  1. 1. Bayesian Phylogenetic Inference : Estimating Diversification Rates from Reconstructed Phylogenies

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

    Abstract : 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. READ MORE

  2. 2. Nucleotide Substitution Patterns in Vertebrate Genomes

    Author : Carina Farah Mugal; Hans Ellegren; Ziheng Yang; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; nucleotide substitutions; mutation rate variation; strand asymmetries; CpG effect; GC-biased gene conversion; codon evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : The rates and patterns at which nucleotide substitutions occur vary significantly across the genome sequence of vertebrates. A prominent example is the difference in the rate of evolution of functional sequences versus nonfunctional (neutrally evolving) sequences, which is explained by the influence of natural selection on functional sequences.
