“…Given the large areas covered by rhodolith beds in the Brazilian Exclusive Economic Zone (EEZ) ( Amado-Filho et al, 2007;Riul et al, 2009;Amado Filho et al, 2010;Pereira-Filho et al, 2012;, their vulnerability to global changes (Feely et al, 2004;Doney et al, 2009) and the high diversity of organisms with recognized potential for bioprospection associated with them, research programs and public policies to conserve their biodiversity and to maintain the sovereignty of these areas are urgently needed.…”

Rhodoliths are the free-living forms of a number of nongeniculate coralline algae. Rhodolith beds are a common feature of subtidal environments and have been recognized as important carbonate producers and paleoenvironmental indicators, as well as recognized as habitat-forming species. The rhodolith structure provides a hard three-dimensional substrate serving as microhabitat for a wide range of biodiversity, including commercially importance species. The largest known latitudinal occurrence range of rhodolith beds ais on the Brazilian coastal shelf from 2°N to 25°S. Despite their importance for the Brazilian benthic communities, only in the last decade sampling efforts allowed a more comprehensive understanding of the beds' distribution, their structure and associated communities, as well as data concerning the infl uence of environmental factors on rhodolith bed structure and dynamics. In this work, we review the available information on the biodiversity associated with the recently described Brazilian rhodolith beds of the continental shelf and oceanic islands, focusing on the associated organisms with potential for bioprospection research.

“…Hydrolithon rupestre was first reported from the Atlantic Ocean by Pereira-Filho et al (2012) who, however, gave no description of the species. Thus, our finding represents the first documented record of the species from that Ocean.…”

“…Most of the recent works on CCA from Brazil (e.g. Amado-Filho et al, 2012;Villas-Boas et al, 2009;Pereira-Filho et al, 2012) is related to unattached, freeliving, rhodolith-forming species, with little modern focus on the attached CCA. The aim of the present study was to determine the species composition of the attached CCA along a depth gradient 0-70 m at the SPSPA.…”

Floristic composition of crustose coralline algae from the St. Peter and St. Paul Archipelago, a summit of the Mid-Atlantic Ridge

et al. 2014

Crustose Coralline Algae (CCA) are important constituents of tropical coral reef environments throughout the world's oceans, acting as structural reinforcement and recruitment cues. Despite their importance and their ubiquity, very little is known of the biodiversity of CCA in remote areas of the world's oceans. On the Saint Peter and Saint Paul Archipelago (SPSPA), located in the central equatorial Atlantic Ocean, CCA occur abundantly in intertidal rock pools and the surrounding subtidal zones. This study represents the first attempt at detailing the CCA species composition for the archipelago along a depth interval between 0 to 70 m. Seven taxa of CCA were identified: Corallinaceae sp., Hydrolithon rupestre, Hydrolithon sp., Lithophyllum johansenii, Lithothamnion muelleri, Mesophyllum engelhartii, and Titanoderma pustulatum pustulatum. A decrease in CCA species richness and change in species composition was seen from shallow to deeper zones that can be explained by a significant reduction in temperature and photon irradiance observed bellow 30 m depth.

“…The forms that grow on the substrate are referred to as rhodoliths when composed mainly (>50%) of CCA (Foster 2001, Harvey & Woelkerling 2007. CCA are recognized to be important carbonate builders in the tropical zone of the Atlantic Ocean, forming reefs and rhodolith beds, especially in Brazil (Riul et al 2009, Amado-Filho et al 2012a, AmadoFilho et al 2012b, Pereira-Filho et al 2012. They also provide refuge areas, habitat, and pasture for numerous species of fish and invertebrates, as well as influence the settlement and recruitment of marine invertebrates through the action of attractive chemicals associated with the surface of CCA, which are known to lead to the establishment of a variety of species of larvae (Farr et al 2009).…”

Taxonomic study of crustose coralline algae off the northeastern Brazilian coast

et al. 2014

View full text Add to dashboard Cite

This work presents a detailed morphoanatomical study of crustose coralline algae species from the northeastern Brazilian coast, in the north of Bahia state. Nine species have been recognized: Sporolithon episporum, Lithophyllum stictaeforme, Spongites yendoi, Spongites sp., Mesophyllum erubescens, Phymatolithon masonianum, Phymatolithon calcareum, Lithothamnion crispatum and Lithothamnion brasiliense. Phymatolithon masonianum and Phymatolithon calcareum constitute the first record of these species for the northern coast of Brazil. An identification key, as well as descriptions, illustrations, comparisons with related taxa, and geographical distributions for Brazil as well as global geographic distributions are presented. Additionally, some ecological implications are discussed focusing the need of more studies about this neglected group of coralline red algae.
