Radio-tracking associated with 'dramatic shift' in water vole sex ratio

... sites vole numbers had been monitored using small traps baited with apple and carrot during 2002 and 2003, voles being released after counting. However, Moorhouse and Macdonald had also fitted radio-collars to 38 of the voles caught at the Norfolk site for in-depth study of the voles' movements. Accordin...
