Serpentine Geoecology of Western North America


Book Description

Geoecology is a fruitful interdisciplinary field, relating rocks to soils to plant and animal communities and studying the interactions between them. Modern geoecology especially concentrates on showing how geology and soils affect the structure, composition, and distribution of plant communities in a certain research area. This book applies the principles of geoecology to Western North America, and to a specific kind of rock, the fascinating serpentine belts that run along the continental margins of the West Coast from Alaska to Baja. The authors come from different disciplines: Alexander is a soil scientist, Coleman a geologist, Harrison a biological researcher, and Keeler-Wolfe a vegetation ecologist. It begins with an overview of the geology of this rock and this region, covering mineralogy, petrology, and stratigraphy of West Coast serpentine. It will continue with serpentine soils and their development and distribution, and serpentine effects on plants and vegetation and animals. The serpentine geoecology of the different regions of Western North America, concentrating on California, will conclude the study. So, this academic book should appeal to plant ecologists, soil scientists, researchers in geoecology, and students in advanced courses in soil science.




Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions


Book Description

The California Tortoiseshell, West Coast Lady, Red Admiral, and Golden Oak Hairstreak are just a few of the many butterfly species found in the floristically rich San Francisco Bay and Sacramento Valley regions. This guide, written for both beginning and experienced butterfly watchers by one of the nation’s best-known professional lepidopterists, provides thorough, up-to-date information on all of the butterfly species found in this diverse and accessible region. Written in lively prose, it discusses the natural history and conservation status for these butterflies and at the same time provides an integrated view of butterfly biology based on studies conducted in northern California and around the world. Compact enough for use in the field, the guide also includes tips on butterfly watching, photography, gardening, and more. * Discusses and identifies more than 130 species * Species accounts include information on identifying butterflies through behavior, markings, and host plants * Beautiful full-color plates illustrate top and bottom views of wings for easier identification * Includes a species checklist and a glossary




Genesis


Book Description

The seventy-five masterpieces presented here, drawn from public and private American collections, are among the most celebrated icons of African art, works that are superb artistic creations as well as expressions of a society's most profound conceptions about its beginnings. All are reproduced in color and are accompanied by entries that illuminate the distinctive cultural contexts that inspired their creation and informed their appreciation."--BOOK JACKET.




The Last Butterflies


Book Description

A remarkable look at the rarest butterflies, how global changes threaten their existence, and how we can bring them back from near-extinction Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender’s Blue? Or the St. Francis’ Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures—some numbering no more than what can be held in one hand. Drawing from his own first-hand experiences, Nick Haddad explores the challenges of tracking these vanishing butterflies, why they are disappearing, and why they are worth saving. He also provides startling insights into the effects of human activity and environmental change on the planet’s biodiversity. Weaving a vivid and personal narrative with ideas from ecology and conservation, Haddad illustrates the race against time to reverse the decline of six butterfly species. Many scientists mistakenly assume we fully understand butterflies’ natural histories. Yet, as with the Large Blue in England, we too often know too little and the conservation consequences are dire. Haddad argues that a hands-off approach is not effective and that in many instances, like for the Fender’s Blue and Bay Checkerspot, active and aggressive management is necessary. With deliberate conservation, rare butterflies can coexist with people, inhabit urban fringes, and, in the case of the St. Francis’ Satyr, even reside on bomb ranges and military land. Haddad shows that through the efforts to protect and restore butterflies, we might learn how to successfully confront conservation issues for all animals and plants. A moving account of extinction, recovery, and hope, The Last Butterflies demonstrates the great value of these beautiful insects to science, conservation, and people.




Solitary Wasps and Bees: Their Hidden World in the Siskiyou Mountains


Book Description

Mary Paetzel describes her intimate encounters with solitary wasps and bees, over a 30 year odyssey in the Siskiyou Mountains of SW Oregon. Mary describes the behaviors and lives of these tiny non-aggressive insects.







California Serpentines


Book Description

This is the first comprehensive treatment of an important segment of the flora of California: native plants that have varying degrees of fidelity to serpentine rock and soil that make up over 1100 square miles in the Coast Ranges and the Sierra Nevada. Many of California's unique endemic plants are found nowhere else but on serpentine; over 200 species, subspecies, and varieties of native plants are restricted to some degree to serpentine. The author describes the geology, soils, and mineral nutrition of serpentines (low in normal essential nutrients, high in magnesium, iron, and toxic heavy metals, nickel, and chromium), the vegetation and flora that tolerate this inhospitable habitat, the fauna on serpentines, and management/conservation problems associated with serpentines. This is an essential guide to an important aspect of the flora of California.




California Grasslands


Book Description

"This highly synthetic and scholarly work brings together new and important scientific contributions by leading experts on a rich diversity of topics concerning the history, ecology, and conservation of California's endangered grasslands. The editors and authors have succeeded admirably in drawing from a great wealth of recent research to produce a widely accessible and compelling, state-of-the-art treatment of this fascinating subject. Anyone interested in Californian biodiversity or grassland ecosystems in general will find this book to be an invaluable resource and a major inspiration for further research, management, and restoration efforts."—Bruce G. Baldwin, W. L. Jepson Professor and Curator, UC Berkeley "Grasses and grasslands are among the most important elements of the California landscape. This is their book, embodying the kind of integrated view needed for all ecological communities in California. Approaches ranging across an incredibly broad spectrum -- paleontology and human history; basic science and practical management techniques; systematics, community ecology, physiology, and genetics; physical factors such as water, soil nutrients, atmospherics, and fire; biological factors such as competition, symbiosis, and grazing -- are nicely tied together due to careful editorial work. This is an indispensable reference for everyone interested in the California environment."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, UC Berkeley "The structure and function of California grasslands have intrigued ecologists for decades. The editors of this volume have assembled a comprehensive set of reviews by a group of outstanding authors on the natural history, structure, management, and restoration of this economically and ecologically important ecosystem."—Scott L. Collins, Professor of Biology, University of New Mexico
