Summary
# Editorial Summary Understanding dietary preferences and foraging strategies in apex predators is fundamental to conservation planning, particularly in remote ecosystems where livestock coexistence is economically vital to local communities. Chetri and colleagues analysed 182 snow leopard and 57 wolf faecal samples collected across 5,000 km² of the Central Himalayas, using genetic analysis to confirm species identity and prey remains, whilst simultaneously surveying prey abundance across 26 sampling grids to determine actual selection patterns rather than mere availability. Snow leopards demonstrated strong preference for cliff-dwelling wild ungulates—predominantly bharal (57% of identified material)—whilst wolves favoured plain-dwelling species such as Tibetan gazelle and kiang (31%), a divergence that mirrors their respective habitat utilisation; both predators consumed livestock at rates significantly below their proportional availability, though only snow leopards showed statistically significant avoidance behaviour. Sexual dimorphism emerged as a significant variable: male snow leopards consumed substantially more livestock (47% versus 21% in females) and wild ungulates showed inverse patterns, suggesting males pursue higher-risk foraging strategies, a pattern previously documented through telemetry studies. These findings have direct implications for livestock management strategies and compensation schemes in Himalayan communities; interventions should account for sex-specific predation patterns and the predators' demonstrated preference for wild prey, indicating that improving wild ungulate habitat and populations may reduce conflict mortality.

Practical Takeaways
- •Not applicable — this study concerns wildlife ecology of Himalayan carnivores and has no direct relevance to equine practice, farriery, veterinary care, or equine management
Key Findings
- •Snow leopards primarily consumed cliff-dwelling wild ungulates (57% bharal) while wolves preferred plain-dwelling species (31% comprised of Tibetan gazelle, kiang, and argali)
- •Both predators consumed livestock less frequently than availability (snow leopard 27%, wolf 24%), with significant avoidance only in snow leopards
- •Male snow leopards consumed more livestock (47%) than females (21%), while females consumed more wild ungulates (70% vs 48%), suggesting sex-based foraging strategy differences
- •Wolves showed seasonal variation in small mammal/bird consumption linked to marmot hibernation, while snow leopard diet varied by latitude with increased wild ungulates northward
