1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus
Master-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : Rising instances of drought are causing more tree seedling fatalities post-nursery outplanting. In the face of climate change, fostering resilient forestry practices is imperative for preserving the health and functionality of our forests. LÄS MER
2. Systematics and the evolution of flower symmetry of Posoqueria (Rubiaceae)
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : The genus Posoqueria is a Neotropical group of shrubs and trees in the coffee family Rubiaceae. Posoqueria is phylogenetically poorly understood and presents several internal taxonomical difficulties. LÄS MER
3. Branching Out with Mixtures: Phylogenetic Inference That’s Not Afraid of a Little Uncertainty
Master-uppsats, KTH/Matematisk statistikSammanfattning : Phylogeny, the study of evolutionary relationships among species and other taxa, plays a crucial role in understanding the history of life. Bayesian analysis using Markov chain Monte Carlo (MCMC) is a widely used approach for inferring phylogenetic trees, but it suffers from slow convergence in higher dimensions and is slow to converge.

4. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species
Kandidat-uppsats, KTH/Matematisk statistikSammanfattning : The alarming rate at which we see the decline in biodiversity due to human activity has raised concerns about the well-being of our planet. Butterflies which serve as pollinators are an essential part of many ecosystems and sensitive indicators of environmental changes and can provide valuable insight into how ecosystems function and evolve.

5. Phoma i skogsplantskolor : Fylogenetisk karakterisering av Phoma herbarum från svenska skogsplantor
Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : Svenska forskare har märkt av en ökning bland Phoma infekterade skogsplantor från plantskolor runt om i landet. Både skott och rötter från tidigare undersökning har detekterats infekterade med svampar från släktet Phoma. Denna studie undersöker isolat av svamp tagna från rötter och skott på gran och tall från 9 olika plantskolor. LÄS MER
