Summary• Leaf physiognomic traits vary predictably along climatic and environmental gradients. The relationships between leaf physiognomy and climate have been investigated on different continents, but so far an investigation based on European vegetation has been missing.• A grid data set (0.5 ° × 0.5 ° latitude/longitude) has been compiled in order to determine spatial patterns of leaf physiognomy across Europe. Based on distribution maps of native European hardwoods, synthetic chorologic flora lists were compiled for all grid cells. Every synthetic chorologic flora was characterised by 25 leaf physiognomic traits and correlated with 16 climatic parameters.• Clear spatial patterns of leaf physiognomy have been observed, which are statistically significant related to certain, temperature-related climate parameters. Transfer functions for several climatic parameters have been established, based on the observed relationships.• The study provides evidence that synthetically generated floras represent a powerful tool for analysing spatial patterns of leaf physiognomy and their relationships to climate. The transfer functions from the European data set indicate slightly different relationships of leaf physiognomy and environment compared with results obtained from other continents.

Vegetation structure will include the following components for the purpose of this lecture:-Texture, the distribution of above-ground biomass, the distribution of sizes (diameter, height) of individuals (shoots) -Stratification, the formation of layers, the vertical distribution of biomass -Pattern, the occurrence of regular, clumped, or random distributions of plant units of different species -Interaction pattern, the occurrence of joint distributions of plant units of different species through positive interactions, or of species exclusions.Dynamics will include: Disturbance, the occurrence of abiotic and biotic events which lead to the disappearance of plant units and the subsequent formation of gaps.Fluctuation, the change in the quantity of strength of one or more environmental factors leading to the disappearance, appearance, and change in quantity of individual plant species.Succession, long-term dynamics leading to directional changes in the composition of plant communities, including their structure.Diversity will include the following components: Species richness, i.e. the number of species on a representative area occupied by a certain plant 'community, or the rate of increase in species number with increasing area (alpha-diversity).Size of basic area, i.e. where one and not more than one species occurs (determines together with alpha the number of species on the representative area).Dominance-diversity relation, i.e. the relative importances of species biomass or cover values.Relations between structure and dynamics include:-Creation of gaps, %ntipatterns'l, through disturbance and the subsequent re-establishment of species, mainly through germination, adapted to the different light and moisture conditions. Grazing and mowing will be considered as special forms of disturbance which usually have a regu1A.r occurrence and do not lead GIORNALE
