“…Invasive Cardiospermum species are considered "transformer weeds" (Mc Kay et al 2010), as they often extensively cover native vegetation, depriving it of sunlight and thus photosynthesis (Mc Kay et al 2010, Simelane et al 2011. Cardiospermum invasions also have substantial economic impacts on sugarcane and soybean production (Johnston et al 1979, Jolley et al 1983, Voll et al 2004, Subramanyam et al 2007, Murty and Venkaiah 2011. For example, in Brazil C. halicacabum reduces soybean crop yields by up to 26% (Dempsey et al 2011, Brighenti et al 2003.…”

Members of the balloon vine genus, Cardiospermum, have been extensively moved around the globe as medicinal and horticultural species, two of which are now widespread invasive species; C. grandiflorum and C. halicacabum. A third species, C. corindum, may also have significant invasion potential. However, in some regions the native status of these species is not clear, hampering management. For example, in South Africa it is unknown whether C. halicacabum and C. corindum are native, and this is a major constraint to ongoing biological control programmes against invasive C. grandiflorum. We review the geography, biology and ecology of selected members of the genus with an emphasis on the two most widespread invaders, C. halicacabum and C. grandiflorum. Specifically, we use molecular data to reconstruct a phylogeny of the group in order to shed light on the native ranges of C. halicacabum and C. corindum in southern Africa. Phylogenetic analyses indicate that southern African accessions of these species are closely related to South American taxa indicating human-mediated introduction and/or natural long distance dispersal. Then, on a global scale we use species distribution modelling to predict potential suitable climate regions where these species are currently absent. Native range data were used to test the accuracy with which bioclimatic modelling can identify the known invasive ranges of these species. Results show that Cardiospermum species have potential to spread further in already invaded or introduced regions in Australia, Africa and Asia, underlining the importance of resolving taxonomic uncertainties for future management efforts. Bioclimatic modelling predicts Australia to have highly favourable environmental conditions for C. corindum and therefore vigilance against this species should be high. Species distribution

“…Entretanto, as plantas daninhas interferem indiretamente no desenvolvimento da cultura, sendo usualmente controladas com aplicações de herbicidas. O controle químico ainda é o preferido entre os agricultores da cultura, representando um dos maiores segmentos da indústria de herbicidas (Correia e Rezende, 2002;Voll et al, 2004). Contudo, a aplicação intensiva de insumos químicos tem gerado discussão pública sobre seus efeitos danosos ao meio ambiente e à saúde (Wu, 2001;Kim et al, 2002;Park et al, 2003).…”

Aim A key aspect of effective invasive plant management is a clear understanding of natal ranges. In the balloon vine genus, Cardiospermum, uncertain native biogeographic ranges are hampering ongoing biological control efforts against invasive taxa in southern Africa. With the objective of minimizing non-target impacts, which are a major concern for conservation, we combine phylogenetic analyses with known native range distributions of selected Cardiospermum species to resolve unknown natal ranges for globally widespread balloon vines which occur in southern Africa.
