Nematodes as Biological Models, Volume 2: Aging and Other Model Systems contains discussions on free-living nematodes as biological models for pharmacologic and toxicant testing, and for studies on gerontology and nutrition. The book presents specific chapters that cover topics on nematodes as models to study aging; nematodes as nutritional models; physiology and morphology of nematodes; and models and mechanisms on longevity and survival in nematodes. Geneticists, cell and developmental biologists, neurologists, endocrinologists, toxicologists, nutritionists, and gerontologists will find the book invaluable.
