We are seeking a skilled and highly motivated postdoctoral researcher to become part of our research team. The preferred starting date is between 1 December 2025 and 1 February 2026, for a duration of two years. We study how the environment affects contemporary evolution and its predictability, using laboratory and field data of Trinidadian guppies. Global change rapidly alters species? environments, raising concerns about their ability to evolve fast enough to avoid extinction. Whether species will persist or disappear is often unclear as existing methods to predict contemporary evolution work poorly when applied to natural populations. Recent research suggests that environmental variability is an important reason why evolution in the wild is so difficult to predict. We thus study how the environment affects estimates of heritability, mean fitness, and selection, and thereby potentially the predictability of trait evolution. To do so, we combine quantitative genetic experiments in a newly established, state-of-the-art fish research laboratory with analyses of long-term field data, using the wellknown Trinidadian guppy system. The environmental aspect we mainly manipulate in the laboratory is food availability, because changes in food availability are among the most widespread effects of anthropogenic change. You will join Assistant Professor Anja Felmy?s research group at Lund University to work on projects that involve statistical and quantitative genetic analyses of both laboratory and field data. You will also be involved in data collection by conducting experiments in the fish laboratory. While the focus of the position must be aligned with the group?s scientific vision, the successful applicant will be able to influence his or her specific research questions. The application deadline is 31 October 2025.
