By Sara Vicente, Cristina Máguas and Helena Trindade. Abstract Acacia longifolia is an aggressive invader worldwide. This species was brought to Portugal by the forestry services and is now found throughout the country with very strong ecological and social impacts. Although several ecological and physiological studies have been carried out, molecular studies in this species are…

Human‐mediated introductions of Australian acacias – a global experiment in biogeography
By David M. Richardson, Jane Carruthers, Cang Hui, Fiona A. C. Impson, Joseph T. Miller, Mark P. Robertson, Mathieu Rouget, Johannes J. Le Roux and John R. U. Wilson. Abstract Aim Australian acacias (1012 recognized species native to Australia, which were previously grouped in Acacia subgenus Phyllodineae) have been moved extensively around the world by humans over the past 250 years. This has created the opportunity to…
Do climatic and habitat conditions affect the reproductive success of an invasive tree species? An assessment of the phenology of Acacia longifolia in Portugal
By Patrícia Fernandes, Carla Antunes, Otília Correia and Cristina Máguas. Abstract Plant phenological events are some of the most sensitive indicators of how plant species respond to favourable or stressful conditions. The evaluation of the flowering phenology of invasive plant species is particularly relevant, mainly due to its crucial importance in determining plant reproductive success…
Traits Associated with Invasiveness in Alien Plants: Where Do we Stand?
By Petr Pyšek and David M. Richardson. Abstract Any organism must be equipped for life in a given environment, otherwise it will die. The fundamental question is how well does an organism need to be “equipped”,or what syndrome of traits must it possess to survive and flourish at a given locality. In the current human-mediated biodiversity crisis,…
Assessing the suitability and safety of a well-known bud-galling wasp, Trichilogaster acaciaelongifoliae, for biological control of Acacia longifolia in Portugal
By Hélia Marchante, Helena Freitas and J. H. Hoffmman. Abstract Acacia longifolia is a widespread invasive plant species in Portugal. In South Africa, it is controlled by a bud-galling wasp, Trichilogaster acaciaelongifoliae, which could also be used in Portugal. Biological control of invasive alien plants has received little consideration anywhere in Europe and has never been attempted…
Impacts of invasive Australian acacias: implications for management and restoration
By David C. Le Maitre, Mirijam Gaertner, Elizabete Marchante, Emilie‐Jane Ens, Patricia M. Holmes, Aníbal Pauchard, Patrick J. O’Farrell, Andrew M. Rogers, Ryan Blanchard, James Blignaut, David M. Richardson Abstract Aim The biophysical impacts of invasive Australian acacias and their effects on ecosystem services are explored and used to develop a framework for improved restoration practices. Location South Africa,…
