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.

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.

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 Atlas of North American English provides the first overall view of the pronunciation and vowel systems of the dialects of the U.S. and Canada. The Atlas re-defines the regional dialects of American English on the basis of sound changes active in the 1990s and draws new boundaries reflecting those changes. It is based on a telephone survey of 762 local speakers, representing all the urbanized areas of North America. It has been developed by Bill Labov, one of the leading sociolinguists of the world, together with his colleagues Sharon Ash and Charles Boberg. The Atlas consists of a printed volume accompanied by an interactive CD-ROM. The print and multimedia content is also available online. Combined Edition: Book and Multimedia CD-ROM The book contains 23 chapters that re-define the geographic boundaries of North American dialects and trace the influence of gender, age, education, and city size on the progress of sound change; findings that show a dramatic and increasing divergence of English in North America; 139 four color maps that illustrate the regional distribution of phonological and phonetic variables across the North American continent; 120 four color vowel charts of individual speakers. The multimedia CD-ROM supplements the articles and maps by providing a data base with measurements of more than 100,000 vowels and mean values for 439 speakers; the Plotnik program for mapping each of the individual vowel systems; extended sound samples of all North American dialects; multimedia applications to enhance classroom presentations. Online Version: Book and CD-ROM content plus additional data The online version comprises the contents of the book and the multimedia CD-ROM along with additional data. It presents a wider selection of data, maps, and audio samples that will be recurrently updated; proffers simultaneous access to the information contained in the book and on the multimedia CD-ROM to all users in the university/library network; provides students with easy access to research material for classroom assignments.
