1. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER
2. Population dynamics of the spruce bark beetle Ips typographus in forest conservation areas and the interaction with biodiversity and natural enemies
Master-uppsats, SLU/Dept. of EcologySammanfattning : Biodiversity is rapidly decreasing and in need of more conservation efforts. However, the tree-killing European spruce bark beetle, Ips typographus (L.), has made forest conservation controversial by affecting conservation areas and possibly adjoining managed forests, yet is still a keystone species leaving decaying wood promoting biodiversity.

3. Granbarkborreangrepp i och kring naturreservat : hur påverkar åtgärder?
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Granbarkborren (Ips typographus) orsakar en stor skada i dom svenska skogarna. Från dom senaste 120 åren finns data som visar många av dom större granbarkborreangreppens påverkan. Inget utbrott finns registrerat som går att jämföra med det utbrott som startade efter den rekordvarma sommaren 2018. LÄS MER
4. Emergence patterns of Ips typographus and Medetera spp. after overwintering in killed spruce trees
Master-uppsats, SLU/Dept. of EcologySammanfattning : Ips typographus (Coleoptera: Curculionidae, Scolytinae) is a pest species that mainly attacks Norway spruce (Picea abies L. Karst.) and can kill large volumes of spruce trees during outbreaks, leading to economic losses of great magnitude. A common practice to manage attacks is to remove recently killed trees and thereby remove the beetles. LÄS MER
5. Multi-scale Bark Beetle Predictions Using Machine Learning
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. LÄS MER
