While the subject of environmental stress in animals is broad, the available information is fragmentary and lacks an up-to-date overview and analysis. Environmental Stress and Cellular Response in Arthropods fills these knowledge gaps. Written by three experts from the same institution, the chapters have a consistency not often found in multi-authored or contributed books. The authors describe environmental stress in arthropods, specifically Drosophila and analyze the process in all its aspects, from biochemical mechanisms to effects on the whole organism. Incorporating new information that has become available in recent years, the authors explore hypotheses about the integrated response these systems often have. They explore topics ranging from disturbance of homeostasis, changes in metabolic processes, damage of cellular structures to acquired tolerance, effects on aging processes, and survival and cell death. By analyzing all these aspects in detail at the molecular, biochemical, and physiological level of the cell, the authors give you a thorough look at the relationship between an organism and its environment at the cellular level.
