Resumo: | http://dx.doi.org/10.5902/1980509812352Semideciduous forests occur in a few places in the Cerrado biome, but are being suppressed through byagriculture and livestock in central Brazil. The objective of this study was characterize the horizontaland vertical structures, the dispersal syndromes, successional groups and floristic similarity of the treelayer and regeneration in a semideciduous forest fragment in Itumbiara, Goiás state. All trees alive withcircumference at breast height (CAP) ≥ 15 were identified and measured for height and diameter in 25 plotsof 20 x 20 m. To the regenerative stratum the criteria was the inclusion of individuals with height ≥ 1m untilCAP = 14.9 cm in 25 plots of 10 × 10 m. In both layers were sampled 100 species. The species with thehighest importance in the tree layer were Nectandra megapotamica (Spreng.) Mez, and in the regenerativestratum, Siparuna guianensis Aubl. Both layers had a higher proportion of early secondary species and thezoochory dispersion syndrome was more frequent. Several important species are not represented in othersemideciduous forests, and then this forest is an important permanent conservation area. |

O objetivo do trabalho foi caracterizar a estrutura horizontal e vertical, as síndromes de dispersão, os grupos sucessionais e a similaridade florística do estrato arbóreo e regenerativo de um trecho de fragmento de Floresta Estacional Semidecidual no município de Itumbiara, GO. Todos os indivíduos arbóreos vivos com circunferência do tronco a altura do peito (CAP) ≥15 foram identificados e medidos quanto à altura e circunferência do tronco em 25 parcelas de 20 x 20 m. A amostragem do estrato regenerativo foi realizada em 25 subparcelas de 10 m x 10 m, totalizando 0,25 ha, alocadas no vértice inferior direito das parcelas utilizadas para a amostragem do estrato arbóreo. Nestas subparcelas foram identificados e contados todos os indivíduos regenerantes de espécies arbóreas com altura maior ou igual a 1 m até aqueles com CAP < 15 cm. Para o estrato arbóreo foi calculados: a densidade, frequência, dominância, valor de importância e a estratificação vertical. Nos dois estratos foram amostradas 100 espécies. A espécie com maior valor de importância no estrato arbóreo foi Nectandra megapotamica (Spreng) Mez, e no estrato regenerativo Siparuna guianensis Aubl teve maior número de indivíduos. Ambos os estratos apresentaram maior proporção de espécies secundárias iniciais e a zoocoria foi a síndrome de dispersão mais frequente. A estrutura fitossociológica atual mostra que o fragmento contém diversas espécies pouco representadas em outras Florestas Semideciduais, o que mostra a sua importância como área de preservação permanente.
