“…Regarding the density of individuals (Table 1), the fragment agreed with general observations for Seasonal Semideciduous Forests (Abreu, Silva, & Silva, 2013;Souza, Meira Neto, & Souza, 2013;Corsini et al, 2014). The reduction of the density of smaller diameter trees and the growth of larger diameter trees are representative of areas in the recovery and in advanced successional stages (Fonseca & Rodrigues, 2000;Oliveira-Filho et al, 2007;Higuchi et al, 2008).…”

“…These remnants play an important role as ecological corridors that are able to provide gene flow between isolated populations, a critical factor for the conservation of many species (Silva & Tabarelli, 2000). Structural data comparisons are essential to assess the loss of biodiversity and the vulnerability of plant communities in fragmented areas and to evaluate potential losses and conserve natural resources in the long term (Corsini, Scolforo, Oliveira, Mello, & Machado, 2014).…”

ABSTRACT. This study was conducted in one region of a Seasonal Semideciduous Forest located in Tapurah (Mato Grosso State, Brazil) with the aim of studying its floristic and structural composition. The fixed area method was applied to 10 × 250 m clusters, allocating and measuring five clusters with five subunits of 500 m² each. Species with a diameter at breast height greater than or equal to 10 cm were considered, and the sample sufficiency of the floristic survey was verified by a species accumulation curve. The similarities between the sample subunits were calculated by the Jaccard Similarity Index, and the species diversity with the Shannon Diversity Index and Pielou Evenness Index. The horizontal vegetation structure was characterized by density, frequency, dominance and the values of ecological importance, and diametric distribution were assessed by the Spiegel procedure. The families Vochysiaceae, Fabaceae and Sapindaceae were highly represented, and Qualea paraensis, Aspidosperma discolor and Matayba arborescens were the most important species. A high diversity and low ecological dominance were found, and the diametric structure of the trees presented a negative exponential distribution. In general, the structure, floristic composition and richness of vegetation correspond to a forest with stable and autoregenerative community after selective logging.

“…According to Gomide et al (2006), the variation of species between communities can be represented and quantified through various ways, the most common being by means of diversity indices. Indices of Shannon, Simpson and Pielou are, respectively, mathematical formulations often used to quantify diversity, dominance and evenness of forest species (Gomide et al, 2006;Guedes & Krupek, 2016;Ariotti et al, 2016;Corsini et al, 2014).…”

“…It is expected that the forest species diversity presents variations among the forest formations, once they are composed by highly variable species richness, and located in distinct environmental conditions. Some studies in Minas Gerais demonstrate that diversity may range from 2.236 (Deciduous Seasonal Forest areas) up to 4.523, (Semideciduous Seasonal Forest areas) (Corsini et al, 2014). Gomide et al (2006) found indices ranging from 2.176 to 4.389 (Shannon), from 0.019 to 0.206 (Simpson), and 0.625 to 0.875 (evenness).…”

The state of Minas Gerais has a high ecological relevance mainly due to its forest species diversity. Understanding the spatialization of that diversity is of importance to develop environmental public policies. The hypothesis of this study is that the tree species diversity from different forest types, in the state of Minas Gerais, presents distribution with spatial dependence. Thus, the objective of this work was to prove that spatial dependence and to relate it between the forest types. Data from the project called "Forest Inventory of Minas Gerais" were used to calculate indices of Shannon, Simpson and Pielou. We used geostatistical and kriging tools to create spatial maps. As results, the mappings indicated that the state presents well-defined gradients of diversity and richness of forest species, increasing in North-South and from West-East directions. The spatial dependence and the spatialization of the tree species diversity show that the geostatistical modeling is a tool that supports the forest resource management. The maps of diversity can be used as indicators of potential areas for creating Conservation Units, establishing ecological corridors, besides supporting environmental policy development.

A análise fitossociológica bem como a composição florística de florestas naturais é de grande valor para compreensão da dinâmica das comunidades florestais. O presente trabalho teve como objetivo analisar uma área de floresta estacional decidual localizada no município de Santa Tereza no estado do Rio Grande do Sul. Foram instaladas 100 parcelas de 10 x 10 demarcadas em um hectare no interior da floresta, onde foram medidos e identificados todos os indivíduos com circunferência à altura do peito (CAP) ≥ 30 cm. O levantamento foi realizado adotando-se o método de parcelas contíguas, seguindo a metodologia de Muller-Dombois e Ellemberg (1974). A densidade total de 875 indivíduos por hectare, sendo 56 espécies, 46 gêneros e 30 famílias. As famílias Fabaceae e Euphorbiaceae apresentaram o maior número de espécies. A espécie Lonchocarpus campestres, apresentou o maior índice de valor de importância (IVI) e maior índice de valor de cobertura (IVC). O índice de diversidade de Shannon (H’) foi de 3,34 nats/ind. e o índice de equabilidade de Pielou (J) foi de 0,83. A maior parte dos indivíduos estão em classe de altura entre 8 e 10 m e classe de diâmetro entre 9 e 15 cm.
