Ecology of North America


Book Description

North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.




The Forgotten Peninsula


Book Description

The author deftly weaves the materials of natural and human history into a radiant, tightly woven fabric. . . . This classic is a book for all seasonsÑto be reread and savored over the years.ÑLatin America in Books "His superb writing style and the timelessness of his subject (the natural world and the interaction of human beings with it) make this every bit as enjoyable today as it was in the 1960's."ÑBooks of the Southwest "Well-written and fascinating."ÑJournal of Arid Environments




Physiological Ecology of North American Desert Plants


Book Description

Following a description of the physical and biological characterization of the four North American deserts together with the primary adaptations of plants to environmental stress, the authors go on to present case studies of key species. They provide an up-to-date and comprehensive review of the major patterns of adaptation in desert plants, with one chapter devoted to several important exotic plants that have invaded these deserts. The whole is rounded off with a synthesis of the resource requirements of desert plants and how they may respond to global climate change.

A New Island Biogeography of the Sea of Cort'es


Book Description

This updated and expanded A New Island Biogeography of the Sea of Cort'es, first published nearly 20 years ago, integrates new and broader studies encompassing more taxa and more complete island coverage. The present synthesis provides a basis for further research and exploration in upcoming years of the biologically fascinating Sea of Cort'es region. The Gulf region is increasingly being exploited, for its natural resources by way of marine fisheries, and for its stunning natural beauty by way of a burgeoning tourism industry. Further, the region's human population is increasing apace. It is appropriate, therefore, that this volume discusses these evolving circumstances, and the efforts of the Mexican government to regulate and manage them. The new Biogeography includes a section on the conservation issues in the Sea of Cort'es, past accomplishments and conservation needs as yet outstanding. This book should be of strong interest to conservation biologists, ecologists, and evolutionary biologists more generally.







An Archaeology of Abundance


Book Description

The islands of Alta and Baja California changed dramatically in the centuries after Spanish colonists arrived. Native populations were decimated by disease, and their lives were altered through forced assimilation and the cessation of traditional foraging practices. Overgrazing, overfishing, and the introduction of nonnative species depleted natural resources severely. Most scientists have assumed the islands were also relatively marginal for human habitation before European contact, but An Archaeology of Abundance reassesses this long-held belief, analyzing new lines of evidence suggesting that the California islands were rich in resources important to human populations. Contributors examine data from Paleocoastal to historic times that suggest the islands were optimal habitats that provided a variety of foods, fresh water, minerals, and fuels for the people living there. Botanical remains from these sites, together with the modern resurgence of plant communities after the removal of livestock, challenge theories that plant foods had to be imported for survival. Geoarchaeological surveys show that the islands had a variety of materials for making stone tools, and zooarchaeological data show that marine resources were abundant and that the translocation of plants and animals from the mainland further enhanced an already rich resource base. Studies of extensive exchange, underwater forests of edible seaweeds, and high island population densities also support the case for abundance on the islands. Concluding that the California islands were not marginal environments for early humans, the discoveries presented in this volume hold significant implications for reassessing the ancient history of islands around the world that have undergone similar ecological transformations.

Ecological Regions of North America


Book Description

This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.
