“…Previous work across the world has recurrently highlighted that this habitat holds a large diversity and quantities of marine invertebrates (e.g. Bosence, 1979;Giménez-Casalduero, Rodríguez-Ruiz, Vivas, & Ramos-Esplá, 2001;Hinojosa-Arango & Riosmena-Rodríguez, 2004;Metri, 2006;Prata, Costa, Manso, Crispim, & Christoffersen, 2017;Otero-Ferrer et al, 2018), revealing the importance of these habitats as refuge sites for the young stages of mollusks and several commercial fishing stocks (Riosmena-Rodríguez et al, 2017). Rhodoliths may thus be considered hotspots of biodiversity.…”

ABSTRACT. Introduction: Rhodoliths are biogenic structures distributed worldwide, formed by several types of calcareous algae. They may host a great diversity of marine invertebrates, among which polychaetes are conspicuous and diversified representatives. Rhodolith beds are notwithstanding vulnerable to several human activities (e.g. exploitation of commercial species associated with rhodoliths, petroleum exploration, fishing activities, effluent discharges, and tourism), which may compromise that diversity. Tourism is presently increasing its impact on rhodolith beds. Global warming and ocean acidification are also determinant factors in faunal change. Objective: to analyse the polychaete assemblages associated with rhodolith beds subject to different intensities of touristic pressure at Seixas Beach (NE Brazil), where tourism is gradually increasing over time. Methods: Effects were evaluated at two depths, 1.5 m and 4.0 m. Sampling was done every two months during 2015, encompassing the two marked seasons of the year in the region (rainy and dry). Quadrats of 15 x 15 cm were placed in each depth during sampling. All rhodoliths present within the quadrat were collected (usually four to five rhodoliths). Our hypothesis was that the deeper depth and the samples from the dry season months would be increasingly subject to the impact of tourism. Results: Overall, 49 species were found (from 21 different families), and a total of 733 individuals were collected. The most abundant species was Eunice wasinensis (280 individuals, 38.2% of total abundance). The species Eurythoe complanata, Eunice biannulata, E. wasinensis, Lysidice ninetta, Oxydromus pugettensis and Ceratonereis (Ceratonereis) singularis appeared in all months. The study detected a tendency for higher diversity to occur at the depth of 1.5 m for all indices, but only the Shannon-Wiener values were significantly higher there (p < 0.05). No clear differences were found regarding months or season. Conclusions: These results suggest that a higher potential pressure due to tourism may occur at 4.0 m due to more intense craft shipping activities (traffic of catamaran boats transporting tourists to and from the reefs) in that area.

“…In tandem with understanding the structural roles of rhodoliths, there is a need to investigate the direct and indirect effects of rhodolith species on biodiversity and ecosystem processes including the food webs and energy flows associated with rhodolith beds (e.g., Grall et al, 2006), cycling of nutrients (e.g., McConnico et al, 2018), the provision of microhabitats for settlement and recruitment (e.g., Meihoub Berlandi et al, 2012;Prata et al, 2017). The multiple roles and the multiple scales over which interactions occur are exemplified by the role of rhodoliths as refugia for associated species-whether serving as a refuge for escape from predation of scallops within rhodolith beds (e.g., Kamenos et al, 2004), or providing structure for colonisation by species from ˃1 mm (e.g., Teichert, 2014), or serving as holobionts supporting a diverse biota of associated microscopic life stages (e.g., Fredericq et al, 2019;Krayesky-Self et al, 2017).…”

Rhodolith beds provide heterogeneous and complex threedimensional habitats, providing ecosystem services disproportionate to their size (Lundquist et al., 2017), and meeting the definition of foundation species provided by Dayton (1972). Rhodoliths, or maerl, are calcified red algae that are free-living (Foster, 2001;Riosmena-Rodríguez et al., 2017) and are found globally from high to low latitudes (McCoy & Kamenos, 2015). Their morphological complexity and the interstitial spaces they provide serve as a refuge from predation for small invertebrates, as well as important settlement and nursery substrates for epiphytes, epifauna, and

This study investigates the marine macroinvertebrate fauna of rhodolith beds (non-geniculated red corallinaceaous algae) in northeast Brazilian. A total of 57 species were identified, belonging to six phyla (Platyhelminthes, Annelida, Sipuncula, Mollusca, Arthropoda and Echinodermata), of which 50 are considered here as new records for the Paraíba State. Annelids (Class Polychaeta) were the most representative taxa in Miramar and Seixas Beaches, while molluscs were dominant in Maceió Beach. This is the first study that includes an identification key, diagnostic features and distribution patterns worldwide and local (including new records) of the marine invertebrate fauna associated with rhodolith beds in northeast Brazil (State of Paraíba). Sampling events were performed in 2018, at low tide in the intertidal to shallow subtidal zones (1.5 and 4.0 m depth), in Miramar, Seixas and Maceió Beaches. A total of 17 species were found for the first time on Seixas Beach, as well as all identified species for Miramar and Maceió. This study tries to contribute to the knowledge of marine invertebrates in northeast Brazilian shallow habitats, providing a baseline for future environmental studies.
