1. Och då du länge blickar in i en avgrund, blickar avgrunden också in i dig. : Ekofobi och kolonial ångest i Joseph Conrads Heart of Darkness och Algernon Blackwoods The Man Whom the Trees Loved
Kandidat-uppsats, Södertörns högskola/Institutionen för kultur och lärandeSammanfattning : This thesis aims to examine the manifestation of ecophobia in negative emotional expressions in Heart of Darkness by Joseph Conrad and “The Man Whom the Trees Loved” by Algernon Blackwood and how this relates to colonialism and colonial anxiety. The term ecophobia, popularized by Simon C. LÄS MER
2. 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
3. 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.

4. Granbarkborren i svenska produktionsskogar : vilka faktorer påverkar massutbrott och vilka åtgärder kan vidtas för att minska dem?
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Granbarkborren, Ips typographus, är en av få arter som kan öka drastiskt i populationsdensitet och leda till en omfattande dödlighet av träd i skogen. Skadorna år 2020 uppgick till ett värde på 3,5 miljarder kronor, vilket gör det värdefullt att försöka förstå varför dessa utbrott sker och vad för åtgärder som kan vidtas för att undvika dem.

5. Influence of forest mires on wildfire : a landscape analysis of the 2014 Västmanland forest fire
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Forest fire is a major natural disturbance that influence forest ecosystem structure and composition at both the stand and landscape level. In boreal Fennoscandia fire frequency has been very low over the last c.150 years due to effective fire suppression, although occasionally high-intensity fires escape initial attack and grow big.
