Variations among plant ontogenetic stages have been found amongst others in leaf toughness [10,17] and chemical defences such as phenolics [18–20]. Boege and Marquis [21] have proposed a pattern for plant ontogenetic [...] tolerance with increasing levels until reaching an optimum as plants further develop. In woody plants, chemical and physical defences increase during seedling and vegetative juvenile stages, respectively, but [...] leaf tissues [59]. Furthermore, phenolic compounds are indicated by C content because mechanical or chemical defences are often carbon-based [60,61]. Despite the absence of differences in plant defences between

can reduce tree growth, but alters material flows from canopies to forest soils. Therefore, the chemical quality of litter is changed (increases in nitrogen content) through enhanced nutrient cycling rates [...] seems to enhance nutrient cycling rates through an increase of nitrogen (N) content that changes the chemical quality of litter (Chapman et al., 2003). Leaf damage is variable between broadleaved temperate [...] can be divided into structural (spines and thorns, trichomes, and toughened or hardened leaves), chemical (defence compounds), and phenological types (e.g. life-history of plants). In conclusion, various

[21–23]. Carbon content is negatively corre- lated to leaf palatability [24] because mechanical or chemical defenses are often carbon-based [25,26]. Also leaf toughness negatively influences palatability [...] growing species produce more carbon-based secondary defense compounds than shade leaves [33,34]. Chemical defenses of woody plants also vary by growth stage, increasing from juveniles to adults [63]. And [...] for F. sylvatica compared to A. pseudoplatanus and C. betulus.
