“…Trade between China and the United States is rising, and the similar climates of the two countries increases the likelihood that accidental introductions will result in unwanted naturalization and/or invasion of new species (Jenkins and Mooney, 2006). Currently, over half of the invasive plant species in China are native to the Americas (Xu et al, 2006;, and they have already generated serious economic impacts. In 2000, invasive species in China were responsible for US $14 billion in economic losses, or 1.3% of China's gross domestic product (Xu et al, 2006).…”

Patterns of genetic diversity reveal multiple introductions and recurrent founder effects during range expansion in invasive populations of Geranium carolinianum (Geraniaceae)

et al. 2013

Genetic diversity, and thus the adaptive potential of invasive populations, is largely based on three factors: patterns of genetic diversity in the species' native range, the number and location of introductions and the number of founding individuals per introduction. Specifically, reductions in genetic diversity ('founder effects') should be stronger for species with low withinpopulation diversity in their native range and few introductions of few individuals to the invasive range. We test these predictions with Geranium carolinianum, a winter annual herb native to North America and invasive in China. We measure the extent of founder effects using allozymes and microsatellites, and ask whether this is consistent with its colonization history and patterns of diversity in the native range. In the native range, genetic diversity is higher and structure is lower than expected based on life history traits. In China, our results provide evidence for multiple introductions near Nanjing, Jiangsu province, with subsequent range expansion to the west and south. Patterns of genetic diversity across China reveal weak founder effects that are driven largely by low-diversity populations at the expansion front, away from the introduction location. This suggests that reduced diversity in China has resulted from successive founder events during range expansion, and that the loss of genetic diversity in the Nanjing area was mitigated by multiple introductions from diverse source populations. This has implications for the future of G. carolinianum in China, as continued gene flow among populations should eventually increase genetic diversity within the more recently founded populations.

“…Data of loss and expenditure were also obtained for New Zealand in 2008 (Giera andBell 2009), for a few species in Germany in approximately 2002 (Reinhardt et al 2003), and for 12 species in Sweden in 2006 (Gren et al 2009). Data of economic loss only were obtained for Great Britain in 2010 (Williams et al 2010), and two estimates were obtained for China in 2000, being of indirect economic loss of forest insects and pathogens (Li and Xu 2005) and total economic loss (Xu et al 2006). It should be noted that although all of these studies had the same broad goal to quantify the financial cost of invasive species, they differ greatly in methods, assumptions, data availability, and effort expended, and therefore comparisons can only be made very broadly.…”

Like most jurisdictions, Australia is managing a broad range of invasive alien species. Here, we provide the first holistic quantification of how much invasive species impact Australia's economy, and how much Australia spends on their management. In the 01-02 financial year (June to July), the combined estimated cost (economic losses and control) of invasive species was $9.8 billion, rising to $13.6 billion in the 11-12 financial year. Approximately $726 million of grants funded through the Commonwealth of Australia (i.e. federal funding) was spent on invasive species management and research between 1996 to 2013. In 01-02, total national expenditure on invasive species was $2.31 billion, rising to $3.77 billion in 11-12. Agriculture accounted for more than 90% of the total cost. For 01-02 and 11-12, these expenditure figures equate to $123 and $197 per person per year respectively, as well as 0.32 and 0.29% of GDP respectively. All values provided here are most likely to be underestimates of the real values due to the significant constraints of the data obtainable. Invasive species are clearly a significant economic burden in Australia. Given the extent of the issue of invasive species globally, there is a clear need for better quantifications of both economic loss and expenditure in more jurisdictions, as well as in Australia.

“…Perhaps less than 1% of all species that arrive at foreign shores become invaders (Williamson and Fitter 1996), but the few that explode in abundance wreak tremendous environmental and economic damage (Mack et al 2000;Pimentel et al 2000;Xu et al 2006). During the last decade research on invasive species has dramatically increased.…”

“…This growing threat of exchanging invaders between eastern Asia and North America was addressed at the 2004 Beijing International Symposium on Biological Invasions titled 'Species Exchanges Between Eastern Asia and North America: Threats to Environment and Economy'. About 100 scientists from academia, governmental agencies, and other organizations from both regions focused on the current status of species exchange of trans-Pacific invasions Xu et al 2006;Kohli et al 2006), predicting and preventing invasions (Erhenfeld 2006;Williamson 2006;Wu et al 2006), eliminating invaders, understanding invasions (Alpert 2006;Guo 2006;Kitijami et al 2006;Liu and Stiling 2006;Wang et al 2006), and developing policy recommendations (Jenkins and Mooney, 2006) and management approaches (Gu 2006). This special feature was motivated, in part, by the outcome of the symposium.…”
