Blue rings in trees and shrubs as indicators of early and late summer cooling events at the northern treeline. [PDF]

Front Plant Sci
The high temperature sensitivity of pine trees in northern Fennoscandia has led to some of the most reliable tree-ring climate reconstructions in the world for the past millennia. However, wood anatomical anomalies that likely reflect temperature-induced

Impact of pollution on the temperature sensitivity of multiple Norway spruce tree-ring parameters in Central Europe [PDF]

Central European forests experienced high rates of air pollution in the second half of the 20th century, especially along the borders of Czechia, Germany and Poland. Consequently, tree-growth declines were detected in heavily polluted forests.
