The name DGGTB (Deutsche Gesellschaft für Geschichte und Theorie der Biologie; German Society for the History and Theory of Biology) refl ects recent history as well as German tradition. The Society is a relatively late addition to a series of German societies of science and medicine that began with the »Deutsche Gesellschaft für Geschichte der Medizin und der Naturwissenschaften«, founded in 1910 by Leipzig University's Karl Sudhoff (1853-1938), who wrote: »We want to establish a ,German' society in order to gather German-speaking historians together in our special disciplines so that they form the core of an international society«. Yet Sudhoff, at this time of burgeoning academic internationalism, was »quite willing« to accommodate the wishes of a number of founding members and »drop the word German in the title of the Society and have it merge with an international society«. The founding and naming of the Society at that time derived from a specific set of historical circumstances, and the same was true some 80 years later when in 1991, in the wake of German reunification, the »Deutsche Gesellschaft für Geschichte und Theorie der Biologie« was founded. From the start, the Society has been committed to bringing studies in the history and philosophy of biology to a wide audience, using for this purpose its Jahrbuch für Geschichte und Theorie der Biologie. Parallel to the Jahrbuch, the Verhandlungen zur Geschichte und Theorie der Biologie has become the by now traditional medium for the publication of papers delivered at the Society`s annual meetings. In 2005 the Jahrbuch was renamed Annals of the History and Philosophy of Biology, reflecting the Society's internationalist aspirations in addressing comparative biology as a subject of historical and philosophical studies.

Armed with razor-sharp teeth and capable of drinking many times its volume of blood, the leech is an unlikely cure for ill health. Yet that is exactly the role this worm-like parasite has played in both Western and Eastern medicine throughout history. In this book, Robert G. W. Kirk and Neil Pemberton explore how the leech surfaces in radically different spheres. The ancients used them in humeral medicine to bring the four humors of the body—blood, phlegm, and black and yellow bile—back into balance. Today, leeches are used in plastic and reconstructive surgery to help reattach severed limbs and remove pools of blood before it kills tissue. Leeches have also been used in a nineteenth-century meteorological barometer and a twentieth-century biomedical tool that helped win a Nobel Prize. Kirk and Pemberton also reveal the dark side of leeches as they are portrayed in fiction, film, and popular culture. From Bram Stoker’s Dracula to a video game player’s nemesis, the leech is used to represent the fears of science run amok. Leech shines new light on one of humanity’s most enduring and unlikely companions.

This comprehensive, authoritative and up-to-date work provides the definitive overview of marine parasites worldwide. It is an invaluable reference for students and researchers in parasitology and marine biology and will also be of interest to ecologists, aquaculturists and invertebrate biologists. Initial chapters review the diversity and basic biology of the different groups of marine parasites, discussing their morphology, life cycles, infection mechanisms and effects on hosts. The ecology and importance of marine parasites are discussed in the second part of the book, where contributions investigate behavioural and ecological aspects of parasitism and discuss the evolution and zoogeography of marine parasites. In addition, the economic, environmental and medical significance of these organisms is outlined, particularly their importance in aquaculture and their effects on marine mammals and birds. Written by an international team of contributors, the emphasis is on a thorough grounding in marine parasitology combined with reviews of novel concepts and cutting-edge research.

Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.

An examination of nature's extraordinary biological diversity and the human activities that threaten it. Life on Earth: An Encyclopedia of Biodiversity, Ecology, and Evolution tackles the critical issue for humanity in the 21st century—our ever more menacing impact on the environment. This two-volume, illustrated set, edited by American Museum of Natural History curator Niles Eldredge, begins with biodiversity, the complex planetary web of life that has emerged through three billion years of evolution. How does it work? And why is its continued health critical to the planet and to ourselves? More than 50 top scholars examine every form of life from amoebae to elephants, from plankton to whales. But Life on Earth is more than a catalog of species. An A–Z survey explores the myriad ways humanity is diminishing that biodiversity, from industrialization to natural habitat destruction, from overpopulation in the developing world to an unsustainable consumer lifestyle in the West. Life on Earth is the essential reference work for anyone curious about our planet's extraordinary diversity of life and the unprecedented threats it faces.

“A witty, scientifically accurate, and often intensely creepy exploration of sanguivorous creatures.”—San Francisco Chronicle “Bill Schutt turns whatever fear and disgust you may feel towards nature’s vampires into a healthy respect for evolution’s power to fill every conceivable niche.”—Carl Zimmer, author of Parasite Rex and Microcosm: E. coli and the New Science of Life For centuries, blood feeders have inhabited our nightmares and horror stories, as well as the shadowy realms of scientific knowledge. In Dark Banquet, zoologist Bill Schutt takes us on a fascinating voyage into the world of some of nature’s strangest creatures—the sanguivores. Using a sharp eye and mordant wit, Schutt makes a remarkably persuasive case that blood feeders, from bats to bedbugs, are as deserving of our curiosity as warmer and fuzzier species are—and that many of them are even worthy of conservation. Examining the substance that sustains nature’s vampires, Schutt reveals just how little we actually knew about blood until well into the twentieth century. We revisit George Washington on his deathbed to learn how ideas about blood and the supposedly therapeutic value of bloodletting, first devised by the ancient Egyptians and Greeks, survived into relatively modern times. Dark Banquet details our dangerous and sometimes deadly encounters with ticks, chiggers, and mites (the latter implicated in Colony Collapse Disorder—currently devastating honey bees worldwide). Then there are the truly weird—vampire finches. And if you thought piranha were scary, some people believe that the candiru (or willy fish) is the best reason to avoid swimming in the Amazon. Enlightening and alarming, Dark Banquet peers into a part of the natural world to which we are, through our blood, inextricably linked.

Written by experts actively working in the area, this book provides a review of the major diseases of fish caused by protozoan and metazoan parasites. The new edition has been thoroughly updated since publication of the first edition in 1995. It covers recent advances in the understanding of fish diseases including the improvement of diagnostic techniques and understanding of phylogenetic relationships stemming from the application of molecular techniques. The book also contains more detailed information on pathogens that cause amoebiasis.
