Revealing the drivers of taxonomic and functional diversity of nearshore fish assemblages: Implications for conservation priorities

Diversity and Distributions, Volume 28, Issue 8, Page 1597-1609, August 2022., 2022
Abstract Aim Understanding patterns and drivers of biodiversity are essential towards developing effective conservation strategies for shallow marine habitats broadly. However, little is known about the natural and anthropogenic factors that structure fish biodiversity of sandy beaches, one of the largest and most socio‐economically valuable nearshore ...

Carbon primary sources and estuarine habitat use by two congeneric ariid catfishes in a subtropical coastal lagoon

Zoologia (Curitiba), 2016
Although ariid catfishe species are known to use coastal systems during some stages of their life cycles, the energetic contribution of estuarine resources and habitat use by many species in this family are still unclear.

Temporal variation in composition, abundance and biomass of the fish fauna after impact on subtropical transitional water

Acta Scientiarum: Biological Sciences, 2023
Transitional waters are characterized by large variations in salinity, temperature, turbidity, among other factors, such as tidal cycle, wind action and rainfall, that are constantly changing over time. The distribution of biota in these environments is
