Contrasting effects of mammal grazing on foliar fungal diseases: patterns and potential mechanisms

Summary Plant pathogens and their hosts often coexist with mammal grazers. However, the direction and strength of grazing effects on foliar fungal diseases can be idiosyncratic, varying among host plant species and pathogen types. We combined a 6 yr yak‐grazing experiment, a clipping experiment simulating different mammal consumption patterns (leaf damage vs whole‐leaf removal), and a meta‐analysis of 63 comparisons to evaluate how grazing...
