Transgenic Organisms

This selected collection of contributions focuses on the modification of organisms through genetic manipulation. Scientists from various disciplines assess the quality of our knowledge on which risk assessment of gene technology methods is currently based. Molecular biology and ecology, but also aspects of evolutionary and population genetics, human genetics and genetically modified food are among the topics covered. The book analyzes the impetus behind, and progress in, research methods which have been introduced into gene-technology risk assessment procedures over the last three years, and, in so doing, reveals gaps in our understanding of evolutionary processes. The history of risk assessment and ethical implications with respect to the deliberate release of GMOs are considered. Finally, the transfer of knowledge from the laboratory to the public, and the role of the media in this process are discussed. This monograph will be of great interest to all those concerned with the risk assessment of genetechnology methods.

In 1992, a group of scientists including molecular biologists, microbiologists, population biolo­ gists, ecologists, human geneticists, moral philosophers and others met discussing the state of affairs regarding the deliberate or unintentional release of genetically modified organisms. The proceedings of this meeting were subsequently published by Birkhauser Verlag as Transgenic Organisms: Risk Assessment of Deliberate Release (K. Wohrmann and J. Tomiuk). Since then we have gained many new insights that are also worthy of discussion. And although other equally important scientific views on the release of genetically modified organisms exist, we have mainly concentrated on aspects of population biology and evolution. The results of a second meeting in 1995 are summarized here. We are grateful to colleagues and friends for their help in the translation, correction and review of the authors' contributions. We especially want to thank Jutta Bachmann, Donna Devine, Diana von Finck, Friedrich Laplace, Volker Loeschcke, Rolf Lorenz, Dave Parker and Trevor Petney. A grant (BMFT N' 0311035) from the Ministerium fUr Forschung und Technologie der Bundesrepublik Deutschland again made possible the continuation of this cooperative endeavour.
