A scientific work discussing photoperiodism, the biological response of organisms to periodic changes in day and night length. The book examines physiological and ecological aspects in plants and insects, with emphasis on experimental findings and environmental adaptation.
This volume presents the proceedings of the Ciba Foundation Symposium on Photoperiodic Regulation of Insect and Molluscan Hormones (1983). It explores how environmental photoperiodic cues regulate hormonal systems in insects and molluscs. The chapters address circadian clocks, neuroendocrine mechanisms, juvenile and ecdysteroid hormones, diapause induction, reproductive timing, and comparative …
