1. 1. Assessing the Effectiveness of Urban Trees with Skeletal Soils in Flood Risk Mitigation

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Molly Boberg; [2024]
   Nyckelord :Flood Management; Climate Adaptation; Nature-Based Solutions NBS ; Urban Trees; Skeletal Soil; Hydrologic Modelling; MIKE; Översvämningshantering; Klimatanpassning; Naturbaserade lösningar; Stadsträd; Skelettjord; Hydrologisk modellering; MIKE;

   Sammanfattning : With increased urbanization and climate change, heavy rainfall events and urban floods are becoming more frequent. To meet the demands for effective climate adaptation strategies and mitigation measures, Nature-Based Solutions (NBS) have received increased attention. LÄS MER

3. 2. Predicting user churn using temporal information : Early detection of churning users with machine learning using log-level data from a MedTech application

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Love Marcus; [2023]
   Nyckelord :User churn; Customer attrition; Artificial neural networks; Log-level analysis; Random forests; Decision trees; Användarbortfall; Kundbortfall; Artificiella neurala nätverk; logganalys; Slumpskogar; Beslutsträd;

   Sammanfattning : User retention is a critical aspect of any business or service. Churn is the continuous loss of active users. A low churn rate enables companies to focus more resources on providing better services in contrast to recruiting new users. LÄS MER

4. 3. Ectomycorrhizal fungi community shift along gradient from forest to clearcut : two field seasons after harvest of old growth Scots pine forests

   Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

   Författare :Linda Johannesson; [2023]
   Nyckelord :biodiversity; ectomycorrhiza; retention trees; ; fungi; clearcutting;

   Sammanfattning : It is known that the number of ECM decline and the community composition is altered by clearcutting. This study aims to investigate impacts at a more detailed scale. LÄS MER

5. 4. The impact of forest management methods on the ectomycorrhizal community and implications for forest productivity in needleleaf forests

   Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Författare :Oskar Göransson; [2023]
   Nyckelord :Ectomycorrhiza; forestry; clearcutting; continuous cover forestry; biodiversity; forest productivity; Earth and Environmental Sciences;

   Sammanfattning : Ectomycorrhizal fungi (ECM) form symbiotic relationships with trees by connecting to the roots, procuring soil nutrients in exchange for carbohydrates, and are an important contributor to plant growth. The forestry practice of clearcutting can be detrimental to the ECM community by removing its source of energy and creating unfavorable soil conditions, acutely reducing ECM diversity. LÄS MER

7. 5. Effects of management and plant traits on tree-related microhabitats in second-growth stands of the Białowieża Forest

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Weronika Mysiak; [2022]
   Nyckelord :tree-related microhabitats; TreMs; Białowieża Forest; post-Century stands; second-growth forest;

   Sammanfattning : The study presents research conducted on Tree-related Microhabitats (TreM) in managed stands and nearly unmanaged stands in the Białowieża Forest (BF). A TreM is an above-ground structure that creates substrate, site or place for forest-dwelling species, and could be an important tool for assessing the level of biodiversity. LÄS MER
