Download or read book Fifty Years After the Homage to Santa Rosalia Old and New Paradigms on Biodiversity in Aquatic Ecosystems written by Luigi Naselli-Flores and published by Springer. This book was released on 2015-03-21 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the fiftieth anniversary of publication of one of the landmarks of the modern ecological thought: the “Homage to Santa Rosalia or why are there so many kinds of animals” by George Evelyn Hutchinson. Published in 1959 in the journal “The American Naturalist”, this article has been the engine which have moved most of the ecological research on biodiversity in the last half a century. Hutchinson starts his article by telling the legend of Santa Rosalia, a hermit who died in the second half of the XIII century and who spent the last years of her life in a cave nearby a pond. In this pond Hutchinson collected two species of aquatic insects and took the inspiration to explore the reasons why life is present on our Planet in such amazing variety of forms. This article thus inaugurated the season of research on biodiversity. Researchers and students in the field of ecology are the readers to whom this book is mainly addressed but also those involved in the history of Science will find in this book useful information. Issued in 2010, which has been declared “international Year of Biodiversity” by the United Nations, this book is also a tribute to the biological diversity allowing, enriching and sustaining human life.
Download or read book Twelfth International Diatom Symposium written by Herman van Dam and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Twelfth International Diatom Symposium stressed how diatoms can be used to assess the human impact on natural waters, without neglecting other important fields of research. As the frustules of many diatom species are relatively resistant to dissolution they are preserved in freshwater and marine sediments and provide a record of past environments on earth. In past decades they have been successfully used to reconstruct changes in water bodies evoked by changes in salinity, acidification and eutrophication. In the last few years diatom-inferred predictions of environmental variables have become much more quantitative. In the most recent research reports the strong separation between palaeolimnological and neolimnological diatom research is fading, as palaeolimnologists are increasingly using modern calibration sets to infer past states of the environment. This quantitative approach is also very suitable for prediction of future changes in the biota of surface waters. Also ecological changes due to climatic modification have been investigated more thoroughly recently. A very important new research topic is the occurrence of toxic diatoms, particularly along the coasts of North America. These proceedings are intended to be a balanced view of such modern developments in diatom research. They should also be of interest to non-specialists in diatoms, who can use the results of diatom research as a tool in a more general taxonomic, ecological and geological context.
Download or read book Ancient Lakes Biodiversity Ecology and Evolution written by Andrew Rossiter and published by Academic Press. This book was released on 2000-08-22 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scattered over several continents, the ancient lakes of the world have a unique uninterrupted history dating back beyond 100,000 years. Ancient lakes are, in effect, aquatic islands in which a complex of ecology, genetics and evolutionary constraints have shaped in isolation their biotas over hundreds of thousands to millions of years. The diverse faunas achieve some of the highest levels of diversity known to any habitat, offering unique opportunities as 'natural laboratories' for studying the mechanisms of evolution and speciation in situ. This internationally authored volume contains the latest research results and theories to emerge from a diverse range of studies in these lakes. Containing exciting new findings in the ecology, evolution and systematic studies of ancient lake biotas together with many suggested areas for future research, it will be essential reading for all those with a general interest in ecology, evolution and natural history. In this volume expert scientists present the latest results and perspectives from their research on the organisms of the ancient lakes. Diverse in its taxonomic coverage and themes, and international in its authorship and coverage, Ancient Lakes will appeal to all biologists interested in evolution, ecology and biodiversity. Ancient lakes are increasingly recognised as important models of evolution and speciation This volume presents a diverse range of exciting new hypotheses and perspectives on ancient lake biotas Information is included on Russian and Chinese faunas, available in English here for the first time
Download or read book Freshwater Diatoms from Northern Qu bec and Labrador Canada written by Marie-Andrée Fallu and published by Berlin : J. Cramer. This book was released on 2000 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The freshwater diatom flora from arctic and subarctic regions of North America remains poorly known. The aim of this investigation is to improve our knowledge of diatoms in lakes from eastern subarctic Canada, and to provide a stronger foundation for the use of diatoms in limnological and palaeolimnological studies. To this end, we analysed the modern diatom assemblages in surficial sediments from 123 lakes in northern Québec and Labrador. The two study transects in Jamésie-Hudsonie (data set including 59 lakes and 38 environmental variables) and in Québec-Labrador (data set consisting of 64 lakes and 29 environmental variables) extend over a vast area from the boreal forest in the south to arctic tundra conditions in the north. Of a total of 516 diatom taxa in the Jamésie-Hudsonie data set, 218 species were used for the development of a transfer function for the reconstruction of dissolved organic carbon (DOC). In the Québec.Labrador data set, two inference models were developed for the reconstruction of water colour and alkalinity based on 128 of 303 diatom taxa. The majority of taxa belonging to this surprisingly species-rich boreal-subarctic diatom flora are illustrated in photographic plates, accompanied by a short description of the distribution of each taxon.
Download or read book The Archaeological and Forensic Applications of Microfossils A Deeper Understanding of Human History The Archaeological and Forensic Applications of Microfossils written by M. Williams and published by Geological Society of London. This book was released on 2017-06-16 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microfossils are an abundant component of the sedimentary rock record. Their analysis can reveal not only the environments in which the rocks were deposited, but also their age. When combined, the spatial and temporal distribution patterns of microfossils offer enormous utility for archaeological and forensic investigations. Their presence can act as a geological ‘fingerprint’ and the tiniest fragment of material, such as a broken Iron Age potsherd, can contain a microfossil signature that reveals the geographical source of the materials under investigation. This book explores how microfossils are employed as tools to interpret human society and habitation throughout history. Examples include microfossil evidence associated with Palaeolithic human occupation at Boxgrove in Sussex, alongside investigations into human-induced landscape change during the Holocene. Further examples include the use of microfossils to provenance the source materials of Iron Age ceramics, Roman mosaics and Minoan pottery, in addition to their application to help solve modern murder cases, highlighting the diverse applications of microfossils to improving our understanding of human history.

Download or read book The East African Great Lakes Limnology Palaeolimnology and Biodiversity written by Eric O. Odada and published by Springer Science & Business Media. This book was released on 2006-03-09 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second International Symposium on the East African Lakes was held from 10-15 January 2000 at Club Makokola on the southern shore of Lake Malawi. The symposium was organized by the International Decade for the East African Lakes (IDEAL), a research consortium of African, European and North American scientists interested in promoting the investigations of African Great Lakes as archives of environmental and climatic dynamics. Over one hundred African, European and North American scientists with special expertise in the tropical lakes participated in the symposium which featured compelling presentations on the limnology, climatology, palaeoclimatology and biodiversity of the East African Lakes. It is their papers that comprise this book. The large lakes of East Africa are important natural resources that are heavily utilized by their bordering countries for transportation, water supply, fisheries, waste disposal, recreation and tourism. The lakes are unique in many ways: they are sensitive to climatic change and their circulation dynamics, water-column chemistry and biological complexity differ significantly from large lakes at higher latitudes; they have long, continuous, high resolution records of past climatic change; and they have rich and diverse populations of endemic organisms. These unique properties and the significance of the palaeolimnological records demand and attract research interest from around the world.
Download or read book Patterns and Processes of Speciation in Ancient Lakes written by Thomas Wilke and published by Springer Science & Business Media. This book was released on 2009-04-02 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ancient lakes are exceptional freshwater environments that have continued to exist for hundreds of thousands of years. They have long been recognized as centres of biodiversity and hotspots of evolution. During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology. The contributions in this volume deal with patterns and processes of biological diversification in three prominent ancient lake systems. Of these, the famous East African Great Lakes already have a strong tradition of evolutionary studies, but the two other systems have so far received much less attention. The exceptional biodiversity of the European sister lakes Ohrid and Prespa of the Balkans has long been known, but has largely been neglected in the international literature until recently. The rich biota and problems of its evolution in the two central lake systems on the Indonesian island of Sulawesi, in turn, have only lately started to draw scientific attention. This volume aims at deepening the awareness of the unusual biological diversity in ancient lakes in general, and of the role of these lakes as natural laboratories for the study of speciation and diversification in particular. It should stimulate further research that will lead to a better understanding of key evolutionary processes in these lakes, and to knowledge that might help in mitigating the deterioration of their diversity in the future.
