Climate change and the loss of ecologically relevant large terrestrial carnivore populations are two important challenges currently facing conservation practitioners (Ray et al. 2005, Sutherland et al. 2009). Little attention is given, however, to how these two problems might be related, and how mitigation eff orts for each might be united. Here we explain how predators cannot only infl uence t...

Although this is a reasonable intractability assumption, it would be preferable to base a security proof on a weaker assumption, such as the Computational Diffie-Hellman assumption...
