Book excerpt: Dormancy and Developmental Arrest: Experimental Analysis in Plants and Animals discusses the experimentation on states of suspended animation of living organisms. The book presents the range and complexity of interconnected processes involving structural, physiological, and molecular alterations in the organism. The text describes the physiological responses of animals and plants to environmental signals. It discusses the activities of nucleic acid and protein synthesis prior to dormancy state. The text also describes plant embryo development and the regulation of body temperature in dormant states. The book will provide valuable insights for biologists, zoologists, botanists, students, and researchers in the field of biology.
