This volume presents the results of research on Arabian continental vertebrates discovered in the United Arab Emirates, the Sultanate of Oman, and the Republic of Yemen. The contributors provide information on Arabian palaeontology, stratigraphical, geological, isotropic and palaeomagnetic topics.
This report is based on fossil collections made over a vast area of the Canadian Arctic extending from Axel Heiberg Island in the north to the Aklavik region of the mainland and is a further contribution by the author on the Jurassic faunas of the Canadian Arctic. Detailed study of these ammonite faunas permits correlation of the associated Jurassic rocks and shows their faunal and stratigraphic relationships
with Alaska, East Greenland, and the Arctic areas of Europe and Asia.
Recent revisions to the early Paleozoic time scale have been used to recalibrate ages assigned to stratigraphically dated paleomagnetic poles of that era. In particular, a value of 545 Ma has been used for the base of the Cambrian. Selected poles have then been used to derive apparent polar.
This book could never have been written without the help, assistance, and
encouragement of many people. During the research phase, Professor Alex Kemp
and Dr. Richard Perren of the University of Aberdeen gave unstinting help and
advice, while Professor Roger Wootton of the City University was generous with
ideas and sources. Mr. John Westwood of Douglas–Westwood Associates kindly
read the draft.
In the last two decades, the discovery of signaling roles of ROS demonstrated their
universal use in biological systems. The third section of this book, entitled “Reactive
Species as Signaling Molecules” contains the chapters covering clear ROS-based signaling
in yeasts and plants. It is not strange that many authors provide readers with the
information gained from yeasts. This is a very popular classic eukaryotic model system to
disclose molecular mechanisms of cellular responses to oxidative stress (Lushchak, 2010).
In the first chapter of this book section, M. A.
A lot of unconformities and stratigraphic gaps have been discovered in the Paleozoic and Mesozoic stratigraphy of Bac Bo region (North Viet Nam), but their role in the regional geology was not accessed yet in detail. This paper is the first attempt to describe the most significant unconformities and stratigraphic gaps and discussing their role in regional geology.
The Upper Jurassic deposits of Milne Land lie in a key area for Jurassic Boreal
ammonite stratigraphy. Early collections brought back to Copenhagen by Rosenkrantz
(1929) and Aldinger (1935) were described in two classical monographs by
Spath (1935, 1936), and all these works continue to form the basis for subsequent
stratigraphical and palaeontological revisions. Since then extensive field work and
collecting have yielded important new material and much more detailed stratigraphical
information (Callomon, 1961; Hikansson et al., 1971; Birkelund et al.
