Divergent Trends in Insect Disturbance Across Europe's Temperate and Boreal Forests. [PDF]

Glob Chang Biol
Across temperate and boreal Europe, tree mortality caused by insects has risen during the 21st century, yet interactions among insect species and their host trees are complex. While mortality from wood‐boring insects in conifers has increased, defoliation caused by multiple moth species has declined.
