In the late 1920s, people intentionally introduced birds known as Japanese white-eyes into Hawaiian agricultural lands and gardens for purposes of bug control. Now, that decision has come back to bite us. A recent increase in the numbers of white-eyes that live in old-growth forests is leaving native bird species with too little to eat, according to a report published online on September 17th in Current Biology. The findings show that introduced species can alter whole communities in significant ways and cause visible harm to the birds that manage to survive. http://www.physorg.com/news172409454.html Biology Thu, 17 Sep 2009 12:32:00 EST news172409454 Damming of the Colorado River over the last century, alongside introduction of game fish species, has led to an extensive decline in numbers of native fish whilst introduced species have flourished. Scientists have found that physical changes which occur to a river when it is dammed have had an adverse effect only on native fish, due to differences in their life histories. http://www.physorg.com/news134899161.html Space & Earth Thu, 10 Jul 2008 08:59:21 EST news134899161
