Download or read book Manual of Forensic Taphonomy written by James T. Pokines and published by CRC Press. This book was released on 2021-12-22 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goals in any forensic skeletal analysis are to answer who is the person represented (individualization), how that person died (trauma/pathology) and when that person died (the postmortem interval or PMI). The analyses necessary to generate the biological profile include the determination of human, nonhuman or nonosseous origin, the minimum number of individuals represented, age at death, sex, stature, ancestry, perimortem trauma, antemortem trauma, osseous pathology, odontology, and taphonomic effects—the postmortem modifications to a set of remains. The Manual of Forensic Taphonomy, Second Edition covers fundamental principles of these postmortem changes encountered during case analysis. Taphonomic processes can be highly destructive and subtract information from bones regarding their utility in determining other aspects of the biological profile, but they also can add information regarding the entire postmortem history of the remains and the relative timing of these effects. The taphonomic analyses outlined provide guidance on how to separate natural agencies from human-caused trauma. These analyses are also performed in conjunction with the field processing of recovery scenes and the interpretation of the site formation and their postdepositional history. The individual chapters categorize these alterations to skeletal remains, illustrate and explain their significance, and demonstrate differential diagnosis among them. Such observations may then be combined into higher-order patterns to aid forensic investigators in determining what happened to those remains in the interval from death to analysis, including the environment(s) in which the remains were deposited, including buried, terrestrial surface, marine, freshwater, or cultural contexts. Features Provides nearly 300 full-color illustrations of both common and rare taphonomic effects to bones, derived from actual forensic cases. • Presents new research including experimentation on recovery rates during surface search, timing of marine alterations, trophy skulls, taphonomic laboratory and field methods, laws regarding the relative timing of taphonomic effects, reptile taphonomy, human decomposition, and microscopic alterations by invertebrates to bones. • Explains and illustrates common taphonomic effects and clarifies standard terminology for uniformity and usage within in the field. While the book is primarily focused upon large vertebrate and specifically human skeletal remains, it effectively synthesizes data from human, ethological, geological/paleontological, paleoanthropological, archaeological artifactual, and zooarchaeological studies. Since these taphonomic processes affect other vertebrates in similar manners, The Manual of Forensic Taphonomy, Second Edition will be invaluable to a broad set of forensic and investigative disciplines.
Download or read book Herring and People of the North Pacific written by Thomas F. Thornton and published by University of Washington Press. This book was released on 2021-01-31 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herring are vital to the productivity and health of marine systems, and socio-ecologically Pacific herring (Clupea pallasii) is one of the most important fish species in the Northern Hemisphere. Human dependence on herring has evolved for millennia through interactions with key spawning areas—but humans have also significantly impacted the species’ distribution and abundance. Combining ethnological, historical, archaeological, and political perspectives with comparative reference to other North Pacific cultures, Herring and People of the North Pacific traces fishery development in Southeast Alaska from precontact Indigenous relationships with herring to postcontact focus on herring products. Revealing new findings about current herring stocks as well as the fish’s significance to the conservation of intraspecies biodiversity, the book explores the role of traditional local knowledge, in combination with archeological, historical, and biological data, in both understanding marine ecology and restoring herring to their former abundance.
Download or read book The Archaeology of North Pacific Fisheries written by Madonna L. Moss and published by University of Alaska Press. This book was released on 2011-11-15 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: For thousands of years, fisheries were crucial to the sustenance of the First Peoples of the Pacific Coast. Yet human impact has left us with a woefully incomplete understanding of their histories prior to the industrial era. Covering Alaska, British Columbia, and Puget Sound, The Archaeology of North Pacific Fisheries illustrates how the archaeological record reveals new information about ancient ways of life and the histories of key species. Individual chapters cover salmon, as well as a number of lesser-known species abundant in archaeological sites, including pacific cod, herring, rockfish, eulachon, and hake. In turn, this ecological history informs suggestions for sustainable fishing in today’s rapidly changing environment.

Download or read book Overview of mitigation measures to reduce the incidental catch of vulnerable species in fisheries written by Sacchi, J. and published by Food & Agriculture Org.. This book was released on 2021-06-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potentially harmful contact between fisheries and marine vulnerable species represents a global conservation issue and efforts to mitigate the negative repercussions of these interactions belong in strategies for ensuring the sustainability of fisheries. This literature review offers a survey of mitigation measures and techniques that have been developed and tested around the world, aiming to address both the incidental catch of highly mobile species – specifically, cetaceans, seabirds, sharks and rays, and sea turtles – and depredation caused by dolphins. Based on research detailed in over 300 documents, including peer-reviewed publications, reports from international organizations and papers available on the internet, most of the mitigation techniques illustrated are still under development, with only a few already adopted through legislation. The selected mitigation measures are grouped by main types of fishing gear – gillnets and trammel nets, longlines and lines, trawls, purse seines, traps and pots – and further subdivided according to which of the four main groups of vulnerable species – cetaceans, seabirds, sharks and rays, or sea turtles – they are designed to protect. Preventive and curative approaches covering both technical measures (gear modifications, strategies, as well as acoustic, visual, magnetic and chemosensory deterrents) and management measures are described.

Download or read book Time and Complexity in Historical Ecology written by William Balée and published by Columbia University Press. This book was released on 2006-06-22 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of studies by anthropologists, botanists, ecologists, and biologists is an important contribution to the emerging field of historical ecology. The book combines cutting-edge research with new perspectives to emphasize the close relationship between humans and their natural environment. Contributors examine how alterations in the natural world mirror human cultures, societies, and languages. Treating the landscape like a text, these researchers decipher patterns and meaning in the Ecuadorian Andes, Amazonia, the desert coast of Peru, and other regions in the neotropics. They show how local peoples have changed the landscape over time to fit their needs by managing and modifying species diversity, enhancing landscape heterogeneity, and controlling ecological disturbance. In turn, the environment itself becomes a form of architecture rich with historical and archaeological significance. Time and Complexity in Historical Ecology explores thousands of years of ecological history while also addressing important contemporary issues, such as biodiversity and genetic variation and change. Engagingly written and expertly researched, this book introduces and exemplifies a unique method for better understanding the link between humans and the biosphere.
