Seed bank dynamics in tall-tussock grasslands along an altitudinal gradient
(Wiley Blackwell Publishing, Inc, 2003-02)
We studied the germinable soil seed bank of tall-tussock grasslands along an altitudinal gradient in the mountains of central Argentina. We selected 10 sampling plots at three altitudinal levels (1200 m, 1600 m and 2200 ...
The dynamics of three shrub species in a fire-prone temperate savanna: the interplay between the seed bank, seed rain and fire regime.
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) ...
Noah’s arks in the XXI century. A typology of seed banks
In recent decades, seed banks have spread out worldwide as essential institutions for biodiversity preservation, like new Noah?s arks. However, little is known about the diversity of practices that are involved in them.The ...
Soil seed banks in tropical forest fragments with different disturbance histories in southeastern Brazil
Soil seed banks are considered an important mechanism for natural regeneration in tropical forest ecosystems. This paper investigated the soil seed bank in two semideciduous seasonal tropical forest fragments with different ...
Impact of Ligustrum lucidum on the soil seed bank in invaded subtropical seasonally dry woodlands (Córdoba, Argentina)
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 ...
Seed predation in a Mediterranean pasture: can ants modify the floristic composition of soil seed banks?

Longevity of seeds and soil seed bank of the Cerrado tree Miconia chartacea (Melastomataceae)
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 ...
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 ...
