Book excerpt: Excerpt from On the Geographic Distribution and Ecological Relations of the Bog Plant Societies of North America The preservation of the bog societies in poorly drained situa tions down to the present time seems to be due (1) to the lower temperatures prevailing there, (2) to the sterile nature of the sub stratum, (3) to the completeness with which the substratum is occupied by the bog plants, and (4) to the fact that most bog habitats are associated with lakes, whose basins must be entirely filled with debris, before the' drainage conditions will be naturally improved and made more favorable for the coming in of other plant societies. To account for the xerophytic character of many of the bog plants, experiments now being carried on seem to indicate that differences of temperature between substratum and air is ade quate. But the presence in many of our bog habitats of swamp species which show no xerophytic adaptations suggests that such xerophytic structures may be unnecessary under present con ditions in this region.

Book excerpt: Excerpt from The Distribution and Physical, and Past-Geological Relations of British North American Plants The species referable to this group, and some of which are confined to Ontario, have, in general, in the United States, a range from Western New England to Wisconsin a stretch of country in breadth about similar to that of Ontario. They occur chiefly west of the Appalachian chain, and do not appear to cross from the forest lands of Wis consm into the prairie country of Minnesota and Dakota. Their northward and northeastward range in Canada is probably limited by the colder climate. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Plant Geography written by Rexford Daubenmire and published by Elsevier. This book was released on 2012-12-02 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Geography: With Special Reference to North America covers main concepts of the two major approaches to plant geography, namely, the floristic plant geography and the ecologic plant geography. Floristic plant geography primarily studies evolutionary divergence, migration, and decline of taxa, as influenced by past events of the earth's history. Ecologic plant geography is an alternative approach to plant geography, which takes plant communities as units having ranges to be interpreted, dominated by sociologic and physiologic, rather than phylogenetic and historic considerations. Under the floristic plant geography part, topics covered include interrelations among floristic plant geography, taxonomy, and geology; the relation between plant dissemination and migration; evidence of the dynamic character of plant ranges; and migratory route. After a brief introduction to the evolution of North and South America vegetation, the book discusses the ecologic plant geography section that focuses on various vegetation regions in North America, including Tundra, subarctic-subalpine forest, temperate mesophytic, xerophytic forest, and chaparral and steppe regions and temperate affinity forests in Middle America. Other regions examined include the desert and marine regions, as well as the microphyllous woodland, tropical savanna, rain forest, and tropical alpine. With great information on geologic history of each vegetation unit and paleontology, this book will be helpful to paleobotanists, historical geologists, and taxonomists.
Download or read book Essay on the Geography of Plants written by Alexander von Humboldt and published by University of Chicago Press. This book was released on 2010-07-15 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The legacy of Alexander von Humboldt (1769–1859) looms large over the natural sciences. His 1799–1804 research expedition to Central and South America with botanist Aimé Bonpland set the course for the great scientific surveys of the nineteenth century, and inspired such essayists and artists as Emerson, Goethe, Thoreau, Poe, and Church. The chronicles of the expedition were published in Paris after Humboldt’s return, and first among them was the 1807 “Essay on the Geography of Plants.” Among the most cited writings in natural history, after the works of Darwin and Wallace, this work appears here for the first time in a complete English-language translation. Covering far more than its title implies, it represents the first articulation of an integrative “science of the earth, ” encompassing most of today’s environmental sciences. Ecologist Stephen T. Jackson introduces the treatise and explains its enduring significance two centuries after its publication.

Download or read book Plants and People written by Thomas R. Vale and published by . This book was released on 1982 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: General questions of vegetation change and the relationship between natural and human causes of plant disturbance are examined. The themes presented were treated by the author in a semester-long, college-level geography course. The book might be used as an outline for professors wishing to develop such a course, as a text for students, or as a supplemental reference for a more general course in biogeography or related fields. There are six chapters. Chapter 1 examines factors influencing vegetation and disturbance as a vegetation factor. Vegetation change is the focus of the second chapter. Chapter 3 discusses human impacts on vegetation, looking at changes in fire regimes, livestock grazing, logging, trampling, off-road vehicles, air pollution, construction activity, altered biota, abandonment of agricultural land, and purposeful manipulation. The effects of altered vegetation on environmental systems are examined in the fourth chapter. Historical and ecological sources for studying vegetation change are dealt with in chapter 5. The concluding chapter discusses vegetation change and human purpose. A bibliography is included. (RM)

Available in PDF, EPUB and Kindle. Book excerpt: The European explorers who first visited the Northwest Coast of North America assumed that the entire region was virtually untouched wilderness whose occupants used the land only minimally, hunting and gathering shoots, roots, and berries that were peripheral to a diet and culture focused on salmon. Colonizers who followed the explorers used these claims to justify the displacement of Native groups from their lands. Scholars now understand, however, that Northwest Coast peoples were actively cultivating plants well before their first contact with Europeans. This book is the first comprehensive overview of how Northwest Coast Native Americans managed the landscape and cared for the plant communities on which they depended. Bringing together some of the world's most prominent specialists on Northwest Coast cultures, Keeping It Living tells the story of traditional plant cultivation practices found from the Oregon coast to Southeast Alaska. It explores tobacco gardens among the Haida and Tlingit, managed camas plots among the Coast Salish of Puget Sound and the Strait of Georgia, estuarine root gardens along the central coast of British Columbia, wapato maintenance on the Columbia and Fraser Rivers, and tended berry plots up and down the entire coast. With contributions from ethnobotanists, archaeologists, anthropologists, geographers, ecologists, and Native American scholars and elders, Keeping It Living documents practices, many unknown to European peoples, that involve manipulating plants as well as their environments in ways that enhanced culturally preferred plants and plant communities. It describes how indigenous peoples of this region used and cared for over 300 different species of plants, from the lofty red cedar to diminutive plants of backwater bogs.
