Book Description
Els arbres filogenètics ajuden a modelitzar l'evolució de les espècies. En aquests arbres, les fulles representen les espècies actuals, l'arrel representa l'ancestre comú a totes aquestes espècies i cada branca un procés d'especiació. Per a poder inferir les relacions filogenètiques d'un conjunt d'espècies actuals, podem aspirar a conèixer el genoma d'aquestes espècies, tot i que no disposem d'informació del genoma dels ancestres d'aquestes espècies. Existeix un bon nombre de mètodes de reconstrucció filogenètica. En aquest treball, hem implementat i hem analitzat els resultats de 12 mètodes de reconstrucció per quartets. En aquests mètodes, donat un conjunt d'espècies actuals, s'infereixen les relacions filogenètiqes entre tots els subconjunts de 4 espècies dins del conjunt original, i a continuació es combina tota aquesta informació per a construir l'arbre filogenètic resultant. . Tècniques algebraiques desenvolupades recentment permeten usar el rang de certes matrius per a reconstruir l'arbre filogenètic d'un conjunt d'espècies. En aquest projecte s'usaran aquestes tècniques dins de mètodes de reconstrucció filogenètica basats en quartets. S'implementaran diferents mètodes de quartets i es faran tests per avaluar l'eficàcia dels mètodes.

Book Description
Phylogenetics is a topical and growing area of research. Phylogenies (phylogenetic trees and networks) allow biologists to study and graph evolutionary relationships between different species. These are also used to investigate other evolutionary processes?for example, how languages developed or how different strains of a virus (such as HIV or influenza) are related to each other.? This self-contained book addresses the underlying mathematical theory behind the reconstruction and analysis of phylogenies. The theory is grounded in classical concepts from discrete mathematics and probability theory as well as techniques from other branches of mathematics (algebra, topology, differential equations). The biological relevance of the results is highlighted throughout. The author supplies proofs of key classical theorems and includes results not covered in existing books, emphasizes relevant mathematical results derived over the past 20 years, and provides numerous exercises, examples, and figures.?

Book Description
This is the first book on "phylogenetic supertrees", a recent, but controversial development for inferring evolutionary trees. Rather than analyze the combined primary character data directly, supertree construction proceeds by combining the tree topologies derived from those data. This difference in strategy has allowed for the exciting possibility of larger, more complete phylogenies than are otherwise currently possible, with the potential to revolutionize evolutionarily-based research. This book provides a comprehensive look at supertrees, ranging from the methods used to build supertrees to the significance of supertrees to bioinformatic and biological research. Reviews of many the major supertree methods are provided and four new techniques, including a Bayesian implementation of supertrees, are described for the first time. The far-reaching impact of supertrees on biological research is highlighted both in general terms and through specific examples from diverse clades such as flowering plants, even-toed ungulates, and primates. The book also critically examines the many outstanding challenges and problem areas for this relatively new field, showing the way for supertree construction in the age of genomics. Interdisciplinary contributions from the majority of the leading authorities on supertree construction in all areas of the bioinformatic community (biology, computer sciences, and mathematics) will ensure that this book is a valuable reference with wide appeal to anyone interested in phylogenetic inference.

Book Description
Researchers interested in the history of the Indo-European family of languages have used a variety of methods to estimate the phylogeny of the family, and have obtained widely differing results. In this paper we explore the reconstructions of the Indo-European phylogeny obtained by using the major phylogeny estimation procedures on an existing database of 336 characters (including lexical, phonological, and morphological characters) for 24 Indo-European languages. Our study finds that the different methods agree in part, but that there are also several striking differences. We discuss the reasons for these differences, and make proposals with respect to phylogenetic reconstruction in historical linguistics.

Book Description
This book integrates a wide variety of data analysis methods into a single and flexible interface: the R language. The book starts with a presentation of different R packages and gives a short introduction to R for phylogeneticists unfamiliar with this language. The basic phylogenetic topics are covered. The chapter on tree drawing uses R's powerful graphical environment. A section deals with the analysis of diversification with phylogenies, one of the author's favorite research topics. The last chapter is devoted to the development of phylogenetic methods with R and interfaces with other languages (C and C++). Some exercises conclude these chapters.
