Foram selecionados quatro pontos de amostragem na área do parque, sendo a coleta regular de dados realizada entre agosto de 1996 e agosto de 1997, com observações adicionais de junho a agosto de 1999 e fevereiro a outubro de 2000. Alguns fatores abióticos ( chuva, temperatura e luminosidade) interferiram na atividade reprodutiva da espécie, principalmente a precipitação. As fêmeas são maiores e mais pesadas que os machos. Os indivíduos de S. longilineus ocorrem em áreas de borda e interior de mata, mas preferencialmente nas margens de riachos no interior de mata. Um total de 322 indivíduos foram marcados, sendo 147 sub-adultos, 96 fêmeas, 67 machos e 12 imagos. Foram realizadas 69 recapturas e houve recrutamento constante durante todo o ano... / The objective of the present study was to describe the reproductive biology of the treefrog Scinax longilineus in Parque das Mangabeiras (19º 55' 57" S and 43º 56' 32" N), a reserve forest area in municipality of Belo Horizonte, State of Minas Gerais. Four sample areas were selected in the park. Field observations were realized in the period between August 1996-August 1997. Additional observations were made at the intervals of June-August 1999 -and February- October 2000. The reproductive activity of S. longilineus was influenced by some abiotic factors (rainfall, temperature, and luminosity). Females were larger and heavier than males. The individuals occurs preferentially near the streams in a forested or near forested areas. Three hundred and twenty two individuals were marked during the study. Sixty nines recaptures were realized and a constant recruitment was observed...
