“…Th e number of rare species (i.e. singletons) per hectare represented 17% of the plot richness, a value quite similar to other HRFs (14 to 17%, Assis et al 2004;Negrelle 2006) and lower than that observed values for forests on non-sandy soils (> 23% - Melo 2000Guilherme et al 2004;Losos 2004). In addition, Fisher´s alpha were much smaller than in 10 other tropical forest plots (values from 23 to 181) evaluated by Condit et al (2004), except by the Mudumalai dry deciduous forest plot (5.9).…”

“…Exceptions are found where there is illegal palm-heart harvesting (César & Monteiro 1995;Guilherme et al 2004;Guedes et al 2006), an activity not seen inside the plot. Myrtaceae also deserves special mention because it harbored twice as many species as the second richest family of the plot.…”

“…Th is pattern was not observed in other CTFS plots (Ashton et al 2004), or inventories of forests on white-sand soils in South America (Phillips & Miller 2002) and Asia (Proctor et al 1983;Newbery 1991;Davies & Becker 1996), where Myrtaceae does not exceed 7% of the total tree richness. However, nearby Atlantic Forest types have similar richness per family, with similar or higher Myrtaceae richness Guilherme et al 2004), suggesting an important eff ect of the geographic region on the general pattern of HRF fl oristic composition.…”

RESUMO(Estrutura, diversidade e padrões espaciais em uma parcela permanente de fl oresta alta de Restinga no Sudeste do Brasil) Nós investigamos a estrutura, diversidade e distribuição de espécies arbóreas em uma parcela de 10,24 ha de uma fl oresta alta de Restinga (FAR) ). A riqueza média foi menor que outros tipos de fl orestas tropicais e outras FAR amostradas em menor intensidade, provavelmente pela juventude e hidromorfi a dos solos na área de estudo. A densidade, área basal, composição e diversidade arbórea variaram consideravelmente de acordo com a classe de tamanho considerada. A parcela estudada teve uma densidade similar a outras fl orestas tropicais, mas com menor área basal (menos indivíduos > 60 cm de diâmetro) e maior densidade de árvores pequenas. Fustes múltiplos não foram frequentes (11% dos indivíduos), mas foram comuns entre as espécies (74% das espécies). A distribuição espacial foi predominantemente agregada, um padrão comum a outros tipos de fl orestas tropicais. Além do substrato arenoso, a parcela estudada e outras fl orestas de areia branca do mundo tiveram padrões muito similares de estrutura, riqueza e diversidade. Assim, consideramos a FAR como um subtipo evidente de fl oresta de areia branca. Palavras ABSTRACT(Structure, composition, and diversity of a high Restinga forest in the Southern Atlantic Forest) We assessed the structure, diversity and distribution of tree species in a 10.24-ha permanent plot of high Restinga forest (HRF) in southeastern Brazil. We sampled 15,040 individuals belonging to 45 families, 87 genera and 116 species (density= 1,468 trees ha -1 , and basal area= 28.0 m 2 ha -1 ). Mean richness was lower than other types of tropical forests and other HRFs that have been less intensively sampled, which is probably due to the younger age and hydromorphy of the soils in the study site. Tree density, basal area, species composition, and diversity all varied considerably depending on the size class considered. The studied plot had a density similar to other tropical forests but with a smaller basal area (fewer individuals > 60 cm in diameter), and higher density of smaller trees. Multi-stemmed individuals were not frequent (11% of the trees), though they were widespread among species (74% of the species). Spatial distribution was predominantly clumped, a pattern common to other types of tropical forests. Besides growing over white-sand soils, the PEIC plot and other white-sand forests of the world also had very similar patterns of community structure, richness and diversity. Therefore, we consider the HRF as a recognizable subtype of white-sand forest.

“…Nos estádios iniciais há maior densidade de árvores, o que pode ser modificado rapidamente nos primeiros anos de sucessão (Finegan 1996). Com o aumento da idade das florestas, a estratificação vertical torna-se mais evidente, aumentando a complexidade estrutural da comunidade (Tabarelli & Mantovani 1999a;Guilherme et al 2004;.…”

RESUMO -(Florística e estrutura de comunidades vegetais em uma cronoseqüência de Floresta Atlântica no Estado do Paraná, Brasil). Descrevemos a estrutura do estrato arbóreo de três sítios de Floresta Atlântica no litoral do Paraná, objetivando detectar diferenças estruturais gerais e nas populações ao longo do processo sucessional, visando subsidiar futuros planos de recomposição da vegetação. O estudo foi realizado na Reserva Natural Rio Cachoeira, onde foram escolhidos três sítios, cujos históricos indicavam a ocorrência de corte da vegetação há 20 anos, 80 anos e 120 anos. O sítio com 20 anos apresentou os menores valores de riqueza, diversidade, área basal e volume. O sítio com 80 anos apresentou os maiores valores de densidade e riqueza. No sítio com 120 anos foi observado o maior valor de diversidade, equabilidade e volume. Observaram-se algumas diferenças significativas, em termos de diversidade, área basal e volume entre os sítios em diferentes estádios. Comparações das estruturas de populações de espécies que ocorriam em mais de um sítio não mostraram grandes diferenças. Por outro lado, as características das espécies exclusivas de cada sítio influenciaram nas diferenças observadas nos três sítios. Palavras-chave: sucessão secundária, biodiversidade, floresta tropical, conservaçãoABSTRACT -(Floristics and structure of plant communities along a chronosequence in the Atlantic Rain Forest of Paraná State, Brazil). We describe the tree structure of three Atlantic Forest fragments on the coast of Paraná, in order to detect differences in community structure throughout the succession process and to support future vegetation restoration projects. The study area was the Reserva Natural Rio Cachoeira, where three sites were chosen based on length of time since the last manmade disturbance (mostly agriculture and lodging); these were, respectively, 20-, 80-and 120-year-old forests. The 20-year-old forest had the lowest richness, diversity, basal area and volume. The 80-year-old forest had the highest density and richness. The 120-year-old forest had the highest diversity, equitability and volume. Diversity, basal area and volume were significantly different among the three sites. There were no important differences among structures of populations of species shared by the three areas. On the other hand, structural characteristics of exclusive species were important to determine differences among sites.

ABSTRACT(Altitudinal heterogeneity in northern Atlantic Forest: a case study in southeastern Bahia, Brazil) Th e Atlantic Forest has a heterogeneity that is still largely unappreciated, especially that associated with altitudinal factors; this has rarely been examined in the northern extension of this biome. Th e study investigated the occurrence of variation in fl oristic composition, diversity, and vegetation structure at two altitudes in a remnant area of forest in southern Bahia state. A total of 0.5 ha of vegetation was sampled in fi ve separate plots established in a wet forest in the RPPN Serra Bonita, Bahia, Brazil. A total of 354 species belonging to 68 families were found, with Myrtaceae, Fabaceae, Rubiaceae and Lauraceae being the richest taxa. Th e two altitudinal sites showed signifi cant diff erences in density, basal area and structure. Th ere were notable changes in forest structure with increasing altitude, refl ected in higher densities of the understory and a reduction in species richness. Serra Bonita had high species diversity that was similar to other areas in Bahia, but higher than found in the Atlantic Forests of southeastern Brazil. Th e forest sections sampled were well preserved, as indicated by the abundance of woody vines, elevated basal area, and lack of evidence of signifi cant logging activities. Th e variation detected between the areas suggests the existence of abrupt structural modifi cations infl uenced not by edaphic factors but by rainfall diff erences, temperature variations, and by local barriers determined by the steep topography.
