Abstract:We present a checklist of 278 species of reef fishes recorded along the coastline of Santa Catarina state, the southernmost limit of distribution of tropical ichthyofauna on the coast of Brazil. regius are reported for the first time, respectively, from the Southwestern Atlantic and for the coastal part of this region, while Acanthurus monroviae is reported for the second time for the Southwestern Atlantic. We present habitat distribution, trophic structure and comment on biogeographic affinities of this transitional region, discussing both remarkable species presences and absences.

“…Approximately 20% of these reef-associated species are endemic to the Southwestern Atlantic (Floeter & Gasparini, 2000;Moura & Sazima, 2003), representing up to 80% of the total number of individuals and/or biomass in local assemblages (Ferreira et al, 1995;Rosa & Moura, 1997; and therefore playing important ecological roles. In the Southwestern Atlantic, coralline reefs occur from the Amazon River mouth to the State of Bahia (0 o 30'-18 o 20'S) (Moura et al, 1999a), but reef fish assemblages occur up to 28 o S, across the entire region with extensive rocky reefs between the Espírito Santo and Santa Catarina States (Moura et al, 1999b;Floeter et al, 2001). Ecological studies focusing on reef fish assemblages are largely focused on tropical coralline reefs (e.g.…”

Local assemblages of fishes associated with reefs are influenced by interactions among the availability of larvae and survival of recruits with subsequent biotic and abiotic forcing, as well as by periodic and episodic disturbances of varying natures and magnitudes. Therefore, besides being structurally heterogeneous and patchily distributed, reef systems are strongly contextdependent due to the influence of a broad array of ecological processes. In order to assess interactions of local factors that influence the distribution and abundance of reef fishes within a coastal mosaic of rocky reefs, we tested the null hypothesis of no significant variation in fish assemblage structure, by comparing 33 sites along the northern coast of the São Paulo State, Southeastern Brazil. Replicated stationary visual census samples (n = 396) were obtained at different distances from the coast, depths and wave exposures, including the mainland, three relatively small coastal islands, and the two margins of a wide channel between the mainland and the large São Sebastião Island (~350 km 2 ), totaling 225 h of SCUBA diving. The regional rocky shore fish fauna comprised 106 species (41 families), with preponderance of diurnal mobile-invertebrate feeders. Samples from the outer margin of the São Sebastião Island, together with those from Alcatrazes, Búzios, and Vitória islands were significantly dissimilar from samples from the coastal sites at the São Sebastião Channel. Species richness tended to increase in a gradient from the coast to the more offshore islands. Local conditions such as depth and other habitat characteristics also influenced fish assemblages' structure. Distance from coast and depth were the main predictors for fish assemblages, followed by water transparency, temperature and benthic cover. This study represents the first regional-scale assessment of fish assemblages associated with rocky reefs in the São Paulo State coast, filling a major geographic knowledge gap in the South Atlantic. As the study region is experiencing fast coastal development and growing threats from seaport expansion, oil and gas exploitation, as well as increasing fishing and tourism pressure, the understanding of the underlying factors that influence the distribution and abundance of the reef-associated biota comprises a relevant baseline for monitoring, conservation planning and management.Assembleias locais de peixes associados a recifes são influenciadas pela interação entre a disponibilidade de larvas e recrutas e as forças bióticas e abióticas que operam após o recrutamento, assim como por perturbações periódicas e episódicas de diversos tipos e magnitudes. Dessa forma, além de serem estruturalmente heterogêneos e irregularmente distribuídos, os sistemas recifais são altamente dependentes do contexto em que se inserem. Com o objetivo de compreender interações de fatores locais que influenciam a distribuição e abundância de peixes recifais em um mosaico costeiro de recifes rochosos, testamos a hipótese nula de inexistência de variação signi...

A B S T R A C TThis study aims to describe for the first time the fish community structure of five shallow reefs located off the cities of Santa Cruz de Cabrália and Porto Seguro (Araripe-AR, Itacipanema-IT, Alagados-AL, Naufrágio-NA and Recife de Fora Marine Park-RF Reefs), South Bahia, Northeastern Brazil. Fish density and richness were assessed through stationary point counts of 2 m radius for small cryptic species and 3 m for more conspicuous species. A total of 1 802 fishes belonging to 23 families and 54 species were observed. The most abundant species were the pomacentrids Stegastes fuscus and Abudefduf saxatilis. No significant differences were found for species richness or density of conspicuous species, but density of small cryptic species was low on reefs with high bottom rugosity, where there were more holes and crevices available. Herbivores were dominant on AR, AL and RF, invertivores on AL and both groups were dominant on IT. Some habitat variables such as rugosity and benthic cover were strongly correlated to species and sites. High bottom heterogeneity was found among reefs but they still presented similar species composition, richness and density. Within small-scale studies, such similarities in composition and richness are to be expected for reef fish communities, as most of the species concerned have a wide distribution range. R E S U M OEste trabalho descreve pela primeira vez as comunidades de peixes em cinco recifes rasos de Santa Cruz de Cabrália e Porto Seguro (Araripe-AR, Itacipanema-IT, Alagados-AL, Naufrágio-NA e Recife de Fora Marine Park-RF), sul da Bahia, nordeste do Brasil. A densidade e riqueza foram obtidas utilizando censos estacionários de 2 m de raio para espécies pequenas e criptobênticas e 3 m de raio para espécies conspícuas. Um total de 1802 peixes pertencentes a 23 famílias e 54 espécies foram registrados, sendo as espécies mais abundantes dos pomacentrídeos Stegastes fuscus e Abudefduf saxatilis. Nenhuma diferença significativa foi encontrada para a riqueza entre os recifes e também para a densidade de espécies vágeis. Entretanto, a densidade de espécies criptobênticas foi mais alta em lugares com maior rugosidade. Herbívoros foram dominantes nos recifes AR, AL e RF, invertívoros em AL e a dominância dos dois grupos ocorreram em IT. Algumas variáveis ambientais como rugosidade e cobertura bentônica estão fortemente relacionadas às espécies e diferentes recifes. Estes são fisicamente heterogêneos, mas a composição e riqueza de espécies similares, o que seria esperado em comunidades recifais abrangendo estudos em pequena-escala, pois peixes recifais estão amplamente distribuídos.
