“…The importance of seed banking in forest herbs is generally dismissed. However, multiple independent studies have demonstrated seed banking to be more common than hitherto thought (Warr et al, 1994;HilleRisLambers et al, 2005;Kaeser & Kirkman, 2012;. Despite low seed bank density, low seed survival rates and short-term persistence (Kaeser & Kirkman, 2012), seed banks still substantially enhance seedling recruitment in any given year (HilleRisLambers et al, 2005).…”

“…However, multiple independent studies have demonstrated seed banking to be more common than hitherto thought (Warr et al, 1994;HilleRisLambers et al, 2005;Kaeser & Kirkman, 2012;. Despite low seed bank density, low seed survival rates and short-term persistence (Kaeser & Kirkman, 2012), seed banks still substantially enhance seedling recruitment in any given year (HilleRisLambers et al, 2005). Specifically in a temporally and spatially heterogeneous forest environment, seed banks enable forest species to capitalize on rare temporally unpredictable opportunities for successful recruitment, notably when seed production is low (HilleRisLambers et al, 2005).…”

Aim: Seed banks are central to the regeneration strategy of many plant species. Any factor altering seed bank density thus affects plant regeneration and population dynamics. Although seed banks are dynamic entities controlled by multiple environmental drivers, climatic factors are the most comprehensive, but still poorly understood. This study investigates how climatic variation structures seed production and resulting seed bank patterns. Location: Temperate forests along a 1900km latitudinal gradient in north-western (NW) Europe. Methods: Seed production and seed bank density were quantified in 153 plots along the gradient for four forest herbs with different seed longevity: Geum urbanum, Milium effusum, Poa nemoralis and Stachys sylvatica. We tested the importance of climatic and local environmental factors in shaping seed production and seed bank density. Results: Seed production was determined by population size, and not by climatic factors. G.urbanum and M.effusum seed bank density declined with decreasing temperature (growing degree days) and/or increasing temperature range (maximum-minimum temperature). P.nemoralis and S.sylvatica seed bank density were limited by population size and not by climatic variables. Seed bank density was also influenced by other, local environmental factors such as soil pH or light availability. Different seed bank patterns emerged due to differential seed longevities. Species with long-lived seeds maintained constant seed bank densities by counteracting the reduced chance of regular years with high seed production at colder northern latitudes. Main conclusions: Seed bank patterns show clear interspecific variation in response to climate across the distribution range. Not all seed banking species may be as well equipped to buffer climate change via their seed bank, notably in short-term persistent species. Since the buffering capacity of seed banks is key to species persistence, these results provide crucial information to advance climatic change predictions on range shifts, community and biodiversity responses

RESUMOA capacidade que determinadas espécies têm de manter as sementes viáveis por longos períodos no banco de sementes é essencial para a resiliência ambiental, o que é utilizado na restauração florestal. Este trabalho teve como objetivo estudar o comportamento de banco de sementes induzido de P. dubium. A indução do banco de sementes foi feita em fragmento de Floresta Estacional Semidecídual. Foram utilizadas 100 amostras de copos de polietileno, compostas por 25 sementes cada. A cada dois meses, 5 amostras foram retiradas para determinação de: conteúdo de água, viabilidade, porcentagem de emergência de plântulas e porcentagem de predação. As sementes da espécie P. dubium podem permanecer por até 16 meses viáveis enterradas no solo. Esse resultado permite a classificação da espécie como formadora de banco de sementes persistente. A predação de sementes foi o principal fator para que ocorresse a redução do banco de sementes do solo.Palavras-chave: dormência, viabilidade, longevidade. Behavior of Peltophorum dubium ((Spreng.) Taub.) Seeds in a Burial Seed Bank ABSTRACTThe ability of certain species in keeping the seeds viable for long periods in the soil seed bank is essential for environmental resilience, which is used in forest restoration. This work aimed to study the behavior of a buried seed bank of P. dubium. Burial seed bank was performed in a fragment of Seasonal Semideciduous Forest. One hundred samples consisting of 25 seeds in polyethylene cups were placed under the canopy. Every two months, five samples were taken for determination of water content, viability, emergency (root protrusion and seedling formation) and predation. Seeds of P. dubium may remain buried in the ground for up to 16 months keeping their viability. This result indicates that P. dubium is able to form persistent soil seed bank. The predation was the main factor contributing to the seed bank reduction.

“…But the greater challenge to total elimination of a weed population for most of the targeted species is the presence of a persistent soil seed bank. Some of these weeds, especially those in the pea family (Fabaceae), have long-lived seeds that can lie dormant in the soil for many years until favorable conditions trigger their germination (Bossard et al 2000, Coffey and Kirkman 2006, DiTomaso and Healy 2007, Kaeser and Kirkman 2012. Blackwood acacia, French broom, and plume acacia are fabaceous weeds that we are aiming to eradicate on SCI.…”
