Leaf damage (%) of beech trees in the three study regions.

<p>Schorfheide (SCH), Hainich (HAI) and Schwäbische Alb (ALB)—in the surveys in May (a) and July 2013 (b) and November 2012 (c). The letters indicate significant differences between regions (ANOVA, Tukey’s post hoc <i>p</i> < 0.05).</p

Influence of beech dominance and harvest intensity on leaf damage (residuals) of beech trees.

<p>Data were collected in May (a,b), July (c,d) and November (e,f) in the three regions Schorfheide (SCH), Hainich (HAI) and Schwäbische Alb (ALB).</p

Relationship between average leaf damage and the total density of herbivore groups.

<p>Spearman rank correlation; data were obtained in May and July and across all sites (<i>n</i> = 48). The correlation between <i>Rhynchaenus fagi</i> (<i>R</i>. <i>fagi</i>) and leaf damage was restricted to the study region ALB (<i>n</i> = 16). Significance levels: ns (not significant),</p><p>* (<i>p</i> < 0.05), and</p><p>*** (<i>p</i> < 0.001).</p><p>Relationship between average leaf damage and the total density of herbivore groups.</p
