Book excerpt: Excerpt from Life Zones and Crop Zones of the United States For ten years the Biological Survey (and its predecessor, the Divi Sion of Ornithology and Mammalogy) has had small parties in the field traversing the public domain for the purpose of studying the geographic distribution of our native land animals and plants and mapping the boundaries of the areas they inhabit. The present report is intended to explain the relations of this work to practical agriculture and to Show the results thus far attained - it does not deal with other investigations carried on by the Survey. It was early learned that North America is divisible into seven transcontinental belts or life zones and a much larger number of minor areas or faunas, each characterized by particular associations of animals and plants. It was then suspected that these same zones and areas, up to the northern limit of profitable agriculture, are adapted to the needs of particular kinds or varieties of cultivated crops, and this has since been fully established. When, therefore, the natural life zones and areas, seemingly of interest only to the naturalist, were found to be natural crop belts and areas, they became at once of the highest importance to the agriculturist. A map show ing. Their position and boundaries, so far as ascertained at the close of the field season of 1897, accompanies this report, and lists of the more Important crops of each belt and its principal subdivisions are here for the first time published. The matter relating to the native animals and plants has been reduced to a fragmentary outline, for the reason that this branch of the subject is of comparatively little inter est to the farmei and fruit grower.

Download or read book Foundations of Biogeography written by Mark V. Lomolino and published by University of Chicago Press. This book was released on 2004-07 with total page 2640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Biogeography provides facsimile reprints of seventy-two works that have proven fundamental to the development of the field. From classics by Georges-Louis LeClerc Compte de Buffon, Alexander von Humboldt, and Charles Darwin to equally seminal contributions by Ernst Mayr, Robert MacArthur, and E. O. Wilson, these papers and book excerpts not only reveal biogeography's historical roots but also trace its theoretical and empirical development. Selected and introduced by leading biogeographers, the articles cover a wide variety of taxonomic groups, habitat types, and geographic regions. Foundations of Biogeography will be an ideal introduction to the field for beginning students and an essential reference for established scholars of biogeography, ecology, and evolution.

Download or read book Ecology of North America written by Eric G. Bolen and published by John Wiley & Sons. This book was released on 1998-02-18 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: From windswept tundra to humid subtropical everglades, fromgracious coniferous forests to austere deserts, North America isblessed with an incredibly diverse array of natural environments,each supporting a unique system of plant and animal life. Thesesystems--also known as biomes--are tightly woven webs of life thathave taken millennia to evolve. This lavishly illustrated bookintroduces readers to this extraordinary array of naturalcommunities and to the subtle interactions of minerals, plants, andanimals that take place within them. Professor Eric Bolen takes a qualitative, intuitive approach to hissubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. Then, biome by biome, he covers the entirety of Canadaand the United States, starting with the tundra of the far northand working his way south and then west to conclude in the desertsand chaparral of southern California. Along the way, he delves intopertinent conservation issues and features fascinating historicalvignettes and original documents detailing human impact on variousenvironments--for instance, the role of John Deere's plow insettling grasslands, and the use of fur records from Hudson's BayCompany. Throughout, he enlivens the text with dozens of exquisitephotographs and illuminating maps, graphs, charts, andtables. Ecology of North America is an ideal first text for studentsinterested in natural resources, environmental science, andbiology, and it is a useful and attractive addition to the libraryof anyone interested in understanding and protecting the naturalenvironment.
Download or read book Geology and Plant Life written by Arthur R. Kruckeberg and published by University of Washington Press. This book was released on 2004 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before any other influences began to fashion life and its lavish diversity, geological events created the initial environments--both physical and chemical--for the evolutionary drama that followed. Drawing on case histories from around the world, Arthur Kruckeberg demonstrates the role of landforms and rock types in producing the unique geographical distributions of plants and in stimulating evolutionary diversification. His examples range throughout the rich and heterogeneous tapestry of the earth's surface: the dramatic variations of mountainous topography, the undulating ground and crevices of level limestone karst, and the subtle realm of sand dunes. He describes the ongoing evolutionary consequences of the geology-plant interface and the often underestimated role of geology in shaping climate. Kruckeberg explores the fundamental connection between plants and geology, including the historical roots of geobotany, the reciprocal relations between geology and other environmental influences, geomorphology and its connection with plant life, lithology as a potent selective agent for plants, and the physical and biological influences of soils. Special emphasis is given to the responses of plants to exceptional rock types and their soils--serpentines, limestones, and other azonal (exceptional) substrates. Edaphic ecology, especially of serpentines, has been his specialty for years. Kruckeberg's research fills a significant gap in the field of environmental science by connecting the conventionally separated disciplines of the physical and biological sciences. Geology and Plant Life is the result of more than forty years of research into the question of why certain plants grow on certain soils and certain terrain structures, and what happens when this relationship is disrupted by human agents. It will be useful to a wide spectrum of professionals in the natural sciences: plant ecologists, paleobiologists, climatologists, soil scientists, geologists, geographers, and conservation scientists, as well as serious amateurs in natural history.

Book excerpt: With the right lifestyle, experts say, chances are that you may live up to a decade longer. What's the prescription for success? National Geographic Explorer Dan Buettner has traveled the globe to uncover the best strategies for longevity found in the Blue Zones: places in the world where higher percentages of people enjoy remarkably long, full lives. And in this dynamic book he discloses the recipe, blending this unique lifestyle formula with the latest scientific findings to inspire easy, lasting change that may add years to your life. Buettner's colossal research effort has taken him from Costa Rica to Italy to Japan and beyond. In the societies he visits, it's no coincidence that the way people interact with each other, shed stress, nourish their bodies, and view their world yields more good years of life. You'll meet a 94-year-old farmer and self-confessed "ladies man" in Costa Rica, an 102-year-old grandmother in Okinawa, a 102-year-old Sardinian who hikes at least six miles a day, and others. By observing their lifestyles, Buettner's teams have identified critical everyday choices that correspond with the cutting edge of longevity research and distilled them into a few simple but powerful habits that anyone can embrace
