Wild Worms Vs. Lab Worms In A Laboratory Ecosystem, Alexis Winner
Undergraduate Research Conference at Missouri S&T
The model organism Caenorhabditis elegans lives artificially in labs since the 1970s. The question at hand is how well adapted the so-called wild-type strain is to these lab conditions. We developed a laboratory ecosystem based on wild type C. elegans and E. coli as food resource to investigate the impact of mutations that affect life history traits. In this project, we explore whether the observed population dynamics reflect wild C. elegans populations. In more detail, we compare the population dynamics of wild type worms and worms collected recently in different parts of the world.
