“…Soil seed banks can contribute to local population persistence and biodiversity maintenance through temporal storage effects (Faist et al, 2013; Plue, De Frenne, et al, 2017), remnant populations (Eriksson, 1996; Plue et al, 2008) and the maintenance of a functional diverse below‐ground species pool available for germination in response to environmental variability or change (Del Cacho & Lloret, 2012; Vandvik et al, 2016). The study of the realised soil seed bank (i.e., the seedlings assemblage emerging under field conditions) is especially important as it can provide very different results from greenhouse experiments (i.e., potential soil seed bank), which often favour light‐demanding species (Panufnik‐Mędrzycka & Kwiatkowska‐Falińska, 2014).…”

AimThe soil seed bank is a key component of the biodiversity of plant communities, but various aspects of its functioning in temperate forest ecosystems are still unknown. We here adopted a trait‐based approach to investigate the effects of macro‐ and microclimatic gradients on the juvenile plant communities from the realized seed bank of two types of European temperate forest.LocationOak‐dominated forests in Italy and Belgium.MethodsWe analysed the variation of key functional traits (plant height, leaf area, leaf dry weight, specific leaf area and leaf number) of juvenile plants from the realised soil seed bank in relation to elevation (from 0 to 800 m a.s.l.), forest type (thinned and unthinned forest) and distance to the forest edge. We translocated soil samples from the forest core to the edge (and vice versa) and from high‐ to low‐elevation forests to test the effects of edge and warming respectively.ResultsTaller communities developed at the forest edge due to higher light availability and warmer temperatures. The translocation from the core to the edge did not significantly modify mean trait values. Instead, the shadier and cooler microclimate of the forest core reduced the mean leaf area, mean dry weight, height and leaf number in the communities realised from the edge soil. The translocation from high‐ to lowland forests led to increased values for all traits (except specific leaf area). Edge vs core trait variation was more driven by intraspecific variability, whereas the translocation from high‐ to low‐elevation forests caused trait changes mostly due to species turnover.ConclusionsGlobal warming might result in a functional shift of the understorey due to both an early filtering effect on the seedlings from soil seed banks and their adaptive trait adjustments to temperature increase. Furthermore, our study underpins the importance of edge vs core microclimate in driving the functional composition of the realised soil seed bank.

“…Greenhouse studies quantify the potential size of a seed bank by making the seeds able to germinate in unlimited light and moisture conditions. However, in natural environments, optimal conditions for germination and growth of seedlings happen sporadically and thus only a few viable seeds have the opportunity to germinate (Panufnik-Medrzycka and Kwiatkowska-Falinska, 2014). The whole number of seedlings emerging in particular ecological conditions in the field informs on the realised size of the seed bank.…”

“…Moreover, most seed bank studies focus on the potential seed bank, meaning to account for all viable seeds in the soil (Bossuyt and Honnay, 2008), regardless of microclimate effects. However, potential and realised seed banks can differ considerably, as shown, for example, by the decrease in lightdemanding species found in the seed bank realised in natural forest conditions compared with that in a greenhouse (Panufnik-Medrzycka and Kwiatkowska-Falinska, 2014).…”

Seed bank responses to different microclimates were studied in temperate forests.• Thermophilous forests showed a compositionally different edge vs interior seed bank. • Forest edges shifted the seedling community to a more light-demanding composition.• Soil translocation from up to lowland favoured the emergence of generalist plants.• Forest fragmentation should be prevented to conserve seed banks' forest specialists.

Long-term variability in seed size and seedling establishment of Maianthemum bifolium

Relatively few studies conducted in natural plants populations focus on the relationship between seed size and their germination ability and seedling establishment. Maianthemum bifolium is a perennial herb that spreads vegetatively through rhizomatous growth and reproduces through seeds. However, this species is characterized as seed and microsite limited, and under undisturbed conditions seedlings are not noted. The studies were conducted in two populations of M. bifolium in six subsequent seasons. The mean seed mass was negatively correlated both per ramet as well as in the fruit with the number of seeds, and positively with its height and the number of flowers. The long-term mean annual production of seeds in the populations was 37 and 56 seeds per m 2 . The seeds from both populations had similarly high germination abilities that were approximately 90% under laboratory conditions, 60% in garden, and 55% in the natural habitat. Seeds from four size classes were sown and a positive correlation was noted between seedling establishment and the mass of the seeds from which they grew (r S = 0.64). Seedling survival was also significantly correlated with seed mass.
