Disarticulation And Dissolution Of Crab Remains Across A Depth Gradient In The Bahamas: A Taphonomic Study, Rebecca A. Lincoln
Disarticulation And Dissolution Of Crab Remains Across A Depth Gradient In The Bahamas: A Taphonomic Study, Rebecca A. Lincoln
Honors Papers
The fields of Paleontology and Paleoecology would not be complete without taphonomy, the study of the processes affecting organisms between death and fossilization. Taphonomy is important because it allows us to make more complete conjectures about prehistoric organisms and environments, and makes us aware of possible holes and biases in the fossil record due to highly destructive processes or the loss of delicate, non-resistant organisms. Studies on the processes affecting modern organisms have contributed greatly to the understanding of ancient processes; however, most of these studies are nearshore and short-term. What is lacking is information on the effects of these …
Metametascience Towards Reconciliation, John P. Kennedy
Metametascience Towards Reconciliation, John P. Kennedy
Honors Papers
The ideal of consilience - the inductive concurrence of seemingly disparate ways of thinking into a single, unified, all-encompassing intellectual system - or more simply put, "unified learning" - has been largely set aside since the rise of the industrial age and the championing of the industrious, better-be it individualized mind of the enlightenment. The Catholic Church was the last western world-dominant institution to actively perpetuate and work according to the rubric of a unified field of knowledge. Our thoughts and everything else were under God and indivisible: our ethics and our physics alike were the immaterial idea-stuff of the …
Phylogenetic Inference And Neanderthal Mitochondrial Dna: Comparison Of Parsimony And Distance Models, Menahem Baguio Doura
Phylogenetic Inference And Neanderthal Mitochondrial Dna: Comparison Of Parsimony And Distance Models, Menahem Baguio Doura
Honors Papers
Recently, mtDNA was successfully extracted and sequenced from the Neanderthal type specimen (Krings et al, 1997, 1999). Researches attempted to determine the genetic relationship between the Neanderthal specimen and modem human populations using phylogenetic analysis and concluded that the variation existing between the Neanderthal specimen and the modem lineages falls outside the range of variation of modem human populations. Using molecular mutation rate assumptions, it has been concluded that the Neanderthal line diverged from the line leading to modem humans hundreds of thousands of years previous to earlier estimates. This suggests that Neanderthals went extinct without contributing genes to the …
Bad-Boy Bryozoan Biomarkers: Cheilostome Distribution Patterns Along A Bahamian Depth Gradient, Christopher J. Nytch
Bad-Boy Bryozoan Biomarkers: Cheilostome Distribution Patterns Along A Bahamian Depth Gradient, Christopher J. Nytch
Honors Papers
In 1993 and 1994, the Shelf and Slope Experimental Taphonomy Initiative (SSETI) deployed thirty-five samples of sea urchins along the continental shelf/slope of the Bahamas in an effort to explore the paleoecology and taphonomic potentials of shallow water carbonate environments. Samples were retrieved at 1-, 2-, and 6-year intervals for examination and comparison of epibiont accumulation. Tests and spines of the sea urchin Eucidaris were examined for encrusting cheilostome Bryozoa. Specimens were identified to the genus level. Assessment of abundance and distribution patterns with water depth shows that cheilostomes are prevalent in photic waters, and lacking at depth. Burial of …
As Sementes E O Conhecimento Que Elas Incorporam, Hugh Lacey
As Sementes E O Conhecimento Que Elas Incorporam, Hugh Lacey
Philosophy Faculty Works
Freqüentemente recorre-se à ciência para legitimar a prioridade atribuída ao desenvolvimento de sementes transgênicas na pesquisa agronômica, e a proteção privilegiada concedida aos direitos de propriedade intelectual sobre tais sementes. Alega-se que as sementes transgênicas incorporam conhecimento científico, mas não as sementes selecionadas na agricultura tradicional; e que o conhecimento científico sustenta não haver, além da agricultura que faz uso substancial de sementes transgênicas, maneira alternativa nenhuma de alimentar a humanidade. Ambas as alegações são questionadas por meio de um argumento que reconhece na agroecologia uma séria alternativa (pelo menos parcialmente) à predominância da biotecnologia na agricultura, uma alternativa que …

Legal Rites: Abjection And The Criminal Regulation Of Consensual Sex, Kate Sutherland
Legal Rites: Abjection And The Criminal Regulation Of Consensual Sex, Kate Sutherland
Articles & Book Chapters
The application of criminal law to consensual sex is an arena of conflict and contest between conservative and liberal forces in the United States, with occasional feminist interventions. The same arguments tend to recur on each side of the debate. Conservatives assert the appropriateness and necessity of enforcing a particular Judeo-Christian sexual morality through law. Liberals argue for tolerance of private consensual sexual conduct. When the debate shifts from the private to the public arena, conservatives may argue privacy principles, asserting the right of bystanders to be let alone, whereas liberals may shift to freedom of expression arguments. In this …

Hypothetical Origins Of Paleozoic Fossils From The Gulf Coastal Plain Of Arkansas, Karen Arbuckle
Hypothetical Origins Of Paleozoic Fossils From The Gulf Coastal Plain Of Arkansas, Karen Arbuckle
Journal of the Arkansas Academy of Science
A fauna of reworked Paleozoic fossils has been found in chert pebbles from the Gulf Coastal Plain in eastern Columbia County, Arkansas, although the nearest mapped exposure of Mississippian and Pennsylvanian rocks are fifty-five miles northward in the southern edge of the Ouachita Mountains. The surficial rocks at the collection site have been referred to the Claiborne Group of Eocene age by the authors of the geological map of Arkansas. Additional outcrops containing similar Paleozoic fossils have been found within a 15-mile radius. The fauna includes both lacy and twig-like bryozoans, articulate brachiopods, tabulate and rugose corals, stalked echinoderms, gastropods, …
Reaction Of Alpine-Borane With Aldehydes: Reactivity Rate Assessment By Observation Of The Disappearance Of The Carbonyl N - Pi* Peak By Uv-Visible Spectroscopy, Layla Bland, Michael J. Panigot
Reaction Of Alpine-Borane With Aldehydes: Reactivity Rate Assessment By Observation Of The Disappearance Of The Carbonyl N - Pi* Peak By Uv-Visible Spectroscopy, Layla Bland, Michael J. Panigot
Journal of the Arkansas Academy of Science
Due to an unexpectedly difficult reduction of indole-3-carbaldehyde and of isobutyraldehyde using the chiral reducing agent Alpine-Borane, the reactivity of several aliphatic, aromatic, and unsaturated aldehydes was investigated. This was done in order to determine whether there was a relationship between aldehyde structure and reduction rate. It was found that aliphatic aldehydes and aromatic aldehydes with no strongly electron-donating groups on the arene ring reduced faster than unsaturated aldehydes.

Growth Curves Of Four Species Of Commercially Valuable Freshwater Mussels (Bivalva: Unionidae), Alan D. Christian, Chris L. Davidson, William R. Posey Ii, Peter J. Rust, Jerry L. Farris, John L. Harris, George L. Harp
Journal of the Arkansas Academy of Science
North American freshwater mussels (Bivalvia: Unionidae) have been exploited commercially for over 100 years and have been regulated using shell size limits and/or harvest seasons. Presently, freshwater mussels are considered a threatened faunal group in North America due to the large numbers of endangered, threatened or special concern species. Therefore, management of this fauna should emphasize their long-term sustainability. The objectives of this study were 1) to construct von Bertalanffy growth curves for selected "commercially-most-valuable" species, Fusconaia ebena, Megalonaias nervosa, Amblema plicata and Quadrula quadrula, from five rivers and two reservoirs, 2) to compare species-specific von Bertalanffy growth curves from …

Physicochemical Characteristics And Macroinvertebrate Assemblages Of Riffles Upstream And Downstream Of A Streambank Impacted By Unrestricted Cattle Access, Ronald L. Johnson, Daniel D. Ward, Richard S. Grippo
Journal of the Arkansas Academy of Science
Riparian zones are important contributors to stream ecosystem health. Alteration of such areas can change stream structure and function, resulting in modified productivity and hydrologic patterns. We studied two riffle sites on the South Fork of the Spring River in Fulton County, AR upstream and downstream of a streambank ostensibly degraded by unrestricted cattle access. The two sites were measured for differences in physical habitat (including bank width, stream velocity, depth, substrate composition, and embeddedness), chemical characteristics (including dissolved oxygen, pH, conductivity, turbidity and total suspended solids) and biological characteristics (including benthic macroinvertebrate community composition, similarity, and standing crop). Measurements …
Method To Predict The Potential Regional Long-Term Timber Supply Using Gis And Other Publicly Available Data, Jeffery Earl, Richard A. Kluender, Robert Brewington
Method To Predict The Potential Regional Long-Term Timber Supply Using Gis And Other Publicly Available Data, Jeffery Earl, Richard A. Kluender, Robert Brewington
Journal of the Arkansas Academy of Science
While the global demand for wood products is on the rise, timber production has shifted from the Pacific Northwest to the southeastern United States in recent times. The increase in harvesting makes accurate assessment of the South's wood supply essential. Anew method is proposed for looking at the potential supply of raw woody material. The test area was three southeastern Arkansas counties. A geographic information system (GIS) using ArcView software incorporates two sources of public information. First, Forest Inventory and Analysis (FIA) data from the USDA Forest Service were queried to find land areas and volumes by timber type, as …

Home Ranges And Movements Of Adult Deer On Fort Chaffee, Arkansas, Gregory G. Humphreys, Thomas A. Nelson
Home Ranges And Movements Of Adult Deer On Fort Chaffee, Arkansas, Gregory G. Humphreys, Thomas A. Nelson
Journal of the Arkansas Academy of Science
We radio-tracked 27 white-tailed deer (Odocoileus virginianus) weekly for one year on Fort Chaffee, Arkansas, to investigate their seasonal home ranges and movements between hunted areas and refuges on this military base. This work resulted in2,123 separate radiolocations, of which 85% (1,799) were suitable for use in home range analyses. We used the McPAAL computer package to estimate home range using the Harmonic Mean and minimum convex polygon (MCP) methods. Harmonic mean estimates were based on 95% contour lines. Home range size differed between the sexes and methods. Male home ranges were larger than those of females (t= 3.32, P<0.01; harmonic mean) (t=2.07, P<0.05; MCP). Average home range sizes for males and females based on the harmonic mean method were estimated to be 483 ha and 181 ha, respectively, whereas home range estimates for males and females using the MCP method were 636 ha and 289 ha, respectively. The average home range size for all deer was 259 ha (harmonic mean) and 379 ha (MCP). We found no evidence that females restricted their home ranges during the fawning period. However, females' home ranges expanded during the breeding season, perhaps to find mates. Few deer moved to refuge areas that were off-limits to hunters during the hunting season.
