Ecological research and conservation manangement in the Cape Floristic Region between 1945 and 2015: History, current understanding and future challenges
(Taylor & Francis, 2016)In 1945, the Royal Society of South Africa published a wide-ranging report, prepared by a committee led by Dr C.L. Wicht, dealing with the preservation of the globally unique and highly diverse vegetation of the south-western ... -
Effects of habitat fragmentation on bird communities of sand forests in southern Mozambique
(2007)We investigated the influence of forest fragment size and isolation on the bird assemblages in the species- and endemic-rich sand forests of the Maputaland Centre of Endemism, southern Mozambique. Point centre surveys were ... -
Elucidating the native sources of an invasive tree species, Acacia pycnantha, reveals unexpected native range diversity and structure
(Oxford University Press, 2013)† Background and Aims Understanding the introduction history of invasive plant species is important for their management and identifying effective host-specific biological control agents. However, uncertain taxonomy, intra- ... -
Emerging infectious diseases and biological invasions: a call for a One Health collaboration in science and management
(The Royal Society Publishing, 2019)The study and management of emerging infectious diseases (EIDs) and of biological invasions both address the ecology of human-associated biological phenomena in a rapidly changing world. However, the two fields work mostly ... -
Evaluating the invasiveness of Acacia paradoxa in South Africa
(2009-08-13)We present the first detailed survey of a population of Acacia paradoxa DC. (syn. Acacia armata R.Br.), Kangaroo Thorn, in South Africa. The species is listed under the Conservation of Agricultural Resources Act as a ... -
Even well-studied groups of alien species might be poorly inventoried: Australian Acacia species in South Africa as a case study
(Pensoft, 2018)Understanding the status and extent of spread of alien plants is crucial for effective management. We explore this issue using Australian Acacia species (wattles) in South Africa (a global hotspot for wattle introductions ... -
The first management of a marine invader in Africa: the importance of trials prior to setting long-term management goals
(2020)Biological invasions severely impact on marine ecosystems around the world, but to date management is rare and has not previously been attempted in Africa. This study documents a trial management programme aimed at informing ... -

Forestry trial data can be used to evaluate climate-based species distribution models in predicting tree invasions
(Pensoft Publishers, 2014)Climate is frequently used to predict the outcome of species introductions based on the results from species distribution models (SDMs). However, despite the widespread use of SDMs for pre- and post-border risk assessments, ... -
A four-component classification of uncertainties in biological invasions: implications for management
(John Wiley & Sons, Inc, 2019)Although uncertainty is an integral part of any science, it raises doubts in public perception about scientific evidence, is exploited by denialists, and therefore potentially hinders the implementation of management ... -
Framework and guidelines for implementing the proposed IUCN Environmental Impact Classification for Alien Taxa (EICAT)
(John Wiley & Sons Ltd, 2015)Recently, Blackburn et al. (2014) developed a simple, objective and transparent method for classifying alien taxa in terms of the magnitude of their detrimental environmental impacts in recipient areas. Here, we present a ... -
A framework for engaging stakeholders on the management of alien species
(Elsevier Ltd., 2018)Alien species can have major ecological and socioeconomic impacts in their novel ranges and so effective management actions are needed. However, management can be contentious and create conflicts, especially when stakeholders ... -
Genetic diversity and structure of the globally invasive tree, Paraserianthes lophantha subspecies lophantha, suggest an introduction history characterised by varying propagule pressure
(Springer, 2016)An emerging insight in invasion biology is that intra-specific genetic variation, human usage, and introduction histories interact to shape genetic diversity and its distribution in populations of invasive species. We ... -
Global actions for managing cactus invasions
(2019)The family Cactaceae Juss. contains some of the most widespread and damaging invasive alien plant species in the world, with Australia (39 species), South Africa (35) and Spain (24) being the main hotspots of invasion. The ... -
A global assessment of a large monocot family highlights the need for group-specific analyses of invasiveness
(Oxford University Press, 2016)Significant progress has been made in understanding biological invasions recently, and one of the key findings is that the determinants of naturalization and invasion success vary from group to group. Here, we explore this ... -
The global distribution of bamboos: assessing correlates of introduction and invasion
(Oxford University Press, 2017)There is a long history of species being moved around the world by humans. These introduced species can provide substantial benefits, but they can also have undesirable consequences. We explore the importance of human ... -
Global environmental and socio-economic impacts of selected alien grasses as a basis for ranking threats to South Africa
(Creative Commons CC-BY 4.0, 2018)Decisions to allocate management resources should be underpinned by estimates of the impacts of biological invasions that are comparable across species and locations. For the same reason, it is important to assess what ... -
Grasses as invasive plants in South Africa revisited: patterns, pathways and management
(AOSIS, 2017)Background: In many countries around the world, the most damaging invasive plant species are grasses. However, the status of grass invasions in South Africa has not been documented recently. Objectives: To update Sue ... -
Herbivores, but not other insects, are scarce on alien plants
(Ecological Society of Australia, 2008)Understanding how the landscape-scale replacement of indigenous plants with alien plants influences ecosystem structure and functioning is critical in a world characterized by increasing biotic homogenization. An important ... -
Historical legacies accumulate to shape future biodiversity in an era of rapid global change
(John Wiley & Sons Ltd, 2015)Aim Biodiversity responses to changing environmental forcing on species are often characterized by considerable time-lags (= relaxation times). Although changes to the occurrence and abundance of species likely have cascading ...
