Abstract
Though observations on re-colonisation of post-fire sites in the Mediterranean Basin are plentiful, there still is an ongoing debate on the interrelation of fire regimes and species traitsrelated to fire adaptation. Most of the studies found are restricted to particular species or claim to present community attributes. Therefore they often lack information for the evaluation of evolutionary evidence and historical contingency of the local fire regime and other abiotic conditions, which may act as selective pressure for plant regeneration strategies. Indeed, knowledge about the success of regeneration mechanisms and their interrelation with ecological factors is essential for the interpretation of the high spatio-temporal variability found in post-fire species performance.Such knowledge would be necessary to assess the potential of different regeneration mechanisms to cope with ongoing land-use and climatechange — a crucial scientific challenge. 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. Moreover, the positive or negative impacts of particular parameters of a fire regime on different regeneration strategies (post-fire seeders, resprouters, and facultativeresprouters) are explained and discussedin the light of published literature. To conclude, reference is made to scientific gaps that need to befilled in order to analyse species resistance and community resilience absorbing possible climate or land use changes.
