  1. 6. Molecular Phylogenetics of Mammals

    Författare :Morgan Kullberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; EST; divergence times; phylogenomics; phylogenetic reconstruction; Mammals; Eutheria; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : In this thesis, the phylogenetic relationships of the Mammalia have been studied at various levels. Different sources of genetic information have been evaluated and used as phylogenetic markers. These include the well-known mitochondrial genome, cDNA from housekeeping genes and expressed sequence tags from nuclear genes. LÄS MER

  3. 7. Bayesian Phylogenetic Inference : Estimating Diversification Rates from Reconstructed Phylogenies

    Författare :Sebastian Höhna; Tom Britton; Fredrik Ronquist; Ziheng Yang; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Bayesian inference; Graphical Models; Birth-Death Process; Diversification; matematisk statistik; Mathematical Statistics;

    Sammanfattning : Phylogenetics is the study of the evolutionary relationship between species. Inference of phylogeny relies heavily on statistical models that have been extended and refined tremendously over the past years into very complex hierarchical models. LÄS MER

  4. 8. Computational Problems in Modeling Evolution and Inferring Gene Families

    Författare :Mehmood Alam Khan; Lars Arvestad; Jens Lagergren; Christophe Dessimoz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Phylogenetics; Lateral Gene Transfer; Gene Families; Clustering; Datalogi; Computer Science;

    Sammanfattning : Over the last few decades, phylogenetics has emerged as a very promising field, facilitating a comparative framework to explain the genetic relationships among all the living organisms on earth. These genetic relationships are typically represented by a bifurcating phylogenetic tree — the tree of life. LÄS MER

  5. 9. Comparative Seed Morphology and Phylogenetics : Case Studies in Basal Angiosperms (ANITA) and Asterids (Lysimachia, Ericales)

    Författare :Il-Chan Oh; Mats Thulin; Arne A. Anderberg; Bertil Ståhl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; systematisk botanik; Systematic Botany;

    Sammanfattning : The first half of the thesis deals with the seed morphology of members of the ANITA grade at the base of the angiosperm phylogeny (Amborella, Nymphaeales, Illiciales, Trimeniaceae, and Austrobaileyaceae), especially Illiciaceae and Schisandraceae. Seed characters support a major division between the New World and Old World species of Illicium. LÄS MER
