Download or read book Species Tree Inference written by Laura Kubatko and published by Princeton University Press. This book was released on 2023-03-14 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Inferring evolutionary relationships among a collection of organisms -- that is, their relationship to each other on the tree of life -- remains a central focus of much of evolutionary biology as these relationships provide the background for key hypotheses. For example, support for different hypotheses about early animal evolution are contingent upon the phylogenetic relationships among the earliest animal lineages. Within the last 20 years, the field of phylogenetics has grown rapidly, both in the quantity of data available for inference and in the number of methods available for phylogenetic estimation. The authors' first book, "Estimating Species Trees: Practical and Theoretical Aspects", published in 2010, gave an overview of the state of phylogenetic practice for analyzing data at the time, but much has changed since then. The goal of this book is to serve as an updated reference on current methods within the field. The book is organized in three sections, the first of which provides an overview of the analytical and methodological developments of species tree inference. Section two focuses on empirical inference. Section three explores various applications of species trees in evolutionary biology. The combination of theoretical and empirical approaches is meant to provide readers with a level of knowledge of both the advances and limitations of species-tree inference that can help researchers in applying the methods, while also inspiring future advances among those researchers with an interest in methodological development"--

Download or read book Biogeology written by Bernard Michaux and published by CRC Press. This book was released on 2019-07-02 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This detailed exposition gives background and context to how modern biogeography has got to where it is now. For biogeographers and other researchers interested in biodiversity and the evolution of life on islands, Biogeology: Evolution in a Changing Landscape provides an overview of a large swathe of the globe encompassing Wallacea and the western Pacific. The book contains the full text of the original article explored in each chapter, presented as it appeared on publication. Key features: Holistic treatment, collecting together a series of important biogeographical papers into a single volume Authored by an expert who has spent nearly three decades actively involved in biogeography Describes and interprets a region of exceptional biodiversity and extreme endemism The only book to provide an integrated treatment of Wallacea, Melanesia, New Zealand, the New Zealand Subantarctic Islands and Antarctica Offers a critique of fashionable neo-dispersalist arguments, showing how these still suffer from the same weaknesses of the original Darwinian formulation. The chapters also include analysis of many major theoretical and philosophical issues of modern biogeographic theory, so that those interested in a more philosophical approach will find the book stimulating and thought-provoking.
Download or read book Ancient DNA written by Bernd Herrmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ancient DNA refers to DNA which can be recovered and analyzed from clinical, museum, archaeological and paleontological specimens. Ancient DNA ranges in age from less than 100 years to tens of millions of years. The study of ancient DNA is a young field, but it has been revolutionized by the application of polymerase chain reaction technology, and interest is growing very rapidly. Fields as diverse as evolution, anthropology, medicine, agriculture, and even law enforcement have quickly found applications in the recovery of ancient DNA. This book contains contributions from many of the "first generation" researchers who pioneered the development and application of ancient DNA methods. Their chapters present the protocols and precautions which have resulted in the remarkable results obtained in recent years. The range of subjects reflects the wide diversity of applications that are emerging in research on ancient DNA, including the study of DNA to analyze kinship, recovery of DNA from organisms trapped in amber, ancient DNA from human remains preserved in a variety of locations and conditions, DNA recovered from herbarium and museum specimens, and DNA isolated from ancient plant seeds or compression fossils. Ancient DNA will serve as a valuable source of information, ideas, and protocols for anyone interested in this extraordinary field.

This book was released on 2012-10-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: (LIMITED EDITION- ONLY PHOTOSTAT COPY AVAILABLE) Livestock farming is raising animals for food or to sell and is very well planned. Livestock animals play an important role in rural economic development. Some of these animals include cattle or dairy cows, chickens, goats, pigs, sheep, etc. India is the second largest market worldwide and aquaculture contributes 1.5 per cent to the gross domestic product (GDP), Livestock gives us meat, eggs and milk apart from using the skins and hair of some animals for blankets, clothing, and brushes. Manure from these animals will be used to make plants grow better. Poultry farming is raising chickens for meat or eggs and India is the fourth largest market worldwide in poultry. Dairy farms are farms where cows are raised to make milk and milk products like cheese, ice cream, butter and whipping cream. Today, poultry raising and dairy farming are big business. India has a high potential in the sheep industry and also a very diverse genetic resources through which, if scientifically bred the production in sheep industry can be enhanced. India is endowed with livestock resources of vast genetic diversity and accounts for about 11 percent of the world livestock population. The country boasts of 55 per cent of the world buffalo population, 20 per cent of the goat population and 16 per cent of the cattle population in the world. India has the second rank with respect to goat and sheep world population. Indian exports of live animals like sheep and goat over the years continued to dominate with a registered growth of 9.98 per cent over the last three years. The government is making concerted efforts to tap the vast export potential of the country huge livestock population. The aim of this book is to provide some profitable farming & Allied projects for you. You can invest in any farming and allied projects such as: dairy farm to produce milk, poultry processing plant, poultry feed, egg powder, shrimp farming, goat & sheep farming, pig farming, angora rabbit farming, pig meat processing. This book is very useful for one who wants to enter in this field, for businessmen, industrialists and all relevant people.
Download or read book Avian Molecular Evolution and Systematics written by David P. Mindell and published by Academic Press. This book was released on 1997-05-13 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of DNA and other biological macromolecules has revolutionized systematic studies of evolutionary history. Methods that use sequences of nucleotides and amino acids are now routinely used as data for addressing evolutionary questions that, although not new questions, have defied description and analysis. The world-renowned contributors use these new methods to unravel particular aspects of the evolutionary history of birds. Avian Molecular Evolution and Systematics presents an overview of the theory and application of molecular systematics, focusing on the phylogeny and evolutionary biology of birds. New, developing areas in the phylogeny of birds at multiple taxonomic areas are covered, as well as methods of analysis for molecular data, evolutionary genetics within and between bird populations, and the application of molecular-based phylogenies to broader questions of evolution. - Contains authoritative contributions from leading researchers - Discusses the utility of different molecular markers for questions of avian evolution, involving populations and higher-level taxa - Applies molecular-based phylogenies of birds and molecular population genetics data to broad questions of organismal and molecular evolution. - Compares and contrasts molecular and morphological data sets
