Rufaut, C. G., & Gibbs, G. W. (2003). Responses of a Tree Weta Population (Hemideina crassidens) After Eradication of the Polynesian Rat from a New Zealand Island. Restoration Ecology, 11(1), 13-19. (3 copies)

• Measures changes in a population of tree weta on an offshore island after removal of rats. 
• Found that weta density didn’t change, but proportion of adults changed, and weta spent more time closer to the ground and less time in tree refuges. 
• The study concludes that weta are able to withstand rat predation, but live a more relaxed lifestyle in their absence.
