Download or read book The Ice Age written by Jürgen Ehlers and published by Springer Nature. This book was released on 2022-08-19 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nothing new from the Ice Age? Far from it! Barely ten years have passed since the first edition of this book was published, but in that time researchers around the world have developed new methods and published their findings in scientific journals. Consequently, ideas about the course of the Ice Age have changed dramatically. The sequence of the individual ice advances, the direction of ice movement and the direction of meltwater drainage are only partially known, but they can be reconstructed. This book offers in-depth information about the state of the investigations. Ice ages are the periods of the earth's history in which at least one polar region is glaciated or covered by sea ice. Thus, we are currently living in an Ice Age. The present Ice Age is also the period in which humans started to intervene in the shaping of the earth. The results are obvious. Aerial and satellite images can be used to trace the melting of glaciers, but also the decay of the Arctic permafrost, and the clearing of the Brazilian rainforest. This book is a translation of the original German 2nd edition Das Eiszeitalter by Juergen Ehlers, published by Springer-Verlag GmbH Germany, part of Springer Nature, in 2020. The translation was done with the help of artificial intelligence (machine translation by DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and promotes technologies to support the authors.
Download or read book Arctic and Alpine Biodiversity Patterns Causes and Ecosystem Consequences written by F.Stuart III Chapin and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.
Download or read book Alpine Plant Life written by Christian Körner and published by Springer Nature. This book was released on 2021-03-31 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a completely revised, substantially extended treatment of the physical and biological factors that drive life in high mountains. The book covers the characteristics of alpine plant life, alpine climate and soils, life under snow, stress tolerance, treeline ecology, plant water, carbon, and nutrient relations, plant growth and productivity, developmental processes, and two largely novel chapters on alpine plant reproduction and global change biology. The book explains why the topography driven exposure of plants to dramatic micro-climatic gradients over very short distances causes alpine biodiversity to be particularly robust against climatic change. Geographically, this book draws on examples from all parts of the world, including the tropics. This book is complemented with novel evidence and insight that emerged over the last 17 years of alpine plant research. The number of figures – mostly in color – nearly doubled, with many photographs providing a vivid impression of alpine plant life worldwide. Christian Körner was born in 1949 in Austria, received his academic education at the University of Innsbruck, and was full professor of Botany at the University of Basel from 1989 to 2014. As emeritus Professor he is continuing alpine plant research in the Swiss Alps.
Download or read book Devonian Climate Sea Level and Evolutionary Events written by R. T. Becker, 1st and published by Geological Society of London. This book was released on 2016-10-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.
Download or read book African Landscapes written by Michael Bollig and published by Springer Science & Business Media. This book was released on 2009-06-12 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape studies provide a crucial perspective into the interaction between humans and their environment, shedding insight on social, cultural, and economic topics. The research explores both the way that natural processes have affected the development of culture and society, as well as the ways that natural landscapes themselves are the product of historical and cultural processes. Most previous studies of the landscape selectively focused on either the natural sciences or the social sciences, but the research presented in African Landscapes bridges that gap. This work is unique in its interdisciplinary scope. Over the past twelve years, the contributors to this volume have participated in the collaborative research center ACACIA (Arid Climate Adaptation and Cultural Innovation in Africa), which deals with the relationship between cultural processes and ecological dynamics in Africa’s arid areas. The case studies presented here come from mainly Sahara/Sahel and southwestern Africa, and are all linked to broader discussions on the concept of landscape, and themes of cultural, anthropological, geographical, botanical, sociological, and archaeological interest. The contributions in this work are enhanced by full color photographs that put the discussion in context visually.

Download or read book The Great Sand Sea in Egypt written by H. Besler and published by Elsevier. This book was released on 2011-08-30 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Sand Sea in Egypt presents the history of one of the large sand seas in the Sahara, beginning with the sand supply by fluvial transport from partly distant areas and also by local sandstone weathering. It also details sand as carrier of information and shows the possibilities of sedimentary analysis in dealing with such a topic. Simple measurements may supply important information (e.g. salinity measurements). Well known methods can be developed further to answer special questions. A wealth of information can be drawn from especially adapted sedimentological investigations. In the end, bits of information from different analytical sources can be put together to reveal the history of a large sand sea. *Analyzes different geological sources to decipher the history of the Great Sand Sea*Presents the possibilities of sedimentary analysis to interpret the history of an area*Develops well-known methods to further answer special questions
Download or read book Risk Management in a Hazardous Environment written by Michael Bollig and published by Springer Science & Business Media. This book was released on 2010-05-10 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research focus on hazards, risk perception and risk minimizing strategies is relatively new in the social and environmental sciences. This volume by a prominent scholar of East African societies is a powerful example of this growing interest. Earlier theory and research tended to describe social and economic systems in some form of equilibrium. However recent thinking in human ecology, evolutionary biology, not to mention in economic and political theory has come to assign to "risk" a prominent role in predictive modeling of behavior. It turns out that risk minimalization is central to the understanding of individual strategies and numerous social institutions. It is not simply a peripheral and transient moment in a group’s history. Anthropologists interested in forager societies have emphasized risk management strategies as a major force shaping hunting and gathering routines and structuring institutions of food sharing and territorial behavior. This book builds on some of these developments but through the analysis of quite complex pastoral and farming peoples and in populations with substantial known histories. The method of analysis depends heavily on the controlled comparisons of different populations sharing some cultural characteristics but differing in exposure to certain risks or hazards. The central questions guiding this approach are: 1) How are hazards generated through environmental variation and degradation, through increasing internal stratification, violent conflicts and marginalization? 2) How do these hazards result in damages to single households or to individual actors and how do these costs vary within one society? 3) How are hazards perceived by the people affected? 4) How do actors of different wealth, social status, age and gender try to minimize risks by delimiting the effect of damages during an on-going crisis and what kind of institutionalized measures do they design to insure themselves against hazards, preventing their occurrence or limiting their effects? 5) How is risk minimization affected by cultural innovation and how can the importance of the quest for enhanced security as a driving force of cultural evolution be estimated?

Download or read book Under the Mopane Tree Holocene Settlement in Northern Namibia written by Ralf Vogelsang and published by Heinrich Barth Institut. This book was released on 2011-06-20 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main research focus of the Collaborative Research Centre SFB 389 ACACIA (Arid Climate Adaptation and Cultural Innovation in Africa), established at the University of Cologne in 1995, was the interaction between man and arid environments in Africa (KUPER et al. 2007). An important part was played by the diachronic examination of these processes and their development during the Holocene period in Northeast and Southwest Af ri ca. A longterm aim of the interdisciplinary research projects was the comparison of the Holocene settlement history and palaeoecology and the identification of common and divergent developments in both hemispheres. The volume at hand describes some results of the project B4: “Palaeoecology and the Late Holocene Occupation of Northern Namibia”. Regional focus is the northern part of the Kunene Region, the Opuwo District (former Kaokoland), a region in the arid limits between the Namib Desert and the savanna of the interior highlands. Three different scientific fields – namely prehistoric archaeology, archaeobotany and archaeozoology – cooperated in the fieldwork and analysis to reconstruct the prehistoric cultures and environment in the research area during the Holocene time period. Unfortunately, the archaeozoological results are still missing and not included in this book.
Download or read book Why Vulnerability Still Matters written by Greg Bankoff and published by Routledge. This book was released on 2022-04-27 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: We think vulnerability still matters when considering how people are put at risk from hazards and this book shows why in a series of thematic chapters and case studies written by eminent disaster studies scholars that deal with the politics of disaster risk creation: precarity, conflict, and climate change. The chapters highlight different aspects of vulnerability and disaster risk creation, placing the stress rightly on what causes disasters and explaining the politics of how they are created through a combination of human interference with natural processes, the social production of vulnerability, and the neglect of response capacities. Importantly, too, the book provides a platform for many of those most prominently involved in launching disaster studies as a social discipline to reflect on developments over the past 50 years and to comment on current trends. The interdisciplinary and historical perspective that this book provides will appeal to scholars and practitioners at both the national and international level seeking to study, develop, and support effective social protection strategies to prevent or mitigate the effects of hazards on vulnerable populations. It will also prove an invaluable reference work for students and all those interested in the future safety of the world we live in.
