Profile

Dr Debbie Russell
Senior Research Fellow

Research Overview:

I am interested in the marine ecosystem and species at the interface between the marine and terrestrial environments, namely seals and seabirds which are dependent on the marine ecosystem for food but on the terrestrial environment for breeding. I am particularly interested in interactions on various levels: among different taxa, between species and humans, and between species and their changing environment.

Key research topics

• Investigation of seal population trends and their drivers.
• Using a mixture of Bayesian and frequentist methods to analyse harbour and grey seal telemetry data to answer both pure and applied research questions.
• Investigation of the impact of anthropogenic structures, their construction, operation and decommisioning, on marine predators.
• Using movement and behavioural data within a state-space modelling framework to define activity budgets.
• Modelling interactions between seals and fisheries in a spatial context, using state space models.
• Modelling the effect of climate variation on British seabirds.
