Analytical Perspectives On A Protohistoric Cache Of Ceramic Jars From The Lower Colorado Desert, James M. Bayman, Richard H. Hevly, Boma Johnson, Karl J. Reinhard, Richard Ryan Jan 1996

Analytical Perspectives On A Protohistoric Cache Of Ceramic Jars From The Lower Colorado Desert, James M. Bayman, Richard H. Hevly, Boma Johnson, Karl J. Reinhard, Richard Ryan

Karl Reinhard Publications

A cache of hermetically sealed ceramic jars found in the Lower Colorado Desert was examined using chronometric dating, pollen and macrofossil extraction, design analysis, and water retention experimentation. The cache apparently dates to the protohistoricfifteenth through seventeenth centuries. Findings from these studies contribute to knowledge in four problem areas: (1) ceramic jar function and use-history; (2) storage technology and caching behavior; (3) ceramic dating and chronology; and (4) symbolic iconography. Biotic remains from inside the jars document their use for transporting a variety of riverine and desert plants, before they were finally filled with flowers and seeds, and placed in …


Faunal Diversity Among Avian Parasite Assemblages: The Interaction Of History, Ecology, And Biogeography In Marine Systems, Eric P. Hoberg Jan 1996

Faunal Diversity Among Avian Parasite Assemblages: The Interaction Of History, Ecology, And Biogeography In Marine Systems, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Systematics and parasite biodiversity provide power and predictability in broad studies of history, ecology and biogeography in marine systems. Parasitic helminths are elegant markers of contemporary and historical ecological relationships, geographic distribution and host-phylogeny. Complex life cycles of helminths are strongly correlated with intricate food-webs. Dependence on a series of intermediate, paratenic, and definitive hosts indicates that each parasite species represents an array of organisms within a community and tracks broadly and predictably across many trophic levels. Host and geographic ranges of parasites are historically constrained by genealogical and ecological associations, and these determinents interact resulting in characteristic parasite community …


Microevolutionary Patterns And Molecular Markers: The Genetics Of Geographic Variation In Ascaris Suum, Steven A. Nadler Jan 1996

Microevolutionary Patterns And Molecular Markers: The Genetics Of Geographic Variation In Ascaris Suum, Steven A. Nadler

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Molecular markers have been used only rarely to characterize the population genetic structure of nematodes. Published studies have suggested that different taxa may show distinct genetic architectures. Isoenzyme and RAPD markers have been used to investigate geographic variation of Ascaris suum at the level of infrapopulations (nematodes within individual hosts), within localities, and among geographic regions. Independent estimates of genetic differentiation among population samples based on isoenzyme and RAPD data showed similar patterns and substantial correlation. Heterozygote deficiencies within infrapopulations and large values for inbreeding coefficients among infrapopulations suggested that the composition of these populations was not consistent with a …
