The role of salinity in structuring the fish assemblages in a tropical estuary
In the Caete estuary seasonal salinity fluctuations appeared to be the main factor that structured the fish assemblage in the entire estuarine system.
Fish Communities in Central Amazonian White- and Blackwater Floodplains
In Amazonian floodplains, the flood cycle of the river is becoming the dominant seasonal factor, and fish communities are found to fluctuate greatly over the year. During inundation, fish migrate…
Seasonal changes in density, biomass, and diversity of estuarine fishes in tidal mangrove creeks of the lower Caeté Estuary (northern Brazilian coast, east Amazon)
The abundance-biomass comparison plots for the fish fauna in the creeks of the Furo do Meio showed that the dominant species increased in number and weight at the beginning of the rainy season and Hill's index of diversity declined, whereas the number of species and evenness did not change.
Population structure, catch composition and CPUE of the artisanally harvested mangrove crab Ucides cordatus (Ocypodidae) in the Caeté estuary, North Brazil: Indications for overfishing?
The results suggest that the economic and social sustainability of this fishery will be affected well before the biological one, which should be considered in the recently proposed coastal co-management plan for the region.
Structure and Seasonal Dynamics of Larval Fish in the Caeté River Estuary in North Brazil
Larval density peaked in the upper estuary during the dry season and was lowest when freshwater discharge was at its maximum, which was attributed to an increased seaward drift of larvae.
Effect of increased irradiance and thermal stress on the symbiosis of Symbiodinium microadriaticum and Tridacna gigas
Community structure and temporal variability of ichthyoplankton in North Brazilian mangrove creeks
The species composition and dynamics of fish larvae in three mangrove creeks located in the Caete Estuary (north Brazil) were studied monthly using a trap net during diurnal ebb tides, indicating continuous transport out of the mangroves by tidal currents.
Sequence divergence of mitochondrial DNA indicates cryptic biodiversity in Octopus vulgaris and supports the taxonomic distinctiveness of Octopus mimus (Cephalopoda: Octopodidae)
Based on the mtCOIII gene tree the existence of cryptic species among O.’vulgaris-like octopods is suggested and the treatment of O’mimus as a species distinct from Mediterranean O.mimus is supported by a high nucleotide divergence of 12.7%.

Tidal behaviour strategies are described for fish species that linger in the mangrove forest during low tide forFish densities were not significantly different among areas and between months, although, total biomass differed significantly in time and space.
