Berkeley, California - Two thousand California honey bees may have a story to tell. So too, more than 10,000 deer mice, and 3,000 oaks. Specimens of these plants and animals populate massive collections in Berkeley’s renowned research museums, and are now being enlisted as guides to past episodes of habitat and climate change.
Plant ecologist David Ackerly has calculated that some animals and plants would need to migrate as much as four miles a year to track their preferred temperature in a rapidly warming climate.
