Available in PDF, EPUB and Kindle. Book excerpt: MOCNESS plankton tows, sediment traps and sedimentary material are used to determine the linkage between bio-physical forcing and foraminiferal response over a range of time scales from the event scale to the glacial interglacial cycle. The annually averaged planktic foraminiferal fauna of the modem California Current is a diverse community composed of individuals from subarctic, transitional, and subtropical foraminiferal assemblages. This community is more diverse, but less abundant in total standing stock and shell flux than the subarctic community of the Gulf of Alaska. The use of plankton tow and isotopic data allow us to partition the foraminiferal community into shallow dwelling euphotic zone species and deep dwelling sub-thermocline species. On both the event and seasonal time scales, heterotrophic species were most abundant in cold, biomass rich coastal waters. In contrast, species which harbored endosymbionts were more abundant in oligotrophic waters with higher ambient light levels. During the Last Glacial Maximum (LGM), the diverse modern fauna was replaced with a low diversity, high flux, heterotrophic community similar to that of the modern Gulf of Alaska. Modern analog temperature estimates suggest the California Current was roughly 3°C cooler during the LGM than today. Coupled with oxygen isotopic results from G. bulloides, the surface thermal structure implies an equatorward flowing glacial California Current at these sites. The Polar Front thus remained north of these locations during the LGM. Comparison of glacial G. bulloides carbon isotopes and shell accumulation rates with organic carbon flux estimates implies the glacial California Current was (1) higher in nutrient content, (2) lower in plankton biomass, and (3) lower in export carbon flux than its modem counterpart. This description suggests that during the LGM the plankton community of the California Current was very similar to the modern plankton community of the Gulf of Alaska.

Download or read book Planktic Foraminifers in the Modern Ocean written by Ralf Schiebel and published by Springer. This book was released on 2017-02-17 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the taxonomy, biology, sedimentation, and carbonate geochemistry of modern species. Students, early career and advanced scientists alike will profit from a broad synthesis of the current understanding of planktic foraminifers as an ecological indicator, biogeochemical factories, and proxies in paleoceanography. The classification of modern species is amply illustrated with electron and light microscope images of morphotypes, addresses the state-of-the-art of molecular genetics of species, and provides a detailed guide for any laboratory analyses. The biology of planktic foraminifers is extensively discussed in chapters dedicated to the cellular ultrastructure, nutrition, symbionts, reproduction, ontogeny, and test architecture. Building on the biological prerequisites, the distribution of planktic foraminifers is discussed at regional to global scale. The geochemistry and sedimentation of tests are considered in relation to the ecology of the living animal. In the final chapter, which examines the most common methods in planktic foraminifer research, hands-on information is provided on sampling, processing and analyzing samples in the laboratory, as well as selected established methods for data interpretation. The various topics discussed in this book are aimed at the application of planktic foraminifers as sensitive indicators of the changing climate and marine environment.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

Available in PDF, EPUB and Kindle. Book excerpt: In a single volume, the authors bring together a review of current biological understanding of planktonic foraminifera and apply it to developments in sedimentology. With the growing interest in the shells of this class of protozoa as indicators of the history of the earth, revealed through the sedimentary record, a comprehensive analysis of the biology of contemporary foraminifera has become necessary. Main topics covered include Taxonomy, Collecting and Culture Methods, Cellular Ultrastructure, Host and Symbiont Relationships, Trophic Activity and Nutrition, Reproduction, Shell Ontogeny and Architecture, Ecology and Sedimentation and Settlement of Shells.

Available in PDF, EPUB and Kindle. Book excerpt: This book envisages a multi-proxy approach using stable isotopes, geochemical proxies, magnetic susceptibility and associated biotic events for paleoclimatic and paleoenvironmental interpretations of the Mesozoic sedimentary record of India. Mesozoic rocks of India record abnormal sea level rise, greenhouse climate, intensified volcanism, hypoxia in seawater, extensive black shale deposition, and hydrocarbon occurrence. The Mesozoic has also witnessed mass extinction events, evolution of dinosaurs, and breakdown of the supercontinent Pangea and the formation of Gondwana. Although the Mesozoic geology of India has witnessed significant progress in the last century, literature survey reveals a huge gap in knowledge regarding sequence stratigraphy, chemostratigraphy and key geological events. A synthesis of sedimentological, paleontological and chemical data is included to presenting a comprehensive understanding of the Indian Mesozoic record to students, researchers and professionals.
