| The crustaeeans of Aeglidae family oeeur in South America's fresh water enviranments, featuring as important links in the food chains. The present article has the intention to give an acount of the results from investigations made from April/2000 to July/2001 on the biological and ecological features of Aegla leptodactyla Buckup & Rossi, 1977, an endemic species from the headwaters of the Rio Pelotas Basin in Rio Grande do Sul State, Brazil. The sampling was performed at the Rio da Divisa, tributary of Rio Pelotas, municipal district of São José dos Ausentes, Rio Grande do Sul. The animais were collected with a hand net (puçá) at four different sites of the river. High contents of dissolved oxygen was verified, with a medium value of 108% and alow... |

| The growth study, in length and weight, of Aegla leptodactyla Buckup & Rossi, 1977, was developed based on biometric data of 2,435 specimens collected from Rio da Divisa, a tributary of the Rio Silveira, district of São José dos Ausentes, Rio Grande do Sul State, Brazil. The samplings were realized from April/2000 to July/2001. The captured specimens had recorded the Sex and the length and width of cephalothorax. The specimens from June/2000, November and May/2001 were weighted, and those from June and July/2001 had recorded their length and width of the chelipeds. For the description of the growth the von Bertalanffy's model was utilized. The growth curves in length (mm), for data obtained through the modal progression, are described by the... |
