Taking a new global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective. Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l. and Eurasian plates over the last 600 Ma of Earth's history. The geological record starts with the amalgamation of Gondwana in the Neoproterozoic succeeded by the rifting and spreading of the Rheic ocean; its demise, which led to the amalgamation of Pangea in the late Paleozoic; the rifting and spreading of several arms of the Neotethys ocean in the Mesozoic Era and their ongo...
Polycystine radiolaria are exclusively marine protists and are found in all ocean waters, from polar regions to the tropics, and at all water depths. There are approximately 600 distinct described living species and several thousand fossil species of polycystines. Radiolarians in general, and polycystines in particular, have recently been shown to be a major component of the living plankton and important to the oceanic carbon cycle. As fossils radiolarians are also fairly common, and often occur in sediments where other types of fossils are absent. This has made them very valuable for certain types of geologic research, particularly estimating the geologic age of the sediments containing the...
Radiolaria are a very diverse marine siliceous microplankton group that have existed at least snice the Cambrian to the recent. This volume gives a representative view of research topics discussed at the 10th International Meeting of Radiolarian Palaeontologists. The articles of this volume cover mainly radiolarian biochronology and radiolarian fauna changes.
De Wever's ode to the invisible world around us allows readers to peer directly into a minute microcosm with massive implications, even traversing eons to show us how life arose on Earth.
This book is the first of its kind, providing in-depth analysis of the retrograde evolution occurring during major extinction periods. The text offers a non-strictly adaptative explanation of repetition of phyla after the major extinctions, utilizing a study of seven phylogenetically distinct groups. This opens a new experimental field in evolutionary biology with the possibility of reconstructing ancestral forms in lab by applying artificial stresses.
This comprehensive review of Mexican regulatory policy outlines progress made by Mexico since the 1999 review conducted by the OECD, and makes recommendations for further reforms aimed at promoting investment and boosting productivity and ...
The World Bank's research is intended to address critical issues and problems facing member governments in developing and transition economies. How can the governments of the poorest countries generate enough revenue to provide the education and health services essential to reducing poverty and promoting growth and development? How can poor countries attract investors to build the infrastructure their economies need? How can they develop systems to bring clean water to the 2 billion people without it today? How can they train teachers and bring to class the 115 million children who have not yet received any education? And how can rich countries be persuaded to lower market barriers, helping ...
