soil seed bank ppt

soil or mixed to soil debris constitute the soil seed bank (Simpson et al., 1989). Soil for sampling the seed bank was collected in autumn from an area of ca. However, long-term data on the community dynamics in the seed bank and the standing vegetation are needed to test this prediction. Dormancy helps ensure that seeds only germinate when conditions are right. Synthesis: The effect of the seed bank on the temporal variability of the vegetation in annual communities depends on site conditions and time scale. h�b```�RIMaf`��0p\`j�9�`�� ������{.���� � @��������uG ��b�a�}�,�~ ���cXbW3�3T0hl�u�0�G��'�^.��� -,� ��|R��gOC�� K�$� the soil seed bank of grassland, heathland, and scrub oak sites.
