In the race to feed the world’ s seven billion people, we are at a standstill. Over the past century, we have developed increasingly potent and sophisticated pesticides, yet in 2014, the average percentage of U.S. crops lost to agricultural pests was no less than in 1944. To use a metaphor the field of evolutionary biology borrowed from Alice in Wonderland, farmers must run ever faster to stay in the same place— i.e., produce the same yields. With Chasing the Red Queen, Andy Dyer offers the first book to apply the Red Queen Hypothesis to agriculture. He illustrates that when selection pressure increases, species evolve in response, creating a never-ending, perpetually-escalating competition between predator (us) and prey (bugs and weeds). The result is farmers are caught in a vicious cycle of chemical dependence, stuck using increasingly dangerous and expensive toxics to beat back progressively resistant pests. To break the cycle, we must learn the science behind it. Dyer examines one of the world’ s most pressing problems as a biological case study. He presents key concepts, from Darwin’ s principles of natural selection to genetic variation and adaptive phenotypes. Understanding the fundamentals of ecology and biology is the first step to “ playing the Red Queen,” and escaping her unwinnable race. The book’ s novel frame will help students, researchers, and policy-makers alike apply that knowledge to the critical task of achieving food security.

This collection of non-partisan reports written by award-winning CQ Researcher journalists focuses on provocative current policy issues. As an annual publication that comes together just months before it goes to press, the volume is all new and as up-to-date as possible. And because it’s CQ Researcher, the policy reports are expertly researched and written, showing all sides of an issue. Chapters follow a consistent organization—exploring three issue questions, then offering background, current context, and a look ahead—and feature a pro/con debate box. All issues include a chronology, bibliography, photos, charts, and figures. All selections are brand new and explore some of today’s most significant American public policy issues, including the marijuana industry, air pollution and climate change, racial conflict, housing discrimination, campus sexual assault, transgender rights, reforming veteran’s health care, and immigrant detention.

Tropical Forest Insect Pests, first published in 2007, promotes a better theoretical understanding of pest population dynamics, and causes of forest insect outbreaks in the tropics. Covering pests of both natural forests and plantations, it examines the diversity of tropical forest insects; their ecological functions; the concept of pests; and the incidence of pests in natural forests, plantations, and stored timber. General issues on which foresters and forest entomologists hold strong traditional views, such as the severity of pest incidence in plantations vs. natural forests, in plantations of exotics vs. indigenous tree species, and in monocultures vs. mixed plantations are discussed. The final section looks in detail at specific insect pests of the common plantation tree species across the tropics, with recommendations for their control. This is a comprehensive resource suitable for graduate students and researchers in forestry and tropical forest entomology, and for forest plantation managers in the tropics.

The incredible global diversity of ants, and their important ecological roles, mean that we cannot ignore the significance of ants in ecological systems. Ant Ecology takes the reader on a journey of discovery from the beginnings of ants many hundreds of thousands of years ago, through to the makings of present day distributions.

Fungi enjoy great popularity in pharmaceutical, agricultural, and biotechnological applications. Recent advances in the decipherment of whole fungal genomes promise an acceleration of these trends. This timely book links scientists from different parts of the world who are interested in the molecular identification of fungi combined with the exploration of the fungal biodiversity in different ecosystems. It provides a compendium for scientists who rely on a rapid and reliable detection of fungal specimens in environmental as well as clinical resources in order to ensure the benefit of industrial and clinical applications. Chapters focus on the opportunities and limits of the molecular marker-mediated identification of fungi. Various methods, procedures and strategies are outlined. Furthermore, the book offers an update of the current progress in the development of fungal molecular techniques, and draws attention to potential and associated problems, as well as integrating theory and practice.

Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.
