High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.

The over-all aim of the book is to collect and add to the information published already on the larger benthic foraminifera and in cases their associated algae. Many decades of research in the Far East, to some extent in the Middle East and Americas has lead to numerous articles with confused systematics. Therefore, with the aid of new and precise age dates, from calcareous nannofossils and Sr isotopes, the current schemes of the larger foraminifera in a relatively precise chronostratigraphic and sequence stratigraphic framework are revised. This is achieved by: 1) establishing the systematic and occurrences of larger foraminifera from carbonate rocks in successions covering the Carboniferous to Miocene, with careful taxonomic comparison with the known records in the different bioprovinces; 2) illustration fossils of different families and groups at generic levels. 3) illustrations of important species and comparing distributions of different taxa. The inventory of larger benthic foraminifera focuses on the main important groups and the illustration of their genera. Reviews of the global state of the art of each group are complemented with the new data, and the direct palaeobiogeographic relevance of the new data is analyzed. * A unique, comprehensive reference work on the larger foraminifera. * A documentation of the biostratigraphic ranges and palaeoecological significance of larger foraminifera which is essential for understanding many major oil-bearing sedimentary basins. *The palaeogeographic interpretations of the shallow marine late Palaeozoic to Cenozoic world.

This book provides a representative assessment of the state of the art of research on Paleogene rotaliid larger foraminifera. It gives an overview of the current understanding of systematics of this group and, in particular, of its biostratigraphic importance and palaeobiogeography. The senior author of the work, late Professor Hottinger, a leading scientist in the field, both from a systematic and applied side, presents in this book his most recent advances. The foraminiferal family Rotaliidae is a traditional group used frequently which plays an important role for petroleum exploration in the biostratigraphy and palaeobiogeography of Paleogene shallow water deposits in the Middle East. This book aims to introduce rotaliid representatives as index fossils that can be recognized in random thin-sections of cemented rocks. The book is generously illustrated with an unprecedented degree of accuracy. The selection of taxa is restricted to forms having lived in the Paleocene and the Eocene, where their biostratigraphic significance is much higher than during later epochs. However, some additional rotaliid taxa, from the Late Cretaceous or that do not belong to the family Rotaliidae sensu stricto, are included in this book in order to demonstrate particular roots of rotaliid phylogenetic lineages in the previous community maturation cycle or to delimit the taxon Rotaliidae with more precision. This book can be considered as a reference in the field.

Foraminiferal cultures now serve as tools for researching biological, environmental, and geological topics. However, the biological backgrounds, in particular the natural histories of foraminifera, largely remain unclear. It is also true that the different techniques used in different subdisciplines are a setback to fully understanding the subject. Taken together, these factors prevent progress in experimental approaches to foraminiferal studies. This book aims to share and exchange knowledge between researchers from different subdisciplines, and the book should interest not only foraminiferal researchers but also scientists who are working with marine organisms to explore questions in relation to biology, geology, and oceanography.

Symbiosis is the fourth volume in the series Cellular Origin and Life in Extreme Habitats (COLE). Fifty experts, from over a dozen countries, review their current studies on different approaches to these phenomena. The chapters present various aspects of symbiosis from gene transfer, morphological features, and biodiversity to individual organisms sharing mutual cellular habitats. The origin of the eukaryotic phase is discussed with emphasis on cyanelles, H syntrophy, N2 fixation, and S-based symbiosis (as well as the origin of mitochondrion, chloroplast, and nucleus). All members of the three domains of life are presented for sharing symbiotic associations. This volume brings the concept of living together as `One plus One (plus One) equals One.' The purpose of this book is to introduce the teacher, researcher, scholar, and student as well as the open-minded and science-oriented reader to the global importance of this association.

This study investigates, for the first time, the distribution and taxonomy of modern benthic foraminifera from the western Sunda Shelf, southern South China Sea. The uppermost centimeter of 54 surface sediment samples ([greater than] 150 [mu]m) from nearshore (8 m) to inner shelf (60 m) water depths yielded 125 species. Five sample groups (CGT1–5) are recognized by cluster analysis of the total (live + dead) foraminiferal relative abundance data. Discriminant analysis and ANOVA both revealed that the five groups are statistically distinguishable at the 95% confidence level. The distribution of groups is related to variations in depth (as a proxy for several environmental factors) and substrate grain-size. This relationship is confirmed by canonical correspondence analysis. CGT1, located closest to shore (8–14 m water depth), has a high diversity assemblage (49 species) and is characterized by Amphistegina radiata and Amphistegina lessonii. CGT1 occurs in medium to coarse quartz sand substrates likely derived from the nearby Terengganu River with the exception of a single station (TR1-S2). This site is characterized by a mud substrate, the taxa Ammobaculites exiguus, Millettiana millettii, Planorbulina acervalis, and Rosulina globularis, and an unusually high relative abundance (3%) of planktonic foraminifera. CGT2 (21–22 m) has a lower diversity assemblage (33 species) and is strongly dominated by A. radiata and A. lessonii, often with tests infilled by the authigenic mineral berthierine. CGT2 occurs in gravelly quartz sand substrates. CGT3 (32–41 m) occurs in shelly muddy quartz sand substrates, has a high diversity assemblage (46 species), and is characterized by Assilina ammonoides, Discorbinella bertheloti, and Asterorotalia milletti. Like CGT2, berthierine-rich internal molds of Amphistegina tests are common. CGT4 (44–59 m) occurs in mud substrates and is characterized by Heterolepa dutemplei and A. milletti; the nearshore taxa A. radiata and A. lessonii do not occur in this group. CGT4 has the highest diversity assemblage (51 species) of all the sample groups and foraminiferal tests are well preserved. CGT5, located furthest from shore at 60 m water depth and in shelly sandy mud, has a high diversity assemblage (46 species) and is characterized by H. dutemplei and A. ammonoides, with rare A. milletti; live (rose Bengal-stained) specimens are rare in CGT5 compared to the other four groups. Comparison to foraminiferal assemblages in underlying Pleistocene core material suggests this assemblage occurs in a lag deposit possibly associated with modern bottom current activity. Combining the results of this study with previously published research, three generalized foraminifera-based subdivisions are recognized across the Sunda Shelf (8–200 m water depth). Nearshore areas ([less than] 40 m) are dominated by fine to coarse sand substrates and symbiont-bearing taxa (A. lessonii and A. radiata). Inner shelf areas (40–100 m) are associated with sandy mud substrates and high relative abundances of H. dutemplei. Outer shelf areas (100–200 m) are associated with muddy substrates and the presence of Uvigerina schwageri. These data can be used as the basis for paleoenviromental reconstruction of Quaternary core material from the Sunda Shelf.

One of the leading textbooks in its field, Bringing Fossils to Life applies paleobiological principles to the fossil record while detailing the evolutionary history of major plant and animal phyla. It incorporates current research from biology, ecology, and population genetics, bridging the gap between purely theoretical paleobiological textbooks and those that describe only invertebrate paleobiology and that emphasize cataloguing live organisms instead of dead objects. For this third edition Donald R. Prothero has revised the art and research throughout, expanding the coverage of invertebrates and adding a discussion of new methodologies and a chapter on the origin and early evolution of life.

Most of our information about the evolution of Earths oceanclimate system comes from the analysis of sediments laid down in the past. For example, the microfossil assemblage reflects the temperature, salinity and nutrient abundance of the water in which the organisms lived, while the chemical and isotopic composition of biogenic carbonates may be used to reconstruct past variations in the operation of the carbon cycle, as well as changes in ocean circulation. Nevertheless, understanding the link between these sediment variables (or proxies) and environmental conditions is not straightforward. This volume adopts a novel approach by bringing together palaeontologists, geochemists and palaeoceanographers, who contribute evidence that is required to better constrain these proxies. Topics include: (i) processes of biomineralization, and their effect on the chemical and isotopic composition of different organisms; (ii) proxy validation, including field, laboratory and theoretical studies; (iii) the links between modern and fossil organisms.

Written expressly for undergraduate and graduate geologists, this book focuses on how geochemical principles can be used to solve practical problems. The attention to problem-solving reflects the authors'belief that showing how theory is useful in solving real-life problems is vital for learning. The book gives students a thorough grasp of the basic principles of the subject, balancing the traditional equilibrium perspective and the kinetic viewpoint. The first half of the book considers processes in which temperature and pressure are nearly constant. After introductions to the laws of thermodynamics, to fundamental equations for flow and diffusion, and to solution chemistry, these principles are used to investigate diagenesis, weathering, and natural waters. The second half of the book applies thermodynamics and kinetics to systems undergoing changes in temperature and pressure during magmatism and metamorphism. This revised edition incorporates new geochemical discoveries as examples of processes and pathways, with new chapters on mineral structure and bonding and on organic matter and biomarkers. Each chapter has worked problems, and the authors assume that the student has had a year of college-level chemistry and a year of calculus. Praise for the first edition "A truly modern geochemistry book.... Very well written and quite enjoyable to read.... An excellent basic text for graduate level instruction in geochemistry." —Journal of Geological Education "An up-to-date, broadly conceived introduction to geochemistry.... Given the recent flowering of geochemistry as an interdisciplinary science, and given the extent to which it now draws upon the fundamentals of thermodynamics and kinetics to understand earth and planetary processes, this timely and rigorous [book] is welcome indeed." —Geochimica et Cosmochimica Acta

Foraminifera are free-living protozoa that grow an elaborate, solid calcite skeleton. Their well-marked evolutionary record makes them of outstanding value in zonal stratigraphy. The role of fossil planktonic foraminifera as markers for biostratigraphical zonation and correlation underpins most drilling of marine sedimentary sequences and is key to hydrocarbon exploration. Biostratigraphic and Geological Significance of Planktonic Foraminifera presents a comprehensive analysis of existing data on fossil planktonic foraminifera genera and their phylogenetic evolution in time and space. In addition, the book contains new, unpublished data on carbonate thin sections with identified fossil planktonic foraminifera from the Far East to offshore Brazil and South Africa. The first book to synthesize the biostratigraphic and geological usefulness of planktonic foraminifera Includes a discussion of the recent advances being enabled by molecular studies of living forms Opens a new field of dating planktonic foraminifera in carbonates and expands their usefulness in hydrocarbon exploration

This book consists of a collection of ten articles covering a variety of modern research topics in foraminiferal classification, stratigraphic distribution, ecology, paleoceanography and evolution. Significant contributions include road-opening studies in the evolutionary occurrence of the group in the Early Jurassic and evolutionary classification of the Cretaceous heterohelicid, planomalinid and globotruncanid planktics. Two general descriptions of the benthic foraminiferal assemblages from the Late Jurassic of Canada and modern sediments of the central Mediterranean Sea further add to the conceptual high density of the volume. A distinct advance in the biostratigraphy of the benthic foraminifera is the definition of the concept of biosequence, which is crucial for a better integration of the foraminiferal changes in time and space with the sequence stratigraphy concepts. Ecology and oceanography studies in both modern and ancient settings focus, among others, on the changes at the Cretaceous/Cenozoic boundary in the Tethyan Region and modern anoxia influences on the foraminiferal communities of the Black Sea. The variety of new and well-documented ideas, data and interpretations complement and at the same time challenge the already existing ones. Overall, the volume is of potential high interest for the foraminiferologists involved in both fundamental and applied inland and offshore studies.
