Book Description
In this book we bring together the most up-to-date information on developments, both basic and applied, that already have or are expected to impact the field of ornamental breeding. These include classical and molecular techniques, traditional and high-throughput approaches and future trends. Since not only professional scientists, but also thousands of future scientists/students as well as amateur breeders around the world contribute heavily to the field of ornamental breeding, an introductory section dealing with the basics of molecular and classical genetics and the evolution of floral diversity is included. This should enable the reader to bridge the gap between traditional and molecular genetics. Classical approaches to the creation/selection of genetic variability, including mutation and tissue culture-aided breeding, are presented. Processes affecting ornamental and agronomic traits at the molecular level are delineated, along with an in-depth analysis of developments in the protection of intellectual property rights. The thoughts and strategies of molecular and classical geneticists, which are not always complementary or even compatible, are presented side by side in this book, and will serve to spark the imaginations of breeders as well as students entering the exciting world of state-of-the-art ornamentals.

Book Description
In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.

Book Description
Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.

Book Description
Like music, art is a universal language. Although looking at works of art is a pleasurable enough experience, to appreciate them fully requires certain skills and knowledge." --Carol Strickland, from the introduction to The Annotated Mona Lisa: A Crash Course in Art History from Prehistoric to Post-Modern * This heavily illustrated crash course in art history is revised and updated. This second edition of Carol Strickland's The Annotated Mona Lisa: A Crash Course in Art History from Prehistoric to Post-Modern offers an illustrated tutorial of prehistoric to post-modern art from cave paintings to video art installations to digital and Internet media. * Featuring succinct page-length essays, instructive sidebars, and more than 300 photographs, The Annotated Mona Lisa: A Crash Course in Art History from Prehistoric to Post-Modern takes art history out of the realm of dreary textbooks, demystifies jargon and theory, and makes art accessible-even at a cursory reading. * From Stonehenge to the Guggenheim and from Holbein to Warhol, more than 25,000 years of art is distilled into five sections covering a little more than 200 pages.

Book Description
“One of the most profound and illuminating studies of this century to have been published in recent decades.”—John Gray, New York Times Book Review Hailed as “a magisterial critique of top-down social planning” by the New York Times, this essential work analyzes disasters from Russia to Tanzania to uncover why states so often fail—sometimes catastrophically—in grand efforts to engineer their society or their environment, and uncovers the conditions common to all such planning disasters. “Beautifully written, this book calls into sharp relief the nature of the world we now inhabit.”—New Yorker “A tour de force.”— Charles Tilly, Columbia University
