Simulations Of Quasigeostrophic Currents Derived From Satellite Altimetry And Acoustic Tomography Of An Open Ocean Region, Max I. Yaremchuk, Dmitri A. Nechaev Jan 2001

Simulations Of Quasigeostrophic Currents Derived From Satellite Altimetry And Acoustic Tomography Of An Open Ocean Region, Max I. Yaremchuk, Dmitri A. Nechaev

Faculty Publications

Acoustic tomography (AT) and satellite altimetry (SA) measure properties of the ocean state with high temporal resolution. That makes these data suitable for long-term monitoring of mesoscale features in the open ocean regions, where the open boundaries are the major sources of model forecast uncertainties on timescales larger than 1 week. In this paper, a finite-difference quasigeostrophic model of an open ocean region is considered as a possible tool for interpolating AT-SA data in space and time. The assimilation algorithm is based upon the 4D variational data assimilation scheme controlled by the initial and boundary conditions of the model. The …

Identifying A Damped Oscillatory Thermohaline Mode In A General Circulation Model Using An Adjoint Model, Ziv Sirkes, Eli Tziperman Jan 2001

Identifying A Damped Oscillatory Thermohaline Mode In A General Circulation Model Using An Adjoint Model, Ziv Sirkes, Eli Tziperman

Faculty Publications

A damped oscillatory mode of the thermohaline circulation (THC), which may play a role in interdecadal climate variability, is identified in a global primitive equation model. This analysis is done under mixed boundary conditions using an adjoint of the primitive equation model. The linearized versus nonlinear stability behavior of the model is studied by comparing the adjoint analysis to runs of the fully nonlinear model. It is shown that a steady-state solution obtained under larger amplitude freshwater surface forcing (and hence with a weaker North Atlantic overturning) is unstable, while a steady-state solution with stronger THC is stable. In a …

Approaches To Measuring Quality Of The Wilderness Experience, William T. Borrie, Robert M. Birzell Jan 2001

Approaches To Measuring Quality Of The Wilderness Experience, William T. Borrie, Robert M. Birzell

Society and Conservation Faculty Publications

Wilderness is a special place that provides opportunity for unique and profound experiences. An essential task for the maintenance of these recreational opportunities is the definition and monitoring of experience quality. Four approaches to the measurement of the wilderness experience have developed in over 30 years of research: satisfaction approaches (which focus on evaluation of onsite conditions), benefits-based approaches (focusing on psychological outcomes), experience-based approaches (describing cognitive states experienced in wilderness), and meanings-based approaches (documenting socially constructed meanings ascribed to the experience). Each approach has its strengths and weaknesses. Given that the wilderness experience is a multifaceted phenomenon, it is …

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley Jan 2001

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley

LSU Master's Theses

The objective of the first experiment was to determine the effects of storage at 22„aC vs. 4„aC on the motility and percentage of membrane-intact sperm (%MIS) of epididymal mouse sperm. Testicles were allocated into 22„aC or 4„aC treatment groups and stored for 24 or 48 hours. Additional testicles were allocated into the 4„aC treatment for storage for 72 or 96 hours. Sperm was collected and analyzed at each time point. Storage at 22„aC lowered motility and %MIS (P<0.05) when compared with control sperm and 4„aC sperm at both the 24 and 48 hours. Motility and %MIS of 4„aC sperm did not decrease when compared with the control until after 72 hours of storage. The second experiment evaluated the effects of 22„aC vs. 4„aC storage for 24 and 48 hours on epididymal dog sperm. Motility and %MIS of the 22„aC sperm was lower than that of the 4„aC sperm and the control (P<0.05) at 24 and 48 hours. Motility of the 4„aC sperm was lower than the control at 24 and 48 hours (P<0.05), however %MIS was not lower than the control until 48 hours. The third experiment tested the effect of cryopreservation on epididymal dog sperm. Sperm was frozen immediately (A), after 48 hours at 4„aC in liquid (B) or after 48 hours at 4„aC of the whole testicle (C). Both pre-freeze (PF) and post-thaw (PT) motility and %MIS of B and C were lower than A (P<0.05). PT values were lower than PF values in all treatments (P<0.05). PT motility of B was lower than C (0 vs. 35.0¡Ó3.6%). Storage at 4„aC allows collection of motile epididymal mouse and dog sperm for several days after death. Dog testicles can be refrigerated for 2 days and epididymal sperm frozen with PT motility and %MIS of 35 and 62%.

Development Of European Corn Borer Larvae On Event 176 Bt Corn: Influence On Survival And Fitness, Blair D. Siegfried, Amelia C. Zoerb, Terrence A. Spencer

Department of Entomology: Faculty Publications

European corn borer larvae, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae) that have completed development on Event 176 Bt corn hybrids have survived exposure to sublethal doses of the Cry1Ab Bt toxin or are exploiting plant tissues that do not express the toxin. To evaluate the impact of such exposure, diapausing larvae were collected from Event 176 and conventional hybrids and compared for rates of pupation, parasitism, fitness (pupal weight, longevity, and fecundity) and susceptibility to the Cry1Ab toxin. Larvae completing development on Event 176 corn exhibited approximately 10% higher survival rates and correspondingly lower parasitism rates than larvae completing development on …

Department of Entomology: Faculty Publications

We have previously determined that cytochrome P450-based oxidation is involved in resistance to the insecticides methyl parathion and carbaryl in geographically distinct Nebraska western corn rootworm populations. Three new family 4 cytochrome P450 (CYP4) gene fragments (CYP4AJ1, CYP4G18 and CYP4AK1) were cloned and sequenced from insecticide-resistant and -susceptible western corn rootworms. Insecticide bioassays indicated the resistant population employed in this study was significantly resistant to the insecticides methyl parathion and carbaryl. CYP4AJ1 and CYP4G18 were cloned from both genomic PCR and RT-PCR products, although only CYP4AJ1 contains an intronic region. Alignments of inferred amino acid sequences with other homologous insect …

The Stomatopod Alachosquilla Floridensis (Manning, 1962) (Crustacea, Stomatopoda, Nannosquillidae) Reported From Guana Island, British Virgin Islands, With Observations On Color, Joel W. Martin, Todd L. Zimmerman Jan 2001

The Stomatopod Alachosquilla Floridensis (Manning, 1962) (Crustacea, Stomatopoda, Nannosquillidae) Reported From Guana Island, British Virgin Islands, With Observations On Color, Joel W. Martin, Todd L. Zimmerman

Gulf and Caribbean Research

Although color pattern can vary among and within species of the Crustacea, it can also be a conservative feature that can be very helpful in field identifications. This is often the case in the Crustacea Decapoda, where sibling species can be detected by subtle differences in color (e.g., Williams and Felder 1989, Zimmerman and Felder 1991, Knowlton and Mills 1992). Stomatopods are among the most colorful crustaceans when living. Many species show a great deal of variability (Manning 1969, Camp 1973), and knowledge of this coloration is often key to their identification in the field and in the lab (Schotte …

Factors Mediating Cheatgrass Invasion Of Intact Salt Desert Shrubland, Susan E. Meyer, Susan Garvin, Julie Beckstead Jan 2001

Factors Mediating Cheatgrass Invasion Of Intact Salt Desert Shrubland, Susan E. Meyer, Susan Garvin, Julie Beckstead

Biology Faculty Scholarship

Cheatgrass (Bromus tectorum) has recently displaced salt desert shrubland in many areas of the Great Basin. We studied the dynamics of cheatgrass invasion into an intact shadscale-gray molly community in Dugway Valley, Utah, by adding seeds and manipulating disturbance regime and resource availability. Shrub clipping or cryptobiotic crust trampling on large plots increased cheatgrass recruitment and biomass production slightly in a favorable moisture year (1997 to 1998), whereas in a less favorable moisture year (1998 to 1999) these disturbance treatments had a significant negative effect. In 1998 to 1999 small plot studies, recruitment was similar in intact shrub clumps and …

Crossing Methodological Boundaries: Assessing Visitor Motivations And Support For Management Actions At Yellowstone National Park Using Quantitative And Qualitative Research Approaches, William T. Borrie, Wayne A. Freimund, Mae A. Davenport, Robert E. Manning Jan 2001

Crossing Methodological Boundaries: Assessing Visitor Motivations And Support For Management Actions At Yellowstone National Park Using Quantitative And Qualitative Research Approaches, William T. Borrie, Wayne A. Freimund, Mae A. Davenport, Robert E. Manning

Society and Conservation Faculty Publications

Winter use of Yellowstone National Park has given rise to a complex of management issues, including rapid growth in recreation demand, environmental impacts of snowmobiling, and a string of litigation against the National Park Service (NPS) designed to both protect park resources and maintain public access (Sacklin et al. 2000). The intertwined character of these problems suggests that none can be resolved independently of the other, that policy must be comprehensive in nature, and that many sources of knowledge may be required to effect their resolution.

Structural And Functional Characterization Of The Activator Of G-Protein Signaling 3 (Ags3), Michael Labranche Bernard Jan 2001

Structural And Functional Characterization Of The Activator Of G-Protein Signaling 3 (Ags3), Michael Labranche Bernard

MUSC Theses and Dissertations

AGS3 (Activator of G-protein Signaling 3) was isolated in yeast-based functional screen for receptor-independent activators of heterotrimeric G-proteins. To examine the role of AGS3 in mammalian signal processing, we defined the AGS3 sub domains involved in G-protein interaction, its selectivity for G-proteins and its influence on the activation state of G-protein. AGS3 co-immunoprecipitated with Gia3 from tissue lysates in a nucleotide dependent manner (GDP»GTPγS). The regions of AGS3 that bound Giα were localized to 4 thirty amino acid repeats (GPR - G-protein regulatory motif) in the carboxyl terminus (P463-S650), each of which were capable of binding Giα. AGS3-GPR domains selectively …
