Demonstration of fundamental ecological patterns and processes using research-level material associated with seagrass ecosystems.
I am a subtidal benthic ecologist with a research emphasis on the effects of human pressure on the state of subtidal structural benthic habitats and the subsequent changes in ecosystem functioning and provision of ecosystem services. I am particularly interested in the structure and functioning of seagrass habitats at a landscape scale (fragmentation, depth squeeze, connectivity). In recent years I have spent a lot of time in bridging the knowledge gap between science and policy: assessing conservation importance, identifying suitable indicators for monitoring change and advising on the design and management of marine protected areas.
Presently I am working on the following topics/papers:
- Assessing the economic contribution of Posidonia to secondary production in the Mediterranean;
- Aggregate European carbon (and carbon dioxide) storage (Climate Change mitigation effects) benefit in European seagrass habitat;
- Habitat suitability modelling of Zostera marina;
- Assessment of spawning and nursery areas of the cuttlefish Sepia officinalis
- MPA network planning for the future – examining implications of minimising fishing displacement and effects of ASH shoaling;
- Effects of seagrass landscape configuration on fish and invertebrate communities and the implications for provision of ecosystem services;
- Effective use of biological traits information for assessing ecosystem function, monitoring and conservation management;
- Large scale patterns in UK benthic biodiversity; and
- Long-term changes in seagrass distribution in the Isles of Scilly – a potential mooring system for promoting seagrass recovery.
