In this volume, the study of legislatures has traditionally been a central preoccupation of political scientists. Legislatures provide good laboratories for testing theories and methodologies of significance in the discipline and, more broadly, for contributing to an understanding of how representative government works.

This is a one-of-a-kind introduction to the science of biology and its impact on the way we live. In Biology for a Changing World, two experienced educators and a science journalist explore the core ideas of biology through chapters written and illustrated in the style of a Scientific American article. Chapters don’t just feature compelling stories of real people—each chapter is a newsworthy story that serves as a context for covering the standard curriculum for the non-majors biology course. Updated throughout, the new edition offers new stories, enhanced plant and diversity coverage, and an expanded media program. Biology for a Changing World is supported by its own dedicated (and fully updated) version of LaunchPad, which fully integrates an interactive e-Book, all student media, a wide range of assessment and course management features.

Covering nearly three-quarters of our planet, the world's oceans are a vast and unique ecosystem from which all life on Earth originated. But each year the marine realm is more susceptible to harm by careless exploitation, and as demands for food, waste disposal, transport, and travel increase, the fate of the world's oceans hangs in the balance. This timely guide offers the nonscientist an opportunity to appreciate the importance of this expansive—and fragile—frontier. With selections chosen for their value in identifying the multiple uses of oceans, their resources, and the hurdles they face as the world's population continues to expand and consume their resources at a staggering rate, Oceans collects more than thirty thematically arranged articles from the past decade, including recent pieces written in the wake of the 2004 tsunami. The book features articles that investigate the origins of the world's oceans, the diversity of life in the water, the state of global fisheries, the dangers of natural disasters, and the perils oceans face, whether induced by nature or by humans. With breadth of topics as wide as the ocean is deep, this Scientific American reader will engage general readers interested in the evolution, ecology, and conservation of the oceanic ecosystem and can be used in courses on introductory oceanography, environmental science, and marine biology.

The Future of Energy: Earth, Wind and Fire by the Editors of Scientific American Since the Industrial Revolution our civilization has depended on fossil fuels to generate energy – first it was coal; then petroleum. But there are two problems: the first is that petroleum isn't an infinite resource; and the second is that burning coal and oil puts billions of tons of carbon dioxide into the atmosphere, trapping heat. Temperatures have risen by about 0.6 degrees Celsius over the last 100 years, which may not sound like much, but even that small increase is showing some large effects. For one, records have been set for the seasonal loss of arctic ice. If business as usual continues, we are looking at a world where sea levels will be high enough to submerge many coastal cities and extreme weather events like 2012's Hurricane Sandy are the new normal. In this eBook, The Future of Energy: Earth, Wind and Fire, we review the energy problem and analyze the options from the mundane to the far out, beginning in Section One with an overview of issues and solutions, including the comprehensive "A Path to Sustainable Energy by 2030" and "7 Radical Energy Solutions." As these authors show, a multitude of possibilities exist. Renewable energy is more than photovoltaic cells and wind turbines – though these are viable options – and subsequent sections look at various sources, including solar power, hydropower, geothermal power, nuclear power and yes, wind power. For example, Section 4's "Can Nuclear Power Compete" examines the possibilities for nuclear rebirth and Section 5's "Turning the Tide" and "Moving Parts" discuss how tides could power coastal cities. Meanwhile we need to power transportation, and Section 7 reviews the search for biofuels that do not negatively impact the environment. Of course, all technologies have drawbacks that must be addressed, and not every idea will succeed. That isn't the point. There's no choice but to change the way we power our lives. The question is how and when. The longer we wait, the more painful the transition will be.
