The opportunity to prepare a second edition of a book that was originally written 30 years ago has provided me with both a challenge and a source of pleas­ over ure; the former as it needed to be spatially constrained within its original limits.  Meer

Biological effects of magnetic fields have been studied in many animals and plants. The magnetic fields were of a wide intensity range and, as alternating fields, of a wide frequency range and of a variety of impulse shapes.  Meer

This work documents various studies on hearing in marsupials and relates this information to their vocal behaviour. The organization of the brain auditory pathways of marsupials is compared with those of eutherian mammals and related to the structure of the periphery.  Meer

The factors which set the metabolic potentials of animals have been decisive determinants of the constructions of the gas exchangers. This manual takes a look at the designs of gas exchangers, including gas exchange media, respiratory states and environments, water breathing and bimodal breathing.  Meer

The opportunity to prepare a second edition of a book that was originally written 30 years ago has provided me with both a challenge and a source of pleas­ over ure; the former as it needed to be spatially constrained within its original limits.  Meer

In 1954, when I obtained my B. Sc. (Honours School) degree in Zoology, I was asked by my advisor, the late Professor Vishwa Nath, to make comparative cytological studies of oogenesis in birds for my M.  Meer

I had the good fortune to first meet Gerald Kuchling in 1985 when attending a conference held at the CNRS research centre, the Centre d'Etudes Biologiques des Animaux Sauvages (CEBAS), which is a wonderful scientific field station tucked away in the Foret de Chize, not far from the southwest town of Niort in France.  Meer

The intention of this book is to offer a comprehensive description and discussion of autonomic nerve function in the vertebrates from several points of view.  Meer

Chance Favors Only the Prepared Mind How does a scientist go about the task of pushing back the curtains of the unknown? Certainly the romance of tackling the mysteries of nature provides the motivation, for who would not be inspired by the remarkable life history of this romantic beast, the salmon.  Meer

Fish migration is important and spectacular. Migratory fish gather energy in one portion of the environment and transport it to other areas, where it often becomes available to humans or to other elements in the ecosystem.  Meer

This book reviews the respiratory function of vertebrate red cells. I have defined the phrase "respiratory function" broadly to include, in addition to the actual oxygen and carbon dioxide transport, erythropoiesis, haemoglobin synthesis, red cell structure, the deformability of red cells in circulation, ion and substrate transport across the cell membrane, cellular metabolism, and control of cellular volume and pH.  Meer

In retrospect, the range of topics covered in this monograph, although forming a coherent ensemble, is so extensive that a detailed discussion could easily extend to three or four times the current length.  Meer

As the title indicates, the theme of this book is the functions of biochromes in animals. Recent works on zoochromes, such as those of D. L. Fox (1953), H.  Meer

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.  Meer

The brain of an echo locating bat is devoted, in large part, to analyzing sound and conducting behavior in a world of sounds and echoes. This monograph is about analysis of sound in the brainstem of echolocating bats and concerns the relationship between brain structure and brain function.  Meer

Some fishes test their environment by generating electric fields outside their bodies (man's first contact with electricity). To send and receive electric signals, one's own or those from a neighbor, is the basis of some bony fishes' unusual sensory capacities that enable them to lead a secret, nocturnal life.  Meer

This book has been written mostly within sight of wild African ungulates, at the research center in Tsavo East National Park, V oi, Kenya. While this had many positive aspects, there were also a few drawbacks.  Meer

Interest in comparative acid-base physiology has considerably grown during last decades even in the absence of major technical or conceptual advances.  Meer

Peritrophic membranes are secretion products of the midgut. For long they have been related only to insects, but they occur widely in the animal kingdom.  Meer

This volume emphasizes the comparative approach to under­ standing vertebrate renal function. I am convinced that this approach is of particular value in understanding both the details of renal function at the cellular and subcellular levels and the renal role in regulating fluid volumes and solute concentrations.  Meer
