Book Description
Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah K. Letourneau Focusing on three trophic levels, this study widens the current understanding of the ecological interactions between plants, herbivores, and their parasitoids and predators. Emphasized are the mediating effects of plant-derived allelochemicals on those interactions. The book also covers microorganisms as mediators of intertrophic and intratrophic interactions; theory and mechanisms: plant effects via allelochemicals on the third trophic level; and key roles of plant allelochemicals in survival strategies of herbivores. 1988 (0 471-83276-6) 362 pp. Plant-Animal Interactions Evolutionary Ecology in Tropical and Temperate Regions Edited by Peter W. Price, Thomas M. Lewinsohn, G. Wilson Fernandes and Woodruff W. Benson An outgrowth of an international symposium on Evolutionary Ecology of Tropical Herbivores held at UNICAMP, Brazil, this unique collaborative effort from leading scientists worldwide is the first comparative analysis of the existing ecological systems of temperate and tropical regions. In-depth and timely, the book's manifold analyses includes a discussion of tropical and temperate comparisons; mutualistic relationships between plants and animals; antagonistic relationships between plants and animals; plant-butterfly interactions; specificity in plant utilization; and community patterns in natural and agricultural systems. Amply illustrated with 150 detailed graphics, the book provides a fascinating visual tour of the flora and fauna described. 1991 (0 471-50937-X) 639 pp. Integrated Pest Management Systems and Cotton Production Edited by Raymond E. Frisbie, Kamal M. El-Zik and L. Ted Wilson This work sheds light on the link between the thriving U.S. cotton crop and integrated pest management. It offers a unique theoretical and conceptual framework for studying the cotton-IPM system. Other relevant issues such as the development and use of pest models, quantitative sampling principles in cotton IPM, economic injury levels and thresholds for cotton pests, and strategies and tactics for managing weeds, plant pathogens, nematodes, and insects are also described. Covering every facet of IPM technology, this is a significant contribution to the literature of pest management. 1989 (0 471-81782-1) 437 pp.

Book Description
The identification of inputs and outputs is the first and probably most important step in testing and analyzing complex systems. Following accepted natural laws such as the conservation of mass and the principle of electroneutrality, the input/output analysis of the system, be it steady or in connection with perturbations will reveal the status dynamic, will identify whether changes are reversible or irreversible and whether changing the input will cause a hysteresis response. Moreover, measurements ofinput and output fluxes can indicate the storage capacity ofa system, its resilience to buffer or amplify variations of the external input, and it can identify structural changes. Therefore, to a certain extent, the input/output analysis can facilitate predictions about the ecosystem stability. The measurement of fluxes and the determination of inputs and outputs of eco systems are, in many aspects, analogous to measurements done by engineers when testing an electronic apparatus. The first step is the measurement ofthe input/output properties of the instrument as a whole, or ofvarious circuit boards, and the compari· son ofthese with the expected variations of the original design. Varying input and out· put can give valuable information about the stability and the regulatory properties of the device. Nevertheless, only the circuit as an entity has specific properties which cannot be anticipated if the individual components are investigated regardless oftheir position. Also, the instrument as a whole will have different input/output properties than its subcircuits.

Book Description
This unique dictionary is an authoritative and up-to-date reference book on all aspects of the study of plants. While many of the over 5,000 entries in The Concise Oxford Dictionary of Botany have been taken from the highly acclaimed Oxford Dictionary of Natural History, a substantial number have been written especially for this volume. Completely comprehensive, this dictionary offers concise and accessible explanations of terms from biogeology, evolution, earth history, and all the earth sciences, as well as up-to-date entries on more current fields of interest such as ecology, genetics, plant physiology, biochemistry, and cytology. In addition, the book offers world-wide coverage of taxonomic groups and takes full account of recent taxonomical revisions. One-third of the entries are devoted to taxa, from bacteria and fungi to the main groups of flowering and non-flowering plants. Brief biographical sketches of important botanists are also included. With almost twice the number of entries as any similar dictionary, The Concise Oxford Dictionary of Botany is perfect for amateur botanists, and anyone interested in the world around us.
