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.

Book excerpt: Excerpt from Life Zones and Crop Zones of New Mexico Stock raising-forestry, and mining are being put on a scientific basis. Graded cattle have almost entirely taken the place of the Texas longhorn; valuable horses are superseding the cayuse; the' grade of sheep in many places is being greatly improved; lumbering is coming under Government control that, while utilizing the forests, will perpetuate them; and mining methods are being improved so that low - grade ores are worked at a profit. Certain sections are becoming famous for the flavor and quality of fruits, which develop and mature to their greatest perfection under the combined influence of an arid atmosphere and the proper control of moisture in the soil. Various forage crops, grains, and vegetables have proved signally successful in restricted areas, and if the best results of a steadily developing agriculture, are to be obtained the boundaries of the areas of approximately uniform agricultural char acter should be mapped and be made known.1913.

Two dimensional climatic provinces conclusion literature references. The differences in plant life which exist between distant or even between nearby localities must have come under the notice of man in the earliest semicivilized stages of his existence. Human depend ence upon the products of the vegetable kingdom has served to maintain throughout all historic time a Vivid realization of the vegetational differences encountered with changes of latitude, alti tude, and proximity to the sea. The later stages of modern civiliza tion have done extremely little to liberate man from his dependence upon plants, although the development of methods for the preserva tion and transportation of food has given him greater freedom of movement into the jungle, the polar regions, the desert, and the modern city. Many of the activities of the last 150 years have been such as to increase our interest in the distribution of plants and in the nature of the plant populations which characterize different regions, different soils, or different topographic situations. Innumerable bands of ex plorers and collectors have penetrated all parts of the world, bringing back materials upon which we have been able to base a knowledge of the flora and the larger aspects of the vegetation of all but the most inaccessible portions of the globe. The extensive introduction of economic and ornamental plants into new regions and even into new continents has awakened an interest in the possibility of still further introductions and in a study of the causes of the success or failure of such as have been made. The increasing value of all the products Of the forest has led to the planting of trees on a large scale within their native regions and to the experimental introduction of trees from dis tant countries, as well as to attempts to improve natural forest stands. The increasing population of the world has augmented the value of its agricultural lands and has given importance to the study of the proper ties of the soil in their relation to plants. The search for new agri cultural regions and for cr0p plants adapted to the conditions in newly settled areas has led to an interest in natural plant growth as an index of the most promising soils or of the most suitable crops to be cultivated.

This book was released on 2017-10-27 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Description of the Ecoregions of the United States Public land management agencies are increasingly involved in regional and national long-range planning and in efforts to classify all lands according to their capabilities and availability to produce goods and services in a balanced national program. During the past few years, these agencies have generally recognized the need for a comprehensive system for classifying ecosystems as an aid to achieving quality land management. Regional variations in climate, vegetation, and landform are important in the development of ecosystems; and, often, different regions have very different management problems. For this reason, it is important to recognize regional differences at the highest level in the classification. This regionalization facilitates (1) planning at the national level, where it is necessary to study management problems and potential solutions on a regional basis; (2) organization and retrieval of data gathered in a resource inventory; and (3) interpreta tion of inventory data, including differences in indicator plants and animals among regions.

The Mammals To secure definite information regarding the distribution, abun dance, and economic relations of the birds and mammals and at the same time to study the distribution of the plant life of this region, a biological survey of Alabama was carried on during a period of several years. From these investigations, and with the aid of Mohr's detailed report on the plant life,1 it has been possible to define the ranges of the mammals and birds and the boundaries of the natural life zones within the State. The report on the bird life has been prepared and tentative arrangements made for its publica tion; the reports on life zones and on the mammals are presented herewith.

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: Excerpt from The Areas of the United States, the States, and the Territories The following report aims to give in brief form such advance results as are available from a detailed investigation of the geology of the Goldfield and Bullfrog districts carried out during the autumn and winter of 1905 - 6. Complete reports on these districts are now in preparation and will be published as soon as possible. In the present bulletin are included also such reconnaissance notes as were made on outlying districts visited in connection with the principal work of the field season. Messrs. W. H. Emmons and G. H. Garrey, who had efficiently assisted in the work throughout the season, were instructed at its close to visit the Manhattan district, mainly for the purpose of ascertaining the area that should be included in future mapping and study of this new gold field. Their notes on the geology of the dis trict are published as a separate section in this report. During the summer and autumn of 1905 a topographic map, covering square miles of southern Nevada and including the Goldfield and Bullfrog districts, was made by Messrs. R. H. Chapman and B. D. Stewart, topographers. A copy of this map accompanies this report (pl. I). Mr. S. H. Ball was attached to Mr. Chapman's party as geologist, and the results of his reconnaissance of the whole region, made under the writer's general supervision, will be published as a separate bulletin (no.
