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

...hey noticed a 48% decline in the number of females born at the Norfolk site. At both 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 v...

In rats, Day 4 is like the third trimester in human pre...
