“…Similarly to other studies areas of Rupestrian Savannah (Silva et al 1996;Amaral et al 2006;Miranda et al 2007Miranda et al , 2010Moura et al 2007Moura et al , 2010Oliveira and Martins 2007;Pinto et al 2009;Abreu et al 2012;Santos et al 2012;Gomes et al 2016;Torres et al 2017), the families Myrtaceae, Fabaceae, Malpighiaceae and Erythroxylaceae were the richest families observed in the present study. These families were referred by Goodland and Ferri (1979) as "overrepresented" in the Cerrado.…”

“…Despite the fact that richness and density of the Rupestrian Savannah of Rio Paranaíba were statistically similar when compared to the other areas, the basal area was one of the smallest amongst the comparative studies (Felfili and Fagg 2007, Moura et al 2010, Gomes et al 2016. According to Ribeiro and Walter (2008), the woody individuals of the Rupestrian Savannah settle in the cracks between rocks and their density varies according to the availability of soil.…”

The flora of the Rupestrian Savannah (Cerrado Rupestre) is composed of widely distributed species and endemic species from high altitude rocky outcrops. The aim of this study was to characterise the floristic composition, structure and diversity of fragments of Rupestrian Savannah in south-eastern Brazil and to examine the similarity with other rupestrian cerrado vegetations and with cerrado sensu stricto on profound soils. For this, phytosociological parameters, evenness and diversity were calculated and compared with other studies. The survey exhibited 72 species, 45 genera, 30 families and high floristic similarity with cerrado on profound soils. There were no indicator species of the Rupestrian Savannah, but there were typical species of rocky environments. The basal area was significantly larger in the profound soil cerrado in relationship to the Rupestrian Savannah and evenness was lower in the Rupestrian Savannah of this study compared to others. These variables reflect the lower exploration capacity of the root of rocky environments. The highest similarity between the Rupestrian Savannah and cerrado on profound soils refers to the canga ferruginous nature, which represents the limit of the tableland of cerrado on the edge of the plateaus, allowing greater sharing of flora.

“…Esse resultado não seguiu o mesmo padrão para o estrato das arvoretas. GOMES et al (2016), estudando a dinâmica da vegetação em Cerrado sentido restrito, também encontraram maiores taxas de mortalidade nas classes de menor diâmetro. Entretanto, estes autores registraram taxas positivas para a maioria das classes, ao contrário do que aconteceu no presente estudo.…”

“…As mudanças no número de espécies em formações vegetais tropicais é frequentemente associada a dinâmica natural (GONZAGA, 2011). Nesse sentido, segundo Gomes et al (2016), a morte ou recrutamento de um pequeno número de indivíduos pode facilmente provocar, diminuir ou aumentar a riqueza de espécies. Além disso, a riqueza florística de determinado fragmento pode ser afetada por diversos fatores como tempo de regeneração, tamanho da área e principalmente pelo tipo e intensidade dos distúrbios.…”

O objetivo desse estudo foi avaliar as mudanças na composição florística em um fragmento de Floresta Estacional Semidecidual. No primeiro inventário realizado em 2011 foram alocadas 25 parcelas de 10 ×40 m. Foram mensurados todos os indivíduos vivos com diâmetro a altura do peito ≥ 5cm. O segundo inventário foi realizado em 2015, utilizando-se os mesmos critérios do inventário anterior, assim, foram incorporados os novos indivíduos (recrutas) que atingiram o diâmetro mínimo de inclusão. O correram mudanças na composição florística, a mortalidade dos indivíduos foi superior ao recrutamento, houve perda de cinco espécies e incremento de duas espécies. O número de espécies e a densidade dos indivíduos variaram com o tempo. As espécies que desapareceram eram representadas por poucos indivíduos. A perda de espécies refletiu no índice de diversidade de Shannon (H’) e equabilidade de Pielou, (H’passou de 4,05 para 3,99 e equabilidade de Pielou J’ de 0,83 para 0,82), no primeiro e segundo inventário respectivamente, mesmo assim, os valores apontam para uma diversidade florística elevada. As mudanças na composição florística não foram significativas, a perda de espécies teve relação com as menos representativas em número de indivíduos, entre os inventários a floresta se manteve estável.Palavras-chave: mortalidade, recrutamento, sucessão ecológica. VARIATIONS IN THE FLORISTIC COMPOSITION IN SEASONAL SEMIDECIDAL FORESTS IN CURVELO-MG ABSTRACT: The objective of this study was to evaluate the changes in floristic composition in a fragment of Seasonal Semideciduous Forest. In the first inventory carried out in 2011, 25 plots of 10 × 40m were allocated. All living individuals with a breast height diameter ≥5 cmwere measured. The second inventory was carried out in 2015, using the same criteria of the previous inventory, thus, were incorporated the new individuals (recruits) that reached the minimum diameter of inclusion. The floristic composition changes, the mortality of the individuals was superior to the recruitment, there were loss of five species and increase of two species. The number of species and the density of individuals varied over time. The species that disappeared were represented by few individuals. The loss of species reflected in the diversity index of Shannon (H ') and Pielou equability, (H' went from 4.05 to 3.99 and Pielou J 'equability from 0.83 to 0.82), in the first and second inventory respectively, even so, the values point to a high floristic diversity. The changes in floristic composition were not significant, the loss of species was related to the less representative in number of individuals, among the inventories the forest remained stable.Keywords: mortality, recruitment, ecological succession.
