Project Description 

Scientific background

Vulnerable Marine Ecosystems (VMEs), such as deep-sea coral gardens and sponge fields, are biodiversity hotspots that deliver critical ecosystem services through their complex structures. However, they face increasing threats from fishing, resource extraction, and climate change. Functional diversity -the range of ecological roles species fulfil within a community -  is central to ecosystem resilience, but remains poorly understood in VMEs. Quantifying VME functional diversity can help assess vulnerability and guide conservation of VMEs. This project will advance our understanding of VME functional ecology and develop science-based indicators of ecosystem health, directly supporting international policy goals for deep-sea biodiversity protection. 

Research methodology

This project will combine seafloor visual survey, targeted sampling and AI-assisted image analyses to:

1. Define and quantify functional traits of VME taxa.
2. Identify key functional groups, map functional diversity, and compare to taxonomic diversity.
3. Develop indicators of ecosystem health and resilience across different VME types.
4. Build predictive spatial models for VME distribution and resilience under future climate scenarios. 

Training

The candidate will gain skills in:

• Deep-sea survey techniques using remotely operated and autonomous underwater vehicles
• Image annotation, including AI-based approaches.
• Functional trait analysis, taxonomic identification of deep-sea benthos, biodiversity metrics; and spatial predictive modelling. 

Professional development will include research cruises, collaboration with international scientific presentations, and co-authorship of additional non-PhD publications. This training will prepare the candidate for careers in academia, environmental consultancy, conservation, and resource management. 

Person specification

We seek a motivated candidate with strong analytical skills, and interest in biodiversity, functional ecology, image/video analysis, and conservation. Experience with programming, statistical analysis, or spatial modelling is desirable but not essential, as full training will be provided. A willingness to join multi-week ship-based fieldwork is welcomed but not required. 

Eligibility

Applicants should have a first or upper second class honours degree in a Biological or Environmental Science or a relevant Masters qualification. You should have strong analytical skills, and interest in biodiversity, functional ecology, image/video analysis, and conservation. Experience with programming, statistical analysis, or spatial modelling is desirable but not essential. 

If your first language is not English, you will need to meet the minimum English requirements for the programme, IELTS Academic score of 6.5 (with no less than 5.5 in each component test area) or equivalent. 

Successful candidates who meet UKRI’s eligibility criteria will be awarded a fully-funded ARIES studentship of fees, maintenance stipend, £20,780 p.a. for 2025/26 (2026/27 rate TBC) and research costs.
