A Cadmium-Transporting PIb-Type Atpase In Yeast Saccharomyces Cerevisiae, David J. Adle, Devis Sinani, Heejeong Kim, Jaekwon Lee

Department of Biochemistry: Faculty Publications

Detoxification and homeostatic acquisition of metal ions are vital for all living organisms. We have identified PCA1 in yeast Saccharomyces cerevisiae as an overexpression suppressor of copper toxicity. PCA1 possesses signatures of a P_IB-type heavy metal-transporting ATPase that is widely distributed from bacteria to humans. Copper resistance conferred by PCA1 is not dependent on catalytic activity, but it appears that a cysteine-rich region located in the N terminus sequesters copper. Unexpectedly, when compared with two independent natural isolates and an industrial S. cerevisiae strain, the PCA1 allele of the common laboratory strains we have examined possesses a missense …

Developmental Risks And Psychosocial Adjustment Among Low-Income Brazilian Youth, Marcela Raffaelli, Silvia H. Koller, Elder Cerqueria-Santos, Normanda Araujo De Morais

Department of Psychology: Faculty Publications

Exposure to developmental risks in three domains (community, economic, and family), and relations between risks and psychosocial well-being, were examined among 918 impoverished Brazilian youth aged 14-19 (M = 15.8 years, 51.9% female) recruited in low-income neighborhoods in one city in Southern Brazil. High levels of developmental risks were reported, with levels and types of risks varying by gender, age, and (to a lesser extent) race. Associations between levels of risks in the various domains and indicators of psychological (e.g., self-esteem, negative emotionality) and behavioral (e.g., substance use) adjustment differed for male and female respondents. Findings build on prior …

Nutrient Cycling In Forage Production Systems, David A. Wedin, Michael P. Russelle

School of Natural Resources: Faculty Publications

In most forage production systems, the nutrients needed for plant growth are provided by microbially mediated breakdown and release of plant-available mineral nutrients from dead plant tissues, livestock excreta, soil organic matter, and geochemically bound mineral forms. Even in fertilized forage systems, determining appropriate fertilizer application rates requires a "systems" approach on the part of the manager (e.g., Di and Cameron, 2000; Rotz et al., 2002). Fertilizer additions are simply one input in the system of inputs, outputs, pools, and fluxes that characterize nutrient cycling in a particular ecosystem.

Livestock On The Cascade-Siskiyou National Monument: A Summary Of Stocking Rates, Utilization, And Management, Paul E. Hosten, Henry Whitridge, Dulcey Schuster, John Alexander

United States Bureau of Land Management: Staff Publications

This paper describes range management related practices to provide a historic and landscape context for studies examining the influence of livestock on objects of biological interest within the Cascade-Siskiyou National Monument. Historic records show livestock numbers increased rapidly following initial settlement by Euro-Americans. Anecdotal data suggests that stocking rates early in the last century were greater than current stocking rates by at least an order of magnitude. Historic unregulated season-long use of the uplands during the spring, summer and fall resulted in severe environmental degradation. Disagreements between livestock operators and the desire of agency personnel to improve the condition of …

Coyotes As Sentinels For Monitoring Bovine Tuberculosis Prevalence In White-Tailed Deer, Todd Atwood, Kurt C. Vercauteren, Thomas Deliberto, Holly Smith, Justin Stevenson

Michigan Bovine Tuberculosis Bibliography and Database

Mycobacterium bovis, the causative agent of bovine tuberculosis (bTB), is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in 5 counties (Alcona, Alpena, Montmorency, Oscoda, and Presque Isle) in the northeastern Lower Peninsula of Michigan, USA. The presence of a wildlife reservoir of tuberculosis in Michigan and the incidence of bTB in cattle (Bos taurus) resulted in Michigan losing its bTB accredited-free status. Subsequent wildlife surveillance programs identified relatively high disease prevalence in coyotes (Canis latrans), generating interest in their potential to serve as a sentinel species to detect bTB prevalence in white-tailed deer. …

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

Grouse have long attracted and fascinated people. Their display behaviour, and particularly their traditional communal mating grounds or "leks,” have inspired poetry and folklore as well as scientific theories on sexual selection and the evolution of mating systems. In many parts of their range, grouse hunting still plays a major role in the culture, economy, and subsistence of local communities.

The 2006-2010 Grouse Action Plan provides an overview to the distribution, status and threats to all 18 grouse species worldwide and identifies the most immediate conservation needs. It is a product of the joint expertise of the Grouse …

Delivering The Science Synthesis: Fuelstools, Anne Black, Susan Perin

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

To facilitate delivery and use of the Fuels Planning: Science Synthesis and Integration Project’s (Project) products, the Project team engaged in a series of technology transfer activities throughout the life of the project. These included bringing land managers into the design and development phase, funding and staffing a specific delivery phase, and conducting an external evaluation to focus future activities. Our plans were informed by concepts central to the diffusion of the innovation theory; in turn, our activities deepened our understanding of the theory and its application to fuels management.

Comparison Of Meat Composition From Offspring Of Cloned And Conventionally Produced Boars, S. C. Walker, R. K. Christenson, R. P. Ruiz, D. E. Reeves, S. L. Pratt, F. Arenivas, N. E. Williams, B. L. Bruner, I. A. Polejaeva

Roman L. Hruska U.S. Meat Animal Research Center: Reports

This study compares the meat composition of the offspring from boars produced by somatic cell nuclear transfer (n = 4) to that of the offspring from conventionally produced boars (n = 3). In total, 89 commercial gilts were artificially inseminated and 61 progressed to term and farrowed. All of the resulting piglets were housed and raised identically under standard commercial settings and slaughtered upon reaching market weight. Loin samples were taken from each slaughtered animal and shipped offsite for meat composition analysis. In total, loin samples from 404 animals (242 from offspring of clones and 162 from controls) …

A Guide To Nestling Development And Aging In Altricial Passerines, Dennis Jonsomjit, Stephanie L. Jones, Thomas Gardali, Geoffrey R. Geupel, Paula J. Gouse

United States Fish and Wildlife Service: Publications

Nestling growth and development studies have been a topic of interest for a greater part of the last century (Sutton 1935, Walkinshaw 1948) and continue to be of interest today. This is not surprising since studies on nestling growth can provide a wealth of biological information that has larger implications for avian management and conservation. Despite this history of studying nestling development, basic information is still limited or absent for many species. Many questions remain unanswered, and contradictory conclusions are often found in the literature (Starck and Ricklefs 1998a). Therefore, much information on aging and development can still be gained …

Evaluation Of Wetlands Created With Effluent From A Swine Concentrated Animal Feeding Operation Using Mallard Sentinels: Implications For Mcmurtrey National Wildlife Refuge, Matthew S. Schwarz, Christina D. Lydick

United States Fish and Wildlife Service: Publications

Previous work by the U.S. Fish and Wildlife Service identified nutrients, elemental contaminants, algal toxins, bacterial pathogens, and hormones as contaminants of concern (COCs) associated with wetlands created from the secondary effluent of a large swine concentrated animal feeding operation. In this follow-up study, COC exposure and effects to waterfowl were evaluated using game farm mallards. Mallards were kept in enclosures built on two created wetlands (treatment sites) and two reference wetlands that are federally managed for waterfowl habitat. Water quality in the created wetland enclosures had higher specific conductivity, BOD, turbidity, pH, and nutrients than reference wetlands. Algal blooms …

Genetic Selection, Sex And Feeding Treatment Affect The Whole-Body Chemical Composition Of Sheep, G. C. Emmans, R. M. Lewis

Department of Animal Science: Faculty Publications

Hypotheses on total body chemical composition were tested using data from 350 Suffolk sheep grown to a wide range of live weights, and fed in a non-limiting way, or with reduced amounts of feed, or ad libitum on feeds of reduced protein content. The sheep were from an experiment where selection used an index designed to increase the lean deposition rate while restricting the fat deposition rate. Ultrasound muscle and fat depths were the only composition measurements in the index. The animals were males and females from a selection (S) line and its unselected control (C). The protein content of …

Regulation Of Hyphal Morphogenesis By Cdc42 And Rac1 Homologues In Aspergillus Nidulans, Aleksandra Virag, Maurice P. Lee, Haoyu Si, Steven D. Harris

Department of Plant Pathology: Faculty Publications

The ability of filamentous fungi to form hyphae requires the establishment and maintenance of a stable polarity axis. Based on studies in yeasts and animals, the GTPases Cdc42 and Rac1 are presumed to play a central role in organizing the morphogenetic machinery to enable axis formation and stabilization. Here, we report that Cdc42 (ModA) and Rac1 (RacA) share an overlapping function required for polarity establishment in Aspergillus nidulans. Nevertheless, Cdc42 appears to have a more important role in hyphal morphogenesis in that it alone is required for the timely formation of lateral branches. In addition, we provide genetic evidence …

Structure And Biosynthesis Of Heat-Stable Antifungal Factor (Hsaf), A Broad-Spectrum Antimycotic With A Novel Mode Of Action, Fengan Yu, Kathia Zaleta-Rivera, Xiangcheng Zhu, Justin Huffman, Jeffrey C. Millet, Steven D. Harris, Gary Yuen, Xing-Cong Li, Liangcheng Du

Department of Plant Pathology: Faculty Publications

A screen for antifungal compounds from Lysobacter enzymogenes strain C3, a bacterial biological control agent of fungal diseases, has previously led to the isolation of heat-stable antifungal factor (HSAF). HSAF exhibits inhibitory activities against a wide range of fungal species and shows a novel mode of antifungal action by disrupting the biosynthesis of a distinct group of sphingolipids. We have now determined the chemical structure of HSAF, which is identical to that of dihydromaltophilin, an antifungal metabolite with a unique macrocyclic lactam system containing a tetramic acid moiety and a 5,5,6-tricyclic skeleton. We have also identified the genetic locus responsible …

Phosphate Imposed Limitations On Biological Reduction And Alteration Of Ferrihydrite, Thomas Borch, Yoko Masue, Ravi K. Kukkadapu, Scott Fendorf

United States Department of Energy: Publications

Biogeochemical transformation (inclusive of dissolution) of iron (hydr)oxides resulting from dissimilatory reduction has a pronounced impact on the fate and transport of nutrients and contaminants in subsurface environments. Despite the reactivity noted for pristine (unreacted) minerals, iron (hydr)oxides within native environments will likely have a different reactivity owing in part to changes in surface composition. Accordingly, here we explore the impact of surface modifications induced by phosphate adsorption on ferrihydrite reduction by Shewanella putrefaciens under static and advective flow conditions. Alterations in surface reactivity induced by phosphate changes the extent, decreasing Fe(III) reduction nearly linearly with increasing P surface coverage, …

Assessment Of Sediment Toxicity During Anaerobic Biodegradation Of Vegetable Oil Using Microtox® And Hyalella Azteca Bioassays, Zhengkai Li, Kenneth Lee, Susan E. Cobanli, Thomas King, Brian A. Wrenn, Kenneth G. Doe, Paula M. Jackman, Albert D. Venosa

United States Environmental Protection Agency: Publications

The potential ecological impacts of anaerobic degradation of vegetable oil on freshwater sediments were investigated. Sediment toxicity was evaluated using two regulatory biotests: the Microtox^® Solid Phase Test and an amphipod (Hyalella azteca) bioassay. The results of the Microtox test showed that the toxicity of the vegetable-oil-contaminated sediments (about 17–33 g oil/kg dry sediments) increased after 2 weeks incubation and then decreased to near background levels after incubation for 8 weeks under anaerobic conditions. The amphipod toxicity bioassay showed that the toxicity of fresh contaminated sediments decreased over time and returned to background levels within 8 weeks. …

Provisioning Strategies Of Antarctic Fur Seals And Chinstrap Penguins Produce Different Responses To Distribution Of Common Prey And Habitat, Taro Ichii, John Bengston, Peter Boveng, Yoshimi Takao, John Jansen, Lisa Hiruki-Raring, Michael Cameron, Hiroshi Okamura, Tomonari Hayashi, Mikio Naganobu

United States Department of Commerce: Staff Publications

Central-place foragers that must return to a breeding site to deliver food to offspring are faced with trade-offs between prey patch quality and distance from the colony. Among colonial animals, pinnipeds and seabirds may have different provisioning strategies, due to differences in their ability to travel and store energy. We compared the foraging areas of lactating Antarctic fur seals and chinstrap penguins breeding at Seal Island, Antarctica, to investigate whether they responded differently to the distribution of their prey (Antarctic krill and myctophid fish) and spatial heterogeneity in their habitat. Dense krill concentrations occurred in the shelf region near the …

Antler Size Of Alaskan Moose Alces Alces Gigas: Effects Of Population Density, Hunter Harvest And Use Of Guides, Jennifer I. Schmidt, Jay M. Ver Hoef, R. Terry Bowyer

United States Department of Commerce: Staff Publications

Moose Alces alces gigas in Alaska, USA, exhibit extreme sexual dimorphism, with adult males possessing large, elaborate antlers. Antler size and conformation are influenced by age, nutrition and genetics, and these bony structures serve to establish social rank and affect mating success. Population density, combined with anthropogenic effects such as harvest, is thought to influence antler size. Antler size increased as densities of moose decreased, ostensibly a density-dependent response related to enhanced nutrition at low densities. The vegetation type where moose were harvested also affected antler size, with the largest-antlered males occupying more open habitats. Hunts with guides occurred in …

Issues Associated With Secondary Analysis Of Population Health Data, Sandra C. Garmon Bibb

Uniformed Services University of the Health Sciences

Analysis of population health data is crucial for the success of population health. Secondary analysis of data contained in publicly available clinical, administrative, and national health survey databases is a cost-effective and scientific method for generating data to support population health. There are several issues associated with secondary analysis of population health data that must be addressed if analyses are to be expedient, economical, and reliable. This article outlines the value of using secondary analysis to generate population health data, discusses issues associated with secondary analysis of population health data, and offers suggestions for addressing these issues.
