Signal, noise, and sampling: how pool size and replication shape metabolomic inference
Abstract. Metabolomics provides direct insight into physiological state, but for small organisms such as Drosophila melanogaster, it typically requires poo

Recent work from the lab. Even after hundreds of generations of intense directional selection at relatively small Ne, substantial genetic variation persists, and can be rapidly redeployed when the direction of selection reverses. Results are suggestive of balancing selection. doi.org/10.1093/molb...

Beyond Fixation: Persistent Genetic Variation Under Intense Selection
Abstract. Understanding how and why genetic variation is maintained under sustained selection remains a central question in evolutionary genetics. Experime
