Biodiversity and late Neanderthal survival

There's an interesting tidbit in today's Science Daily about how a refugium area around Gibraltar may have helped Neanderthal foragers survive there up to ten millennia later than elsewhere in Europe.

"... when a large part of the European continent was covered in ice and snow, Neanderthals in the region of Gibraltar in the south of the Iberian peninsula were able to survive because of the refugium of plant and animal biodiversity. Today, plant fossil remains discovered in Gorham's Cave confirm this unique diversity and wealth of resources available in this area of the planet."
