This is Robert Fried's third book on the crucial role of breathing and hyperventilation in our emotional and physical health. The first, The Hyperventilation Syndrome (1987), was a scholarly monograph, and the second, The Breath Connection (1990a), was a popular version for the lay reader. This book combines the best features of both and extends Dr. Fried's seminal work to protocols for clinical psychophysiology and psy chiatry. Hoping to avoid misunderstanding, he has taken systematic care to introduce relevant electrical, physiological, and psychological concepts in operational language for the widest possible professional audience. Any clinician not thoroughly experienced in respiratory psycho physiology and biofeedback will leave these pages with profound new insight and direction into an aspect of our liveswhich we innocently take for granted as "common sense"-the role of breathing in health and illness. Einstein viewed such common sense as "that set of prejudices we acquired prior to the age of eighteen." I am impressed that Dr. Fried mirrors Einstein's uncanny genius in not accepting the obvious breathing is not "common sense" but, rather, is a pivotal psycho physiological mechanism underlying all aspects of life.

"Physiology," which is the study of the function of cells, organs, and organisms, derives from the Latin physiologia, which in turn comes from the Greek physi- or physio-, a prefix meaning natural, and logos, meaning reason or thought. Thus physiology suggests natural science and is now a branch of biology dealing with processes and activities that are characteristic of living things. "Physicochemical" relates to physical and chemical properties, and "Environmental" refers to topics such as solar irradiation and wind. "Plant" indicates the main focus of this book, but the approach, equations developed, and appendices apply equalIy welI to animaIs and other organisms. We wilI specificalIy consider water relations, solute transport, photosynthesis, transpiration, respiration, and environmental interactions. A physiologist endeavors to understand such topics in physical and chemical terms; accurate models can then be constructed and responses to the internal and the external environment can be predicted. Elementary chemistry, physics, and mathematics are used to develop concepts that are key to under-standing biology -the intent is to provide a rigorous development, not a compendium of facts. References provide further details, although in some cases the enunciated principIes carry the reader to the forefront of current research. Calculations are used to indicate the physiological consequences of the various equations, and problems at the end of chapters provide further such exercises. Solutions to alI of the problems are provided, and the appendixes have a large tist of values for constants and conversion factors at various temperatures.

This book introduces a holistic synthesis of carbon and nitrogen fluxes in forest ecosystems from cell to stand level during the lifetime of trees. Establishing that metabolism and physical phenomena give rise to concentration, pressure and temperature differences that generate the material and energy fluxes between living organisms and their environment. The editors and authors utilize physiological, physical and anatomical background information to formulate theoretical ideas dealing with the effects of the environment and the state of enzymes, membrane pumps and pigments on metabolism. The emergent properties play an important role in the transitions from detailed to more aggregate levels in the ecosystem. Conservation of mass and energy allow the construction of dynamic models of carbon and nitrogen fluxes and pools at various levels in the hierarchy of forest ecosystems.

Physiology in extreme conditions can reveal important reactions of the human body, which help our assessment of limits emerging under healthy conditions and critical signals of transition toward disease. While many mechanisms could simply be associated with adaptations, others refer to unexpected reactions in response to internal stimuli and/or external abrupt changes.
