Abstract |
To better understand the biology of snow leopard spermatozoa and to facilitate developing assisted reproduction, a series of studies was conducted to: 1) identify the component(s) of complex culture media responsible for the detrimental effect on sperm survival in vitro, 2) optimize medium for supporting sperm viability, and 3) evaluate sperm capacitation in vitro. Constituents of complex media were added systematically to phosphate-buffered saline (PBS) to isolate the factor(s) influencing snow leopard sperm motility in vitro. Sperm capacitation was also assessed following incubation in PBS with bovine serum albumin (BSA), fetal calf serum (FCS), or heparin. For maintaining sperm motility, there was no benefit (P ? 0.05) to supplementing PBS with low (5%) or high (20%) concentrations of snow leopard serum (SLS) versus FCS or BSA. Likewise, adding supplemental energy substrates (pyruvate, glucose, lactate, or glutamine) did not enhance or hinder (P ? 0.05) sperm motility. However, motility rapidly decreased (P < 0.05) with the addition of NaHCO3 to PBS or Ham's F10 nutrient mixture. Surprisingly, Ham's F10 with no buffering component or with both NaHCO3 and N-Z-hydroxyethylpiperazine-N'-2- ethanesulfonic acid (HEPES) maintained sperm motility at levels similar (P ? 0.05) to PBS. Although sperm motility in all treatments decreased with time, there was a strong inverse relationship (P < 0.01; r = 0.90) between motility and sample pH at 6 hours. Spermatozoa incubated in PBS containing FCS, BSA, or heparin did not undergo the acrosome reaction when exposed to calcium ionophore. In summary, alkaline pH has a profound detrimental effect on snow leopard sperm motility, and capacitation does not occur under conditions that normally promote this event in other felid species. These results clearly demonstrate a high degree of interspecific variation among felids in fundamental sperm function, and they provide evidence for the necessity of basic research when developing assisted reproduction in little-studied nondomestic species. |

Abstract |
Top carnivores play an important role in maintaining energy flow and functioning of the ecosystem,
and a clear understanding of their diets and foraging strategies is essential for
developing effective conservation strategies. In this paper, we compared diets and prey
selection of snow leopards and wolves based on analyses of genotyped scats (snow leopards
n = 182, wolves n = 57), collected within 26 sampling grid cells (5×5 km) that were distributed
across a vast landscape of ca 5000 km2 in the Central Himalayas, Nepal. Within the
grid cells, we sampled prey abundances using the double observer method. We found that
interspecific differences in diet composition and prey selection reflected their respective
habitat preferences, i.e. snow leopards significantly preferred cliff-dwelling wild ungulates
(mainly bharal, 57% of identified material in scat samples), whereas wolves preferred typically
plain-dwellers (Tibetan gazelle, kiang and argali, 31%). Livestock was consumed less
frequently than their proportional availability by both predators (snow leopard = 27%; wolf =
24%), but significant avoidance was only detected among snow leopards. Among livestock
species, snow leopards significantly preferred horses and goats, avoided yaks, and used
sheep as available. We identified factors influencing diet composition using Generalized Linear
Mixed Models. Wolves showed seasonal differences in the occurrence of small mammals/
birds, probably due to the winter hibernation of an important prey, marmots. For snow
leopard, occurrence of both wild ungulates and livestock in scats depended on sex and latitude.
Wild ungulates occurrence increased while livestock decreased from south to north,
probably due to a latitudinal gradient in prey availability. Livestock occurred more frequently
in scats from male snow leopards (males: 47%, females: 21%), and wild ungulates more frequently
in scats from females (males: 48%, females: 70%). The sexual difference agrees
with previous telemetry studies on snow leopards and other large carnivores, and may
reflect a high-risk high-gain strategy among males. |

Abstract |
Trans Himalayas experience extremes of cold and arid climatic conditions which account for their lower productivity. The wild animals occur in lower densities and need relatively large areas to maintain viable populations. Though these animals are fully adapted to these environmental conditions, increasing human pressure poses a great threat to their survival.
Trans Himalayas are intrinsically a fragile ecosystem and their overuse has pushed them close to ravage in many localities. Higher Himalayas are progressively threatened by the increasing developmental activities such as opening up by new roads and and increasing number of satellite townships.
This region has long remained unstudied by conservationists. The paucity of information on this region is very well recognised by the managers and conservationists in the country as well as the world over. For better management and conservation of wildlife in the region, it is of paramount importance to have atleast the basic information on the status, distribution of flora and fauna, and other environmental and socio-economic aspects. |

Abstract |
Translocations are an important tool for the conservation
of biodiversity, but although ecological feasibility
studies are frequently conducted prior to implementation,
social feasibility studies that consider how local communities
perceive such projects are less common. The translocation
of blue sheep Pseudois nayaur to Sagarmatha National
Park, Nepal, has been proposed, to reduce livestock depredation
by snow leopards Panthera uncia by providing an alternative
prey base in addition to the small population of
Himalayan thar Hemitragus jemlahicus. This study used
systematic sampling, a quantitative questionnaire and qualitative
interviews within the Park to provide data on the social
viability of the proposed translocation. Quantitative
analysis revealed moderate levels of support but qualitative
analysis suggested that there are significant concerns about
the proposal. In addition,multiple regression analysis found
that women and livestock owners were significantly less
supportive, although the model had low explanatory
power. Potential crop damage and competition for forage
were frequently cited as concerns, especially amongst
those with a high level of dependence on natural resources.
Given the mixed response to the proposed translocation of
blue sheep to the Everest region, alleviating the reservations
of local residents is likely to be key to any further consultation,
planning or implementation. |

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. |

Abstract |
Trophy hunting and mass tourism are the two major interventions designed to provide various socioeconomic and ecological benefits at the local and regional levels. However, these interventions have raised some serious concerns that need to be addressed. This study was conducted in Khunjerab National Park (KNP) with an aim to analyze comparatively the socioeconomic and ecological impacts of trophy hunting and mass tourism over the last three decades within the context of sustainability. Focus Group Discussions (FGDs) with key stakeholders and household interviews were conducted to collect data on trophy hunting and mass tourism, and on local attitudes towards these two interventions in and around KNP. The results revealed that 170 Ibex (Capra sibirica) and 12 Blue sheep (Pseudois nayaur) were hunted in the study area over the past three decades, and trophy hunting was not based on a sustainable harvest level. Trophy hunting on average generated USD 16,272 annual revenue, which was invested in community development. However, trophy hunting has greatly changed the attitudes of local residents towards wildlife: a positive attitude towards the wild ungulates and strongly negative attitude towards wild carnivores. In addition, trophy hunting has reduced the availability of ungulate prey species for Snow leopards (Panthera uncia), and consequently, Snow leopards have increased their predation on domestic livestock. This has, in turn, increased human–snow leopard conflict, as negative attitudes towards carnivores result in retaliatory killing of Snow leopards. Furthermore, according to ocial record data, the number of tourists to KNP has increased tremendously by 10,437.8%, from 1382 in 1999 to 145,633 in 2018. Mass tourism on average generated USD 33,904 annually and provided opportunities for locals to earn high incomes, but it caused damages to the environment and ecosystem in KNP through pollution generation and negative impacts on wildlife. Considering the limited benefits and significant problems created by trophy hunting and mass tourism, we suggest trophy hunting should be stopped and mass tourism should be shifted to ecotourism in and around KNP. Ecotourism could mitigate human–Snow leopard conflicts and help conserve the fragile ecosystem, while generating enough revenue incentives for the community to protect biodiversity and compensate for livestock depredation losses to Snow leopards. Our results may have implications for management of trophy hunting and mass tourism in other similar regions that deserve further investigation. |

Abstract |
Twenty-five years ago, the snow leopard Uncia uncia, an endangered large cat, was eliminated from what is now Sagarmatha National Park (SNP). Heavy hunting pressure depleted that area of most medium-large mammals, before it became a park. After three decades of protection, the cessation of hunting and the recovery of wild ungulate populations, snow leopards have recently returned (four individuals). We have documented the effects of the return of the snow leopard on the population of its main wild prey, the Himalayan tahr Hemitragus jemlahicus, a 'near-threatened' caprin. Signs of snow leopard presence were recorded and scats were collected along a fixed trail (130 km) to assess the presence and food habits of the snow leopard in the Park, from 2004 to 2006. Himalayan tahr, the staple of the diet, had a relative occurrence of 48% in summer and 37% in autumn, compared with the next most frequent prey, musk deer Moschus chrysogaster (summer: 20%; autumn: 15%) and cattle (summer: 15%; autumn: 27%). In early summer, the birth rate of tahr (young-to-female ratio: 0.8-0.9) was high. The decrease of this ratio to 0.1-0.2 in autumn implied that summer predation concentrated on young tahr, eventually altering the population by removing the kid cohort. Small populations of wild Caprinae, for example the Himalayan tahr population in SNP, are sensitive to stochastic predation events and may be led to almost local extinction. If predation on livestock keeps growing, together with the decrease of Himalayan tahr, retaliatory killing of snow leopards by local people may be expected, and the snow leopard could again be at risk of local extinction. Restoration of biodiversity through the return of a large predator has to be monitored carefully, especially in areas affected by humans, where the lack of important environmental components, for example key prey species, may make the return of a predator a challenging event. |
