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 environmentalExpand

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 influence of a nuclear power plant’s cooling water and physical structure on benthic cover and fish communities were assessed in a coastal area in Southeastern Brazil. We hypothesised thatExpand

Distribution of guppies Poecilia reticulata (Peters, 1860) and Phalloceros caudimaculatus (Hensel, 1868) along a polluted stretch of the Paraíba do Sul River, Brazil.
Cyprinodontiformes fishes (guppies) are widely distributed in Neotropical regions and use deteriorated microhabitats in rivers where few species can occur. This study was carried out in a stretch ofExpand

Shifts in the abundance and distribution of shallow water fish fauna on the southeastern Brazilian coast: a response to climate change
The temperature in the South Atlantic underwent an increase from 1948 to 2016, and the Brazilian coast is very likely suffering from climate change. We examined temporal shifts in the abundance ofExpand

Fish composition and assemblage structure in the estuarine mixing zone of a tropical estuary: comparisons between the main channel and an adjacent lagoon
Abstract Spatial patterns of an estuarine habitat used by fish assemblages were determined for a protected adjacent lagoon and two areas of the main estuarine channel in a small tropical estuary. TheExpand
