  1. 1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus

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

    Författare :Patricia Salén; [2024]
    Nyckelord :Ectomycorrhiza; drought; Suillus;

    Sammanfattning : 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

  3. 2. Analysis of winter wheat and leafhoppers for wheat dwarf virus : factors causing outbreaks of wheat dwarf disease

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Plant Biology (from 140101)

    Författare :Lina Karm Togo; [2024]
    Nyckelord :Sweden; Psammotettix alienus; DAS-ELISA; cloning; sequencing; BLASTn; BLASTx; MEGA; SDT;

    Sammanfattning : Wheat dwarf disease is caused by wheat dwarf virus (WDV) and is transmitted by the leafhopper Psammotettix alienus. The disease has been reported in many European countries, as well as in West Asia, China, and one country in North Africa. LÄS MER

  4. 3. Systematics and the evolution of flower symmetry of Posoqueria (Rubiaceae)

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Sebastián Giraldo Gómez; [2023-06-14]
    Nyckelord :Posoquerieae; Cinchonoideae; Ixoroideae; Dialypetalanthoideae; Angiosperms 353; target capture; Hybpiper; Pollen Catapult Mechanism.;

    Sammanfattning : 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

  5. 4. Branching Out with Mixtures: Phylogenetic Inference That’s Not Afraid of a Little Uncertainty

    Master-uppsats, KTH/Matematisk statistik

    Författare :Ricky Molén; [2023]
    Nyckelord :Phylogeny; Bayesian analysis; Markov chain Monte Carlo; Variational inference; Mixture of proposal distributions; Fylogeni; Bayesiansk analys; Markov Chain Monte Carlo; Variationsinferens; Mixturer av förslagsfördelningar;

    Sammanfattning : 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.

  7. 5. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Esther Taiwo Afolabi; [2023]
    Nyckelord :chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Sammanfattning : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. LÄS MER
