The balance of trade in alien species between South Africa and the rest of Africa

Faulkner, K.T.; Hurley, B.P.; Robertson, M.P.; Rouget, M.; Wilson, J.R.U. (AOSIS, 2017)

Background: Alien organisms are not only introduced from one biogeographical region to another but also spread within regions. As South Africa shares land borders with six countries, multiple opportunities exist for the ...

The (bio)diversity of science reflects the interests of society

Wilson, J.R.U.; Procheş, Ş.; Braschler, B.; Dixon, E.S.; Richardson, D.M. (2007)

For ecologists to develop robust generalizations and principles, a broad taxonomic and geographic spread of research is required, but, in practice, most generalizations are based on the research of individual scientists ...

Biogeographic concepts define invasion biology

Wilson, J.R.U.; Dormontt, E.E.; Prentis, P.J.; Lowe, A.J.; Richardson, D.M. (Elsevier, 2009-11)

Biological invasions and natural colonisations are different – the need for invasion science.

Wilson, J.R.U.; Garcia-Diaz, P.; Cassey, P.; Richardson, D.M.; Pysek, P.; Blackburn, T.M. (Pensoft, 2016)

In a recent Discussion Paper, Hoffmann and Courchamp (2016) posed the question: are biological invasions and natural colonisations that different? This apparently simple question resonates at the core of the biological ...

Biological invasions in the Cape Floristic Region: history, current patterns, impacts, and management challenges

Wilson, J.R.; Gaertner, M.; Griffiths, C.L.; Kotze, I.; Le Maitre, D.C.; Marr, S.M.; Picker, M.D.; Spear, D.; Stafford, L.; Richardson, D.M.; van Wilgen, B.W.; Wannenburg, A. (Oxford University Press, 2015)

The Cape Floristic Region (CFR) is the most invaded terrestrial area in South Africa in terms of: the conspicuous prominence of (mainly woody) invasive plants (Fig 12.1, Plate 12) (Henderson 2007); the area invaded as ...

Border control for stowaway alien species should be prioritised based on variations in establishment debt

Faulkner, K.T.; Robertson, M.P.; Rouget, M.; Wilson, J.R.U. (Elsevier Ltd, 2016)

Border control is one of the major approaches used by countries to limit the number of organisms introduced as stowaways. However, it is not feasible to inspect all passengers, cargo and vehicles entering a country, and ...

Casuarina cunninghamiana in the Western Cape, South Africa: Determinants of naturalisation and invasion, and options from management

Potgieter, L.J.; Richardson, D.M.; Wilson, J.R.U. (Elsevier, 2014-05)

Alien species that are desirable and commercially important in some parts of the landscape but damaging invaders in other parts present a special challenge for managers, planners, and policy-makers. Casuarina cunninghamiana ...

Casuarina: biogeography and ecology of an important tree genus in a changing world

Potgieter, L.J.; Richardson, D.M.; Wilson, J.R.U. (Springer, 2014)

Important insights on the invasion ecology of woody plants are emerging from the study of model groups, but it is important to test how widely such results can be generalised. We examined whether drivers of introduction ...

Changes in the composition and distribution of alien plants in South Africa: An update from the Southern African Plant Invaders Atlas

Henderson, L.; Wilson, J.R.U. (AOSIS, 2017)

Background: Data on alien species status and occurrence are essential variables for the monitoring and reporting of biological invasions. The Southern African Plant Invaders Atlas (SAPIA) Project has, over the past 23 ...

The Chilean black urchin, Tetrapygus niger (Molina, 1782) in South Africa: gone but not forgotten

Mabin, C.A.; Wilson, J.R.U.; Robinson, T.B. (REABIC, 2015)

It is important to keep lists of invasive and alien species up to date, but it can be difficult to determine when species should be removed from such lists. One such example is the urchin, Tetrapygus niger (Molina, 1782), ...

Co-invasion of South African ecosystems by an Australian legume and its rhizobial symbionts

Ndlovu, J.; Richardson, D.M.; Wilson, J.R.U.; Le Roux, J.J. (Blackwell Publishing Ltd., 2013)

Woodford, D.J.; Richardson, D.M.; MacIsaac, H.J.; Mandrak, N.E.; van Wilgen, B.W.; Wilson, J.R.U.; Weyl, O.L.F. (Pensoft, 2016)

The Anthropocene Epoch is characterized by novel and increasingly complex dependencies between the environment and human civilization, with many challenges of biodiversity management emerging as wicked problems. Problems ...

Contain or eradicate? Optimizing the management goal for Australian acacia invasions in the face of uncertainty

Moore, J.L.; Runge, M.C.; Webber, B.L.; Wilson, J.R.U. (Blackwell Publishing Ltd, 2011)
