Grass endophytes in diet protect sibling voles from least weasel predation

Abstract

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
