A key component in healthy ecosystems, lichens can be found in almost any natural habitat in the Pacific Northwest. This comprehensive guide to the region’s macrolichens is intended for use by beginners as well as specialists: weekend naturalists will be able to identify specimens and recognize the great diversity of lichens, while lichenologists and mycologists will gain greater knowledge of the distribution and abundance of various species.
This revised and expanded edition of Macrolichens of the Pacific Northwest includes 116 new species and 176 additional illustrations and incorporates an understanding of macrolichens that has advanced tremendously in the past decade.
Macrolichens of the Pacific Northwest includes keys to 113 genera and 586 species of Oregon and Washington macrolichens—all the macrolichens known or expected to occur in the two states. The keys also provide reasonable coverage for lichens of Idaho and Montana, inland to the Continental Divide. Color photographs and detailed descriptions are provided for 246 species, emphasizing lichens prevalent in forested ecosystems.
The illustrated glossary and introductory material cover the terminology needed to identify macrolichens and provide information on collection and handling. The biology, ecology, and air-quality sensitivity of lichens are discussed; regional air-quality sensitivities are provided for 184 species.
Macrolichens of the Pacific Northwest will prove invaluable to anyone seeking to identify lichens or to better understand these organisms and their vital role in the natural world.
The publishing of the Flora Graeca was a landmark event in 1830. Only 25 copies were published, due to the book’s size of 10 double folio volumes and its numerous illustrations, and it cost over £620, a colossal sum at the time. The Flora Graeca brought together beautiful renderings of the fruits of the travels of British scientist John Sibthorp, who made multiple trips to the eastern Mediterranean in the early nineteenth century to collect a rich array of exotic floral specimens. Now The Magnificent Flora Graeca chronicles Sibthorp’s immense undertaking, including brilliant selections from his groundbreaking volume.
The story of the expeditions of Sibthorp and his renowned illustrator Ferdinand Bauer is a tale replete with larger-than-life characters and adventures on land and sea. Harris profiles the lives of Sibthorp, Bauer, and other leading characters, and explores the Flora Graeca’s rich cultural and scientific legacy. Sibthorp’s pioneering adventures unearthed floral specimens previously unknown to science, as he collected the originals of such popular garden flowers as the Crocus flavus ssp. flavus, the parent of the Golden Yellow; and Cyprus’s Cyclamen persicum, the parent of the widely grown garden cyclamens species.
This new volume, drawn from photographs of Sibthorp’s remarkably well-preserved specimens and luminous reproductions of the original watercolors and engravings by Bauer, features more images from the Flora Graeca than have ever been published since its first printing.
A fascinating treasure of floral wonders, The Magnificent Flora Graeca is an essential addition to the bookshelf for the plant lover or anyone curious about the natural history behind their beloved garden retreats.
"This book is one-of-a-kind. It is the only book that I'm aware of that summarizes the biology, ecology, uses, and management of mesquite.... It is the most complete book in print on mesquite."
—C. Wayne Hanselka, Associate Department Head and Extension Program Leader for Rangeland Ecology and Management, Texas Agricultural Extension Service
A reliable source of food and shelter even in the severest droughts, the mesquite tree sustained American Indians in the Southwest for centuries. Today, mesquite is popular for barbecuing, woodworking, furniture making, flooring, sculpture, jewelry, and food products ranging from honey to jelly and syrup. Even ranchers, who once fought to eradicate mesquite, have come to value its multiple uses on well-managed rangeland.
In this book written especially for a general readership, one of the world's leading authorities on mesquite presents a wealth of information about its natural history and commercial, agricultural, and woodworking uses. Ken Rogers describes the life cycle, species, and wide distribution of the mesquite, which is native or naturalized not only in the Southwest and Mexico, but also in India, Africa, Australia, South America, and Hawaii. He discusses the many consumer and woodworker uses of mesquite at length-even giving instructions for laying a mesquite wood floor and making mesquite bean jelly. He also looks into the ways that people are using mesquite in nature, from rangeland management in the Southwest to desertification prevention in arid countries.
Now in its tenth decade of publication, Michigan Trees has been, since it was first introduced in 1913, the must-have reference book for anyone who wants to know about the trees of this unique North American region.
In this new and updated edition, several new species have been added to the lineup, as well as sections on tree ecology and fall color. Written and illustrated in a style that appeals at once to academic botanists and armchair arborphiles alike, Michigan Trees gives readers everything they need to know for identifying trees in the Great Lakes state. Included with each description are fascinating notes and asides (for example, this tidbit on the jack pine: "Parklike or savanna stands in north-central Michigan are prime habitat for the rare Kirtland's warbler that breeds nowhere else in the world."). Also includes a tree key and identification section illustrated with elegantly simple line drawings that reveal the tiny, signature details that make each tree unique.
Burton V. Barnes is Professor of Forestry at the University of Michigan. Formerly a research forester, he is best known for his research and publications in forest ecology and forest genetics.
Warren H. Wagner, Jr. was a world authority on ferns. He had been Professor Emeritus of Botany and Natural Resources at the University of Michigan before his death at the age of 80 in 2000.
The magnificent stands of old-growth trees that characterize the forests of western North America depend on periodic fires for their creation or survival. Deprived of that essential disturbance process eventually they die, leaving an overcrowded growth of smaller trees vulnerable to intense blazes and epidemics of insects and disease.
In Mimicking Nature's Fire, forest ecologists Stephen Arno and Carl Fiedler present practical solutions to the pervasive problem of deteriorating forest conditions in western North America. Advocating a new direction in forest management, they explore the promise of "restoration forestry" -- an ecologically based approach that seeks to establish forest structures in which fire can once again serve as a beneficial process rather than as a destructive aberration.
The book begins with an overview of fundamentals: why traditional forestry tried to exclude fire from forests, why that attempt failed, and why foresters and ecologists now recognize the need for management based on how natural ecosystems operate. Subsequent chapters consider: how fire's historic role provides a foundation for designing restoration strategies; why a hands-off approach will not return forests to their historical condition; how management goals influence the strategies used in restoration forestry.
The second part of the book presents case studies of restoration projects in the western United States and Canada, representing different forest types, different historic fire regimes, and contrasting management goals. For each project, the authors describe why and how the project is being conducted, profile forest conditions, and describe methods of treatment. They also report what has been accomplished, identify obstacles to restoration, and offer their candid but understanding evaluation. Mimicking Nature's Fire concludes by placing restoration forestry in the broad context of conserving forests worldwide and outlining factors critical for its success.
Short treatises attributed to a great mind.
Aristotle, great Greek philosopher, researcher, reasoner, and writer, born at Stagirus in 384 BC, was the son of a physician. He studied under Plato at Athens and taught there (367–347); subsequently he spent three years at the court of a former pupil in Asia Minor. After some time at Mitylene, in 343–342 he was appointed by King Philip of Macedon to be tutor of his teen-aged son Alexander. After Philip’s death in 336, Aristotle became head of his own school (of “Peripatetics”), the Lyceum at Athens. Because of anti-Macedonian feeling there after Alexander’s death in 323, he withdrew to Chalcis in Euboea, where he died in 322.
Nearly all the works Aristotle prepared for publication are lost; the priceless ones extant are lecture-materials, notes, and memoranda (some are spurious). They can be categorized as follows:
I Practical: Nicomachean Ethics; Great Ethics (Magna Moralia); Eudemian Ethics; Politics; Economics (on the good of the family); On Virtues and Vices.
II Logical: Categories; Analytics (Prior and Posterior); Interpretation; Refutations used by Sophists; Topica.
III Physical: Twenty-six works (some suspect) including astronomy, generation and destruction, the senses, memory, sleep, dreams, life, facts about animals, etc.
IV Metaphysics: on being as being.
V Art: Rhetoric and Poetics.
VI Other works including the Constitution of Athens; more works also of doubtful authorship.
VII Fragments of various works such as dialogues on philosophy and literature; and of treatises on rhetoric, politics, and metaphysics.
The Loeb Classical Library edition of Aristotle is in twenty-three volumes.
Molds, Mushrooms, and Mycotoxins was first published in 1975. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
As Professor Christensen has made evident in his earlier books, including The Molds and Man,fungi are significantly interesting in their life-styles and in the many ways in which they affect man. Here he continues his exploration of the lives of the fungi and their relation to man, focusing on the harmful or dangerous effects which certain molds, mushrooms, and other fungi can have on human beings.
The first several chapters deal with fungi that are toxic in one way or another: either the fungi themselves are toxic when consumed, as with poisonous mushrooms and ergot, or the fungi secrete toxic compounds that diffuse into the substance on which they grow, making that substance toxic when eaten. He discusses hallucinogenic as well as poisonous mushrooms and provides extensive information about mycotoxins in human and animal foods, which are recently discovered health hazards.
Other chapters deal with fungus spores, which are a major cause of respiratory allergies, and with fungi which are predators or parasites of insects and nematodes. A chapter is devoted to fungus infections of man and animals, which at times constitute a serious public health problem. Another chapter discusses the nature, cause, and prevention of wood decay in trees and buildings. In a final chapter the author discusses some aspects of organic evolution in general as a background for presenting theories and facts on the evolution of fungi. He summarizes some of the ways in which fungi enter into our lives and economy, and looks to the role of fungi in the future.
The illustrations, in both black and white and color, show some of the fungi and processes that are discussed.
Plants produce a considerable number of structures of one kind, like leaves, flowers, fruits, and seeds, and this reiteration is a quintessential feature of the body plan of higher plants. But since not all structures of the same kind produced by a plant are identical—for instance, different branches on a plant may be male or female, leaf sizes in the sun differ from those in the shade, and fruit sizes can vary depending on patterns of physiological allocation among branches—a single plant genotype generally produces a multiplicity of phenotypic versions of the same organ.
Multiplicity in Unity uses this subindividual variation to deepen our understanding of the ecological and evolutionary factors involved in plant-animal interactions. On one hand, phenotypic variation at the subindividual scale has diverse ecological implications for animals that eat plants. On the other hand, by choosing which plants to consume, these animals may constrain or modify plant ontogenetic patterns, developmental stability, and the extent to which feasible phenotypic variants are expressed by individuals.
An innovative study of the ecology, morphology, and evolution of modular organisms, Multiplicity in Unity addresses a topic central to our understanding of the diversity of life and the ways in which organisms have coevolved to cope with variable environments.
