Composition and intra-annual variation of the macroinfauna in the estuarine zone of the Pando Stream (Uruguay)
We studied the temporal patterns of macroinfaunal distribution in the estuarine portion of Pando Stream, Uruguay. We found a very low number of species and a high dominance of the polychaete Heteromastus similis. There were clear seasonal patterns in abundance with almost all species peaking in autumn, coinciding with the periods of higher salinity. Minimal values were found in winter and spring when salinity was at a minimum. We suggest that the seasonal pattern is a consequence of the combined effects of recruitment, and of high osmotic stress and disturbance during the periods of freshwater discharge that are common in winter and spring.
