Design and Analysis of Ecological Experiments
Ecological research and the way that ecologists use statistics continues to change rapidly. This second edition of the best-selling Design and Analysis of Ecological Experiments leads these trends with an update of this now-standard reference book, with a discussion of the latest developments in experimental ecology and statistical practice. The goal of this volume is to encourage the correct use of some of the more well known statistical techniques and to make some of the less well known but potentially very useful techniques available. Chapters from the first edition have been substantially revised and new chapters have been added. Readers are introduced to statistical techniques that may ...
Design and Analysis of Ecological Experiments
The goal of this book is to make some underutilized but potentially very useful methods in experimental design and analysis available to ecologists, and to encourage better use of standard statistical techniques. Ecology has become more and more an experimental science in both basic and applied work,but experiments in the field and in the laboratory often present formidable statistical difficulties. Organized around providing solutions to ecological problems, this book offers ways to improve the statistical aspects of conducting manipulative ecological experiments, from setting them up to interpreting and reporting the results. An abundance of tools, including advanced approaches, are made available to ecologists in step-by-step examples, with computer code provided for common statistical packages. This is an essential how-to guide for the working ecologist and for graduate students preparing for research and teaching careers in the field of ecology.
Dangerous Liaisons?
With the advent of genetic engineering, "designer" crops might interbreed with natural populations. Could such romances lead to the evolution of "superweeds", as some have suggested? But haven't crops had sex with wild plants in the past? Has such gene swapping occurred without consequences? And if consequences have indeed occurred, what lessons can be gleaned for engineered crops? In Dangerous Liaisons? Norman Ellstrand examines these and other questions. He begins with basic information about the natural hybridization process. He then describes what we now know about hybridization between the world's most important crops—such as wheat, rice, maize, and soybeans—and their wild relatives...
Phenotypic Plasticity
"The author begins by defining phenotypic plasticity and detailing its history, including important experiments and methods of statistical and graphical analysis. He then provides extended examples and discussion of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media.".

The Biology of Aquatic and Wetland Plants
Aquatic plants play a critically important role in maintaining ecosystem health. They are natural biological filters in freshwater and estuarine wetlands; they contribute to the reproductive success of many organisms, some of which are harvested for food; they assist in flood control; and they are prominent elements in the aesthetics and recreational use of freshwater and estuarine habitats. Despite this globally recognized importance, wetlands have faced and continue to face threats from the encroachment of human activities. The Biology of Aquatic and Wetland Plants is a thorough and up-to-date textbook devoted to these plants and their interactions with the environment. The focus is on bot...
Into the Bright Sunshine
"Hubert Humphrey, a fallen hero and a dying man, rose on rickety legs to approach the podium of the Philadelphia Convention Hall, his pulpit for the commencement address at the University of Pennsylvania. He clutched a sheaf of paper with his speech for the occasion, typed and double-spaced by an assistant from his extemporaneous dictation, and then marked up in pencil by Humphrey himself. A note on the first page, circled to draw particular attention, read simply, "30 years ago - Here." In this place, at that time, twenty-nine years earlier to be precise, he had made history. From the dais now, Humphrey beheld five thousand impending graduates, an ebony sea of gowns and mortarboards, broken by one iconoclast in a homemade crown, two in ribboned bonnets, and another whose headgear bore the masking-tape message HI MA PA. In the horseshoe curve of the arena's double balcony loomed eight thousand parents and siblings, children, and friends. Wearing shirtsleeves and cotton shifts amid the stale heat, they looked like pale confetti from where Humphrey stood, and their flash cameras flickered away, a constellation of pinpricks"--
