Short summary
Acacia longifolia is an aggressive invader worldwide, which was brought to Portugal by the forestry services and spread throughout the country with very strong ecological and social impacts. We used a molecular approach to understand the genetic variability and genetic differentiation. Our analysis showed that populations at all sampled locations have similar levels of diversity and relatively low differentiation, suggesting a single original introduction and a subsequent acclimation process.
