Title (up) The contingencies of group size and vigilance Type Miscellaneous

Abstract Background: Predation risk declines non-linearly with one's own vigilance and the vigilance of others in the group (the 'many-eyes' effect). Furthermore, as group size increases, the individual's risk of predation may decline through dilution with more potential victims, but may increase if larger groups attract more predators. These are known, respectively, as the dilution effect and the attraction effect.

Assumptions: Feeding animals use vigilance to trade-off food and safety. Net feeding rate declines linearly with vigilance.

Question: How do the many-eyes, dilution, and attraction effects interact to influence the relationship between group size and vigilance behaviour?

Mathematical methods: We use game theory and the fitness-generating function to determine the ESS level of vigilance of an individual within a group.

Predictions: Vigilance decreases with group size as a consequence of the many-eyes and dilution effects but increases with group size as a consequence of the attraction effect, when they act independent of each other. Their synergetic effects on vigilance depend upon the relative strengths of each and their interactions. Regardless, the influence of other factors on vigilance – such as encounter rate with predators, predator lethality, marginal value of energy, and value of vigilance – decline with group size.

Title (up) The WWF Snow Leopard Action Strategy for the Himalayan Region Type Miscellaneous
Year 2006 Publication Abbreviated Journal
Volume Issue Pages 1-21
Keywords behaviour; biodiversity; conservation; ecology; Himalayan; protected area; snow leopard; strategy; Wwf
Abstract As a 'flagship' and 'umbrella' species the snow leopard can be a unifying biological feature to

raise awareness of its plight and the need for conservation, which will benefit other facets of Himalayan

biodiversity as well. Some studies of snow leopards have been conducted in the Himalayan region. But,

because of its elusive nature and preference for remote and inaccessible habitat, knowledge of the

ecology and behaviour of this mystical montane predator is scant. The available information, however,

suggests that snow leopards occur at low densities and large areas of habitat are required to conserve

a viable population. Thus, many researchers and conservationists have advocated landscape-scale

approaches to conservation within a regional context, rather than focusing on individual protected areas.

While the issues are regional, the WWF's in the region have developed 5-year strategic actions and

activities, using the regional strategies as a touchstone, which will be implemented at national levels.

The WWF's will develop proposals based on these strategic actions, with estimated budgets, for use by

the network for funding and fund-raising. WWF also recognizes the need to collaborate and coordinate

within the network and with other organizations in the region to achieve conservation goals in an

efficient manner, and will form a working group to coordinate activities and monitor progress.
