Critical issues in plant health: 50 years of research in African agriculture
Focuses on plant health issues in sub-Saharan Africa which are key to improving yields Reviews ways of improving the health of key African crops such as cassava, maize and grain legumes Brings together leading experts on plant health in sub-Saharan Africa
Insect Herbivore-Host Dynamics
Literature on the population dynamics of insect herbivores tends to favour a top-down regulation of abundance, owing much to the action of natural enemies. Originally published in 2005, this volume challenges this paradigm and argues that tree-dwelling species of aphids, through competition for resources, regulate their own abundance. The biology of tree-dwelling aphids is examined, particularly their adaptation to the seasonal development of their host plants. When host-plant quality is favourable, aphids, by telescoping generations, can achieve prodigious rates of increase which their natural enemies are unable to match. Using analyses of long-term population censuses and results of experiments, this book introduces students and research workers to insect herbivore-host dynamics using the interaction between aphids and trees as a model.
Emerging Technologies to Benefit Farmers in Sub-Saharan Africa and South Asia
Increased agricultural productivity is a major stepping stone on the path out of poverty in sub-Saharan Africa and South Asia, but farmers there face tremendous challenges improving production. Poor soil, inefficient water use, and a lack of access to plant breeding resources, nutritious animal feed, high quality seed, and fuel and electricity-combined with some of the most extreme environmental conditions on Earth-have made yields in crop and animal production far lower in these regions than world averages. Emerging Technologies to Benefit Farmers in Sub-Saharan Africa and South Asia identifies sixty emerging technologies with the potential to significantly improve agricultural productivity in sub-Saharan Africa and South Asia. Eighteen technologies are recommended for immediate development or further exploration. Scientists from all backgrounds have an opportunity to become involved in bringing these and other technologies to fruition. The opportunities suggested in this book offer new approaches that can synergize with each other and with many other activities to transform agriculture in sub-Saharan Africa and South Asia.
Trait-Mediated Indirect Interactions
This book reviews state-of-the-art research into trait-based effects and their importance in community and ecosystem ecology.
Biological Control of Tropical Weeds Using Arthropods
This book discusses the biological control of weeds using arthropods, providing ecological management models for use across the tropical world.
Education as the Practice of Eco-Social-Cultural Change
The current ecological crisis is the consequence of entrenched attitudes, discourses and behaviours in human societies worldwide, fostered and reinforced through modern educational traditions, processes and institutions. This book envisions a radical transformation of education to focus on the mutual flourishing of human societies with the rest of life on Earth. In part, the authors suggest approaching this as a problem of systemic design, incorporating principles that challenge and undermine key premises of the Capitalocene—the socio-economic-political landscape sustaining the current educational regime. Tracing the implications of this transition, they review core assumptions of modern Western culture that need to shift, and identify a wide range of relevant capacities and practices grouped under four complementary educator “stances” for eco-social-cultural change.
Aphid Ecology An optimization approach
This second edition covers the evolution of aphids and their development in relation to specific plants, thoroughly revised and expanded since the first highly successful edition. Increasing knowledge of aphids has revealed that they are ideal organisms to use when studying many topical ecological issues.
Genetics, Evolution, and Biological Control
Annotation. This book has been developed from the keynote addresses delivered at the third IOBC International Symposium (co-organized with CILBA) that was held in Montpellier in October 2002, to address recent developments in genetics and evolutionary biology as applied to biological control. Chapters are organized around the following themes: Genetic structure of pest and natural enemy populations Molecular diagnostic tools in biological control Tracing the origin of pests and natural enemies Predicting evolutionary change in pests and natural enemies Compatibility of transgenic crops and natural enemies Genetic manipulation of natural enemies. The authors identify new issues for each of the major approaches in applied biological control. These include the (1) use of molecular genetics to trace the origin of target pests in classical biological control, (2) potential of mass-reared, transgenic agents in augmentative biological control, and (3) compatibility of transgenic crops and natural enemies in conservational biological control.
