Porcellio laevis Preference of Warm Colored Light over Cooler Colored Light Morgan Graham, Jamie Wann, Rylie Cook Summary Porcellio laevis, sow bug, is a terrestrial isopod that has evolved different behaviors to better survive and reproduce. Porcellio laevis normally prefer environments that are moist, humid, and dark. In this experiment, I tested the effects of warm and cool colored light on Porcellio laevis. I performed different treatments comprised of either red light, blue light, and the control of having no film covering the overhead lamp. The results show that the number of Porcellio laevis in the red chamber always have more in it than any of the other chambers. The Porcellio laevis did prefer the blue light, cool colored, over the control, but the trend was significantly less than the red colored light trend. This determined that Porcellio laevis prefer to be in warm colored light. Introduction Animal behavior is defined as the study of how organisms respond to different stimuli within the environment. Scientists who study the behaviors of animals are known as ethologists. Ethograms were designed to allow biologists who study animal behavior to understand why the animal does certain things or how they are able to evolve to better fit within the environment. The Tinbergen’s model is a framework for the study of animal behavior. According to the model, the cause of the animal behavior, the change of the behavior throughout their life, the evolution of the behavior, and how the specific behavior could improve the animal’s chance at survival and

    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.
