Climate drivers of bark beetle outbreak dynamics in Norway spruce forests
2015, Raff a et al. 2015). Given the potential interactions of insect outbreaks with other biotic and abiotic disturbances and the potentially strong impact of changing disturbance regimes on forest resources (Buma 2015), investigating the climate drivers of bark beetle outbreaks is of paramount importance. In Europe, Ips typographus is considered one of the most destructive pests of conifer fo...
متن کاملWestern Spruce Budworm Outbreak History
Western spruce budworm (Choristoneura occidentalis Freeman) outbreak history was reconstructed for the Sacramento Mountains of south -central New Mexico, at the southern limit of the species distribution range. Six host tree -ring width chronologies (Douglas -fir and white fir) and three non -host control chronologies (ponderosa pine) were used for this reconstruction spanning from 1800 to 1990...
متن کاملA common fungal associate of the spruce bark beetle metabolizes the stilbene defenses of Norway spruce.
Norway spruce (Picea abies) forests suffer periodic fatal attacks by the bark beetle Ips typographus and its fungal associate, Ceratocystis polonica. Norway spruce protects itself against fungal and bark beetle invasion by the production of terpenoid resins, but it is unclear whether resins or other defenses are effective against the fungus. We investigated stilbenes, a group of phenolic compou...
متن کاملEvidence of compounded disturbance effects on vegetation recovery following high-severity wildfire and spruce beetle outbreak
Spruce beetle (Dendroctonus rufipennis) outbreaks are rapidly spreading throughout subalpine forests of the Rocky Mountains, raising concerns that altered fuel structures may increase the ecological severity of wildfires. Although many recent studies have found no conclusive link between beetle outbreaks and increased fire size or canopy mortality, few studies have addressed whether these combi...
متن کاملRestoration of a Rocky Mountain Spruce-Fir Forest: Sixth-Year Engelmann Spruce Seedling Response With or Without Tree Shelter Removal
This paper presents results following 6 growing seasons of a project designed to examine the use of tree shelters as a means to provide initial shade for planted Engelmann spruce seedlings. Seedlings were planted in 1996 on a 48-ha (119-ac) high-elevation site with different colors of tree shelters providing various degrees of shading. A control treatment, consisting of shading using debris wit...
