“…The increased availability of nitrogen accelerated the turnover of this element throughout the system but not its accumulation in perennial organs. Unlike oak species [3,37,41,47,84], beech and other hardwood species do not exhibit differential storage and concentrations of nutrients in the different parts of the tree.…”

-Aboveground biomass, litterfall, leaf weight loss due to decomposition, N return and seasonal leaf N dynamics were studied in the Sierra de la Demanda, Spain, a Mediterranean climatic zone. The forest ecosystem considered was a climax beech (Fagus sylvatica L.) forest. Aboveground biomass was estimated by cutting and weighing seven trees from a beech stand according to diameter classes, recording the categories of trunk, branches and leaves. The results indicate a total biomass of 132.7 Mg ha -1 . The litterfall was 4 682 kg ha -1 yr -1 , although variations from year to year were observed, mostly due to water stress in summer. Greater K (Jenny's constant) and K o (Olson's constant) values were obtained for total litter than for leaves alone. It is possible that the mean soil humidity might not be a limiting factor in the decomposition process and that this effect would be due to the distribution of rainfall rather than to the total amount of precipitation together with elevated temperature and airing of the holorganic soil horizon. The leaf N contents of beeches growing in the Sierra de la Demanda were studied, relating the contents to other structural stand characteristics. For this, N was analysed in shed leaves, in leaf biomass and in leaves decomposing on a test plot in the "Tres Aguas" beech forest. Leaf nitrogen contents were measured over a vegetative cycle in the above beech forest. Finally, leaf nitrogen contents were studied in thirty beech stands in the Sierra de la Demanda located at different altitudes. Annual nitrogen accumulation in leaf biomass was 79.4 kg ha -1 yr -1 , of which 22.9 kg ha -1 yr -1 were returned to the soil substrate through shedding and 2.1 kg ha -1 yr -1 were actually incorporated into the soil. Nitrogen cannot be a limiting factor for the development of the beech stands studied because all of them surpassed the leaf deficiency threshold. Only other factors such as soil texture and structure or silvicultural treatment have a decisive effect on the production of the stand studied. The correlations for leaf nitrogen contents and the structural stand characteristics explored revealed that leaf nitrogen was only slightly correlated with the mean height of the trees at the plot. aboveground biomass / litterfall / weight loss / nitrogen / forest ecosystem Résumé -Dynamique de la matière organique et de l'azote dans une hêtraie de la Sierra de la Demanda (Espagne). La biomasse aérienne, la retombée de litière, la perte de poids de feuilles en décomposition, le retour et la dynamique saisonnière de l'azote des feuilles, ont été estimés dans une hêtraie (Fagus sylvatica L.) de la Sierra de la Demanda, (Espagne). La biomasse a été estimée par coupe et pesée de sept arbres selon la distribution des diamètres. Les poids des troncs, branches et feuilles ont été mesurés. Les résultats indiquent une biomasse totale de 132,27 Mg ha -1 . La chute de litière est de 4 682 kg ha -1 an -1 , cependant on a observé des variations inter-annuelles, principalement dues au stress hydrique esti...

“…macroelement concentration, is used as the response index. Different factors influence the element concentrations of leaves: leaf type and plant age, season, availability of elements in soil, climatic and edaphic conditions (Wentworth and Davison 1987;Folkeson et al 1990;Market 1990;Albert and Pescoller-Tiefenthaler 1992). Therefore, there are great variations among element concentrations in different trees.…”

As part of an intensive monitoring programme (MON.I.TO, Intensive Monitoring of Forests in Tuscany), a 3-year survey was carried out, which included three tree species (beech, Fagus sylvatica L.; Turkey oak, Quercus cerris L.; holm-oak, Quercus ilex L.) located at six different sites. Leaves were sampled annually and analysed for nutrient concentrations (nitrogen, sulphur, phosphorus, magnesium, calcium, potassium and sodium) and morphological parameters (leaf area, dry weight, leaf mass per area, leaf thickness and leaf density). Results indicated considerable interannual variation of all the parameters. Differences between sampling sites indicated that, of all parameters measured, leaf mass per area could explain best the differences in field performance under conditions of stress. In fact, leaf mass per area was greater in the drier sites or when sea salt deposition occurred. Nevertheless, the variation of leaf mass per area over the 3 years did not reflect the differences in rainfall. Higher leaf mass per area was accompanied by lower concentrations of phosphorus and nitrogen, which could be a dilution effect due to an increase of structural carbon compounds in sclerophyllous leaves, as revealed by the total foliar content of these elements. Leaf mass per area as a measure of sclerophylly reached very high values among mesophile vegetation. Long-range transport of sea salt from coastal areas to mountain areas was mirrored in sodium concentrations of leaves.
