The article looks at evidence that suggests that boreal conifer tree species persisted in ice-free refugia on the Scandinavian Peninsula during the last ice age. Holocene lake sediment and fossil pollen samples from Trøndelag, Norway, yielded mitochondrial DNA of a rare spruce haplotype native to Scandinavia, suggesting that tree populations survived the glaciation. These findings call into question many scientific assumptions about the geographical distribution and dispersal of tree species in response to climatic changes.
