Download or read book Foundations of Macroecology written by Felisa A. Smith and published by University of Chicago Press. This book was released on 2014-08-22 with total page 817 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroecology is an approach to science that emphasizes description and explanation of patterns and processes at large spatial and temporal scales. Some liken it to seeing the forest through the trees, an apt ecological use of the proverbial phrase. The term itself was introduced to modern literature by our authors James Brown and Brian Maurer, in a seminal science paper in 1989. We then published books by both of these authors, including Brown s Macroecology in 1995, which quickly traveled to the shelf of classics in ecology, credited with cohering and inspiring a subfield of ecology proper.While macroecology is to many a modern subfield, the large-scale perspective it advocates is implicit in earlier publications. For example, in 1898 de Liocourt studied the influence of management practices on the structure of French fir forests, and characterized the distribution of tree size in three different stands. His findings that in natural areas the number of trees declined exponentially with increasing diameter of the trunk allowed him to draw conclusions about the influence of management practices on tree distribution patterns. Similarly, other classic macroecological patterns including the species-area relationship, latitudinal gradient of species richness, relationship between body size and metabolic rate, species-abundance distribution, and species-body size distribution were identified decades, sometimes even centuries ago. Consequently, despite the scant twenty years that has elapsed since the term was coined, macroecology has a deep and rich history."Foundations of Macroecology" traces and coheres that history, charting an evolutionary trajectory to the rigorous macroecological research landscape science enjoys today. The forty-six papers span eight decades, from 1920 to 1998, and include divergent perspectives of space, time, and taxonomic and habitat affiliation. They are organized into two main parts: Macroecology before Macroecology and Dimensions of Macroecology. The latter is further subdivided into six sections reflecting the subject matter: Allometry and Body Size, Evolutionary Dynamics, Abundance and Distributions, Species Diversity, and Methodological Advances. For each reprinted paper, a macroecologist specializing in that area has written original commentary that places the paper in a broader context and explains why it is foundational. "
Download or read book Pollination Biology written by Leslie Real and published by Elsevier. This book was released on 2012-12-02 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollination Biology reviews the state of knowledge in the field of pollination biology. The book begins by tracing the historical trends in pollination research and the development of the two styles of pollination biology. This is followed by separate chapters on the evolution of the angiosperms; the evolution of plant-breeding systems; the geographical correlations between breeding habit, climate, and mode of pollen transfer; and sexual selection in plants. Subsequent chapters examine the process of sexual selection through gametic competition in Geranium maculatum; the effects of different gene movement patterns on plant population structure; the foraging behavior of pollinators; adaptive nature of floral traits; and competitive interactions among flowering plants for pollinators. The book is designed to provide useful material for advanced undergraduate and graduate students wishing to familiarize themselves with modern pollination biology and also to provide new insights into specific problems for those already engaged in pollination research. The book is intended to be used for both teaching and research.
Download or read book Paleopalynology written by Alfred Traverse and published by Springer Science & Business Media. This book was released on 2007-05-21 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.

This book was released on 2006-04-11 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third volume in the Developments in Paleoenvironmental Research series deals with the major terrestrial, algal, and siliceous indicators used in paleolimnology. Other volumes deal with the acquisition and archiving of lake sediment cores, chronological techniques, and large-scale basin analysis methods (Volume 1), physical and geochemical parameters and methods (Volume 2), zoological techniques (Volume 4), and statistical and data handling methods (Volume 5). These monographs will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments.
Download or read book Killarney Bay written by David S. Brose and published by University of Michigan Press. This book was released on 2021-11-16 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The archaeological site at Killarney Bay, on the northeast side of Georgian Bay in Ontario, Canada, has attracted and mystified archaeologists for decades. The quantities of copper artifacts, exotic cherts, and long-distance trade goods all highlight the importance of the site during its time of occupation. Yet researchers have struggled to date the site or assign it to a particular cultural tradition, since the artifacts and mortuary components do not precisely match those of other sites and assemblages in the Upper Great Lakes. The history of archaeological investigation at Killarney Bay stretches across parts of three centuries and involves field schools from universities in two countries (Laurentian University in Canada and the University of Michigan in the United States). This volume pulls together the results from all prior research at the site and represents the first comprehensive report ever published on the excavations and finds at Killarney Bay. Heavily illustrated.
Download or read book Quaternary Vegetation Dynamics of Europe written by Gerhard Lang and published by Haupt Verlag. This book was released on 2023-06-12 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on palaeoecological studies by many authors, this book gives an overview of the changing history of the European plant cover during the past 2.6 million years, characterized by numerous cold and warm periods. The period of the last 20 000 years (from the Last Glacial Maximum to the present) is presented in detail, with special emphasis on the vegetation dynamics of Europe, the history of selected woody plants, the development of lakes and bogs and the emergence of European cultural landscapes under the influence of humans over thousands of years. In the analysis of the glacial and interglacial periods, the focus is on the different vegetation developments and the progressive impoverishment of the European flora. Further important topics are the spatio-temporal patterns and causes of long-term vegetation changes, the legacies of disturbances and land use on vegetation composition, the role of palaeoecology in nature conservation and its contribution to ecology and environmental sciences. In addition to recent research results, the book provides an overview of the main palaeoecological research methods. It concludes with a summary of the history of palaeoecology and Quaternary botany. For the first time, a detailed synthesis is presented of the many findings on European vegetation dynamics, which are complex and increasingly difficult to summarize. Numerous figures and tables, many of them original, accompany the text. The bibliography includes over 3000 publications. This book is primarily intended for students, researchers and practitioners in plant ecology, palaeoecology, palaeoclimatology, forestry, agronomy, Quaternary sciences, climate sciences, biogeography, geography and archaeology.

Download or read book Alberta s Lower Athabasca Basin written by Brian M. Ronaghan and published by Athabasca University Press. This book was released on 2017-05-24 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, the oil sands region of northeastern Alberta has been the site of unprecedented levels of development. Alberta's Lower Athabasca Basin tells a fascinating story of how a catastrophic ice age flood left behind a unique landscape in the Lower Athabasca Basin, one that made deposits of bitumen available for surface mining. Less well known is the discovery that this flood also produced an environment that supported perhaps the most intensive use of boreal forest resources by prehistoric Native people yet recognized in Canada. Studies undertaken to meet the conservation requirements of the Alberta Historical Resources Act have yielded a rich and varied record of prehistoric habitation and activity in the oil sands area. Evidence from between 9,500 and 5,000 years ago—the result of several major excavations—has confirmed extensive human use of the region’s resources, while important contextual information provided by key geological and palaeoenvironmental studies has deepened our understanding of how the region’s early inhabitants interacted with the landscape. Touching on various elements of this rich environmental and archaeological record, the contributors to this volume use the evidence gained through research and compliance studies to offer new insights into human and natural history. They also examine the challenges of managing this irreplaceable heritage resource in the face of ongoing development. Contributors: Alwynne Beaudoin, Angela Younie, Brian O.K.
