Structure and dynamics of distinct fish assemblages in three reaches (upper, middle and lower) of an open tropical estuary in Brazil
Estuaries are transitional systems where seasonally fluctuating freshwater river flows meet the daily fluctuating marine tides to create conditions of highly variable salinity and other environmental
Thermal impact of a nuclear power plant in a coastal area in Southeastern Brazil: effects of heating and physical structure on benthic cover and fish communities
The hypothesis that thermal discharge decreases benthic cover, fish richness and diversity but physical structure, when coupled with high diversity and abundant benthics cover, minimised thermal effects on fish communities is supported.
Distribution and size of the mojarra Diapterus rhombeus (Cuvier) (Actinopterygii, Gerreidae) in a Southeastern Brazilian bay
Distinct size classes occupying different bay zones suggest that the age-groups optimize their coexistence by partitioning the available resources, avoiding intra-specific competition.
Patterns of spatial distribution of five species of mojarras (Actinopterygii: Gerreidae) in a small tropical estuary in south-eastern Brazil
Spatial partition seems to be the strategy developed by the 5 members of theGerreidae family to coexist in the Mambucaba estuary, which may be attributed to competition in the past between the species of Gerreidae or to differentiated tolerance to environmental constraints.
Effects of a nuclear power plant thermal discharge on habitat complexity and fish community structure in Ilha Grande Bay, Brazil.
Habitat indicators and fish communities exhibited significant differences between the impacted and control locations, with the impacted one showing a significant decrease in fish species richness and diversity, as well as a decrease in benthic cover.
Sustained mass coral bleaching (2016–2017) in Brazilian turbid-zone reefs: taxonomic, cross-shelf and habitat-related trends
Between 2014 and 2017, an unprecedented heat stress accumulated and propagated across the tropical oceans and resulted in the so-called Third Global Bleaching Event (TGBE). Information about the
Hierarchizing biological, physical and anthropogenic factors influencing the structure of fish assemblages along tropical rocky shores in Brazil
Understanding the distribution patterns of reef fish and the relationships between those patterns and habitat and anthropogenic factors is important for the development of conservation policies by
Fish assemblage structure on sandy beaches with different anthropogenic influences and proximity of spawning grounds
The high fish richness and abundance and the more conspicuous species turnover across seasons on the insular beach are probable indications of more complex and dynamic organization of the communities favored by better geographical position and less anthropogenic disturbance in the area.
Length–weight relationships of 23 fish species from Southeastern Brazil
This study presents the first estimation of LWR for two species (Ctenogobius stomatus and CtenogOBius boleosoma) and new maximum length records were obtained for twospecies.
The use of the Guaratiba magrove, Sepetiba Bay, Rio de Janeiro, by the silverside Atherinella brasiliensis (Quoy & Gaimard) (Atheriniformes, Atherinopsidae)
The affinity for highly structured habitats in mangrove and the capacity to use efficiently semi-closed systems was confirmed for A. brasiliensis in Guaratiba mangroves.
