“…The similarity matrix was calculated using the Sørensen index, and the clusters generated by the hierarchical agglomerative method using the UPGMA amalgamation strategy. The seven areas included in this study were: (1) Ceará -CE (present study; Araújo et al, 2000;Cunha et al, 2007Cunha et al, , 2008Freitas et al, 2009); (2) Maranhão -MA (Rocha & Rosa, 2001;Nunes et al, 2011a, b); (3) Risca do Zumbi RN -ZU (Feitoza, 2001); (4) Paraíba -PB (Rocha et al, 1998;Souza et al, 2007;Honório et al, 2010); (5) Abrolhos -AB (Moura et al, 2006); (6) Atol das Rocas (Rocas Atoll) -AR (Rosa & Moura, 1997;Floeter et al, 2008); and (7) Arquipélago de São Pedro e São Paulo (St Paul's Rocks) -SPSP (Lubbock & Edwards, 1981;Feitoza et al, 2003).…”

“…The final checklist of reef fish from Ceará, including the intertidal and subtidal zones, comprises both the species observed during the dives and those from the previous records available (Araújo et al, 2000;Cunha et al, 2007Cunha et al, , 2008Jucá-Queiroz et al, 2008;Freitas et al, 2009 ; Table 1. Details of the sampling sites, including depth, distance from the coast, geographic coordinates and type of reef (natural or artificial).…”

Based on data from 151 underwater surveys (scuba) between 2002 and 2007, the present study assessed the reef fish fauna from a scarcely known region on the north-eastern Brazilian coast (Ceará State). A checklist of 179 taxa is provided and the zoogeographic patterns are analysed and discussed, including six other localities. Based only on assemblage composition, the reef fish fauna from Ceará showed a strong resemblance (73%) with the reefs of Risca do Zumbi (RN) and Paraiba (PB). The data from the visual censuses including abundance values corroborate the evaluation based only on composition and suggest ecological factors as the main drivers of the fish assemblages in the region.

“…Microhabitat characteristics within rock pools might also be important for understanding the behaviour of different species and their interactions with environmental factors, such as pool dimensions and type of bottom (Lara & González, 1998; Gratwicke & Speight, 2005), which may vary according to wave exposure, tidal cycles and anthropogenic influence (Campbell & Pardede, 2006; Freitas et al , 2007; Cunha et al , 2008).…”

Local v. microhabitat influences on the fish fauna of tidal pools in north‐east Brazil

This study explored the influence of microhabitat characteristics, such as sandy, rocky and algal bottom, holes, area and depth, on tide-pool fish descriptors (evenness, total number of fish, diversity and species richness). Even when the rockpool microhabitats differed amongst beaches, the tidal fish assemblages were closely grouped by site rather than by characteristics of the tide pools. Fish assemblages were mostly represented by juvenile fishes from 29 species, of which 14 were observed in only one of the three sites. This indicates that sites, rather than microhabitat association, might play a major role for the rockpool ichthyofauna in north-east Brazil.

“…Research on the effects of habitat fragmentation by deepening of channels and removal of wetland vegetation in Lake Huron (Uzarski et al ., ), damage to commercial fisheries from marine sand mining in Korea (Kim & Grigalunas, ), the response of the fish community to the dredging operations of coastal rivers in the BioBio region in Chile (Ortiz‐Sandoval et al ., ), the response of tidal creek fishes to dredging and coastal development pressures in Lynnhaven River (Chesapeake Bay) (Bilkovic, ), interannual changes in benthic fish populations in the eastern region of the English Channel after sand and gravel mining (Drabble, ), and harbour construction effects on reef fish communities in north‐east Brazil (Freitas et al ., ), are types of indicators reported. Experiments evaluating the risks of prolonged exposure to high concentrations of suspended sediment (SS) in orange‐spotted grouper Epinephelus coioides (Hamilton 1822), an important mariculture species that has a wide distribution in the Indo‐Pacific, showed that damages to gill structure were evident and strongly correlated with SS concentration (Au et al ., ).…”

Changes in the environment and in the composition of fish assemblages in the Paranaguá Estuary (South Brazil) were assessed by comparisons made before, during and after dredging operations, in the same months and areas studied in the previous year. Interactions between year and month were observed for salinity. During the dredging year fish total density was 2 individuals m(-2) and with a total biomass of 104 g m(-2) (among 31 species captured). For the same period the year before, 0·3 individuals m(-2) and 3 g m(-2) were captured (38 species). The number of species showed significant time v. month interactions, assuming that fish species composition varied for both year and month. Total mean density and biomass showed significant differences for interaction time v. month, and density and biomass in the dredging month September 2001 in the main channel were scientifically different from other months. Interaction times v. area were significant for Cathorops spixii (increased biomass), Aspistor luniscutis (increased density), Menticirrhus americanus (decreased biomass) and Cynoscion leiarchus (decreased density and biomass). This suggests that during the dredging process there is a change in the structure of the demersal fish assemblage. The impact (damage and mortality) induced by dredging on the macrobenthic animals along the dredge path attracted adults of C. spixii that reached densities 10 times greater than in the year before. On the other hand, sciaenid species practically disappeared. To contribute to the conservation of the estuarine fish fauna, and maintain fisheries production of the Paranaguá Estuary and surrounding areas, it is recommended that, dredging should be done from the late rainy season to the early dry season. Decisions must take into account the ecological cycles of socio-economically important fish species and prioritize the safe disposal of dredged spoils.
