Effects Of Selenium On The Freshwater Alga Chlamydomonas Reinhardtii With And Without The Proteasome Inhibitor Mg132, E. Patrick Vallentine Dec 2012

Effects Of Selenium On The Freshwater Alga Chlamydomonas Reinhardtii With And Without The Proteasome Inhibitor Mg132, E. Patrick Vallentine

Honors Theses

Selenium is a required nutrient in animal life but has not been shown to be needed in plants. The model plant cell Chlamydomonas reinhardtii may be an exception as it appears to increase its growth rate in the presence of selenium. Because selenium has the same valence state as sulfur it may be incorporated into proteins as the modified amino acid selenocysteine. This incorporation of selenocysteine into protein may disrupt the disulfide bridges that give proteins the correct conformation. Misfolded proteins can wreak havoc on a cell. This stress can be measured through several parameters. Chlorophyll levels, glutathione levels, growth, …

Life History Analysis Of James River Atlantic Sturgeon (Acipenser Oxyrinchus Oxyrinchus) With Implications For Management And Recovery Of The Species, Matthew Balazik Dec 2012

Life History Analysis Of James River Atlantic Sturgeon (Acipenser Oxyrinchus Oxyrinchus) With Implications For Management And Recovery Of The Species, Matthew Balazik

Theses and Dissertations

Sturgeon species (family Acipenseridae) are threatened globally due to habitat destruction, pollution, and overfishing. The Atlantic sturgeon Acipenser oxyrinchus oxyrinchus was listed as a federally endangered species in 2012. Atlantic sturgeon have a complex life history that utilizes a wide range of habitats. Timing of life history varies in different areas requiring each population to be studied. Very little work has been published on Atlantic sturgeon reproduction in the James River, Virginia. To aid the recovery of James River Atlantic sturgeon, aspects of life history need to be addressed. To increase understanding of Atlantic sturgeon life history a length at …

Individual Cell Growth Rates Of Marine Bacteria, Measured By Bromodeoxyuridine Incorporation, Koji Hamasaki, Richard A. Long, Farooq Azam Oct 2012

Individual Cell Growth Rates Of Marine Bacteria, Measured By Bromodeoxyuridine Incorporation, Koji Hamasaki, Richard A. Long, Farooq Azam

Richard A. Long

We tested the application of 5-bromo-2’-deoxyuridine (BrdU), a thymidine analogue that becomes incorporated into DNA during growth, to measure growth rates of individual marine bacteria cells. Immunocytochemical detection of BrdU incorporation into bacterial DNA has the potential for single-cell-based growth measurement. Optimized procedure for immunocytochemistry was applicable to 14 marine heterotrophic bacterial isolates belonging to g-proteobacteria, α-proteobacteria, Cytophaga-Flavobacterium-Bacteroides (CFB) group and Gram-positive bacteria. The relationship between cell-specific fluorescence intensity and specific growth rate was linearly correlated among CFB group isolates, which indicated a potential of the method for quantitative measurement. Analysis of the detection limit indicated …

Accordion Vs. Quantum Tectonics: Insights Into Continental Growth Processes From The Paleozoic Of Eastern Gondwanan, Jonathan C. Aitchison, Solomon Buckman Sep 2012

Accordion Vs. Quantum Tectonics: Insights Into Continental Growth Processes From The Paleozoic Of Eastern Gondwanan, Jonathan C. Aitchison, Solomon Buckman

Solomon Buckman Dr.

The Early Paleozoic Lachlan Fold Belt of eastern Australia is widely regarded as an ancient convergent plate margin beneath which paleo-Pacific (Panthalassic) oceanic lithosphere was continuously subducted. It is cited as the type example of a retreating accretionary orogeny. However, sandstone compositions, the sedimentological nature and timing of chert accumulation and overall stratigraphic architecture are not necessarily consistent with this model. We suggest an alternative explanation for growth of Gondwanan continental margin. Oceanic lithosphere outboard of the passive Gondwana continental margin was subducted beneath an extensive intra-oceanic island arc that now crops out as an allochthonous element (Macquarie arc) within …

Effects Of Pristane On Growth Of Pink Salmon (Oncorhynchus Gorbuscha), Brielle D. Kemis, Bonita Nelson Aug 2012

Effects Of Pristane On Growth Of Pink Salmon (Oncorhynchus Gorbuscha), Brielle D. Kemis, Bonita Nelson

STAR Program Research Presentations

Pristane is a naturally occurring hydrocarbon that is generated by copepods in marine ecosystems. Organisms that eat copepods do not readily metabolize pristane, which causes it to accumulate throughout the marine food web. Understanding how pristane affects marine fish is essential because pristane is often used as a bioindicator in lab studies and may be influencing results in those studies. Also, this hydrocarbon may significantly reduce growth of marine fish in the wild. A previous study indicated that pristane is an appetite suppressant and growth retardant in fish. However, the study implemented a feeding regime with unnaturally high levels of …

The Effect Of Photoperiod On Regulation Of Key Components Of The Life Cycle In The Bumble Bee Bombus Impatiens L. (Hymenoptera: Apidae)., Edgar Javier Hernandez May 2012

The Effect Of Photoperiod On Regulation Of Key Components Of The Life Cycle In The Bumble Bee Bombus Impatiens L. (Hymenoptera: Apidae)., Edgar Javier Hernandez

Dissertations

This study investigates how photoperiod affects internal characteristics of colonies of the temperate bumble bee Bombus impatiens particularly; development, reproduction, and social behavior. To answer this question I used an experimental approach using commercially obtained colonies of B. impatiens kept under controlled environmental conditions, and using the exposure to photoperiod as the only variable. Eight different photoperiod treatments were evaluated over the social phase of the colony’s life cycle. Colonies exposed to photoperiods that simulate the species natural temperate photoperiod exhibited larger growth rates, higher, oviposition rates, and higher brood survival than colonies exposed to constant photoperiods. Similarly, colonies exposed …

Elucidating The Effect Of Silver On Ethylene Signaling In Arabidopsis Thaliana, Brittany Kathleen Mcdaniel May 2012

Elucidating The Effect Of Silver On Ethylene Signaling In Arabidopsis Thaliana, Brittany Kathleen Mcdaniel

Masters Theses

Ethylene, a gaseous plant hormone, is involved in numerous plant developmental processes such as seed germination, senescence, and fruit ripening. In Arabidopsis thaliana, ethylene is perceived by a family of five membrane-bound receptors, which upon binding ethylene trigger downstream effects. At the receptor level, it is known that the coordination of a copper ion is necessary for ethylene to bind, resulting in a conformational change of the receptor and the initiation of the ethylene signal transduction pathway. Interestingly, silver ions are also able to support binding of ethylene but ethylene responses are blocked in the presence of silver. When …

Predicting The Physiological Performance Of Ectotherms In Fluctuating Thermal Environments, Michael W. Sears, A C. Niehaus, M J. Angilletta, C E. Franklin, R S. Wilson Feb 2012

Predicting The Physiological Performance Of Ectotherms In Fluctuating Thermal Environments, Michael W. Sears, A C. Niehaus, M J. Angilletta, C E. Franklin, R S. Wilson

Publications

Physiological ecologists have long sought to understand the plasticity of organisms in environments that vary widely among years, seasons and even hours. This is now even more important because human-induced climate change is predicted to affect both the mean and variability of the thermal environment. Although environmental change occurs ubiquitously, relatively few researchers have studied the effects of fluctuating environments on the performance of developing organisms. Even fewer have tried to validate a framework for predicting performance in fluctuating environments. Here, we determined whether reaction norms based on performance at constant temperatures (18, 22, 26, 30 and 34°C) could be …

Temperature Effects On Growth And Stress Physiology Of Brook Trout: Implications For Climate Change Impacts On An Iconic Cold-Water Fish, Joseph G. Chadwick Jr Jan 2012

Temperature Effects On Growth And Stress Physiology Of Brook Trout: Implications For Climate Change Impacts On An Iconic Cold-Water Fish, Joseph G. Chadwick Jr

Masters Theses 1911 - February 2014

Despite the threat of climate change, the physiological mechanisms by which temperature drives the distribution of species are unclear. Here we used chronic temperature exposures to determine that the upper limit for positive growth in the eastern brook trout (Salvelinus fontinalis) is 23.4 °C. Additionally, brook trout exposed to daily temperature oscillations of 8 °C, around a mean of 21 °C, exhibited growth rates that were 43 and 35% lower by length and weight respectively, than in constant 21 °C controls. Limitations in growth were associated with increases in indicators of the physiological stress response. Individuals exposed to …

Short-Term Carbon Partitioning Fertilizer Responses Vary Among Two Full-Sib Loblolly Pine Clones, Jeremy P. Stovall, John R. Seiler, Thomas R. Fox Jan 2012

Short-Term Carbon Partitioning Fertilizer Responses Vary Among Two Full-Sib Loblolly Pine Clones, Jeremy P. Stovall, John R. Seiler, Thomas R. Fox

Faculty Publications

We investigated the effects of fertilizer application on the partitioning of gross primary productivity (GPP) between contrasting full-sib clones of Pinus taeda (L.). Our objective was to determine if fertilizer growth responses resulted from similar short-term changes to partitioning. A modeling approach incorporating respiratory carbon (C) fluxes, soil CO2 efflux (FS), and biomass was applied to a factorial design with two clones, fertilizer and control treatments, and four sequential monthly harvests of seedlings planted in a greenhouse. Partitioning was integrated over 121 days to above, belowground, and total net primary production (ANPP + BNPP = NPP), total belowground C flux …

On The Life History Of Spirlin Alburnoides Bipunctatus (Bloch, 1782) In The Qanat Of Uzineh, Northern Iran, Rahman Patimar, Mohsen Zare, Mehdi Hesam Jan 2012

On The Life History Of Spirlin Alburnoides Bipunctatus (Bloch, 1782) In The Qanat Of Uzineh, Northern Iran, Rahman Patimar, Mohsen Zare, Mehdi Hesam

Turkish Journal of Zoology

Within the wide distribution of spirlin in Iran, populations of this species inhabit a great variety of habitats, including qanats. We hypothesized that qanats may contribute to habitat-specific variation in the life history of the fish. To test this, a total of 240 specimens of Alburnoides bipunctatus, caught in the qanat of Uzineh (northern Iran) from October 2007 to August 2008, were examined for life history attributes. The population had a 5-year life cycle. The weight-length relationship (WLR) was estimated as W = 0.0068TL^{3.2559} for males, W = 0.0079TL^{3.2067} for females, and W = 0.0072TL^{3.2387} for the population, having a …

Growth Performance And Body Composition Of Kutum Fingerlings, Rutilus Frisii Kutum (Kamenskii 1901),In Response To Dietary Protein Levels, Ghaffar Ebrahimi, Hossein Ouraji

Turkish Journal of Zoology

A feeding trial was conducted to determine the optimal dietary crude protein requirement for Rutilus frisii kutum fingerlings. Five isoenergetic experimental diets were formulated to contain graded levels of protein (32%, 37%, 42%, 47%, and 52%). Triplicate groups of 80 kutum (average weight 0.5 g) were stocked in 250-L tanks and fed to apparent satiation 3 times a day for 8 weeks. The results indicate that the growth performance and feed utilization of kutum were significantly (P < 0.05) affected by dietary protein level. The second polynomial regression of weight gain against protein level yielded an estimated optimal dietary protein requirement of 41.6%. Weight gain, specific growth rate, and feed efficiency increased with increasing the dietary protein level from 32% to 42%, but decreased significantly (P < 0.05) with further increases in dietary protein. The protein efficiency ratio was inversely correlated with dietary protein level. Feed intake was not affected (P > 0.05) by dietary protein level. No significant difference was found in the whole-body protein, lipid, moisture, or ash contents of fish fed the …

Identification Of New Cell Size Control Genes In S. Cerevisiae, Huzefa Dungrawala, Hui Hua, Jill Wright, Lesley Abraham, Thivakorn Kasemsri, Anthony Mcdowell, Jessica Stilwell, Brandt L. Schneider Jan 2012

Identification Of New Cell Size Control Genes In S. Cerevisiae, Huzefa Dungrawala, Hui Hua, Jill Wright, Lesley Abraham, Thivakorn Kasemsri, Anthony Mcdowell, Jessica Stilwell, Brandt L. Schneider

Molecular Biosciences Faculty Publications

Cell size homeostasis is a conserved attribute in many eukaryotic species involving a tight regulation between the processes of growth and proliferation. In budding yeast S. cerevisiae, growth to a “critical cell size” must be achieved before a cell can progress past START and commit to cell division. Numerous studies have shown that progression past START is actively regulated by cell size control genes, many of which have implications in cell cycle control and cancer. Two initial screens identified genes that strongly modulate cell size in yeast. Since a second generation yeast gene knockout collection has been generated, we screened …
