Connectivity modelling informs metapopulation structure and conservation priorities for a reef-building species
Aim: In coastal marine systems, biogenic reef-building species have great importance for conservation as they provide habitat for a wide range of species, promoting biodiversity, ecosystem functioning and services.

Aim: In coastal marine systems, biogenic reef-building species have great importance for conservation as they provide habitat for a wide range of species, promoting biodiversity, ecosystem functioning and services. Biogenic reef persistence and recovery from perturbations depend on recolonization by new recruits. Characterizing larval dispersal among distant reefs is key to understanding how connectivity shapes metapopulation structure and determines network coherence; all of which are of critical importance for effective conservation. Location: Northeast Atlantic coast and western English Channel, France. Methods: We used a biophysical transport model to simulate larval dispersal of the reef-building polychaete Sabellaria alveolata. We combined dispersal modelling and network analysis into a framework aiming to identify key reef areas and critical dispersal pathways, whose presence in the network is vital to its overall coherence. We evaluated changes in dispersal pathways constrained by different connectivity thresholds, i.e., minimum dispersal rate for the presence of a connection. We tested scenarios of sequential loss of reefs: randomly, by habitat quality (a score for reef status and occupancy in an area) or by betweenness centrality metric (BC; quantifying the proportion of shortest paths connecting all areas that are passing through any given area).
