Some subcortical insects have devastating effects on native tree communities in new ranges, despite benign interactions with their historical hosts. E...

Hosts may evolve defences that make them less susceptible and suitable to herbivores impacting their fitness. Due to climate change-driven range expan...

Trees of two Scots pine phenotypes (poor and fertile soils) and lodgepole pine (intermediate) were exposed side by side in a field study. Biomass cons...

Plant stress from causes such as drought is thought to increase the susceptibility of plants to herbivore attack and damage. Although this forms the b...

During winter 1987-88 and 1988-89 in Quebec, food quality (protein, total non-structural carbohydrates (TNC) and phenolics) was much greater, and vari...

The causes of bark beetle outbreaks - particularly the role of disturbances - are poorly understood. Stand-scale disturbances, like fires, can suddenl...

In a field experiment in central Sweden, shoots of 20-year-old Scots pine (Pinus sylvestris) were hand-pruned in 2 series, 1 with non-fertilized trees...

Herbivores make decisions at different spatial levels in response to food plant quality and quantity. Although experiments have examined the responses...

Large-scale insect outbreaks provide an ideal system to examine the cascade of ecological effects of disturbance regimes across forested landscapes. A...

Historical reference conditions have long been used to guide the restoration of degraded ecosystems. However, a rapidly changing climate and altered d...
