The molecular basis of disease is the driving force in biomedical reserach. Gene detection, quantification, and localization are required to determine disease pathogenesis. In as much as DNA is the genetic potential in a particular organism, RNA and protein expression are the functional result of our genetic program. "Techniques in Localization of Gene Expression" describes in great detail the methods used to quantify and localize gene expression. Sensitive detection of gene expression is hindered by poor recovery or preservation of target sequences. "Techniques" emphasizes optimized methods to ensure full recovery and preservaiton of targets from specimen acquisition through detection of specific targets and final analysis. Situ Analyses of cells and tissues are also discussed. One of the weaknesses in biomedical research has been the use of in vitro model systems consisting of cell lines that may or may not mimic the in vivo conditions. These model systems are necessary to ask several questions on cell s and tissues with controllled variables int he absense of strategies to ask many questions at the same time. Multiparameter analysis can cirmcumvent the necessity fo in vitro model systems by allowing many quesitons to be answered on a cell or tissue at a single point in time. Using fluorescent dyes, on can answer many questions about a particular cell or tissue. One color, one question is an overriding theme of this book. The limitations of this approach are the number of colors in the spectrum and our ability to resolve them. Readers will find working protocols that have been developed and used routinely in the author's laboratory. Representative applications will be described using the various gene quantification and localization protocols to illustrate the utility of the techniques.

Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent."

Microbiology may be described as one of the younger sciences with its history, as a precise subject, only dating as far back as Pasteur in the mid 1800s and his revelation both of the role of microorganisms in nature and their importance to human welfare. Medical scientists rapidly took up the challenge, with their area of microbiology flourishing and expanding almost in complete isolation from the rest of biology. We now know, of course, that microorganisms have always played an important, if not essential role, in the biosphere with fermented foods and beverages, plant and animal diseases and nutrient cycling foremost in their sphere of activities. Within the last twenty years, microbiology has received two enormous boosts with the developments in microbial genetics and genetic engineering probably being the most influential, and the greater awareness of pollution and environmental sustainability following a close second. In 1990, your editor had the privilege and pleasure of being elected as President of The Association of Applied Biologists in the United King dom and, as the topic for his three-day Presidential Conference, chose 'The exploitation of microorganisms in applied biology'. This meeting stimu lated great interest in a wide range of subject areas, from weed control to nematology, from plant breeding to plant pathology, from mushrooms to mycorrhiza. The proceedings of this meeting were published in Aspects of Applied Biology, No. 24, 1990."
