Lecturer, University of Bath
The research in the Priest lab lies at the interface of evolution, behavioural ecology, reproductive physiology and molecular genetics. Much of this work involves parental effects, which occur when the physiology and genotype of mothers influence trait expression in offspring. We have found that older mothers produce offspring with reduced longevity in fruit flies. We have found that maternal exposure to toxic compounds in male seminal fluid stimulates parental effects which improve the fitness of daughters. We have also found that mating increases the rate of genetic recombination in the maternal genome. Population genetic theory and life history models that we have constructed show that parental effects can alter the rate, direction, and endpoint of phenotypic evolution. These findings indicate that parental effects have an integral role in trait expression and evolution.

The current projects in the lab extend from our previous findings. We conduct empirical studies to understand how physiological responses to sexual behaviour in parents contribute to the rate of adaptation. We take advantage of the power of Drosophila genetics to understand how parental effects and recombination rate operate at a molecular level. To motivate and evaluate the empirical studies, we develop explicit cross-generational population genetic and demographic models. The ultimate goal of the work in the Priest lab is to resolve classic questions about aging, sexual behaviour and sex.
