INTRODUCTION
The effects of disturbance regimes on population
persistence may be particularly important in marginal
populations, i.e. those occurring at geographical and
ecological limits. When populations are already at the
edge of the suitable range of favourable conditions for
their persistence, their resistance and resilience to dis-
turbances may be compromised by the already highly
stressful local conditions and small population sizes
(Guo et al. 2005). Yet, edge populations may develop
unique adaptive traits for the species that confer them
high conservation value and differential persistence
capability when facing future environmental changes
(Vucetich & Waite 2003, Hampe & Petit 2005, Johan-
nesson & André 2006).
