Abstract
This project aims to determine the cause of the disruption in negative frequency-dependent selection previously displayed between the large (L) and small (S) populations in the A-2 subclade in the Demolition Derby experiment (an extension of the Long-Term Evolution Experiment). The A-2 subclade consists of two stable and co-existing colony types: large and small. Sequenced data provided from the Demolition Derby experiment revealed that the negative frequency-dependent section displayed between the L and S colonies was no longer present. To determine the cause, we performed competition experiments between the A-1 and A-2 subclade and between the A-2 and A+3 subclade since those populations were also in abundance at the end of the Demolition Derby experiment. We then sequenced and analyzed the results. Discovering the answer can help explain niche partitioning and resource utilization within bacteria communities.
