with pink and purple flowers often demonstrate a fitness advantage in more arid habitat (Schemske and Bierzychudek 2001, 2007, Carlson and Holsinger 2015, Warren and Mackenzie 2001). Based on these prior findings, we gathered data on elevation, longitude and average annual precipitation to determine whether these factors influence the distribution of flower color in Erythranthe discolor .

In order to test our hypothesis, we visited and recorded GPS coordinates for sixteen populations in the Piute Mountains, Kern County, California. We also Surveyed the sixteen populations by counting each individual and recording flower color. We measured plant height, calyx tube length, flower length, and flower width, then Collected voucher specimens and a maternal line seed collection made up of twenty individuals of each color morph. To analyze the data collected in the field we Gathered precipitation data from longitude and latitude coordinates using PRISM normals (baseline datasets describing average monthly and annual conditions over the most recent three full decades currently: 1981-2010; ) , and retrieved elevation data from the Montana State University Environmental Statistics Group which utilizes a digital elevation model (DEM) based on latitude and longitude coordinates. Finally we mapped the populations with ArcGIS and Google Earth.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
