Abstract |
Conserving large carnivores in an increasingly crowded planet raises difficult challenges. A recurring debate is whether large carnivores can be conserved in human used landscapes (land sharing) or whether they require specially designated areas (land sparing). Here we show that 40% of the 170 protected areas in the global range of the snow leopard (Panthera uncia) are smaller than the home range of a single adult male and only 4– 13% are large enough for a 90% probability of containing 15 or more adult females. We used data from 16 snow leopards equipped with GPS collars in the Tost Mountains of South Gobi, Mongolia, to calculate home range size and overlap using three different estimators: minimum convex polygons (MCP), kernel utility distributions (Kernel), and local convex hulls (LoCoH). Local convex hull home ranges were smaller and included lower proportions of unused habitats compared to home ranges based on minimum convex polygons and Kernels. Intra-sexual home range overlapwas low, especially for adult males, suggesting that snowleopards are territorial. Mean home range size based on the LoCoH estimates was 207 km2 ± 63 SD for adult males and 124 km2 ± 41 SD for adult females. Our estimates were 6–44 times larger than earlier estimates based on VHF technology when comparing similar estimators, i.e. MCP. Our study illustrates that protected areas alone will not be able to conserve predatorswith large home ranges and conservationists and managers should not restrict their efforts to land sparing. |

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. |

Abstract |
We describe an automated system for Monitoring multiple very high frequency (VHF) transmitters, which are commonly employed in wildlife studies. The system consists of a microprocessor-controlled radio-frequency monitor equipped with advanced signal-processing capabilities that communicates with, and release snow leopard (Panthera uncia) study in Mongolia, where checking trap-site transmitters manually entailed climbing a hill with telemetry equipment several times each day and night. Here, it monitors the trap site transmitters and actively produces an alarm when any of the traps have been triggered, or if the system has lost contact with any trap-transmitter. The automated system allowed us to constantly monitor transmitters from a research camp, and alerted us each time a trap was triggered. The sys ten has been field-tested for 83 days from mid-September 2010 to mid- December 2010 in the Tost mountain range on the edge of Mongolia's Gobi desert. During this time, the system performed reliably, responding correctly to 45 manually generated alarms and 9 animal captures. The system considerably sorters the time the captured animals spend in traps, and also mitigates the need for manual trap-site transmitter monitoring, greatly reducing risk to the animal and the human effort involved. |

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. |

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.

Abstract |
Human-wildlife conflict (HWC) is a serious problem in many parts of the world, and Bhutan�s Wangchuck Centennial
National Park (WCNP) is no exception. Located in the remote alpine areas of the eastern Himalaya, wildlife species
such as snow leopard (SL) and Tibetan wolf (TW) are reported to kill livestock in many parts of the Park. Such
depredation is believed to have affected the livelihoods of high-altitude herding communities, resulting in conflicts
between them. This study provides analysis on the extent of livestock depredation by wildlife predators such as SL
and TW and examines its implications for the livelihoods of herding communities of Choekhortoe and Dhur regions
of WCNP. Using semi-structured questionnaires, all herders (n = 38) in the study area were interviewed. The questions
pertained to livestock population, frequency of depredation and income lost due to depredation in the last five years
from 2012 to 2016. This study recorded 2,815 livestock heads in the study area, with an average herd size of 74.1 stock.
The average herd size holding showed a decreasing trend over the years, and one of the reasons cited by the herders
is depredation by SL and TW and other predators. This loss equated to an average annual financial loss equivalent to
10.2% (US$837) of their total per capita cash income. Such losses have resulted in negative impacts on herders�
livelihood; e.g. six herders (2012-2016) even stopped rearing livestock and resorted to an alternate source of cash
income. The livestock intensification programmes, including pasture improvement through allowing controlled
burning, and financial compensation, may be some potential short-term solutions to reduce conflict between herders
and predators. Issuing permits for cordyceps (Ophiocordyceps sinensis) collection only to the herders and instilling the
sense of stewardship to highland herders may be one of the long-term solutions. |

Abstract |
Pastoralism and predation are two major concomitantly known facts and matters of concern for conservation biologists worldwide. Pastoralist-predator conflict constitutes a major social-ecological concern in the Pamir mountain range encompassing Afghanistan, Pakistan, and Tajikistan, and affects community attitudes and tolerance toward carnivores. Very few studies have been conducted to understand the dynamics of livestock predation by large carnivores like snow leopards (Panthera uncia) and wolves (Canis
lupus), owing to the region�s remoteness and inaccessibility. This study attempts to assess the intensity of livestock predation (and resulting perceptions) by snow leopards and wolves across the Afghani, Pakistani, and Tajik Pamir range during the period January 2008�June 2012. The study found that livestock mortality due to disease is the most serious threat to livestock (an average 3.5 animal heads per household per year) and ultimately to the rural economy (an average of US$352 per household per year) as compared to
predation (1.78 animal heads per household per year, US$191) in the three study sites. Overall, 1419 (315 per year) heads of livestock were reportedly killed by snow leopards (47%) and wolves (53%) in the study sites. People with comparatively smaller landholdings and limited earning options, other than livestock rearing, expressed negative attitudes toward both wolves and snow leopards and vice versa. Education was found to be an effective solution to dilute people�s hatred for predators. Low public tolerance of the wolf and
snow leopard in general explained the magnitude of the threat facing predators in the Pamirs. This will likely continue unless tangible and informed conservation measures like disease control and predation compensation programs are taken among others. |

Book Title: Rangeland Stewardship in Central Asia: Balancing Improved Livelihoods, Biodiversity Conservation and Land Protection, 2012. Edited by Victor Squires. Published Springer Science+Business Media. 458 p. 91 illus., 61 in color.
Addressing human–wildlife conflict is an important requisite to managing
rangelands for livestock and wildlife. Despite high altitudes, aridity, and relatively
low primary productivity, the rangelands of Central Asia support a rich and diverse
biodiversity—including the endangered snow leopard that many herders perceive
as a predator to be eliminated. Conserving this and other wildlife species requires
carefully crafted interventions aimed at curbing depredation losses and/or reducing
competition for forage, along with offering locally sustainable, environmentally
friendly income-generating activities for supplementing pastoral household livelihoods.
This is best achieved through a combination of incentives designed to foster
sound rangeland and wildlife stewardship, along penalties or disincentives targeting
herders who violate mutually agreed rules and regulations (including grazing norms
and wildlife disturbance or poaching).
When working toward the harmonious coexistence of people and wildlife,
conservationists and rangeland practitioners need to seek the cooperation and
build goodwill among herders and other stakeholders, including local government
and private industry (especially the livestock production, mining, and tourism
sectors). |
