Recent Decline Of Lowland Populations Of The Western Gray Squirrel In The Los Angeles Area Of Southern California, Daniel S. Cooper, Alan Muchlinski Jul 2105

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 ...


Molecular Biology Of A Surface-Exposed Protein Family Of Bartonella Bacilliformis, Hannah Fay Jan 2017

Molecular Biology Of A Surface-Exposed Protein Family Of Bartonella Bacilliformis, Hannah Fay

Undergraduate Theses and Professional Papers

Bartonella bacilliformis is a gram negative alpha-proteobacterium native to the Andes of South America. Bartonella causes Carrion’s disease, a potentially life threatening disease transmitted by the sand fly. It has a mortality rate of 88% when untreated and 10% when treated. Diagnostics and control measures for the disease are underdeveloped and no vaccine is available. Recent outbreaks indicate that the range of the pathogen is increasing with nearly 1.7 million people in western South America at risk. Little is known about the epidemiology and pathogenesis of B. bacilliformis. Recent research done by UC San Diego found a paralogous ...

Principles Of Space Anthropology: Establishing A Science Of Human Space Settlement, Cameron Smith Dec 2016

Principles Of Space Anthropology: Establishing A Science Of Human Space Settlement, Cameron Smith

Cameron Smith

Human space settlement will be the extension of human adaptation from terrestrial to extraterrestrial (off-Earth) environments. Space settlement should therefore be planned and carried out with a thorough understanding of human adaptation—both biological and culturalwhich is best known today to the field of anthropology. In this book I outline the principles of an evolutionary, adaptation-based anthropology useful to making a success of the goal of permanent human space settlement.

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 ...


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 ...

Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam Aug 2016

Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam

Master's Theses

In recent years, the Mississippi Department of Marine Resources (DMR) has made a concerted effort to enhance its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high profile breakwater and low profile submerged structures. This study compared the benthic biota associated with oyster shell and cement rubble substrates among four artificial reefs representing high and low profile structures in summer 2011. Colonized benthic biota were quantified ...
