Abstract	Artificial habitats, such as harbours and marinas, are entry doors for the introduction and dispersal of species. Surveys on fouling community in these habitats help to understand preventing environmental impacts and management of invasive species. Thus, a survey on fouling bryozoan fauna was carried out along 17 artificial habitats (eight harbours and nine marinas) from three coastal stretches in Southwestern Atlantic. A total of 55 species were identified, including 13 non-native, 33 cryptogenic and nine native taxa. Only five bryozoan species were found in more than 75% of sampled sites. Our analysis revealed that bryozoan fouling communities in artificial habitats do not vary significantly between commercial and recreational localities. However, we also found that faunal assemblages varied significantly along Brazilian coastal stretches that are distinguished by environmental conditions, such as salinity and temperature.

Abstract	Bryozoans are commonly associated with various artificial structures in marine environments and have been responsible for several bioinvasion events worldwide. Understanding the interactions between bryozoans and artificial structures is therefore essential to prevent the establishment and spread of potential bioinvaders. This study investigated bryozoan recruitment on four different substrates (PET, nautical ropes, metal, and PVC) placed in three orientations (vertical, horizontal facing down and facing up) in an area of the Western Atlantic. In total, 15 species of bryozoans were found. The results revealed significant variations in assemblages' richness, with bryozoans showing a preference for settling on PVC (14 species found) and on the underside of horizontal substrates (15 species found), resulting in the higher representativity observed in this study. Cryptogenic (nine species) and exotic (five species) bryozoans dominated the assemblages in all treatments, indicating that the type of substrate (especially artificial) and its orientation can favor the settlement of bryozoans, particularly non-native species. Therefore, the availability of multiple types of artificial substrates in marine environments should be treated as a cause for concern.

Abstract	Despite a recent increase in the number of taxonomic studies on the bryozoan fauna of northeastern Brazil, new discoveries and re-examination of museum specimens allow the continued recognition of new taxa. Here, we describe ten new cheilostome species from the northeastern continental shelf of Brazil based on different museum collections. The new species are: Thalamoporella tupinamba n. sp., Turbicellepora papula n. sp., Plesiocleidochasma brasiliensis n. sp., Plesiocleidochasma infundibulum n. sp., Rhynchozoon turgidum n. sp., Cribrilaria brasiliensis n. sp., Hippoporina titan n. sp., Crepidacantha fasciata n. sp., Crepidacantha browni n. sp., and Hippopodina inarmata n. sp. Some specimens previously reported from northeastern Brazil are here reassigned to the newly described taxa, and two new combinations, Cribrilaria caraguata (Winston Vieira, 2013) n. comb. and Cribrilaria tuba (Winston Vieira, 2013) n. comb., are proposed.

Abstract	Free-living bryozoans, unlike most cheilostomes, live unattached from the substratum on or within soft sedimentary bottoms. Bryozoans of the family Cupuladriidae Lagaaij, 1952 are probably the best-studied free-living representatives. In Brazil, eight species of cupuladriids have been reported to date, including some regarded as species complexes. This paper documents cupuladriid taxa from northeastern and northern Brazil based on the examination of 1236 colonies. Three species previously reported from Brazil are described: Cupuladria monotrema (Busk, 1884), Discoporella gemmulifera Winston Vieira, 2013 and Discoporella salvadorensis Winston, Vieira Woollacott, 2014. A new species, Cupuladria minuta n. sp., is erected; it differs from its congeners in having small, flat discoid colonies, with the central area up to the fifth astogenetic generation composed of vicarious avicularia with an auriform opesia, and quadrangular to rectangular basal sectors with 1-6 small openings per sector. Our results suggest that four species previously recorded from Brazil are doubtful-Cupuladria canariensis (Busk, 1859), Cupuladria biporosa Canu Bassler, 1923, Discoporella umbellata (Defrance, 1923) and Discoporella depressa (Conrad, 1841). Some Brazilian specimens previously assigned to Discoporella umbellata var. conica are re-assigned to D. salvadorensis. The species studied here frequently co-occur on mainly sandy and muddy bottoms at 8-130 m depth, as it is typical of most living populations of cupuladriids. The sedimentation rate, and thus the bottom composition, likely influence the distribution of cupuladriids in Brazil, with Cupuladria species being more common in stabler and coarser sea bottoms than Discoporella species, which tend to be more broadly distributed.

Article: The role of artificial habitats on fouling bryozoan fauna in the southwestern Atlantic

Xavier, Everthon A / Almeida, Ana C.S / Vieira, Leandro M

Marine pollution bulletin. 2021 June, v. 167

2021

Abstract	Artificial habitats, such as harbours and marinas, are entry doors for the introduction and dispersal of species. Surveys on fouling community in these habitats help to understand preventing environmental impacts and management of invasive species. Thus, a survey on fouling bryozoan fauna was carried out along 17 artificial habitats (eight harbours and nine marinas) from three coastal stretches in Southwestern Atlantic. A total of 55 species were identified, including 13 non-native, 33 cryptogenic and nine native taxa. Only five bryozoan species were found in more than 75% of sampled sites. Our analysis revealed that bryozoan fouling communities in artificial habitats do not vary significantly between commercial and recreational localities. However, we also found that faunal assemblages varied significantly along Brazilian coastal stretches that are distinguished by environmental conditions, such as salinity and temperature.

Abstract	At date, seven species of Stylopoma Levinsen, 1909 are reported from the Brazilian coast, five of which are known from Bahia State in the northeastern region. Here we describe four new species of Stylopoma, all from Bahia State: Stylopoma corallinum n. sp., Stylopoma faceluciae n. sp., Stylopoma multiavicularia n. sp. and Stylopoma sinuata n. sp. Unlike the Caribbean species of Stylopoma, that mainly have rounded primary orifice and slit-like sinus, the morphology of the primary orifice of Brazilian taxa, including the new species presented here, is quite variable. In the newly described taxa, the sinus is drop-shaped in S. corallinum n. sp. and S. faceluciae n. sp., U-shaped in S. multiavicularia n. sp. and V-shaped in S. sinuata n. sp. Like congeners from the Caribe, S. corallinum n. sp., S. faceluciae n. sp. and S. multiavicularia n. sp. have avicularia on the surface of the ooecia. Remarks on the morphological characters currently used in Stylopoma taxonomy are provided, including a comparative table of all living species worldwide.

Abstract	Bryozoa is a phylum of aquatic invertebrates widely distributed around the world, including harbor areas. They have association to artificial structures as main mechanism of dispersal, including ships, which facilitates their introduction to new environments. The detection of exotic species is important to prevent new introductions and to propose management strategies of marine areas. Thus, after analyzing and discussing local and global criteria of exotic species, an account of exotic bryozoans from Brazil is presented, including 12 classified as exotic (six established and six detected) and 17 classified as potentially exotic (cryptogenic). Three species have been reported causing economic or environmental impacts worldwide. Of those, Membraniporopsis tubigera is known to cause economic impacts on the Brazilian coast. Hull fouling is the main dispersal mechanism for exotic bryozoans. The lacking of reliable data did not allow inferring on the exotic status on some fouling bryozoan species in Brazil.

Abstract	Biological and abiotic processes influence ecosystem structure and species distribution. For bryozoan assemblages, depth, substratum and habitat structure are among the main factors influencing their distribution. Ecological studies on bryozoan fauna from Brazil are scarce and factors affecting the distribution and/or diversity of this common group are obscure. Here we attempted to verify the influence of bathymetry on bryozoan richness on the north shore of Bahia State, north-eastern Brazil. We identified 57 bryozoan taxa, comprising 35 families and 50 genera, all belonging to the Cheilostomata. Retevirgula multipunctata Winston, Vieira & Woollacott, 2014 and Tetraplaria dichotoma (Osburn, 1914) and the genus Aimulosia Jullien, 1888 were recorded for the first time from Bahia State. Species growing as encrusting sheets were dominant at all depths. There was a significant difference in richness among samples at different depths, with highest values of richness at 40 meters (Kruskal-Wallis Test). Analysis of similarities revealed a significant difference among the bryozoan assemblages, mainly when comparing assemblages from 10 and 20 meters with deeper ones. Also, shallower assemblages composition varied much than assemblages from 30 and 40 meters. Since depth is a proxy for several environmental parameters, further studies are needed to identify other factors influencing bryozoan distribution.

Abstract	Brittle stars are considered one of the main benthic groups at the Brazilian coast, where they occur in high abundance and diversity. Ophiothrix Müller Troschel, 1840 is among the most common genera of ophiuroids, with hundreds of specimens deposited in Brazilian Zoological Collections. Here we reviewed the species of Ophiothrix of Brazil and elucidated the taxonomic status of the six species previously reported in Brazilian waters-Ophiothrix ailsae Tommasi, 1970, Ophiothrix angulata (Say, 1825), Ophiothrix brachyactis H. L. Clark, 1915, Ophiothrix rathbuni Ludwig, 1882, Ophiothrix suensoni Lütken, 1856 and Ophiothrix trindadensis Tommasi, 1970. Three of these were not found among the 1.134 specimens analyzed in this study-O. ailsae, O. angulata and O. brachyactis. Most specimens previously attributed to these three taxa are here assigned to Ophiothrix brasiliensis n. sp. due having disc covered by short spines with 2-6 thorns at the apex and triangular radial shields covered only by short bifid and trifid spines. Three other new species are also described. Ophiothrix spiniformis n. sp. has a disc covered by long spines with denticules along their complete length and an apex with spinelets and radial shields covered by short bifid and trifid spines. Ophiothrix tommasii n. sp. is characterized by the interradial regions of the disc and radial shields being covered by spines with 2-7 thorns at the tip, and by the presence of small spines on the first dorsal arm plate. Ophiothrix troscheli n. sp. has a disc covered by long conical spines and naked, triangular radial shields. An identification key for the Ophiothrix species of Brazil is provided.
