Composition and Elevation of Spruce Forests Affect Susceptibility to Bark Beetle Attacks: Implications for Forest Management
The spruce bark beetle, Ips typographus (L.) (Coleoptera: Curculionidae, Scolytinae), is one of the most destructive insects infesting spruce forests in Europe. Data concerning infestations of I. typographus occurring over the last 19 years (1994–2012) on the Southern Alps were analyzed in seven spruce forest types: (1) pure spruce plantations; (2) pure spruce reforestations; (3) pure spruce mo...
متن کاملIce-age endurance: DNA evidence of a white spruce refugium in Alaska.
Paleorecords offer key information for evaluating model simulations of species migration in response to forecast climatic change. However, their utility can be greatly compromised by the existence of glacial refugia that are undetectable in fossil records (cryptic refugia). Despite several decades of investigation, it remains controversial whether Beringia, the largely unglaciated area extendin...
متن کاملClimate 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 کاملImpacts of fire on non-native plant recruitment in black spruce forests of interior Alaska
Climate change is expected to increase the extent and severity of wildfires throughout the boreal forest. Historically, black spruce (Picea mariana (Mill.) B.S.P.) forests in interior Alaska have been relatively free of non-native species, but the compounding effects of climate change and an altered fire regime could facilitate the expansion of non-native plants. We tested the effects of wildfi...
متن کاملEnvironmental controls on soil CO2 flux following fire in black spruce, white spruce, and aspen stands of interior Alaska
Boreal forests contain large amounts of stored soil carbon and are susceptible to periodic disturbance by wildfire. This study evaluates the relationship between post-fire changes in soil temperature, moisture, and CO2 exchange in paired burned and control stands of three Alaskan forest systems: Picea mariana (Mill.) BSP, Picea glauca (Moench) Voss, and Populus tremuloides Michx. In these syste...
