This book was released on 1977 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homogeneous Thalassia beds in back-reef flat (less than 1 m) and Discovery Bay (about 3 m) were sampled for 12 successive months in Jamaica, West Indies. Living foraminifera were enumerated in each of four monthly replicates consisting of 20 ml of sediment. At the sampling times, water temperature, sediment temperature, salinity, oxygen saturation, water pH, sediment pH, sediment median, sediment sorting, turbidity, particulate organic carbon, Thalassia weight, and weight percent silt plus clay were measured. In all, 18,644 individuals belonging to 143 species were picked, sorted, and identified. The back-reef flat habitat contained 7,745 individuals belonging to 115 species, while the Discovery Bay contained 10,899 individuals belonging to 117 species. Fisher's log-series fits the distribution of species abundances at both habitats well. The number of species, information function, and equitability are usually greater at Discovery Bay for individual 20 ml samples. A general linear model consisting of parameters for station differences, overall periodicity, interaction of station differences and overall periodicity, and environmental variables was constructed. The densities of the 19 most abundant species were statistically analyzed individually (univariate) and simultaneously (multivariate). Univariate analyses indicate six species have significant station differences (95% level) and seven exhibit periodicity. The environmental variables are not significant for any of the species. Multivariate analyses indicate a significant difference between stations and an overall periodicity. As in the univariate analyses, environmental variables are not significant. The results suggest that in tropical habitats changes in species densities are regulated biotically. The new species Ammonia jacksoni, Elphidium norvangi, Fissurina goreaui, Discorbinella minuta, Glabratella altispira and G. compressa are described. Taxonomic remarks are presented for most of the species.

Download or read book Microdistribution of Foraminifera in a Single Bed of the Monterey Formation Monterey County California written by Roberta K. Smith and published by . This book was released on 1986 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: While several papers exist on the small scale spatial distribution of living foraminifera, almost no work exists on the small scale spatial distribution of fossils. The present study took 24 (5 ml) replicates 10 cm apart along one bed of the Monterey Formation in California.The mean density for all replicates is 6084.96 with a standard deviation of 8776.95. Both inspection and a cluster analysis of the data indicate replicates 20-24 have a much higher density and different rank order of abundance than replicates 1-19. The mean density for the total of all species in replicates 1-19 is 2387.47 with a standard deviation of 1175.58. For replicates 20-24 the mean density is 20135.40 with a standard deviation of 11181.40. The spatial variability is so great that four replicates (more than commonly taken) would only allow us to be 95% confident that we are within 50% of the true mean. Because age determination is based on presence of particular taxa rather than on densities, stratigraphic assignment would still be possible.The three species dominating the 1-19 group make up from 86% to 99% of the fauna. The three species dominating the 20-24 group make up from 77% to 85% of the fauna. Two of these are also dominant in the 1-19 group, but the most dominant species in the 20-24 group constitutes only

Download or read book Oceanography and Marine Biology An Annual Review Volume 60 written by S. J. Hawkins and published by CRC Press. This book was released on 2022-12-08 with total page 1027 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanography and Marine Biology: An Annual Review remains one of the most cited sources in marine science and oceanography. The ever-increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative refereed reviews summarizing and synthesizing the results of both historical and recent research. This Volume celebrates 60 years of OMBAR, over which time it has been an essential reference for research workers and students in all fields of marine science. The peer-reviewed contributions in Volume 60 are available to read Open Access via this webpage and on OAPEN. If you are interested in submitting a review for consideration for publication in OMBAR, please email the Editor-in-Chief, Stephen Hawkins ([email protected]) for Volume 61. For Volume 62 onwards, please email the new co-Editors in Chief, Dr Peter Todd ([email protected]) and Dr Bayden Russell ([email protected]). Volume 60 features an editorial on the UN Decade of Ocean Science and goes on to consider such diverse topics as Cenozoic tropical marine biodiversity, blue carbon ecosystems in Sri Lanka, marine litter and microplastics in the Western Indian Ocean, and the ecology and conservation status of the family Syngnathidae in southern and western Africa. This volume also contains a retrospective Prologue on the evolution of OMBAR and pays tribute to one of its early Editors in Chief, Margaret Barnes, by providing an update on her review in OMBAR of the stalked barnacle Pollicipes. Supplementary online videos as well as additional Tables and Appendices are available on the Support Tab of the book's Routledge webpage. An international Editorial Board ensures global relevance and expert peer review, with editors from Australia, Canada, Hong Kong, Ireland, Singapore and the UK. The series volumes find a place in the libraries of not only marine laboratories and oceanographic institutes, but also universities worldwide.

This book was released on 2000 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 13 papers in this collection examine the coastal regions, the Gulf of Maine, and the continental shelf off of Atlantic Canada in context with new radiocarbon age analyses, providing a detailed history of climate changes, marine transgression, emergence, and relative sea- level history. Specific topics include deglaciation of the Gulf of Maine, Late Quaternary morphogenesis of a marine-limit delta plain in southwest Maine, morainal banks and the deglaciation of coastal Maine, and glacial dynamics, deglaciation, and marine invasion in southern Quebec. Material originated at a March 1998 symposium held in Maine at the 33rd Annual Meeting of the Northeastern Section of the Geological Society of America.

Book excerpt: Estuarine Interactions is a compilation of papers presented at the Fourth International Estuarine Research Federation Conference, held at the Mount Airy Lodge, Mount Pocono, Pennsylvania in October 1977. The compendium consists of scientific investigations on the structure and functioning of estuaries and adjacent environments. This volume includes the written form of the invited papers that were part of eight sessions. Papers presented deal with topics on estuarine management needs, impacts of coastal engineered systems, and productivity and initial photosynthate dispersion in the ecosystem. Natural catastrophic events in the estuarine environment, the impact of possible climatic changes on estuarine ecosystems, and pollutant cycling and water quality are likewise discussed. Estuarine scientists will find the book invaluable.
