54 weeks of evolution later...
How does pairwise versus diffuse coevolution alter the evolutionary trajectory of mutualism? Do opportunities for specialization increase rewards achieved through the interaction? Does generalism increase ecological flexbility in environmentally variable conditions? These are all questions Kayla aims to address using a model system of Saccharomyces cerevisiae strains obligately dependent on one another for amino acid cross-feeding. Kayla has evolved mutualistic strains under selection for mutualism with strict partner fidelity and other strains under selection for mutualism with diffuse partner fidelity. She will now work with Ratcliff lab member Dung Lac and undergraduate mentee Kristine Yin to evaluate the eco-evolutionary consequences of these disparate coevolutionary dynamics. Stay tuned!
