As climate changes, the effects of forest diseases on forest ecosystems will change. We
review knowledge of relationships between climate variables and several forest diseases …

The extreme drought event that occurred in Western Europe during 2003 highlighted the
need to understand the key processes that may allow trees and stands to overcome such …

Most members of the oomycete genus Phytophthora are primary plant pathogens. Both soil-
and airborne Phytophthora species are able to survive adverse environmental conditions …

Tree decline is a global concern and the primary cause is often unknown. Complex
interactions between fluctuations in nitrogen (N) and acidifying compounds have been …

Common ash (Fraxinus excelsior) is a keystone tree species throughout temperate Europe
whose future existence is threatened by an emerging invasive fungal disease. Ash dieback …

An increasing number of studies have reported on forest declines and vegetation shifts
triggered by drought. In the Swiss Rhone valley (Valais), one of the driest inner‐Alpine …

Increasing temperatures are driving rapid upward range shifts of species in mountains. An
altitudinal range retreat of 10 m is predicted to translate into a∼ 10-km latitudinal retreat …

For north-eastern Germany regional climate models project rising temperatures in
combination with decreasing summer and increasing winter precipitation. The resulting …

Like all other plants, trees are vulnerable to attack by a multitude of pests and pathogens.
Current control measures for many of these diseases are limited and relatively ineffective …

We review here our own research and related work on hybridization between two
widespread and largely sympatric European oak species (Quercus petraea and Q. robur) …
