Competition and Coexistence in Yeast Experimental Evolution

Frenkel, Evgeni Mikhailovich (2016-05-19)

Natural selection gives rise to biodiversity by purging the less-fit among variants that are too similar (a principle known as character displacement), but to predict how fit or different an organism needs to be to survive ...
Crowded growth leads to the spontaneous evolution of semistable coexistence in laboratory yeast populations

Frenkel, Evgeni; McDonald, Michael J; Van Dyken, J. David; Kosheleva, Katya; Lang, Gregory I.; Desai, Michael Manish (Proceedings of the National Academy of Sciences, 2015)

Identifying the mechanisms that create and maintain biodiversity is a central challenge in biology. Stable diversification of microbial populations often requires the evolution of differences in resource utilization. ...
The Fates of Mutant Lineages and the Distribution of Fitness Effects of Beneficial Mutations in Laboratory Budding Yeast Populations

Frenkel, Evgeni; Good, Benjamin Harmar; Desai, Michael Manish (Genetics Society of America, 2014)

The outcomes of evolution are determined by which mutations occur and fix. In rapidly adapting microbial populations, this process is particularly hard to predict because lineages with different beneficial mutations often ...
