Forest migration northward. Though "Fagus" and "Picea" populations did not expand directionally, they have grown in the Scandinavian range. The movement of "Picea" species in the past 1000 years has shown a strong connection to climate change through a model comparison. In the more recent past, there has been documentation of elevation shifts in distribution of many core forest tree species of Catalonia. The populations of two tree species (European Beech, "Fagus sylvatica"; and Holm Oak, "Quercus ilex") were evaluated in their dynamics over elevations through time. Generally, Holm Oak reside lower on mountain slopes than does European Beech. In the past
Microseris sylvatica containing up to 70 yellow ray florets. The fruit is an achene with a pale body up to a centimeter long. At the tip of the body is a large pappus made up of several long, barbed, bristly scales each up to a centimeter in length themselves. Microseris sylvatica Microseris sylvatica is a species of flowering plant in the aster family known by the common names sylvan scorzonella and woodland silverpuffs. It is endemic to California, where it has a scattered distribution throughout the central California Coast Ranges and inland mountain ranges, including the Sierra Nevada of the state. Its
