Abstract This study evaluated the spatial and temporal distribution and density of the bivalve Donax striatus, at beaches close to the Apodi/Mossoró River estuary, through, six semiannual sampling campaigns were performed between April/2009 and October/2011. The sampled area was delimited by 20 transects that were laid perpendicular to the beach line and extended over 300 m in the intertidal zone. Seven sampling points were established in each transect, organisms and sediment were collected, and water temperature and salinity were recorded. The highest D. striatus average density (103 individuals.m–2) was observed in April/2009 and the lowest (18 individuals.m–2) in October/2010. The highest D. striatus densities occurred in beaches further from the estuarine region as demonstrated by a significant positive correlation (r2 = 0.67 and p = 0.0007). The D. striatus densities presented significant negative correlations with the percentages of organic matter in the water. This species demonstrated an aggregated distribution in the studied area.

The present study focuses on the structure and dynamics of the ichthyoplankton community of the Mahury estuary (French Guiana) and the factors that influence them. Data were collected on three mangrove sites located in the inner, middle, and outer areas of the estuary. More than 45 000 larvae were collected, representing 31 families and 67 taxa. The community was numerically dominated by few species; Engraulidae was the most abundant family, followed by Gobiidae, Eleotridae, and Sciaenidae. As expected, the most abundant larval taxa were estuarine and mangrove species, with the addition of freshwater species in the inner area of the estuary and taxa with marine affinities in the outer area. The densities of most species were influenced by site more than by season. Temporal variations in the dominant species were influenced largely by their life history strategy, with a majority of the fish species spending their entire life history in mangroves and estuaries.
