Book Description
The global climate changes that led to the expansion and contraction of high latitude ice sheets during the Quaternary period were associated with equally dramatic changes in tropical environments. These included shifts in vegetation zones, changes in the hydrology and ecology of lakes and rivers, and fluctuations in the size of mountain glaciers and sandy deserts. Until recently it was thought that such changes were triggered by fluctuations in the distribution of polar ice cover. Now there is increasing recognition that the tropics themselves have acted as drivers of global climate change over a range of timescales. The aim of Quaternary Environmental Change in the Tropics is to provide a synthesis of the changes that occurred in tropical terrestrial and marine systems during the Pleistocene and Holocene, complementing data-derived reconstructions with output from state-of-the-art climate models. It is targeted at final-year undergraduate students and research specialists, but will provide an introduction to tropical Quaternary research for a variety of other readers.

Book Description
The tropics provide the key to understanding much biological and Earth science. This is particularly true for the study of landforms, which in higher latitudes suffer great seasonal contrasts in process intensity and type, and which often in the past underwent the dramatic changes of glaciation and periglaciation. Yet studies in the tropics have shown that the legacy of past climate changes is much more dramatic than was formerly believed. This book, first published in 1985, brings together the variety of evidence about such environmental changes, over a variety of timescales, and sets it against the current knowledge of the nature of geomorphic processes in the tropics.

Book Description
What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditionsâ€"or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient lifeâ€"and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening othersâ€"including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative toolsâ€"and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

Book Description
The goal of this book is to provide a current overview of the impacts of climate change on tropical forests, to investigate past, present, and future climatic influences on the ecosystems with the highest biodiversity on the planet.Tropical Rainforest Responses to Climatic Change will be the first book to examine how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis onto ecological processes e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of this book that emerges progressively is the interaction between humans, climate and forest ecology. While numerous books have appeared dealing with forest fragmentation and conservation, none have explicitly explored the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, coupled with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging.

Book Description
Holocene Climate Change and Environment presents detailed, diverse case studies from a range of environmental and geological regions on the Indian subcontinent which occupies the central part of the monsoon domain. This book examines Holocene events at different time intervals based on a new, high-resolution, multi-proxy records (pollen, spores, NPP, diatoms, grain size characteristics, total organic carbon, carbon/nitrogen ratio, stable isotopes) and other physical tools from all regions of India. It also covers new facilities in chronological study and luminescence dating, which have added a new dimension toward understanding the Holocene glacial retreats evolution of coastal landforms, landscape dynamics and human evolution. Each chapter is presented with a unified structure for ease of access and application, including an introduction, geographic details, field work and sampling techniques, methods, results and discussion. This detailed examination of such an important region provides key insights in climate modeling and global prediction systems. - Provides data and research from environmentally and geologically diverse regions across the Indian subcontinent - Presents an integrated and interdisciplinary approach, including considerations of human impacts - Features detailed case studies that include methods and data, allowing for applications related to research and global modeling

Book Description
Founded in 1966, the internationally recognized and acclaimed Series ‘Palaeoecology of Africa’ publishes interdisciplinary scientific papers on landscape evolution and on former environments of the African continent. Beginning with topics such as changes in climate and vegetation cover, the papers expand horizons and interconnections to various types of environmental dynamics from the Cainozoic up to the present; moreover, the aspect of human influence since the Late Quaternary is related to many of the areas studied. Volume 31 presents four comprehensive papers on long- and short-term processes of landscape evolution (geological history, neotectonics and proxy Quaternary alluvia), as well as a recent regional perspective on environmental problems in Southern Cameroon. The book acts as a showcase for successful North-South cooperation and capacity building for empowering African Universities. It is problem oriented and applied, and illustrates how scientific and interdisciplinary cooperation can work. In the framework of the German Research Foundation’s (DFG, Deutsche Forschungsgemeinschaft) funded "Rain Forest Savanna Contact" project (2003-2009) two abbreviated English versions of PhD theses are here published, one by J. Eisenberg on neotectonics and the other by M. Sangen on river sediments in rain forest-savanna transitional zones. Complementary articles are an introduction on geological history, by B. Kankeu et al. and a paper on environmental risks by M. Tchindjang et al., together these complete the results of this joint German-Cameroonian research project. This book will be of interest to all concerned with ecosystems dynamics, tropical forests, savannas and related development problems of Third World countries, especially regional planners, ecologists, botanists, earth scientists and students of the Quaternary (e.g. LGM and Holocene ecosystem dynamics, Global Change). It will be valuable for advanced undergraduates and postgraduates as a reference for new research articles on the topic of long‐term geologic‐tectonic and Quaternary landscape evolution in an up‐to‐now not well explored marginal area of the Western Congo basin.

Book Description
How were the tropical Americas formed? This ambitious volume draws on extensive, multidisciplinary research to develop new views of the geological formation of the isthmus linking North and South America and of the major environmental changes that reshaped the Neotropics to create its present-day marine and terrestrial ecosystems. Recent discoveries show that dramatic changes in climate and ocean circulation can occur very quickly, and that ecological communities respond just as rapidly. Abrupt changes in the composition of fossil assemblages, formerly dismissed as artifacts of a poor fossil record, now are seen as accurate records of swift changes in the composition of ocean communities. The twenty-four contributors use current work in paleontology, geology, oceanography, anthropology, ecology, and evolution to paint this challenging portrait of rapid environmental and evolutionary change. Their conclusions argue for a revision of existing interpretations of the fossil record and the processes—including invading Eurasian peoples—that have produced it.
