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 ...
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 ...
What happens when the rain is back? A hypothetical model on how germination and post-germination occur in a species from transient seed banks
(Public Library Science, 2020-02-26)
We hypothesize that by simulating the natural priming in seeds of a species that forms transient seed banks it is possible to clarify molecular aspects of germination that lead to the recruitment of seedlings when the next ...
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 ...
Seed survival of the tropical tree cryptocarya aschersoniana (lauraceae): consequences of habitat disturbance
(Wiley Online Library, 2017)
Key decision-making criteria for dormancy-breaking and ability to form seed banks of Cerrado native tree species
(Soc Botanica Brasil, 2020-10-01)
Ecological restoration by direct seeding in the Cerrado biome still lacks information about native species germination, the need for dormancy overcoming and seed bank formation. This study aims to verify the effects of ...
Relationship between seed bank expression, adult longevity and aridity in species of Chaetanthera (Asteraceae) in central Chile
(OXFORD UNIV PRESS, 2006-09)
center dot Background and Aims Broad surveys have detected inverse relationships between seed and adult longevity and between seed size and adult longevity. However, low and unpredictable precipitation is also associated ...
A plurality of causal mechanisms explains the persistence or transience of soil seed banks
(Academic Press Ltd - Elsevier Science Ltd, 2010-02)
Annual forbs form short-term persistent soil seed banks whereas perennial grasses form mostly transient ones in the central Monte desert. A conceptual framework predicts that annual forb seeds will have primary dormancy, ...
Natural distribution and phenotypic traits of Neltuma flexuosa var. depressa, a candidate taxon for the rehabilitation in the central arid region of Argentina
(Elsevier, 2023-02)
Dryland rehabilitation in the central arid region of Argentina is urgently needed to reverse the current high levels of degradation. Neltuma flexuosa var. depressa, adapted to arid environments, gives it the potential to ...
