Biology Major Received Drinko Grant to Present Honors Research

Michelle Johnston, a Westminster College senior biology major, received a travel/presentation grant from Westminster's Drinko Center for Excellence in Teaching and Learning to present her honors research at the 30th annual Undergraduate Biology Symposium for Western Pennsylvania April 18 at Waynesburg University.

Johnston is a daughter of Ray and Kimberly Johnson of Beaver Falls and a graduate of Blackhawk High School.

Johnston's research, "Effects of pH and Glyphosate on Rana pipiens Development and Survival," was advised by Dr. Shahroukh Mistry, Westminster associate professor of biology.

Amphibian species have been declining worldwide over the last few decades, resulting in many species being declared threatened or endangered. Scientists have developed various hypotheses regarding the cause of the declines-including herbicides, pesticides, UV radiation, diseases, and climate change-yet, even after many experiments, the causes remain an enigma, according to Mistry.

"Michelle's honors research explores one specific aspect of amphibian decline by examining the effects of glyphosate and the acidity of the water on the development and survival of leopard frog tadpoles," Mistry said. "Glyphosate, the major ingredient in Roundup, ends up in water bodies through runoff and is possibly one of the herbicides that affects amphibians. This study puts us one step closer to ultimately deciphering amphibian declines and formulating strategies to minimize the loss and prevent species extinction."

The Drinko Center for Excellence in Teaching and Learning was created to enrich undergraduate education at Westminster through advancing world-class teaching as well as by participating in collaborations that address community and regional needs including strengthening K-12 education. The Undergraduate Research Initiative provides funding for students to conduct research and to present their research at regional and national conferences.
