Introduction to Animal Physiology and Physiological Genetics, deals with topics on physiological measurement, comparisons, and analysis of the role of genotypes. This book emphasizes two aspects — the changes of physiological patterns in the course of development and the wide variation that can be found within a species. The text discusses the response mechanisms of living organisms from nerve impulses, chemical sense, muscle reaction, and includes some studies made on brain function. The effects of nutrition and energy such as the intake of food, water, oxygen, and the calculation of basic metabolic rates are explained. The book then discusses the role of the internal environment and that of the interstitial body fluid in the higher animals. The discussion covers blood circulation, cardiac cycle, and a special section on the function of the heartbeat in the spider Limulus showing that stimulation of the abdominal ganglia increases the heartbeats. The text also considers significant concepts of physiological genetics, and then explains asexual and sexual reproduction, the sex hormones of invertebrates, and the use of stimulants for animal production. The physiological differences between species are examined, but more particularly on the reservoir of genetic diversity, where differences abound between families and offspring. One research made in molecular biology concludes that genes are responsible for regulating the amino acid sequence of proteins. Molecular biologists, general biologists, zoologists, and microbiologists will find the articles in this collection invaluable.

Planarian Regeneration deals with regeneration problems including embryogenesis and morphogenesis. The book compares the principles involved in the regeneration processes with those in ontogenesis from the egg. The author also reviews the works of Thomas H. Morgan and Charles M. Child which became the basis for systematic scientific investigation of regeneration. The head regenerates vigorously, with a faster rate behind the eyes, then at various levels along the longitudinal axis of the planarian body. A time-graded regeneration includes inhibitory forces and some genetic codes that determine such rate. The time-graded field has been proven by transplantation experiments; the author addresses the morphological structure to which biochemical factors or processes determine the different rate of regeneration. He notes that the nervous system conforms to these processes as shown by studies of Lender and Klein (1961). The author suggests that the study of regeneration in planarians should involve time considerations quantitatively to explain some substance, if any, from the nervous system that activates the cytoplasm of neoblasts, and then the genome. This book will prove valuable for zoologists and researchers in genetics, biochemistry or molecular biology.
