“…For instance, fish which inhabit a greater variety of habitats typically present distinct physiologic adaptations, intraspecific variability in fish behaviour (Bourke et al 1997, Silva-Falcão et al 2012) and greater functional specialization and originality (Sales et al 2016). Our results support this information as species which were common to both habitats (e.g., Atherinella brasiliensis and Mugil curema) have been previously reported in literature as presenting high plasticity in their diet (Rueda 2002, Contente et al 2010) and great tolerance to changes on environmental conditions that are typical of coastal environments (Neves et al 2006, Albieri et al 2010.…”

Background. Assessing patterns in habitat utilization and changes in the composition of biont assemblages is a key tool for efficient ecosystem conservation planning and management. Nevertheless, habitat use patterns by juvenile fish still need more comprehension. Therefore, the presently reported study investigated relations between the type of nursery ground and the structure of juvenile fish assemblages in a tropical coastal area of the south-western Atlantic. Materials and methods. From December 2009 to November 2010, we conducted monthly sampling of ichthyofauna in two habitat types (mangrove and sandy beach) used as nursery grounds by juvenile fish of the south-western Atlantic. Species richness and abundance were used to identify spatial and temporal patterns in the distribution of fish assemblages throughout habitats' dynamics. Results. A total of 845 fishes representing 16 families and 34 species were found during the presently reported study: Albula vulpes (Linnaeus, 1758); Atherinella brasiliensis (Quoy et Gaimard, 1825) Ginsburg, 1933; Sphyraena barracuda (Edwards, 1771); Sphoeroides testudineus (Linnaeus, 1758). No significant differences in species richness and total abundance were found between habitats and seasons. Nevertheless, our analyses showed that distinct sets of species use these areas. Moreover, we identified a strong relation between the rainfall and the species turnover in both habitats studied. Conclusion. Diversity of nursery grounds in coastal areas not only increases fish diversity but also plays an important role in the sustaining fish stocks.

“…(), is explained by two biological characteristics of the species. First, silverside reproduction is highly dependent on estuaries, and a considerable part of the species life cycle occurs in this environment (Neves et al ., ). Spawning occurs at estuarine inlets, in calm and shallow waters with great abundance of vegetation (Bemvenuti, ), which acts as a substrate for the silverside's adhesive eggs (Fávaro et al ., ).…”

Aim Sea‐level changes and coastal geomorphology (extension of continental shelves) have affected the pattern of diversification of brackish/freshwater fish populations due to the confluence of basins/estuaries during low sea‐level periods (opportunity) and isolation during high sea‐level periods. It is hypothesized that populations from estuaries in extensive continental shelves, which have greater potential for confluence, should have more opportunities for gene exchange than those in narrow continental shelves. To test this, we assessed the distribution of the genetic diversity and the patterns of diversification of the estuarine silverside, Atherinella brasiliensis, from the Brazilian coast. Location Eight estuaries along the southern and north‐eastern portions of the Brazilian coast. Materials and methods Sequences of the mitochondrial control region (D‐loop) and the cytochrome B were used to assess the distribution of genetic diversity, and these mitochondrial fragments and two nuclear introns were used to assess the patterns of diversification of A. brasiliensis. The palaeochannels that were exposed along the Brazilian coast during the Last Glacial Maximum were reconstructed using bathymetry data and the GIS method. Results The populations of A. brasiliensis from the estuaries of the north‐eastern Brazilian coast (narrower and shallower continental shelf) showed higher levels of genetic differentiation and larger (more haplotypes) endemic lineages than the populations in the southern coast (broader and deeper continental shelf). Furthermore, south coast lineages showed more evidence of genetic exchange among populations, which have resulted in a reticulated relationship between lineages and estuaries. The reconstruction of palaeochannels revealed more connections among southern than north‐eastern basins. Main conclusions Our results support the hypothesis that continental shelf extension and sea‐level changes have influenced the diversification of A. brasiliensis. By extension, they also support the hypothesis of diversification by taxon pulse, which makes predictions based on the opportunities for expansion during periods of low sea level and the width of the continental shelf. We suggest this as a model for the genetic diversification and distribution of estuarine species along the Brazilian coast and other regions of the world.

“…The affinity of A. brasiliensis for the highly structured habitats in Guaratiba Mangrove was reported by Neves et al . (), who found a high contribution of this species to the local ichthyofauna (57.9% of the total number; 54.8% of the total weight). In beaches of Sepetiba Bay that lack mangroves, Pessanha & Araújo () found a relatively lower contribution of this species to the icththyofauna (1.8% of the total number; 5.6% of the total weight), which reinforces the view that the mangrove habitat is a very suitable area for A .…”

“…According to Neves et al . (), A. brasiliensis is an abundant resident species of Guaratiba Mangrove but occurs at comparatively lower abundances in other nearby habitats. Pessanha & Araújo () found the highest abundance of this species in the sandy beaches of Sepetiba Bay close to Guaratiba Mangrove, an indication that the mangrove ‘exports’ A. brasiliensis to sandy beaches nearby and that there is connectivity between these two types of habitat.…”

We compared fish community structure in Guaratiba Mangrove, SE Brazil, among three seasons of the hydrological cycle [(i) spring, increasing temperature and rainfall, decreasing salinity; (ii) summer/early fall, high temperature and rainfall, intermediate salinity; (iii) late fall/winter, low temperature and rainfall, high salinity] and between the years 2002–2003 and 2008–2009. The aim was to test the hypothesis that the fish community structure changes seasonally, associated with seasonal changes in environmental conditions, and that changes occurred between the two yearly periods because of increased anthropogenic activities. The sampling protocol for the two surveys was identical. A total of 63 species was recorded, with 38 species occurring in 2002–2003, and 53 species in 2008–2009. The main changes in the mangrove's fish assemblage between 2002–2003 and 2008–2009 were (i) an increase in species richness, fish density and total biomass; and (ii) an increase in the zoobenthivorous species of gerreids Eucinostomus argenteus, Diapterus rhombeus and Ulaema lefroyi, and a decrease in the planktivorous clupeid Harengula clupeola. Other abundant species, such as the opportunistic atherinopsid. Atherinella brasiliensis, the detritivorous mullet Mugil liza and the zoobenthivorous pufferfish Sphoeroides testudineus did not differ in abundance between the two yearly periods. Ten species occurred only in 2002–2003, and 23 species only in 2008–2009, indicating significant changes in community structure over the 6‐year period. Seasonal changes in community structure were more conspicuous in 2008–2009, when species abundance and richness were greatest. The highest fish abundance was recorded in spring and in summer/early fall, and the lowest in late fall/winter. The increased abundance and richness over time may be at least partially attributable to protection policies because of the effective implementation of a biological reserve in the area.
