Ecological and demographic factors can significantly shape the evolution of microbial populations
both directly and indirectly, as when changes in the effective population size affect the …

Microorganisms commonly inhabit energy-limited ecosystems where cellular maintenance
and reproduction is highly constrained. To gain insight into how individuals persist under …

How genetic variation is generated and maintained remains a central question in evolutionary
biology. When presented with a complex environment, microbes can take advantage of …

… cerevisiae is problematic (MG Behringer, unpublished data) due to their repetitive nature,
so mutations in these genes may have been missed in that study. In addition, given our …

Over the last decade, mutation studies have grown in popularity due to the affordability and
accessibility of whole genome sequencing. As the number of species in which spontaneous …

Yeast species are extremely diverse and not monophyletic. Because the majority of yeast
research focuses on ascomycetes, the mutational determinants of genetic diversity across …

Following the completion of an adaptive evolution experiment, fitness evaluations are
routinely conducted to assess the magnitude of adaptation. In doing so, proper consideration …

Interactive microbial communities are ubiquitous, influencing biogeochemical cycles and
host health. One widespread interaction is nutrient exchange, or cross-feeding, wherein …

Ecotypic diversification and its associated cooperative behaviors are frequently observed in
natural microbial populations whose access to resources is often sporadic. However, the …

Diverse ecosystems host microbial relationships that are stabilized by nutrient cross-feeding.
Cross-feeding can involve metabolites that should hold value for the producer. …
