A PhD position is available at the University of Glasgow based in the lab of Kevin Parsons, with co-supervision with Chris Harrod (Glasgow), Heidrun Feuchtmayr (UK Centre for Ecology and Hydrology), Jason Newton (Glasgow), and Clayton Magill (Herriot-Watt University). The studentship is funded, including stipend, along with a research and training budget as part of the NERC IAEPETUS DTP Full details and application portal can be found here: https://iapetus.ac.uk/studentships/examining-ecological-shifts-and-impacts-of-adaptive-divergence-in-response-to-geothermal-habitats/ Project description: - Climate change poses a major threat to biodiversity, but some populations will undergo ecological shifts to persist with impacts on the supporting ecosystem. How this will occur is unknown but in some areas of geothermal warming unique opportunities are provided to investigate the ecological impacts of a warmed habitat. - In Iceland's geothermally warmed habitats, we have discovered several populations of threespine stickleback. This has driven adaptive divergence in metabolism, morphology, and behaviour. However, evidence also suggests that ecological differences in diet occur. This could drive much of the adaptive divergence observed, while also impacting the broader community. - This project will look directly at the dietary changes that occur in these populations to better understand the ecological drivers of thermally- driven adaptive change. To achieve this the project will address three main aims: - 1. Analysis of long-term dietary variation using stable isotopes to compare between populations from geothermal and ambient habitats (across multiple locations) - 2. Assess ontogenetic variation in diet to determine at what life stage ecological divergence occurs - 3. Tests of heritable divergence in diet preferences, performance, and bioenergetic partitioning through the use of lab-rearing and mesocosm experiments - Field work will take place in Iceland, while mesocosm experiments will be conducted at the UK Centre for Ecology and Hydrology. We the candidates with the ability to work in a team as they will be part of a dynamic and social group of PhD students and postdocs at Glasgow. The lab meets weekly to discuss papers of interest, project ideas, explore methodologies, and to practice presentations for conferences or within the institute. The University of Glasgow is a top 100 institution, with research expertise in many areas offering a stimulating environment. Eligibility: This postion is avaible to both UK and international students. The Iapetus programme will be holding an online Q&A application workshop on the 26th of November, but further details are currently available at https://iapetus.ac.uk/how-to-apply/#Eligibility Interested applicants should contact Kevin Parsons directly with a CV and statement of interest before the 8th of December if they are an International applicant, while UK applicants should be in touch before the 15th of December. This will provide time for the different processes and the final deadline of the 5th of January 2026 to be met. Note: IAPETUS has alos introduced the Diversifying Talent Scholarship Scheme, with provides a separate competition for underrepresented groups (details on https://iapetus.ac.uk/).
