During my first semester with the Sustainability Studies Earthworm Ecotoxicology lab, back in January 2012, I had seven brave students working with me. We wanted to examine the effect of acid rain on earthworm health, so we designed and ran the research—and made a lot of mistakes. Some of them were pretty funny. As a primate behavioral ecologist, I didn’t know a lot about earthworms. Who knew that earthworms wouldn’t stay in the containers you put them in? Who knew that fungus gnats from earthworm soils could take over a greenhouse? Well, we know those things now!

With more than thirty students working in the lab each semester, we’ve conducted handfuls of important research. We’ve looked at the effects of substances like fertilizer, Ortho Weed B Gon and Roundup on earthworm health. We’ve submitted a total of six posters to URECA. We’ve helped one student conduct her research for the Honors College, and we’ve participated in the Earthstock Keynote address.

The earthworm students work in groups, run by team leaders. They come to me with ideas, we work though the logistics and hone their hypotheses, and then those students organize the manual labor, data collection and write up. In keeping with that spirit, my current group of students, who are divided into two smaller sub-groups, describe their current research below:

The Cadmium Project

Students sifting soil for use in an experiment.

The goal of our experiment is to determine how long it will take to breed cadmium-resistant earthworms. We predict that it will take more than 4 months for the cadmium resistant earthworm to sustain a fertility rate that is comparable to those of normal earthworms. Cadmium is a known pollutant that has negative effects on the fertility of earthworms. This substance enters the environment through sewage waste, as well as its use in manures and pesticides. This chemical is known to affect the earthworms by markedly decreasing the amount of cocoons that can be produced by earthworms per reproductive cycle. To test our hypothesis, we are placing earthworms in soil that has had a cadmium solution applied to it in varying amounts. The soil will be tested over a period of 6 months for microbe respiration. Additionally, we will be determining the resulting earthworm mortality and biomass. This experiment has given us the opportunity to raise awareness to others about the potential dangers of using these particular chemicals.

The Roundup Project

At the Life Sciences Greenhouse, we’re testing the effect of Roundup on soil microbial respiration and earthworm mortality, the supervision of Dr. Pochron and with the assistance of Michael Axelrod and John Klumpp. This project is an interdepartmental collaboration between Sustainability, Biology and Chemistry. We want to see if Roundup, a popular household herbicide, affects soil microbial consortium and worm mortality. Since earthworm presence indicates healthy soil activity, we predict Roundup will negatively affect soil microbial respiration and increase worm mortality. Results from this study will help elucidate the effects of anthropogenic herbicide use on soil ecosystems. Working in the lab, we learn to independently conduct experiments through hands-on experience.

From October 29 to November 5, 2014, my colleagues Professor Melinda Levin (University of North Texas) and Filip Celdander (University of Texas, Dallas), and I traveled to Cuba under a cultural visa given to us by the Cuban Ministry of Culture to collaborate with Artes Escenicas, Cuba’s leading performing arts organization, to film performing arts groups in Cuba doing environmental outreach.

Over the week, we filmed Teatro Cabotin in Sancti Spiritus, Teatro de los Elementos in Cumanayagua, La Fortaleza in Juragua, and Teatro de Colaboracion con el Medio Ambiente in Romerillo-Havana. The goal of this collaboration was to explore the use of performing arts as a form of outreach and education. We stayed in small Cuban communities, living with the locals. One community, Teatro de los Elemntos, has an organic farm and the locals there live sustainably. There and elsewhere, we noted the specific community issues locals are addressing and in our filmmaking emphasized their creative responses to problems/challenges with the environment.

Our documentary work is meant to help us better understand the creative process, the daily lives of the artists and community members, and the connection between art, community and positive social change. My colleagues and I gathered over twenty-five hours of film footage of performances and interviews as well as thousands of photos of locations and performances. The products of our research will include published essays and interviews, short documentary films and eventually a longer work on Cuban arts and the environment.

Artes Escenicas has already invited our group to return and collaborate more extensively in 2015. This year we will work more intensely with Teatro Cabotin and Teatro de los Elementos, and will also travel to Las Tunas to film Teatro Tuyo and its latest theatrical work, Gris. The director of Teatro Tuyo, Ernesto Parra, explains that the purpose of Gris is to raise awareness of the importance of environmental protection.
