Leif Kullman, Professor of Physical Geography at Umeå University, along with fellow researchers, found the tree growing amid the remains of four generations of spruce dating from 375 to well over 9,000 years old. Researchers are excited about having a long case study of how past climate changes affe...
The same factors that increase the risk of species extinctions also reduce the chance that new species are formed. This is concluded by two biologists at Umeå University. Their findings are published in the April issue of the scientific journal Evolution.
With people travelling all over the place, plants are spread to environments where they would not normally grow.
