Invasive species lie in wait, strike after decades http://apocadocs.com/s.pl?1293050234
Species that are moved away from their natural predators back home can displace native species in their new habitats, and scientists say the problem already costs Europe 12 billion euros ($16 billion) a year.
The study, which is likely to hold true for other continents too, means that the seeds of future, perhaps bigger, problems have literally already been sown.
The study compared the effects of "alien species" such as American ragweed, Canada geese or Japanese deer in 28 European countries.
The study's findings indicated that it can take decades to figure out which alien species will be disruptive, and looking at those that arrived in 1900 was a better indicator of current problems than looking at those from 2000.
