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 | |
Volume | 291 | Issue | Pages | 127-135 | |
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 | Large carnivores and low diversity of optimal prey: a comparison of the diets of snow leopards Panthera uncia and wolves Canis lupus in Sarychat-Ertash Reserve in Kyrgyzstan | Type | Journal Article | ||
Year | 2013 | Publication | Oryx | Abbreviated Journal | |
Volume | Issue | Pages | 1-7 | ||
Keywords | Canis lupus, Central Asia, food habits, intraguild competition, Panthera uncia, scat analysis | ||||
Abstract | In the cold and arid mountains of Central Asia, where the diversity and abundance of wild ungulates are generally low, resource partitioning among coexisting carnivores is probably less distinct than in prey-rich areas. Thus, similar-sized carnivores are likely to compete for food. We compared the summer diets of snow leopards Panthera uncia and wolves Canis lupus in Sarychat-Ertash Reserve in the Tien-Shan mountains of Kyrgyzstan, based on analysis of genetically confirmed scats. Abundances of the principal prey species, argali Ovis ammon and Siberian ibex Capra sibirica, were estimated from field surveys. The diets consisted of few species, with high interspecific overlap (Pianka’s index50.91). Argali was the predominant prey, with .50% frequency of occurrence in both snow leopard and wolf scats. This was followed by Siberian ibex and marmots Marmota baibacina. Being largely unavailable, remains of livestock were not detected in any of the scats. In the snow leopard diet, proportions of argali and ibex were in line with the relative availabilities of these animals in the Reserve. This was in contrast to the diet of wolf, where argali occurred according to availability and ibex was significantly underrepresented. The high diet overlap indicates that the two predators might compete for food when the diversity of profitable, large prey is low. Competition may be more intense in winter, when marmots are not available. Hunting of argali and ibex outside the Reserve may be unsustainable and therefore reduce their abundances over time. This will affect both predators negatively and intensify competition for food. Reduction in ibex populations will directly affect the snow leopard, and the wolf is likely to be indirectly affected as a result of increased snow leopard predation of argali. |

Title | Restoring a keystone predator may endanger a prey species in a human-altered ecosystem: the return of the snow leopard to Sagarmatha National Park | Type | Journal Article | ||
Year | 2009 | Publication | Animal Conservation | Abbreviated Journal | |
Volume | 12 | Issue | Pages | 559-570 | |
Keywords | conservation, food habits, genetics, Hemitragus jemlahicus, Himalayan tahr, management, microsatellite, predation, presence, scat, scat analysis, snow leopard, Uncia uncia | ||||
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. | ||||

Abstract | In accordance with order of the Ministry of Nature and Tourism, zoologists of our association have made surveys in three ways such as reasons why snow leopards attack domestic animals, “Snow leopard” trial operation to count them and illegal hunting in territories of Khovd, Gobi-Altai, Bayankhongor, Uvurkhangai and Umnugobi provinces from September 2009 to January 2010. As result of these surveys it has made the following conclusions in the followings: Reason to hunt them illegally: the principal reason is that administrative units have been increased and territories of administrative units have been diminished. There have been four provinces in 1924 to 1926, 18 since 1965, 21 since 1990. Such situation limits movements of herdsmen completely and pastures digressed much than ever before. As result of such situation, 70% of pastures become desert. Such digression caused not only heads of animals and also number of species. Guarantee is that birds such as owls, cuckoo, willow grouse in banks of Uyert river, Burkhanbuudai mountain, located in Biger soum, Gobi-Altai province, which are not hunted by hunters, are disappearing in the recent two decades. For that reason we consider it is urgently necessary for the government to convert administrative unit structures into four provinces. This would influence herdsmen moving across hundreds km and pastures could depart from digression. Second reason: cooperative movement won. The issues related to management and strengthening of national cooperatives, considered by Central Committee of Mongolian People's Revolutionary Party in the meeting in March 1953 was the start of cooperatives' movement. Consideration by Yu. Tsedenbal, chairman of Ministers Council, chairman of the MPRP, on report “Result of to unify popular units and some important issues to maintain entity management of agricultural cooperatives” in the fourth meeting by the Central Committee of Mongolian People's Revolutionary Party /MPRP/ on December 16-17, 1959, proclaimed complete victory of cooperative. At the end of 1959, it could unify 767 small cooperative into 389 ones, unify 99.3 % of herdsmen and socialize 73.3 % of animals. The remaining of animals amount 6 million 163 thousands animals, and equals to 26.7% of total animals. This concerned number of animals related to the article mentioned that every family should have not more that 50 animals in Khangai zone and not more 75 animals in Gobi desert. It shows that such number could not satisfy needs of family if such number is divided into five main animals in separating with reproduction animals and adult animals. So herdsmen started hunt hoofed animals secretly and illegally in order to satisfy their meat needs. Those animals included main food of snow leopard such as ibex, wild sheep, and marmot. Third reason is that the state used to hunt ibex, which are main nutrition of snow leopards, every year. The administrative unit of the soum pursued policy to hunt ibex in order to provide meat needs of secondary schools and hospitals. That's why this affected decrease of ibex population. Preciously from 1986 to 1990 the permissions to hunt one thousands of wild sheep and two thousands of ibexes were hunt for domestic alimentary use every year. Not less than 10 local hunters of every soum used to take part in big game of ibexes. Also they hunted many ibexes, chose 3-10 best ibexes and hid them in the mountains for their consummation during hunting. Fourth reason: hunting of wolves. Until 1990 the state used to give prizes to hunter, who killed a wolf in any seasons of the year. Firstly it offered a sheep for the wolf hunter and later it gave 25 tugrugs /15 USD/. Every year, wolf hunting was organized several times especially picking wolf-cubs influenced spread and population of wolves. So snow leopard came to the places where wolves survived before and attack domestic animals. Such situation continued until 1990. Now population of ibexes has decreased than before 1990 since the state stopped hunting wolves, population of wolves increased in mountainous zones. We didn't consider it had been right since it was natural event. However population of ibexes decreased. Fifth reason: Global warming. In recent five years it has had a drought and natural disaster from excessive snow in the places where it has never had such natural disasters before. But Mongolia has 40 million heads of domestic animals it has never increased like such quantity in its history before. We consider it is not incorrect that decrease of domestic animals could give opportunities to raise population of wild animals. Our next survey is to make attempt to fix heads of snow leopards correctly with low costs. |
