Insect Clocks

About this book

Looks at the properties and functions of clock-like processes in insects. Covers circadian rythmicity as well as annual responses such as over-wintering diapause, seasonal morphs and cold hardiness.

Contents

Steel, X. Vafopoulou; the multioscillator circadian system; quantitative models for insect clocks, R.D. Lewis; circadian rhythms: photoreceptor and clock location; photoperiodism and seasonal cycles of development; the photoperiodic response; circadian rhythms in photoperiodism; the photoperiodic counter; photoperiodic time measurement: the clock-counter mechanism; photoperiodic photoreceptors and clock location; other types of insect clocks; clock complexity - the way forward?.
