Download or read book Aquatic Mites from Genes to Communities written by Heather Proctor and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the ancestral home of chelicerates was the sea, the vast majority of modern species live on land. Most students of spiders and mites also restrict themselves to terrestrial habitats. However, a surprising number of mites (Arachnida: Acari) have returned to a watery existence. Approximately 7000 species from the Mesostigmata, Astigmata, Oribatida, and especially the Prostigmata, now live in marine and freshwater habitats. In Aquatic Mites, a dozen chapters explore the distribution, ecology, behavior, genetics, and evolution of the most diverse of these astonishing arachnids. The results of these studies raise as many interesting questions as they answer, and should provoke more investigations of the biology of freshwater and marine Acari.

It is likely to prove useful as an introduction to the general area, a reference source and for teaching purposes." (The Holocene, November 2008) "If you thought that paleolimnology was just mud, pollen, and diatoms then you will likely be both struck by the complexity of this field of research and grateful that John Smol, FRSC, has described it so clearly and broadly. Simply put, the second edition is an excellent book." ( Journal of Phycology, 2008) “This is a useful text. It provides a good level of detail so that the beginner in this area can appreciate what palaeolimnology can (and cannot) achieve. It goes beyond the simple introduction to provide a detailed understanding of how techniques can be applied ... This is a different take on the usual pollution text and would be of great use to those wishing to understand more from sedimentary records.” Taken from the British Ecological Society’s Teaching Ecology website "John Smol has extensive experience in this field of paleoenvironmental research which he combines well with his excellent written communication skills to produce a text that is easy to read but also thought provoking." (Quaternary Science Reviews, 2009) “The breadth of coverage in this text is impressive.” (Lake and Reservoir Management, 2009) “If I could speak with fluidity and clarity in my lectures as consistently as John Smol writes my students would be very grateful.” (Journal of Paleolimnology, 2009)

Download or read book Global Change in the Holocene written by John Birks and published by Routledge. This book was released on 2014-02-24 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Holocene spans the 11,500 years since the end of the last Ice Age and has been a period of major global environmental change. However the rate of change has accelerated during the last hundred years, due largely to human impacts and this has led to a growing concern for the future of our environmental resources. Global Change in the Holocene demonstrates how reconstructing the record of past environmental change can provide us with essential knowledge about how our environment works and presents the reader with an informed viewpoint from which to project realistic future scenarios. The book brings together key techniques that are widely used in Holocene research, such as radiocarbon dating, dendrochronology and sediment analysis and offers a comprehensive analysis of various archives of environmental change including instrumental and documentary records, corals, lake sediments, glaciers and ice cores. This reference will be an informative and cutting-edge resource for all researchers in the fields of climate change, environmental science, geography, palaeoecology and archaeology.

Download or read book Arctic Climate Impact Assessment Scientific Report written by Arctic Climate Impact Assessment and published by Cambridge University Press. This book was released on 2005-11-07 with total page 1053 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.

Download or read book Quaternary Palaeoecology written by Harry John Betteley Birks and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quaternary Palaeoecology, first published in 1980, discusses the methods and approaches by which Quaternary environments can be reconstructed from the fossil and sedimentary record. This knowledge is of great value as the Quaternary was a time of rapid ecological change, culminating in the present pattern and diversity of ecosystems. It is possible not only to relate these changes to fluctuating climates but also to infer what Man's early influence may have been. The authors describe how past flora and fauna can be reconstructed and how the numbers of fossils can be used to reconstruct past plant and animal populations and communities, and past environments. John Birks has researched in a variety of fields within Quaternary palaeoecology, including pollen analysis and vegetation history, environmental change, past climate reconstruction, and palaeolimnology. Since the 1980s he has introduced and developed numerical methods and quantitative approaches into palaeoecology and palaeolimnology. Besides research in Norway and the UK, he has also worked on palaeoecological problems in Svalbard, Sweden, Finland, Switzerland, Minnesota, and the Yukon. He serves on the editorial boards of several journals and has published widely on many aspects of Quaternary palaeoecology. He is currently Professor of Quantitative Palaeoecology at the University of Bergen, Norway, and University College London, UK. Hilary Birks researches on palaeoecology and past climates primarily through the use of plant macrofossil analysis. She took up the study of plant macrofossils in Minnesota, USA in 1970, where she investigated the modern representation of plants in lake sediments by their fruits and seeds, and also worked on the palaeolimnological record of recent eutrophication and late-glacial palaeoecology. Since then she has extended her macrofossil studies to the late-glacial of Scotland and western Norway, the full-glacial of Beringia (Alaska) and recent changes in North African lakes brought about by human activities. She is Professor of Palaeoecology at the University of Bergen, Norway and teaches palaeoecology at the University of Bergen and University College London, UK.
Download or read book QUATERNARY INSECTS THEIR ENV written by Scott A. Elias and published by Smithsonian Books (DC). This book was released on 1994-03-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Quaternary Insects and Their Environments addresses science's long neglect of fossil insects by demonstrating their immense potential contribution to our knowledge of the paleoenvironmental record of the past 1.7 million years. In this first comprehensive survey of the field, Scott A. Elias recounts the development of Quaternary entomology, reviews the fossil insect record from Quaternary deposits throughout the world, and points to rewarding areas for future research." "Although nineteenth-century scientists believed that Pleistocene insect specimens belonged to extinct taxa, recent research reveals extraordinary species stability: insects responded to climatic change by moving rather than evolving. Elias argues that because of this trait, and the species' relatively refined environmental sensitivity, fossil insects are often more reliable indicators of past environments and climates than the pollen data now commonly used." "Elias discusses the methods used to sample and analyze Quaternary insect fossils as well as the principal characters used in their identification. He describes the mutual climatic range method of paleoclimate interpretation and offers data on distributional shifts and the longevity of modern species through the Quaternary. Using examples from Europe, Greenland, and North America, he reviews the methods employed in archaeological research." "Quaternary Insects and Their Environments is written to be of use and interest to biologists, geologists, environmental scientists, and archaeologists."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Quaternary Ecology written by Hazel R. Delcourt and published by Springer. This book was released on 1991-07-31 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing interest during recent years in vegetation history, long-term climatic changes and the development of biotic communities has resulted in a growth of the literature in this field and has provided an incentive for scientists to use palaeo-ecology concepts to clarify contemporary ecological issues. Quaternary ecology offers the perspective of time, in using natural experiments of the past to evaluate the responses of population, communities and ecosystems to climatic and environmental changes on a time scale extending back over the past two million years of the quaternary period. Examples from the palaeo-ecological literature demonstrate how quaternary ecology interfaces with other branches of ecology, including plant demography, ecological genetics, limnology and landscape ecology.
