European mad cow outbreak fuelled surge in Canadian birds through 'butterfly effect'
By Randy Boswell, Postmedia News March 8, 2011 7:02 PM
In a study described as a "striking illustration" of the long-distance links between a global trade disruption and impacts in the natural world, two Canadian scientists have connected the dots between the emergence of mad cow disease in Europe in the mid-1980s and a subsequent series of population spikes among grassland birds in southern Saskatchewan, Alberta and Ontario.
The rare example of successfully tracking a "butterfly-effect" linkage between seemingly disparate phenomena, carried out by researchers from Trent University in Peterborough, Ont., showed how 18 of 20 bird species in North America appeared to benefit from the 1985 outbreak of BSE ? bovine spongiform encephalopathy ? after it destroyed cattle herds in Britain and had major impacts elsewhere in Europe...
