The new San Diego County Mammal Atlas serves as the definitive guide to the mammals of San Diego County, the biodiversity of which is one of the greatest in the United States. More than a decade in the making, the 432-page, full-color book covers the biology of all 91 terrestrial species and 31 inshore marine visitors known to have occurred in the county during recorded history (since 1769).
The Baja California Plant Field Guide is a manual to native and naturalized plants of the Baja California peninsula, Mexico. It is a useful guide for the entire Sonoran Desert and for Southern California, as over 50% of the species covered also occur in these regions. Over 715 different plants in 111 plant families are identified (most in both English and Spanish), with both scientific and common names and detailed descriptions. Many species are illustrated with color photographs. Descriptions entail plant habit and height; stem, leaf, flower, and fruit morphology; range; elevation; pollination biology; ethnobotanical uses; and discriminating comparisons with close relatives. This book is intended for everyone from the interested novice to the professional botanist.

An account of the distribution of 28 cetacean species that are known to have occurred in the waters off north-west Europe. Individual chapters cover particular species in detail, spanning identification, behaviour and social organisation, diet and habitat preferences, worldwide distribution and population status.
The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.
This vividly illustrated atlas is the essential wildlife reference, providing a spectacular visual survey of animals and their habitats across the globe.
The Salton Sea, California’s largest inland lake, supports a spectacular bird population that is among the most concentrated and most diverse in the world. Sadly, this crucial stopover along the Pacific Flyway for migratory and wintering shorebirds, landbirds, and waterfowl is dangerously close to collapse from several environmental threats. This book is the first thoroughly detailed book to describe the birds of Salton Sea, more than 450 species and subspecies in all. A major contribution to our knowledge about the birds of western North America, it will also be an important tool in the struggle to save this highly endangered area. Synthesizing data from many sources, including observations from their long-term work in the area, the authors’ species accounts discuss each bird’s abundance, seasonal status, movement patterns, biogeographic affinities, habitat associations, and more. This valuable reference also includes general information on the region’s fascinating history and biogeography, making it an unparalleled resource for the birding community, for wildlife managers, and for conservation biologists concerned with one of the most threatened ecosystems in western North America.
The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
