Book Description
Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. - Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) - Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production - Presents management systems that have been tested in the real-world by the authors of each chapter - Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world

Book Description
"Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
Oceanic islands represent a set of systems in which biological diversity varies as a consequence of remoteness or size, not environment; they are also generally simpler than continental ecosystems. Islands therefore provide an opportunity to determine the direct effects of biological diversity on ecosystem function. The volume addresses the components of biological diversity on islands and their patterns of variation; the modern threats to the maintenance of biological diversity on islands; the consequences of island biology and its modification by humanity regarding aspects of ecosystem function; the global implications of islands for conservation; and how islands can help one to understand the processes inducing changes throughout the world.

Book Description
Hawaiian Plant Life has been written with both the layperson and professional interested in Hawai‘i’s natural history and flora in mind. In addition to significant text describing landforms and vegetation, the evolution of Hawaiian flora, and the conservation of native species, the book includes almost 875 color photographs illustrating nearly two-thirds of native Hawaiian plant species as well as a concise description of each genus and species shown. The work can be used either as a stand-alone reference or as a companion to the two-volume Manual of the Flowering Plants of Hawai‘i. Learning more about threatened and endangered plants is essential to conserving them, and there is no more endangered flora in the world today than that of the Hawaiian Islands. Striking species complexes such as the silverswords and the remarkable lobeliads represent unique stories of adaptive radiation that make the Hawai‘i a living laboratory for evolution. Public appreciation for Hawaiian biodiversity requires outreach and education that will determine the future conservation of this rich heritage, and Hawaiian Plant Life has been designed to help fill that need.

Book Description
Three quarters of the U.S.’s bird and plant extinctions have occurred in Hawai‘i, and one third of the country’s threatened and endangered birds and plants reside within the state. Yet despite these alarming statistics, all is not lost: There are still 12,000 extant species unique to the archipelago and new species are discovered every year. In Restoring Paradise: Rethinking and Rebuilding Nature in Hawai‘i, Robert Cabin shows why current attempts to preserve Hawai‘i’s native fauna and flora require embracing the emerging paradigm of ecological restoration—the science and art of assisting the recovery of degraded species and ecosystems and creating more meaningful and sustainable relationships between people and nature. Cabin’s extensive experience as a research ecologist and applied practitioner enables him to provide a rare, behind-the-scenes look at successful and inspiring restoration programs. In Part 1 he recounts Hakalau Forest National Wildlife Refuge’s efforts to restore thousands of acres of degraded pasture on the island of Hawai‘i back to the native rain forests that once dominated the area and sheltered native birds now on the brink of extinction. Along the way, he presents an overview of Hawaiian natural and cultural history, biogeography, and evolutionary biology. Following chapters look at restoration work underway by the U.S. Park Service to reestablish native species within the vast Hawai‘i Volcanoes National Park; by a charismatic scientist and dedicated volunteers to restore the native forests of Auwahi on the southern slopes of Haleakalā; and by the Limahuli branch of Kauai’s National Tropical Botanical Garden to revive a thousand-year-old taro plantation. To investigate the compelling and often conflicting philosophies and strategies of those involved in restoration, Cabin opens Part 3 with interview excerpts from a cross-section of Hawai‘i’s environmental community. He concludes with a provocative and insightful discussion of the contentious, evolving relationship between humans and nature and the power and limitations of science within and beyond Hawai‘i.

Book Description
Stinging nettles harbour a characteristic community of insects that are widespread, abundant, and rewarding to study. This book describes the natural history of the insects in that community, and describes the way they coexist using different parts of a stinging nettle plant. It discusses the feeding habits of herbivores and predatory insects, and the parasites that feed on them, as well as the seasonal distribution of the life cycles of the different members of the community. For a nettle-dwelling insect species, a nettle patch is an island in a sea of unsuitable habitat, and this book discusses the relationship between the size and isolation of the nettle patch and the nature of its community. Keys are provided for identification, and many of the commoner species are illustrated in colour. Techniques are described for investigating insect fauna. A three page addendum draws attention to the changes in the nettle community that may be expected to result from global warming.

Book Description
The study of parasitoid communities has direct relevance to general ecological theory and to the applied practice of biological control. Yet, despite the existence of a large and active international research community involved in the study of parasitoids, until now no books devoted to the theme of parasitoid community ecology have been available. Here, with a healthy mix of general discussions and specific examples such as tortricids and weevils, the authors constructively review and evaluate our understanding of these often very complex systems. The book emphasizes basic science, linking the discussion to wider areas such as population dynamics, food webs, competition, and community structure. The more applied end of the subject is covered in a section exclusively devoted to biological control. This book, the first to deal entirely with ecological aspects of parasitoid biology, offers summaries of the state of the field by leading researchers and identifies critical areas in need of further investigation. Students, researchers, and teachers in the field of ecology, animal behavior, entomology, forestry, and agriculture will all want to have a copy of the book on their shelves.
