Book Synopsis Paleoecology of Forest Environments Through Time by : Larisa R. G. DeSantis
Download or read book Paleoecology of Forest Environments Through Time written by Larisa R. G. DeSantis and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Understanding the paleoecology of forest environments is critical to comprehending the context of mammalian evolution, particularly of forest-dwelling taxa. Significant work has helped clarify the timing and consequences of the evolution of grassland biomes in North America. In contrast, the paleoecology of forest environments during the late Cenozoic in southeastern North America requires further study. Therefore, my dissertation aims to understand the ecology of forest environments using stable isotopes of mammalian herbivores.
Book Synopsis Long-Term Forest Dynamics of the Temperate Zone by : Paul A. Delcourt
Download or read book Long-Term Forest Dynamics of the Temperate Zone written by Paul A. Delcourt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis presented in this volume is a direct outgrowth of our ten-year FORMAP Project (Forest Mapping Across Eastern North America from 20,000 yr B.P. to the Present). Many previous research efforts in paleoecology have used plant-fossil evidence as proxy information for primarily geologic or climatic reconstructions or as a bio stratigraphic basis for correlation of regional events. In contrast, in this book, we deal with ecological questions that require a holistic perspective that integrates the interactions of biota with their dynamically changing environments over time scales up to tens of thousands of years. In the FORMAP Project, our major research objective has been to use late-Quaternary plant-ecological data sets to evaluate long-term patterns and processes in forest de velopment. In order to accomplish this objective, we have prepared subcontinent-scale calibrations that quantitatively relate the production and dispersal of arboreal pollen to dominance in the vegetation for the major tree types of eastern North America. Quantification of pollen-vegetation relationships provides a basis for developing quan titative plant-ecological data sets that allow further ecological analysis of both individual taxa and forest communities through time. Application of these calibrations to fossil pollen records for interpreting forest history thus represents a fundamental step beyond traditional summaries based upon pollen percentages.
Book Synopsis Paleontology in Ecology and Conservation by : Julien Louys
Download or read book Paleontology in Ecology and Conservation written by Julien Louys and published by Springer Science & Business Media. This book was released on 2012-04-25 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fossil record contains unique long-term insights into how ecosystems form and function which cannot be determined simply by examining modern systems. It also provides a record of endangered species through time, which allow us to make conservation decisions based on thousands to millions of years of information. The aim of this book is to demonstrate how palaeontological data has been or could be incorporated into ecological or conservation scientific studies. This book will be written by palaeontologists for modern ecologists and conservation scientists. Manuscripts will fall into one (or a combination) of four broad categories: case studies, review articles, practical considerations and future directions. This book will serve as both a ‘how to guide’ and provide the current state of knowledge for this type of research. It will highlight the unique and critical insights that can be gained by the inclusion of palaeontological data into modern ecological or conservation studies.

Book Synopsis Methods in Paleoecology by : Darin A. Croft
Download or read book Methods in Paleoecology written by Darin A. Croft and published by Springer. This book was released on 2018-10-27 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the reconstruction of past ecosystems and provides a comprehensive review of current techniques and their application in exemplar studies. The 18 chapters address a wide variety of topics that span vertebrate paleobiology and paleoecology (body mass, postcranial functional morphology, evolutionary dental morphology, microwear and mesowear, ecomorphology, mammal community structure analysis), contextual paleoenvironmental studies (paleosols and sedimentology, ichnofossils, pollen, phytoliths, plant macrofossils), and special techniques (bone microstructure, biomineral isotopes, inorganic isotopes, 3-D morphometrics, and ecometric modeling). A final chapter discusses how to integrate results of these studies with taphonomic data in order to more accurately characterize an ancient ecosystem. Current investigators, advanced undergraduates, and graduate students interested in the field of paleoecology will find this book immensely useful. The length and structure of the volume also makes it suitable for teaching a college-level course on reconstructing Cenozoic ecosystems.
Book Synopsis Terrestrial Ecosystems Through Time by : Anna K. Behrensmeyer
Download or read book Terrestrial Ecosystems Through Time written by Anna K. Behrensmeyer and published by University of Chicago Press. This book was released on 1992-08-15 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breathtaking in scope, this is the first survey of the entire ecological history of life on land—from the earliest traces of terrestrial organisms over 400 million years ago to the beginning of human agriculture. By providing myriad insights into the unique ecological information contained in the fossil record, it establishes a new and ambitious basis for the study of evolutionary paleoecology of land ecosystems. A joint undertaking of the Evolution of Terrestrial Ecosystems Consortium at the National Museum of Natural History, Smithsonian Institution, and twenty-six additional researchers, this book begins with four chapters that lay out the theoretical background and methodology of the science of evolutionary paleoecology. Included are a comprehensive review of the taphonomy and paleoenvironmental settings of fossil deposits as well as guidelines for developing ecological characterizations of extinct organisms and the communities in which they lived. The remaining three chapters treat the history of terrestrial ecosystems through geological time, emphasizing how ecological interactions have changed, the rate and tempo of ecosystem change, the role of exogenous "forcing factors" in generating ecological change, and the effect of ecological factors on the evolution of biological diversity. The six principal authors of this volume are all associated with the Evolution of Terrestrial Ecosystems program at the National Museum of Natural History, Smithsonian Institution.
Book Synopsis Quaternary Ecology by : Hazel R. Delcourt
Download or read book Quaternary Ecology written by Hazel R. Delcourt and published by Springer. This book was released on 1991-07-31 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing interest during recent years in vegetation history, long-term climatic changes and the development of biotic communities has resulted in a growth of the literature in this field and has provided an incentive for scientists to use palaeo-ecology concepts to clarify contemporary ecological issues. Quaternary ecology offers the perspective of time, in using natural experiments of the past to evaluate the responses of population, communities and ecosystems to climatic and environmental changes on a time scale extending back over the past two million years of the quaternary period. Examples from the palaeo-ecological literature demonstrate how quaternary ecology interfaces with other branches of ecology, including plant demography, ecological genetics, limnology and landscape ecology.
Book Synopsis Foundations of Paleoecology by : S. Kathleen Lyons
Download or read book Foundations of Paleoecology written by S. Kathleen Lyons and published by University of Chicago Press. This book was released on 2019-12-13 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 99% of all life that has ever existed is extinct. Fortunately, these long dead species have left traces of their lives and interactions with other species in the rock record that paleoecologists use to understand how species and ecosystems have changed over time. This record of past life allows us to study the dynamic nature of the Earth and gives context to current and future ecological challenges. This book brings together forty-four classic papers published between 1924 and 1999 that trace the origins and development of paleoecology. The articles cross taxonomic groups, habitat types, geographic areas, and time and have made substantial contributions to our knowledge of the evolution of life. Encompassing the full breadth of paleoecology, the book is divided into six parts: community and ecosystem dynamics, community reconstruction, diversity dynamics, paleoenvironmental reconstruction, species interaction, and taphonomy. Each paper is also introduced by a contemporary expert who gives context and explains its importance to ongoing paleoecological research. A comprehensive introduction to the field, Foundations of Paleoecology will be an essential reference for new students and established paleoecologists alike.

Book Synopsis The Social Lives of Forests by : Susanna B. Hecht
Download or read book The Social Lives of Forests written by Susanna B. Hecht and published by University of Chicago Press. This book was released on 2014-03-04 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests are in decline, and the threats these outposts of nature face—including deforestation, degradation, and fragmentation—are the result of human culture. Or are they? This volume calls these assumptions into question, revealing forests’ past, present, and future conditions to be the joint products of a host of natural and cultural forces. Moreover, in many cases the coalescence of these forces—from local ecologies to competing knowledge systems—has masked a significant contemporary trend of woodland resurgence, even in the forests of the tropics. Focusing on the history and current use of woodlands from India to the Amazon, The Social Lives of Forests attempts to build a coherent view of forests sited at the nexus of nature, culture, and development. With chapters covering the effects of human activities on succession patterns in now-protected Costa Rican forests; the intersection of gender and knowledge in African shea nut tree markets; and even the unexpectedly rich urban woodlands of Chicago, this book explores forests as places of significant human action, with complex institutions, ecologies, and economies that have transformed these landscapes in the past and continue to shape them today. From rain forests to timber farms, the face of forests—how we define, understand, and maintain them—is changing.
Book Synopsis Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington by : Daniel G. Gavin
Download or read book Late Pleistocene and Holocene Environmental Change on the Olympic Peninsula, Washington written by Daniel G. Gavin and published by Springer. This book was released on 2014-11-25 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors’ studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in ‘refugia’: locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).
Book Synopsis Climate Change and Human Impact on the Landscape by : F. M. Chambers
Download or read book Climate Change and Human Impact on the Landscape written by F. M. Chambers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: I am pleased to present this volume of invited reviews and research case studies, produced to mark the retirement of Professor A. G. Smith - one of the leading researchers in Holocene palaeoecology. A. G. Smith took his first degree at the University of Sheffield, graduating in 1951 with a first-class honours degree in Botany. His doctorate was awarded in 1956 for a study in late-Quaternary vege tational history, based in the Sub-Department of Quaternary Research at the University of Cambridge, under the supervision of the late Sir Harry Godwin, FRS. He then researched and taught at Queen's University, Belfast, from 1954, leading the Nuffield Quaternary Research Unit there, becoming Co-Director of the Palaeoecology Laboratory from 1964. He was appointed Professor and Head of the Department of Botany (later, Plant Science) at University College, Cardiff, in 1973, and retired from the School of Pure and Applied Biology at the renamed University of Wales College, Cardiff, in August 1991. Although his principal interests have been concerned with the post-glacial environmental history of the British Isles, Professor Smith has significantly in fluenced many researchers elsewhere in their interpretation of biological and other evidence for human modification of the natural environment.
