The spatial patterns in the seed bank were examined within a coastal sand-dune system. Soil samples were collected from vegetated and bare plots in three zones, each dominated by different plant species. The total number of seeds and species diversity in the seed bank were low. There were no significant patterns in total seed number. However, there were significant differences in species composition. Seeds of Artemisia campestris (Tall Wormwood) were more abundant in vegetated plots and were found in all zones, although adults are more spatially restricted. Fruits of Cyperus grayii (Gray's Sedge) were most common where adults are found. Dominant species from the site were absent from the seed bank. Overall, composition of the seed bank does not reflect composition of the adult community.

    Fens in Central Europe are characterised by waterlogged organic substrate and low productivity. Human-induced changes due to drainage and mowing lead to changes in plant species composition from natural fen communities to fen meadows and later to over-drained, degraded meadows. Moderate drainage...

    Agriophyllum squarrosum Moq. is a dominant annual on sand dunes in the arid regions of central Asia. A high percentage of seeds is retained on dead plants which become covered by moving sand, but little is known about the ecological significance of burial of canopy-stored seeds. We investigated...
