Avian Biology, Volume II is a collection of papers that deals with the biology of birds such as their integumentary and respiratory systems. One paper describes the integument of birds that includes the skin, feathers, pterylosis, skin muscles, and other integumentary derivatives such as beaks, comb, claws, and spurs. The book explains the process of molting and the different generations of feathers; such molting is dependent on the wear and tear of the plumage, as well as hormonal changes. One author compares the blood vascular system of birds and mammals, and then gives a detailed description of avian hematology. Other papers deal with the respiratory functions, digestive system, and the nutritional needs of birds. Of interest is one author's description of the production of nutritive fluids, holocrine, which is secreted for the young. This secreted fluid contains about 23 percent protein, 10 percent fat, and no sugar. Unlike mammalian milk, it also contains cells. Another paper examines the intermediary metabolism of birds and the climatic effects on metabolism. This book is suitable for bird enthusiasts, zoologists, and avian biologists.

Opening Speech of the ICEDIVE 84 Conference by His Royal Highness Prince Bertil of Sweden I am very pleased to be invited to open the International Conference ICEDIVE 84, dealing with medical and technical problems of diving and related underwater activities in arctic conditions. Until recent times, the arctic was considered astrange and remote area of minor importance. However, in a world with diminishing natural resources, arctic areas have become a region of global importance because of their enormous resources and strategie position. Certain experts believe that more than 50% of oil reserves are "sleeping" in these northern areas which are cold, harsh and hostile to man. Operations in arctic areas are extremely difficult, expensive, and demand high levels of technical, scientific and physiological achievement. One should recall for example, that Alaskan oil investment onIy became economically viable after the 1973-1974 price explosion. Recent political/military troubles in the Gulf have increased interest in the development of polar resources. This conference is unique as it is the first time that medical and technical specialists interested in the problem of diving in arctic conditions have met in an international forum. Development of the arctic resources is a matter of international urgency, and it pleases me that scientists from the USA, Canada, the USSR, Australia and Europe have gathered here in Stockholm to present their experience and to discuss problems in this field.

A Handbook on Biotelemetry and Radio Tracking presents the proceedings of an International Conference on Telemetry and Radio Tracking in Biology and Medicine, held in The University of Oxford, Oxford, U.K. on March 20–22, 1979. This book illustrates the advances connected with every aspect of biotelemetry and radio tracking. Organized into five parts encompassing 101 chapters, this compilation of papers begins with an overview of the method that allows assessment or control of biological parameters from animals, subjects, and patients with comparatively little disturbance and restraint. This text then examines radio telemetry as a system for telemetry or communications over great distances. Other chapters consider better transmitter design and construction of radio tracking. This book discusses as well telemetric measurements of hemodynamic response to driving in coronary patients. The final chapter deals with the study of the coastal movements of Atlantic salmon tagged with ultrasonic transmitters. This book is a valuable resource for biological researchers and ecologists.

Animal Models and Hypoxia consists of proceedings from an international symposium. The text discusses the developments made on the study of brain metabolism. An article about the regional utilization of glucose in the brain of mammals is presented. There is also a section that reviews the energy metabolism in the nervous system of insects. The topics covered includes the role of sympathetic innervation in the regulation of cerebral blood flow during hypercapnia, the comparative aspects of energy metabolism in non-mammalian brains under normoxic and hypoxic conditions, and an anoxic rat model. A method developed to gauge the rates of glucose utilization in the central nervous system is evaluated. This method is effective in mapping the functional neural pathways base on stimulated metabolic responses. Factors that contribute to the development of gerontopsychiatric disorders in men are reviewed. The book will provide useful information to doctors, veterinarians, neurologists, students, and researchers in the field of neurology.

This volume is one of those published from the proceedings of the invited lectures to the First International Congress of Comparative Physiology and Biochemistry I organized at Liege (Belgium) in August 1984 under the auspices of the Section of Comparative Physiology and Biochemistry of the International Union of Biological Sciences. In a general foreword to these different volumes, it seems to me appropriate to consider briefly what may be the comparative approach. Living organisms, beyond the diversity of their morphological forms, have evolved a widespread range of basic solutions to cope with the different problems, both organisma1 and environmenta1 with which they are faced. Soon after the turn of the century, some biologists realized that these solutions can be best comprehended in the frame work of a comparative approach integrating results of physiologica1 and biochemica1 studies done at the organismic, cellular and molecular levels. The development of this approach amongst both physiologists and biochemists remained, however, extremely slow until recently.
