“…The exception was Euterpe edulis, a dominant palm species in undisturbed areas of the Atlantic forest (Guilherme et al 2004), which, contrary to our expectations, was among the most abundant species in all pathways. Possibly, the high survival rates of juvenile in gaps, compared to areas with dense canopy cover, may explain this unexpected pattern (Nakazono et al 2001;Ribeiro et al 2011b).…”

Although impacts generated by gaps can aff ect vegetation, few studies have addressed these impacts in the Atlantic Forest. Our aim was to investigate the eff ects of pathways of varying widths on vegetation structure and composition, considering dispersal syndromes, diversity, life forms, successional categories and threatened and exotic species occurrence in the Atlantic Forest. We studied three pathways with widths of 2, 10 and 20 m, intersecting a protected area in southeastern Brazil. To assess edge eff ects, plots were established adjacent to paths (edge) and 35 m from the edge (neighborhood), and in a control area without pathways. Wider pathways (10 and 20 m) exhibited reduced tree height and diameter, high liana density, exotic species, and a high proportion of pioneer and anemochorous species. In conclusion, our results indicate that the vegetation structure of narrow pathways (2 m) is similar to the control area, and that wide linear gaps cause negative eff ects on vegetation and extend to a distance of at least 35 m into the forest interior. Considering that linear gaps generate permanent eff ects to vegetation and may aff ect other organisms, we suggest that these eff ects must be considered for successful management of protected areas, including planning and impact mitigation.

RESUMO -o objetivo deste trabalho foi avaliar o efeito do sombreamento e de métodos de propagação na morfoanatomia foliar e no estabelecimento de cupuaçuzeiros. o experimento foi realizado a campo, em blocos casualizados, com quatro repetições de 10 plantas cada. Para análise de crescimento, utilizou-se do esquema de parcelas subsubdivididas (cinco épocas -parcela; três níveis de sombreamento -subparcela, e quatro métodos de propagação -subsubparcela). Para a avaliação da biometria das plantas, utilizou-se do esquema de parcela subdivida com os sombreamentos na parcela e os métodos de propagação nas subparcelas; e para as análises morfoanatômicas, considerou-se a casualização do sombreamento nos blocos. as análises de crescimento foram realizadas a cada 90 dias; e as morfoanatômicas, aos 15 meses após o plantio. a espessura do parênquima esponjoso foi maior nas folhas sombreadas por tela de 50%, as outras características morfoanatômicas não sofreram influência significativa dos níveis de sombreamento. as mudas com desenvolvimento inicial em viveiro atingiram maior taxa de crescimento relativo e absoluto. as maiores taxas de crescimento relativo e absoluto foram obtidas em cultivo sob tela de 50% de sombreamento, seguido pelo consórcio (45% de sombreamento). os piores desempenhos em todas as características avaliadas foram observados em plantas cultivadas a pleno sol.

MORPHOANATOMY LEAF OF CUPUASSU PLANT ESTABLISHED FOR DIFERENT METHODS OF SPREAD AND SHADOWINGABSTRACT -The objective of this study was to evaluate the effect of shadowing and propagation methods in morphoanatomy and establishing cupuassu. The field experiment was conducted in a randomized complete block design with four replications of 10 plants each. For growth analysis was used to plot subdivided (five times -plot, three levels of shading -subplot and four methods of propagation -sub -subplots). For evaluation of biometrics plant was used scheme subdivides plot with shading in the plot and subplots propagation methods; and the analysis morphoanatomic considered the randomization in blocks of shading. analyses of growth were performed every 90 days and morphoanatomical at 15 months after planting. The thickness of the spongy parenchyma was higher in shaded leaves by 50 % screen; other features morphoanatomic suffered no significant influence of shading levels. Seedlings with initial development in nurseries reached higher relative growth rate and absolute. The highest relative growth rates and absolute were obtained in culture under 50 % screen, followed by the consortium (45 %). The worst performers in all traits were observed in plants grown in full sun.

“…No difference in the percentage of propagule germination was found for this species at various levels of shading (Tavares, Ramos, Aguiar, & Kanashiro, 2008). Although the survival of E. edulis seedling was higher in areas with greater canopy openness and brighter, the light levels no influenced the height growth of this species (Ribeiro, Martins, Lana, & Silva, 2011). Fruit predation, because of its attractiveness, especially for avifauna (Cavalheiro, 2006), would result in reduced fruit number and therefore less seedling.…”

ABSTRACT. Different species of plants can act as environmental filters affecting the composition, structure and spatial distribution of seeds and seedlings of forest species. This study aimed to examine whether the presence of the fern stratum acts as a biotic environmental filter on the woody species seedling bank in a semi-deciduous forest remnant (Atlantic biome), Southern Brazil. Two experiments were developed in areas with ferns (F) and ferns-free (NF): a) richness and abundance of woody seedling bank were determined in 10 plots (25 m 2 ) in each area; b) seedlings abundance of Actinostemon concolor (Spreng.) Müll. Arg., Aspidosperma polyneuron Müll. Arg., Euterpe edulis Mart., Guarea kunthiana A. Juss. and Inga marginata Kunth were monitored for a year in three areas F, NF and an area with ferns whose fronds were cut (CF). In this experiment, it was used five plots (4 m 2 ) in each area. The abundance of seedlings (considering all species) was higher in F areas and ferns positively and negatively affected the abundance of A. polyneuron and G. kunthiana, respectively. It is possible to conclude that ferns worked as a selective environmental filter for some woody species.
