Book Description
Insect Photoperiodism reviews the many aspects of photoperiodism, particularly in insects, emphasizing the concepts that serve to place the subject in a meaningful relationship to the whole of modern biology. Photoperiodism is the study of the adaptive mechanisms by which living systems exploit this source of temporal information. Organized into 12 chapters, this book begins by discussing the relationships between an endogenous behavioral rhythm and the exogenous photoperiod. Aside from behavioral activities, it also shows that some observable developmental events tend to occur at species-typical times of the day and to be photoperiodically regulated. Notably, photoperiod may exert either or both of two regulatory effects on insect development: growth rate effects or polymorphism. Furthermore, the characteristics of some of the principal physiological rhythms that have been studied; role of photoperiod in the control of diapauses; and the circadian functions and theoretical nature of biological clock are explored in this book.

Book Description
This book examines the role of photoperiod (day length) in timing seasonal adaptations in plants, invertebrates, and vertebrates. The field is poised to make progress in the understanding of seasonal clocks at all levels of analysis, and Photoperiodism brings together experts working in disparate areas to stimulate conversation among investigators from all related disciplines.

Book Description
Interest in biological rhythms has been traced back more than 2,500]ears to Archilochus, the Greek poet, who in one of his fragments suggests ",,(i,,(VWO'KE o'olos pv{}J.tos txv{}pW7rOVS ~XH" (recognize what rhythm governs man) (Aschoff, 1974). Reference can also be made to the French student of medicine J. J. Virey who, in his thesis of 1814, used for the first time the expression "horloge vivante" (living clock) to describe daily rhythms and to D. C. W. Hufeland (1779) who called the 24-hour period the unit of our natural chronology. However, it was not until the 1930s that real progress was made in the analysis of biological rhythms; and Erwin Bunning was encouraged to publish the first, and still not outdated, monograph in the field in 1958. Two years later, in the middle of exciting discoveries, we took a breather at the Cold Spring Harbor Symposium on Biological Clocks. Its survey on rules considered valid at that time, and Pittendrigh's anticipating view on the temporal organization of living systems, made it a milestone on our way from a more formalistic description of biological rhythms to the understanding of their structural and physiological basis.

Book Description
The development of insects strongly depends on the photoperiodicity and temperature cycles of the surrounding environment. The double photoperiodic control in connection with the daylength and the interrelation between inductive and spontaneous processes are discussed as fundamental features for the physiology of photoperiodism. With his book the author proposes a new concept for a physiological basis of insect development. "The overall contribution of the book resides in its offering a series of concepts that can be discussed and tested. The ideas originating from Zaslavski's unique viewpoint should be of interest to those concerned with the evolution of life histories." (The Quarterly Review of Biology)

Book Description
Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause.

Book Description
Insect Clocks is mainly concerned with the phenomena in which ""environmental time"" has a practical implication for the life of insects for them to perform behavioral or physiological episodes at the ""right time"" and season. This text first discusses the concept of rhythms and clocks, along with the seasonal changes in the environment that affect a particular group of organisms. This book then explains circadian rhythms of insects. Photoperiodism and seasonal cycles of development; photoperiodic response, clock, and counter; and other types of insect clock are also tackled. This text concludes by explaining the anatomical location of photoreceptors and clocks. This publication will be invaluable to those interested in studying insects and their development affected by circles of influences.
