Genetic analyses reveal complex introduction histories for the invasive tree Acacia dealbata Link around the world
(2021)Aim To compare genetic diversity and structure between Acacia dealbata populations sampled across the species' native range in Australia and from its non-native ranges in Chile, Madagascar, New Zealand, Portugal, La Reunion ... -
Ghosts from the past: even comprehensive sampling of the native range may not be enough to unravel the introduction history of invasive species – the case of Acacia dealbata invasions in South Africa
(Botanical Society of America, 2019)PREMISE OF THE STUDY: Knowledge about the introduction history (source(s), number and size of introduction events) of an invasive species is a crucial prerequisite to understand invasion success and to facilitate effective ... -
Historical range contraction, and not taxonomy, explains the contemporary genetic structure of the Australian tree, Acacia dealbata Link
(Springer, 2018)Irrespective of its causes, strong population genetic structure indicates a lack of gene flow. Understanding the processes that underlie such structure, and the spatial patterns it causes, is valuable for conservation ... -
Human-mediated introductions of Australian acacias – a global experiment in biogeography
(Blackwell Publishing Ltd, 2011)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 ... -
Montpellier broom (Genista monspessulana) and Spanish broom (Spartium junceum) in South Africa: an assessment of invasiveness and options for management
(2013)The legumes (Fabaceae) Genista monspessulana and Spartium junceum are major invaders in several other parts of the world, but not yet so in South Africa. We determine their current distributions in South Africa at ... -
Seed banks of invasive Australian Acacia species in South Africa: Role in invasiveness and options for management
(Elsevier GmbH., 2008)Despite impressive efforts at clearing stands of invasive Australian Acacia species in South Africa, insufficient attention has been given to understanding the role of seed banks in the invasiveness and long-term persistence ... -
The seed ecology of an ornamental wattle in South Africa - Why has Acacia elata not invaded a greater area?
(Elsevier, 2014)Australian Acacia species introduced to South Africa as ornamentals have notably smaller invasive ranges than those introduced for forestry or dune stabilization.We asked whether the relatively small invasive extent of ... -
Unresolved native range taxonomy complicates inferences in invasion ecology: Acacia dealbata Link as an example
(Springer, 2017)Elaborate and expensive endeavours are underway worldwide to understand and manage biological invasions. However, the success of such efforts can be jeopardised due to taxonomic uncertainty. We highlight how unresolved ...
