Book Description
The main theme of this book is the reconstruction of past arid environments, with the help of palynology. Palynology was for a long time rarely practised in arid lands due to both technical and conceptual difficulties, mainly centered around poverty in pollen grains and different approaches necessary for treating the spectra, as compared with forested regions. However, recent developments in extraction techniques, along with new concepts applied for analysis of data, show the great potential lying in reconstructing past arid environments, along with a variety of ensuing ramifications. The book provides an update of the state of the art in this branch of science. Firstly, it deals with natural agents relevant to palynology in arid lands, from pollen release by parent plants through transportation, deposition and preservation in various types of rocks. Then it describes sampling strategies, various treatments for extracting microfossils from host rocks, identifying, counting and presenting the results. Concepts and ways for interpretations of results are discussed. There are several case studies, to demonstrate prospects and possibilities in reconstructing late Cenozoic vegetation, climate, transport, environments of deposition, structure, stratigraphy, regional paleogeography and human settlement of past arid environments. A discussion of pre-late Cenozoic arid lands palynology is also included, with examples from the late Paleozoic and early Mesozoic deserts. Each topic is accompanied by photographs and line-drawings. There is an extensive bibliography and subject and author indexes. The book is intended for students and scientists, mainly in palynology, Quaternary sciences, geology, climatology, environmental sciences, paleoclimatology, evolution, biology, geomorphology of arid lands, botany, anthropology and archeology.

Book Description
This introductory volume to a new series on Soil Forensics gives a kaleidoscopic view of a developing forensic expertise. Forensic practitioners and academic researchers demonstrate, by their joint contributions, the extent and complexity of soil forensics. their reports exemplify the broad range of sciences and techniques applied in all stages of forensic soil examinations, from investigations at crime scenes to providing evidence that can be used in court proceedings. Moreover the necessity is depicted of co-operation as a condition for any work in soil forensics between scientists of different disciplines, but no less between scientists and law enforcers.Soils play a role in environmental crimes and liability, as trace evidence in criminal investigations and, when searching for and evaluating, buried human remains. This book shows soil forensics as practiced in this legal context, emerging and solidifying in many countries all over the world, differing in some respects because of differences in legal systems but ultimately sharing common grounds.

Book Description
The succulent and Nama-karoo form part of the arid south-western zone of Africa, a vast region of rugged landscapes and low treeless vegetation. Studies of this unique biome have yielded fascinating insights into the ecology of its flora and fauna. This book, originally published in 1999, is the first to synthesise these studies, presenting information on biogeographic patterns and life processes, form and function of animals and plants, foraging ecology, landscape-level dynamics and anthropogenic influences. Detailed analyses of the factors distinguishing the biota of the Karoo from that of other temperate deserts are given and generalisations about semi-arid ecosystems challenged. The ideas expounded, the ecological principles reviewed, and the results presented are relevant to all those working in the extensive arid and semi-arid regions of the world.

Book Description
A proper understanding of the structural organization of the plant body is essential to any study in plant biology. Experimental studies in vivo and in situ will lead to structural, physiological, and cellular changes of the experimental material. To study macroscopic and microscopic changes, different histological methods and microtechniques can be used as they provide valuable information of the experimental system. In addition, the observed structural changes allow investigators to set hypothesis for further studies based on one’s own observation. Thus, proper selection and utilization of microtechniques are a must for the success of a research program. At present, an up-to-date collection of protocols are not readily available in the literature. The latest work in plant microtechniques was published in 1999 by Ruzin but many others are no longer in print [e.g., Jensen (1964); O’Brien and McCully (1981)]. Furthermore, a majority of published works focus on techniques related to general processing and staining procedures. A comprehensive treatment that encompasses broader applications of microtechniques to other disciplines is lacking [e.g., archeology, wood science, etc.]. There is a need to create a comprehensive volume of botanical methods and protocols which includes traditional and novel techniques that can be used by researchers in plant science and investigators in other disciplines that require plant microtechniques in their research and teaching. This book covers a wide variety of applications and brings them up-to-date to make them understandable and relevant, especially to students using the methods for the first time. It is our intention to create a useful reference for plant histology and related methods that will serve as a foundation for plant scholars, researchers, and teachers in the plant sciences.

Book Description
The research studies included in this Special Issue highlight the fundamental contribution of the knowledge of environmental history to conscious and efficient environment conservation and management. The long-term perspective of the dynamics that govern the human–climate ecosystem is becoming one of the main focuses of interest in biological and earth system sciences. Multidisciplinary bio-geo-archaeo investigations into the underlying processes of human impact on the landscape are crucial to envisage possible future scenarios of biosphere responses to global warming and biodiversity losses. This Special Issue seeks to engage an interdisciplinary dialog on the dynamic interactions between nature and society, focusing on long-term environmental data as an essential tool for better-informed landscape management decisions to achieve an equilibrium between conservation and sustainable resource exploitation.

Book Description
Climate models show that climate change is not a uniform process. Areas of increased temperature are situated near areas of decreased temperature, areas with increased precipitation adjoin areas of drought. This is one of the reasons why climate change is so difficult to detect. Any parameter must be considered and tested locally or regionally and not on an average globally. This book gives an overview of current research methods and results in the different fields of climate research including modelling. In addition, it contains a hemisphere-wide stratigraphic data base with about 80000 species. All paleoclimatic data as well as a state-of-the-art atmospheric circulation model in a PC version are included. So both research and graduate teaching are supported with high-end software running on affordable computers, also in those countries that have no access to Cray super computers. Thus, this book will be of interest to all researchers and scientists in the field of climatology.
