dc.description.abstractMammals cannot avoid ingesting secondary metabolites, often in significant amounts. Thus, their intake must be regulated to avoid intoxication. Three broad mechanisms have been described by which this can be achieved. These are conditioned aversions mediated by nausea, non-conditioned aversions and the recognition of limits to detoxification. Although there is some overlap between these, we know little about the way that mechanisms of toxin avoidance interact with regulation of nutrient intake and whether one has priority over the other. Nonetheless, regulation of meal length and inter-meal length allows the intake of some plant secondary metabolites to be matched with an animal’s capacity for detoxification and its nutritional requirements. Toxicity itself is not a fixed limitation and recent work suggests that ambient temperature can be a major determinant of the toxicity of plant secondary metabolites, largely through effects on liver function. These effects are likely to be of major importance in predicting the impact of global climate change on herbivores.en_AU
