Spatial decomposition of predation risk using resource selection functions: An example in a wolf-elk predator-prey system
Article Abstract:
A study is conducted which shows how predation risk can be decomposed into encounter and attack stages, and modeled spatially using resource selection functions and resource selection probability functions. It is shown that landscape attributes can render prey more or less susceptible to predation and effects of landscape features can differ between the encounter and attack stages of predation.

Shaping can influence the rate of colony fragmentation in ground nesting seabirds
Article Abstract:
The study shows that since predation and colony contractions are edge related, the initial shape of the colony may play an important role in how quickly it might fragment and in turn how long it might persist. It is shown that fragmentation is likely to occur on the smaller subcolonies and their shape will likely affect the rate of fragmentation.

Safety in numbers for secondary prey populations: an experimental test using egg predation by small mammals in New Zealand
Article Abstract:
The theoretical predictions of an inverse density-dependent relationship between predation risk and the abundance of a secondary prey are investigated. Abundant introduced predators have the potential to drive a small secondary prey population to extinction.
