Selective damage to tree-seedlings by bank voles (Clethrionomys glareolus).

abstract：:Herbivore damage often deters pollinator visitation and many invasive plants in North America are pollinator-dependent. This has important implications for the biological control of invasive plants because it means that agents that deter pollinators may have a larger than expected impact on the plant. Yet interactions...
