“…Flooding affects the composition and distribution of soil seed banks through three pathways (Peterson and Baldwin 2004;James et al 2007;Nielsen et al 2012). The first is that flooding differentiates the exposed season and duration of a riverbank, which further differentiates the riverbank in the rainy season and the timeline along the altitude gradient (Weiterova 2008;Wang et al 2013). The second is that flooding causes seeds to disperse, and some seeds that land on the soil surface move with the water flow (Thompson et al 2014).…”

The reverse seasonal flooding that resulted from the construction of the Three Gorges Project has induced a drastic degradation of draw-down zone vegetation and the seed bank in the reservoir. The composition and distribution of seed banks and their similarities to standing vegetation were determined through field investigations and germination experiments on the vegetation as well as soil seed bank data collected from three restoration sites in Zigui county, Wanzhou city, and Zhongxian county to uncover the effects of vegetation restoration on seed bank development in the Three Gorges Reservoir region. The results showed the soil seed banks were composed of 44, 43, and 50 herbaceous species, and an average seed density of 9418.79 ± 804.92, 4283.44 ± 427.89, 6539.28 ± 432.22 seeds/m 2 , respectively. The soil seed bank was mainly composed of annual and perennial herbaceous plants. Most of the dominant species of soil seed banks came from introduced species. Reverse seasonal flooding induced the spatial variation of species diversity and seed density of the soil seed bank. The species diversity in the upper part of the draw-down zone was higher than that in the middle and lower parts. The highest seed density occurred in the middle upper parts of the drawdown zone, followed by the lower part. The similarity coefficient between the soil seed bank and the extant vegetation community was 0.495, 0.526, and 0.550 at Zigui, Wanzhou, and Zhongxian restoration sites, respectively.

“…In our material none of the woody species found in the vegetation at our sites were germinating from the seed banks in agreement with this general statement. Seed weight has been found to be related to occurrence in soil seed banks (Wang et al 2013, Jaganathan et al 2015. Light seeds occur more often in soil seed banks (Funes et al 2007, Saatkamp et al 2014.…”

Seed dispersal is a key process in plant community dynamics, and soil seed banks represent seed dispersal in time rather than in space. Despite their potential importance, seed bank dynamics in the Arctic are poorly understood. We investigated soil seed banks and corresponding plant community composition in three contrasting vegetation types in West Greenland, viz. dwarf shrub heaths, herb slopes and fell-fields. Through germination testing, 31 species were documented in soil seed banks. All of these were herbaceous, while no dwarf-shrub species, which represents the dominating growth form in the above-ground vegetation, were emerging from the seed bank. Consequently, across vegetation types, the lowest similarity between seed bank and above-ground vegetation was found in dwarf shrub heath. Nine plant species were exclusively found in seed bank, all of which were non-clonal forbs. Seed bank size (total number of seeds) and species richness seemed to increase with the level of natural disturbance. Additionally, we examined the effect of different experimental light and temperature conditions on the quantity and diversity of germinating seeds. The difference in diversity in vegetation and seed bank at the species level will impact population dynamics, regeneration of vegetation after disturbances and its potential to respond to climate change.

“…However, the influence of spatial and temporal heterogeneity on the soil seed bank of areas that have undergone the removal of vegetation is still poorly documented, making it difficult to assess the potential for restoration of anthropogenic forests, the resilience of which, among other factors, depends on the availability of seeds from the soil bank for recruitment (Baeten et al, 2009;Lopes et al, 2012;Wang et al, 2013).…”

Abstract:Seed banks play an important role in the resilience of potential anthropogenic areas and are influenced by seasonal variation. The spatial and temporal heterogeneity of the forests influences the richness and density of the soil seed bank, but there is a hypothesis that such influence can be changed in anthropogenic areas, where we expect to find lower richness and seed density in relation to the seed bank of mature forests. The richness and seasonal density of seeds in the soil depth of a young caatinga forest, 17 years after an agricultural activity was abandoned, were evaluated and compared with those of a mature forest. The study was conducted at the Instituto Agronômico de Pernambuco -IPA (Estação Experimental José Nilson de Melo), located in Caruaru, Pernambuco, Brazil, in an area of tropical dry forest, known locally as "caatinga". The local climate is seasonal, the dry season occurring from September to February and the rainy season concentrated in the remaining months. The average annual rainfall over time (time series of 30 years) is 692mm. In each climatic season (rainy and dry), the seed bank was sampled in 210 20x20cm plots (105 in the leaf litter and 105 at 5cm soil depth). The richness and seed density of the soil samples were evaluated by the method of seedling emergence. The seed bank had 47 species, with a predominance of herbaceous plants. Seasonal variation in richness and seed density in the soil (leaf litter + soil) was not significant, but 42 species of the mature forest were absent from the seed bank of the young forest, despite 17 years of natural regeneration and its proximity to the mature forest. On its own, the soil has greater richness and density of seeds than the leaf litter. The depth of seed deposition in the soil bank of the young forest significantly explained 36% of the species richness and 16% of the seed density, with a significant interaction effect with the climatic season only on species richness, explaining 4% of the variation recorded. The seed density of the young forest (1 277seeds/m 2 ) was greater than that the mature forest indicating that the time abandoned had not yet been sufficient for complete recovery of plant diversity and there is no longer any seed limitation of pioneer species for regeneration of the young forest.
