Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed--a toxic plant named for the sticky white substance emitted when its leaves are damaged--and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed--the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers.Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

    Zimmer brings the same story-telling skills he displayed in The Tangled Bank, his 2009 non-majors textbook that the Quarterly Review of Biology called "spectacularly successful." Emlen, an award-winning evolutionary biologist at the University of Montana, has infused Evolution: Making Sense of Life with the technical rigor and conceptual depth that today's biology majors require. Students will learn the fundamental concepts of evolutionary theory, such as natural selection, genetic drift, phylogeny, and coevolution. Evolution: Making Sense of Life also drives home the relevance of evolution for disciplines ranging from conservation biology to medicine. With riveting stories about evolutionary biologists at work everywhere from the Arctic to tropical rain forests to hospital wards, the book is a reading adventure designed to grab the imagination of the students, showing them exactly why it is that evolution makes such brilliant sense of life.

    Authors Peter Tompkins and Christopher Bird suggest that the most far-reaching revolution of the 20th century — one that could save or destroy the planet — may come from the bottom of your garden."Almost incredible ... bristles with plenty of hard facts and astounding scientific and practical lore." —S. K. Oberbeck, Newsweek“This fascinating book roams ... over that marvelous no man's land of mystical glimmerings into the nature of science and life itself." —Henry Mitchell, Washington Post Book World“If I can't ‘get inside a plant’ or ‘feel emanations’ from a plant and don't know anyone else who can. that doesn't detract one whit from the possibility that some people can and do. . . .According to The Secret Life of Plants, plants and men do inter-relate, with plants exhibiting empathetic and spiritual relationships and showing reactions interpreted as demonstrating physical-force connections with men. As my students say, ‘hey, wow!’"—Richard M. Klein, Professor of Botany, University of Vermont (in Smithsonian)

    And with only one exception-watering-container gardening is a whole lot easier. Beginning with the down-to-earth basics of soil, sun and water, fertilizer, seeds and propagation, The Bountiful Container is an extraordinarily complete, plant-by-plant guide.Written by two seasoned container gardeners and writers, The Bountiful Container covers Vegetables-not just tomatoes (17 varieties) and peppers (19 varieties), butharicots verts, fava beans, Thumbelina carrots, Chioggia beets, and sugarsnap peas. Herbs, from basil to thyme, and including bay leaves, fennel, and saffron crocus. Edible Flowers, such as begonias, calendula, pansies, violets, and roses. And perhaps most surprising, Fruits, including apples, peaches, Meyer lemons, blueberries, currants, and figs-yes, even in the colder parts of the country. (Another benefit of container gardening: You can bring the less hardy perennials in over the winter.) There are theme gardens (an Italian cook's garden, a Four Seasons garden), lists of sources, and dozens of sidebars on everything from how to be a human honeybee to seeds that are All America Selections.
