“…Also, organic‐rich mud deposits and moderately well sorted coarse‐grained sands partly derived from the reef were accumulated in the back‐reef zone. Associated reef‐derived sand bodies were depleted in bioclasts contrary to the worm tubes forming the reef that play an important role in storing carbonate bioclasts (Noernberg et al , ). On the other hand, a slight south‐westward expansion of the reef was noted.…”

ABSTRACT1. Reefs built by the annelid worm Sabellaria alveolata in the Bay of Mont-Saint-Michel (France) are the most extensive intertidal biogenic structures within Europe. Before and after mussel farming extensions, a study designed to provide a biological health index of the Sainte-Anne reef (223 ha) was carried in 2001 and 2007 to serve as an easy-to-use management tool and to ensure endangered reef portions were properly targeted and protected.2. Coupled physical and biological parameters were included in a spatial Health Status Index (HI). A spatial and temporal mapping survey of the HI showed a continuous deterioration of the reef's state of health, particularly in its central part. This degradation correlates with the colonization of the Pacific oyster Crassostrea gigas and with increasing silt deposits on the reef.3. A combination of several factors is likely to explain such rapid reef deterioration: (1) an increase in trophic competition between cultivated and wild suspension-feeders that is detrimental to the annelids; (2) a modification in the hydrodynamics and consequently in sedimentary patterns leading to an increase in silt deposition; and most importantly (3) an increase in recreational harvesting of oysters and associated reef trampling, resulting in reef fragmentation.4. Understanding the parameters that influence the reef dynamics is necessary in order to help efficient and effective management and policy focusing on the conservation status of large biogenic structures.

“…They typically provide extremely productive and diverse habitats due to their structural heterogeneity and three-dimensional complexity, which can enhance local biodiversity by making available new resources, including shelter and food, to associated species (Dayton 1971). Moreover, as tube-builders and suspension feeders, they can interfere with sedimentary processes (Noernberg et al 2010) and play a key role in trophic webs (Dubois et al 2003). According to Dubois et al (2002Dubois et al ( , 2006, S. alveolata reefs host rich and unique assemblages consisting of species coming from both subtidal and intertidal areas and from both muddy and sandy substrates.…”

Amphipod assemblages associated with the biogenic reefs built by the honeycomb worm Sabellaria alveolata were studied at two sites (Praia da Aguda and Belinho) along the northwestern coast of Portugal. A total of 3909 specimens were collected, comprising 14 different amphipod species. A first record from the northeastern Atlantic coast was registered here for the species Caprella santosrosai, which was, up to now, recorded only along the Mediterranean coast of the Iberian Peninsula. A male specimen collected from the Sabellaria-reef located in Belinho allowed an update to the known distribution of C. santosrosai, thus altering its previous status as an endemic Mediterranean species. The most common species collected during the study were Microdeutopus chelifer (n = 1828), Jassa ocia (n = 1426), and Hyale stebbingi (n = 452). Forty-three percent of the total recorded species were encountered in both study sites, whereas the remaining 57 % were restricted to a single site (Belinho). The majority of the collected species (93 %) showed an Atlantic-Mediterranean distribution, confirming the close affinity between eastern Atlantic and Mediterranean amphipod assemblages and the role of the Portuguese coast as a transition zone through which numerous warm-water species, coming from North Africa and the Mediterranean Sea, could enter into the Atlantic and possibly get mixed with species coming from the North Sea and the Arctic, typically having affinity for colder waters.

“…Some marine polychaetes from the family Sabellariidae Johnston, 1865 are gregarious and are important reef-building organisms in coastal environments (Goldberg, 2013). These ecosystem engineers create complex habitats supporting high levels of biodiversity and provide ecosystem services such as coastal protection (Dubois et al, 2002;Noernberg et al, 2010;Ataide et al, 2014). While most sabellariids are solitary, the species that are reef-building typically construct biogenic structures in intertidal or shallow subtidal environments (Faroni-Perez et al 2016).…”

Aim To verify the synonymy of the reef‐building polychaete Phragmatopoma caudata (described for the Caribbean) and Phragmatopoma lapidosa (described for Brazil) using molecular data. To evaluate the patterns of genetic diversity and connectivity among populations from Florida to South Brazil. Location Intertidal zone in the western Atlantic biogeographical Region: Brazil, eastern Caribbean and Florida (USA). Methods DNA sequence data from one mitochondrial (cox‐1) and one nuclear ribosomal (ITS‐1) loci were obtained from 11 populations of P. caudata spanning the coasts of Brazil, eastern Caribbean and Florida. Phylogenetic relationships among populations of P. caudata and other members of the genus were inferred by Bayesian methods. Population differentiation was evaluated by Bayesian analysis of population structure (baps), AMOVA and pairwise φst. Demographic history was inferred by Bayesian skyline plots. Results Phylogenetic inference supported the interpretation of a single species of Phragmatopoma spanning the Brazilian and Caribbean Provinces of the western Atlantic Region. Little population structure was observed across the species distribution, with the exception of the Florida population. The baps analysis supported a 2‐population model, with population differentiation being strong and significant between Florida and all other Atlantic populations for cox‐1, and significant between Florida and most populations for ITS‐1. Differences in genetic diversity were not significant between Caribbean and Brazilian populations, although several populations in Brazil had low values for diversity indices. Bayesian skyline plots indicate population expansion starting at c. 200 ka. Main conclusions Phragmatopoma caudata is able to maintain genetic connectivity across most of its geographical range, with population differentiation being observed only between Florida and all other localities, possibly due to ecological speciation in the transition zone between tropical and subtropical environments. Long‐distance connectivity across much of the species range is likely the result of long‐lived larvae that are tolerant to a wide range of environmental conditions.
