Download or read book Ontogeny Intraspecific Variation and Systematics of the Late Cambrian Trilobite Dikelocephalus written by Nigel C. Hughes and published by . This book was released on 1994 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biometric analyses of well-localized specimens of the trilobite Dikelocephalus from the St. Lawrence Formation (Upper Cambrian), northern Mississippi Valley, suggest that all specimens belong to a single, highly variable morphospecies, D. minnesotensis. A complex pattern of ontogenetically-related and ontogeny-independent variation produced a mosaic of morphotypes, which show greater diversity than previously recorded within trilobite species. There is considerable variation within collections made from single beds. Variations of characters among collections are mosaic, and are clinal in some cases. Patterns of variation within Dikelocephalus cannot be related to lithofacies occurrence. There are no obvious temporal variations in D. minnesotensis within the St. Lawrence Formation, but some Dikelocephalus from the underlying Tunnel City Group may belong to a different taxon. The validity of this early taxon is questionable due to a lack of available material. The mosaic pattern of variation in Dikelocephalus mimics that documented at higher taxonomic levels in primitive libristomate trilobites, and helps explain difficulties in providing a workable taxonomy of primitive trilobites. Results caution proposition of evolutionary scenarios that do not take account of intraspecific variation. The recovery of dorsal shields of Dikelocephalus permits the first detailed reconstruction of the entire exoskeleton. The systematics of the genus is revised and twenty-five species are suppressed as junior synonyms of D. minnesotensis.

Download or read book Dasycladales written by Sigrid Berger and published by Oxford University Press, USA. This book was released on 1992 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first monograph atlas on Dasycladales to extensively describe the unique morphologic features of both fossil and living species, following the phylogeny of these single cell organisms through their more than 500 million years of existence. Due to the increasingly detailed knowledge on the evolution of morphologic characteristics, it is now possible to determine the time of development of the living genera, and their distribution is specified in accompanying maps. For the first time, the systematic classification of the living Dasycladales makes use of their availability in laboratory cultures. Crosses were performed between questionable species and morphologic characteristics observed over several generations excluding environmental influences on their expression. A unique collection of photographs and scanning electron micrographs documents the features of the living Dasycladales and will be of great value for researchers and students as well as easily understandable for interested observers. Schematic drawings and photographs describe the life cycle. The depicted peculiarities of the living Dasycladales, the knowledge presented on the establishment of laboratory cultures, on important techniques for cell biological research, as well as on their role in cell biology could stimulate researchers and students to "rediscover" these living fossils.

Download or read book Bibliography and Index of the Sirenia and Desmostylia written by Daryl P. Domning and published by . This book was released on 1996 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significant published literature on the neobiology, paleobiology, and ethnobiology of the mammalian orders Sirenia and Desmostylia is exhaustively cataloged in approximately 4590 main entries alphabetized by the author. Both technical and popular works are included, and many entries are annotated. The earliest work cited is a letter by N. Syllacio published in 1494 or 1495, describing Columbus's second voyage to the New World. The effective closing date of the bibliography was 1 May 1994. Six appendices list serial publications devoted to Sirenia, additional sources for history of sirenology and sirenian conservation, coins and postage stamps depicting sirenians, a comprehensive classification and synonymy of sirenians and desmostylians, a summary of the nomenclature of the Recent species of sirenians, and an alphabetical list of the species-group names that have been applied to sirenians and desmostylians. An extensive index is provided, employing 1059 subject headings and cross references; the subject headings include all Linnaean names and combinations ever employed for sirenians and desmostylians, as well as names of all reported sirenian food plants and parasites. More than 40% of the main entries are fully indexed, and many others are partially indexed, yielding a total of over 13,950 index entries. Each complete index entry includes author and date of the work cited, a brief annotation describing the content of the work as it pertains to the indexed subject, and a page reference for the material pertaining to that subject.

Download or read book Geographical Information Systems in Archaeology written by James Conolly and published by Cambridge University Press. This book was released on 2006-05-04 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographical Information Systems has moved from the domain of the computer specialist into the wider archaeological community, providing it with an exciting new research method. This clearly written but rigorous book provides a comprehensive guide to that use. Topics covered include: the theoretical context and the basics of GIS; data acquisition including database design; interpolation of elevation models; exploratory data analysis including spatial queries; statistical spatial analysis; map algebra; spatial operations including the calculation of slope and aspect, filtering and erosion modeling; methods for analysing regions; visibility analysis; network analysis including hydrological modeling; the production of high quality output for paper and electronic publication; and the use and production of metadata. Offering an extensive range of archaeological examples, it is an invaluable source of practical information for all archaeologists, whether engaged in cultural resource management or academic research. This is essential reading for both the novice and the advanced user.
