Two studies in the Feb. 6 <em>Nature<\/em> report that one reason invasive  species are so successful is because  the enemies that kept them in  check at home are usually left behind. Ecologists from Cornell  University examined invasive plants, and researchers from the University  of California at Santa Barbara studied invasive animals. It was found  that, in general, invasive species had only half as many parasites and  pathogens as native species. How do they manage to ditch their enemies?  One hypothesis is that for parasites that live on more than one host  species, a migration of two or more species might be required for them  to survive. According to both studies, one way to control invaders would  be to import their original enemies, but if the introduced pest turns  out to like native species, too, that opens a whole new can of  parasites. <\/span><\/p>\n<h6><em>This news brief appeared in the Random Data column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 2\/18\/2003.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Plants such as kudzu and animals such as zebra mussels, which can be harmless in their country of origin, can be a pest elsewhere, playing havoc with local wildlife and having huge economic costs.
