“…Overall, the Lerma marshes have diverse seed banks (61 species), and they are abundant (27 000±4 000seeds/m 2 on average). Individually, species richness and the density per square meter of seeds from each marsh are within the range reported for freshwater wetlands of North America (van der Valk & Davis, 1976, 1978Leck & Graveline, 1979;Leck & Simpson, 1987) or elsewhere (Gordon, 2000;Lui et al, 2005;Liu, Zhang, & Lui, 2009;Aponte, Kazakis, Ghosn, & Papanastasis, 2010), where there are 23 to 59 species (Leck, 1989) and from 200 (Liu et al, 2009) to 256 000seeds/ m 2 (van der Valk & Davis, 1979). The species richness and average density of seeds found in the marshes differ significantly among them.…”

“…Over 50% of the species found at both depths were more abundant near the surface. This phenomenon has been documented for various environments, especially in water bodies (Leck & Graveline, 1979;van der Valk & Davis, 1979;Leck & Simpson, 1987;Raffaele, 1996;Boedeltje, Baker, & Heerdt, 2003), and has been linked with the ability of seeds to penetrate the soil (Thompson, Band, & Hodgson, 1993), with the greatest effect of the seed rain in the sediment surface (Poschlod & Jackel, 1993), and with the effect of disturbances caused by animals (Bonis & Lepart, 1994). Around the Lerma marshes, livestock and ducks are common; we observed foraging inward of the marshes.…”

Banco de semillas y vegetación establecida en los últimos remanentes de los humedales de la Meseta Central Mexicana: las ciénagas de Lerma. Seed banks play a central role in vegetation dynamics of many wetlands. Therefore, knowledge of seed reservoirs in the soils of aquatic communities should provide useful tools for conservation and restoration efforts. This study was conducted in the Lerma marshes, one of the last remnants of the vast wetlands that were once in the Mexican Central Plateau. The main objective was to determine the composition and abundance of seed bank and its relationship with established vegetation of the three Lerma marshes. In each marsh, we systematically selected 18 to 40 sampling sites. In each site, the composition of vascular plant vegetation was evaluated in two 10m lines perpendicular to the shore. Every 0.5m, we determined the coverage of species by measuring the intercepted length for each plant or group of plants. At each sampling site where we had evaluated the established vegetation, we collected a sample of the top 10cm of sediment; the soil cores were divided into an upper layer (0-5cm) and a lower layer (5-10cm). These samples were used to evaluate the seed bank by the seedling emergence method. All samples were placed in a greenhouse at 20-25ºC and remained flooded for 15 weeks. Forty-nine species were recorded in the vegetation. Chiconahuapan had the richest and most diverse flora and the greatest number of perennial species. A life-forms analysis showed that perennial herbs, especially rooted-emergent hydrophytes, dominated in the three wetlands. Sixty-one species were identified in the total seed bank; Chimaliapan had the most diverse total seed bank, whereas the mean seedling density was higher in Chignahuapan. Only two species of the total seed bank of each marsh had a density greater than 10% of the total, and more than half were uncommon. The upper layer of sediment (0-5cm) contained two times more seeds/m 2 and species per sample than the lower layer (5-10cm), and there was a significant decrease of seed density with depth. The detrended correspondence analysis produced a clear separation between the composition of the seed banks and established vegetation. In general, in each marsh there was less species diversity in the established vegetation than in the seed bank. Dominance by a few species in the seed bank, the presence of opportunistic species, and the low representation of established species in the seed bank suggest wetland degradation and a low probability of regenerating the natural communities from the seed bank. To ensure the permanence of these marshes, their biodiversity, and therefore the environmental services they provide, up to date planning is a must, and efforts to control and monitor hydrology, water quality, and the influence of human activities are suggested.

“…These successional changes, predicted by the available information about the life history types of the species in Eagle Lake, have actually occurred there (see Bishop et al 1979, Currier 1979, van der Valk and Davis 1979 and at other prairie glacial marshes in Iowa (Weller and Spatcher 1965, Weller and Fredrickson 1974, Bishop et al 1979). There are many parallels between the succession at Eagle Lake and at Lake Naivasha as described by Gaudet (1977 The model as presented is qualitative; it only predicts which species will be present, but does not provide any information about their relative abundance.…”

A qualitative model of succession in freshwater wetlands is proposed, based on the life history features of the species involved. Three key life history traits can be used to characterize wetland species: life-span, propagule longevity, and propagule establishment requirements. By combining these three life history traits, 12 basic wetland life history types are recognized. For each life history type, the future state (presence only in the form of propagules in the seed bank, presence as adult plants, or complete absence) of each species type in a wetland can be predicted if environmental conditions change. Most of the information needed to apply this model to a particular wetland can be obtained by an examination of a wetland's seed bank. Several examples of succesion in North American and African wetlands are presented to illustrate the application of the model.

“…They suggested that at depths of 8 to 10 cm, the marsh soil actually prolongs seed longevity. van der Valk and Davis (1979) found viable seeds at a depth of 35 cm in a prairie pothole, and were able to reconstruct the marsh's former vegetation from the depth structure of the seed bank.…”

“…By examining the seed bank of a drained wetland, information on its potential flora, spatial distribution of species, and vegetation history is made available for restoration planning and management (Major and Pyott 1966, van der Valk and Davis 1979, Pederson 1983, Pederson and van der Valk 1985, van der Valk 1985. How important the seed bank will be in revegetating a wetland to be restored depends 1969,1976,1984).…”
