Lack of human-assisted dispersal means Pueraria montana var. lobata (kudzu vine) could still be eradicated from South Africa
(Springer, 2016)The legume, Pueraria montana var. lobata (kudzu vine) is one of the worst plant invaders globally. Here we present the first study of P. montana in South Africa. We found only seven P. montana populations covering an ... -
Landscape corridors: Possible dangers?

Level of environmental threat posed by horticultural trade in Cactaceae
(Society of Conservation Biology, 2017)Ornamental horticulture has been identified as an important threat to plant biodiversity and is a major pathway for plant invasions worldwide. In this context, the family Cactaceae is particularly challenging because it ... -
MAcroecological Framework for Invasive Aliens (MAFIA): disentangling large-scale context dependence in biological invasions
(2020)Macroecology is the study of patterns, and the processes that determine those patterns, in the distribution and abundance of organisms at large scales, whether they be spatial (from hundreds of kilometres to global), ... -
Macroecology meets invasion ecology: linking the native distributions of Australian acacias to invasiveness
(2011)Aim Species’ native ranges reflect the net outcome of interactions between lifehistory strategies and biotic and abiotic influences over evolutionary time-scales. Differences in native ranges might be indicative both of ... -
Macroecology meets invasion ecology: performance of Australian acacias and eucalypts around the world revealed by features of their native ranges
(Springer, 2014)Native geographical range extent has frequently emerged as a correlate of invasiveness, especially for plant species. We tested whether dimensions of the native range (measured by the area-of-occupancy and its scaling ... -
Management history determines gene flow in a prominent invader
(Nordic Society Oikos, 2013)Invasive plants pose substantial threats to protected areas globally. Although management can limit impacts, spread and reinvasion from neighbouring areas into protected areas are a major and an ongoing problem for land ... -
Melaleuca parvistaminea Byrnes (Myrtaceae) in South Africa: Invasion risk and feasibility of eradication
(Elsevier, 2014)We document and assess management options for the first reported invasion of Melaleuca parvistaminea Byrnes (initially identified asM. ericifolia) in the world, in the context of a South African wetland ecosystem. Delimitation ... -
Methods and approaches for the management of arthropod border incursions
(Springer, 2016)Biological invasions are increasing and are strongly associated with negative agricultural, economic and ecological impacts. It is increasingly recognized that the primary focus in minimizing biological invasions should ... -
Molecular systematics and ecology of invasive kangaroo paws in South Africa: management impications for a horticulturally important genus
(SpringerLink, 2010)Most legislation pertaining to non-native organisms is implicitly focussed at the individual species level. However, in some cases interspecific hybrids can be more invasive than any of the parent species. This is problematic ... -
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 ... -
Much more give than take: South Africa as a major donor but infrequent recipient of invasive non-native grasses
(John Wiley & Sons Ltd, 2016)Aim Some regions donate more invaders from particular taxonomic and functional groups than they receive. We demonstrate a particularly striking donor–recipient asymmetry in invasion ecology in grasses. Specifically, we ... -
National-scale strategic approaches for managing introduced plants: insights from Australian acacias in South Africa
(Blackwell Publishing Ltd, 2011)Aim A range of approaches and philosophies underpin national-level strategies for managing invasive alien plants. This study presents a strategy for the management of taxa that both have value and do harm. Location South ... -
Native and naturalized range size in Pinus: Relative importance of biogeography, introduction effort and species traits
(Blackwell Publishing, 2012)Aim Pine trees (genus Pinus) represent an ancient lineage, naturally occurring almost exclusively in the Northern Hemisphere, but introduced and widely naturalized in both hemispheres. As large trees of interest to ... -
Native range size and growth form in Cactaceae predict invasiveness and impact
(Pensoft, 2016)Many recent studies in invasion science have identified species traits that determine either invasiveness or impact. Such analyses underpin risk assessments and attempts to prioritise management actions. However, the ... -
A new national unit for invasive species detection, assessment and eradication planning
(Academy of Science of South Africa, 2013)Even with no new introductions, the number of biological invasions in South Africa will increase as introduced species naturalise and become invasive. As of 2010 South Africa had ~8750 introduced plant taxa, 660 recorded ... -
Non-native species in urban environments: patterns, processes, impacts and challenges
(Springer, 2017)Although urban ecosystems are hotspots for biological invasions, the field of invasion science has given scant attention to invasion dynamics and the challenges facing managers in towns and cities. This paper provides ... -
Nonrandom extinction leads to elevated loss of angiosperm evolutionary history
(Blackwell Publishing Ltd/CNRS, 2008)The phylogenetic clustering of extinction may jeopardize the existence of entire families and genera, which can result in elevated reductions of evolutionary history (EH), trait diversity, and ecosystem functioning. Analyses ... -
Organismal complexity is an indicator of species existence value

Ornamental plants as invasive aliens: problems and solutions in Kruger National Park, South Africa
(Springer Science+Business Media, LLC, 2008)The most widespread invasive alien plant species in South Africa’s Kruger National Park (KNP) were either introduced unintentionally along rivers and roads, or intentionally for use as ornamentals. We examine the spatial ...
