Title | Common and snow leopards share prey, but not habitats: competition avoidance by large predators | Type | Journal Article | ||
Year | 2013 | Publication | Journal of Zoology | Abbreviated Journal | |

Keywords | coexistence; resource partitioning; food habits; Panthera uncia; Panthera pardus. | ||||
Abstract | Resource exploitation and behavioural interference underlie competition among carnivores. Competition is reduced by specializing on different prey and/or spatiotemporal separation, usually leading to different food habits. We predicted that two closely related species of large cats, the endangered snow leopard and the near-threatened common leopard, living in sympatry, would coexist through habitat separation and exploitation of different prey species. In central Himalaya, we assessed (2006–2010) habitat and diet overlap between these carnivores. The snow leopard used grassland and shrubland, whereas the common leopard selected forest. Contrary to our prediction, snow leopard and common leopard preyed upon similar wild (Himalayan tahr, musk deer) and domestic species (Bos spp., dogs). Dietary overlap between snow leopard and common leopard was 69% (yearly), 76% (colder months) and 60% (warmer months). Thus, habitat separation should be the result of other factors, most likely avoidance of interspecific aggression. Habitat separation may not always lead to the use of different prey. Avoidance of interspecific aggression, rather than exploitation of different resources, could allow the coexistence of potentially competing large predators. |

Title | Food habits of two leopard species, competition, climate change and upper treeline: a way to the decrease of an endangered species? | Type | Journal Article | ||
Year | 2013 | Publication | Ethology Ecology & Evolution | Abbreviated Journal | |
Volume | 25 | Issue | 4 | Pages | 305-318 |
Keywords | carnivore evolution, coexistence, sympatric species, diet, Panthera uncia, Panthera pardus. | ||||
Abstract | For carnivore species, spatial avoidance is one of the evolutionary solutions to coexist in an area, especially if food habits overlap and body sizes tend to coincide. We reviewed the diets of two large cats of similar sizes, the endangered snow leopard (Panthera uncia, 16 studies) and the near-threatened common leopard (Panthera par- dus, 11 studies), in Asia. These cats share ca 10,000 km2 of their mountainous range, although snow leopards tend to occur at a significantly higher altitude than common leopards, the former being a cold-adapted species of open habitats, whereas the latter is an ecologically flexible one, with a preference for woodland. The spectrum of prey of common leopards was 2.5 times greater than that of snow leopards, with wild prey being the staple for both species. Livestock rarely contributed much to the diet. When the breadth of trophic niches was compared, overlap ranged from 0.83 (weight categories) to one (main food categories). As these leopard species have approximately the same size and comparable food habits, one can predict that competition will arise when they live in sympatry. On mountains, climate change has been elevating the upper forest limit, where both leopard species occur. This means a habitat increase for common leopards and a substantial habitat reduction for snow leopards, whose range is going to be squeezed between the forest and the barren rocky altitudes, with medium- to long-term undesirable effects on the conservation of this endangered cat |

Title | Using time-to-event analysis to complement hierarchical methods when assessing determinants of photographic detectability during camera trapping | Type | Journal Article | ||

Abstract | 1. Camera trapping, paired with analytical methods for estimating occupancy, abundance and other ecological parameters, can yield information with direct consequences for wildlife management and conservation. Although ecological information is the primary target of most camera trap studies, detectability influences every aspect from design to interpretation. 2. Concepts and methods of time-toevent analysis are directly applicable to camera trapping, yet this statistical field has thus far been ignored as a way to analyze photographic capture data. to illustrate the use to time-to-event statistics and to better understand how photographic evidence accumulates, we explored patterns in tow related measure of detectability: Detection probability and time to detection. We analyzed camera trap data for three sympatric carnivores ( snow Leopard, red fox and stone marten) in the mountains of northern Pakistan and tested predictions about patterns in detectability across species, sites and time. 3. We found species-specific differences in the magnitude of detectability and the factors influencing it, reinforcing the need to consider determinants of detectability in study design and to account for them during analysis. Photographic detectability of snow leopard was noticeably lower than that of red fox, but comparable to detectability of stone marten. Site-specific attributes such as the presence of carnivore sign ( snow Leopard), terrain ( snow leopard and red fox) and application for lures ( red fox) influenced detectability. For the most part, detection probability was constant over time. 4. Species- specific differences in factors determining detectability make camera trap studies targeting multiple species particularly vulnerable to misinterpretation if the hierarchical origin of the data is ignored. Investigators should consider not only the magnitude of detectability, but also the shape of the curve describing the cumulative process of photographic detection, as this has consequences for both determining survey effort and the election of analytical models. Weighted time-to -event analysis can complement occupancy analysis and other hierarchal methods by providing additional tools for exploring camera trap data and testing hypotheses regarding the temporal aspect of photographic evidence accumulation. |

Title | Trophy Hunting of Cites-Listed Species in Central Asia | Type | Report | ||
Year | 2013 | Publication | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | Executive Summary: The report is part of a project aiming to strengthen capacities to implement CITES, especially in Central Asia and to satisfy the CITES‐related requirements of trading partners, to prevent overexploitation and to ensure legal international trade in wild fauna and flora does not exceed sustainable levels. The objective is to enhance the policies and regulations concerning trophy hunting in selected range States of the Argali Ovis ammon: Kazakhstan, Kyrgyzstan, the Russian Federation, Tajikistan and Uzbekistan and to provide a framework for the establishment of sustainable hunting programmes that support conservation. This report is focused on the relevance of trophy hunting for conservation and associated local livelihoods. Sustainable use of biological diversity is an integral part of the Convention on Biodiversity (1992) and is seen as a valuable tool in conserving biological diversity. The Addis Ababa Principles and Guidelines (AAPG) set out the basis for sustainable use of natural resources. The IUCN SSC1 Guiding Principles on Trophy Hunting as a Tool for Creating Conservation Incentives, and the European Charter on Hunting and Biodiversity provide further guidance on the sustainability of trophy hunting, including on highly threatened species. The International Council for Game and Wildlife Conservation (CIC) together with the Food and Agriculture Organization of the United Nations (FAO) has also developed Best Practice Guidelines for trophy hunting. All five project countries are Parties to CITES, except Tajikistan, which has begun the accession process. Argali are the focus of the trophy hunting in the region and they represent the most expensive trophy in the five project countries. Other CITES‐listed hunting species are Brown Bear Ursus arctos, Wolf Canis lupus, Musk Deer Moschus moschiferus, Eurasian Lynx Lynx lynx (all mainly in Russia) and Houbara Bustard Chlamydotis undulata. Markhor Capra falconeri and Urial Ovis orientalis have also been hunted at times but are not the object of regular trophy hunting programmes at present. Other widely hunted species are not listed in the CITES Appendices. A recent analysis by TRAFFIC of the CITES trade database showed that 10 245 hunting trophy items from species listed in the CITES Appendices were exported from the project countries between 2000 and 2010. Almost all trophy items consisted of Argali, Brown Bear and Wolf. Most were exported from Russia (9473 trophies), with smaller numbers from Tajikistan (705), Kyrgyzstan (668), and Kazakhstan (126), and 13 from Uzbekistan. In the region, wildlife is generally the property of the State, which awards rights to use it to individuals or other entities. National legislation covering hunting and wildlife protection may refer to sustainable use but this is undefined. The legal rights of local communities are also not generally specified. FAO and CIC produced a review of national legislation that set out in detail the basic principles of sustainable wildlife management laws (2008). One of the main findings was that legislative frameworks in the region frequently consisted of different legal instruments that were not always harmonized and sometimes overlapped. In some cases, there was also a lack of institutional clarity, with overlapping jurisdictions among different agencies. Poaching for meat and trophies or commercial products is a significant factor across the whole region, negatively affecting all the main hunting species, as well as protected species. Wild populations have been reduced, sometimes drastically so. Poaching of Argali and other mountain ungulates may be carried out by military or border personnel and is not restricted to areas outside formal nature reserves: indeed, law enforcement and protected area staff are sometimes complicit in illegal hunting, driven in part by the very low salaries. There are numerous recent examples of poaching and illegal trade in trophies of CITES‐listed species. The actual level of illegal off‐take is unknown. Known cases may represent a very small fraction of the real total. The wildlife conservation sector is under‐resourced across the region with a lack of funding, trained personnel, transport and other equipment severely limiting the effectiveness of anti‐poaching efforts. Memoranda of Understanding under the Convention on Migratory Species (CMS MoUs) and their associated action plans for Saiga Saiga tatarica and Bukhara Deer Cervus elaphus bactrianus have proven to be effective instruments in facilitating species recovery. A CMS Single Species Action Plan for Argali is in preparation (Roettger & Singh, in prep) and will provide a framework for conservation. Trophy hunting in the region is predominantly organized on a commercial basis. Community‐based hunting initiatives in the region are in their infancy and face some legal and institutional obstacles. There are however promising developments: for example, five community‐based NGOs in Tajikistan are managing wildlife in legally assigned areas and three of them have hosted hunting clients (on non‐CITES species). Well‐developed community‐based trophy hunting programmes operate in Pakistan, targeted at Markhor Capra falconeri which is listed in CITES Appendix I, and in Namibia, which is widely seen as a leader in such programmes, and while the specific conditions and sociopolitical background of both differ in several ways from those in the region, they nonetheless provide instructive guidance on the principles of successful community conservancy organization. There is an extensive literature on trophy hunting, its potential to contribute to conservation of biodiversity and local livelihoods, and the potential negative effects of selective harvesting on species. The consensus view seems to be that selective harvest of trophy‐age males does not impact negatively in the short term, if only a low proportion of the available trophy‐age individuals are harvested, but uncontrolled harvest can lead to a decline in horn size and thus trophy quality, as well as have negative demographic effects. Trophy hunting programmes raise substantial revenues in some African countries, and in the best cases significant sums are received at community or conservancy level. However, this is not universally the case and inequitable benefit sharing remains a major challenge to be overcome. Good governance is an essential requirement when developing hunting and other forms of community based management initiative. A possible decline in size of Argali trophies in Kyrgyzstan has been reported and determining whether this is actually the case, and the causes, is a priority. Standardized monitoring, involvement of independent experts, transparency in quota setting and allocation of licences are all seen as prerequisites of well‐managed and sustainable hunting operations. Allocation of long‐term leases for concessions is needed to motivate managers to invest in anti‐poaching and other conservation measures and remove the temptation for short‐term profit that threatens the sustainability of the resource. Developing all forms of Community‐based Natural Resource Management (CBNRM) – trophy hunting and tourism – is also recommended. As the concept is still new to many parts of the region, and the legal‐political background is not always sympathetic, building on examples of existing community conservancies (in Tajikistan) or where there is an administrative basis for local management of resources (Kyrgyzstan), is likely to be effective. Ensuring that communities and conservancies are legally empowered to manage and utilise wildlife and to receive revenues for such use is a basic requirement. Recommendations on good practice are set out in several publications and salient points relevant to the region are highlighted. |

Title | Applications and techniques for non-invasive faecal genetics research in felid conservation | Type | Journal Article | ||
Year | 2013 | Publication | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | Conservation . Elusive species . Faecal DNA . Felidae . Non-invasive genetics | ||||
Abstract | Non-invasive genetic techniques utilising DNA extracted from faeces hold great promise for felid conservation research. These methods can be used to establish species distributions, model habitat requirements, analyse diet, estimate abundance and population density, and form the basis for population, landscape and conservation genetic analyses. Due to the elusive nature of most felid species, non-invasive genetic methods have the potential to provide valuable data that cannot be obtained with traditional observational or capture techniques. Thus, these methods are particularly valuable for research and conservation of endangered felid species. Here, we review recent studies that use non-invasive faecal genetic techniques to survey or study wild felids; provide an overview of field, laboratory and analysis techniques; and offer suggestions on how future non-invasive genetic studies can be expanded or improved to more effectively support conservation. |

Title | Participatory Rural Appraisal and Compensation Intervention: Challenges and Protocols While Managing Large Carnivore–Human Conflict | Type | Journal Article | ||
Year | 2014 | Publication | Human Dimensions of Wildlife: An International Journal | Abbreviated Journal | |
Volume | 19 | Issue | Pages | 62-71 | |
Keywords | PRA, large carnivores–human conflict, compensation, livestock depredation, data collection protocols | ||||
Abstract | When large carnivores cause socioeconomic losses in a community, conflict increases, retaliatory killing of the carnivore can occur, and conservation efforts are undermined. We focused on Participatory Rural Appraisal (PRA) and economic compensation schemes as approaches for managing conflict. PRA is a tool for collecting data on the large carnivore–human conflict and economic compensation schemes for those affected negatively by carnivore presence. We reviewed published papers and reports on large carnivore–human conflicts, PRA, and compensation schemes. This article details insights into common pitfalls, key lessons learned, possible solutions including new approaches for compensation and protocols to be followed while managing large carnivore–human conflict. We hope to contribute to a meaningful dialogue between locals, managers, and researchers and help in effective implementation of conservation programs to mitigate large carnivore–human conflict around the protected areas. |

Title | Prey Preferences of the Snow Leopard (Panthera uncia): Regional Diet Specificity Holds Global Significance for Conservation | Type | Journal Article | ||
Year | 2014 | Publication | Plos One | Abbreviated Journal | |
Volume | 9 | Issue | 2 | Pages | 1-11 |
Keywords | snow leopard, prey species, prey consumption | ||||
Abstract | The endangered snow leopard is a large felid that is distributed over 1.83 million km2 globally. Throughout its range it relies on a limited number of prey species in some of the most inhospitable landscapes on the planet where high rates of human persecution exist for both predator and prey. We reviewed 14 published and 11 unpublished studies pertaining to snow leopard diet throughout its range. We calculated prey consumption in terms of frequency of occurrence and biomass consumed based on 1696 analysed scats from throughout the snow leopard’s range. Prey biomass consumed was calculated based on the Ackerman’s linear correction factor. We identified four distinct physiographic and snow leopard prey type zones, using cluster analysis that had unique prey assemblages and had key prey characteristics which supported snow leopard occurrence there. Levin’s index showed the snow leopard had a specialized dietary niche breadth. The main prey of the snow leopard were Siberian ibex (Capra sibrica), blue sheep (Pseudois nayaur), Himalayan tahr (Hemitragus jemlahicus), argali (Ovis ammon) and marmots (Marmota spp). The significantly preferred prey species of snow leopard weighed 5565 kg, while the preferred prey weight range of snow leopard was 36–76 kg with a significant preference for Siberian ibex and blue sheep. Our meta-analysis identified critical dietary resources for snow leopards throughout their distribution and illustrates the importance of understanding regional variation in species ecology; particularly prey species that have global implications for conservation. |

Abstract | Consequences of predation may be particularly heavy on small populations of herbivores, especially if they are threatened with extinction. Over the 2006–2010 period, we documented the effects of the spontaneous return of the endangered snow leopard on the population of the vulnerable Himalayan tahr. The study area was an area of central Himalaya where this cat disappeared c. 40 years before, because of persecution by man. Snow leopards occurred mainly in areas close to the core area of tahr distribution. Tahr was the staple (56.3 %) of snow leopards. After the arrival of this cat, tahr decreased by more than 2/3 from 2003 to 2010 (mainly through predation on kids). Subsequently, the density of snow leopards decreased by 60%from2007 to 2010. The main prey of snow leopards in Asia (bharal, marmots) were absent in our study area, forcing snow leopards to specialize on tahr. The restoration of a complete prey spectrum should be favoured through reintroductions, to conserve large carnivores and to reduce exploitation of small populations of herbivores, especially if threatened. |
