“…Conversely, species represented in the seed bank were almost always present in the above-ground vegetation, as has been found in other studies (Bossuyt & Hermy, 2004;Bossuyt et al, 2005b;Plassmann et al, 2009). Even though there was a positive correlation between perennial herb species richness and perennial herb species density in the seed bank and vegetation, the overall dissimilarity appeared to be driven by perennial species.…”

“…This latter result is the most commonly reported (e.g. Bekker, Lammerts, Schutter & Grootjans, 1999;Bossuyt & Hermy, 2004;Plassmann et al, 2009), in part because of the focus of studies on fixed dune areas.…”

“…Bossuyt & Hermy, 2004;Plassmann, Brown, Jones & Edward-Jones, 2009). However, the low density of seeds found in some studies may result from insufficient cold stratification of the seed bank before assessment by the emergence method (Leicht-Young et al, 2009;Plassmann et al, 2009), or the use of a greenhouse with fixed photoperiod and temperature, which may not provide the temperature fluctuations required to trigger germination in some species. As a result of the large increase in species found combining emergence and seed extraction methods, we recommend that in studies where assessment using seasonal conditions or long-term monitoring of emergence isn't possible, additional seed extraction may improve estimation of seed bank composition and density.…”

“…Annuals species have also been found to dominate seed banks in Mediterranean salt-marsh habitats (Marañón, 1998). Annual herbs produce large quantities of seeds, which often have a high longevity index (Plassmann et al, 2009), a capacity for fast dispersal (Bossuyt & Hermy, 2004;Thompson, 1987), and allocate a higher fraction of their resources to seeds than their perennial counterparts (Thompson, Band & Hodgson, 1993).…”

Degradation of semi-arid ecosystems leading to desertification presents a global environmental challenge. However, few studies have investigated seed bank and above-ground species composition in degraded semiarid dune systems, particularly in relation to their potential to contribute to stabilisation and revegetation. We determined whether soil seed bank and above-ground species composition differed along a chronosequence in the inter-dune lowlands of an active dune field in Inner Mongolia, China. Soil cores were collected in early April 2011 and soil seed bank composition determined using a combination of the seedling emergence and seed extraction methods. Established vegetation, including species composition and abundance, was also surveyed. Relative importance values for all above-ground species and similarities in species composition of vegetation and soil seed bank along the chronosequence were analysed. A clear successional trend was shown for established vegetation along the first three stages identified, followed by a final stage reverting to more mobile substrate due to disturbance by dune movement. This trend was not reflected in the seed bank. Plant and seed bank density increased over time, however, species composition of the seed bank reflected earlier stages rather than the corresponding established vegetation. There was a relationship between established vegetation and the soil seed bank at the earliest stage, driven mainly by the persistence of seeds of the pioneer species Agriophyllum squarrosum and Corispermum candelabrum. A relatively close relationship was also found at the final stage, where frequent disturbance occurred as a result of increasing sand burial, caused by constant directional sand dune movement. While a clear relationship between the seed bank and associated vegetation was not found along the whole chronosequence, the seed bank displayed potential for restoration of pioneer psammophytes and annual herb species, suggesting that it would contribute to regeneration, as well as support latter-stage annuals and several rare and endemic species.

“…The soil seed bank can contribute to plant community dynamics following disturbance (Plassmann et al 2009), but the low species compositional similarity between soil seed bank and aboveground vegetation in type LDT suggests that restoration of degraded sites cannot rely only on soil seed banks (Bossuyt and Honnay 2008). DCA analysis showed that the seed bank flora of SAD and LDT types were relatively similar and differed from that of the C type.…”

Heydari M, Pothier D, Faramarzi M, Merzaei J. 2014. Short-term abandonment of human disturbances in Zagros Oak forest ecosystems: Effects on secondary succession of soil seed . Zagros Oak forests in the west of Iran have been degraded by anthropogenic activities during many years and to fight against this degradation, several management strategies have been implemented. The principal objectives this study were to identify the characteristics of the soil seed bank and the aboveground vegetation that were affected by degradation and short-term abandonment of human disturbances and evaluate the potential of the soil seed bank to restore the degraded types after short-term conservation management. For that, we compared three types of Zagros forest ecosystem with different management regimes: (i) Long term disturbed type as LDT (also used and disturbed at the present), (ii) Short-term abandonment of human disturbances as SAD (5 years without human disturbances) and an undisturbed control or C (iii). We selected three replicates or stands per type. In the aboveground vegetation (ABV), 115, 72 and 51 species were recorded in C, SAD and LDT types, respectively, whereas in the soil seed bank (SSB) flora, 33, 19 and 12 plant taxa were observed in C, SAD and LDT types, respectively. The percentage of annuals increased in ABV and decreased in SSB with increasing site degradation with human activities such as animal husbandry in the forest edges. The percentage of perennial and biennial herbs decreased in ABV and increased in SSB with increasing site degradation. The Shannon index of the SSB decreased with increasing site degradation. The average seed density in the SAD type was significantly larger than that of the LDT type. DCA analysis showed that the seed bank flora of SAD and LDT types were relatively similar and differed from that of the C type. This indicates that a full recovery of degraded type in the oak forest ecosystem in the Zagros region cannot be based only on the soil seed bank present at the beginning of the protection period while a more complete recovery may require a longer period of protection.

The coastal wetland is easily invaded by alien species due to locating in the land and sea transitional area. As a potential driving regeneration force, the soil seed bank is vital to the community restoration and species diversity protection. To reveal the long‐term Spartina alterniflora invasion impact on the soil seed banks and regenerated communities, we investigated the seed banks under the different vegetation types (S. alterniflora, Phragmites australis, Scirpus mariqueter, ruderal and unvegetated site) and soil depths (0–5 and 5–10 cm) in the coastal salt marsh wetland, Chongming island, eastern China. The results showed that the soil seed bank richness and species density under different vegetation types were higher than the aboveground vegetation, and those of 0–5 cm seed banks were higher than 5–10 cm, except for the unvegetated site. The species richness and S. alterniflora seed proportion in the seed banks under S. alterniflora communities (S.AS) were lower and larger respectively than those of other sites. The species composition between S.AS and the aboveground communities showed high similarity with aggregation phylogenetic structures in two soil depths. The seed bank variations at 0–5 and 5–10 cm depths were interpreted 3.03% and 2.25% by the aboveground communities, while 4.92% and 5.55% were interpreted by the soil microbial biomass. The SEM model explained 98.1% and 91.8% of the seed banks richness at the 0–5 cm depth and 5–10 cm depth, respectively, and explained 98.8% and 46.1% of the seed banks species density at the 0–5 cm depth and 5–10 cm depth, respectively. The aboveground vegetation biomass and abundance directly affected the 0–5 cm seed banks richness and species density, while its height and biomass only affected the 5–10 cm seed banks species density. The 0–10 cm soil depth microbial biomass indirectly affected the 0–5 cm seed banks richness and species density, while affected the 5–10 cm seed banks richness. Soil physical and chemical properties only indirectly affected the 0–5 cm seed banks species density. The results provided a reference for the ecological evaluation of the impacts of S. alterniflora invasion into the coastal salt marsh wetland of eastern China, and guidance for the protection and restoration of the native plant communities.
