The news that a flowering weed-mousear cress (Arabidopsis thaliana)-can sense the particular chewing noise of its most common caterpillar predator and adjust its chemical defenses in response led to headlines announcing the discovery of the first "hearing" plant. As plants lack central nervous systems (and, indeed, ears), the mechanisms behind this "hearing" are unquestionably very different from those of our own acoustic sense, but the misleading headlines point to an overlooked truth: plants do in fact perceive environmental cues and respond rapidly to them by changing their chemical, morphological, and behavioral traits. In Plant Sensing and Communication, Richard Karban provides the first comprehensive overview of what is known about how plants perceive their environments, communicate those perceptions, and learn. Facing many of the same challenges as animals, plants have developed many similar capabilities: they sense light, chemicals, mechanical stimulation, temperature, electricity, and sound. Moreover, prior experiences have lasting impacts on sensitivity and response to cues; plants, in essence, have memory.Nor are their senses limited to the processes of an individual plant: plants eavesdrop on the cues and behaviors of neighbors and - for example, through flowers and fruits - exchange information with other types of organisms. Far from inanimate organisms limited by their stationery existence, plants, this book makes unquestionably clear, are in constant and lively discourse.

Plants face a daunting array of creatures which eat them, bore into them and use virtually every plant part for food or shelter. However, plants are far from defenceless under attack. Although they cannot flee their attackers, they can produce defences, such as thorns, and can actively alter their chemistry and physiology in response to damage. For instance, young potato leaves being eaten by potato beetles respond by producing chemicals which inhibit beetle digestive enzymes. Research on these induced responses to herbivory has proceeded since the 1980s, and this comprehensive evaluation and synthesis of a rapidly-developing field provides state-of-the-discipline reviews, and highlights areas of research which might be productive. This overview should appeal to a wide variety of theoretical and applied researchers in ecology, evolutionary biology, plant biology, entomology and agriculture.

Most books and courses in ecology cover facts and concepts but don't explain how to actually do ecological research. How to Do Ecology provides nuts-and-bolts advice on organizing and conducting a successful research program. This one-of-a-kind book explains how to choose a research question and answer it through manipulative experiments and systematic observations. Because science is a social endeavor, the book provides strategies for working with other people, including professors and collaborators. It suggests effective ways to communicate your findings in the form of journal articles, oral presentations, posters, and grant and research proposals. The book also includes ideas to help you identify your goals, organize a season of fieldwork, and deal with negative results. In short, it makes explicit many of the unspoken assumptions behind doing good research in ecology and provides an invaluable resource for meaningful conversations between ecologists. This second edition of How to Do Ecology features new sections on conducting and analyzing observational surveys, job hunting, and becoming a more creative researcher, as well as updated sections on statistical analyses.

The essential insider’s guide for ecologists at all career stages—now completely updated and expandedMost books and courses in ecology focus on facts and concepts but do little to explain the process of research. How to Do Ecology provides nuts-and-bolts advice for organizing and conducting a successful research program. This fully updated and expanded edition explains how to ask and answer your own research questions using compelling study design and appropriate stats. Ecology doesn’t take place exclusively outdoors, so the book shares invaluable insights on topics such as identifying your goals, developing professional relationships, reading efficiently, and organizing a field season. Because the currency in ecology is publications, it also suggests effective ways to communicate your ideas through journal articles, oral presentations, posters, and grant proposals. This incisive handbook makes explicit many of the unstated rules that ecologists follow and serves as a practical resource for meaningful conversations about ecology.This new edition includes:Expanded emphasis on collecting and interpreting observational dataAn innovative new workshop for generating and evaluating creative research questionsHelpful tips on developing the skills most important to students, navigating your career path, writing efficiently, and more

This book was developed out of a symposium at the XVII International Congress of Entomology held in Hamburg, Germany, on August 21, 1984. This symposium was organized by Drs. William Bradshaw and Hugh Dingle, who subsequently asked us to edit the proceedings. The chapters represent, for the most part, papers that were read in Hamburg but have been expanded and updated. The goal of this volume is to provide a comprehensive view of current research on insect life cycles, including field and laboratory studies, broad comparisons among species or local populations, and intensive studies of single populations, as well as theoretical research. Of necessity, given the magnitude of research now being carried out on insects, some important research programs are not included, and therein lie the makings of future volumes. This volume is divided into three parts. The first part, Geographical Patterns in Insect Life Cycles, explores various applications of a comparative method that has been valuable in investigating the potential for variability in life history parameters and the relation of these parameters to important variables in the environment.
