The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant Monarch butterflies are one of nature's most recognizable creatures, known for their bright colors and epic annual migration from the United States and Canada to Mexico. Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed—a toxic plant named for the sticky white substance emitted when its leaves are damaged—and how this inextricable and intimate relationship has been like an arms race over the millennia, a...
The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.
Inducible defenses--those often dramatic phenotypic shifts in prey activated by biological agents ranging from predators to pathogens--are widespread in the natural world. Yet research on the inducible defenses used by vertebrates, invertebrates, and plants in terrestrial, marine, and freshwater habitats has largely developed along independent lines. Tollrian and Harvell bring together leading researchers from all fields to review common themes and explore emerging ideas. Contributors examine organisms as different as unicellular algae and higher vertebrates, and consider defenses ranging from immune systems to protective changes in morphology, behavior, chemistry, and life history.
Combining breadth of coverage with detail, this logical and cohesive introduction to insect ecology couples concepts with a broad range of examples and practical applications. It explores cutting-edge topics in the field, drawing on and highlighting the links between theory and the latest empirical studies. The sections are structured around a series of key topics, including behavioral ecology; species interactions; population ecology; food webs, communities and ecosystems; and broad patterns in nature. Chapters progress logically from the small scale to the large; from individual species through to species interactions, populations and communities. Application sections at the end of each chapter outline the practicality of ecological concepts and show how ecological information and concepts can be useful in agriculture, horticulture and forestry. Each chapter ends with a summary, providing a brief recap, followed by a set of questions and discussion topics designed to encourage independent and creative thinking.
This book provides a thorough and up-to-date discussion of key issues in the supportive care of children with cancer. A variety of frequently encountered situations is covered, including infections, metabolic, cardiopulmonary and neurologic emergencies, tumor lysis syndrome, pain, emesis, mucositis, thrombotic disorders, nutritional problems, hyperleukocytosis and acute abdomen. Throughout the emphasis is firmly on evidenced-based guidance developed from the relevant literature. Information is presented in a manner that will enable readers quickly to locate advice when confronted by a supportive care problem in one of their patients. Helpful algorithms are provided and important “take home points” are highlighted in figures and tables. Supportive Care in Pediatric Oncology will be an invaluable source of assistance for a wide range of health professionals involved in pediatric cancer care.
Research is showing that plants are in constant and lively discourse--they communicate, signaling to remote organs within an individual, eavesdropping on neighboring individuals, and exchanging information with other organisms ranging from other plants to microbes to animals. Plants lack central nervous systems, and the mechanisms coordinating plant sensing, behavior, and communication are quite different from the systems that accomplish similar tasks in animals. But they are no less impressive from an evolutionary perspective. In "Plant Communication, "Karban puts an ear to the ground to reveal the world of plant communication and information sensing. He reveals their sensory capabilities, the learning capacity of plants, sensory signaling and communication, the different responses to pollinators and predators, and the mechanisms that undergird this impressive behavioral repertoire. The book shows that plants are hardly the inanimate organisms limited by their stationary existence."

This book investigates the induced responses of plants to herbivores and to diseases. Plant pathologists and entomologists will find that their disciplines have a lot in common when it comes to the interest in the transduction signals of plants that mediate induced responses. Induced Plant Defenses Against Pathogens and Herbivores will allow these two disciplines to converse and learn from their similarities and differences.
This new edition of Handbook of Pediatric Hematology and Oncology: Children's Hospital & Research Center Oakland features practical guidance on how to handle common inpatient and outpatient challenges seen in pediatric hematology and oncology. Designed as a rapid reference to the latest diagnostic and therapeutic protocols, the text is short and didactic and supplemented with practical algorithms and case studies throughout. Completely revised and updated, there are brand-new chapters on subjects including bone marrow transplantation, pain management and palliative care. Comprehensive, yet concise, the handbook presents essential guidelines on the diagnosis and management of the most common pediatric blood disorders and malignancies, in addition to chemotherapeutic drug information and transfusion protocols. Designed for medical students, residents, and fellows, this user-friendly portable reference is also the perfect companion on the ward for pediatric hematology and oncology nurses.
