  Title (up) Preliminary results of a long-term study of snow leopards in South Gobi, Mongolia Type Journal Article
  Year 2010 Publication Cat News Abbreviated Journal  
  Volume Autumn Issue 53 Pages 15-19  
  Keywords snow leopard, Mongolia, monitor, population, Panthera, Snow Leopard Trust, Snow Leopard Conservation Fund, South Gobi, ecology, radio collar, GPS-satellite collar, home range, camera trapping, fecal genetics, occupancy modeling  
  Abstract Snow leopards Panthera uncia are under threat across their range and require urgent conservation actions based on sound science. However, their remote habitat and cryptic nature make them inherently difficult to study and past attempts have provided insufficient information upon which to base effective conservation. Further, there has been no statistically-reliable and cost-effective method available to monitor snow leopard populations, focus conservation effort on key populations, or assess conservation impacts. To address these multiple information needs, Panthera, Snow Leopard Trust, and Snow Leopard Conservation Fund, launched an ambitious long-term study in Mongolia’s South Gobi province in 2008. To date, 10 snow leo-pards have been fitted with GPS-satellite collars to provide information on basic snow leopard ecology. Using 2,443 locations we calculated MCP home ranges of 150 – 938 km2, with substantial overlap between individuals. Exploratory movements outside typical snow leopard habitat have been observed. Trials of camera trapping, fecal genetics, and occupancy modeling, have been completed. Each method ex-hibits promise, and limitations, as potential monitoring tools for this elusive species.

  Title (up) Seasonal variation in daily activity patterns of snow leopards and their prey Type Journal Article
  Year 2022 Publication Nature Portfolio Abbreviated Journal  
  Volume 12 Issue 21681 Pages 1-11  
  Keywords  
  Abstract The daily and seasonal activity patterns of snow leopards (Panthera uncia) are poorly understood, limiting our ecological understanding and hampering our ability to mitigate threats such as climate change and retaliatory killing in response to livestock predation. We fitted GPS-collars with activity loggers to snow leopards, Siberian ibex (Capra sibirica: their main prey), and domestic goats (Capra hircus: common livestock prey) in Mongolia between 2009 and 2020. Snow leopards were facultatively nocturnal with season-specific crepuscular activity peaks: seasonal activity shifted towards night- sunrise during summer, and day-sunset in winter. Snow leopard activity was in contrast to their prey, which were consistently diurnal. We interpret these results in relation to: (1) darkness as concealment for snow leopards when stalking in an open landscape (nocturnal activity), (2) low-intermediate light preferred for predatory ambush in steep rocky terrain (dawn and dusk activity), and (3) seasonal activity adjustments to facilitate thermoregulation in an extreme environment. These patterns suggest that to minimise human-wildlife conflict, livestock should be corralled at night and dawn in summer, and dusk in winter. It is likely that climate change will intensify seasonal effects on the snow leopard’s daily temporal niche for thermoregulation in the future.

  Title (up) Sex specific seasonal variation in puma and snow leopard home range utilization Type Journal Article
  Year 2018 Publication Ecosphere Abbreviated Journal  
  Volume 9 Issue 8 Pages 1-14  
  Keywords Cougar, female choice, LoCoH, mating tactics, Panthera Uncia, Puma concolor, spacing pattern, territoriality  
  Abstract Territory size is often larger for males than for females in species without biparental care. For large solitary carnivores, this is explained by males encompassing a set of female territories to monopolize their reproduction during mating (area maximization). However, males are expected to behave more like females outside of breeding, with their area utilization being dependent on the range required to secure food resources (area minimization). To examine how male and female solitary carnivores adjust their spatial organization during the year as key resources (mates and prey) change, we radio&#8208;collared 17 pumas (Puma concolor; nine males and eight females) and 14 snow leopards (Panthera uncia; seven males and seven females) and estimated home range size and overlap on two temporal scales (annual vs. monthly). Contrary to expectation, we found no evidence that males monopolized females (the mean territory overlap between females and the focal male during the mating season was 0.28 and 0.64 in pumas and snow leopards, respectively). Although male&#65533;male overlap of annual home ranges was comparatively high (snow leopards [0.21] vs. pumas [0.11]), monthly home range overlaps were small (snow leopards [0.02] vs. pumas [0.08]) suggesting strong territoriality. In pumas, both males and females reduced their monthly home ranges in winter, and at the same time, prey distribution was clumped and mating activity increased. In snow leopards, females showed little variation in seasonal home range size, following the seasonal stability in their primary prey. However, male snow leopards reduced their monthly home range utilization in the mating season. In line with other studies, our results suggest that female seasonal home range variation is largely explained by changes in food resource distribution. However, contrary to expectations, male territories did not generally encompass those of females, and males reduced their home ranges during mating. Our results show that male and female territorial boundaries tend to intersect in these species, and hint at the operation of female choice and male mate guarding within these mating systems.

  Title (up) Snow leopard predation in a livestock dominated landscape in Mongolia Type Journal Article
  Year 2015 Publication Biological Conservation Abbreviated Journal  
  Volume 184 Issue Pages 251-258  
  Keywords Gobi desert, GPS collar, Kill rate, Panthera uncial, Prey choice, Wildlife conflict  
  Abstract Livestock predation is an important cause of endangerment of the snow leopard (Panthera uncia) across

its range. Yet, detailed information on individual and spatio-temporal variation in predation patterns of

snow leopards and their kill rates of livestock and wild ungulates are lacking.

We collared 19 snow leopards in the Tost Mountains, Mongolia, and searched clusters of GPS positions

to identify prey remains and estimate kill rate and prey choice.

Snow leopards killed, on average, one ungulate every 8 days, which included more wild prey (73%) than

livestock (27%), despite livestock abundance being at least one order of magnitude higher. Predation on

herded livestock occurred mainly on stragglers and in rugged areas where animals are out of sight of herders.

The two wild ungulates, ibex (Capra ibex) and argali (Ovis ammon), were killed in proportion to their

relative abundance. Predation patterns changed with spatial (wild ungulates) and seasonal (livestock)

changes in prey abundance. Adult male snow leopards killed larger prey and 2–6 times more livestock

compared to females and young males. Kill rates were considerably higher than previous scat-based estimates, and kill rates of females were higher than kill rates of males. We suggest that (i) snow leopards

prey largely on wild ungulates and kill livestock opportunistically, (ii) retaliatory killing by livestock herders

is likely to cause greater mortality of adult male snow leopards compared to females and young

males, and (iii) total off-take of prey by a snow leopard population is likely to be much higher than previous

estimates suggest.

  Title (up) The timing of breeding and independence for snow leopard females and their cubs. Type Journal Article
  Year 2020 Publication Mammalian Biology Abbreviated Journal  
  Volume Issue Pages  
  Keywords Age of independence; Life-history trade-offs; Panthera uncia; Parental care; Pre-dispersal behavior; Separation; Subadult  
  Abstract Significant knowledge gaps persist on snow leopard demography

and reproductive behavior. From a GPS-collared population in Mongolia,

we estimated the timing of mating, parturition and independence. Based

on three mother–cub pairs, we describe the separation phase of the cub

from its mother as it gains independence. Snow leopards mated from

January–March and gave birth from April–June. Cubs remained with their

mother until their second winter (20–22 months of age) when cubs started

showing movements away from their mother for days at a time. This

initiation of independence appeared to coincide with their mother mating

with the territorial male. Two female cubs remained in their mothers’

territory for several months after initial separation, whereas the male

cub quickly dispersed. By comparing the relationship between body size

and age of independence across 11 solitary, medium-to-large felid

species, it was clear that snow leopards have a delayed timing of

separation compared to other species. We suggest this may be related to

their mating behavior and the difficulty of the habitat and prey capture

for juvenile snow leopards. Our results, while limited, provide

empirical estimates for understanding snow leopard ecology and for

parameterizing population models.

  Title (up) Variation in plant composition along a gradient of increasing distance from wells in a mountain steppe in southern Mongolia Type Journal Article
  Year 2023 Publication Snow Leopard Reports Abbreviated Journal  
  Volume Issue Pages 10-16  
  Keywords desert steppe, livestock grazing, plant composition, South Gobi  
  Abstract Habitat degradation and heavy grazing by livestock are common conservation challenges across the steppes of Mongolia and Central Asia. Livestock grazing patterns are generally not uniform and are typically greater near campsites and watering holes. In this study, we examined how plant composition in a mountain steppe in southern Mongolia varied along a gradient of increasing distance from wells. We found that the cover and average height of Ephedra prezewalskii increased with increasing distance from the wells whereas soil chemistry and the other variables of plant composition that we examined were similar along the gradient of increasing distance from the wells. These results suggest relatively limited impact of livestock grazing on plant composition in our study. However, our study was limited in space and time and further studies are needed to understand the impact of livestock grazing in this mountain steppe in southern Mongolia.

  Title (up) Vigorous Dynamics Underlie a Stable Population of the Endangered Snow Leopard Panthera uncia in Tost Mountains, South Gobi, Mongolia Type Journal Article
  Year 2014 Publication Plos One Abbreviated Journal  
  Volume 9 Issue 7 Pages  
  Keywords  
  Abstract Population monitoring programmes and estimation of vital rates are key to understanding the mechanisms of population growth, decline or stability, and are important for effective conservation action. We report, for the first time, the population trends and vital rates of the endangered snow leopard based on camera trapping over four years in the Tost Mountains, South Gobi, Mongolia. We used robust design multi-season mark-recapture analysis to estimate the trends in abundance, sex ratio, survival probability and the probability of temporary emigration and immigration for adult and young snow leopards. The snow leopard population remained constant over most of the study period, with no apparent growth (l = 1.08+20.25). Comparison of model results with the ‘‘known population’’ of radio-collared snow leopards suggested

high accuracy in our estimates. Although seemingly stable, vigorous underlying dynamics were evident in this population, with the adult sex ratio shifting from being male-biased to female-biased (1.67 to 0.38 males per female) during the study. Adult survival probability was 0.82 (SE+20.08) and that of young was 0.83 (SE+20.15) and 0.77 (SE +20.2) respectively, before and after the age of 2 years. Young snow leopards showed a high probability of temporary emigration and immigration (0.6, SE +20.19 and 0.68, SE +20.32 before and after the age of 2 years) though not the adults (0.02 SE+20.07). While the current female-bias in the population and the number of cubs born each year seemingly render the study population safe, the vigorous dynamics suggests that the situation can change quickly. The reduction in the proportion of

male snow leopards may be indicative of continuing anthropogenic pressures. Our work reiterates the importance of monitoring both the abundance and population dynamics of species for effective conservation.

  Title (up) Wild versus domestic prey: Variation in the kill-site behavior of two large felids Type Journal Article
  Year 2023 Publication Global Ecology and Conservation Abbreviated Journal  
  Volume 47 Issue e026750 Pages 1-13  
  Keywords Eurasian lynx, Handling time, Landscape, Livestock, Predation, Snow leopard  
  Abstract Livestock depredation is an important source of conflict for many terrestrial large carnivore

species. Understanding the foraging behavior of large carnivores on domestic prey is therefore

important for both mitigating conflict and conserving threatened carnivore populations. Handling

time is an important, albeit often overlooked, component of predatory behavior, as it directly

influences access to food biomass, which can affect predator foraging efficiency and subsequent

kill rates. We used long-term data on snow leopards (Panthera uncia) in Mongolia (Asia) and

Eurasian lynx (Lynx lynx) in Norway (Europe) to examine how large carnivore foraging patterns

varied between domestic and wild prey, and how the different landscape characteristics affected

those patterns. Our results suggest handling time was generally shorter for domestic compared to

wild prey. For snow leopards, rugged terrain was linked to increased handling time for larger

prey. For lynx, handling time increased with terrain ruggedness for domestic, but not wild, prey,

and was greater in closed compared to open habitats. There were also other differences in snow

leopard and lynx foraging behavior, e.g., snow leopards also stayed longer at, and remained closer

to, their kill sites than lynx. Shorter handling time suggests that felids may have utilized domestic

prey less effectively than wild prey, i.e., they spent less time consuming their prey. This could a)

result in an energetic or fitness cost related to decreased felid foraging efficiency caused by the

risk of anthropogenic disturbance, or b) exacerbate conflict if reduced handling time associated

with easy prey results in increased livestock depredation.
