“…However, a number of surveys that sampled woody plants or trees did not record different densities of individuals in treefall gaps and control understorey plots (Arévalo & Fernández-Palácio 1998, Tabarelli & Mantovani 1998, Carvalho et al 2000, Dickinson et al 2000. The present study generated similar results, in terms of both the whole plant community, including all growth habits and tree species alone.…”

“…Only three species occurred preferentially in treefall gaps in this survey (Evodianthus funifer, Pouroma mollis, and Protium heptaphyllum). Numerous studies have demonstrated the lack of significant differences between plant communities in treefall gaps and in the nearby understorey vegetation (Barton 1984, Brokaw & Scheiner 1989, Arévalo & Fernández-Palácio 1998, Tabarelli & Mantovani 1998, Carvalho et al 2000, Dickinson et al 2000.…”

“…Some authors had suggested that large gaps -greater than 400 m 2 (Denslow 1987) or 1.000 m 2 (Hartshorn, 1978) -are required to the establishment of pioneer species or large gap specialists (Denslow 1980). However, in previous studies carried on sites that are not usually exposed to large disturbances such as hurricanes or cyclones, the largest gaps sampled were less than 400 m 2 (Abe et al 1995, Midgley et al 1995, Arévalo & Fernandez-Palácio 1998, Carvalho et al 2000 and gaps with more than 120 or 150 m 2 were considered large (Yavitt et al 1995, Dickinson et al 2000, Tabarelli & Mantovani 2000. In the present study, all gaps were less than 400 m 2 , but they represent the largest gaps in this forest and all but one were greater than 120 m 2 .…”

-(Community structure of vascular plants in treefall gaps and fire-disturbed habitats in the Atlantic rainforest, southern Bahia, Brazil). The effects of disturbances on plant community structure in tropical forests have been widely investigated. However, a majority of these studies examined only woody species, principally trees, whereas the effects of disturbances on the whole assemblage of vascular plants remain largely unexplored. At the present study, all vascular plants < 5m tall were surveyed in four habitats: natural treefall gaps, burned forest, and their adjacent understorey. The burned area differed from the other habitats in terms of species composition. However, species richness and plant density did not differ between burned area and the adjacent understorey, which is in accordance to the succession model that predict a rapid recovery of species richness, but with a different species composition in areas under moderate disturbance. The treefall gaps and the two areas of understorey did not differ among themselves in terms of the number of individuals, number of species, nor in species composition. The absence of differences between the vegetation in treefall gaps and in understorey areas seems to be in agreement with the current idea that the species present in treefall gaps are directly related to the vegetation composition before gap formation. Only minimal differences were observed between the analyses that considered only tree species and those that considered all growth habits. This suggests that the same processes acting on tree species (the best studied group of plants in tropical forests) are also acting on the whole assemblage of vascular plants in these communities.Key words -atlantic forest, fire, growth habits, natural treefall gaps, species richness RESUMO -(Estrutura da comunidade de plantas vasculares em clareiras naturais e em área perturbada por fogo em uma floresta pluvial tropical Atlântica no Sul da Bahia, Brasil). Os efeitos das perturbações sobre parâmetros da estrutura de comunidade de plantas em florestas tropicais têm sido freqüentemente analisados. Porém, a maioria dos estudos realizados até o momento tem considerado somente plantas lenhosas, principalmente árvores, e o efeito de perturbações sobre toda a comunidade de plantas vasculares ainda não havia sido avaliado. No presente estudo, todas as plantas vasculares menores que 5 metros de altura foram amostradas em clareiras naturais, em uma área de floresta queimada em um incêndio acidental e em áreas de sub-bosque adjacentes. A área queimada diferiu das outras áreas em relação à composição de espécies, porém a riqueza de espécies e a densidade de indivíduos não foi diferente entre a área queimada e as áreas de sub-bosque. Estes resultados estão de acordo com os modelos sucessionais que prevêem que em locais sujeitos a perturbações de intensidade moderada ocorre uma rápida recuperação da riqueza de espécies, porém com uma composição de espécies diferenciada. As clareiras naturais e as áreas de sub-bosque não difer...

“…Increases in shade intolerant species have been associated with increased logging intensity indicating these species preference to more open and intensively logged habitats (Hawthorne, 1993;Dickinson et al, 2000). However, increased numbers of juveniles of both shade tolerant and intolerant species following logging has been recorded.…”

We examined tree diameter growth in 20 plots subjected to various disturbance intensities (natural, low, moderate and intensive logging) in a bid to understand the general tree growth responses in relation to habitat characteristics in subtropical rainforests of north-eastern New South Wales, Australia. Species-specific regeneration strategy, maximum size and level of shade tolerance were used to classify species into 5 groups; emergent and shade tolerant main canopy (group 1), shade tolerant mid canopy (2), shade tolerant understoreys (3), moderate shade tolerant (4), and shade intolerant (5) tree species. Data series for trees ≥ 10 cm diameter at 1.3 m above the ground level (dbh) providing observations spanning over 36-years were used in multilevel regression analyses. The results showed that spatial and temporal effects in tree growth at the stand-level are a combination of the differences between species functional-group compositions and environmental gradients. High growth responses were observed in the shade intolerant species while increasing level of shade tolerance and decreasing maximum size decreased trees growth rates. Tree growth increased with altitude on a large scale across regions, and with disturbance intensity on a small scale at the plot (stand) level. Increase in northness (south through flat to north facing sites) increased growth in species group 1 for trees < 67 cm dbh, but beyond this dbh threshold the opposite was true. These showed that saplings of species group 1 may require increased illumination to reach the forest canopy, but once in the canopy, low soil water availability may be limiting to tree growth in the north facing sites. Decrease in northness was associated with increased growth in species group 2 indicating that reduced illumination and improved soil moisture in the south facing sites were conducive for maximum growth in this species group. Maximum growth potential in species group 4 and 5 increased with decrease in eastness, suggesting that the increased afternoon solar radiation and temperature were conducive for high growth rates in these species. Although topographic gradient may determine the spatial and temporal variations in tree growth where growth appeared to increase from the crest down the slope into the creek, its effects on soil fertility and water availability, and interactions between these and other factors may make it difficult to discern clear growth patterns.
