Taking their inspiration from the work of Thomas N. Bisson, to whom the book is dedicated, the contributors to this volume explore the experience of power in medieval Europe: the experience of those who held power, those who helped them wield it, and those who felt its effects. The seventeen essays in the collection, which range geographically from England in the north to Castile in the south, and chronologically from the tenth century to the fourteenth, address a series of specific topics in institutional, social, religious, cultural, and intellectual history. Taken together, they present three distinct ways of discussing power in a medieval historical context: uses of power, relations of power, and discourses of power. The collection thus examines not only the operational and social aspects of power, but also power as a contested category within the medieval world. The Experience of Power suggests new and fruitful ways of understanding and studying power in the Middle Ages.
The hagfishes comprise a uniform group of some 60 species inhabiting the cool or deep parts of the oceans of both hemispheres. They are considered the most primitive representatives of the group of craniate chordates, which - apart from the hagfishes that show no traces of verte brae -includes all vertebrate animals. Consequently the hagfishes have played and still playa central role in discussions concerning the evolution of the vertebrates. Although most of the focus on hagfishes may be the result of their being primitive, it should not be forgotten that, at the same time, they are specialized animals with a unique way of life that is interesting in its own right. It is now more than 30 years since a comprehensive treatise on hagfishes was published. The Biology of Myxine, edited by Alf Brodal and Ragnar Fange (Universitetsforlaget, Oslo, 1963), provided a wealth of information on the biology of hagfishes, and over the years remained a major source of information and inspiration to students of hagfishes.
Before France became France its territories included Occitania, roughly the present-day province of Languedoc. The city of Narbonne was a center of Occitanian commerce and culture during the eleventh and twelfth centuries. For most of the second half of the twelfth century, that city and its environs were ruled by a remarkable woman, Ermengard, who negotiated her city's way through a maze of everchanging dynastic alliances.Fredric L. Cheyette's masterful and beautifully illustrated book is a biography of an extraordinary warrior woman and of a unique, vulnerable, doomed society. Throughout her long reign, viscountess Ermengard roamed Occitania receiving oaths of fidelity, negotiating treatie...
Were aristocratic women in medieval France little more than appendages to patrilineal families, valued as objects of exchange and necessary only for the production of male heirs? Such was the view proposed by the great French historian Georges Duby more than three decades ago and still widely accepted. In Aristocratic Women in Medieval France another model is put forth: women of the landholding elite—from countesses down to the wives of ordinary knights—had considerable rights, and exercised surprising power. The authors of the volume offer five case studies of women from the mid-eleventh through the thirteenth centuries, and from regions as diverse as Blois-Chartres, Champagne, Flanders...
These proceedings present the latest achievements and developments within the scientific community of fur animal research organised by the International Fur Animal Scientific Association (IFASA). The book contains papers on the following topics: nutrition, feeding and management, health and disease, breeding, genetics and reproduction, behaviour and welfare and a theme on 'WelFur for mink and foxes'. The scientific results presented do not only come from traditional mink producing countries, but also from countries with more recent developments in fur animal production. The scientific community in the field of fur animal production is small, but the biologic diversity and thus the need for scientifically based knowledge in this area is similar to, or often exceeds, that of other farm animals. In this book, the most diverse and recent advancements in fur animal production were brought together in order to provide a clear overview for all those involved in the fur animal industry.
How do vertebrates get the oxygen they need, or even manage without it for shorter or longer periods of time? How do they sense oxygen, how do they take it up from water or air, and how do they transport it to their tissues? Respiratory system adaptations allow numerous vertebrates to thrive in extreme environments where oxygen availability is limited or where there is no oxygen at all. Written for students and researchers in comparative physiology, this authoritative summary of vertebrate respiratory physiology begins by exploring the fundamentals of oxygen sensing, uptake and transport in a textbook style. Subsequently, the reader is shown important examples of extreme respiratory performance, like diving and high altitude survival in mammals and birds, air breathing in fish, and those few vertebrates that can survive without any oxygen at all for several months, showing how evolution has solved the problem of life without oxygen.
This volume presents a series of studies by Jacqueline Caille, acknowledged as the leading expert on medieval Narbonne, which chart the development and history of the city from its Roman origins to its decline in the late Middle Ages. They focus on the period of Narbonne's heyday, from the mid-11th to the mid-14th centuries, and a central place is held by Ermengarde, viscountess for half the 12th century, and celebrated figure in the 'world of the troubadours'. The book opens with an important new introductory survey, in English, setting the context for the detailed studies which follow, several of which also appear in English for the first time, and all being updated with additional notes. ...
This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist...
New scientific approaches have dramatically evolved in the decade since The Physiology of Fishes was first published. With the genomic revolution and a heightened understanding of molecular biology, we now have the tools and the knowledge to apply a fresh approach to the study of fishes. Consequently, The Physiology of Fishes, Third Edition is not merely another updating, but rather an entire reworking of the original. To satisfy that need for a fresh approach, the editors have employed a new set of expert contributors steeped in the very latest research; their contemporary perspective pervades the entire text. In addition to new chapters on gas transport, temperature physiology, and stress,...
