Book Description
With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.

Book Description
Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of “primary” sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Book Description
The Earth has reached a tipping point. Runaway climate change, the sixth great extinction of planetary life, the acidification of the oceans—all point toward an era of unprecedented turbulence in humanity’s relationship within the web of life. But just what is that relationship, and how do we make sense of this extraordinary transition? Anthropocene or Capitalocene? offers answers to these questions from a dynamic group of leading critical scholars. They challenge the theory and history offered by the most significant environmental concept of our times: the Anthropocene. But are we living in the Anthropocene, literally the “Age of Man”? Is a different response more compelling, and better suited to the strange—and often terrifying—times in which we live? The contributors to this book diagnose the problems of Anthropocene thinking and propose an alternative: the global crises of the twenty-first century are rooted in the Capitalocene, the Age of Capital. Anthropocene or Capitalocene? offers a series of provocative essays on nature and power, humanity, and capitalism. Including both well-established voices and younger scholars, the book challenges the conventional practice of dividing historical change and contemporary reality into “Nature” and “Society,” demonstrating the possibilities offered by a more nuanced and connective view of human environment-making, joined at every step with and within the biosphere. In distinct registers, the authors frame their discussions within a politics of hope that signal the possibilities for transcending capitalism, broadly understood as a “world-ecology” that joins nature, capital, and power as a historically evolving whole. Contributors include Jason W. Moore, Eileen Crist, Donna J. Haraway, Justin McBrien, Elmar Altvater, Daniel Hartley, and Christian Parenti.
