Book Synopsis Ecological Regions of North America by :
Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Ecology of North America by : Eric G. Bolen
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.
Book Synopsis The Great American Biotic Interchange by : Alberto Luis Cione
Download or read book The Great American Biotic Interchange written by Alberto Luis Cione and published by Springer. This book was released on 2015-04-24 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the “Great American Biotic Interchange” (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South America and continues today. The major phases of mammalian dispersal occurred from the Latest Pliocene (Marplatan Age) to the Late Pleistocene (Lujanian Age). The most important and richest localities of Late Miocene-Holocene fossil vertebrates of South America are those of the Pampean region of Argentina. There are also several Late Miocene and Pliocene localities in western Argentina and Bolivia. Other important fossils have been collected in localities of Pleistocene age outside Argentina: Tarija (Bolivia), karstic caves of Lagoa Santa and the recently explored caves of Tocantins (Brasil), Talara (Perú), La Carolina (Ecuador), Muaco (Venezuela), and Cueva del Milodon (Chile), among others. The book discusses basic information for interpreting the GABI such as taxonomic composition (incorporating the latest revisions) at classical and new localities for each stage addressing climate, environments, and time boundaries for each stage. It includes the chronology and dynamics of the GABI, the integration of South American mammalian faunas through time, the Quaternary mammalian extinctions and the composition of recent mammalian fauna of the continent.

Book Synopsis Environmental Versus Geological Barriers in the Great American Biotic Interchange by : Carlos Alberto Jiménez Rivillas
Download or read book Environmental Versus Geological Barriers in the Great American Biotic Interchange written by Carlos Alberto Jiménez Rivillas and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological closure of the Isthmus of Panama (IP) precipitated one of the greatest biogeographic events of the Cenozoic that indelibly changed composition of biotic communities in South and North America. The precise timing of uplift and final closure of the IP continues to be a topic of intense debate in geology and evolutionary biology. The traditional or Young Isthmus model states that the definitive closure of the IP occurred between 4 and 3 million years ago (Ma). The more recently proposed Old Isthmus model states that the IP was completed during the middle Miocene (15 to 13 Ma). Regardless of the closure data, the fossil record makes clear that at 2.7 Ma began the Great American Biotic Interchange (GABI), a massive interchange of mammalian lineages, many affiliated with dry and open environments. For the Old Isthmus hypothesis to be viable, one must posit the existence of some non-oceanic barrier that delayed the interchange between continents for some 10 million years. Here, we tested the hypothesis that an environmental barrier in the form of a humid, closed-canopy forest was present on the IP prior to the Pleistocene interchange and glacial cycling. Scant paleoenvironmental data are available from the Neogene IP, so here we test our hypothesis indirectly using comparative phylogeography of 69 species of anurans by reconstructing their environmental affinities and estimating the timing of interchange between continents for each lineage. We found that frog species with a preference for dry and open environments all moved between continents after 3 Ma, while the mean date of interchange for those associated with humid forests was 6.1 Ma, including some more recently than 3 Ma. Semi-arid species crossed significantly later than humid forest species, as predicted by the hypothesis that a humid, closed-canopy forest barrier existed during the Late Miocene.

Book Synopsis Systematics, Historical Ecology, and North American Freshwater Fishes by : Richard L. Mayden
Download or read book Systematics, Historical Ecology, and North American Freshwater Fishes written by Richard L. Mayden and published by . This book was released on 1992 with total page 969 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book addresses the current need for a holistic approach in comparative and evolutionary biology and offers numerous applications of the modern methods of phylogenetic systematics and historical ecology, using the North American fish fauna as its case study. This major synthesis, the first published work of its kind, provides a theoretical and methodological foundation for future studies in ichthyology, evolutionary biology, and other fields of comparative biology." "Several introductory pieces present major statements of general principles, detailed examinations of the diversity and distributions of North American freshwater fishes, and what is known of their systematic relationships. The rest of the volume's 30 papers then contribute new phylogenetic hypotheses for a significant number of taxa. Along the way, the reader is introduced to the principles, first, of phylogenetic systematics - the reconstruction of evolutionary or ancestor-descendant relationships of groups of organisms on the basis of heritable traits - and, second, of historical ecology - a comprehensive research program that links systematics with many areas of comparative biology. Together, the two allow for the formulation of direct and testable hypotheses regarding the evolution of species and their attributes, interspecies interactions, and the formation and persistence of biotic communities. Without these methods that incorporate "historical controls," our estimates of history for all areas of biology are inefficient, indirect, and worst of all, untestable." "This book focuses on North American freshwater fishes not only because the 42 contributors know them so well but also because this highly diverse fauna is well known in so many important aspects (diversity, species distributions, life histories) relevant to evaluating general applications of the new paradigms of systematics and historical ecology. Many other faunas present interesting biotas appropriate for the preparation of a similar piece of work, but no other fauna can claim as complete a knowledge base." "The theme articulated throughout the book underscores the Darwinian proposition of descent with modification. The biological information particular to the North American freshwater fish fauna establishes an invaluable foundation for understanding diversification and advancing education and research. Moreover, the methods, theories, and empirical data presented serve as essential resources for comparative and evolutionary research programs applicable to any biota or taxonomic grouping." "The book includes some 200 illustrations, 60 tables, 10 appendixes, and comprehensive taxonomic and subject indexes."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
