Did dingo control cause the elimination of kowaris through mesopredator release effects? A response to Wallach and O’Neill (2009)
Wallach & O'Neill (2009) recently suggested that poison baiting for dingoes (Canis lupus dingo and hybrids) caused the localized extinctions of kowaris (Dasyuroides byrnei) through mesopredator release effects. However, in this paper I briefly highlight some weaknesses in their approach to...
