Conditioned taste aversion is an emerging conservation tool that can be used to limit inter-species conflict, for example decreasing predation on endangered species, or limiting the consumption of invasive toxic prey. Typically, managers wish to elicit an aversion that will be associated with visual or odour cues so that the target species maintains an “arm's length” relationship, and does not have to attack or taste the prey. Combining multiple cues in conditioned taste aversion can cause cue overshadowing, so reducing the effectiveness of the training. Here, we examine the northern quoll (Dasyurus hallucatus), a carnivorous marsupial threatened because they attack the toxic invasive cane t..View full abstract
