Effects of Water Level on Three Wetlands Soil Seed Banks on the Tibetan Plateau
BACKGROUND Although the effect of water level on germination in soil seed banks has been documented in many ecosystems, the mechanism is not fully understood, and to date no empirical studies on this subject exist. Further, no work has been done on the effect of water level on seed banks of drying and saline-alkaline wetlands in alpine areas on the Tibetan Plateau. METHODOLOGY We examined the...
متن کاملRegenerative role of seed banks following an intense soil disturbance
Our main aim was to determine the contribution of the seed bank to vegetation regeneration following a disturbance consisting in a deep ploughing and a thorough homogenisation of a perennial grassland. In the seed bank prior to disturbance, seed distribution through the vertical soil profile was evaluated to determine the initial seed species structure. Then, several characteristics of the shal...
متن کاملCan Soil Seed Banks Serve as Genetic Memory? A Study of Three Species with Contrasting Life History Strategies
We attempted to confirm that seed banks can be viewed as an important genetic reservoir by testing the hypothesis that standing (aboveground) plants represent a nonrandom sample of the seed bank. We sampled multilocus allozyme genotypes from three species with different life history strategies: Amaranthus retroflexus, Carduus acanthoides, Pastinaca sativa. In four populations of each species we...
متن کاملSoil seed banks in four 22-year-old plantations in South China: Implications for restoration
To better understand the potentials of the soil seed banks in facilitating succession towards a more natural forest of native tree species, we quantified the size and composition of the soil seed banks in established plantations in South China. The seed banks were from four typical 22-year-old plantations, i.e., legume, mixed-conifer, mixed-native, and Eucalyptus overstory species. Species dive...
متن کاملThe Unimodal (Species Richness-Biomass) Relationship in Microcommunities Emerging from Soil Seed Banks
We propose using plant microcommunities emerging from soil seed banks as experimental systems for studing species richness. We gathered soil from four Oklahoma terrestrial habitats, kept the soil moist in pots in a greenhouse, and allowed plants to germinate and interact under different conditions. Although heterogeneity among samples was minimized, we observed the often-reported unimodal relat...
