Estimating Waterfowl Carrying Capacity At Local Scales: A Case Study From Edwin B. Forsythe National Wildlife Refuge, New Jersey, Kevin M. Ringelman, Christopher K. Williams, Paul M. Castelli, Mason L. Sieges, Rebecca A. Longenecker, Theodore C. Nichols, Stephen D. Earsom

Faculty Publications

The management of wintering North American waterfowl is based on the premise that the amount of foraging habitat can limit populations. To estimate carrying capacity of winter habitats, managers use bioenergetic models to quantify energy (food) availability and energy demand, and use results as planning tools to meet regional conservation objectives. Regional models provide only coarse estimates of carrying capacity because habitat area, habitat energy values, and temporal trends in population-level demand are difficult to quantify precisely at large scales. We took advantage of detailed data previously collected on wintering waterfowl at Edwin B. Forsythe National Wildlife Refuge and surrounding …

Faculty Publications

Multi-environment trials are routinely conducted in plant breeding to select candidates for the next selection cycle. In this study, we compare the prediction accuracy of four developed genomic-enabled prediction models: (1) single-environment, main genotypic effect model (SM); (2) multi-environment, main genotypic effects model (MM); (3) multi-environment, single variance G×E deviation model (MDs); and (4) multi-environment, environment-specific variance G×E deviation model (MDe). Each of these four models were fitted using two kernel methods: a linear kernel Genomic Best Linear Unbiased Predictor, GBLUP (GB), and a nonlinear kernel Gaussian kernel (GK). The eight model-method combinations were applied to two extensive Brazilian maize …

Oxidative Stress Following Plga Nanoparticles Administration To An Animal Model, Daniela Miricescu, Iulia Stanescu, Paula Perlea, Bogdan Calenic, Radu Radulescu, Alexandra Totan, Bogdana Virgolici, Cristina Sabliov, Maria Greabu Jun 2017

Oxidative Stress Following Plga Nanoparticles Administration To An Animal Model, Daniela Miricescu, Iulia Stanescu, Paula Perlea, Bogdan Calenic, Radu Radulescu, Alexandra Totan, Bogdana Virgolici, Cristina Sabliov, Maria Greabu

Faculty Publications

In the recent years, engineered nanoparticles (NPs) such as PLGA or poly-lactic-co-glycolic acid, have raised a substantial interest due to their possible medical applications in vaccination, diagnostic imaging procedures, cancer therapy or sustained delivery of drugs. The main aim of the present work is to evaluate key oxidative stress parameters in several organs following NPs administration in an animal model. Our data shows that acute oral administration of PLGA NPs induces a change in the antioxidant status in both rat liver and spleen, but may not induce oxidative stress damage to cell structures such as lipid or protein oxidation.

© 2017 by the authors. Future conditions of coastal Louisiana are highly uncertain due to the dynamic nature of deltas, climate change, tropical storms, and human reliance on natural resources and ecosystem services. Managing a system in which natural and socio-economic components are highly integrated is inherently difficult. Sediment diversions are a unique restoration tool that would reconnect the Mississippi River to its deltaic plain to build and sustain land. Diversions are innately adaptable as operations can be modified over time. An expert working group was formed to explore how various operational strategies may affect the complex interactions of coastal …

Message from President: Followers of the headlines relish big events, whether mammoth economic downturns or raging battles or colossal storms. Leaders, especially those of the academic kind, most often deal with small events, whether the rotation of Chairs in a tiny department or the bursting of a water main on a satellite campus or declining enrollments in an unfashionable curriculum. Those seeking the reasons for the troubles faced by Louisiana higher education institutions might be well-advised to narrow their inquiries: to consider the role of the incremental in building or dissolving the grand—in, as it were, gradually pushing up or …

© 2017, Copyright © Taylor & Francis Group, LLC. Epidemiological studies indicate that the increased consumption of sugars including sucrose and fructose in beverages correlate with the prevalence of obesity, type-2 diabetes, insulin resistance, hyperinsulinemia, hypertriglyceridemia, and hypertension in humans. A few reports suggest that fructose extends lifespan in Saccharomyces cerevisiae. In Anopheles gambiae, fructose, glucose, or glucose plus fructose also extended lifespan. New results presented here suggest that fructose extends lifespan in Caenorhabditis elegans (C. elegans) wild type (N2). C. elegans were fed standard laboratory food source (E. coli OP50), maintained in liquid culture. Experimental groups received additional glucose …

Redox-Sensitive Marr Homologue Bifr From Burkholderia Thailandensis Regulates Biofilm Formation, Ashish Gupta, Stanley M. Fuentes, Anne Grove May 2017

Redox-Sensitive Marr Homologue Bifr From Burkholderia Thailandensis Regulates Biofilm Formation, Ashish Gupta, Stanley M. Fuentes, Anne Grove

Faculty Publications

© 2017 American Chemical Society. Biofilm formation by pathogenic Burkholderia species is a serious complication as it renders the bacteria resistant to antibiotics and host defenses. Using B. thailandensis, we report here a novel redox-sensitive member of the multiple antibiotic resistance regulator (MarR) protein family, BifR, which represses biofilm formation. BifR is encoded as part of the emrB-bifR operon; emrB-bifR is divergent to ecsC, which encodes a putative LasA protease. In Pseudomonas aeruginosa, LasA has been implicated in virulence by contributing to cleavage of elastase. BifR repressed the expression of ecsC and emrB-bifR, and expression was further repressed under oxidizing …

Predicting Cryptic Links In Host-Parasite Networks, Tad Dallas, Andrew W. Park, John M. Drake May 2017

Predicting Cryptic Links In Host-Parasite Networks, Tad Dallas, Andrew W. Park, John M. Drake

Faculty Publications

© 2017 Dallas et al. Networks are a way to represent interactions among one (e.g., social networks) or more (e.g., plant-pollinator networks) classes of nodes. The ability to predict likely, but unobserved, interactions has generated a great deal of interest, and is sometimes referred to as the link prediction problem. However, most studies of link prediction have focused on social networks, and have assumed a completely censused network. In biological networks, it is unlikely that all interactions are censused, and ignoring incomplete detection of interactions may lead to biased or incorrect conclusions. Previous attempts to predict network interactions have relied …

Hypertension is a leading cause of global disease, mortality, and disability. While individuals of African descent suffer a disproportionate burden of hypertension and its complications, they have been underrepresented in genetic studies. To identify novel susceptibility loci for blood pressure and hypertension in people of African ancestry, we performed both single and multiple-trait genome-wide association analyses. We analyzed 21 genome-wide association studies comprised of 31,968 individuals of African ancestry, and validated our results with additional 54,395 individuals from multi-ethnic studies. These analyses identified nine loci with eleven independent variants which reached genome-wide significance (P < 1.25×10−8) for either systolic and diastolic blood pressure, hypertension, or for combined traits. Single-trait analyses identified two loci (TARID/TCF21 and LLPH/TMBIM4) and multiple-trait analyses identified one novel locus (FRMD3) for blood pressure. At these three loci, as well as at GRP20/CDH17, associated variants had alleles common only in African-ancestry populations. Functional annotation showed enrichment for genes expressed in immune and kidney cells, as well as in heart and vascular cells/tissues. Experiments driven by these findings and using angiotensin-II induced hypertension in mice showed altered kidney mRNA expression of six genes, suggesting their potential role in hypertension. Our study provides new evidence for genes related to hypertension susceptibility, and the need to study African-ancestry populations in order to identify biologic factors contributing to hypertension.

Sacral Variability In Tailless Species: Homo Sapiens And Ochotona Princeps, Robert G. Tague May 2017

Sacral Variability In Tailless Species: Homo Sapiens And Ochotona Princeps, Robert G. Tague

Faculty Publications

Homo sapiens is variable in number of sacral vertebrae, and this variability can lead to obstetrical complication. This study uses the comparative method to test the hypothesis that sacral variability in H. sapiens is associated with absence of a tail. Three species of lagomorphs are studied: Ochotona princeps (N = 271), which is tailless, and Lepus californicus (N = 212) and Sylvilagus audubonii (N = 206), which have tails. Results show that O. princeps has (1) higher diversity index for number of sacral vertebrae (0.49) compared to L. californicus (0.25) and S. audubonii (0.26) and (2) significantly higher percentage of …

Population Genetic Inferences Using Immune Gene Snps Mirror Patterns Inferred By Microsatellites, Jean P. Elbers, Rachel W. Clostio, Sabrina S. Taylor May 2017

Population Genetic Inferences Using Immune Gene Snps Mirror Patterns Inferred By Microsatellites, Jean P. Elbers, Rachel W. Clostio, Sabrina S. Taylor

Faculty Publications

Single nucleotide polymorphisms (SNPs) are replacing microsatellites for population genetic analyses, but it is not apparent how many SNPs are needed or how well SNPs correlate with microsatellites. We used data from the gopher tortoise, Gopherus polyphemus—a species with small populations, to compare SNPs and microsatellites to estimate population genetic parameters. Specifically, we compared one SNP data set (16 tortoises from four populations sequenced at 17 901 SNPs) to two microsatellite data sets, a full data set of 101 tortoises and a partial data set of 16 tortoises previously genotyped at 10 microsatellites. For the full microsatellite data set, observed …

Aflatoxin, produced by Aspergillus flavus, is hazardous to health of humans and livestock. The lack of information about large effect QTL for resistance to aflatoxin accumulation is a major obstacle to employ marker-assisted selection for maize improvement. The understanding of resistance mechanisms of the host plant and the associated genes is necessary for improving resistance to A. flavus infection. A suppression subtraction hybridization (SSH) cDNA library was made using the developing kernels of Mp715 (resistant inbred) and B73 (susceptible inbred) and 480 randomly selected cDNA clones were sequenced to identify differentially expressed genes (DEGs) in response to A. flavus infection …

Bile Acid Sodium Symporter Bass6 Can Transport Glycolate And Is Involved In Photorespiratory Metabolism In Arabidopsis Thaliana, Paul F. South, Berkley J. Walker, Amanda P. Cavanagh, Vivien Rolland, Murray Badger, Donald R. Ort

Faculty Publications

© 2017, American Society of Plant Biologists. All rights reserved. Photorespiration is an energy-intensive process that recycles 2-phosphoglycolate, a toxic product of the Rubisco oxygenation reaction. The photorespiratory pathway is highly compartmentalized, involving the chloroplast, peroxisome, cytosol, and mitochondria. Though the soluble enzymes involved in photorespiration are well characterized, very few membrane transporters involved in photorespiration have been identified to date. In this work, Arabidopsis thaliana plants containing a T-DNA disruption of the bile acid sodium symporter BASS6 show decreased photosynthesis and slower growth under ambient, but not elevated CO2. Exogenous expression of BASS6 complemented this photorespiration mutant phenotype. In …
