The paper shows that mutation accumulation studies in microbes may have selection bias due to reporting practices and provides a model to estimate selection and mutation spectrum.

This study estimates the fitness effects of new mutations in E. coli and finds they are small and heavily confounded with non-genetic variation.

This paper shows that molecular genetic diversity poorly predicts adaptive potential, using evolvability as a measure of heritable variation across species.

The paper examines interspecific variation in evolvability and heritability across species using phylogenetic models and finds substantial evolvability differences, particularly between plants and animals.

This paper introduces a method to estimate additive genetic variance for relative fitness by tracking population genetic changes, avoiding direct fitness measurements.
