“…In the Barra Velha, Araçá I and Araçá II sectors, diversity increased from the upper toward the lower levels, confirming the results found by many investigators (MCLACHLAN 1990, RIZZO & AMARAL 2001. Olivella minuta showed clear zonation patterns, being more abundant in the lower levels, especially in the Araçá I and Araçá II sectors.…”

“…CORBISIER (1991), NETTO &LANA (1995) andBORZONE et al (1996) worked with zonation of macrofauna in beaches of different morphodynamic types. The zonation patterns suggested by DAHL (1952) and SALVAT (1964) were compared to patterns in Barranco Beach by SOUZA & GIANUCA (1995), and in São Francisco Beach by RIZZO & AMARAL (2001). LOPES & SCHAEFFER-NOVELLI (1992), BORZONE (1994) and DENADAI et al (2001) studied the community structure and spatial distribution of mollusks.…”

ABSTRACT. The spatial distribution of mollusks in the intertidal zone was examined monthly from August 1995 through July 1997, in Enseada, Barra Velha and Araçá beaches in southeastern of Brazil. One study sector was selected in Enseada and Barra Velha, and two sectors in Araçá (Araçá I and Araçá II). The sectors were 10 m wide and equivalent in length to the width of the intertidal zone. Each sector was divided into three horizontal levels: lower, middle and upper, where the samples were taken with a cylinder corer with a base area of 0.16 m 2 . In order to characterize the intertidal environment in these areas, some environmental variables were analyzed. In general, the mollusks were distributed in the sectors as follows: Enseada -Olivella minuta (Link, 1807)

“…The peak abundances found in soft-bottoms with higher values of fine grains and TOM, demonstrated that the general distribution pattern of total polychaetes is not the same for all abundant polychaete species. L. treadwelli has been recorded in both intertidal (RIZZO;AMARAL, 2001) and inner shelf (20 to 50 m depth) environments in SE Brazil (PAIVA, 1993a), but unlike the present study, the literature does not indicate any grain size preference of the species. This study is the first record of L. treadwelli on the Abrolhos Bank, although other species of the genus Scoloplos (previous genus of L. treadwelli) are commonly found in the area .…”

Erosion on coral reefs produces fragments of the constructor organisms that are scattered all around, thus enlarging the reef boundaries. Statistical modelling approach was used to investigate whether the Polychaeta community around Sebastião Gomes reef (Abrolhos Bank, Brazil) is influenced equally by sediment characteristics and/or by position related to the reef, that are variables related to the terrigenous input influence. In July 2007, a period dominated by winds that resuspend fine sediment from the land to coastal reefs, sediment samples were taken on four transects perpendicular to the reef (S, W, N and E) and a total of 121 species of polychaetes were recorded. The most abundant species was the carnivorous Goniadides carolinae and the model selected for it approximates to the best models fitted for both total macrofauna and polychaete abundance. These models represented higher abundance in coarse carbonate sediments on windward reef faces, where there is almost no terrigenous sediment. On the other hand, the Polychaeta richness did not depend on the transects. Sebastião Gomes reef is one of the many coastal reefs from Abrolhos Bank, whose healthy is probably in danger because of the increase of mud related to human activities, as deforestation and, recently, mining waste.

ABSTRACT. Modeling the distribution patterns of the estuarine macrobenthic community has revealed itself as a difficult task due to spatio-temporal heterogeneity. This study uses ordinary kriging and Poisson modeling to generate distribution maps of the subtidal benthic macrofauna in the Trapandé Bay (southeastern Brazil). Samples were taken in duplicate from 36 locations distributed along nine transects perpendicular to the main estuarine axis in October 2006 and March 2007. One-hundred and seventy taxa belonging to 12 phyla, were identified, with dominance of Annelida Polychaeta. Distribution maps were prepared to illustrate the total density, the number of species and the six most numerous taxa, as well as abiotic parameters. The general distribution pattern has revealed that the greatest number of species and the highest densities are at the estuary mouth, decreasing towards its inner areas. However the temporal and spatial changes observed at the estuary mouth have clearly shown the impact of environmental variations such as nutrients and freshwater input, attributed to increased rainfall in March. The increased flow in the Cananeia Sea, coming from the drainage basin, produces major changes in sediment and faunal composition. Ordinary kriging associated with Poisson modeling has proved to be a powerful and promising tool for modeling the macrofauna, despite the fact that it is not frequently used due to the scarcity of appropriate software.
