| Plant-associated micro-organisms such as mycotoxin-producing endophytes commonly have direct negative effects on herbivores. These effects may be carried over to natural enemies of the herbivores, but this has been rarely explored. We examined how feeding on Neotyphodium endophyte infected (E+) and endophyte free (E−) meadow ryegrass (Scherodonus pratensis) affects body mass, population size and mobility of sibling voles (Microtus levis), and whether the diet mediates the vulnerability of voles to least weasel (Mustela nivalis nivalis) predation. Because least weasels are known to be olfactory hunters, we also examined whether they are able to distinguish olfactory cues of voles fed on E+ and E− diets. Neither body mass of voles nor population size... |

| In this study, we first examined how feeding on Neotyphodium endophyte infected (E+) or endophyte free (E-) meadow ryegrass (Scherodonus pratensis) affects body mass and reproduction of sibling voles (Microtus levis), and then whether diet mediates the vulnerability of voles to least weasel (Mustela nivalis nivalis) predation. |
