摘要: We studied interactions between microfungi and herbivores sharing a host tree. In series of experiments field observations over 3-year period, we compared phenotypic genetic correlations fungal frequencies performance invertebrate growing on mature half-sib progenies mountain birches (Betula pubescens ssp. czerepanovii) in two environments, forested river valley an adjacent higher-elevation birch woodland. found little support for direct relation herbivore species. Instead, correlations, particularly autumnal moth (Epirrita autumnata) rust fungus (Melampsoridium betulinum), suggest that may be caused by (1) differences plant quality fungi herbivores, or (2) responses to environmental conditions.
