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

    University essay from KTH/Matematisk statistik

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

    Abstract : 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.

  3. 2. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species

    University essay from KTH/Matematisk statistik

    Author : Elin Eliasson; Rebecka Haraldsson; [2023]
    Keywords : Phylogenetics; Tree reconstruction; COI barcoding; General Time Reversible Model; K80 Model; Evolution; Butterflies; Fylogenetik; Rekonstruktion av träd; COI barcoding; General Time Reversible modell; K80 modell; Evolution; Fjärilar;

    Abstract : 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. 4. Phylogenomics of Ascetosporea

    University essay from Uppsala universitet/Systematisk biologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Harshal Kunal Bhawe; [2022]
    Keywords : phylogenetics; ascetosporea; bioinformatics; mussel;

    Abstract : Ascetosporea is a class of poorly studied unicellular eukaryotes that function as parasites of marine invertebrates. These parasites cause mass mortality events in aquaculture species such as oysters and mussels. READ MORE

  6. 5. Phylogenetic analysis of secretion systems in Francisellaceae and Legionellales : Investigating events of intracellularization

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Karl Nyrén; [2021]
    Keywords : Metagenomics; Phylogenetics; Secretion systems; Francisellaceae; Legionellales; Host-adaptation; Evolution; Intacellularization;

    Abstract : Host-adapted bacteria are pathogens that, through evolutionary time and host-adaptive events, acquired the ability to manipulate hosts into assisting their own reproduction and spread. Through these host-adaptive events, free-living pathogens may be rendered unable to reproduce without their host, which is an irreversible step in evolution. READ MORE
