Abstract This paper presents a checklist of the reef fish fauna of the Anchieta Island State Park, a no-take zone in which no extractive activities are allowed, in Ubatuba, Southeastern Brazil. Data was obtained between 2011 and 2013, mainly through underwater observations with snorkelling and SCUBA, and secondarily using scientific fishing (trawling). Published and unpublished data were also verified and compiled. A total of 103 reef fish species, distributed in 78 genus and 50 families was recorded. Haemulidae was the richest family (n=7 species), followed by Epinephelidae (n=6), Pomacentridae, Carangidae and Tetraodontidae (n= 4 each). Haemulon was also the most speciose genera (n=5), followed by Stegastes, Acanthurus and Mycteroperca (n=3 each).... |

ABSTRACT When confronted by predators, prey need to make an economic decision between continuing their current activity or flee. Flight Initiation Distance (FID), the distance at which an organism begins to flee an approaching threat, has been used to indicate an animal's fearfulness level and a way to examine factors influencing escape decisions. Here we investigated how the FID of the barber surgeonfish, Acanthurus bahianus, responds to the presence of spearfishers in a fishing site in northeast Brazil. Specifically, we examined whether the FID was influenced by body and group size; by the heterogeneity of species in groups formation; and the distance to shelter. Significant differences in FID were observed with increasing body size. We found no... |

Ocean rocky formations are known as islands. When islands become completely submerged, they are called stone slabs. Like reefs, these formations alter the flux of water produced by the waves, which in turn interacts with the adjacent sediment, altering the sediment and its undulation marks. The alterations caused by the interaction between the waves and emerged or submerged rigid structures can potentially alter the composition and the distributional patterns of the infauna of the adjacent, unconsolidated substrate. In order to evaluate the strength of these alterations, we sampled the infauna and the sediment adjacent to two ocean structures, one emerged and one submerged. Collecting was performed in winter and summer, while discriminating between the... |
