the Himalayan region, largely due to competition with livestock, has been identified as one of the main threats to the snow leopard Uncia uncia. Studies show that bharal Pseudois nayaur diet is dominated by graminoids during summer, but the proportion of graminoids declines in winter. We explore the causes for the decline of graminoids from bharal winter diet and resulting implications for bharal conservation. We test the predictions generated by two alternative hypotheses, (H1) low graminoid availability caused by livestock grazing during winter causes bharal to include browse in their diet, and, (H2) bharal include browse, with relatively higher nutrition, to compensate for the poor quality of graminoids during winter. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. Graminoid quality in winter was relatively lower than that of browse, but the difference was not statistically significant. Bharal diet was dominated by graminoids in areas with highest graminoid availability. Graminoid contribution to bharal diet declined monotonically with a decline in graminoid availability. Bharal young to female ratio was three times higher in areas with high graminoid availability than areas with low graminoid availability. No starvation-related adult mortalities were observed in any of the areas. Composition of bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Since livestock grazing reduces graminoid availability, creation of livestock free areas is necessary for conservation of grazing species such as the bharal and its predators such as the endangered snow leopard in the Trans-Himalaya.

  Title What Are Snow Leopards Really Eating? Identifying Bias in Food-Habit Studies Type Journal Article
  Year 2016 Publication Wildlife Society Bulletin Abbreviated Journal  
  Volume Issue Pages 1-8  
  Keywords diet, DNA genotyping, feces, Panthera uncia, scat, snow leopard. Lack of  
  Abstract (up) Declining prey populations are widely recognized as a primary threat to snow leopard (Panthera

uncia) populations throughout their range. Effective snow leopard conservation will depend upon reliable

knowledge of food habits. Unfortunately, past food-habit studies may be biased by inclusion of nontarget

species in fecal analysis, potentially misinforming managers about snow leopard prey requirements.

Differentiation between snow leopard and sympatric carnivore scat is now cost-effective and reliable using

genetics. We used fecal mitochondrial DNA sequencing to identify scat depositors and assessment bias in

snow leopard food-habit studies. We compared presumed, via field identification, and genetically confirmed

snow leopard scats collected during 2005 and 2012 from 4 sites in Central Asia, using standard forensic

microscopy to identify prey species. Field identification success varied across study sites, ranging from 21% to

64% genetically confirmed snow leopard scats. Our results confirm the importance of large ungulate prey for

snow leopards. Studies that fail to account for potentially commonplace misidentification of snow leopard

scat may mistakenly include a large percentage of scats originating from other carnivores and report

inaccurate dietary assessments. Relying on field identification of scats led to overestimation of percent

occurrence, biomass, and number of small mammals consumed, but underestimated values of these measures for large ungulates in snow leopard diet. This clarification suggests that the conservation value of secondary prey, such as marmots (Marmota spp.) and other small mammals, may be overstated in the literature; stable snow leopard populations are perhaps more reliant upon large ungulate prey than previously understood.
