Common Leopard Panthera Pardus Research Articles

A case report on chronic renal disease in a captive wild Leopard Panthera pardus (Mammalia: Carnivora)

A 22-year-old female Common Leopard Panthera pardus at Dhauladhar Nature Park, Gopalpur Zoo was reported to show abnormal behavior in its feeding cubicle during the evening hours and was later found dead. The carcass was presented for necropsy examination at the Department of Pathology, DGCN COVAS, Palampur. Necropsy examination showed enlarged kidneys with completely adhered renal capsule. Lungs and intestine exhibited oedema and hemorrhages, respectively. The histopathological examination found severe necrotic changes with degenerations and fibrosis. Inter-tubular and glomerular collagenous fibrous tissue was confirmed by Masson’s trichrome staining. The animal is speculated to have died primarily due to chronic renal failure with associated pathologies in lungs and intestine.

Crop raiding and livestock predation by wildlife in Khaptad National Park, Nepal

Crop raiding and livestock predation are major conservation problems throughout most protected areas in Nepal, including the Khaptad National Park (KNP). However, no information exists on the extent of crop raiding, livestock predation, and animal attacks among villages surrounding KNP. We conducted a survey of 304 households in 30 villages in four districts (Bajhang, Bajura, Doti, and Achham) in the buffer zone of KNP between 24 May and 20 June 2019, using the snowball sampling technique. All households experienced numerous major incidents of crop raiding between April 2017 and May 2019. Major wildlife involved were Wild Boar Sus scrofa, Himalayan Black Bear Ursus thibetanus, Rhesus Macaque Macaca mulatta, Barking Deer Muntiacus vaginalis, Common Leopard Panthera pardus, Golden Jackal Canis aureus, and Porcupine Hystrix spp. Of the 304 households, all had their crops raided over the past two years, 55.5% (n = 169) faced livestock predation, and 2% (n = 6) attacks resulting in death or injury. Over 40% of households reported taking mitigation measures to minimize crop raiding. Common measures such as night guarding, noise making, use of scarecrows, watch dogs, and fencing were practiced. More than half of respondents had negative opinions towards wildlife but they still believed that wildlife should be conserved. There was no or negligible correlation between general opinion of respondents towards wildlife and wildlife conservation with their education, sex, or involvement in natural resources management group. We established baseline information on crop raiding and livestock predation in villages surrounding KNP. Gathered information will be transmitted to relevant authorities to design and implement measures to mitigate such conflicts.

Blessing the rains down in Africa: spatiotemporal behaviour of the crested porcupine <em>Hystrix cristata</em> (Mammalia: Rodentia) in the rainy and dry seasons, in the African savannah

The assessment of habitat selection and temporal patterns of activity rhythms is paramount for wildlife conservation. Studies on behavioural ecology of wild mammals are particularly challenging in tropical areas, mostly when involving rare or elusive species. Despite being a common species in Italy, the crested porcupine Hystrix cristata is threatened of extinction throughout most of its sub-Saharan range. All available information on the ecology of this species has been collected in Italy, whereas no data is present in the scientific literature on spatiotemporal behaviour of this large rodent in Africa. In this work, we attempted to determine habitat selection and temporal patterns of activity rhythms of the crested porcupine in northern Benin and neighbouring countries, through intensive camera-trapping. We collected a total of 146 records of crested porcupine, 91 in the dry season (October-March) and 55 in the rainy season (April-September). Porcupines used most habitats in proportion to their local availability, while selecting rock outcrop formations (possibly used as shelter sites) and avoiding open areas, wetlands and gallery forests. A mostly nocturnal behaviour was confirmed throughout the year, with some diurnal activity at the start and at the end of the rainy season. The importance of rains in determining birth peak has been also showed, with juvenile individuals always observed at the start and at the end of the rainy season. Full moon always inhibited activity of this large rodent, most likely evolved as an antipredatory behaviour to limit encounters with potential predators (common leopard Panthera pardus, spotted hyaena Crocuta crocuta and honey badger Mellivora capensis) and humans. Poaching pressure towards porcupines in West Africa is strong. Porcupines are killed for the traditional medicine, for their meat and because they are widely considered as a crop pest. This assessment should therefore be used as a basic tool to design conservation plans to preserve this rodent species in its native range.

Mammals of the Bhagirathi basin, Western Himalaya: understanding distribution along spatial gradients of habitats and disturbances

AbstractUnderstanding the distribution of wildlife species and their response to diverse anthropogenic pressures is important for conservation planning and management of wildlife space in human-dominated landscapes. Assessments of anthropogenic impacts on mammals of the Indian Himalayan Region have mostly been limited to locations inside protected areas. We studied the occurrence of mammals in an unexplored landscape, the 7,586 km2 Bhagirathi basin, at an altitude of 500–5,200 m. The basin encompasses wilderness areas of various habitat types and protection status that are exposed to a range of anthropogenic pressures. Camera trapping at 209 locations during October 2015–September 2017 confirmed the occurrence of 39 species of mammals, nine of which are categorized as threatened (four Vulnerable, five Endangered) and four as Near Threatened on the IUCN Red List. We recorded five mammal species that were hitherto undocumented in Uttarakhand State: the argali Ovis ammon, Tibetan sand fox Vulpes ferrilata, woolly hare Lepus oiostolus, Eurasian lynx Lynx lynx and woolly flying squirrel Eupetaurus cinereus. In addition, we recorded two Endangered species, the dhole Cuon alpinus and tiger Panthera tigris. Threatened species such as the sambar Rusa unicolor, common leopard Panthera pardus and Asiatic black bear Ursus thibetanus occur in a wide variety of habitats despite anthropogenic disturbance. We recorded the snow leopard Panthera uncia in areas with high livestock density but temporally segregated from human activities. The musk deer Moschus spp. and Himalayan brown bear Ursus arctos isabellinus were recorded in subalpine habitats and appeared to be less affected by human and livestock presence. Our findings highlight the potential of the Bhagirathi basin as a stronghold for conservation of several threatened and rare mammal species.

First photographic record of marbled cat Pardofelis marmorata Martin, 1837 (Mammalia, Carnivora, Felidae) in Nepal

The marbled catPardofelismarmoratais a Near Threatened small felid. The cat’s presence in Nepal is based on an anecdote. A camera trap-based study to access diversity and abundance of terrestrial mammals in eastern Nepal accumulated 3,014 camera trap days and resulted in 5,176 photographs of 17 medium-large sized mammal species. Amongst them, a marbled cat was captured at a single camera trap station in January 2018. The camera trap-capturing the marbled cat was located in the secondary forest at an altitude of 2,750 m a.s.l., dominated by free-ranging cattle close to a permanent human settlement (1.4 km) and a temporary cattle herding camp (0.4 km). This is the first photographic evidence of a marbled cat in Nepal. In this survey, we also recorded three other felid species: common leopardPantherapardus, Asiatic golden-catCatopumatemminckiiand leopard catPrionailurusbengalensis. We recommend detailed year-round camera trap surveys in the mid-hills of eastern Nepal along with research on adaptation of the small felids to human-dominated areas and assessment of immediate threats for preparing sound conservation management plans of the marbled cat and its sympatric species. Initiation of conservation programmes engaging localdokpa(herders) is necessary.

Predation may counteract climatic change as a driving force for movements of mountain ungulates

Temperature variations are expected to influence altitudinal movements of mountain herbivores and, in turn, those of their predators, but relevant information is scarce. We evaluated monthly relationships between temperature and altitude used by a large mountain-dwelling herbivore, the Himalayan tahr Hemitragus jemlahicus, and its main predator, the snow leopard Panthera uncia, in an area of central Himalaya for five consecutive years (2006–2010). In contrast to expectations, there was no significant direct relationship between altitude of tahr sightings and temperature. The mean altitude of tahr sightings decreased by c. 200m throughout our study. As expected, snow leopard movements tracked those of tahr, although the core area of the snow leopard did not move downwards. Tahr remained the staple of the snow leopard diet: we suggest that the former did not move upwards in reaction to higher temperature to avoid encounters with the latter. Avoidance of competition with the larger common leopard Panthera pardus at lower altitudes could explain why snow leopards did not shift their core area downwards. Apparently, interspecific interactions (predation; competition) influenced movements of Himalayan tahr and snow leopards more than climatic variations.

Examining Temporal Sample Scale and Model Choice with Spatial Capture-Recapture Models in the Common Leopard Panthera pardus.

Many large carnivores occupy a wide geographic distribution, and face threats from habitat loss and fragmentation, poaching, prey depletion, and human wildlife-conflicts. Conservation requires robust techniques for estimating population densities and trends, but the elusive nature and low densities of many large carnivores make them difficult to detect. Spatial capture-recapture (SCR) models provide a means for handling imperfect detectability, while linking population estimates to individual movement patterns to provide more accurate estimates than standard approaches. Within this framework, we investigate the effect of different sample interval lengths on density estimates, using simulations and a common leopard (Panthera pardus) model system. We apply Bayesian SCR methods to 89 simulated datasets and camera-trapping data from 22 leopards captured 82 times during winter 2010–2011 in Royal Manas National Park, Bhutan. We show that sample interval length from daily, weekly, monthly or quarterly periods did not appreciably affect median abundance or density, but did influence precision. We observed the largest gains in precision when moving from quarterly to shorter intervals. We therefore recommend daily sampling intervals for monitoring rare or elusive species where practicable, but note that monthly or quarterly sample periods can have similar informative value. We further develop a novel application of Bayes factors to select models where multiple ecological factors are integrated into density estimation. Our simulations demonstrate that these methods can help identify the “true” explanatory mechanisms underlying the data. Using this method, we found strong evidence for sex-specific movement distributions in leopards, suggesting that sexual patterns of space-use influence density. This model estimated a density of 10.0 leopards/100 km2 (95% credibility interval: 6.25–15.93), comparable to contemporary estimates in Asia. These SCR methods provide a guide to monitor and observe the effect of management interventions on leopards and other species of conservation interest.

Abundance and density estimates for common leopard Panthera pardus and clouded leopard Neofelis nebulosa in Manas National Park, Assam, India

AbstractEffective conservation of rare carnivores requires reliable estimates of population density for prioritizing investments and assessing the effectiveness of conservation interventions. We used camera traps and capture–recapture analysis to provide the first reliable abundance and density estimates for the common leopard Panthera pardus and clouded leopard Neofelis nebulosa in Manas National Park, India. In 57 days of camera trapping, with a total of 4,275 camera-trap days, we photo-captured 27 individually identified common leopards (11 males, 13 females and three unidentified), and 16 clouded leopards (four males, five females and seven unidentified). The abundance estimates using the Mh jackknife and Pledger model Mh were 47.0 and 35.6, respectively, for the common leopard, and 21.0 and 25.0, respectively, for the clouded leopard. Density estimates using maximum likelihood spatially-explicit capture–recapture were 3.4 ± SE 0.82 and 4.73 ± SE 1.43 per 100 km2 for the common and clouded leopards, respectively. Spatially-explicit capture–recapture provided more realistic density estimates compared with those obtained from conventional methods. Our data indicates that camera trapping using a capture–recapture framework is an effective tool for assessing population sizes of cryptic and elusive carnivores such as the common and clouded leopards. The study has established a baseline for the long-term monitoring programme for large carnivores in Manas National Park.

Royal Manas National Park, Bhutan: a hot spot for wild felids

AbstractThe non-uniformity of the distribution of biodiversity makes allocation of the limited resources available for conservation of biodiversity a difficult task. Approaches such as biodiversity hotspot identification, endemic bird areas, crisis ecoregions, global 200 ecoregions, and the Last of the Wild are used by scientists and international conservation agencies to prioritize conservation efforts. As part of the biodiverse Eastern Himalayan region, Bhutan has been identified as a conservation priority area by all these different approaches, yet data validating these assessments are limited. To examine whether Bhutan is a biodiversity hot spot for a key taxonomic group, we conducted camera trapping in the lower foothills of Bhutan, in Royal Manas National Park, from November 2010 to February 2011. We recorded six species of wild felids of which five are listed on the IUCN Red List: tiger Panthera tigris, golden cat Pardofelis temminckii, marbled cat Pardofelis marmorata, leopard cat Prionailurus bengalensis, clouded leopard Neofelis nebulosa and common leopard Panthera pardus. Our study area of 74 km2 has c. 16% of felid species, confirming Bhutan as a biodiversity hot spot for this group.

Large mammals surviving conflict in the eastern forests of Afghanistan

AbstractWe used transect and camera-trap surveys and DNA identification of scat samples to provide the first update since 1977 of large mammals in the montane forests of the conflict-ridden province of Nuristan in eastern Afghanistan. Nuristan contains a range of habitats from oakQuercusspp. forests to treeless alpine steppes that historically hosted populations of markhorCapra falconeri, Asiatic black bearUrsus thibetanus, grey wolfCanis lupusand common leopardPanthera pardus, among others. Surveys conducted in 2006–2009 in an area of 1,100 km2by the Wildlife Conservation Society confirmed the presence of some of these species, and also recorded the common palm civetParadoxurus hermaphroditus, previously unknown from Afghanistan; this extends the westernmost boundary for this species. The most commonly recorded species, as determined by direct sightings, scat identification or camera-trap photographs, were the Indian crested porcupineHystrix indica, red foxVulpes vulpesand a canid (grey wolf or golden jackalCanis aureus). Despite indications of significant habitat loss and unsustainable hunting, globally important species persist in the area and targeted conservation programmes are required for the protection of these species, the forests they inhabit and the surrounding communities who depend on both for their survival.

Summer diet composition of the Common Leopard Panthera pardus (Carnivora: Felidae) in Nepal

The Common Leopard Panthera pardus is one of the most widely distributed of all big cats. It is a threatened species throughout its range due to the degradation of natural habitat, poaching and persecution as a killer of humans and livestock. The purpose of this study was to determine the composition of the Common Leopard diet in the Dhorpatan Hunting Reserve (DHR) of Nepal. Among prey species Barking Deer (Muntiacus muntjak) were observed most frequently (18%) in leopard scats, while Blue Sheep (Pseudois nayaur) were observed less frequently (6%).

War and wildlife: a post-conflict assessment of Afghanistan's Wakhan Corridor

Prior to the last two decades of conflict, Afghanistan?s Wakhan Corridor was considered an important area for conservation of the wildlife of high altitudes. We conducted an assessment of the status of large mammals in Wakhan after 22 years of conflict, and also made a preliminary assessment of wildlife trade in the markets of Kabul, Faizabad and Ishkashem. The survey confirmed the continued occurrence of at least eight species of large mammals in Wakhan, of which the snow leopard Uncia uncia and Marco Polo sheep Ovis ammon are globally threatened. We found evidence of human-wildlife conflict in Wakhan due to livestock depredation by snow leopard and wolf Canis lupus. Large mammals are hunted for meat, sport, fur, and in retaliation against livestock depredation. The fur trade in Kabul is a threat to the snow leopard, wolf, lynx Lynx lynx and common leopard Panthera pardus.

Status of the snow leopard Panthera uncia in Northwest India

A nine-month survey of snow leopard Panthera uncia status was carried out in selected regions of India's three northwestern Himalayan states. Evidence of snow leopard presence was most abundant in central Ladakh, decreased southward toward the crest of the Himalaya, and was least on the southern side of the main Himalaya, where evidence of common leopard Panthera pardus was also found near the timberline. Prey populations, primarily blue sheep Pseudois nayaur and Asiatic ibex Capra ibex, were also more plentiful in the areas surveyed to the north of the main Himalaya. Perhaps 400 snow leopard occur throughout northwest India. Several national parks in India's Himalaya probably include small numbers of snow leopard, but the stronghold of this species in India is apparently the trans-Himalayan ranges in Ladakh where new parks and reserves are being established, some in association with a ‘snow leopard recovery programme’ of the state of Jammu and Kashmir and a ‘Project Snow Leopard’ of the central Indian government. Because of the generally low density of snow leopard, conservation measures must also be considered within the large areas of its range lying outside parks and reserves.
