Feeding behavior of juveniles of the planktonic shrimp Lucifer faxoni Borradaile was studied in the laboratory under light and dark conditions. Newly-hatched nauplii and metanauplii of Artemio were used as prey organisms. The fecding raie of L. foxoni was dependent on prey size and prey density, but was not obviously affected by light or dark conditions. The capture of the prey tended to increase with longer exposure time to prey. The maximum ingestion rate was 17.28 and 13.40 nauplii.L. faxoni ...

Based on a compilation of data on massive fish deaths occurred in southern South America during the Twentieth Century, we assessed the importance of climatic variables on these phenomena. We found a strong relationship (R² =0.68) between these massive fish deaths and the mean monthly air temperature. Along the annual temperature range there is a central range (14.6° C to 20.0° C), where the probabilities that a fish community suffers massive deaths is very low. Its central point (17.3° C) is ver...

<p>Sand dunes and other active sands generally have a low content of fine grains and, therefore, are not considered to be major dust sources in current climate models. However, recent remote sensing studies have indicated that a surprisingly large fraction of dust storms are generated from regions covered by sand dunes, leading these studies to propose that sand dunes might be globally relevant sources of dust. To help understand dust emissions from sand dunes and other active sands, we present ...
