Abstract. 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 activities on the processes of species dissemination and potential invasions using the Poaceae subfamily Bambusoideae (‘bamboos’), a group that contains taxa that are widely utilised and that are often perceived as weedy. We (1) compiled an inventory of bamboo species and their current distributions; (2) determined which spe- cies have been introduced and become invasive outside their native ranges; and (3) explored correlates of introduc- tion and invasion. Distribution data were collated from Kew’s GrassBase, the Global Biodiversity Information Facility and other online herbarium information sources. Our list comprised 1662 species in 121 genera, of which 232 (14 %) have been introduced beyond their native ranges. Twelve (0.7 % of species) were found to be invasive. A non- random selection of bamboos have been introduced and become invasive. Asiatic species in particular have been widely introduced. There was a clear over-representation of introduced species in the genera Bambusa and Phyllostachys which also contain most of the listed invasive species. The introduction of species also correlated with certain traits: taxa with larger culm dimensions were significantly more likely to have been moved to new areas; and those with many cultivars had a higher rate of dissemination and invasion. It is difficult to determine whether the patterns of introduction and invasion are due simply to differences in propagule pressure, or whether humans have deliberately selected inherently invasive taxa. In general, we suggest that human usage is a stronger driver of intro- ductions and invasions in bamboos than in other taxa that have been well studied. It is likely that as bamboos are used more widely, the number and impact of invasions will increase unless environmental risks are carefully managed.

Table 2 The effect of biogeographic lineage, culm form and underground rhizome form on whether taxa tended to be introduced or become invasive. Each group was tested independently to determine whether species in a particular group or with particular features have been intro- duced and become invasive significantly more often than other bamboo species. This was done using a Fisher’s exact test comparing the num- ber of introduced versus non-introduced species, and invasive versus non-invasive.

Introduction effort Introduction effort, or propagule pressure, has consis- tently been linked with successful invasions as greater numbers of propagules and more frequent introductions mean higher probabilities of invasion (Colautti et al. 2006; Lockwood et al. 2005; Von Holle and Simberloff 2005). The positive correlation of propagule pressure and invasion success has been observed in many taxa includ- ing birds (Duncan 1997; Veltman et al. 1996), mammals (Crowell 1973; Forsyth et al. 2004) and aquatic species (Colautti 2005; Duggan et al. 2006). This is notable with intentional introductions, such as the case with many or- namental (Dehnen-Schmutz and Touza 2008) and culti- vated agricultural (Pysek et al. 2006) plants. We found a clear link between introduction effort and invasiveness in bamboos. Although it was not possible to measure prop- agule pressure directly, species that had been more widely disseminated were much more likely to have be- Figure 3.

Historical activities in the native range have also played an important role in influencing introduction ef- fort. For example, the local propagation and use of native from Asia have been introduced much more often than species may increase the chance of a species becoming species from other regions, and all invasive bamboos are established after introductions (Forcella and Wood 1984, native to Asia.

Figure S2. Phylogenetic tree of 122 bamboo taxa built using collated genetic data for one chloroplast gene region, maturase K (matK). All sequences were retrieved from the online GenBank repository (ncbi.nlm.nih.gov). Six variables are shown in columns alongside tree branches showing cultivars no. (number of cultivars), subspecies no. (number of subspecies), forms no. (number of forms), varieties no. (number of genetic varieties), culm diameter (max culm diameter) and culm height (max culm height) of corresponding species. Data in each column is scaled, where large black-filled circles indicate a higher quantity and white-filled circle indicate a smaller quantity of the particular variable associated with the given species relative to other taxa. Numbers after species names indicate the number of regions of introduction and red circles indicate invasive species.
