Book Description
A primary aim of this catalog is to offer an accounting for each species as originally proposed and for the first usage only of all its name combinations (including valid names, synonymies, and misspellings) that have been published for our area. We follow the policy outlined by the 1985 Code of Zoological Nomenclature for nonmenclatorial proposes that a dissertation for an advanced educational degree is not published unless it satisfies the criteria present in Articles 8 and 9.

Book Description
Volume One of the thoroughly revised and updated guide to the study of biodiversity in insects The second edition of Insect Biodiversity: Science and Society brings together in one comprehensive text contributions from leading scientific experts to assess the influence insects have on humankind and the earth’s fragile ecosystems. Revised and updated, this new edition includes information on the number of substantial changes to entomology and the study of biodiversity. It includes current research on insect groups, classification, regional diversity, and a wide range of concepts and developing methodologies. The authors examine why insect biodiversity matters and how the rapid evolution of insects is affecting us all. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and also examine the consequences that an increased loss of insect species will have on the world. This important text: Explores the rapidly increasing influence on systematics of genomics and next-generation sequencing Includes developments in the use of DNA barcoding in insect systematics and in the broader study of insect biodiversity, including the detection of cryptic species Discusses the advances in information science that influence the increased capability to gather, manipulate, and analyze biodiversity information Comprises scholarly contributions from leading scientists in the field Insect Biodiversity: Science and Society highlights the rapid growth of insect biodiversity research and includes an expanded treatment of the topic that addresses the major insect groups, the zoogeographic regions of biodiversity, and the scope of systematics approaches for handling biodiversity data.

Book Description
Plant breeders have long sought technologies to extend human control over nature. Early in the twentieth century, this led some to experiment with startlingly strange tools like x-ray machines, chromosome-altering chemicals, and radioactive elements. Contemporary reports celebrated these mutation-inducing methods as ways of generating variation in plants on demand. Speeding up evolution, they imagined, would allow breeders to genetically engineer crops and flowers to order. Creating a new food crop or garden flower would soon be as straightforward as innovating any other modern industrial product. In Evolution Made to Order, Helen Anne Curry traces the history of America’s pursuit of tools that could intervene in evolution. An immersive journey through the scientific and social worlds of midcentury genetics and plant breeding and a compelling exploration of American cultures of innovation, Evolution Made to Order provides vital historical context for current worldwide ethical and policy debates over genetic engineering.

Book Description
J. F. Rock hatte eine vielseitige Karriere: Vom Autodidakten entwickelte er sich zur Autorit�t fuer die Botanik Hawaiis; Forschungsreisen in Suedchina brachten reiche Ausbeute an Specimina botanischer (ca. 80000) und ornithologischer Art (ueber 1000) sowie illustrierte Artikel im National Geographic Magazine. In der Folge wurde Rock zum Experten fuer das kleine Volk der Nakhi, deren piktographische Manuskripte (ca. 5000) er sammelte und deren Rituale, Sprache und Geschichte er in umfangreichen Beitr�gen behandelte. Der vorliegende Band gibt ein Schriftenverzeichnis, T�tigkeitsberichte aus Hawaii, Zeitungsberichte ueber Rocks Forschungen, Briefwechsel mit Botanikern und Institutionen (so dem Gray Herbarium) und die umfangreiche Korrespondenz mit dem Harvard-Yenching-Institut, dessen Forschungsmitarbeiter Rock zeitweise war. Die Briefe und Dokumente geben einen lebendigen Eindruck von Rocks vielseitiger wissenschaftlicher T�tigkeit und seiner unternehmenden, eigenwilligen Pers�nlichkeit. "Unterlagen ueber Joseph Rock sind weit verstreut. Dementsprechend ist es schwierig, einen guten �berblick ueber das vorliegende Material zu gewinnen. Aus diesem Grund ist die von Hartmut Walravens hier vorgelegte Materialsammlung fuer eine seri�se Besch�ftigung mit Rock und seinem Lebenswerk von unsch�tzbarer Bedeutung. [�] Zusammenfassend kann festgestellt werden, dass die hier vorliegende Materialsammlung einzigartige Einblicke in die Person des Joseph Rock, seine Entwicklung sowie sein Lebenswerk darstellt. � Eine genauere Auswertung der hier gesammelten Korrespondenzen und Materialien wird wohl weit ueber die Grenzen der Ostasienwissenschaften hinaus wirken."

Book Description
Gardeners of today take for granted the many varieties of geraniums, narcissi, marigolds, roses, and other beloved flowers for their gardens. Few give any thought at all to how this incredible abundance came to be or to the people who spent a good part of their lives creating it. These breeders once had prosperous businesses and were important figures in their communities but are only memories now. They also could be cranky and quirky. In the eighteenth and nineteenth centuries, new and exotic species were arriving in Europe and the United States from all over the world, and these plants often captured the imaginations of the unlikeliest of men, from aristocratic collectors to gruff gardeners who hardly thought of themselves as artists. But whatever their backgrounds, they all shared a quality of mind that led them to ask “What if?” and to use their imagination and skills to answer that question themselves. The newest rose from China was small and light pink, but what if it were larger and came in more colors? Lilac was very nice in its way, but what if its blossoms were double and frilly? While there are many books about plant collectors and explorers, there are none about plant breeders. Drawing from libraries, archives, and the recollections of family members, horticultural historian Judith M. Taylor traces the lives of prominent cultivators in the context of the scientific discoveries and changing tastes of their times. Visions of Loveliness is international in scope, profiling plant breeders from many countries—for example, China and the former East Germany—whose work may be unknown to the Anglophone reader. In addition to chronicling the lives of breeders, the author also includes chapters on the history behind the plants by genus, from shrubs and flowering trees to herbaceous plants.
