The reproduction and connectivity of Sabellaria alveolata reefs in Wales - MAR4REF (2014)
The reef building tube worm Sabellaria alveolata is an important ecosystem engineer on UK shorelines and is subsequently protected as a result of its limited spatial distribution in reef form. To effectively manage and reduce impacts on populations resulting from environmental change, more information is required to understand the distribution and development of S. alveolata reefs. The purpose of this data capture was it collect information to help understand the distribution and development of Sabellaria alveolata reefs in order to effectively manage and reduce impacts of populations resulting from environmental change. The associated report presents the findings from a Welsh Government Resilient Ecosystems Fund funded project lead by Bangor University investigating the reproduction and connectivity of S. alveolata reefs along Welsh coastlines. Three key sites for data collation, Llanddulas (north Wales), Aberarth (mid-Wales) and Dunraven (south Wales), but expanded to the regional scale for modelling larval movements between major reef sites throughout the Irish Sea. The main research areas included: 1) Laboratory-based experiments to describe larval behaviour in relation to phototaxis and quantification of swimming speed throughout different larval development stages. 2) We assessed adult fecundity and egg sizes from worms collected from all three study sites every month from February-Sept 2014. 3) We measured larval densities in the water column at all three sites during the theorised reproductive period. 4) We produced estimates of population connectivity for different reef sites within Wales and determined major source and sink sites by using a biophysical model to create estimates of larval movement.

Methodologies included: - Laboratory-based experiments - Experiments and field surveys looking at phototactic behaviour (the movement of a organism to, or away from a light source) - Plankton netting - Measurements of adult fecundity, egg size and larval densities and produce estimates of population connectivity for different reef sites within Wales. Survey, laboratory studies and analyses carried out by staff of the Bangor University.
