Book Description
THE EVOLUTIONARY STRATEGIES THAT SHAPE ECOSYSTEMS In 1837 a young Charles Darwin took his notebook, wrote “I think”, and then sketched a rudimentary, stick-like tree. Each branch of Darwin’s tree of life told a story of survival and adaptation – adaptation of animals and plants not just to the environment but also to life with other living things. However, more than 150 years since Darwin published his singular idea of natural selection, the science of ecology has yet to account for how contrasting evolutionary outcomes affect the ability of organisms to coexist in communities and to regulate ecosystem functioning. In this book Philip Grime and Simon Pierce explain how evidence from across the world is revealing that, beneath the wealth of apparently limitless and bewildering variation in detailed structure and functioning, the essential biology of all organisms is subject to the same set of basic interacting constraints on life-history and physiology. The inescapable resulting predicament during the evolution of every species is that, according to habitat, each must adopt a predictable compromise with regard to how they use the resources at their disposal in order to survive. The compromise involves the investment of resources in either the effort to acquire more resources, the tolerance of factors that reduce metabolic performance, or reproduction. This three-way trade-off is the irreducible core of the universal adaptive strategy theory which Grime and Pierce use to investigate how two environmental filters selecting, respectively, for convergence and divergence in organism function determine the identity of organisms in communities, and ultimately how different evolutionary strategies affect the functioning of ecosystems. This book refl ects an historic phase in which evolutionary processes are finally moving centre stage in the effort to unify ecological theory, and animal, plant and microbial ecology have begun to find a common theoretical framework.

Book Description
This volume presents an overview of recent advances, innovative applications, and future prospects of in vitro embryogenesis in higher plants. The book's chapters are divided into five parts: Part I contains reviews on general topics (microspore; zygotic and somatic embryogenesis; in vitro and in vivo asexual embryogenesis; advances on the genetic, physiological, and proteomic knowledge of somatic embryo formation; role of apoptosis and mitochondria in somatic embryogenesis; and innovation in the use of bioreactors). The remaining four parts discuss step-wise protocols on somatic embryogenesis in selected horticultural plants (Part II); forest trees (Part III); gametic embryogenesis (Part IV); and pivotal topics, such as the detection of epigenetics modifications during microspore embryogenesis, the in vitro embryogenesis and plant regenerations from isolated zygotes, the synthetics seed production, the induction and maturation of somatic embryos, and the cryostorage of embryogenic cultures (Part V). Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and thorough, In Vitro Embryogenesis in Higher Plants, is a useful source of information and ideas for plant tissue culturists, cell biologists, embryologists, horticulturists, and operators of commercial nurseries. This book will introduce the fascinating work in in vitro embryogenesis in higher plants to students and young scientists.

Book Description
Considered an essential conservation tool, plant reintroductions have been conducted for many of the world's rarest plant species. The expertise and knowledge gained through these efforts constitute an essential storehouse of information for conservationists faced with a rapidly changing global climate. This volume presents a comprehensive review of reintroduction projects and practices, the circumstances of their successes or failures, lessons learned, and the potential role for reintroductions in preserving species threatened by climate change. Contributors examine current plant reintroduction practices, from selecting appropriate source material and recipient sites to assessing population demography. The findings culminate in a set of Best Reintroduction Practice Guidelines, included in an appendix. These guidelines cover stages from planning and implementation to long-term monitoring, and offer not only recommended actions but also checklists of questions to consider that are applicable to projects around the world. Traditional reintroduction practice can inform managed relocation-the deliberate movement of species outside their native range-which may be the only hope for some species to persist in a natural environment. Included in the book are discussions of the history, fears, and controversy regarding managed relocation, along with protocols for evaluating invasive risk and proposals for conducting managed relocation of rare plants. Plant Reintroduction in a Changing Climate is a comprehensive and accessible reference for practitioners to use in planning and executing rare plant reintroductions.

Book Description
Molecular Biology of Plants presents the formal scientific presentations delivered on the symposium on plant molecular biology, held at the University of Minnesota in 1976. The topics in this book are organized around the central dogma of molecular biology. Section I describes the organization and replication of DNA in plant chromosomes, including chloroplast genomes; Section II discusses molecular aspects of transcription and translation, ribosomal RNA gene systems and hormonal control of protein synthesis. Section III examines plant viruses and bacterial agents, in particular the crown gall system, viroids, and the replication of plant RNA viruses. Each of these specific topics contributes to an integrated knowledge of plant molecular biology. The book will be of interest to geneticists, cell biologists, plant breeders, plant physiologists, plant pathologists, and biochemists.

Book Description
This book represents the first comprehensive study of how technocracy currently challenges representative democracy and asks how technocratic politics undermines democratic legitimacy. How strong is its challenge to democratic institutions? The book offers a solid theory and conceptualization of technocratic politics and the technocratic challenge is analyzed empirically at all levels of the national and supra-national institutions and actors, such as cabinets, parties, the EU, independent bodies, central banks and direct democratic campaigns in a comparative and policy perspective. It takes an in-depth analysis addressing elitism, meritocracy, de-politicization, efficiency, neutrality, reliance on science and distrust toward party politics and ideologies, and their impact when pitched against democratic responsiveness, accountability, citizens' input and pluralist competition. In the current crisis of democracy, this book assesses the effects of the technocratic critique against representative institutions, which are perceived to be unable to deal with complex and global problems. It analyzes demands for competent and responsible policy making in combination with the simultaneous populist resistance to experts. The book will be of key interest to scholars and students of comparative politics, political theory, policy analysis, multi-level governance as well as practitioners working in bureaucracies, media, think-tanks and policy making.
