Global climate change is causing drastic alterations to nutrient content and availability for a variety of species. The multifaceted effects of climate change mean that all domains of life are vulnerable. This raises questions about whether or not organisms will be able to evolutionarily adapt to their new nutrient conditions. Here, we sought to explore the influences of different microbial diets on C. elegans fitness. We calculated egg laying and hatching rates of nematodes grown on three bacteria genus. Initial experimentation showed marked differences in C. elegans fitness as a result of food source. Further, in developing an experimental evolution procedure, we investigated whether C. elegans could evolutionarily adapt to its diet in just 15 generations. Overall, we found no differences in fitness over time for worms grown on either E. coli or B. subtilis.
