The second volume of the book series describes in a compact form the colour canaries and the fascinating breeding of carduelid hybrids. The author gives an overview of the history of genetics and the mechanisms of plumage colouration. The latest scientific findings are included. All currently bred and internationally recognised varieties of colour canaries are described in words and pictures. New are the colour descriptions according to the RAL colour system. Furthermore, there are valuable hints on breeding hybrids between canaries and other carduelids or between different carduelid species. Many mating is discussed and presented with pictures. These topics are rounded off with the necessary hints for participation in exhibitions and bird evaluations. In the appendix you will find a whole series of tables for the most diverse mating between individual canary colours.
The third volume of the book series describes in a compact form 59 posture canary breeds from all over the world in words and pictures. The special body shapes or plumage of these canaries are an expression of the breeder's will and fascinate many bird lovers worldwide. In the general part of the book, the ethical responsibility and animal welfare in bird breeding is explained, the special anato-my and inheritance mechanisms are described and general hints for breeding are given. In the special part, 59 posture canaries are presented. The history and development of each breed plays a special role, as some were created almost 200 years ago, others in more recent times. The description of the standard characteristics and peculiarities in breeding complete the individual breed descriptions. This volume is rounded off with a list of all technical terms used in the three volumes of this compendium.
With this volume, the well-known author begins a three-part book series that will cover all breeding directions of canary breeding in a compact form. In volume 1, the interesting history of the Canary's development into a domestic bird is examined from partly new aspects. The book contains tried and tested advice on keeping, caring for and breeding canaries in a manner appropriate to their species, as well as on a balanced, largely natural diet. In addition to an introduction to the anatomy of birds, embryonic development and feather structure, the volume also deals with compactly compiled advice on the treatment of diseases and parasite infestations. The special section of the book explains the four most important song canary breeds and their songs. In addition, there are valuable tips on breeding the song-colour and song-posture canaries. This part of the book is rounded off with tips on breeding and training the song canaries.
The current popularity of such phrases as "information age" and 'information society" suggests thatlinks between information,communication, and: behavior have become closer and more complex in a technology-dominated culture. Social scientists have adopted an integrated approach to these concepts, opening up new theoretical perspectives on the media, social psychology, personal relationships, group process, international diplomacy, and consumer behavior. Between Communication and Information maps out a richly interdisciplinary approach to this development, offering innovative research and advancing our understanding of integrative frameworks.This fourth volume in the series reflects recently ...
Foremost scholars explore new directions in communication research in the light of social, economic, and technological changes in recent years. They analyze differing perspectives historically, problems and opportunities in terms of information flows and filters, and new public policy and social issues and challenges. They raise major questions about future needs and trends. This interdisciplinary study delves into a number of basic concerns, such as how public agendas are formed, how shifting groups in society interpret messages differently, and how technology has changed profoundly the ways in which we communicate in the world today. This overview of the state of communication research is designed for scholars, professionals, and for student use in research methods courses.
The rapid development of the sulfur-nitrogen chemistry during the last decades has yielded new compounds in such an amount that the edition of volumes dedicated to sulfur-nitrogen compounds is justified. Cyclic S-N compounds with sulfur of formal oxidation number IV containing C atoms, C and O atoms, or C and P atoms in the six-, seven-, eight-, or nine-membered ring systems are described. This volume concludes the description of cyclic compounds with Sulfur or Oxidation Number IV. In addition to the formula index, a ring index for parts 3 and 4 of S-N compounds facilitates finding specific ring systems, and also illustrates the puzzling manifold of the described ring system.
