Changes in leaf traits in response to plant–plant interactions affect feeding by insect herbivores. However, the effects of such changes on feeding by vertebrate herbivores remain unclear. We examined the effects of interactions ofAster leiophylluscollected in the field (growing with plants of the same species [aggregated] or with plants of different species [solitary]) or grown in pots (with anotherA. leiophyllus[intraspecific] or withCarex aphanolepisorThalictrum baicalense[interspecific]) on the concentration of total phenolics inA. leiophyllusleaves and on sika deer (Cervus nippon) grazing preference in Japan. Deer were presented for 30 s with the firstA. leiophyllusleaf (from either aggregated plants or solitary plants) and then for 30 s with the second leaf (solitary or aggregated, respectively). All of the deer presented first with a leaf from a solitary plant ate it, but when deer were presented first with a leaf from an aggregated plant, which had a higher concentration of total phenolics, 50% rejected or left it. About a third of the deer that had been presented first with a leaf from an aggregated plant subsequently rejected the leaf of a solitary plant. The leaves in the intraspecific interaction pot treatment had higher total phenolic concentration and were rejected more by deer than the leaves in the interspecific treatments. Plant–plant interactions affected deer preference, which was also influenced by learning. These results should improve our understanding of both plant grazing by deer and environmental management.
