Molnár, J., Erdei, B. ; Hably, L.: The transport of leaves and fruits - a taphonomical study of leaf litter

In order to study the relationship between the surface and density (g/cm2) of the leaf lamina and the distance the leaf was transported to, 50-50 intact leaves were taken out in a random way from a quadrat close to the tree (1.5 m) and several others far away from the tree (16.5 m, 1 8 m, 19.5 m, 21 m, 22.5 m). In order to calculate leaf density, the weight of each leaf was measured, its silhouette was cut from paper and the weight of the paper leaf was measured again. The next step was to determine the weight of a piece of paper of 10 cm x 10 cm (0.8244 g). Consequently, the surface of the paper leaf could be measured from its weight (surface [cm 2 ] = 100 [cm 2 ] x weight of the paper leaf [g] / weight of the piece of paper of 100 cm 2 [g]) and then the density of the original leaf could be esti­mated by the help of its weight. The average leaf mass, surface and density of the leaves in the quadrat close to the tree were compared to those of the quadrats situated far away from the tree. The reason for taking out leaves from several distant quadrats and not from one was that number of leaves in these quadrats was relatively low and leaves of statistical quantities could be provided only this way. Weight measurements were carried out by a precision assay balance weighing to the 0.1 mg (Sartorius Handy). For the statistical analyses the Graph Pad Prism 3.00 (San Diego) and Syntax 2000 softwares were used and the values of P < 0.05 were taken as significant. Sample plot II An area covered with relatively closed arborescent vegetation including both angiosperms and gymnosperms was chosen (Fig. 4). Method of sampling - Sampling was carried out twice, in autumn (November 2000) and the subsequent spring (May 2001 ). In the course of the first sampling in autumn quadrats of 0.5 m x 0.5 m Figs 2-3. 2 = Sample plot I with the six transections and position of the taxa investigated. Quadrats of 0.5 m x 0.5 m were set along the transections at each 1.5 m. 3 = Sample plot I showing spatial position of trees
