Name: Siobhan Vye


I am a marine ecologist who started out at Bangor University before moving to Belfast to complete my PhD on the wild rocky shores of Ireland. My PhD research investigated the interactions among multiple anthropogenic stressors and the cumulative effects on biodiversity and ecosystem functioning, using rocky shores as a model system. After completing my PhD research, I moved to the wilds of Scotland (Aberdeen) to work for the Joint Nature Conservation Committee, where my role was to provide scientific advice on marine protected areas (MPAs).

My research interests are in marine invasive species ecology and biodiversity-ecosystem functioning relationships. To date, my research has focused on how environmental context, including the presence of other anthropogenic stressors, may alter the effects of invasive species on biodiversity and ecosystem functioning.

I am also enthusiastic about public engagement in science and getting people interested, curious and knowledgeable about the diverse habitats and biological communities of our coasts and the wider benefits these habitats provide to us.  I am currently working as  the North Wales Project Officer for “Capturing our Coast”, a national marine citizen science project funded by the Heritage Lottery Fund that aims to train and support a network of volunteers around the UK to record the abundance and distribution of intertidal species.

I am interested in theoretical and experimental ecology, particularly that of a multi-disciplinary nature. My research history concerns 5 main interest areas: 1) biotic interactions, particularly herbivory, plant-animal and predator-prey interactions in macrophyte ecosystems; 2) landscape ecology, especially to understand the drivers of spatial heterogeneity in ecosystem processes; 3) the effects of disturbances on plant and animal species; 4) ecosystem stability and alternative stable states, such as the assessment of nutrient-linked moderation of trophic cascades in macroalgal systems, and 5) drivers and consequences of animal movement on ecosystem function.

I am a Sêr Cymru research fellow within the RESILCOAST Cluster at Bangor University led by Dr Martin Skov. In RESILCOAST, I am conducting a review of the global status of salt marshes, experiments on the influence of grazing on salt marsh erosion rates and developing models to analyse how marsh geomorphodynamics responds to perturbations in sediment supply, biodiversity, plant productivity, grazing and sea level rise.
