Book Description
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.

Book Description
This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.

Book Description
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 Description
Mongolia is an expansive land-locked country, tilted by tectonic forces to the North, that experiences extremes of continental climate. Moisture-carrying wind currents are scarce so that the land has extended highs and lows in its environment. Culturally the people are mostly nomadic, having been sustained for centuries by an economy based on domestic livestock grazing. There is a saying that, `As the noses go, so goes Mongolia', referring to the domesticated grazing noses of sheep, goats, camels, yaks or horses, and wild ungulates such as gazelles. The vast fenceless steppes of Mongolia furnish the vegetation for grazing. With such extremes in climate it is clear that the vegetation must be resilient and dynamic to cope with the dictates of its extremely harsh environments. Pollen profiles from lakes, plant macrofossils and other data over the last 15,000 years show the dynamic nature of Mongolian vegetation. Currently Mongolian society is experiencing much human-driven economic development which increases pressure on its vegetation. The Great Khural Laws of 1995 forcefully addressed such environmental concerns with the expanded establishment of National Reserves and Parks. But continued effort and vigilance must be expended to insure that Mongolian society will continue to be sustained by its vegetation. This book highlights work such as conserving and restoring plant diversity in various ecosystems and makes recommendations for sustaining the vegetation basis of the nomadic Mongolian society.

Book Description
Paleoecological analyses and radiocarbon dating of late-Quaternary sediments from the Queen Charlotte Islands (QCI), northern Vancouver Island, and the continental shelf along the coast of British Columbia reveal substantial changes in vegetation and climate over the last 14,000 14C yr (17,000 cal yr). Extensive portions of the shelf were subaerially exposed at the end of the last glaciation due to lowering of relative sea level by as much as 150 m. AMS radiocarbon ages indicate that the shelf in Hecate Strait was exposed between at least 14,330 and 12,860 14C yr BP. Cyperaceae were locally abundant on the exposed shelf, and fossil Pediastrum algae indicate the presence of freshwater. Interpretation of pollen from late-glacial lake sediments in the southern QCI suggest a succession from herb tundra dominated by Cyperaceae to dwarf shrub tundra including Salix and Empetrum before the development of Pinus contorta woodland. Fossil stomata suggest that Pinus contorta grew locally by 13,040 ± 305 14Cyr BPI and an in situ Pinus stump and associated plant macrofossils demonstrate that forests grew on the adjacent shelf 12,200 14C yr BP. Submerged lake sediments in Logan Inlet record the transition from Pinus contorta woodland to Picea forests about 11,200 14C yr BP. Northern Vancouver Island also supported Pinus contorta woodland during the late-glacial period. Mixed coniferous forests dominated by Pinus contorta with Alnus and pteridophytes occupied the shelf north of Vancouver Island 10,500 14C yr BP. Warming in the early Holocene allowed the northward extension of Pseudoiwga menziesiii, although Picea, Tsuga heterophylla, and Alnus rubra dominated regional forests. By 7500 14C yr BPI shade-tolerant Tsuga heterophylla was the dominant forest tree. A cooler and wetter climate in the late Holocene facilitated development of temperate coniferous rainforest. This research, in combination with earlier studies, demonstrates that portions of the continental shelf were ice-free and vegetated between 14,300 and 9,500 14C yr BP; moderate climatic conditions supported diverse and productive vegetation while adjacent mainland areas remained glaciated. Stratigraphic sequences spanning the last glaciation are still required to confirm the existence of continuous late Pleistocene glacial refugia in the QCI region.

Book Description
During the International Botanical Congress in Edinburgh, 1964, Mrs. 1. M. WEISBACH-J UNK of The Hague discussed a plan for preparation by her publishing company (Dr. W. Junk b.v.) of an international Handbook of Vegetation Science. She proposed a series that should give a comprehensive survey of the varied directions within this science, and their achievements to date as well as their objectives for the future. The challenge of such an enterprise, and its evident value for the further development of vegetation research, induced the undersigned after some consideration to accept the offer of the honorable but also burdensome task of General Editor. The decision was encouraged by a well formulated and detailed outline for the Handbook worked out by the Dutch phytosociolo gists J. J. BARKMAN and V. WESTHOFF. A circle of scholars from numerous countries was invited by the Dr. Junk Publishing Com pany to The Hague in January 1966 to draw up a list of editors and contributors for the parts of the Handbook. The outline and list have served since for the organization of the Handbook, with no need for major change. The different burdens of editors and authors have compelled quite different timings for completion of the individual sections.

Book Description
The analysis of vegetation history is one of the prime objectives for vegetation scientists. In order to understand the recent composition of local floras and plant communities a second knowledge of species com position during recent millenia is essential. With the present concern over climate changes, due to human activities, an understanding of past vegeta tion distribution becomes even more important, since the correlation between climate and vegetation can often be used to predict possible impacts to crops and forests. I was very fortunate to receive the help of Drs. Webb and Huntley to compile this volume on vegetation history. They have collated an impres sive set of papers which together give an account of the vegetation history of most of the continents during the late-Tertiary and Quaternery periods. There are, however, gaps in the coverage achieved, most notably Africa, and Asia apart from Japan. The information in this book will nonetheless certainly be used widely by vegetation scientists for the regions covered in the book and much of it has relevance to the areas not explicitly described. The authors of the individual chapters have done their best to cover recent topics of interest as well as established facts. It is intended that a separate volume will be produced in the near future covering the vegetation history of Africa and Asia. I thank the editors of It fits well into the this volume for their commendable achievement.

Book Description
The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

Book Description
This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.
