Book Description
Studies stimulated by the International Biological Program showed total insect faunal biomass and diversity to be greatest in the spring of the year, which matches increased plant growth and flowering at this time. Ground-inhabiting beetle studies indicated the family Tenebrionidae to be overwhelmingly dominant in biomass, but the family Staphylinidae to be richest in species numbers. Ant studies showed the chaparral community to be rich in ant species; seed gatherers were particularly important. Flower-visiting insects are more abundant and more species-rich in chaparral than in any other type of California vegetation. Bees especially are abundant and diversified and are responsible for most pollination. Postfire succession studies of insects indicate that the abundance of predators and flower visitors sharply increases following fire; parasitic and phytophagous insects (other than flower-visitors) increase more slowly. Insect herbivory appears to affect succession minimally.

Book Description
The characteristic look of California Chaparral—a soft bluish-green blanket of vegetation gently covering the hills—is known to millions who have seen it as the backdrop in movies and television productions. This complex ecological community of plants and animals is not just a feature of the hills around Hollywood, but is a quintessential part of the entire California landscape. It is a highly resilient community adapted to life with recurring fires and droughts. Written for a wide audience, this concise, engaging, and beautifully illustrated book describes an ancient and exquisitely balanced environment home to wondrous organisms: Fire Beetles that mate only on burning branches, lizards that shoot blood from their eyes when threatened, Kangaroo Rats that never drink water, and seeds that germinate only after a fire, even if that means waiting in the soil for a 100 years or more. Useful both as a field guide and an introductory overview of the ecology of chaparral, it also provides a better understanding of how we might live in harmony, safety, and appreciation of this unique ecological community. * Identifies chaparral’s common plants, animals, birds, reptiles, amphibians, and insects * Features 79 color illustrations, 56 black-and-white photographs, and 3 maps * Examines the role of humans and fire in chaparral, covering the placement and design of homes, landscaping, and public policy

Book Description
This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

Book Description
Ecologists are aware of the importance of natural dynamics in ecosystems. Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus. The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions.

Book Description
Human activities are causing species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Exploring mediterranean-type ecosystems - the Mediterranean Basin, California, Chile, Australia, and South Africa - this volume addresses the question whether biological diversity plays a significant role in the functioning of natural ecosystems, and to what extent that diversity can be reduced without causing system malfunction. Comparative studies in ecosystems that are similar in certain respects, but differ in others, offer considerable scope for gaining new insights into the links between biodiversity and ecosystem functioning.
