The effects of agricultural practices on floristic composition of grasslands are well known but few studies investigated these effects on plant spatial patterns involved in the maintenance of plant diversity. In order to identify major processes controlling dispersal patterns of four grassland species, presenting several dispersion modalities (anemochorous, barochorous and zoochorous sensu Grime et al., 1988), we have used spatial analysis (4TLQV and Wavelet)adapted to grids sampling. With these methods, when the quadrat variances are plotted against block size, the peaks of these graphs are interpreted as the scale of the mapped phenomena (Guo and Kelly, 2004). A generalization of mowing impact according to dispersal modalities was highlighted by our... |
