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.

SummaryIn the zooplankton collected during three German Antarctic expeditions to the southern Weddell Sea in 1979/80, 1980/81 and 1983, the post-larvae of the nototheniid fish Pleuragramma
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.
The early life-history of the high-Antarctic silverfish, Pleuragramma antarcticum
During the German Antarctic expeditions of 1979–1980 and 1980–1981 plankton and fish fry were collected quantitatively in the eastern and southern Weddell Sea, it is shown that Pleuragramma antarcticum larvae co-occurred frequently with larval channichthyids which preyed on them.
Seasonal Patterns of Ichthyoplankton Distribution and Abundance in the Southern Weddell Sea
Spatial and temporal distribution patterns of the most abundant taxa were interpreted as adaptations in the life history to extend the geographical basis of the larval drift beyond the limited continental shelf area.
Age and growth of Antarctic Silverfish Pleuragramma antarcticum Boulenger, 1902, from the southern Weddell Sea and Antarctic Peninsula
In spite of low “k”, Pleuragramma antarcticum does not grow to large size and is discussed in the light of adaptive demands of the species as a planktivorous pelagic nototheniid in the Antarctic.
Ecology of Notothenioid Fish in the Weddell Sea
Hydrography becomes a critical factor when pelagic stages are included in the life history and environmental factors such as water-mass distribution and current patterns also affect the life of fish in the Antarctic.
The fish fauna of the Ross Sea, Antarctica
The RV Nathaniel B. Palmer was used for bottom trawling at depths of 100–1200 m during two recent cruises in the south-western Ross Sea. Although only 10 of 20 trawls were completely successful, a
Zooplankton biomass in the ice-covered Weddell Sea, Antarctica
The data reveal that it is essential to distinguish among subsystems in the Southern Ocean, which leads to a better understanding of the structure and function of those pelagic food webs which represent alternatives to the paradigmatic krill-centered system.
