  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.
