“…Mesophyllum engelhartii has been confirmed for Australia (Woelkerling and Harvey 1993), New Zealand (Harvey et al 2005), Namibia (John et al 2004), and South Africa (Chamberlain and Keats 1995). The rhodoliths from this study comprised seven crustose coralline species in five genera (Hydrolithon, Lithophyllum, Lithothamnion, Mesophyllum, and Neogoniolithon), a high richness of coralline red algae compared with other studied tropical and temperate rhodolith beds (e.g., Steller et al 2003, Goldberg 2006, Konar et al 2006, Harvey and Bird 2008, Peña and Bárbara 2008, Basso et al 2009). This diverse community of nongeniculate corallines (see also Amado-Filho et al 2007) is largely responsible for the construction of the rhodolith structure and consequently acts as an ecosystem engineer.…”

Esta diversa comunidad de algas coralinas no geniculadas (ver Amado-Filho et al 2007) es en gran parte responsable de la construcción de la estructura rodalítica y, por lo tanto, actúa como ingeniero de ecosistemas.…”

Seaweed diversity associated with a Brazilian tropical rhodolith bed

et al. 2010

ABSTRACT. This study describes the predominantly tropical, subtidal seaweed populations growing on rhodoliths between 4 and 18 m depth in the southern part of Espírito Santo State (Brazil). Qualitative and quantitative sampling revealed species-rich algal communities, comprising 167 species. Three species of rhodophytes represent new records for the Brazilian marine flora (Lithothamnion muelleri, Scinaia aborealis, and Mesophyllum engelhartii). Marked seasonal differences in fleshy algal species composition and abundance were related to seasonal instabilities caused by winter-storm disturbance over the rhodolith beds. In relation to depth, rhodolith density appears to be an important factor for the variation in the abundance of fleshy algae. The rhodolith community is composed of at least seven nongeniculate crustose coralline algal species. Rhodolith beds in southern Espírito Santo State, in an area of 150 km 2 , provide an important habitat for epibenthic communities, supporting 25% of the known macroalgal species richness along the Brazilian coast.Key words: rhodoliths, marine algae of Brazil, benthic algal community, Espírito Santo State, crustose coralline algae. RESUMEN.Se describen las poblaciones de las macroalgas submareales predominantemente tropicales que crecen sobre rodolitos entre 4 y 18 m de profundidad en la parte sur del estado de Espírito Santo (Brasil). Muestreos cualitativos y cuantitativos revelaron comunidades ricas en especies de algas, incluyendo 167 especies. Tres especies de rodofitas son nuevas adiciones a la flora marina de Brasil (Lithothamnion muelleri, Scinaia aborealis y Mesophyllum engelhartii). Las marcadas diferencias estacionales en la composición y abundancia de especies de algas carnosas se relacionaron con la inestabilidad causada por el disturbio de tormentas invernales sobre los mantos de rodolitos. En cuanto a la profundidad, la densidad de rodolitos parece ser un factor importante para la variación en la abundancia de algas carnosas. La comunidad de rodolitos está formada por al menos siete especies de algas coralinas no geniculadas. Se demostró que los mantos de rodolitos, en un área de 150 km 2 , proporcionan un hábitat importante para las comunidades bentónicas, manteniendo 25% de la riqueza de especies de macroalgas conocidas para la costa brasileña.Palabras clave: rodolitos, algas marinas de Brasil, comunidad algal bentónica, estado de Espírito Santo, algas coralinas incrustantes.

“…e Atlantic maerl elements are mostly unattached, fruticose coralline plants or fragments of plants belonging to one or a few species. e maerl corallines form nonnucleated rhodoliths, of the unattached branches category (Bosellini & Ginsburg 1971;Bosence 1976;Basso 1998;Birkett et al 1998;Basso et al 2009). Mediterranean maerl has been identified to 65 m (Huvé 1956;Jacquotte 1962;Babbini et al 2006) and coralline biodiversity is greater than that of most Atlantic and Pacific analogues (Birkett et al 1998;Riosmena-Rodríguez et al 1999;Bressan et al 2001;Peña & Bárbara 2006;Babbini et al 2006;Giaccone et al 2009).…”

Maerl-bed mapping and carbonate quantification on submerged terraces offshore the Cilento peninsula (Tyrrhenian Sea, Italy)

On the continental shelf off the Cilento peninsula (eastern Tyrrhenian Sea) the occurrence of more than 13 km 2 of maerl beds was documented through acoustic surveys. Swath bathymetric data along with a dense grid of chirp-sonar profiles were acquired over more than 180 km 2 . e maerl facies was characterized on the basis of the components analysis of 32 grab samples collected at selected sites. Mapped maerl-beds are predominant on submerged terraces located at variable water depth (wd) between 42 and 52 m. is preferred distribution on submerged terraces is probably associated with relatively vigorous bottom currents generated by local circulation that hinders the deposition of terrigenous sediments. Calcareous red algae result to be the most important producers of carbonates from 40 down to 60 m wd. We calculated the coralline carbonate accumulation from the percentage cover of coralline algae (thin section mapping) × 1 cm-thick layer of sediment × measured coralline density. e total coralline cover (living plus dead) in the Cilento area is 13.96 km 2 , with a total 316 800 tons of algal carbonate in the surface 1 cm layer, that correspond to 20 430 g m -2 . Living maerl is recorded at a depth of 47 m, with a live coralline
