Changes In Sublethal Effects And Lead Accumulation In Acanthopagrus Latus Under Various Lead Concentrations And Salinities, Wen-Ching Tsui, Jiann-Chu Chen, Sha-Yen Cheng Oct 2016

Changes In Sublethal Effects And Lead Accumulation In Acanthopagrus Latus Under Various Lead Concentrations And Salinities, Wen-Ching Tsui, Jiann-Chu Chen, Sha-Yen Cheng

Journal of Marine Science and Technology–Taiwan

This study investigated the sublethal concentration of lead and calcium levels in yellowfin seabream juvenile (Acanthopagrus latus) (4.367 ± 0.470 cm; 1.408± 0.478 g) following exposure to a series of lead concentrations at various salinities (0‰, 9‰, 17‰, 25‰ and 34‰). Yellowfin seabream juveniles exposed to 17‰ salinity were the most tolerant to lead. After 96-h, the 50% lethal concentration (LC50) values were 0.33, 1.43, 3.78, 2.32 and 1.46 mg Pb2+ /L following exposure to 0‰, 9‰, 17‰, 25‰ and 34‰ salinities, respectively. The 6-, 12-, 24-, 48- and 96-h LC50 for fish exposed to 17‰ salinity were 124.67, 33.02, …

Coastal Wetland Response To Sea-Level Rise In A Fluvial Estuarine System, Karim Alizad, Scott C. Hagen, James T. Morris, Stephen C. Medeiros, Matthew V. Bilskie, John F. Weishampel

Faculty Publications

Coastal wetlands are likely to lose productivity under increasing rates of sea-level rise (SLR). This study assessed a fluvial estuarine salt marsh system using the Hydro-MEM model under four SLR scenarios. The Hydro-MEM model was developed to apply the dynamics of SLR as well as capture the effects associated with the rate of SLR in the simulation. Additionally, the model uses constants derived from a 2-year bioassay in the Apalachicola marsh system. In order to increase accuracy, the lidar-based marsh platform topography was adjusted using Real Time Kinematic survey data. A river inflow boundary condition was also imposed to simulate …

The prion protein (PrPC) has been suggested to operate as a scaffold/receptor protein in neurons, participating in both physiological and pathological associated events. PrPC, laminin, and metabotropic glutamate receptor 5 (mGluR5) form a protein complex on the plasma membrane that can trigger signaling pathways involved in neuronal differentiation. PrPC and mGluR5 are co-receptors also for -amyloid oligomers (AOs) and have been shown to modulate toxicity and neuronal death in Alzheimer's disease. In the present work, we addressed the potential crosstalk between these two signaling pathways, laminin-PrPC-mGluR5 or AO-PrPC-mGluR5, as well as their interplay. Herein, we demonstrated that an existing complex …

Hearing In The Juvenile Green Sea Turtle (Chelonia Mydas): A Comparison Of Underwater And Aerial Hearing Using Auditory Evoked Potentials, Wendy E D Piniak, David A Mann, Craig A Harms, T Todd Jones, Scott A Eckert

Marine Science Faculty Publications

Sea turtles spend much of their life in aquatic environments, but critical portions of their life cycle, such as nesting and hatching, occur in terrestrial environments, suggesting that it may be important for them to detect sounds in both air and water. In this study we compared underwater and aerial hearing sensitivities in five juvenile green sea turtles (Chelonia mydas) by measuring auditory evoked potential responses to tone pip stimuli. Green sea turtles detected acoustic stimuli in both media, responding to underwater stimuli between 50 and 1600 Hz and aerial stimuli between 50 and 800 Hz, with maximum sensitivity between …


A Lota Lota Consumption: Trophic Dynamics Of Non-Native Burbot In A Valuable Sport Fishery, Stephen L. Klobucar, W. Carl Saunders, Phaedra Budy Oct 2016

A Lota Lota Consumption: Trophic Dynamics Of Non-Native Burbot In A Valuable Sport Fishery, Stephen L. Klobucar, W. Carl Saunders, Phaedra Budy

Watershed Sciences Student Research

Unintentional and illegal introductions of species disrupt food webs and threaten the success of managed sport fisheries. Although many populations of Burbot Lota lota are declining in the species’ native range, a nonnative population recently expanded into Flaming Gorge Reservoir (FGR), Wyoming–Utah, and threatens to disrupt predator–prey interactions within this popular sport fishery. To determine potential impacts on sport fishes, especially trophy Lake Trout Salvelinus namaycush, we assessed the relative abundance of Burbot and quantified the potential trophic or food web impacts of this population by using diet, stable isotope, and bioenergetic analyses. We did not detect a significant …

Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott Oct 2016

Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott

Emotion Collection

Animal emotional states can be investigated by evaluating their impact on cognitive processes. In this study, we used a judgement bias paradigm to determine if shortterm positive human-animal interaction (grooming) induced a positive affective state in goats. We tested two groups of goats and trained them to discriminate between a rewarded and a non-rewarded location over nine training days. During training, the experimental group (nD9) was gently groomed by brushing their heads and backs for five min over 11 days (nine training days, plus two testing days, total time 55 min). During training, the control group (nD10) did not experience …

Streptococcus pyogenes (Group A Streptococcus or GAS) is a hemolytic human pathogen associated with a wide variety of infections ranging from minor skin and throat infections to life-threatening invasive diseases. The cell wall of GAS consists of peptidoglycan sacculus decorated with a carbohydrate comprising a polyrhamnose backbone with immunodominant N-acetylglucosamine side-chains. All GAS genomes contain the spyBA operon, which encodes a 35-amino-acid membrane protein SpyB, and a membrane-bound C3-like ADP-ribosyltransferase SpyA. In this study, we addressed the function of SpyB in GAS. Phenotypic analysis of a spyB deletion mutant revealed increased bacterial aggregation, and reduced sensitivity to β-lactams of the …


Processes Of Multibathyal Aragonite Undersaturation In The Arctic Ocean, Jonathan G. Wynn, Lisa Robbins, L. G. Anderson Oct 2016

Processes Of Multibathyal Aragonite Undersaturation In The Arctic Ocean, Jonathan G. Wynn, Lisa Robbins, L. G. Anderson

School of Geosciences Faculty and Staff Publications

During 3 years of study (2010–2012), the western Arctic Ocean was found to have unique aragonite saturation profiles with up to three distinct aragonite undersaturation zones. This complexity is produced as inflow of Atlantic‐derived and Pacific‐derived water masses mix with Arctic‐derived waters, which are further modified by physiochemical and biological processes. The shallowest aragonite undersaturation zone, from the surface to ∼30 m depth is characterized by relatively low alkalinity and other dissolved ions. Besides local influence of biological processes on aragonite undersaturation of shallow coastal waters, the nature of this zone is consistent with dilution by sea‐ice melt and invasion …


Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith Oct 2016

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith

Southeastern Fishes Council Proceedings

Many river-dwelling species of fish are dependent upon and stimulated by fluctuations in river flow for successful reproduction. This is especially true of pelagophils, a reproductive guild whose eggs and larvae require free drifting on river currents for several days. Notropis photogenis (Silver Shiner) is a rheophilic species with a broad distribution from Ontario to the southeastern United States including northern tributaries to the Tennessee River in Alabama. Little is known of its reproductive biology. The purpose of this study was to describe aspects of reproductive biology such as timing and pattern of ovarian development and oocyte maturation of N. …

Aneuploidy: A Common And Early Evidence-Based Biomarker For Carcinogens And Reproductive Toxicants., Daniele Mandrioli, Fiorella Belpoggi, Ellen K Silbergeld, Melissa J. Perry Oct 2016

Aneuploidy: A Common And Early Evidence-Based Biomarker For Carcinogens And Reproductive Toxicants., Daniele Mandrioli, Fiorella Belpoggi, Ellen K Silbergeld, Melissa J. Perry

Environmental and Occupational Health Faculty Publications

Aneuploidy, defined as structural and numerical aberrations of chromosomes, continues to draw attention as an informative effect biomarker for carcinogens and male reproductive toxicants. It has been well documented that aneuploidy is a hallmark of cancer. Aneuploidies in oocytes and spermatozoa contribute to infertility, pregnancy loss and a number of congenital abnormalities, and sperm aneuploidy is associated with testicular cancer. It is striking that several carcinogens induce aneuploidy in somatic cells, and also adversely affect the chromosome compliment of germ cells. In this paper we review 1) the contributions of aneuploidy to cancer, infertility, and developmental abnormalities; 2) techniques for …

Bioinformatics Faculty Publications

The genus Escherichia includes pathogens and commensals. Bladder infections (cystitis) result most often from colonization of the bladder by uropathogenic E. coli strains. In contrast, a poorly defined condition called asymptomatic bacteriuria results from colonization of the bladder with E. coli strains without symptoms. As part of an on-going attempt to identify and characterize the newly discovered female urinary microbiota, we report the genome sequences and annotation of two urinary isolates of E. coli: one (E78) was isolated from a female patient who self-reported cystitis; the other (E75) was isolated from a female patient who reported that she did …


Purification Of 26s Proteasomes And Their Subcomplexes From Plants, Richard S. Marshall, David C. Gemperline, Richard D. Vierstra Oct 2016

Purification Of 26s Proteasomes And Their Subcomplexes From Plants, Richard S. Marshall, David C. Gemperline, Richard D. Vierstra

Biology Faculty Research

The 26S proteasome is a highly dynamic, multisubunit, ATP-dependent protease that plays a central role in cellular housekeeping and many aspects of plant growth and development by degrading aberrant polypeptides and key cellular regulators that are first modified by ubiquitin. Although the 26S proteasome was originally enriched from plants over 30 years ago, only recently have significant advances been made in our ability to isolate and study the plant particle. Here, we describe two robust methods for purifying the 26S proteasome and its subcomplexes from Arabidopsis thaliana; one that involves conventional chromatography techniques to isolate the complex from wild-type …
