The present study describes the spatial and temporal structure of the estuarine fish
community in the internal sector of the Amazon Estuary. Samples were obtained in the main …

Body size plays a key role in the functioning of communities and ecosystems. However, this
ecological trait is commonly under strong selection pressure by environmental drivers, such …

AIM: This study evaluated whether the size structure of the zooplankton community, as
analyzed from density and biomass, would be influenced by bottom-up and/or top-down …

Aquatic communities vary depending on local factors, such as environmental conditions and
biological interactions and regional factors, such as the hydrological regime in floodplains …

Aim We characterize the diet and trophic guild to the fish community in a protected area to
contribute information about the trophic ecology. Methods The collection was carried out at …

Aim We evaluated the predation interactions between Moenkhausia sanctaefilomenae and
