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>
Holocene climate changes explain the spatial pattern in genetic diversity in populations of Cyperus papyrus from Southeast Africa wetlands
<p>Wetlands are one of the most threatened ecosystems in the world because more than 70% of the area worldwide has been lost since 1900. Wetland plant species rely greatly on water for seeds and propagules, which may lead to a downstream unidirectional dispersal and accumulation of genetic diversity downstream. However, several species show no support for unidirectional genetic diversity, revealing the complexity of population dynamics and gene flow in wetlands. Here, we used microsatellite loci to address how the past demographic dynamics shaped the contemporary spatial pattern in genetic diversity and population structure of <em>Cyperus papyrus</em> in wetlands of Southeast Africa. Using spatially explicit analysis and coalescent modelling we found no support for unidirectional dispersal. Instead, we found higher genetic diversity in populations upstream than downstream in the river basin. We also found high admixture among populations, most likely due to connections between adjacent river basins during sporadic floods, and ongoing gene flow due to bird-mediated seed dispersal. Our results suggest stepping-stone migration due to strong isolation-by-distance, but not necessarily unidirectional. Moreover, the past demographic dynamics in the Holocene shaped the current pattern of genetic diversity and structure, leading to higher genetic diversity in populations upstream of the Zambezi river basin. Our results also point to the very low genetic diversity of <em>C</em>. <em>papyrus</em> populations in Southeast Africa and the need for management and conservation strategies to guarantee the long-term persistence of the species in the region.</p>
