“…The complexity of the internal channeling system of the S. polyschides holdfast may offer larger and more protective areas for this fauna (McKenzie and Moore 1981) than the sediment interstitial spaces. Several studies also suggest that hard substrates are more important for Syllids than soft substrates (e.g., Antoniadou et al 2004;Liñero-Arana and Díaz 2011;Serrano et al 2006). Faulwetter et al (2011) recorded only 23 species in soft-bottom samples (in Israel) when compared to the 62 species found in several hard substrates (e.g., filamentous Phaeophyceae and Chlorophyceae, Jania sp., Cystoseira sp.…”

The diversity, distribution and ecology of the family Syllidae along the Western Iberian coast was studied, based on 145 sediment samples covering the whole Portuguese coastal shelf and 30 Saccorhiza polyschides holdfasts sampled in the north of Portugal. A total of 55 species were identified in 2,306 specimens. A total of 33 species were recorded in the holdfasts and 36 in the shelf samples spanning a wide range of sediments, bathymetry and latitude. A total of 14 species were shared between both substrates. A total of 26 species were here firstly recorded, increasing to 80 the number of species known in Portugal, and new insights were added to the ecology and geographic distribution of several species. A multivariate analysis identified three assemblages, characterized by the species (a) Sphaerosyllis bulbosa and Syllis pontxioi in the western shelf coarse sediments, (b) Parapionosyllis brevicirra and Syllis mercedesae in the southern shelf muddy sands and (c) Brania pusilla and Myrianida brachycephala in the kelp holdfasts. The type of substrate (kelp holdfast vs. soft-bottom sediments) and the sediment grain size (coarser vs. finer) were the descriptors best related to the Syllid assemblages.

Abstract:The polychaete fauna of the Caribbean coast of Costa Rica has been inadequately characterized with only nine species previously reported. Collections of polychaetes from intertidal coralline rocks and several shallow sub-tidal sites on the Caribbean coast of Costa Rica have been examined and 68 species were identified. Of these, 66 are new records for Costa Rica. Rev. Biol. Trop. 65 (1): 127-152. Epub 2017 March 01.

“…Currently the northernmost known occurrence of the species in Brazil is in the state of Piauí (Santos et al ., ). Beyond the Amazon and Orinoco Rivers, the species has also been recorded in Venezuela (Liñero‐Arana, ). Discontinuities in the range cannot at present be stated with certainty, as field observations in this geographical region are far from exhaustive, and areas with confirmed absences have yet to be described.…”

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.
