Ducks, Geese, and Swans of the World by Paul A. Johnsgard Pdf
The primary purpose of this book is to provide information on each of the species of the waterfowl family in a standardized format and easily accessible manner.
A summary of information on 154 species of duck, geese and swans of the world intended as an identification manual for the wildfowl enthusiast that goes beyond a regional basis and is light enough to be used as a handy reference book in the field. Wildfowl is a unique combination of scientifically accurate information compressed into an easy-to-use format which has been planned to give anyone a greater understanding of the lives of this fascinating group of birds. The 47 superb colour plates form the backbone of the book, each plate being accompanied by an informative caption page summarising the criteria required to identify, and in many cases, to age and sex each species, along with an easy-to-use cross reference system to the main body of text. The text not only clarifies identification techniques but fully discusses problematic plumages in detail as well as providing a summary on world distribution and status complemented by clear distribution maps.
This beautifully illustrated book with colour photographs and original paintings, maps and diagrams, presents an up-to-date and comprehensive survey of the natural history of birds. It will provide readers with a better understanding and appreciation of the world of birds and the preservation of their habitats.
Avian Molecular Evolution and Systematics by David P. Mindell Pdf
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
