Distribution of whitemouth croaker Micropogonias furnieri in relation to environmental factors at the Río de la Plata estuary, South America

The age-class distribution of the whitemouth croaker Micropogonias furnieri and its relationship to environmental factors was evaluated from 278 stations sampled between 1993 and 1999 during early winter and spring within the Rio de la Plata estuary (36°S, 56°W). A detrended canonical correspondence...
