he biological sciences are dominated by the idea that cells are the functionally autonomous, physically separated, discrete units of life. TThis concept was propounded in the 19th century by discoveries of the cellular structuring of both plants and animals. Moreover, the ap parent autonomy of unicellular eukaryotes, as well as the cellular basis of the mammalian brain (an organ whose anatomy for a long while defied attempts to validate the idea of the cellular nature of its neurons), seemed to provide the final conclusive evidence for the completeness of *cell theory', a theory which has persisted in an almost dogmatic form up to the present day. However, it is very obvious that there are n...
Volume One of the thoroughly revised and updated guide to the study of biodiversity in insects The second edition of Insect Biodiversity: Science and Society brings together in one comprehensive text contributions from leading scientific experts to assess the influence insects have on humankind and the earth’s fragile ecosystems. Revised and updated, this new edition includes information on the number of substantial changes to entomology and the study of biodiversity. It includes current research on insect groups, classification, regional diversity, and a wide range of concepts and developing methodologies. The authors examine why insect biodiversity matters and how the rapid evolution of ...
Aphids are well-known as pests of agriculture, horticulture and forestry, but they are also one of the most biologically interesting groups of plant-feeding insects, and thus have attracted the attention of biologists in many research fields such as ecology, biodiversity, physiology, behaviour and genetics. Following the successful format of previous books on the world's aphids by the same authors, these two volumes provide a comprehensive species-by-species account of the aphids on the world's herbaceous plants and shrubs. They can be used not only as an identification guide and information source for entomologists and taxonomists throughout the world, but also as a unique database for stud...
Thoroughly updated and revised throughout with brand new chapters on affective bodies, indeterminate bodies, assemblaged bodies and a new conclusion, and featuring essay and classroom questions for classroom use, The Body: Key Concepts, Second Edition, presents a concise and up-to-date introduction to, and analysis of, the complex and influential debates around the body in contemporary culture. Lisa Blackman outlines and illuminates those debates which have made the body central to current interdisciplinary thinking across the arts, humanities and sciences. Since body studies hit the mainstream, it has grown in new regions, including China, and moved in new directions to question what counts...
Life scientists are increasingly drawn to the study of comparative evolutionary biology. Insect Development and Evolution is the first synthesis of knowledge of insect development within an evolutionary framework and the first to survey the genetic, molecular, and whole organism literature. Bruce S. Heming provides a detailed introduction to the embryonic and postembryonic development of insects. Topics include:* reproductive systems,* male and female gametogenesis,* sperm transfer and use,* fertilization,* sex determination,* parthenogenesis,* embryogenesis,* postembryogenesis,* hormones,* and the role of ontogeny in insect evolution.Summaries for each of these topics cover structural event...
