| Abstract: | Females of Donax trunculus L. show higher concentrations of Mn and Zn than males. Differences are very high for Mn which also shows very large monthly fluctuations. Both the metals present higher contents during the period of gonadic maturation. Some high values of manganese found in the period when gonads are resting suggest the influence of sharp environmental variations in the area where bivalves have been collected. |
