What do we know about Mediterranean Cold (Deep)-Water coral ecosystems? In this book, specialists offer answers and insights with a series of chapters and short papers about the paleoecology, biology, physiology and ecology of the corals and other organisms that comprise these ecosystems. Structured on a temporal axis—Past, Present and Future—the reviews and selected study cases cover the cold and deep coral habitats known to date in the Mediterranean Basin. This book illustrates and explains the deep Mediterranean coral habitats that might have originated similar thriving ecosystems in today’s Atlantic Ocean.

An up-to-date atlas of an important fossil and living group, with the Natural History Museum. Deep-sea benthic foraminifera have played a central role in biostratigraphic, paleoecological, and paleoceanographical research for over a century. These single–celled marine protists are important because of their geographic ubiquity, distinction morphologies and rapid evolutionary rates, their abundance and diversity deep–sea sediments, and because of their utility as indicators of environmental conditions both at and below the sediment–water interface. In addition, stable isotopic data obtained from deep–sea benthic foraminiferal tests provide paleoceanographers with environmental information that is proving to be of major significance in studies of global climatic change. This work collects together, for the first time, new morphological descriptions, taxonomic placements, stratigraphic occurrence data, geographical distribution summaries, and palaeoecological information, along with state-of-the-art colour photomicrographs (most taken in reflected light, just as you would see them using light microscopy), of 300 common deep-sea benthic foraminifera species spanning the interval from Jurassic - Recent. This volume is intended as a reference and research resource for post-graduate students in micropalaeontology, geological professionals (stratigraphers, paleontologists, paleoecologists, palaeoceanographers), taxonomists, and evolutionary (paleo)biologists.

Evolution and Geological Significance of Larger Benthic Foraminifera is a unique, comprehensive reference work on the larger benthic foraminifera. This second edition is substantially revised, including extensive re-analysis of the most recent work on Cenozoic forms. It provides documentation of the biostratigraphic ranges and palaeoecological significance of the larger foraminifera, which is essential for understanding many major oil-bearing sedimentary basins. In addition, it offers a palaeogeographic interpretation of the shallow marine late Palaeozoic to Cenozoic world. Marcelle K. BouDagher-Fadel collects and significantly adds to the information already published on the larger benthic foraminifera. New research in the Far East, the Middle East, South Africa, Tibet and Americas has provided fresh insights into the evolution and palaeographic significance of these vital reef-forming forms. With the aid of new and precise biostratigraphic dating, she presents revised phylogenies and ranges of the larger foraminifera. The book is illustrated throughout, with examples of different families and groups at the generic levels. Key species are discussed and their biostratigraphic ranges are depicted in comparative charts, which can be found at http://discovery.ucl.ac.uk/10047587/2/Charts.pdf.

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.

Cold-water corals occur worldwide from high latitudes to tropical areas, in various settings from the deep-sea to shallow marine environments near the coast. The topic of this thesis is the establishment and extension of knowledge about environmental conditions controlling cold-water coral (CWC) mound development. From literature it is known that glacial-interglacial cycles drive development and geographic distribution of CWC mounds on a large scale. On the other hand, knowledge about the influence of small scale climatic and oceanographic changes during the Holocene is scarce. Thus, this thesis focuses on the investigation of the limited Holocene climatic and oceanographic changes and their effect on the process of mound genesis. For this purpose, a Holocene CWC mound setting in a sound in the Altafjord in northern Norway (70°N) -- the Stjernsund -- was chosen and the local benthic ecosystem was extensively analysed. Von den sub-arktischen hohen Breiten bis in warme tropische Zonen besiedeln Kaltwasserkorallen unseren Planeten. Sie haben sich verschiedenste Lebensräume erschlossen --- Von der Tiefsee bis zu marinen Flachwassergebieten an der Küste kann ihr Vorkommen beobachtet werden. Sie bilden faszinierende Ökosysteme die erst in den letzten Jahrzehnten intensiver erforscht wurden. Diese Arbeit widmet sich der tieferen Erforschung dieser Lebensräume. Im Fokus stehen dabei Umweltbedingungen, die die Entwicklung der Kaltwasserkorallenvorkommen kontrollieren. Umfangreiche frühere Untersuchungen haben bereits gezeigt, dass ihr Wachstum, als auch ihre geographische Verbreitung im Wesentlichen von Glazial-Interglazial-Zyklen gesteuert werden. Die kurzzeitlichen klimatischen und ozeanographischen Steuerungsfaktoren sind im Vergleich dazu jedoch nahezu unbekannt. Daher konzentriert sich diese Arbeit auf die Erforschung von kurzeitigen klimatischen und ozeanographischen Veränderungen, die insbesondere im Holozän zu beobachten sind, sowie deren mögliche Auswirkungen auf die Entwicklung von Kaltwasserkorallen Mounds. Hierzu wurde der holozäne Kaltwasserkorallen Mound im Stjernsund, ein Sund im Altafjord in Nordnorwegen (70°N) ausgewählt und dessen benthisches Ökosystem umfassend analysiert.

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
