Manisha Kumar participated in Celebration of Learning

2012 May 7

More than 75 Augustana students from all academic areas shared their advanced research projects on Saturday, May 5, at the Celebration of Learning. This on-campus research symposium annually gives students an opportunity to show off their academic accomplishments to their families and the Augustana community.

Among the students involved:

Manisha Kumar, a junior from Davenport, Iowa, majoring in biology and pre-medicine. The research was titled Characterizing the Cold-Conditioning Response in a Vertebrate Ectotherm. Ectothermic animals rely on seasonal increases in cold hardiness to survive a thermally variable environment, but a more rapid and supplementary subzero chilling may elicit a better response to a subsequent extreme chilling. In the present study, winter-acclimated Chrysemys picta (painted turtle) hatchlings were put in groups that were cold-conditioned to -3, -7, and -10.5°C. These turtles were later chilled to a more extreme temperature (-12.7°C) and monitored for recovery to determine the magnitude of the cold-conditioning response. To determine the effect of the cold-conditioning, levels of glucose, lactate, and urea were assessed in blood plasma, brain, and liver. Results showed that cold-conditioned turtles fared better, offering higher survival rates than those in the control condition. Turtles cold-conditioned to -3.5°C, however, had both the highest concentration of brain glucose and the highest survival rate. Concentration of brain glucose may be an important factor in determining survival of turtles exposed to cold.

Celebration participants presented their research through a poster display or an oral presentation. Many students expounded on the results of their Senior Inquiry, a multiple-term research project required for most academic programs. Other students shared honors capstone projects or student-faculty research findings. Because of the advanced level of research involved, most of the presenters are upperclass students.

Anne Earel and Stefanie Bluemle, Augustana reference librarians and the event's co-directors, said the Celebration of Learning provided an outlet for students to showcase their accomplishments.

Presentations topics varied greatly and included anthropology, biology, physics, geography, gender studies, theater and more.
