“…Despite variations in methods and diversity estimates among various studies (Chazdon 2008), the unidirectional increase in species richness in our study was supported even for other stem size inclusion criteria (see Appendix 2). The diversity of the late successional forest (H' canopy = 3.24) is comparable to old-growth forests (H'= 3.22-5.00) in the Atlantic Forest region (Liebsch et al 2007;Martini et al 2007;Siminski et al 2011), and suggests that 59 years of abandonment is sufficient for recovering a large part of the forest diversity and composition originally found in the study region. Despite our findings, the recovery of forest diversity is not necessarily followed by forest functionality (Díaz & Cabido 2001), which may take a longer time period and limit ecosystem processes (Liebsch et al 2008).…”

“…Patterns of changes in species richness and diversity varied across different chronosequence studies and were strongly influenced by soil fertility and land use history (Brown & Lugo 1990;Chazdon 2008). Whereas initial successional areas generally contain few tree species and low diversity (Siminski et al 2004), the peak of tree diversity might be found in intermediate (Sheil 2001;Kalacska et al 2004;Liebsch et al 2007) or in late (Saldarriaga et al 1988;Chinea 2002) phases of succession. Our results indicate an accumulation of species in the understory and the recruitment of a portion of these species to the canopy.…”

MARQUES, C.M.M., ZWIENER, V.P., RAMOS, F.M., BORGO, M., MARQUES, R. Forest structure and species composition along a successional gradient of Lowland Atlantic Forest in Southern Brazil. Biota http://dx.doi.org/10.1590/1676-06032014009414Abstract: The Lowland Forest is one of the most disturbed and fragile ecosystems in the Atlantic Forest biome, yet little is known regarding its successional trajectory and resilience. We evaluated changes in species assemblages and forest structure of the canopy and understory along a successional gradient (young 21-yrs old forest, immature 34-yrs old forest and late successional 59-yrs old forest) aiming to assess changes in species composition and successional trajectory of different strata of secondary forests. A 0.1 ha plot (ten 10x10 m sub-plots) from each forest stand was surveyed for trees and shrubs with a diameter at breast height (DBH) > 4.8 cm (canopy) and for individuals with heights > 1 m and DBH , 4.8 cm (understory). A total of 3,619 individuals from 82 plant species were sampled. The successional gradient was marked by a unidirectional increase in species richness and a bidirectional pattern of density changes (increasing from young to immature forest and decreasing from immature to late successional forest). Community assemblages were distinct in the three forests and two strata; indicator species were only weakly shared among stands. Thus, each successional forest and stratum was observed to be a unique plant community. Our results suggest slight predictability of community assemblages in secondary forests, but a relatively fast recovery of forest structure.

Foram avaliadas alteraçõ es na composiçã o de espécies e a estrutura florestal do dossel e sub-bosque ao longo de um gradiente sucessional (floresta jovem-21 anos, floresta imatura-34 anos, floresta madura-59 anos) com o objetivo de verificar as mudanças na composiçã o de espécies e a trajetó ria sucessional de diferentes estratos destas florestas secundá rias. Uma parcela de 0,1 ha (dez sub-parcelas de 10x10 m) foi estabelecida em cada floresta, amostrando-se á rvores e arbustos com um diâ metro à altura do peito (DAP) > 4,8 cm (dossel) e para indivíduos com altura . 1 m e DAP , 4,8 cm (sub-bosque). Um total de 3.619 indivíduos de 82 espécies de plantas foram amostrados. O gradiente sucessional foi marcado por um aumento unidirecional na riqueza de espécies com o tempo, e um padrã o bidirecional de mudanças de densidade (aumentando da floresta jovem para a imatura e diminuindo da imatura para a madura).

“…Todavia, ainda que estejam presentes em proporção inferior à da mata nativa, a maioria das plantas regenerantes na área restaurada tem dispersão zoocórica. Ferreira et al (2010), em avaliação da regeneração natural em área em restauração de aproximadamente 13 anos de idade, também observaram a predominância de espécies zoocóricas na regeneração natural (62,5%), o que é esperado em florestas tropicais maduras (Silva 2006) ou secundárias (Liebsch et al 2008). A zoocoria é a forma de dispersão mais frequente em florestas tropicais (Reis & Kageyama 2008).…”

-(Restored versus reference ecosystem: case study of plant community at a riparian forest in the Cerrado region, Assis, São Paulo State, Brazil). Whether or not the structure and composition of natural ecosystems can be recovered by ecological restoration is a controversial issue, and the relative contribution of the planted species or seed sources from the vicinity has rarely been assessed. We compared the understory of a planted and a native riparian forest on the basis of density, richness and proportions of functional attributes of individuals and species. Floristic analyses included the set of species planted. After ten years, richness of the community being restored is not far from the reference, but proportions of functional attributes differ between native and planted forest. More than 30 years are estimated to recover understory density. The dominance of immigrating species (74% of individuals and 85% of species) indicates that the regional species pool has a much stronger influence than the set of species planted to build a community assembly in the forest undergoing restoration. Key words: Cerrado, natural regeneration, restoration ecology, restoration goals, riparian forest RESUMO -(Ecossistema em restauração versus ecossistema de referência: estudo de caso da comunidade vegetal de mata ciliar em região de Cerrado, Assis, SP, Brasil). Se a estrutura e a composição de espécies dos ecossistemas naturais podem ou não ser recuperadas por meio de restauração ecológica é tema controvertido, e a influência das espécies plantadas nesse processo raramente é avaliada. Comparamos a comunidade vegetal em regeneração sob mata ciliar sendo restaurada com a mata ciliar nativa e com o conjunto de espécies plantadas, pela densidade, riqueza, composição florística e atributos funcionais de indivíduos e espécies. Aos dez anos, a comunidade em restauração aproximou-se da referência em riqueza, mas diferiu em composição florística e proporção de espécies para alguns atributos funcionais. A densidade de regenerantes poderá levar mais de 30 anos para equiparação. Espécies imigrantes, não plantadas, corresponderam a 74% dos indivíduos e 85% das espécies amostradas no subosque da floresta plantada, demonstrando maior influência da diversidade remanescente na paisagem do que do conjunto de espécies plantadas na construção da comunidade em restauração.

The formation of secondary forest groups composed of distinct regeneration ages, as observed in the grouping analysis and ordinations of the arboreal habit, can be justified by the similarities of the soil characteristics within the groups (which is often a consequence of the close proximity of these areas).…”

Surveys were undertaken to examine the floristic changes during secondary succession in three areas of 12 and three of 20-year-old secondary forests in Pernambuco State, Brazil. Two hundred and six species were identified, with 136 being found in the 12-year-old secondary forest and 161 species in the 20-year-old forest. Fabaceae and Myrtaceae were the most important families, increasing in species numbers with regeneration age. Of the 216 species, 115 were trees, 48 shrubs, 16 herbaceous plants, and 24 woody lianas, without significant differences between the two regeneration site ages. NMDS analysis revealed a formation of two floristic groups, distinguishing secondary and mature forests, with a further division within secondary forests in accordance with the time since abandonment. Similarity analysis ANOSIM confirmed the significance of the groups, which had floristic composition significant distinct (R=0.96) and 63% of dissimilarity (SIMPER). However, the sharing of 68 arboreal species between the secondary and mature forests suggests a floristic convergence. DCA analysis of the arboreal component as well as the other plant habits suggested that the separation of the subgroups is correlated with physical and chemical variables of the soils. All of these results indicate that, within the chronosequence analyzed, the velocity and direction of the floristic composition during secondary succession was influenced not only by the time of their abandonment, but also by a wide range of environmental variables.
