New paper on male reproductive ageing in PNAS
6 years in the making, our new paper dissects the roles of seminal fluid versus sperm in mediating reproductive ageing in males. We also found that the decline can be postponed – read here! |

Stuart Wigby is an evolutionary biologist. In the lab we study sex and death, mainly using the fruit fly, Drosophila melanogaster, as a model organism.
We are interested in sexual selection, sexual conflict, speciation, sperm competition, kin selection, immunity, life history and ageing. |

We've moved to the superb Department of Evolution, Ecology & Behaviour, in the new Institute of Infection Veterinary and Ecological Sciences at the University of Liverpool. It is an exciting place to be – come join us!

When do female flies get aggressive after mating? Is it the same for different strains? Does machine learning work for scoring fly female aggression? See our new paper to get the answers!
MAR 2020
Our new paper in Roy Soc Open Sci identifies odd looking 'presences' (for want of a better word) in the spermathecal ducts of some female flies. They seem to associate with sperm competition outcomes.
FEB 2020
Dresden here we come! In February I'm heading to the Technische Universität Dresden for 6 months as a Dresden Senior Fellow, to set up new collaborations with Klaus Reinhard.
NOV 2019
Another PNAS paper, again led by Ben Hopkins. This one shows how activity of Drosophila male prostate-like secondary cells influences the seminal proteome & sperm dynamics in the female. Twitter thread here
AUG 2019
Our PNAS paper, led by Ben Hopkins, shows how males can alter their sperm and seminal fluid proteins differently in response to rival males. Complete with explanatory video!
