Book Description
The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant Monarch butterflies are one of nature's most recognizable creatures, known for their bright colors and epic annual migration from the United States and Canada to Mexico. 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.

Book Description
This new edition of a foundational text presents a contemporary review of cladistics, as applied to biological classification. It provides a comprehensive account of the past fifty years of discussion on the relationship between classification, phylogeny and evolution. It covers cladistics in the era of molecular data, detailing new advances and ideas that have emerged over the last twenty-five years. Written in an accessible style by internationally renowned authors in the field, readers are straightforwardly guided through fundamental principles and terminology. Simple worked examples and easy-to-understand diagrams also help readers navigate complex problems that have perplexed scientists for centuries. This practical guide is an essential addition for advanced undergraduates, postgraduates and researchers in taxonomy, systematics, comparative biology, evolutionary biology and molecular biology.

Book Description
In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults.

Book Description
A beautifully illustrated introduction to the lives of butterflies around the world There are more than fifteen thousand butterfly species in the world, fluttering through a wide variety of habitats. Bright and beautiful, butterflies also have fascinating life histories and play an important role in our planet’s ecosystems. The Lives of Butterflies showcases the extraordinary range of colors and patterns of the world’s butterflies while exploring their life histories, behavior, habitats and resources, populations, seasonality, defense and natural enemies, and threats and conservation. With remarkable photography, graphic illustration, and profiles of thirty-five selected species, this comprehensive and inviting book discusses dozens of key topics, including eggs, caterpillars, and chrysalids; flight, feeding, courtship, and mating; migration and hibernation; concealment, mimicry, and predators; habitat loss and fragmentation, climate change, and pesticides; and farming and gardening to support and attract butterflies. With its stunning illustrations and clear, up-to-date, and authoritative text, The Lives of Butterflies will appeal to a wide range of butterfly and nature lovers.

Book Description
Sharman Apt Russell again blends her lush voice and keen scientific eye in this marvelous book about butterflies. From Hindu mythology to Aztec sacrifices, butterflies have served as a metaphor for resurrection and transformation. Even during World War II, children in a Polish death camp scratched hundreds of butterflies onto the walls of their barracks. But as Russell points out in this rich and lyrical meditation, butterflies are above all objects of obsession. From the beastly horned caterpillar, whose blood helps it count time, to the peacock butterfly, with wings that hiss like a snake, Russell traces the butterflies through their life cycles, exploring the creatures' own obsessions with eating, mating, and migrating. In this way, she reveals the logic behind our endless fascination with butterflies as well as the driving passion of such legendary collectors as the tragic Eleanor Glanville, whose children declared her mad because of her compulsive butterfly collecting, and the brilliant Henry Walter Bates, whose collections from the Amazon in 1858 helped develop his theory of mimicry in nature. Russell also takes us inside some of the world's most prestigious natural history museums, where scientists painstakingly catalogue and categorize new species of Lepidoptera, hoping to shed light on insect genetics and evolution. A luminous journey through an exotic world of obsession and strange beauty, this is a book to be treasured by anyone who's ever watched a butterfly mid-flight and thought, as Russell has, "I've entered another dimension."

Book Description
Although no one had ever followed North American monarch butterflies on their annual southward journey to Mexico and California, in the 1990s there were well-accepted assumptions about the nature and form of the migration. But to Robert Michael Pyle, a naturalist with long experience in monarch conservation, the received wisdom about the butterflies’ long journey just didn’t make sense. In the autumn of 1996 he set out to uncover the facts, to pursue the tide of “cinnamon sailors” on their long, mysterious flight. Chasing Monarchs chronicles Pyle’s 9,000-mile journey to discover firsthand the secrets of the monarchs’ annual migration. Part road trip, part outdoor adventure, and part natural history study, Pyle’s book overturns old theories and provides insights both large and small regarding monarch butterflies, their biology, and their spectacular migratory travels. Since the book’s first publication, its controversial conclusions have been fully confirmed, and monarchs are better understood than ever before. The Afterword for this volume includes not only updated information on the myriad threats to monarch butterflies, but also various efforts under way to ensure the future of the world’s most amazing butterfly migration.

Book Description
Fritz Müller (1821-1897), though not as well known as his colleague Charles Darwin, belongs in the cohort of great nineteenth-century naturalists. Recovering Müller's legacy, David A. West describes the close intellectual kinship between Müller and Darwin and details a lively correspondence that spanned seventeen years. The two scientists, despite living on separate continents, often discussed new research topics and exchanged groundbreaking ideas that unequivocally moved the field of evolutionary biology forward. Müller was unique among naturalists testing Darwin's theory of natural selection because he investigated an enormous diversity of plants and animals, corresponded with prominent scientists, and published important articles in Germany, England, the United States, and Brazil. Darwin frequently praised Müller's powers of observation and interpretation, counting him among those scientists whose opinions he valued most. Despite the importance and scope of his work, however, Müller is known for relatively few of his discoveries. West remedies this oversight, chronicling the life and work of this remarkable and overlooked man of science.
