Recent Decline Of Lowland Populations Of The Western Gray Squirrel In The Los Angeles Area Of Southern California, Daniel S. Cooper, Alan Muchlinski

Bulletin of the Southern California Academy of Sciences

We provide an overview of the distribution of lowland and otherwise isolated populations of the western gray squirrel (Sciurus griseus) in the Los Angeles area of southern California, an area that has experienced a recent and ongoing invasion by the non-native eastern fox squirrel (Sciurus niger), an urban-adapted species introduced a century ago. Away from its strongholds in the western Santa Monica Mountains, San Gabriel Mountains, and Santa Ana Mountains, the western gray squirrel is resident locally in both the Santa Susana and the Verdugo Mountains, in Griffith Park, in low hills at the eastern periphery of the San Gabriel ...


An Orange Fluorescent Protein Tagging System For Real-Time Pollen Tracking, J. Rice, R. Mundell, R. Millwood, O. Chambers, L. Abercrombie, H. Davies, C. Stewart Dec 2102

An Orange Fluorescent Protein Tagging System For Real-Time Pollen Tracking, J. Rice, R. Mundell, R. Millwood, O. Chambers, L. Abercrombie, H. Davies, C. Stewart

C. Neal Stewart Jr.

Background Monitoring gene flow could be important for future transgenic crops, such as those producing plant-made-pharmaceuticals (PMPs) in open field production. A Nicotiana hybrid (Nicotiana. tabacum × Nicotiana glauca) shows limited male fertility and could be used as a bioconfined PMP platform. Effective assessment of gene flow from these plants is augmented with methods that utilize fluorescent proteins for transgenic pollen identification. Results We report the generation of a pollen tagging system utilizing an orange fluorescent protein to monitor pollen flow and as a visual assessment of transgene zygosity of the parent plant. This system was created to generate a tagged ...


Effect Of External Energy On The Atomic, Crystalline, And Powder Characteristics Of Antimony And Bismuth Powders, Mahendra Kumar Trivedi Sep 2099

Effect Of External Energy On The Atomic, Crystalline, And Powder Characteristics Of Antimony And Bismuth Powders, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

Next to atoms and molecules the powders are the smallest state of matter available in high purities and large quantities. The effect of any external energy on the shape, morphology and structure can thus be studied with relative ease. The present investigation deals with the effect of a non-contact external energy on the powders of antimony and bismuth. The characteristics of powders treated by external energy are compared with the as received powders (control). The average particle sizes, d50 and d99, the sizes below which 99% of the particles are present showed significant increase and decrease indicating that the energy ...

Environmental Res. Bernard Singleton 2016 .Pdf, Joy Semien

Joy Semien

The Deepwater Horizon (DWH) oil spill in the Gulf of Mexico was the largest maritime oil spill in history
resulting in the accumulation of genotoxic substances in the air, soil, and water. This has potential far-
reaching health impacts on cleanup field workers and on the populations living in the contaminated
coastal areas. We have employed portable airborne particulate matter samplers (SKC Biosampler Im-
pinger) and a genetically engineered bacterial reporter system (umu-ChromoTest from EBPI) to de-
termine levels of genotoxicity of air samples collected from highly contaminated areas of coastal
Louisiana including Grand Isle, Port Fourchon, and Elmer's ...

Master's Theses

Critical spawning and feeding habitat was designated for federally threatened, anadromous Gulf Sturgeon (GS) to aid in population recovery. This study examined GS occupancy, habitat use, and movement through critical habitat monitored by the Ship Island (SI) acoustic array during overwintering periods from 2011 to 2015 prior to MsCIP SI restoration. An occupancy index analyzed patterns of spatial and temporal habitat use of both western and eastern population segments (WPS and EPS, respectively) of GS on the SI array. The ends of SI along with the passes and cuts of the island, especially Dog Keys Pass (DKP), were occupied by ...


Psycho-Phenology: Applications Of Ecological Panarchy, Jorge Conesa-Sevilla Phd Nov 2016

Psycho-Phenology: Applications Of Ecological Panarchy, Jorge Conesa-Sevilla Phd

Jorge Conesa-Sevilla PhD


Ecological Panarchy, as described by Gunderson et al, (1995), Holling et al, (2002a), and Holling et al, (2002b), builds up on and extends traditional frameworks for understanding ecological dynamics. It adds to phenology a more realistic emphasis on processes of destruction and organization in addition to the traditional ecological foci on growth and conservation. Their framework adds two additional functions, release and reorganization. Ecological Panarchy is theoretically malleable and can be applied to questions in economics and sociology, to name just two areas, while focusing on problems of resilience and sustainability. Likewise, it is here proposed that this framework might ...


Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David Nielsen, Drew Lyon, Robert Higgins, Gary Hergert, Johnathon Holman, Merle Vigil Oct 2016

Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David Nielsen, Drew Lyon, Robert Higgins, Gary Hergert, Johnathon Holman, Merle Vigil

David C. Nielsen

Crop production systems in the water-limited environment of the semiarid central Great Plains may not have potential to profitably use cover crops because of lowered subsequent wheat (Triticum asestivum L.) yields following the cover crop. Mixtures have reportedly shown less yield-reducing effects on subsequent crops than single-species plantings. This study was conducted to determine winter wheat yields following both mixtures and single-species plantings of spring-planted cover crops. The study was conducted at Akron, CO, and Sidney, NE, during the 2012–2013 and 2013–2014 wheat growing seasons under both rainfed and irrigated conditions. Precipitation storage efficiency before wheat planting, wheat ...

Correlation Analysis Of Enzyme Activities And Deconstruction Of Ammonia-Pretreated Switchgrass By Bacterial-Fungal Communities, Abhiney Jain, H. Sandra Pelle, J. Michael Henson Oct 2016

Correlation Analysis Of Enzyme Activities And Deconstruction Of Ammonia-Pretreated Switchgrass By Bacterial-Fungal Communities, Abhiney Jain, H. Sandra Pelle, J. Michael Henson

Biology Faculty Publications

The mixed microbial communities that occur naturally on lignocellulosic feedstocks can provide feedstock-specific enzyme mixtures to saccharify lignocelluloses. Bacterial-fungal communities were enriched from switchgrass bales to deconstruct ammonia-pretreated switchgrass (DSG). Correlation analysis was carried out to elucidate the relationship between microbial decomposition of DSG by these communities, enzymatic activities produced and enzymatic saccharification of DSG using these enzyme mixtures. Results of the analysis showed that β glucosidase activities and xylosidase activities limited the extent of microbial deconstruction and enzymatic saccharification of DSG. The results also underlined the importance of ligninase activity for the enzymatic saccharification of pretreated lignocellulosic feedstock. The ...


Role Of Hnrnp A1 In The Regulation Of Hdm2 Gene Expression, Heriberto Moran Sep 2016

Role Of Hnrnp A1 In The Regulation Of Hdm2 Gene Expression, Heriberto Moran

All Graduate Works by Year: Dissertations, Theses, and Capstone Projects

hnRNP A1 is one of the most abundant and ubiquitously expressed member of hnRNPs (Heterogenous Nuclear Ribonucleoproteins) family of proteins that play multiple roles in gene expression by participating in major steps in the processing of nascent RNA transcripts 1. It is involved in mRNA biogenesis mechanisms such as the transcription, splicing, stability, export and translation of cellular and viral transcripts. The functions of hnRNP A1 extend to the processing of microRNAs, telomere maintenance and DNA repair 1. Our previous studies have shown that hnRNPA1 had reduced protein level and increased cytoplasmic accumulation in senescent human diploid fibroblasts 2,10 ...

Genotypic Diversity Effects On Biomass Production In Native Perennial Bioenergy Cropping Systems, Geoffrey P. Morris, Zhenbin Hu, Paul P. Grabowski, Justin O. Borevitz, Marie-Anne De Graaff, R. Michael Miller, Julie D. Jastrow

Biology Faculty Publications and Presentations

The perennial grass species that are being developed as biomass feedstock crops harbor extensive genotypic diversity, but the effects of this diversity on biomass production are not well understood. We investigated the effects of genotypic diversity in switchgrass (Panicum virgatum) and big bluestem (Andropogon gerardii) on perennial biomass cropping systems in two experiments conducted over 2008–2014 at a 5.4-ha fertile field site in northeastern Illinois, USA. We varied levels of switchgrass and big bluestem genotypic diversity using various local and nonlocal cultivars – under low or high species diversity, with or without nitrogen inputs – and quantified establishment, biomass yield ...

What Do We Owe Animals As Persons?, Judith Benz-Schwarzburg Aug 2016

What Do We Owe Animals As Persons?, Judith Benz-Schwarzburg

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Rowlands (2016) concentrates strictly on the metaphysical concept of person, but his notion of animal personhood bears a moral dimension (Monsó, 2016). His definition of pre-reflective self-awareness has a focus on sentience and on the lived body of a person as well as on her implicit awareness of her own goals. Interestingly, these also play a key role in animal welfare science, as well as in animal rights theories that value the interests of animals. Thus, Rowlands’s concept shows connectivity with both major fields of animal ethics. His metaphysical arguments might indeed contain a strong answer to the question ...

Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd Aug 2016

Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd

Honors College Capstone Experience/Thesis Projects

The skeletal muscle of obese individuals exhibits a depressed ability to metabolize fats. Exercise training is thought to rescue this dampened ability to metabolize fats; mediated by a coordinated increase in the expression of a network of genes that regulate metabolism and fuel utilization. The purpose of this study is to determine the exercise-induced regulation of metabolically important genes in lean and obese individuals. Muscle biopsies (one pre-exercise/baseline and one immediately post-exercise) were obtained from 4 lean (BF% 24.4 ± 5.5; 23.5 yrs ± 1.9) and 13 obese (BF% 39.7 ± 2.4; 26.1 yrs ± 2 ...

Is Flint Corn Naturally Resistant To Maize Weevil Infestation?, Rashid A. Suleiman, Dennis Williams, Aaron Nissen, Carl J. Bern, Kurt A. Rosentrater

Carl J. Bern

Sitophilus zeamais (maize weevil) is one of the most destructive pests of maize stored in tropical and subtropical regions. This study determined the resistance of flint corn and dent corn to infestation by S. zeamais (Motschulsky), the maize weevil. Improved King Philip hybrid flint corn and Fontanelle 6T-510 hybrid dent corn were used in this experiment. Two temperature conditions (10 °C and 27 °C) and two storage times (15 days and 30 days) were used. Results showed that flint corn was more resistant to insect damage than dent corn at 27 °C and 30 day storage time. After 30 days ...


Grain Test Weight Deception, Carl J. Bern, Thomas J. Brumm Aug 2016

Grain Test Weight Deception, Carl J. Bern, Thomas J. Brumm

Carl J. Bern

Test weight is used as an indicator of general grain quality and is a measure of grain bulk density. Test weight, but not overall grain weight, normally increases during drying. Erroneous calculations using test weights can incorrectly infer that drying systems that increase test weight also increase the number of bushels that can be sold. This bulletin explains the use of test weight in the grain industry, how it can be used to determine grain value, and why some calculations involving test weight can be deceptive.


Hermetic On-Farm Storage For Maize Weevil Control In East Africa, Ali Yakubu, Carl J. Bern, Joel R. Coats, Theodore B. Bailey Aug 2016

Hermetic On-Farm Storage For Maize Weevil Control In East Africa, Ali Yakubu, Carl J. Bern, Joel R. Coats, Theodore B. Bailey

Carl J. Bern

Maize (Zea mays L.) consumption makes up over half of daily caloric intake of persons in East Africa and adequate supply is necessary for food security for subsistence farmers, as well as for domestic stability. Hermetic post-harvest maize storage is an attractive non-chemical control strategy for maize weevil,Sitophilus zeamais (Motsch.), which is the principal cause of insect damage to stored maize grain. Laboratory experiments were conducted on instrumented hermetic and non-hermetic containers to measure effects of temperature (10 vs. 27°C) and maize moistures (6.3 to 16%) on maize weevil biology and mortality rate, and to quantify weevil ...


Friction Coefficients For Dried Distillers Grains On Eight Structural Surfaces, Guevara C. Nyendu, Spencer Pflum, Paul Schumacher, Carl J. Bern, Thomas J. Brumm Aug 2016

Friction Coefficients For Dried Distillers Grains On Eight Structural Surfaces, Guevara C. Nyendu, Spencer Pflum, Paul Schumacher, Carl J. Bern, Thomas J. Brumm

Carl J. Bern

Static and dynamic coefficients of friction on structural surfaces play important roles in the power requirements and material selection for equipment used in handling and storing agricultural commodities. However, friction data on dried distillers grains with solubles (DDGS) is limited. Further, lack of a standardized method for determining friction coefficient on grain handling materials presents a challenge. This article describes studies carried out to determine the static coefficient of friction (µs) and dynamic coefficient of friction (µd) for corn DDGS at 10%, 8.2%, and 6.5% moisture content (all moistures are % wet basis) on eight structural surfaces: High-Density Polyethylene ...


Evaluation Of Hermetic Maize Storage For Smallholder Farmers, Denis Bbosa, Thomas J. Brumm, Carl J. Bern, Kurt A. Rosentrater Aug 2016

Evaluation Of Hermetic Maize Storage For Smallholder Farmers, Denis Bbosa, Thomas J. Brumm, Carl J. Bern, Kurt A. Rosentrater

Carl J. Bern

Maize is an important crop for many smallholder farmers in the world. Maize weevils (Sitophilus zeamais) cause a significant loss in quality and quantity during maize storage in tropical regions. Hermetic storage of maize has been shown to be effective in controlling maize weevils in laboratory settings. The objective of this research was to test the effectiveness of hermetic storage containers that could be used by smallholder farmers. Six 208-L (55-gallon) steel barrels were filled with 170 kg (375 lb) of maize with initial weevil populations of 25 live weevils/kg of maize (11 live weevils/lb). The barrels were ...
