| Habitat dynamics interacting with species dispersal abilities could generate gradients in species diversity and prevalence of species traits when the latter are associated with species dispersal potential. Using a process‐based model of diversification constrained by a dispersal parameter, we simulated the interplay between reef habitat dynamics during the past 140 million years and dispersal, shaping lineage diversification history and assemblage composition globally. The emerging patterns from the simulations were compared to current prevalence of species traits related to dispersal for 6315 tropical reef fish species. We found a significant spatial congruence between the prevalence of simulated low dispersal values and areas with a large proportion of... |

| The reef fauna connectivity of the West Indian Ocean (WIO) is one of the least studied globally. Here we use genetic analyses of the grouper Epinephelus merra (Bloch 1793) to determine patterns of connectivity and to identify barriers to dispersal in this WIO marine area. Phylogeographic and population-level analyses were conducted on cytochrome b sequences and microsatellites (13 loci) from 557 individuals sampled in 15 localities distributed across the West Indian Ocean. Additional samples from the Pacific Ocean were used to benchmark the WIO population structure. The high level of divergence revealed between Indian and Pacific localities (of about 4.5% in sequences) might be the signature of the major tectonic and climatic changes operating at the... |

| Epinephelus merra (Serranidae) is the most common and widespread species of this genus, mostly found in reef habitats from South Africa to Central Pacific. Thirteen polymorphic microsatellite loci were isolated and characterized from this species. Polymorphism was studied in two localities from the Comoros archipelago-Moh,li and Moroni. Allelic diversity was 7.5, polymorphism ranging from 3 to 13 alleles. Overall heterozygosity was high with an average observed heterozygosity of 0.587. Three of these loci were characterised by heterozygote deficiencies for both populations. Finally, ten of the 13 developed primers could be used in future population genetics study of E.merra that might be useful in a context of marine biodiversity conservation. |

| In this study we analyze the population structure and diet of the coney Cephalopholis fulva at Trindade Island, Brazil, through direct observation with SCUBA diving in 11 reef sites around the Island, up to 50 m deep. Diet was based on 77 individuals collected with speargun. Mean population density and biomass were estimated at 29 individuals/100 m² and 13 kg/100 m², respectively. This species is regularly distributed along the costal environments of the Trindade Island, with no significant differences in densities and biomass detected among the different collection habitats (reef crest, reef slope, and reef plateau). However, significantly higher densities were observed micro-habitats with greater structural complexity, which may offer more shelter and... |

| The oogenesis is a key stage in the reproductive development of an organism, which can be best understood from histological analysis of ovaries in different maturity stages. In order to provide information on the reproductive biology of the black triggerfish, M. niger, in particular on its oogenesis process, this study aimed at identifying and characterizing the oocyte development stages and its organization within the different stages of ovarian maturation based on specimens from São Pedro e São Paulo Archipelago. In this present report, a number of 294 ovaries were histologically analyzed. It was verified that they are composed of ovigerous lamellae containing oocytes at different development stages. Five different stages of oogenesis were identified:... |

| The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological... |

| This study aimed to assess abundance and habitat use by juvenile and adult damselfishes, as much as the benthic cover of different reefs on Isla Colon, Bocas del Toro, Panama. Reefs were selected considering different levels of wave exposure and depths. Damselfish and benthic communities were distinct between reefs. The most abundant species in the sheltered deeper reef was Stegastes planifrons followed by S. leucostictus, and they were also recorded in the sheltered shallower reef. Low densities of S. partitus and S. variabilis were also observed in the sheltered deeper reef, as these species are apparently restricted to higher depths. Additionally, these reefs presented patches with high cover of live and dead massive coral. Shallow depths presented high... |

| The yellowcheek wrasse Haliocheres cyanocephalus (Bloch) is registred by the first time for the Colombian Caribbean. In spite of extensive diving in most reef areas of Colombia since 1980, H. cyanocephalus was observed only in four occasions at the Tayrona Natural Park, the Urabá area, and San Andrés islands. The fish is known to occur in deep waters but in Colombia it was found only in shallow (7-15 m in depth)reef environments. Eight species of the genus Halichoeres are now known from the Colombian Caribbean. |

| Many coral reef fish species aggregate at specific times and locations for the purpose of spawning. This study examined the spatial and temporal distribution of spawning aggregations in the Seychelles. An interview-based survey of the principal stakeholders, mainly artisanal fishers, yielded 89 reports of aggregation fishing for 26 demersal and semi-pelagic fish species. Grouper aggregations were largely concentrated in the outer coralline islands of the exclusive economic zone, whilst those of snappers and rabbitfishes were mainly reported from locations on the Seychelles Bank. The spatial patterns among fish families were attributed to a combination of differences in species abundance and distribution as well as variation in fishing effort. Spawning... |

| Five coral reef areas at the Colombian Caribbean were assessed between 1998 and 2003 through the “National Coral Reef Monitoring System of Colombia” (SIMAC), recording 198 species of fishes. The highest species number was observed in Chengue bay (149), including four new records for the Santa Marta area. At San Andrés Island, 138 species were identified, with nine new records for the Archipelago. At the Rosario Island, 128 species were recorded with eight new records, while 114 species and 12 new records were observed at San Bernardo Islands. Of the 119 fish species recorded at the Urabá area, 48 are reported for the first time. |

| The first studies undertaken in Mozambique regarding reef fishes were carried out at Inhaca Island in the final 30’s (Lopes 1937; 1938). In the 50’s and 60’s, mainly taxonomic studies were conducted and reef fish species lists were made available especially for Inhaca Island (e.g. Smith 1958; Sanches 1963; Smith 1968). Only recently, investigations of other aspects of the reef fish fauna has begun. Kalk (1995) elaborated on the trophic composition of the reef fish fauna at Inhaca Island and Loureiro (1998) studied the artisanal reef fisheries in Mécufi District, north of Mozambique. Under the Darwin/Frontier Mozambique project (Whittington et al. 1998) the diversity, species composition, abundance and fisheries of the coral reef fish fauna of the Quirimbas... |

| Se realizó una evaluación rápida de las asociaciones de peces en el sector oeste del litoral norte de La Habana, el cual está sometido a un alto nivel de estrés ambiental. Se hicieron censos visuales mediante transeptos lineales en siete estaciones de dicha zona, en cada una de ellas se realizaron 6 réplicas de 50 m de largo por 2 m de ancho, siguiendo la metodología AGRRA. Los valores más bajos de densidad y biomasa se encontraron en las estaciones situadas al este del área de estudio (La Puntilla, calle 70 y calle 180), las cuales están más afectadas por la contaminación. La ictiofauna en todo el sector se caracterizó por una baja densidad, biomasa y talla de peces depredadores (pargos, meros, jureles, etc.) y herbívoros (fundamentalmente loros), al... |

| It is important to establish benchmark reef locations that are remote from centres of human activity and free from anthropogenic disturbances, against which human impacts elsewhere can be assessed and rates of recovery evaluated. Aldabra Atoll in the southern Seychelles, is free of anthropogenic disturbances and an ideal location in which to study reefs and adjacent ecosystems. It has further significance with it being in the middle of a region which has been classified as having a number of reefs at high risk (Bryant et al., 1998) and has been designated as a UNESCO World Heritage site. |
