Comparison Of An Endangered Species’ Seed Bank Before And After Ungulate Removal, Melanie K. Phillips, Kathryn Mceachern

STAR Program Research Presentations

The purpose of this study was to assess the impact of the removal of ungulates on the soil seed bank of the endemic Santa Rosa Island manzanita (Arctostaphylos confertiflora). A. confertiflora was trampled and browsed by non-native ungulates between the years 1850 and 2011 which reduced its ability to produce seeds.This species is an obligate seeder, meaning that sprouting from seeds in the soil is its only method of reproduction. Due in part to the lack of its soil seed bank, this species was federally listed as endangered by the US Fish and Wildlife Service in 1997. In order to …

Reversible Motion In A Contact Line, Audrey Profeta, Esmeralda Orozco, Juan A. Ortiz Salazar, Dani Medina, Nathan C. Keim

STAR Program Research Presentations

When a body of liquid sits on a surface, an irregular border between the wet and dry regions of the surface exists, called the contact line. Driving this contact line back and forth repeatedly can change its shape.We use a syringe pump to cyclically infuse and withdraw a predetermined volume of water, and take photos of the contact line after each cycle. Comparing these images to each other determines if the contact line is returning to the same shape. We find that below a critical value of infused volume, after many cycles the contact line reaches a steady state in …

This sample is analyzed for consistency with a relation between the temporal decay and spectral indexes predicted by the Fireball model of GRB Emission. …

Women With A Cause: Art, Representation, And Feminist Progress In Eighteenth-Century France, Darby Marie Leahy

Master's Theses

Throughout the eighteenth century the Age of Enlightenment transformed public discourse across Western Europe. In France, the salons of Paris became the primary institutions of Enlightenment thought. Hosted by women, the salons possessed a unique atmosphere in which men and women were regarded as intellectual equals. My thesis focuses on the role the female hostesses, salonnières, had in initiating French movements for gender equality that continued with great momentum throughout the French Revolution. By using popular artwork, literature, and memoirs I show how the efforts of French women to achieve gender equality helped give early rise to feminism.

An Assessment Of The Greatest Impacts On Distribution Uniformity For Drip And Micro Irrigation, Brooke Ashley Worden

Master's Theses

Using the Cal Poly Irrigation Training and Research Centers (ITRC) drip/micro evaluation program, global, or system, DU_lq is computed by combining the component DU_lq values of: pressure variation, uneven spacing between emitters, unequal drainage and “other” causes. “Other” causes include plugging, wear and manufacturing coefficient. The program also computes what percentage of the non-uniformity is due to each component. Burt (2004) showed that over 95% of the non-uniformity is due to “Other” causes and pressure differences. This thesis looks at what specifically in those components is driving the non-uniformity by analyzing various equipment and field practices and their …
