Book Description
5. 1. 1 Biological Rhythms and Clocks From an evolutionary perspective, the adaptation of an organism’s behavior to its environment has depended on one of life’s fundamental traits: biological rhythm generation. In virtually all light-sensitive organisms from cyanobacteria to humans, biological clocks adapt cyclic physiology to geophysical time with time-keeping properties in the circadian (24 h), ultradian (24 h) domains (Edmunds, 1988; Lloyd, 1998; Lloyd et al. , 2001; Lloyd and Murray, 2006; Lloyd, 2007; Pittendrigh, 1993; Sweeney and Hastings, 1960) By definition, all rhythms exhibit regular periodicities since they constitute a mechanism of timing. Timing exerted by oscillatory mechanisms are found throughout the biological world and their periods span a wide range from milliseconds, as in the action potential of n- rons and the myocytes, to the slow evolutionary changes that require thousands of generations. In this context, to understand the synchronization of a population of coupled oscillators is an important problem for the dynamics of physiology in living systems (Aon et al. , 2007a, b; Kuramoto, 1984; Strogatz, 2003; Winfree, 1967). Circadian rhythms, the most intensively studied, are devoted to measuring daily 24 h cycles. A variety of physiological processes in a wide range of eukaryotic organisms display circadian rhythmicity which is characterized by the following major properties (Anderson et al. , 1985; Edmunds, 1988): (i) stable, autonomous (self-sustaining) oscillations having a free-running period under constant envir- mental conditions of ca.

Book Description
Based on the award-winning PBS documentary series, Ring of Fire is this first-person account of the adventures of two English brothers as they explore the astonishingly rich cultures of the Indonesian archipelago. Their fascinating odyssey began in 1972 with a 2,500-mile voyage through the fabled Spice Islands, in search of the Greater Bird of Paradise. A decade of further exploration followed, during which the brothers lived among the Asmat cannibals of Papua and the healers of Bali, came face-to-face with the man-eating dragons of Komodo, and encountered the elusive dream wanderers of Borneo. Amid impenetrable rain forests, erupting volcanoes and startling natural beauty, the brothers have captured on film and in words the story of one of the most captivating and intriguing explorations ever made.

Book Description
Daily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24-hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus (SCN). This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physiological measures such as body temperature, heart rate and hormone release. Moreover, accumulating evidence suggests that dysfunction of the circadian rhythms due to genetic mutations or environmental factors (i.e., jet-lag or shift work) contribute to the development of many pathologies, including sleep disorders, mood and affective disorders such as major depression, bipolar disorder and schizophrenia, as well as the risk of metabolic and cardiovascular disorders.

Book Description
Elder examines how artists such as Brakhage, Artaud, Schneemann, Cohen and others have tried to recognize and to convey primordial forms of experiences. He argues that the attempt to convey these primordial modes of awareness demands a different conception of artistic meaning from any of those that currently dominate contemporary critical discussion. By reworking theories and speech in highly original ways, Elder formulates this new conception. His remarks on the gaps in contemporary critical practices will likely become the focus of much debate.

Book Description
John Lythgoe was one of the pioneers of the 'Ecology of Vision', a subject that he ably delineated in his classic and inspirational book published some 20 years ago [1]. At heart, the original book aimed generally to identify inter-relationships between vision, animal behaviour and the environment. John Lythgoe excelled at identifying the interesting 'questions' in the ecology of an animal that fitted the 'answers' presented by an analysis of the visual system. Over the last twenty years, however, since Lythgoe's landmark publication, much progress has been made and the field has broadened considerably. In particular, our understanding of the 'adaptive mechanisms' underlying the ecology of vision has reached considerable depths, extending to the molecular dimension, partly as a result of development and application of new techniques. This complements the advances made in parallel in clinically oriented vision research [2]. The current book endeavours to review the progress made in the ecology of vision field by bringing together many of the major researchers presently active in the expanded subject area. The contents deal with theoretical and physical considerations of light and photoreception, present examples of visual system structure and function, and delve into aspects of visual behaviour and communi cation. Throughout the book, we have tried to emphasise one of the major themes to emerge within the ecology of vision: the high degree of adaptability that visual mechanisms are capable of undergoing in response to diverse, and dynamic, environments and behaviours.

Book Description
This volume consists of invited papers from scientists of Chinese origin in the visual field from around the world. The papers cover all basic and applied aspects of the vertebrate and invertebrate visual systems, from photoreceptors to cortical neurons, presenting both review and new findings on the subjects. It is hoped that this book will serve as a guide to international research linkage between groups.
