Fire is known to be a major factor in shaping plants and vegetation worldwide. Many plant traits have been described as adaptations for surviving fire, or regenerating after it. However, many of the traits are also advantageous for overcoming other disturbances. The fact that fire in the Mediterranean Basin has been almost exclusively of anthropogenic origin, and thus is of short duration in an evolutionary time scale, cast doubt on the possibility that fire can act as a selective force in the… 
The challenge of plant regeneration after fire in the Mediterranean Basin: scientific gaps in our knowledge on plant strategies and evolution of traits
A summary is given of the knowledge about the limits and potential of plant regeneration mechanisms after fire in the Mediterranean Basin, along with corresponding studies conducted in other parts of the world with similar climatic conditions in order to present the fullest possible picture.
Chapter 6 Post-Fire Management of Serotinous Pine Forests
Fire response of pines was categorized by Keeley and Zedler (1998) according to two different strategies that are generally considered alternatives or complementary: individual survival (fire
Seed provenance and fire-related reproductive traits of Pinus pinaster in central Spain
Disregarded for centuries, Mediterranean pine forests in Spain have been severely affected by human activities including fires and livestock grazing. As a consequence, reforestation programs were
Repeated Stand-Replacing Crown Fires Affect Seed Morphology and Germination in Aleppo pine
The results suggest that, at least in the short term, fire recurrence does not constrain the reproduction ability of Aleppo pine and the need for further research to elucidate the mechanisms behind these responses to recurrent fires is highlighted.
Reproduction of postfire Pinus halepensis Mill. stands six years after silvicultural treatments
In this study, silvicultural treatments such as thinning and pruning were carried out 5 years after fire in eleven years old Pinus halepensis forests in SE Spain, showing acceleration in cone and viable seed production in thinned plots, with some differences between sites being recorded.
Plasticity of fire related traits of some obligate seeder species in different fire-prone areas of SE France: the goals and methodology used
Species having traits adapted to a given fire regime can be endangered when the fire regime changes if these traits do not vary at the same time, especially with the increase in fire recurrence
Tree density and site quality influence on Pinus halepensis Mill. reproductive characteristics after large fires
In Spain, many Pinus halepensis Mill. forests have been seriously affected by significant forest fires in the past decade, in 1994 alone, more than 100 000 ha were burned in Eastern Spain. In order
Contrasting Effects of Fire Severity on the Regeneration of Pinus halepensis Mill. and Resprouter Species in Recently Thinned Thickets
The results show a positive relationship between forest basal area and fire severity, and thus reserved pines in thinned stands suffered less fire damage than those in un‐thinned sites, and ultimately differences in fire severity influenced post‐fire regeneration.


Reproduction ecology of Pinus halepensis : a monoecious, wind-pollinated and partially serotinous Mediterranean pine tree
It is shown that the dual life strategy complementary rather that competitive optimizes fitness gain under an infrequent fire regime and that seeds from serotinous cones germinate slightly better in the post-fire environment than seeds from non-serotinous cone.
Aleppo Pine (Pinus Halepensis) Postfire Regeneration: the Role of Canopy and Soil Seed Banks
Pinus halepensis (Aleppo pine), is the dominant Introduction tree of a large fraction (26%) of the Greek coniferous forests; this species is an endemic pine of the Mediterra- In Greece, during the
Role of heat tolerance and cone protection of seeds in the response of three pine species to wildfires
The overall scores of seed germination of these three pine species under the conditions tested suggests that their regeneration after fire should come either from the soil bank, or from the canopy bank, but rarely from the ground surface, as the existence of a permanent seed bank in Mediterranean pines is probably limited or nil.
The hypothesis that fire imposes differential selective pressures on serotiny in jack pine is supported by the results of evaluation in populations from two adjacent landscapes in the southern part of the Canadian boreal forest.
Seed dispersal and changing seed characteristics in a Pinus halepensis Mill. forest after fire
The principal component analysis performed on the categorical colour variables produced a good discrimination between seed lots collected at different dates, and the colour of released seeds changed with time: dark grey-brown seeds were released at first, whereas late-dispersed seeds showed a yellowish colour.
Flammability and serotiny as strategies: correlated evolution in pines
It is demonstrated that much variation in trait evolution occurs along a fire-surviving/fire-embracing axis.
Canopy seed banks in Mediterranean pines of south‐eastern Spain: a comparison between Pinus halepensis Mill., P. pinaster Ait., P. nigra Arn. and P. pinea L.
Canopy seed banks were analysed in post-fire stands of Pinus halepensis, P. pinaster, and P. pinea to determine age when flowering begins, age of first cone bearing, presence of serotinous cones and cone-opening temperatures, which suggest early flowering is also necessary for successful post- fire colonization in species or populations where crown fires are frequent.
The ecological significance of canopy seed storage in fire-prone environments: a model for non-sprouting shrubs
This result is interpreted as a bet-hedging strategy whereby spontaneous release of some seeds during the inter-fire period permits recruitment on rare occasions where fire interval approaches or exceeds the species longevity.
Spatial variation of seedling distribution in an east Mediterranean pine woodland at the beginning of post-fire succession
Most of the area in pine woodlands is occupied by perennial seeders that regenerate from seeds in the first winter after the fire and by annuals. Control of the germination in the regenerating
