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

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

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 ...

Effects Of Slope Upon Hind Limb Kinematics In Chukar Partridge (Alectoris Chukar), Anna T. Kenney

Undergraduate Theses and Professional Papers

Ground dwelling birds must scale all kinds of complex terrain in order to survive in their natural environments. For instance, Alectoris chukar live on steep hillsides with slopes of up to 60° or 172.3% slope. We undertook the present study to improve understanding of how birds successfully traverse such complex terrain. Using a high speed camera, we analyzed the hind limb kinematics of chukars during normal locomotion on a 10° and 35° incline, decline, and level slope. We compared the data collected from the video recordings, which we had used to identify and digitize the bony landmarks, between all ...

Phr: Patient Health Record, Quinn Nelson

Theses/Capstones/Creative Projects

The rapid development of information technology systems has expanded into multiple disciplines and results in systems that are limited by initial design and implementation: the Healthcare Information Technology (HIT) space is no different. The introduction of the Electronic Health Record (EHR) system has changed the way healthcare operates. Initial designs of these systems were focused on serving the needs of insurance companies and healthcare billing departments. Research shows that the design of EHR systems negatively impact provider-patient interactions and the care they receive. This capstone project capitalizes on the collaboration efforts between UNO and UNMC – by joining a research group ...

The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen

Articles

Although both local processes (photosynthesis, respiration, grazing, and settling), and transport processes (advective transport and diffusive transport) significantly affect local phytoplankton dynamics, it is difficult to separate their contributions and to investigate the relative importance of each process to the local variability of phytoplankton biomass over different timescales. A method of using the transport rate is introduced to quantify the contribution of transport processes. By combining the time-varying transport rate and high-frequency observed chlorophyll a data, we can explicitly examine the impact of local and transport processes on phytoplankton biomass over a range of timescales from hourly to annually. For ...

Exploring Multiple Operating Scenarios To Identify Low-Cost, High Nitrate Removal Strategies For Electrically-Stimulated Woodchip Bioreactors, Ji-Yeow Law, Michelle L. Soupir, D. Raj Raman, Thomas Moorman

Agricultural and Biosystems Engineering Publications

Woodchip bioreactors are recognized as an effective best management practice in the Iowa Nutrient Reduction Strategy. This edge-of-field practice intercepts and removes NO3-N, thereby reducing the NO3-N concentration in tile drainage before being discharged into surface water. Actual NO3-N load reductions realized by woodchip bioreactors are impacted by bioreactor size, hydraulic retention time (HRT), and denitrification efficiency. A typical woodchip bioreactor in Iowa may have 0.07% bioreactor area with respect to treatment area, 4–8 h HRT, and 43% mean denitrification efficiency. Here, we explored the potential of using electrically stimulated woodchip bioreactors to achieve greater NO3-N removal, and ...

Understanding Plant Secondary Metabolites; Above And Below Ground, Andrea K. Clemensen

All Graduate Theses and Dissertations

Plants naturally produce primary and secondary metabolites. Primary metabolites are directly involved with plant growth and metabolic function. Plant secondary metabolites (PSM) were once thought of as metabolic waste products, and more recently viewed as toxins to herbivores. However, ongoing research shows that PSM are beneficial to herbivores at low doses, and PSM aid plants by attracting pollinators, recovering from injury, protecting from ultraviolet radiation, increasing drought tolerance, and aid in defense against pathogens, diseases, and herbivores. Plant secondary metabolites also influence soil nutrient cycling, and can increase the sustainability of agroecosystems. Endophyte-infected tall fescue (Festuca arundinacea Schreb.) , which contains ...

Using Anthropogenic Risks To Inform Salmonid Conservation At The Landscape Scale, Andrew W. Witt

All Graduate Theses and Dissertations

The expansion and industrialization of humanity has caused many unforeseen consequences to the natural world. Due to the importance of freshwater for people, rivers have been particularly altered to meet human needs, often at the expense of the natural world. Supplying water for farms, industries, and cities has reshaped the natural state of rivers by altering river paths, chemistry, and species compositions. These changes have harmed many species that prospered before widespread human alterations, including the native trout and salmon of western North America. As human populations continue to grow, new threats will surface for rivers, and the trout and ...

Comparative Pollination Efficacies Of Bees On Raspberry And The Management Of Osmia Lignaria For Late Blooming Crops, Corey J. Andrikopoulos

All Graduate Theses and Dissertations

Unlike other rosaceous fruit crops such as apple and cherry, commercial raspberry cultivars are largely self-fertile and can set fruit in the absence of pollinators. However, their floral morphology often prevents complete self-pollaintion. Incomplete pollination yields unmarketable small or crumbly fruits. Insect visitation is therefore essential to maximizing raspberry yield. Honey bees are typically used to pollinate commercial raspberry; however, escalating prices for hive rentals coupled with increasing acreage encourage evaluation of other manageable pollinators. Bumble bees (Bombus spp.) and several mason bees (Osmia spp.) are promising raspberry pollinators. Five bee species were evaluated and compared for their single-visit pollination ...

The objective of this study was to determine the dry matter yield and quality effects of corn hybrids grown in different plant densities and row widths in the Intermountain West. Field experiments were conducted under irrigation in 2015 and 2016 at locations near North Logan, Utah and Jerome, Idaho. The experimental design was a randomized complete block ...

Utilizing Legumes To Improve Production And Nutritive Value Of Intermountain West Pastures, Jacob T. Briscoe

All Graduate Theses and Dissertations

Pastures in the Intermountain Western United States mainly consist of cool-season grasses which lack production without supplemental nitrogen. Legumes provide nitrogen at reduced cost compared to nitrogen fertilizer. There is a need for proven methods of inter-seeding legumes into existing cool-season grass pastures as well as knowledge of how animals prefer legumes to grasses and how the nutritive value of forages change throughout the growing season. This research provides a resource for effective integration of legumes into pastures of the Intermountain West. Alfalfa, birdsfoot trefoil, and cicer milkvetch were inter-seeded into existing cool-season grass pastures following pretreatments of light tillage ...

Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Noah G. Perlut, Patricia G. Parker, Rosalind B. Renfrew, Maricruz Jaramillo

Environmental Studies Faculty Publications

Bobolinks (Dolichonyx oryzivorus) migrate from their breeding grounds in North America to their wintering grounds in South America during the fall each year. A small number of Bobolinks stop temporarily in Galapagos, and potentially carry parasites. On the North American breeding grounds, Bobolinks carry a least two of the four Plasmodium lineages recently detected in resident Galapagos birds. We hypothesized that Bobolinks carried these parasites to Galapagos, where they were bitten by mosquitoes that then transmitted the parasites to resident birds. The haemosporidian parasite community in 44% of the Bobolinks we captured was consistent with those on their breeding grounds ...

The Immediate Influence Of Whole Body Vibration On Proprioceptive Precision, Sean Madill

All Graduate Plan B and other Reports

As our bodies are exposed to whole-body vibration inertial and strain sensitive sensory receptors throughout our body are activated. The information relayed from these receptors to the central nervous system and brain is used to analyze our environment and coordinate movement. The aim of this study was to investigate whether extended duration whole-body vibration influences sensory adaptation and coordinated movement, specifically our joint position acuity immediately following vibration exposure. Twenty-five adults completed a between ankle joint matching task before and immediately following a 20-minute whole-body vibration session and a control session of 20 minutes of standing near, but not on ...

Phenotypic Association Between Lactose And Other Milk Components In Western Us Dairy Herds And Japan, Takuji Asami

All Graduate Theses and Dissertations

Lactose in milk has relatively low variation regardless of season, breed, or country. The study of lactose concentration and correlation among other milk components is limited. Furthermore, dairy farmers have limited access to the lactose data and are not familiar with it. This study was conducted to: 1) investigate the phenotypic correlation between lactose and other milk components; and 2) determine the importance of lactose for dairy herds.

Monthly DHIA records from Utah (DHIA), Dairy Herd Performance Test (DHTP) records from Ibaraki, Japan, and California herd average data (CHAD) covering 27 states were used to analyze the relationships between milk ...

A Rationally Engineered Capsid Variant Of Aav9 For Systemic Cns-Directed And Peripheral Tissue-Detargeted Gene Delivery In Neonates, Dan Wang, Shaoyong Li, Dominic J. Gessler, Jun Xie, Li Zhong, Jia Li, Karen Tran, Kim Van Vliet, Lingzhi Ren, Qin Su, Ran He, Jason E. Goetzmann, Terence R. Flotte, Mavis Agbandje-Mckenna, Guangping Gao

Open Access Articles

Adeno-associated virus (AAV) has provided the gene therapy field with the most powerful in vivo gene delivery vector to realize safe, efficacious, and sustainable therapeutic gene expression. Because many clinically relevant properties of AAV-based vectors are governed by the capsid, much research effort has been devoted to the development of AAV capsids for desired features. Here, we combine AAV capsid discovery from nature and rational engineering to report an AAV9 capsid variant, designated as AAV9.HR, which retains AAV9's capability to traverse the blood-brain barrier and transduce neurons. This variant shows reduced transduction in peripheral tissues when delivered through ...

Soil Conservation Efforts Affecting And Implementations To Help Tree Growth In Iceland, Justin Lawlor

Student Works

The purpose of this research was to understand and project the opinions of the public in Iceland on soil conservation and current efforts. The issue of soil erosion dates back to settlement around 1,100 years ago. The loss of vegetation from deforestation and grazing exposes the land to the effects of wind, water, and other devastating elements, leading it to erode away. The Soil Conservation Service of Iceland (SCSI) was developed to combat this issue over 100 years ago with efforts including planting trees, promoting safe farming practices, and replenishing the land. Interviews were conducted with various individuals, including ...
