On the macroecology and global distribution of the ecosystem engineer : Sabellaria alveolata in a changing world
The intertidal zone is affected by environmental change in both the marine and the terrestrial realms. All along Europe’s coast, a unique biogenic habitat buffers the shores’ environmental extremes for the high-diversity fauna it hosts: the reefs of the honeycomb worm Sabellaria alveolata. Despite b...

The intertidal zone is affected by environmental change in both the marine and the terrestrial realms. All along Europe’s coast, a unique biogenic habitat buffers the shores’ environmental extremes for the high-diversity fauna it hosts: the reefs of the honeycomb worm Sabellaria alveolata. Despite being listed as a priority European Union habitat, the criteria for assessing candidate reefs have yet to be defined. As a prerequisite to defining the habitat’s ecological status, the aim of this thesis was to further our knowledge of S. alveolata’s ecological niche through an integrated, multi-scale approach. Its niche was explored through the identification and analysis of physiological condition biochemical indicators, which were linked to the outward physical appearance of the bioconstructions in which the individuals resided. Spatial and intraspecific variation in reproductive and biochemical traits were analysed in individuals sampled in ten sites between North Wales and central Portugal. This made it possible to test two divergent theories on the optimal position and environmental conditions for reproduction within a species range. Finally, by constructing a broad-scale occurrence records database which served as the response variable in a species global distribution model, predictive ‘range-long’ maps of present and future suitable habitats were generated for the whole north-east Atlantic coastline.
