Environmental DNA (eDNA) analysis is a revolutionary method to monitor marine biodiversity from animal DNA traces. Examining the capacity of eDNA to provide accurate biodiversity measures in species‐rich ecosystems such as coral reefs is a prerequisite for their application in long‐term monitoring. Here, we surveyed two Colombian tropical marine reefs, the island of Providencia and Gayraca Bay near Santa Marta, using eDNA and underwater visual census (UVC) methods. We collected a large quantity of surface water (30 L per filter) above the reefs and applied a metabarcoding protocol using three different primer sets targeting the 12S mitochondrial DNA, which are specific to the vertebrates Actinopterygii and Elasmobranchii. By assigning eDNA sequences to...

Dynamics of fish assemblages on a continuous rocky reef and adjacent unconsolidated habitats at Fernando de Noronha Archipelago, tropical western Atlantic
Provedor de dados: Neotropical Ichthyology
Autores: Medeiros,Paulo R.; Rosa,Ricardo S.; Francini-Filho,Ronaldo B.
In recent years, many studies investigated how density-dependent factors, such as shortages in microhabitat and food availability influence the structure of reef fish assemblages. Most of what is currently known, however, comes from comparisons of isolated patch reefs and from correlations between fish abundance and one or few microhabitat variables. In addition, most studies were done in the Caribbean and Indo-Pacific regions, whereas the South Atlantic region has been, to date, understudied. The present study evaluated spatial and temporal variations in reef fish abundance and species richness in a continuous rocky reef and adjacent unconsolidated habitats in a Southwestern Atlantic reef, using underwater techniques to assess both fish numbers and...

The glassy sweepers' way: seeking a versatile wrasse to be cleaned
Provedor de dados: Neotropical Ichthyology
Autores: Sazima,Cristina; Krajewski,João Paulo; Bonaldo,Roberta Martini; Sazima,Ivan.
Diurnal reef fishes compose the bulk of clients that seek cleaner fishes' services, but some nocturnal species that shelter at daytime also seek the cleaners. While doing so the nocturnal clients must leave their hiding places and thus they get exposed to potential diurnal predators. We report here on the cleaning interactions between a daytime cleaner wrasse (Thalassoma noronhanum) and a night time active client (Pempheris schomburgki) that usually remains sheltered at daytime. We recorded P. schomburgki leaving their shelter at daytime and heading towards T. noronhanum, whenever the cleaner swam by the shelter. Since T. noronhanum is able to tend temporary cleaning station near the safety of the shelters of its clients, P. schomburgki lessens a possible...

A non-digging zoobenthivorous fish attracts two opportunistic predatory fish associates
Provedor de dados: Neotropical Ichthyology
Autores: Sazima,Cristina; Grossman,Alice.
Following behaviour among reef fishes involves mostly a digging nuclear species while foraging, which attracts opportunistic followers preying on the exposed organisms. The flying gurnard Dactylopterus volitans preys on benthic animals, mostly crustaceans and small fishes, scratching and probing the bottom with the inner rays of its pectoral fins. We recorded the flying gurnard being followed by two opportunistic predators, the yellow jack Caranx bartholomaei and the coney Cephalopholis fulva at Fernando de Noronha, off northeast Brazil. Albeit not actually digging the substrate, the flying gurnard acts as a nuclear species by exploring algae tufts and by its wandering near the boulders and ledges, disturbing and flushing out hidden animals which thus...

Spatial distribution of the estuarine ichthyofauna of the Rio Formoso (Pernambuco, Brazil), with emphasis on reef fish
Provedor de dados: Revista Brasileira de Zoologia
Autores: Paiva,Andréa C. G. de; Lima,Marina F. V.; Souza,José R. B. de; Araújo,Maria E. de.
The objectives of the present study were to identify species of reef fish that use the Rio Formoso estuary (northeastern Brazil) as a refuge and natural nursery and to describe the spatial distribution of the estuary fish fauna in rainy and dry seasons. A total of 5475 specimens, across 78 species and 39 families, were analyzed; 51.3% of the species were of reef origin. Among these, Eucinostomus melanopterus (Bleeker, 1863), E. gula (Cuvier, 1830), and Sphoeroides testudineus (Linnaeus, 1758), in this order, were the most abundant in the upper estuary; S. greeleyi Gilbert, 1900, E. melanopterus, and Lutjanus synagris (Linnaeus, 1758) were the most abundant in the mid estuary; and E. gula and Albula vulpes (Linnaeus, 1758) in the lower estuary. The...

Nest building and description of parental care behavior in a temperate reef fish, Chromis crusma (Pisces: Pomacentridae)
Provedor de dados: Revista Chilena de Historia Natural
Autores: Navarrete-Fernández,Teresa; Landaeta,Mauricio F; Bustos,Claudia A; Pérez-Matus,Alejandro.
BACKGROUND: Subtle ecological and behavioral mechanisms that enhance reproduction such as nest building by animals may provide useful information of population level processes. Variation in behavioral traits may be observed as phenotypic traits that are shaped by sexual and natural selection. Using ecological sampling of benthic substrata and underwater video recordings, we assessed nest-building behavior through habitat modifications, and size of individuals performing parental care behavior and egg/hatching traits of an abundant temperate reef fish, Chromis crusma. RESULTS: We identified that only male individuals performed nest building and uniparental care. We noted that nests containing filamentous green or red algae had the highest percent cover of...

Peixes recifais da costa da Paraíba, Brasil
Provedor de dados: Zoologia
Autores: Rocha,Luiz A.; Rosa,Ierecê L.; Rosa,Ricardo S.
The coral reef is an ecossystem which evokes great interest, for its beaury, species diversity and fisheries potential. The coast of Paraíba State, northeast Brazil, possesses several natural reefs and shipwrecks which are inhabited by a rich fish fauna. In order to survey the reef fish fauna of Paraíba State, a total of 118 dives, utilizing SCUBA diving techniques, were carriedoutin 27samplingpoints (depths: 0,5-66m), from February/1995 to May/1996. Specimens were collected whenever underwater identification was precluded. A total of 157 known species belonging to 59 families were found. Four unidentified species, one dasyatid, one haemulid, one scarid, and one labrid were recorded. Haemulidae was the most representative family in number of individuais,...

Community structure of the ichthyofauna associated with seagrass beds ( Halodule wrightii) in Formoso River estuary - Pernambuco, Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Pereira,Pedro H.C.; Ferreira,Beatrice P.; Rezende,Sérgio M.
Seagrass beds are used by juvenile fishes in different ways, generally as nursery sites, shelter from predators, reducing competition and increasing availability of food resources, thus establishing a relationship of connectivity with other ecosystems. In the present study, the community structure of the ichthyofauna associated with seagrass beds on the Formoso River (Pernambuco - Brazil) was evaluated during the winter of 2008. Twenty-seven manual trawls (15 daytime and 12 nighttime) were performed, and a total of 358 fishes belonging to 18 families, 21 genus and 25 species were collected. The Catch Per Unit Effort (CPUE) by trawling average was 13.5 and 4.95 individuals per species per trawl. The most abundant families were Scaridae (n = 111),...
