Understanding cetacean distributions and habitat use through environmental DNA
Environmental DNA (eDNA) is developing rapidly as an important tool for biodiversity monitoring and for exploring ecological interactions. eDNA is especially useful for uncovering species presence and distributions for elusive or hard to observe species in remote locations, or environments that are logistically challenging to access. We have recently demonstrated the power of eDNA for monitoring of common and rare cetaceans (including Minke whales, harbour porpoise, bottlenosed dolphins and Sowerby’s beaked whale) in a marine protected area in the Moray Firth, northeast Scotland, UK, and for uncovering spatio-temporal patterns in species presence and ecological interactions with their prey.
In this PhD project, we will build on our current work to expand the spatial and temporal coverage for the Moray Firth and potentially other areas with the aims of:
- Evaluating the environmental and ecological factors influencing spatial and temporal habitat use by minke whales, harbour porpoise and bottlenose dolphins
- Explore the drivers of spatio-temporal variation in marine community structure and species interactions
- Develop and test improved methods for marine eDNA sampling to expand spatio-temporal coverage
The project will be co-supervised by Dr Maria Beger and Elizabeth Boyse (University of Leeds), Dr Kevin Robinson (Cetacean Research and Rescue Unit), Dr Elena Valsecchi (University of Milano Biocca), and potentially other collaborators from the UK cetacean eDNA network which is currently under development.
Funding & Eligibility: A variety of competitive scholarships are available which support UK home rated students (UK citizens, and those satisfying relevant UK residency criteria)
Alternatively we can consider overseas students supported by external scholarships.
How to apply: Applications will be made via the Faculty of Biological Sciences Graduate School Portal (https://biologicalsciences.leeds.ac.uk/research-degrees), but it is essential that you email me (firstname.lastname@example.org) before submitting an application.
