| Metamysidopsis elongata atlantica (Bacescu, 1968) was reared in the laboratory for 45 days at 20±1°C and salinity of 30ppt. Growth curves (von Bertalanffy model) were calculated for both sexes and for each sex. The daily rate of carapace growth was significantly different between females and males (F test, p <0.05). Before the sexual maturity (14 days), the growth rate of females was higher than that of males (females, 0.0457 mm day-1; males, 0.0448 mm day-1). After the maturity (15 to 45 days), these rates decreased similarly for both sexes (females, 0.0203 mm day-1; males, 0.0174mm day-1). The average growth rate was 0.0207mm day-1 over the 45 days. Twelve molts were observed in a period of 60 days. The first five molts occurred up to 14 days old (age... |

| The individuais of Charadriifonnes present plumages of either young, or adults; adults in turn, present plumages of either reproduction, ar intermediate. Aiming to monitor plumages and molts, and associating them to migrations, specimens were collected on the coast of Pernambuco State, in the Coroa do Avião, Santa Cruz channel (7º40'S e 34º 50'W). Plumages of young, non-breeding adults, intermediate adults, and breeding adults were recorded amongst the specimens captured. The molt cicle of primary remiges indicates that individuals initiating molts in June and July will not return to their areas of reproduction, and that the ones who start from August to October, ending till February, will migrate in the same year to their breeding grounds. Retrix molts... |
