After travel through Alaska during the Second World War, in 1947 I went to Barrow with a very lively group of biologists. From their productive research developed the Arctic Research Laboratory. While we examined the rather surpris ingly modest metabolic rates of arctic warmblooded animals in cold, PER SCHO LANDER proposed and then carried out measurements of metabolism of some tropi cal animals in Panama. The differences could be formulated to show the basis of adaptation to arctic cold and to tropical warmth. Imagination and logic were required to formulate the comparison so that it could become a part of science, but the essential measurements were derived from animals and plants in their own arctic and tropical environments. Characteristics that adapt the forms of life to climatic conditions of various environments appear clear in the large dimensions of extremely differing climates. At the time of my arrival in Alaska many of the arctic Eskimos were still largely dependent on natural resources of their immediate and local environment, in which great seasonal changes in temperature and solar radiation appeared as dominant factors. The living environment on which they subsisted was also mar kedly affected by the changes of the seasons, in particular by the change in state of water to ice that terminated summer and by the melting that brought the late transition from winter to summer.

Where and what is the Arctic? What animals live there, and how are they distributed? How do they cope with cold in their austere environment, and how can Arctic mammals survive birth when it is 40 degrees below freezing. How can seals dive to a depth of 1000 metres and stay submerged for more than an hour, and how does complete darkness in winter affect the inhabitants of the high Arctic? This book answers these questions and also gives an introduction to the Arctic. It is based on the author's 40 years of experience in the Arctic, its environment and animal life. As this book contains almost 200 illustrations and deals with the entire Arctic animal kingdom, it will be suitable as a textbook for courses in Arctic biology, and also serve specialists in the field. It is a reference book and a source of information about published original literature.

In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.

Mention the words 'arthropod cuticle' to most biologists and they usually provoke a glazed expression. This is because the cuticle is commonly regarded as an inert substance. It is hoped that this book will dispel this fallacy. The study of cuticle in its proper context now involves many of the wider aspects of biology which are currently in vogue (e. g. how a hormone like ecdyson induces a specific enzyme like dopa decarboxylase; the unsolved major problem of cell gradient and polarity; the involvement of cyclic AMP in hormonal mechanisms; the extra cellular control of cuticular enzymes, of the mechanical proper ties of cuticle structural proteins, and of the orientation of fibrous molecules; and the relation of chromosome puffing to the synthesis of specific proteins). Studies on cuticle demand a variety of techniques, and examples of the following are illustrated in this book (fluorescence, phase contrast, polariza tion and Nomarski interference microscopy; infrared absorp tion; transmission and scanning electron microscopy; autora diography analyzed by electron microscopy; negative staining in the electron microscope; optical diffraction, high angle X-ray diffraction, low angle X -ray diffraction and selected area electron diffraction). I am well aware that the biophysical parts of this book are less incomplete than other aspects. A developmental biologist or a biochemist would have further elaborated other parts ofthe subject matter. Only one previous author, RICHARDS (1951)hasdevoted a book to arthropod cuticle.
