Properties of phylogenetic trees generated by Yule-type speciation models.
We investigate some discrete structural properties of evolutionary trees generated under simple null models of speciation, such as the Yule model. These models have been used as priors in Bayesian approaches to phylogenetic analysis, and also to test hypotheses concerning the speciation process. In this paper we describe new results for three properties of trees generated under such models. Fir...
متن کاملStochastic Models for Speciation Events in Phylogenetic trees
Hiermit erkläre ich, dass ich die Diplomarbeit selbständig angefertigt und nur die angegebenen Quellen und Hilfsmittel verwendet habe. Acknowledgements First and foremost, I would like to thank my supervisor Mike Steel for making it possible for me to come to New Zealand, for the great support throughout my stay, for suggesting great problems to work on and for very helpful discussions and advi...
متن کاملUsing Treemaps to Visualize Phylogenetic Trees
Over recent years the field of phylogenetics has witnessed significant algorithmic and technical progress. A new class of efficient phylogeny programs allows for computation of large evolutionary trees comprising 500–1.000 organisms within a couple of hours on a single CPU under elaborate optimization criteria. However, it is difficult to extract the valuable information contained in those larg...
متن کاملUsing Clustering Trees for Learning Phylogenetic Trees
This paper presents ongoing work on an application of machine learning in phylogenetic analysis, which is the study of evolutionary relatedness among various groups of organisms. Insights in evolutionary relationships are important because they can help to determine the function of uncharacterized genes and they can be used to predict future variants of fast-growing viruses. More precisely, we ...
متن کاملPhylogenetic estimates of speciation and extinction rates for testing ecological and evolutionary hypotheses.
Phylogenies are used to estimate rates of speciation and extinction, reconstruct historical diversification scenarios, and link these to ecological and evolutionary factors, such as climate or organismal traits. Recent models can now estimate the effects of binary, multistate, continuous, and biogeographic characters on diversification rates. Others test for diversity dependence (DD) in speciat...
