Seed predation in a Mediterranean pasture: can ants modify the floristic composition of soil seed banks?
(Sociedad de Biología de Chile, 2005)
Impact of Ligustrum lucidum on the soil seed bank in invaded subtropical seasonally dry woodlands (Córdoba, Argentina)
(Springer, 2015-10)
The impact of invasive species on below ground flora may differ from that on the above ground vegetation. Recent reviews of invaded and native communities emphasize the need for more comprehensive information on the impacts ...
Longevity of seeds and soil seed bank of the Cerrado tree Miconia chartacea (Melastomataceae)
(2015-12-01)
Miconia chartacea is a widely distributed tree in Brazil, occurring at altitudes ranging from 300 m to 1900 m in the Caatinga, Cerrado and Atlantic Forest biomes. In this work we attempted to classify M. chartacea seeds ...
Seed rain and soil seed bank compensatory roles on Nassella tenuis (Phil.) Barkworth seedling recruitment in ungrazed and grazed sites
(Science Press, 2022-05)
In semi-arid lands, vegetation is distributed in shrub patches immersed in a less vegetated interpatch matrix. Grazing affects perennial grass seed bank through a decrease in seed rain and an increase in seed predation and ...
Preserving popcorn while boosting livelihoods

Continuous grazing disrupts desert grass-soil seed bank composition under variable rainfall
(Springer, 2021-02)
Long-term field studies help unveil mechanisms of grass soil seed bank (SSB) persistence and resilience. We wonder whether grazing is a disruptive force that changes grass SSB composition and size, while heavy rainfall is ...
The dynamics of three shrub species in a fire-prone temperate savanna: the interplay between the seed bank, seed rain and fire regime
(Springer, 2013-01)
A model was developed to assess how the seed rain and fire regime affect seed bank dynamics and seedling establishment of three native shrub species (Acanthostyles buniifolius, Baccharis pingraea and Baccharis dracunculifolia) ...
Edaphic patchiness influences grassland regeneration from the soil seed bank in mountain grasslands of central Argentina
(Wiley Blackwell Publishing, Inc, 2001-04)
The soil seed- banks in the main natural vegetation patches that makes up mountain grasslands on granite substrates in central Argentina were studied. The main natural vegetation types are moist swards, tall- tussock ...
Importance of the soil seed bank of disturbed sites in Chilean matorral in early secondary succession
(1992)
Abstract. The dynamics of the seed bank may provide clues to the process of recovery of the vegetation of disturbed sites. The role of the seed bank may be more important in areas with a seasonal climate than in areas where ...
Seed survival of the tropical tree cryptocarya aschersoniana (lauraceae): consequences of habitat disturbance
