I attended the Students Works Symposium paper session related to the natural sciences. Taylor Jones and Alexis Ritzer talked about their project working with Armadillidium vulgare, also known as the roly poly. There is a bacterium called a Wolbachia that commonly infects the systems of the A. vulgare. This bacterium can only be based from a female to her offspring, and as a result the Wolbachia have evolved to feminize the male A. vulgares they infect. This increases their chance of being passed on (surviving). In some populations of A. vulgare, this feminization has caused a sex ratio skew, with more females than males. When Jones and Ritzer collected samples of the isopods, they found skewed sex ratios in three of the samples, though they did not find any Wolbachia. I find this project extremely interesting; the fact that this bacteria and isopod have coevolved for so long that the bacteria has actually changed the distribution of sexes in certain populations is amazing.
Anna Frankel talked about her work at Sea Turtle, Inc. in South Padre Island. She discussed their philosophy, which is summed up in a cause-and-effect cycle that included education, interest in refuges, desire to conserve a species, and generating revenue. It is by using this cycle—focusing on educating—that they generate an income for their own non-profit organization and are able to donate to others.
Colin Kyle presented the project he’s been doing with Apple Snails. He did three different experiments examining the egg-laying preferences of them. He tested whether or not the snails prefer natural or artificial material, elephant ear leaves or other plant leaves, cylindrical or rectangular objects, and tall or short objects. He found that the Apple Snails preferred natural material, elephant ear leaves, cylindrical objects and had no preference for short or tall objects.
At the poster session, I spent the majority of my time looking at Nick Parker’s poster presentation about torture. I thought this was interesting, especially since we discussed this issue one day in class. He stated that while it is virtually impossible to monitor torture, he does not think that the United States should condone torture. A lot of his arguments are issues that we talked about during our discussions, such as the fact that torture has always occurred and the fact that implementing anti-torture laws would be extremely difficult.
I was somewhat intimidated by the fact that I will have to make a presentation similar to these in just two years. The projects seemed to be at such a high level and I’m not so sure I will be there by my senior year. Overall though, I was very impressed by the students’ presentations.
