“…The high representivity of just a few species in terms of their numbers of individuals and their importance values, as seen in the present study, is often observed in woody savanna communities of typical cerrado (Felfili & Silva Júnior 1993, Cardoso et al 2002, Campos et al 2006) and rocky outcrop cerrado (Amaral et al 2006, Viana & Lombardi 2007). There were, however, marked differences between the 10 most important species in the two cerrado communities, with only Qualea parviflora being of marked structural importance in both TC and RC sites.…”

Influence of edaphic variables on the floristic composition and structure of the tree-shrub vegetation in typical and rocky outcrop cerrado areas in Serra Negra, Goiás State, Brazil ABSTRACT -(Influence of edaphic variables on the floristic composition and structure of the tree-shrub vegetation in typical and rocky outcrop cerrado areas in Serra Negra, Goiás State, Brazil). The present study analyzed the influence of edaphic variables on the floristic compositions and structures of the arboreal and shrub vegetation of typical cerrado (TC) and rocky outcrop cerrado (RC) communities in the Serra Negra mountain range in Piranhas Municipality, Goiás State, Brazil. Ten 20 × 50 m plots were established in each community, and all individuals with minimum diameters ≥ 5 cm measured at 30 cm above soil level were sampled. Composite soil samples were collected at 0-20 cm depths in each plot for physical and chemical analyses. The proportions of above-ground rock cover work also estimated in each RC plot. A total of 2,009 individuals (83 species, 69 genera, and 34 families) were recorded. Qualea parviflora was the only species consistently among the 10 most structurally important taxa in both communities, and was considered a generalist species. The observed and estimated species richnesses were greater in RC than in TC, although plant basal areas and heights did not differ between them. There were positive correlations between rock cover × plant density and rock cover × basal areas. TWINSPAN and PCA analysis separated the TC and RC plots, and three RC habitat specialist species (Wunderlichia mirabilis, Norantea guianensis, and Tibouchina papyrus) were identified. Soil variables were found to have greater effects on the species compositions of the TC and RC sites than the geographic distances between sampling plots. According to CCA analysis, the exclusive (or more abundant species) of each community were correlated with soil variables, and these variables therefore determined the selection of some species and influenced the differentiation of the vegetation structures of the communities studied.

“…In addition, close to those found in studies in the formation of Cerradão (CAMPOS et al, 2006;RODRIGUES & ARAÚJO 2013). The CCA correlated Copaifera langsdorffii, Tapirira guianensis,Schefflera morototoni with soils of higher fertility and high aluminum content according to other studies of species distribution in the Seasonal Forest (DALANESI et al, 2004;TEIXEIRA & ASSIS, 2009).…”

The Cerrado biome presents different physiognomies distributed throughout several Brazilian states. Studies related to species distribution as direct environmental factors may subsidize forest restoration projects. The objective of this study wasto evaluate ecological and structural differences and determine the species distribution based on soil factors in two physiognomies types of Cerrado. Data sampling was conducted in the area of influence of the sugar cane industry in southwest of Goiás, Brazil. Soil samples were collected in those plots and analyzed chemically and psysically. The results of the soil characteristics were useful to verify if the species distribution correlate with soil patterns through canonical components analysis (CCA).The structural aspects were higher in the plots identified as seasonal forest. Although the Ecological aspects, such as species diversity, were higher in the cerradão. The CCA showed a positive correlation between the tree species distribution with physicochemical characteristics of soil. The analysis showed a positive correlation between the distribution of tree species and the physicochemical characteristics of the soil. A group of species was related to higher fertility in the soil and clay content. Another group was correlated with low fertility and higher sand content soils.

“…As famílias botânicas mais expressivas em relação à riqueza foram: Fabaceae (34%) seguida de Anonnaceae (8,5%) e Anacardiaceae (6,5%) perfazendo 49% de todos os indivíduos amostrados. Fabaceae é uma das quatro famílias mais representativas da flora mundial e, no Cerrado, sua representatividade já foi reportada por trabalhos de diversos autores como Goodland (1970), Balduino et al, (2005), Campos et al (2006), Ssouza et al 2008, Souza et al (2010), Ferreira et al (2014) e Giacomo et al, (2015). A família Annonaceae é uma das mais ricas em número de espécies (CHATROU et al 2004), e não costuma figurar dentre as mais representativas em levantamentos pelo Cerrado, sendo mais abundante no bioma Amazônico (MAAS et al 2012).…”

Entender a composição florística e a estrutura das florestas é um dos principais passos para a conservação dessas áreas. Para isso, realizou-se o levantamento da comunidade arbórea de Cerradão situado na Reserva de Desenvolvimento Sustentável Legado Verdes do Cerrado, em Niquelândia Goiás. Foram alocadas 20 parcelas de 10x10m distribuídas em quatro sítios com cinco parcelas cada um. Todos os indivíduos arbóreos que apresentaram diâmetro à altura do peito (DAP) ≥ 5 cm foram amostrados. Analisou-se parâmetros fitossociológicos e florísticos. A similaridade florística entre os sítios e entre as parcelas também foi analisada. Foram registrados 305 indivíduos distribuídos em 76 espécies, 60 gêneros e 31 famílias botânicas. O índice de diversidade de Shannon (H'=3,83 nats.ind-1) e equabilidade de Pielou (J'=0,88) ficaram acima de valores encontrados para outros estudos no Cerradão. As espécies com maiores IVI (índices do valor de importância), foram: Tachigali vulgaris, Xylopia aromatica, Vatairea macrocarpa, Curatella americana, Hirtella glandulosa, Pterodon emarginatus, Myrsine gardneriana, Andira paniculata, Tapirira guianensis e Bowdichia virgilioides. A distribuição diamétrica apresenta uma forte assimetria positiva, onde a segunda e a terceira classe são maiores que as demais, não apresentando uma distribuição de Jreverso, usualmente encontrada em Florestas tropicais naturais. A análise de Sorensen indica alta similaridade florística entre os sítios 10 e 11 e destes com o sítio 12. O sítio 09 apresentou 25% da sua flora distinta dos demais com espécies típicas florestais. A área estudada é rica e diversa e abriga várias espécies protegidas, justificando a necessidade de sua conservação.
