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 ...


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 ...

Effects Of Slope Upon Hind Limb Kinematics In Chukar Partridge (Alectoris Chukar), Anna T. Kenney Jan 2020

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 ...


Real-Time Stealth Intervention For Motor Learning Using Player Flow-State, Ramin Tadayon, Ashish Amresh, Troy Mcdaniel, Sethuraman Panchanathan Jun 2019

Real-Time Stealth Intervention For Motor Learning Using Player Flow-State, Ramin Tadayon, Ashish Amresh, Troy Mcdaniel, Sethuraman Panchanathan

Ashish Amresh

We present a novel approach to real-time adaptation in serious games for at-home motor learning. Our approach assesses and responds to the “flow-state” of players by tracking and classifying facial emotions in real-time using the Kinect camera. Three different approaches for stealth assessment and adaptation using performance and flow-state data are defined, along with a case-study evaluation of these approaches based on their effectiveness at maintaining positive affective interaction in a subject.


Messy Eating, Samantha King, R Scott Carey, Isabel Macquarie, Victoria Millious, Elaine Power Jun 2019

Messy Eating, Samantha King, R Scott Carey, Isabel Macquarie, Victoria Millious, Elaine Power

Environmental Studies

Literature on the ethics and politics of food and that on animal-human relationships have infrequently converged. Representing an initial step towards bridging this divide, Messy Eating features interviews with thirteen prominent and emerging scholars about the connections between their academic work and their approach to consuming animals as food. The collection explores how authors working across a range of perspectives—postcolonial, Indigenous, Black, queer, trans, feminist, disability, poststructuralist, posthumanist, and multispecies—weave their theoretical and political orientations with daily, intimate, and visceral practices of food consumption, preparation, and ingestion.

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom May 2019

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U ...


Impacts Of Cattle Grazing As A Tool To Control Phragmites Australis In Wetlands On Nitrogen, Phosphorus, And Carbon, Brittany L. Duncan May 2019

Impacts Of Cattle Grazing As A Tool To Control Phragmites Australis In Wetlands On Nitrogen, Phosphorus, And Carbon, Brittany L. Duncan

All Graduate Theses and Dissertations

Phragmites australis is a plant that is causing problems in wetlands by outcompeting native plants that provide food and shelter for millions of migratory birds. Currently, managers try to control Phragmites australis by spraying herbicide, burning, and mowing, but these methods are costly, time consuming, and have low levels of success. Adding grazing as a tool to control Phragmites australis provides a cheap and low labor alternative. However, there are many concerns regarding if grazing will cause nutrient loading in our wetlands that will decrease water quality and alter beneficial functions of wetlands.

To better understand the effects of grazing ...


Reoccupy Earth [Table Of Contents], David Wood Apr 2019

Reoccupy Earth [Table Of Contents], David Wood

Philosophy

Habit rules our lives. And yet climate change and the catastrophic future it portends, makes it clear that we cannot go on like this.

Our habits are integral to narratives of the good life, to social norms and expectations, as well as to economic reality. Such shared shapes are vital. Yet while many of our individual habits seem perfectly reasonable, when aggregated together they spell disaster. Beyond consumerism, other forms of life and patterns of dwelling are clearly possible. But how can we get there from here?

Philosophy is about emancipation—from illusions, myths, and oppression. In Reoccupy Earth, the ...

Vietnam Food Culture, Candace Nelson Apr 2019

Vietnam Food Culture, Candace Nelson

All Student-Created Educational Resources

The food scene in Vietnam is social and lively. The demand for fresh meat, seafood, and produce has open-air markets open twice per day. The demand for freshness also limits opportunities to enforce food safety regulations. Vietnam has one of the highest rates of vegetable consumption in the world. Rice is also consumed in large portions, but malnourishment rates are high. Common deficiencies include vitamin A, iron, iodine, and zinc. Honoring the dead through food is a common practice.


Changes In Spring Arrival Times: Climate Change And The Phenology Of Spring Bird Migration, Aaron Svedlow Apr 2019

Changes In Spring Arrival Times: Climate Change And The Phenology Of Spring Bird Migration, Aaron Svedlow

Student Scholarship

Climate change and weather affect the phenology of bird migration; however, specific climatological factors associated with these observed effects have only recently been described. The relationship between local, regional, and global climate patterns and avian migration are increasingly important to understand due to the widespread, and potentially negative, implications (such as reduced fecundity) of rapid human induced climate change on bird populations. Migratory birds are under selective pressure to arrive at breeding areas at the optimal time to set up nesting territories and exploit seasonally abundant food resources, and because climate change has the potential to occur more rapidly than ...


Exterranean [Table Of Contents], Phillip John Usher Mar 2019

Exterranean [Table Of Contents], Phillip John Usher

Literature

“For anyone who might be suffering from Anthropocene fatigue, this is a book to jolt you from your slumbers. What happens to the globe when we shift attention from the outward projection of emissions to extraction ? The Earth we thought we knew, and were already mourning, takes on a stunning new critical light.”—Claire Colebrook, Pennsylvania State University

Exterranean concerns the extraction of stuff from the Earth, a process in which matter goes from being sub- to exterranean. By bringing a rich archive of nonmodern texts and images from across Europe, into conversation with the contemporary work of Bruno Latour ...


Stability Analysis Of Kernel Quality Traits In Exotic-Derived Doubled Haploid Maize Lines, Adam Vanous, Candice Gardner, Michael Blanco, Adam Martin-Schwarze, Jinyu Wang, Xianran Li, Alexander E. Lipka, Sherry Flint-Garcia, Martin Bohn, Jode Edwards, Thomas Lubberstedt Mar 2019

Stability Analysis Of Kernel Quality Traits In Exotic-Derived Doubled Haploid Maize Lines, Adam Vanous, Candice Gardner, Michael Blanco, Adam Martin-Schwarze, Jinyu Wang, Xianran Li, Alexander E. Lipka, Sherry Flint-Garcia, Martin Bohn, Jode Edwards, Thomas Lubberstedt

Agronomy Publications

Variation in kernel composition across maize (Zea mays L.) germplasm is affected by a combination of the plant’s genotype, the environment in which it is grown, and the interaction between these two elements. Adapting exotic germplasm to the US Corn Belt is highly dependent on the plant’s genotype, the environment where it is grown, and the interaction between these components. Phenotypic plasticity is ill-defined when specific exotic germplasm is moved over large latitudinal distances and for the adapted variants being created. Reduced plasticity (or stability) is desired for the adapted variants, as it allows for a more rapid ...

Environmental Science and Management Faculty Publications and Presentations

Dramatic growth in herbicide-resistant (HR) weeds in the United States threatens farm profitability and may undercut environmentally beneficial farming practices. When HR weeds move across farm boundaries due to ecological processes or human action, a common pool resource challenge emerges, requiring farmer cooperation to manage such weeds effectively. We investigate the scope for cooperative management using responses to a national survey on HR weed issues to test a recursive model of three preconditions for collective action: (1) concern about HR weeds migrating from nearby lands; (2) communication with neighbors about HR weeds; and (3) belief that cooperation is necessary for ...


Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2018, Troy D. Tuckey, Mary C. Fabrizio Mar 2019

Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2018, Troy D. Tuckey, Mary C. Fabrizio

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193 ...


Evaluation Of Two Implants For Steers On Early-Intensively Grazed Tallgrass Native Range, J. K. Farney, M. E. Corrigan Feb 2019

Evaluation Of Two Implants For Steers On Early-Intensively Grazed Tallgrass Native Range, J. K. Farney, M. E. Corrigan

Kansas Agricultural Experiment Station Research Reports

Objective: To evaluate the effect of two implants that have different lengths of effective use on stocker cattle gains within an intensive early double-stocked native tallgrass prairie grazing system.

Study Description: Stocker steers (n = 281) were implanted with Revalor-G (Merck Animal Health, Madison, NJ) or Synovex One Grass (Zoetis, Inc., Kalamazoo, MI) and grazed on tallgrass native range for 90 days during the summer. The steers were individually weighed, after an overnight shrink, on the day of implanting, at midpoint of grazing, and the end of the grazing period. Total gains and average daily gain were evaluated.
