Risk of bark beetle (Coleoptera, Scolytidae) damage in a spruce forest restoration area in central Finland

Silva Fennica, 2008
A beetle inventory using window traps was performed to examine the effect of forest restoration by artificial addition of dead wood on the abundance of beetles and to evaluate the risk of bark beetle damage in a forest restoration area.

A dynamical model for bark beetle outbreaks [PDF]

Journal of Theoretical Biology, 2016
Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern tree resistance.

Spatio-temporal patterns of the Norway spruce decline in the Beskid Śląski and Żywiecki (Western Carpathians) in southern Poland

Journal of Forest Science, 2007
A dramatic forest decline due to the bark beetle outbreak, which occurs in the Norway spruce stands in the Western Beskidy (southern Poland) since 2003, was started after severe physiological drought during winter time. An analysis describing some spatio-

Development and implementation of a spruce bark beetle susceptibility index: A framework to compare bark beetle susceptibility on stand level

Trees, Forests and People, 2023
The spruce bark beetle (spruce bark beetle) (Ips typographus) is one of the major disturbance agents in European forests. Damage by spruce bark beetle is expected to increase in the future, as a result of e.g. increased temperatures.

Small spruce bark beetle as a new challenge for forest protection in Siberia [PDF]

Сибирский лесной журнал, 2023
The problems of protection of Siberian pine forests, that have arisen in connection with the recent invasion of the European pest - the small spruce bark beetle Ips amitinus (Eichh.), which formed the outbreak foci on the territory of the Tomsk and ...

Influence of southern pine beetle on fungal communities of wood and bark decomposition of coarse woody debris in the New Jersey pine barrens

Forestry Research, 2021
Dead coarse woody debris (fungal food resources) on the forest floor is an ignition source for forest fires. The rate of decomposition of the debris is largely influenced by fungi, determining its residence time on the forest floor.

Influence of bark beetle infestation on stem diameter dynamics

Trees, Forests and People
Bark beetle epidemics have increased globally due to drought and a warming climate, impairing forest ecosystem services by inducing severe forest disturbances.

Overlapping outbreaks of multiple bark beetle species are rarely more severe than single‐species outbreaks

Ecosphere, 2023
Biotic disturbances that overlap in space and time may result in important shifts in forest structure and composition, with potential effects on many ecosystem services.

Comparative Analysis of Eight Mitogenomes of Bark Beetles and Their Phylogenetic Implications

Insects, 2021
Many bark beetles of the subfamily Scolytinae are the most economically important insect pests of coniferous forests worldwide. In this study, we sequenced the mitochondrial genomes of eight bark beetle species, including Dendroctonus micans ...
