Resumo: A regeneração consiste no processo de reconstrução e reorganização da composição e estrutura de uma comunidade vegetal, e vem sendo bem estudada em florestas ombrofilas e estacionais sob a ótica da dinâmica de clareiras e da sucessão ecológica. No entanto, a regeneração de espécies lenhosas no cerrado ainda e pouco compreendida, e são poucos os estudos que avaliam conjuntamente o dossel e o sub-bosque em áreas de cerrado. O objetivo deste trabalho foi avaliar a floristica e a fitossociologia da comunidade lenhosa do dossel e do sub-bosque de um cerradão em Assis, SP. O trabalho foi realizado na Estação Ecológica de Assis, em uma parcela permanente de 10,4 ha, parte do "Projeto Parcelas Permanentes" do Programa BIOTA/FAPESP. Essa parcela permanente e subdividida em 256 subparcelas contiguas de 20 m x 20 m, das quais 100 foram sorteadas para amostragem. Para avaliar o dossel, foram considerados os dados já coletados no Projeto Parcelas Permanentes, referentes aos indivíduos lenhosos com perímetro na altura do peito (PAP) ? 15 cm, para as 100 subparcelas sorteadas. Para analisar o sub-bosque, foi delimitado um setor de avaliação de 2 m x 2 m em cada subparcela sorteada, onde foram medidos e identificados todos os indivíduos de espécies lenhosas com altura > 20 cm e PAP < 15 cm. Todas as espécies do dossel e do sub-bosque foram classificadas de acordo com o habitat, com base em estudos regionais de fitossociologia, em categorias não excludentes: floresta (F), quando ha registro da espécie em formações florestais não pertencentes ao cerrado sensu lato; cerradão (C), quando ha registro da espécie em cerradão; e cerrado sensu lato (c), quando ha registro da espécie nas demais fisionomias de cerrado sensu lato. Alem disso, foram calculados os parâmetros fitossociologicos usuais para todas as espécies no dossel e no sub-bosque. Tanto o dossel quanto o sub-bosque do cerradão em Assis foram compostos por espécies intermediarias entre diferentes habitats, a maior parte (46% das espécies no dossel e 36% no sub-bosque) constituída de espécies de cerrado/cerradão, incluindo espécies de ampla distribuição no domínio (como Bowdichia virgilioides, Machaerium acutifolium, Plathymenia reticulata, Pouteria ramiflora, Qualea grandiflora, Roupala montana e Xylopia aromática) e comuns em cerrados da província Meridional (como Eriotheca gracilipes, Eugenia pluriflora, Gochnatia polymorpha, Machaerium brasiliense, Myrcia venulosa e Ocotea corymbosa). Regenerantes das espécies do dossel constituíram a maior parte do sub-bosque do cerradão, tanto em numero de espécies (81% do total, n=60) quanto em valor de importância (221 do total de 300). O cerradão apresentou um conjunto de espécies de sub-bosque composto por arvores de pequeno porte e arbustos heliofitos que também ocorrem nas fisionomias mais abertas de cerrado, incluindo: Lacistema hasslerianum, Miconia albicans, Miconia langsdorffii, Miconia stenostachya, Palicourea marcgravii, Piptocarpha rotundifolia, Psychotria hoffmannseggiana e Psychotria vellosiana. Esse resultado e consistente com as características estruturais do dossel do cerradão, que possibilitam maior entrada de luz ao sub-bosque; e contrasta com o relatado para outras fisionomias florestais, onde as espécies de sub-bosque são tipicamente tolerantes a sombra
Abstract: Regeneration consists on the process of reconstruction and reorganization of the structure and composition of a plant community, and has been intensively studied in ombrophilous and seasonal forests according to the paradigm of gap dynamics and ecological succession. However, regeneration of woody plant species in the cerrado is still poorly understood, and few studies evaluate both the overstory and the understory in cerrado areas. The aim of this study was to investigate the floristics and phytosociology of the woody community of the overstory and understory in a cerradao fragment at Assis, Sao Paulo State, southeastern Brazil. Field work was conducted at Assis Ecological Station, in a 10,4 ha permanent plot, part of the Permanent Plots Project from the BIOTA/FAPESP Program. This plot is divided in 256 contiguous subplots of 20 m x 20 m, of which 100 subplots were randomly selected and analyzed. To study the overstory, we used data collected at the Permanent Plots Project, regarding all woody individuals with perimeter at breast height (PBH) ? 15 cm, for these 100 subplots. To study of the understory, we delimited a sector of 2 m x 2 m within each selected subplot, in which all woody individuals with height > 20 cm and PBH < 15 cm were measured and identified. All overstory and understory species were categorized according to their habitat, based in regional phytosociological studies, into non excluding groups: forest (F), when there is record of the species in forest formations that do not belong to cerrado sensu lato; cerradao (C), when there is record of the species in cerradao; and cerrado sensu lato (c), when there is record of the species in the remaining cerrado sensu lato physiognomies. We also calculated the usual phytosociological parameters for all overstory and understory species. Both the overstory and the understory in the study site were composed of species of intermediate distribution between habitats, the majority (46% of overstory species and 36% of understory species) occurring in cerrado/cerradão, including widely distributed Cerrado species (such as Bowdichia virgilioides, Machaerium acutifolium, Plathymenia reticulata, Pouteria ramiflora, Qualea grandiflora, Roupala montana e Xylopia aromatica) and common southern Cerrado species (such as Eriotheca gracilipes, Eugenia pluriflora, Gochnatia polymorpha, Machaerium brasiliense, Myrcia venulosa e Ocotea corymbosa). Regenerating individuals belonging to overstory species accounted for most of the cerradão understory, both in number of species (81%, n=60) and importance value (221 of the total of 300). At the cerradão, we observed a group of understory species composed of heliophyte and small sized trees and shrubs that also occur in the open cerrado physiognomies, such as: Lacistema hasslerianum, Miconia albicans, Miconia langsdorffii, Miconia stenostachya, Palicourea marcgravii, Piptocarpha rotundifolia, Psychotria hoffmannseggiana e Psychotria vellosiana. This result is consistent with the structural characteristics of the cerradão overstory, which enable light penetration to the understory; and differs from data reported in other forest formations, where understory species are typically shade tolerant
