Two Birch Species Demonstrate Opposite Latitudinal Patterns in Infestation by Gall-Making Mites in Northern Europe
Fig 3
Changes in overall proportion of leaves infested by eriophyoid mites (a, b) and in the diversity of gall types (c, d) on Betula pendula (a, c) and B. pubescens (b, d) along latitudinal gradients during 2009–2011. For positions of gradients see Fig 1.
