Scientific background:

Marine fishes exhibit complex life cycles, featuring discrete spawning, nursery and feeding areas that confer different benefits to the stock. Identifying the ‘Essential Fish Habitats’ supporting our fisheries, and the connectivity pathways linking them, is critical for performing effective spatial management and conservation. European sea bass are an ideal model species to implement a lifecycle management approach as they support important inshore and offshore fisheries, and rely on estuarine nursery areas that are particularly vulnerable to human impacts [1]. However, estimating the importance of specific areas and habitats remains an ongoing challenge, particularly in the face of rapid global change.

Research methodology:

You will use machine learning classification models to improve movement reconstructions using biogeochemical “fingerprints” recorded in bass otoliths (earstones) and eye lenses [2]. You will also validate biogeochemical tracers in archived otoliths using existing tagging data from the same individuals, perform additional fish sampling, and explore whether environmental proxies (e.g. salinity, temperature) help to reduce uncertainty around unsampled areas. You will then integrate these results with other existing datasets (genetics, tagging, modelling [3,4]) to build network models that describe the spatial structure and connectivity of UK bass populations[5] and to predict the outcome of different climate and management scenarios (e.g. MPAs, altered fishing pressure).

Training:

You will be trained in a range of transferable skills, building on the expertise of the supervisory team in fisheries ecology, modelling and biogeochemical tracers. While focused on modelling, you will also be trained in laboratory and field techniques (mass spectrometry, fish sampling). You will also spend three months at Cefas learning additional modelling techniques and best practices to link science, management and policy, and gain access to Cefas’ extensive student networks and professional development activities.

Person specification:

Individuals with an interest in fisheries and conservation ecology, and a degree in biology, ecology, mathematics, marine/environmental science or related fields, are encouraged to apply. Quantitative skills will be important, but there will be considerable training provided. Students with numerical skills but no degree-level exposure to environmental sciences (e.g. Mathematics, Physics, Chemistry, Engineering) are encouraged.

Acceptable first degree subjects: biology, ecology, mathematics, marine sciences, environmental science or related fields.

Key Information

  • This studentship has been shortlisted for funding under the UKRI NERC DLA funding scheme and will commence on 1 October 2025. The closing date for applications is 23:59 on 8th January 2025.
  • Successful candidates who meet UKRI’s eligibility criteria will be awarded a fully-funded studentship, which covers fees, maintenance stipend (£19,237 p.a. for 2024/25) and research funding. A limited number of studentships are available for international applicants, with the difference between 'home' and 'international' fees being waived by the registering university. Please note however that ARIES funding does not cover additional costs associated with relocation to, and living in, the UK, such as visa costs or the health surcharge.
  • ARIES postgradute researcher (PGRs) benefit from bespoke graduate training and ARIES provides £2,500 to every student for access to external training, travel and conferences, on top of all Research Costs associated with the project. Excellent applicants from quantitative disciplines with limited experience in environmental sciences may be considered for an additional 3-month stipend to take advanced-level courses.
  • ARIES is committed to equality, diversity, widening participation and inclusion in all areas of its operation. We encourage enquiries and applications from all sections of the community regardless of gender, ethnicity, disability, age, sexual orientation and transgender status. Academic qualifications are considered alongside non-academic experience, and our recruitment process considers potential with the same weighting as past experience.
  • All ARIES studentships may be undertaken on a part-time or full-time basis. International applicants should check whether there are any conditions of visa or imigration permission that preclude part-time study. All advertised project proposals have been developed with consideration of a safe, inclusive, and appropriate research and fieldwork environment with respect to protected characteristics. If you have any concerns please contact us.
  • For further information, please contact the supervisor. To apply for this Studentship follow the instructions at the bottom of the page or click the 'apply now' link.
  • ARIES is required by our funders to collect Equality and Diversity Information from all of our applicants.

Data will not be shared with those involved in making decisions on the award of Studentships, and will have no influence on the success of your application. It will only be shared outside of this group in an anonymised and aggregated form. You will be ask to complete the form by the University to which you apply.
  • If funded under the BBSRC-NERC DLA scheme, ARIES studentships will be subject to UKRI terms and conditions. Postgraduate Researchers are expected to live within reasonable distance of their host organisation for the duration of their studentship.
