Seed dispersal distance is more strongly correlated with plant height than with seed mass
TLDR
The first large-scale, cross-species quantification of the correlations between dispersal distance and both seed mass and plant height is provided, enhancing the understanding of plant life-history strategies and improving the ability to predict which species are best at colonizing new environments.

Predicting patterns of post-fire germination in 35 eastern Australian Fabaceae
TLDR
Germination in 35 species from 15 legume genera of southeastern Australia was promoted by a heat treatment which broke the seed coat caused dormancy, and predicted germination levels after a moderate intensity fire should far exceed those after a low intensity fire.

Soil Temperatures During Experimental Bushfires in Relation to Fire Intensity: Consequences for Legume Germination and Fire Management in South-Eastern Australia
TLDR
Prescribed fires with maximum potential for germination will be close to, or in excess of, the limit for control unless the rate of spread is very low, thereby imposing constraints on the use of prescribed fire to achieve both protection and conservation objectives.

How much seed remains in the soil after a fire?
Soil seed banks that persist after a fire are important in fire-prone habitats as they minimise the risk of decline or local extinction in plants, should the fire-free interval be less than the…

Soil temperatures after the passage of a fire : Do they influence the germination of buried seeds ?
Soil temperatures down to a depth of 5 cm were measured in the days following one fire in summer, one fire in winter and in unburnt vegetation during summer. Soil temperatures did not rise above 40°C…

Temperature thresholds of physically dormant seeds and plant functional response to fire: variation among species and relative impact of climate change
TLDR
Evidence from this study supports including dormancy-breaking temperature thresholds as an attribute for identifying functional types in trait frameworks, and predicts that species in the facultative group are most at risk to increased seed bank decay resulting from elevated soil temperatures under projected climate change.

Population dynamics of the shrub Acacia suaveolens (Sm.) Willd.: Dispersal and the dynamics of the soil seed‐bank
  • T. Auld
  • Environmental Science
  • 1 September 1986
TLDR
The dynamics of various components of the soil seed-bank were examined using seeds buried in nylon mesh containers, enabling a population to persist as seeds after all above-ground plants have perished.

Climate change and bet‐hedging: interactions between increased soil temperatures and seed bank persistence
In order to predict the long‐term consequences of climate change, it is necessary to link future environmental changes to mechanisms that control plant population processes. This information can then…

Patterns in longevity of soil seedbanks in fire-prone communities of south-eastern Australia.
TLDR
Examination of seed longevity patterns in 12 shrub and two graminoid species in fire-prone habitats around Sydney, south-eastern Australia found that maintenance of a soil seedbank is predicted to be dependent on continual inputs of seeds locally or dispersal of seeds from other sites.

Interactive effects of heat shock and smoke on germination of nine species forming soil seed banks within the Sydney region
TLDR
Germination of one species, Baeckea imbricata, was only stimulated by a specific combination of cues, indicating that regeneration niches may be narrow for some species and that the application of a range of heat and smoke doses is required to find such responses.
