Download or read book The Pleistocene Old World written by Olga Soffer and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regional approaches to past human adaptations have generated much new knowledge and understanding. Researchers working on problems of adaptations in the Holocene, from those of simple hunter-gatherers to those of complex sociopolitical entities like the state, have found this approach suitable for comprehension of both ecological and social aspects of human behavior. This research focus has, however, until recently left virtually un touched a major spatial and temporaI segment of prehistory-the Old World during the Pleistocene. Extant literature on this period, by and large, presents either detailed site speeific accounts or offers continental or even global syntheses that tend to compile site speeific information but do not integrate it into whole c~nstructs of funetioning so ciocuhural entities. This volume presents our current state of knowledge about a variety of regional adaptations that charaeterized prehistoric groups in the Old World before 10,000 B. P. The authors of the chapters consider the behavior of humans rather than that of objects or features and present data and models for variaus aspects of past cultures and for culture change. These presentations integrate findings and understandings derived from a number of related disciplines actively involved in researching the past. Data and interpretations are offered on a range of Old \yorld regions during the PaIeolithic, induding Africa, Asia, Australia, and Europe, and chronological coverage spans from the Early to Late PIeisto cene.
Download or read book The Bluefin Tuna Fishery in the Bay of Biscay written by José Luis Cort and published by Springer. This book was released on 2019-02-07 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is an original contribution to the knowledge on fishing and research associated with one of the most enigmatic fish of our seas: bluefin tuna, Thunnus thynnus (L.). Based on available evidence, it reconstructs the possible methods used to catch large spawners in the Strait of Gibraltar thousands of years ago and describes the much more recent overfishing that led to a great reduction in the catches of the trap fishery on the area and the disappearance of the northern European fisheries. It is the first book to relate the overfishing of juvenile fishes in certain areas to the decline of large spawners in other very distant areas, revealing one of the main underlying causes of this decline, which has remained a mystery to the fishing sector and scientists alike for over 50 years. This finding should serve to prevent similar cases from arising in the future.
Download or read book PFASs in the Nordic environment written by Anna Kärrman and published by Nordic Council of Ministers. This book was released on 2019-03-15 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a screening study of in all ninety-nine conventional and emerging per- and polyfluoroalkyl substances (PFASs) in the Nordic environment. In addition, extractable organic fluorine (EOF) was analysed. The latter can provide the amount, but not identity, of organofluorine in the samples, which in turn can be used to assess the mass balance between known and unknown PFASs. The study was initiated by the Nordic Screening Group and funded by these and the Nordic Council of Ministers through the Chemicals Group.A total of 102 samples were analyzed in this study, including bird eggs, fish, marine mammals, terrestrial mammals, surface water, WWTP effluents and sludge, and air. Samples were collected by institutes from the participating countries and self-governing areas; Denmark, Faroe Islands, Finland, Greenland, Iceland, Norway, and Sweden.
Download or read book Stable Isotopes as Indicators of Ecological Change written by and published by Academic Press. This book was released on 2011-09-21 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 20th century has experienced environmental changes that appear to be unprecedented in their rate and magnitude during the Earth's history. For the first time, Stable Isotopes as Indicators of Ecological Change brings together a wide range of perspectives and data that speak directly to the issues of ecological change using stable isotope tracers. The information presented originates from a range of biological and geochemical sources and from research fields within biological, climatological and physical disciplines covering time-scales from days to centuries. Unlike any other reference, editors discuss where isotope data can detect, record, trace and help to interpret environmental change. - Provides researchers with groundbreaking data on how to predict the terrestrial ecosystems response to the ongoing rapid alterations - Reveals how ecosystems have responded to environmental and biotic fluctuations in the past - Includes examples from research by a wide range of biological and physical scientists who are using isotopic records to both detect and interpret environmental change
