Available in PDF, EPUB and Kindle. Book excerpt: Les zones humides (ZH) alluviales constituent des secteurs à forte valeur écologique etpatrimoniale. Pour comprendre et prédire l'évolution à long terme de ces zones, en particulierface aux changements globaux, il apparaît primordial de traduire les perturbationshydrologiques attendues en termes de perturbations biologiques, afin d'estimer lesconséquences potentielles de ces changements pour la biodiversité et le fonctionnement globalde ces écosystèmes. Cette thèse s'articule donc autour de deux objectifs: proposer un modèleconceptuel de fonctionnement écologique des ZH soumises à des assèchements saisonniers etestimer la vulnérabilité écologique de communautés faunistiques vivant dans ces ZH, enconsidérant conjointement les peuplements benthiques et interstitiels (principalementCrustacés).Nos résultats démontrent que la morphologie des ZH (eau relativement courante, eaustagnante, apports phréatique) et leurs modes d'assèchement (formation de mouilles isoléesou assec complet) sont essentiels dans la structuration des communautés microbiennes etd'invertébrés et dans la réponse saisonnière de la biodiversité et des processus écologiques.L'intensification probable des étiages et des assèchements augmentera l'hétérogénéité spatialeet temporelle des habitats et leur richesse spécifique mais réduira la biodiversité globale desplaines alluviales (disparition des espèces rares). Ces étiages plus sévères modifieront lesprocessus écologiques, diminuant le recyclage de la matière organique et la qualité des eauxsuperficielles. Les recherches futures devraient s'orientées vers des stratégies et des moyensefficaces pour garantir la durabilité écologique des ZH.

Book excerpt: This book focuses on two complementary time-scales, the Holocene (approximately the last 11,500 years) and the last glacial-interglacial cycle (approximately the last 130,000 years) to synthesize evidence of climate variability at the regional and continental scale across Europe and Africa. This is the first examination of historical climate variations at such a scale, and thus sets a benchmark for future research.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

This book was released on 2007 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
