Biological Rhythms and Photoperiodism in Plants brings together disparate subject areas into one accessible text of interest to all plant biologists. In this comprehensive volume, leading international researchers review our current understanding of circadian rhythms from a broad perspective. The book begins with a description of well known rhythmic processes such as gene expression, stomatal guard cell opening, and the movement of petals and leaves. Photoperiodic responses such as dormancy, bulbing, tuberization and flowering are then discussed in terms of their rhythmic behaviour. The latest data from current studies with mutant and transgenic plants is also included.

Rhythmic Phenomena in Plants, Second Edition focuses on the study of biological clocks in all kinds of plants, from unicellular algae to flowering trees. This book discusses the patterns of plant movement, parameters of rhythms and how to calculate them, and rhythms that match and do not match environmental periodicities. The mechanism of circadian timing, circadian rhythms in angiosperms, comparison between dinoflagellates and other rhythmic organisms, and semilunar and lunar rhythms are also elaborated. This publication likewise covers the measurement of day length in photoperiodism, circannian rhythms in plants, oscillations with short periods in leaves and roots, and streaming in a slime mold. This edition is valuable to biologists intending to contribute to the study of biological timing.

Life evolves in a cyclic environment, and to be successful, organisms must adapt not only to their spatial habitat, but also to their temporal habitat. How do plants and animals determine the time of year so they can anticipate seasonal changes in their habitats? In most cases, day length, or photoperiod, acts as the principal external cue for determining seasonal activity. For organisms not living at the bottom of the ocean or deep in a cave, day follows night, and the length of the day changes predictably throughout the year. These changes in photoperiod provide the most accurate signal for predicting upcoming seasonal conditions. Measuring day length allows plants and animals to anticipate and adapt to seasonal changes in their environments in order to optimally time key developmental events including seasonal growth and flowering of plants, annual bouts of reproduction, dormancy and migration in insects, and the collapse and regrowth of the reproductive system that drives breeding seasons in mammals and birds. Although research on photoperiodic time measurement originally integrated work on plants and animals, recent work has focused more narrowly and separately on plants, invertebrates, or vertebrates. As the fields have become more specialized there has been less interaction across the broader field of photoperiodism. As a result, researchers in each area often needlessly repeat both theoretical and experimental work. For example, understanding that there are genetically distinct morphs among species that, depending on latitude, respond to different critical photoperiods was discovered separately in plants, invertebrates, and vertebrates over the course of 20 years. However, over the past decade, intense work on daily and seasonal rhythms in fruit flies, mustard plants, and hamsters and mice, has led to remarkable progress in understanding the phenomenology, as well as the molecular and genetic mechanisms underlying circadian rhythms and clocks. This book was developed to further this type of cooperation among scientists from all related disciplines. It brings together leading researchers working on photoperiodic timing of seasonal adaptations in plants, invertebrates, and vertebrates. Each of its three sections begins with an introduction by the section editor, and at the end of the book, the section editors present a synthesis of common themes in photoperiodism, as well as discuss similarities and differences in approaches to the study of photoperiodism, and future directions for research on photoperiodic time measurement.

Introducing Biological Rhythms is a primer that serves to introduce individuals to the area of biological rhythms. It describes the major characteristics and discusses the implications and applications of these rhythms, while citing scientific results and references. Also, the primer includes essays that provide in-depth historic and other background information for those interested in more specific topics or concepts. It covers a basic cross-section of the field of chronobiology clearly enough so that it can be understood by a novice, or an undergraduate student, but that it would also be sufficiently technical and detailed for the scientist.

(Chapters 11 to 14) summarise important features of the biological clock at the level of whole animal covering all vertebrate classes (fish to mammal). Chapters 15 and 16 are on long term (seasonal) rhythms in plants and higher vertebrates. Short term rhythms (ultradian rhythms), the significance of having a clock system in animals living in extreme (arctic) environments, and the diversity of circadian responses to melatonin, the key endocrine element involved in regulation of biological rhythms, have been discussed in Chapters 17 to 19. Finally, a chapter on sensitivity to light of the photoperiodic clock is added which, using vertebrate examples, illustrates the importance of wavelength and intensity of light on circadian and non-circadian functions. A well-known expert writes each chapter. When presenting information, the text provides consistent thematic coverage and feeling for the methods of investigation. Reference citation within the body of the text adequately reflects the literature as subject is developed. A chapter begins with an abstract that enables a reader to know at the first glance the important points covered in that chapter. The chapter concludes with a full citation of references included in the text, which could be useful for further reading. The book ends with a comprehensive subject index that may be useful for quick searches.

An Introduction to Biological Rhythms provides an introduction to the subject of biological rhythms. The opening chapters present an overview of biological rhythms, their properties, and clock control, followed by a survey of rhythms in plants and animals. The subsequent chapters cover tidal rhythms and human rhythms; sun-compass, star-compass, and moon compass orientation of animals; the clock control of plant and animal photoperiodism; evidence for external timing of biological clocks; and models and mechanisms for endogenous timekeeping. The book also includes biographical sketches of Dr. Frank A. Brown, Jr., Morrison Professor of Biology at Northwestern University; and Dr. Leland N. Edmunds, Jr., Professor and Head of the Division of Biological Sciences at the Stony Brook campus of the State University of New York. This book is meant for the inquiring student seeking an introduction to the subject and for busy biologists in other fields who want to get a ""feel"" for the subject. It can also serve as a basic textbook for the existing biorhythms courses and act as a seed for the inauguration of new courses.

Pigment of the Imagination chronicles the story of phytochrome, the bright-blue photoreversible pigment through which plants constantly monitor the quality and presence of light. The book begins with work that led to the discovery of phytochrome and ends with the latest findings in gene regulation and expression. The phytochrome story provides a paradigm for the process of scientific discovery. This book should thus be of interest to scientists who work on phytochrome and related subjects in plant science, as well as to all scientists and science historians interested in how a scientific research field begins, develops, and matures. Documents the science and history of phytochrome research over an 80 year span Combines information from scientific literature, archival documents, and in-person inteviews Describes in scholarly and readable style an elegant example of biological discovery Accessible to researchers and students in all areas of science and history of science

This monograph provides a balanced treatment of some important aspects of biological rhythmicity. The topics focus on: the evolution and basic features of the circadianrhythms; genetics and molecular biology of the clock, and the circadian system at cellular level; ultradian and circadian rhythms at the level of whole animal (from fish to mammal); the perception of natural zeitgebers, photoentrainment and synchronization of long term physiological events to day lengths in organisms, with special reference to plants and higher vertebrates; and the peripheral clock system, the importance of biological rhythms in animals living in extreme arctic environment and the diversity of circadian responses to melatonin.
