Fossils cast doubt on climate-change projections on habitats

Mammals didn't play by the rules of modeling on where they migrated to survive last ice age, says UO researcher

Leave it to long-dead short-tailed shrew and flying squirrels to outfox climate-modelers trying to predict future habitats.

Evidence from the fossil record shows that gluttonous insect-eating shrew didn't live where a species distribution technique drawn by biologists put it 20,000 years ago to survive the reach of glaciers, says University of Oregon geologist Edward B. Davis. The shrew is not alone.
