Red squirrels in Britain
Red squirrels (Sciurus vulgaris) thrive in the north of England and Scotland and occupy a patchwork of highly fragmented woodland habitats. In the September 21 Science, Marie Hale and colleagues from the University of Newcastle, UK, report a genetic investigation of the impact of habitat fragmentation on British red squirrel populations (Science 2001, 293:2246-2248).They assembled over 100 squirrel samples collected between 1918 and 2000 and analysed four polymorphic microsatellite loci for each
