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

Seed rain and soil seed banks in Chinese fir plantations and an adjacent natural forest
<p>The natural regeneration of native broadleaved species underneath forest monoculture plantations is important to recover ecosystem functions and to mitigate adverse environmental effects. To understand how seed rain and soil seed banks facilitate natural regeneration, we surveyed their density and composition in a monoculture Chinese fir plantation, a mixed Chinese fir–broadleaf plantation, and an adjacent natural broadleaved forest for two years in southern China. Twenty-eight species (16 families) were in seed rain, and 45 species (27 families) were in soil seed banks. Seed rain density did not differ significantly across stands; however, the number of taxa in seed rain was highest in the mixed plantation and lowest in the natural forest. Seed bank density was significantly higher in the mixed plantation than in the other stands. The Sørensen similarity indices of species composition between seed sources and aboveground vegetation were relatively low (<0.50). In addition, the seeds of native tree species common to the seed banks of the three forests indicated the adjacent natural forest was a seed source for the natural regeneration of native species in forest plantations. To augment regeneration and accelerate the rate of conversion, we recommend direct seeding or planting of desired species.</p>
