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.

An understanding of local perceptions of carnivores is important for conservation and management planning. In the central Himalayas, Nepal, we interviewed 428 individuals from 85 settlements using a semi-structured questionnaire to quantitatively assess local perceptions and tolerance of snow leopards and wolves. We used generalized linear mixed effect models to assess influential factors, and found that tolerance of snow leopards was much higher than of wolves. Interestingly, having experienced livestock losses had a minor impact on perceptions of the carnivores. Occupation of the respondents had a strong effect on perceptions of snow leopards but not of wolves. Literacy and age had weak impacts on snow leopard perceptions, but the interaction among these terms showed a marked effect, that is, being illiterate had a more marked negative impact among older respondents. Among the various factors affecting perceptions of wolves, numbers of livestock owned and gender were the most important predictors. People with larger livestock herds were more negative towards wolves. In terms of gender, males were more positive to wolves than females, but no such pattern was observed for snow leopards. People’s negative perceptions towards wolves were also related to the remoteness of the villages. Factors affecting people’s perceptions could not be generalized for the two species, and thus need to be addressed separately. We suggest future conservation projects and programs should prioritize remote settlements.

In Asia, carnivore conservation is often focused on charismatic big cats. Opportunities to conserve the entire carnivore guild are frequently overlooked by channeling conservation and mitigation efforts into single‐species conservation. We synthesize experiences across Asia to explore these challenges and propose mitigations to maximize conservation benefits for the entire carnivore guild. Seven challenges for wolves (Canis lupus) in Asia are highlighted: wolves (1) have been neglected over decades of single‐species conservation, (2) receive less cultural appreciation in many regions, (3) are subject to lax legislation and law enforcement, (4) are often blamed disproportionately for livestock depredation, (5) are often considered more abundant than they are, (6), receive disproportionately little attention from the scientific and conservation communities relative to their ecological importance, and (7) are threatened ecologically and genetically by increasing feral dog populations. As a result, the status of wolves across Asia is poorly documented, there is an enhanced risk of losing significant evolutionary lineages, and it detracts from research and conservation opportunities to preserve the entire carnivore guild. We propose various remedies, such as widening the scope of existing conservation programs, building awareness and knowledge of communities and law enforcement agencies, and more research to inform conservation and legislation.

Maintaining a healthy population of common leopards, a highly adaptive felid, requires updated information on their spatial occurrence. In Nepal's Tarai region, leopards coexist with tigers, which are well‐studied felid throughout its range. However, knowledge is very scarce on the patterns of leopard occupancy. We conducted an occupancy survey using remote cameras in southwestern Tarai, particularly in Shuklaphanta National Park, Nepal, to assess habitat use by leopards from December 2022 to January 2023. Naive and model‐averaged occupancy estimates were 0.51 and 0.6563 (SE: 0.022, 95% CI: 0.612, 0.70), respectively. The detection of leopards was negatively correlated with the presence of tigers. Leopard occupancy was higher closer to human settlement and higher in rugged terrain. At a time when Nepal has achieved its tiger conservation targets, efforts are required to maintain adequate prey biomass to minimize fatal encounters between tigers and leopards and displacement of leopards peripheral to the settlement area, where villagers might kill them in retaliation of livestock killing. Long‐term monitoring is required to improve understanding of the interaction between leopards, tigers, and humans in the Tarai region of Nepal.

Human–wildlife conflict studies of high‐altitude areas are rare due to budget constraints and the challenging nature of research in these remote environments. This study investigates the prevalence and increasing trend of human–wildlife conflict (HWC) in the mountainous Gaurishankar Conservation Area (GCA) of Nepal, with a specific focus on leopard (Panthera pardus) and Himalayan black bear (Ursus thibetanus laniger). The study analyzes a decade of HWC reports and identifies goats as the livestock most targeted by leopards. The Dolakha district of GCA received the highest number of reports, highlighting the need for mitigation measures in the area. In GCA, livestock attacks accounted for 85% of compensation, with the remaining 15% for human injuries. We estimate that the number of reported wildlife attacks grew on average by 33% per year, with an additional increase of 57 reports per year following the implementation of a new compensation policy during BS 2076 (2019 AD). While bear attacks showed no significant change post‐rule alteration, leopard attack reports surged from 1 to 60 annually, indicating improved compensation may have resulted in increased leopard‐attack reporting rates. The findings emphasize the economic impact of HWC on local communities and suggest strategies such as increasing prey populations, promoting community education and awareness, enhancing alternative livelihood options, developing community‐based insurance programs, and implementing secure enclosures (corrals) to minimize conflicts and foster harmonious coexistence. This research addresses a knowledge gap in HWC in high‐altitude conservation areas like the GCA, providing valuable insights for conservation stakeholders and contributing to biodiversity conservation and the well‐being of humans and wildlife. Recent policy changes have reduced hurdles to receiving compensation for wildlife attacks on people and livestock within the mountainous Gaurishankar Conservation Area of the Himalayas. We show that over the last decade, the number of reported attacks have increased by approximately 33% per year, after accounting for the boost in reporting due to improved compensation. The reported number of injuries by Himalayan black bears was overshadowed by a rise in reports of leopard predation on livestock, particularly goats, an important source of income for local farmers.

There are two main international strategies concerning how to ensure a sustainable environment: one is to develop a globally bio-based economy, or bioeconomy, to meet the increased demand of goods and products to maintain our well-being and to reduce climate change. On the other hand, there is an aim to decrease the negative impacts on nature and natural habitats to conserve and maintain ecosystems and control the loss of biodiversity. There is a trade-off between these two strategies; as we increase the commitment to the bioeconomy by intensifying biomass production, we will simultaneously challenge biodiversity through the increased pressure on, and the utilization of, biological raw materials. Here, we first review and discuss the challenges and opportunities in terrestrial and marine ecosystems for the production of biomass for the bioeconomy. We focus on the trade-offs between economic sustainability on one hand, and environmental sustainability and resilience on the other hand. We conclude with a discussion of the various bioeconomy strategies. Finally, we present a conceptual model on how to sustainably develop the bioeconomies (by introducing the concept of optimizing the economic gain/ecological pain ratio) to be able to manage the biodiversity in a sustainable way.

The taxonomic status of the wolf (Canis lupus) in Nepal's Trans-Himalaya is poorly understood. Recent genetic studies have revealed the existence of three lineages of wolves in the Indian sub-continent. Of these, the Himalayan wolf, Canis lupus chanco, has been reported to be the most ancient lineage historically distributed within the Nepal Himalaya. These wolves residing in the Trans-Himalayan region have been suggested to be smaller and very different from the European wolf. During October 2011, six fecal samples suspected to have originated from wolves were collected from Upper Mustang in the Annapurna Conservation Area of Nepal. DNA extraction and amplification of the mitochondrial (mt) control region (CR) locus yielded sequences from five out of six samples. One sample matched domestic dog sequences in GenBank, while the remaining four samples were aligned within the monophyletic and ancient Himalayan wolf clade. These four sequences which matched each other, were new and represented a novel Himalayan wolf haplotype. This result confirms that the endangered ancient Himalayan wolf is extant in Nepal. Detailed genomic study covering Nepal's entire Himalayan landscape is recommended in order to understand their distribution, taxonomy and, genetic relatedness with other wolves potentially sharing the same landscape.
