Large carnivore species frequently predate and consume wild or domestic prey, which is referred to as food-related predation. Large carnivores can also hunt and kill prey exceeding their immediate needs (i.e., they do not consume prey), which is referred to as surplus predation. We used 173 records of livestock predations by gray wolves (Canis lupus; n = 133) and Persian leopards (Panthera pardus tulliana; n = 40) reported by governmental organizations of Iran during 2009–2019 to investigate food-related and surplus predation incidents of livestock. We found that for wolves, the number of reported surplus predation incidents was greater than that of food-related predation incidents during all 4 seasons (spring through winter), whereas for leopards, the number of food-related and surplus predation incidents were similar in all seasons. The number of livestock killed per surplus predation incident was greater for wolves than for leopards and that surplus predations by both species occurred more frequently within corrals than on free-range pastures. As corrals in most villages across Iran are poorly constructed and largely accessible to predators, we recommend that livestock owners enhance corral construction, use well-trained dogs during day and particularly at night, employ people to watch livestock at night, and use fire (e.g., torches) during night to scare carnivores. These strategies can mitigate predation incidents and corresponding economic losses, resulting in fewer losses of livestock, wolves, and leopards, as these two carnivore species are mainly killed by humans due to livestock predations across Iran.

Abstract Large carnivore species frequently predate and consume wild or domestic prey, which is referred to as food-related predation. Large carnivores can also hunt and kill prey exceeding their immediate needs (i.e., they do not consume prey), which is referred to as surplus predation. We used 173 records of livestock predations by gray wolves (Canis lupus; n = 133) and Persian leopards (Panthera pardus tulliana; n = 40) reported by governmental organizations of Iran during 2009–2019 to investigate food-related and surplus predation incidents of livestock.

These strategies can mitigate predation incidents and corresponding economic losses, resulting in fewer losses of livestock, wolves, and leopards, as these two carnivore species are mainly killed by humans due to livestock predations across Iran.

Context: Habitat loss and fragmentation are major threats to global biodiversity, especially for wide-ranging apex carnivores. The Persian leopard (Panthera pardus saxicolor) is an endangered species. Although populations of Persian leopards are declining, the species remains widely distributed across large areas of Iran. Aims: This study aimed to determine habitat suitability for Persian leopards in the Khaeiz and Sorkh protected area of south-western Iran and to identify the most significant factors influencing their habitat use/selection and spatial distribution. Methods: We performed species distribution modelling in two stages: First, we ran the model with three abiotic predictors: slope; aspect; and distance from water resources. In the second stage, modelling was conducted using three ecological predictors: caracal distribution; wild goat distribution; and livestock distribution. Ensemble modelling was applied based on five replicates of eight SDMs (species distribution models; GLM, CTA, FDA, GBM, ANN, MARS, RF and MaxEnt). Key results: We observed only minor differences in habitat suitability between the abiotic and ecological models. Habitat suitability for Persian leopards was higher in steeper areas, close to water resources and near the distribution of caracals, livestock and wild goats. The ecological model predicted 2.03% (329 ha) more suitable habitat than the abiotic model did. Conclusions: Most habitat suitability models focus on abiotic variables, but we found that ecological variables offer similar predictive power for determining the habitat suitability of Persian leopards. Implications: Habitat suitability models for Persian leopards can be used to guide conservation and management decisions. They are also useful indicating where conflicts between predators and humans may occur. The Persian leopard is an endangered species but remains widely distributed across large areas of Iran. An ensemble of eight species distribution models was developed for the species in Iran. A model including ecological predictors of occurrence predicted 2.03% (329 ha) more suitable habitat than the abiotic model. Habitat suitability for Persian leopards was higher in steeper areas, close to water resources, and near the distribution of caracals, livestock, and wild goats.. Photograph by Sadegh Poursalem.

Increasing anthropogenic pressures have caused drastic population decline of wild goats Capra aegagrus. The study aim was to determine habitat suitability and explore the factors influencing habitat selection and dispersal of wild goats in the Khaeiz and Sorkh protected area, southwestern Iran. We utilized ensemble modelling based on 25 replications of 10 species distribution models GLM (generalized linear model), GAM (generalized additive model), GBM (gradient boosting model), CTA (classification tree analysis), FDA (flexible discriminant analysis), ANN (artificial neural network), MARS (multivariate adaptive regression spline), RF (random forest), MaxEnt (maximum entropy), SRE (surface range envelope). Wild goat occurrence data were collected from 2019 to 2020 and related to five variables: predator distribution, slope, distance from road, distance from water resources, and normalized difference vegetation index (NDVI). We found that distribution of predators, slope, distance from water resources and distance from roads were the most important predictors of potential habitats for wild goats. The least important variable was NDVI. Probabilistic predictions suggest that only 5.89% of the area was highly suitable habitat, whereas 46.24% was unsuitable. Ensembling individually classified presence/absence maps further indicates that 79.72% of the study area was certainly unsuitable while only 8.06% was certainly suitable for wild goats. The results can help wildlife managers and policymakers work towards conservation and management goals and decreasing the conflicts between wildlife and humans. [ABSTRACT FROM AUTHOR]

This study was conducted in the Lorestan Province in the west of Iran with two objectives of identifying major environmental variables in spatial risk modeling and identifying spatial risk patches of livestock predation by the Persian leopard. An ensemble approach of three models of maximum entropy (MaxEnt), generalized boosting model (GBM), and random forest (RF) were applied for spatial risk modeling. Our results revealed that livestock density, distance to villages, forest density, and human population density were the most important variables in spatial risk modeling of livestock predation by the leopard. The center of the study area had the highest probability of livestock predation by the leopard. Ten spatial risk patches of livestock predation by the leopard were identified in the study area. In order to mitigate the revenge killing of the leopards, the findings of this study highlight the imperative of implementing strategies by the Department of Environment (DoE) to effectively accompany the herds entering the wildlife habitats with shepherds and a manageable number of guarding dogs. Accordingly, the identified risk patches in this study deserve considerable attention, especially three primary patches found in the center and southeast of Lorestan Province. [ABSTRACT FROM AUTHOR]

Mammals are under threat worldwide due to deforestation, hunting, and other human activities. In Iraq, a total of 93 species of wild mammals have been recorded including species with global conservation concern. Bamo Mountain is situated within the Zagros Mountains in northern Iraq which is a suitable habitat for wild mammals. Due to scarcity of the field survey efforts and cryptic behavior, monitoring of the wild mammals fauna in Zagros Mountain seems challenging. Therefore, we used a camera trap which seems to be an ideal way to determine species diversity of wild mammals in Bamo Mountain. Moreover, interviews with local villagers were performed. The mammalian diversity of Bamo Mountain is not fully explored but seemed threatened by local extinction due to poaching and wildlife trafficking, minefields, and annual fires. In this study, a total of eight species of wild mammals were recorded for the first time in Bamo Mountain using camera trap method including the Persian leopard Panthera pardus saxicolor Pocock, 1927, and the Wild goat Capra aegagrus Erxleben, 1777, flagship and key species of conservation concern. As far as it is concerned, the major threats on the wild mammals were discussed and some important points were highlighted towards the establishment of the protected area in Bamo Mountain.

Large carnivores are currently disappearing from many world regions because of habitat loss, prey depletion, and persecution. Ensuring large carnivore persistence requires safeguarding and sometimes facilitating the expansion of their populations. Understanding which conservation strategies, such as reducing persecution or restoring prey, are most effective to help carnivores to reclaim their former ranges is therefore important. Here, we systematically explored such alternative strategies for the endangered Persian leopard (Panthera pardus saxicolor) in the Caucasus. We combined a rule‐based habitat suitability map and a spatially explicit leopard population model to identify potential leopard subpopulations (i.e., breeding patches), and to test the effect of different levels of persecution reduction and prey restoration on leopard population viability across the entire Caucasus ecoregion and northern Iran (about 737,000 km2). We identified substantial areas of potentially suitable leopard habitat (~120,000 km2), most of which is currently unoccupied. Our model revealed that leopards could potentially recolonize these patches and increase to a population of >1,000 individuals in 100 yr, but only in scenarios of medium to high persecution reduction and prey restoration. Overall, reducing persecution had a more pronounced effect on leopard metapopulation viability than prey restoration: Without conservation strategies to reduce persecution, leopards went extinct from the Caucasus in all scenarios tested. Our study highlights the importance of persecution reduction in small populations, which should hence be prioritized when resources for conservation are limited. We show how individual‐based, spatially explicit metapopulation models can help in quantifying the recolonization potential of large carnivores in unoccupied habitat, designing adequate conservation strategies to foster such recolonizations, and anticipating the long‐term prospects of carnivore populations under alternative scenarios. Our study also outlines how data scarcity, which is typical for threatened range‐expanding species, can be overcome with a rule‐based habitat map. For Persian leopards, our projections clearly suggest that there is a large potential for a viable metapopulation in the Caucasus, but only if major conservation actions are taken towards reducing persecution and restoring prey.

Abstract Gray literature and data from unpublished sources can provide important scientific information that has not been published scientifically. The Persian leopard (hereafter leopard) Panthera pardus saxicolor is classed as endangered on the Red List of the International Union for Conservation of Nature and also is one of the least‐studied subspecies of leopard. It occurs in the Caucasus and Central and Southwest Asia. Iran contains more than 75% of the leopard's extant range, and the leopard population in this country serves as a source for neighboring countries. In this study, we determined the distribution and human‐caused mortality of leopards in Iran, by reviewing unpublished data and Farsi gray literature (which includes government reports) between 1 January 2010 and 30 December 2018. We created the most recent distribution map of the leopard in Iran. Our data display that human‐caused mortality of leopard in Iran mostly includes poaching and intentional poisoning, and roadkill.

A carcass of a Persian leopard (Panthera pardus saxicolor) that was inadvertently killed in a car accident in Golestan National Park, North-Iran, was referred to the laboratory of the Department of Environment in Golestan Province. The carcass was infested with hard ticks. Five ticks were collected and identified as Ixodes ricinus (one female) and Rhipicephalus turanicus (four males). These hard ticks are major vectors of some important microorganisms of veterinary and medical significance. This is the first detection of I. ricinus and R. turanicus in the Persian leopard.

Persian leopards Panthera pardus saxicolor have been extirpated from over 84% of their historic range and are now limited to rugged landscapes of West Asia and the Caucasus. Understanding and maintaining genetic diversity and population connectivity is important for preventing inbreeding and genetic drift, both of which can threaten population viability. All previous analyses of intraspecific genetic variation of West Asian leopards based on the NADH dehydrogenase subunit 5 gene have reported low mitogenomic diversity. In the current study, we sequenced 959 bp of the mtDNA cytochrome b gene to describe the spatial genetic structure of 22 wild Persian leopards across Iran, which hosts most of the subspecies extant range. The findings based on phylogenetic trees and median-joining network indicated that leopards from Iran formed a distinct subclade, i.e., P. p. saxicolor. The AMOVA analysis showed significant differentiation (88.55%) between the subclades of Persian leopards and other Asian leopards. The lowest levels of haplotype (0.247) and nucleotide (0.00078) diversity were estimated in Persian leopards from Iran. Mitochondrial genome sequencing revealed only two closely related haplotypes. There was no evidence for recent sudden demographic expansion scenario in Persian leopards. The low diversity in cytochrome b gene could potentially be brought about by selective pressure on mitochondria to adapt to oxidative stress and higher metabolic rates in cold environments.

Illegal hunting of ungulates can reduce the prey base of carnivores, which can increase human–carnivore conflict (HCC) through livestock depredation. However, the relationship between ungulate poaching, wild prey abundance and livestock depredation has rarely been empirically studied.We surveyed 18 sites across the Hyrcanian forest in northern Iran; a global biodiversity hotspot under pressure from illegal hunting of ungulates, prey depletion, livestock grazing and HCC. We conducted three field surveys across 1,204 km in 93 4 × 4 km cells to count signs of ungulate poaching as well as encounters with livestock and prey species of the Persian leopard Panthera pardus saxicolor and the grey wolf Canis lupus. We documented sheep/goat and cattle depredation from interviews with 201 herders and analysed the effects of illegal hunting of ungulates, forest cover, IUCN categories of reserves, elevation, distance to villages, and wild prey and livestock encounter rates on carnivore depredation rates using generalized linear models.Illegal hunting of ungulates was the most influential depredation predictor. An increase in the illegal hunting of ungulates by one sign/km significantly increased depredation by up to four times. We also found significantly lower levels of ungulate poaching in national parks (IUCN category II) compared to protected areas (V), wildlife refuges (IV) and no‐hunting areas, though poaching signs were frequently found in most cells (58%). Encounters with livestock was inversely linked to wild prey species, but positively coupled with signs of ungulate poaching.Synthesis and applications. Our study reveals that: (a) an increase in the intensity of illegal hunting of ungulates can intensify livestock depredation by carnivores; (b) future efforts in reducing human‐carnivore conflict to acceptable levels require a combination of law enforcement, prey recovery approaches and mitigation measures; (c) it is essential to understand the root causes of poaching to help minimize human‐carnivore conflict (HCC).

Land use changes in suitable areas, habitat loss, and fragmentation are likely to be the most important consequences of climate change for wildlife populations. Yet, little is known about the response of large carnivores to climate change, globally and regionally. In this study, we utilized the ensemble modeling based on six species distribution models in order to predict the spatial vulnerability of the globally endangered Persian leopard (Panthera pardus saxicolor) to climate change in Chaharmahal and Bakhtiari Province, a semi-arid region in Iran. We showed that about 12.12 to 22.38% of leopard habitats in the area may be lost by 2050 due to climate change under four representative concentration pathways (RCPs) within the framework of two general circulation models (GCMs). In contrast, 1.87 to 13.01% of currently unsuitable habitats can become suitable with climate change. Overall, a considerable portion of the leopard range will remain intact under global warming, but still habitat loss to climate change will vary from 5.89 to 14.59%. Thus, large-scale but locally focused and flexible conservation strategies should be applied in intact and sensitive areas so that to prevent the intensification of anthropogenic threats such as overgrazing and forest degradation from collection of firewood, charcoal, and medicinal plants under changing climate.

The implementation of the programme for the reintroduction of the Persian leopard in the Caucasus in Russia allowed carrying out a detailed video monitoring of various aspects of this subspecies' life under captive conditions in the «Center of the leopard recovery in the Caucasus». The most important stage of this programme was the formation of couples and the progeny getting of adult individuals caught in their natural environment and placed into a closed aviary. A complex sexual behaviour of leopards, while having different stages of the estrous cycle, could be identified by manifestation of characteristic features in various stages. There is an increase in both the motion behaviour as well as in the marking activity during proestrus; the cozying that helps to maintain the sexual activity of the male and the adopting of the receptive pose of the female during the estrus; avoidance of mating by the female during the proestrus stage; transition of the mating initiative to the male as well as passive behaviour of the female during the metaestrus stage. A large number of matings is caused by the species' biology. The leopard belongs to the animals with an «instigated» ovulation. Therefore the multiple coituses stimulate the maintaining of a high concentration of estrogens in the blood and promote the ovulation of follicles. As a result, we have concluded that the form of female sexual behaviour (with permissible error) can indicate the functional activity of the ovaries and the corpora lutea, as well as it allows determining the beginning and duration of the stages of the estrous cycle.

Describing predation patterns and especially estimating kill and consumption rates is essential for understanding the functional responses of predators. An understanding of the carrying capacity of the landscape, based on prey availability, also helps to formulate recovery plans for persecuted species. We studied the feeding behavior of the Persian leopard (Panthera pardus saxicolor) in Tandoureh National Park (355 km2) in northeastern Iran, near the Turkmenistan border. Between September 2014 and May 2017, we collared and monitored 6 adult leopards (5 males and 1 female) using GPS-satellite Iridium collars. We investigated 310 clusters of fixes as likely to be kill sites. In total, 130 kills were identified to species, suggesting a mean kill rate of approximately 3.3 ± 0.3 (SE) kills/month per adult male leopard, which is higher than reported by most previous studies. The leopards varied considerably in the time they spent outside the national park; only 1 individual appeared to subsist mainly by raiding livestock. The availability of medium-sized ungulates at adequate densities is likely to be important for future leopard conservation efforts. The management of problem individuals also may promote coexistence of humans and leopards, even in prey-rich areas. [ABSTRACT FROM AUTHOR]

The conservation of top predators' habitats such as the leopard ( Panthera pardus) is one of the most effective ways to conserve biodiversity because of wide home range and habitat requirements. Accordingly, in this study, we used species' habitat suitability modeling to survey the current and future habitat suitability of the Persian leopard in Iran. Sixty-two change scenarios (CC scenarios) (by 19 global climate models under four representative concentration pathways) were used to model future habitat suitability of the Persian leopard in Iran by MaxEnt model. Our results showed that prey availability is a key habitat variable to predict habitat suitability for leopard, and Capra aegagrus is the most important prey for this species in Iran. So, the distribution of Capra aegagrus plays an important role to model habitat suitability of the Persian leopard in Iran. The results also showed that 63% of the current suitable habitats will be decreased over 63 years. The results also showed a considerable change of suitable habitats which can threat long-term survival of this species in Iran. Our results revealed that one of the most important threats for the Persian leopard in future is changing suitable habitat due to climate change. Therefore, identifying and protecting potential habitats and minimizing human activities within areas are essential for current and future conservation. [ABSTRACT FROM AUTHOR]

Three feline hemoplasma species exist in felids: Mycoplasma haemofelis, ‘ Candidatus Mycoplasma haemominutum’, and ‘ Candidatus Mycoplasma turicensis’. The aims of the study were to determine the presence of, and molecularly characterize, any hemoplasmas in wild felids, including the endangered Persian leopard in Iran, the Middle East. Blood samples were collected from 19 wild felids, including three Persian leopards. Using species-specific hemoplasma PCRs and ELISA serological testing for feline leukaemia virus and feline immunodeficiency virus (FIV), two Persian leopards were found to be infected with ‘ Ca. M. haemominutum’ and were seropositive for FIV. Partial 16S rRNA gene sequences were generated for these ‘ Ca. M. haemominutum’ species and subsequent phylogenetic analysis revealed 97.70% to 99.45% sequence identity with those found in domestic cats from Iran and other countries. This study confirms the presence of ‘ Ca. M. haemominutum’ and concurrent FIV antibody in wild felids in Iran. This represents the first report of hemoplasma in wild felids in the Middle East as well as the first report of infection in Persian leopards. [ABSTRACT FROM AUTHOR]

Mammalian carnivores often cause problems for people by preying on domestic stock. Exploring the factors that affect people's attitudes to predators, in particular the circumstances when some degree of loss is tolerated, is needed for developing predator management plans. When more than one species of predator is involved, there may be unexpected interactive effects in shaping people's tolerance. We addressed this hypothesis in a west Asian multi-predator montane landscape with high density of both wild ungulates and livestock harboring two large predators, Persian leopard and grey wolf. A semi-structured questionnaire survey of herders residing around Tandoureh, Salouk and Sarigol National Parks, northeastern Iran was carried out. The perceived role of leopards in depredation was negligible compared with that of wolves which were reported to be more frequent stock raiders and responsible for an average of 5.7 times more annual losses per herd by than were leopards. Non-predatory causes of mortality, particularly diseases, were clearly the major threat to livestock. Interviewed herders showed different attitudes toward each predator. Regardless of any recent occurrence of stock raiding by wolves, they were predominantly considered negatively. Although people showed mainly positive attitudes toward leopards, respondents who reported more wolf attacks tended to have more negative attitudes toward leopards. Hence, in multiple predator ecosystems, peoples' attitudes toward each species may be affected by the perceived activity of other predators. Often neglected in conservation programs, this phenomenon is clearly important in sustaining people tolerance particularly if endangered large predators are involved. [ABSTRACT FROM AUTHOR]

Persian leopard (Panthera pardus saxicolor) is the largest P. pardus subspecies in the world. But according to the sharp decline and extinction of populations in some areas, more attention to this subspecies in aspect of genetic conservation is of utmost importance. The goal of this study was to genetic and phylogenetic analysis of D-Loop region in Persian Leopard. Six biological samples of leopard bone and skin were prepared from Tandooreh National Park in Khorasan Razavi province from 2008 to 2011. After DNA extraction, 800bp fragment of the mitochondrial D-Loop was amplified with universal primers, L15926 and H16498 under polymerase chain reaction. Amplified fragments were sequenced with ABI 3130 automated machine under Sanger method. After editing the sequences, the results were compared with sequences from other studies to determine the genetic distances. Variations were not observed in the nucleotide sequences obtained in this study. Using the Neighbor-Joining phylogenetic test results showed that the Persian leopard is in group of P. pardus and its haplotype is the same with saxicolor.

Ranger stations are essential to combat poaching in protected areas and the distance from ranger stations is sometimes used as a proxy for poaching levels and law enforcement intensity. However, the influence of the spatial distribution of ranger stations on wildlife abundance and population structure has rarely been investigated. We evaluated the abundance and distribution of urial sheep O vis vignei and Persian leopard P anthera pardus saxicolor in the steppe of Golestan National Park in northeastern Iran. The spatial distribution of these species in regard to anthropogenic (distances to ranger stations, villages and park border) and environmental variables (distance to water resources, average slope and normalized difference vegetation index) was assessed using systematic line transect sampling (186 km) and camera trapping (1150 trap nights). The studied steppe area is divided into three management zones differing in the number of ranger stations and their position with respect to park boundaries. The results of multivariate analyses highlighted that the distance to ranger stations was negatively related to the size and density of urial clusters and the most important variable in explaining urial distribution. Moreover, the distance to park borders influenced urial cluster density. Leopard abundance was positively associated with urial density but was less affected by the other variables tested. We found urial densities in the three management zones to range from 0.15 ± se 0.09 individuals km−2 (zone with just one station outside the park) to 21.77 ± se 7.92 individuals km−2 (zone with three stations). Taking into account these results and historical data on ungulate abundance and distribution in these management zones, we conclude that law enforcement from ranger stations has shaped current patterns of ungulate distribution. These results confirm that a good coverage (both numbers and locations) of ranger stations is of central importance for the management of protected areas. [ABSTRACT FROM AUTHOR]

We carried out a dietary analysis of Persian Leopards, Panthera pardus saxicolor, in a temperate region in north-eastern Iran, where the largest population nucleus exists across the subspecies range. We investigated 113 faecal samples collected between February 2009 and March 2010 in Golestan National Park. Faecal analysis revealed that leopards predominantly preyed upon wild ungulates, with the Wild Boar, Sus scrofa, being the most important prey species in terms of frequency and biomass. Eleven different prey items were identified, 7 of which were ungulates, comprising 99% of the total food items. We also found a spatial pattern in the prey composition of leopards: cervids were predominantly found in forest landscapes, whereas Wild Sheep, Ovis orientalis, was mainly found in steppe habitats, revealing the leopards' predation on medium- to large-sized ungulates. Livestock remains were mainly extracted from steppe samples, but the overall contribution to the leopard diet pattern (approximately 8.5% of consumed biomass) suggested that conflict with human communities, at least within the investigated core parts of the National Park, is not a major concern. The study provides the first illustration of the Persian Leopard's dietary composition in a temperate area with a relatively high diversity of available prey, and can be a baseline for future investigation and human-leopard interaction monitoring.

Ranging across montane areas of west Asia, the endangered Persian leopard Panthera pardus saxicolor is a flagship species for biodiversity conservation in the Caucasus Eco-region. Despite recent reduction in occupancy and number within the range countries, the subspecies still exists in large areas within Iran, including the northwest which is considered the only promising source from which this leopard might recolonize its former range. In this context, we sought to elucidate the species' status and habitat requirements, and to evaluate the effectiveness of protected areas in safeguarding its long-term persistence. We report 150 locations where the Persian leopard was recorded across six provinces in the Iranian Caucasus Eco-region. These records informed a consensus species distribution modeling approach using 14 uncorrelated environmental variables (landcover, topographic, anthropogenic and climatic features) to explore the distribution of habitats suitable for the leopards. Using electrical-circuit theory we then explored connectivity between the usable habitats as revealed by this model. Unsurprisingly, our models confirmed that prey availability and the avoidance of humans were the primary influences on leopard distribution in the region. Two main landscapes were revealed to be suitable for the leopard but only 30% of their 20,026.9 km 2 area is officially protected. The Alborz landscape hosted the larger population nucleus and majority of breeding occurrences. Modeled connectivity revealed that persistence of the Persian leopard population in the boundary landscape and the broader Lesser Caucasus Mountains is dependent on trans-boundary movements through southern Azerbaijan. We conclude that it is a priority that international collaboration secures the Persian leopard's conservation in the wider landscape spanning the borders of Caucasian countries.

The article presents a case study which investigates the Persian leopards (Panthera pardus) found in the Caucasus region. Topics discussed include a description of the survey area used by researchers in the study, the use of visual recognition methods and genetic profiling to identify the individual leopard residing in the survey area, and a comprehensive analysis of the results.

Management controversies arise when both of the prey and predator in an ecosystem are species of conservation concern. We investigated trophic interactions between the endangered Persian leopard ( Panthera pardus saxicolor) and a declining mountain ungulate, urial wild sheep ( Ovis vignei), on a high-altitude steppe of Iran. During two consecutive photo-trapping seasons of 1,300 nights in total, a minimum population of four adult leopards (one female and three males) was documented. Scat analysis indicated that urial wild sheep was the staple of the leopard diet with 48.44 % of total biomass consumed. Remains of domestic livestock in leopard scats were negligible yet alarming (14.53 % biomass consumed), followed by wild pigs (8.13 %) and wild goat (1.26 %). Financial costs of leopard depredation to livestock breeders during our study period were comparatively lower than livestock-leopard conflict hotspots across Iran. Using distance sampling, urial density was 15.8 individuals km (±SE 6.2), and a total biomass of 47,621.5 kg for wild ungulates in the study area was estimated. We estimated that the annual removal rate of urial by leopards during our study period was 9.4 % of the total urial population. We suggest that continuous monitoring of the leopard and prey populations to assess predation impact should be considered, particularly in areas where a single species comprises a remarkable proportion of the leopard diet. In the meantime, assessing probable conflicts with local communities is recommended as a parallel management action to ensure long-term human-leopard coexistence. Our findings will aid wildlife managers in prey-depleted arid environments of western Asia to identify susceptible wild prey populations to predation by large carnivores; hence, significantly contribute in development and implementation of effective conservation measures to mitigate management conflicts.
